1. Introduction
Economic infrastructure companies, electricity companies among
them, share a feature: they perform an assigned specific function in a
specific territory using sophisticated, unique and expensive
infrastructure. Real property of such companies makes the biggest share
in the corporate capital structure and is created through a long-term
operating process. It is difficult, and often inexpedient, to compete
with economic infrastructure companies because normally one
infrastructure company of a respective branch operates in a certain
territory, which may be a city, a district, a region or another
administrative division, and satisfies the needs of the economy and
residents of such territory. Management of infrastructure companies and
of their operating costs must include management of the structure and
value of fixed assets. Although economic infrastructure companies are
usually a part of the state-controlled public sector, improved practice
of their management may make them effective competitors of private
companies.
It is difficult to monitor the property value in infrastructure
companies. Special-purpose property (e.g. pipelines, electric
transmission and distribution lines, transmission substations, pumping
stations, etc.) is rarely sold as individual property items and
generally is not displayed in market; thus a database of such property
sales is not available, though such database would facilitate
measurement of preliminary property value. Therefore, a separate
property valuation procedure is required in order to learn the value of
special-purpose property controlled by a company. Practical valuation of
special-purpose property usually depends on: the professional qualities
of a specific company or appraiser involved in property valuation; the
selected assumptions; and possibilities to learn about and compare
practices of such property valuation in various countries. Regular
property valuation methods do not account for the trends of changing
value, and economic methods based on subjective assumptions of
appraisers fail to ensure objective valuation. However, property
valuation in infrastructure companies, both based on traditional
property valuation methods and on contemporary methods involving
mathematical statistics or multiple criteria analysis, must include
analysis of the specific features and environment of infrastructure
companies, as these factors have significant impact on the activities of
such companies.
Such scientists as Bradley, Fulmer, Rosen, Lane, Navickas, who are
considered to be the originators of studies in this area, analyse specific features of activities of infrastructure companies. The
scientists have defined infrastructure as a set of general conditions,
which may facilitate development of private companies within the main
economic branches and are designed to satisfy the needs of the entire
society. Infrastructure is specified as a set of economic resources, the
functioning of which determines the level of active economic practices
(Bradley et al. 2004). There are two main branches of infrastructure:
economic and social. Economic infrastructure covers all branches which
provide for activities within the economic process (Navickas,
Cibinskiene 2004). Activities of infrastructure companies are related to
"providing" economic branches, product transfer and storage
processes, as well as collection, processing and information transfer
processes. Activities of infrastructure companies are inseparable from
safeguarding of public interests. Jan Eric Lane analyses the principles
of operation and management of infrastructure companies, as well as the
influence of state control and regulation on infrastructure companies in
order to safeguard public interest. The author specified that two
parameters determine the efficiency of companies which safeguard public
interest: the amount of resources consumed in production of one product
item and the degree at which an organisation achieves its goals (Lane
1995). Resource amount management means management of their value as
well.
Recently, the impact of infrastructure companies, electricity
companies among them, on environment came into spotligh, when the
significance of environmental factors shaping the quality of life was
assessed. However, usually only the amount of pollution emissions and
implementation efficiency of environmental programmes are considered in
analysis of the effect on environment of energy sector objects. Various
countries take up studies in order to learn about the influence of the
location of energy sector objects on the value of neighbouring property.
For example, analysis of the impact of the wind park in Great Britain on
the price of nearby residential houses has shown that the traditional
value criteria, such as the type of ownership and sales timing, are the
main factors influencing the price level (Sims et al. 2008). In
contrast, such objects as high voltage electricity transfer lines,
thermal power plants, sewage management companies or highways make
negative impact on the life quality of people in the neighbourhood and
the level of property prices (Des Rosiers 2002). When solving a property
valuation task, it is equally important to measure both economic
parameters and perspectives of company's activities and the
environmental aspects, to determine the factors which affect the value,
as well as the impact of infrastructure objects themselves on
environment (Rosen 2002). In future, solutions of property valuation
problems will focus on the importance of assessment of environment
factors and the environmental aspect.
The pollution emissions of economic infrastructure objects
attributed to electricity, heating, gas supply, utility, communication
and transport infrastructure, the influence of electromagnetic field generated by electricity transmission lines, waves of communication
objects, transmission of flammable and potentially dangerous substances
through main pipelines and other activities affect environment at
various degrees. Besides, the location of unattractive and
environmentally-aggressive special-purpose objects makes negative impact
on activities of nearby residents (e.g. quality of agricultural
products), on their accumulated property, on its attractiveness and on
price levels (Gwartney et al. 1997). Property which is close to sewage
treatment plants, high voltage substations, thermal power plants or
waste combustion companies will have lower value compared to the same
type of property neighbouring with objects which do not pollute environment and located in a place with well-developed infrastructure of
social services. Therefore, proper environment indicators, which have
the biggest impact on activities of the analysed object, must be
selected and their weights assessed for property valuation in
infrastructure companies, energy companies among them. Then valuation
methods, which allow to integrate values of the effect of environment
factors into the value of the analysed property, can be selected and
applied.
Chapter 2 of this paper presents the Analysis Model for Environment
Factors, which affect electricity companies, developed by the authors;
its main elements are based on the analysis and simulation of macro,
meso and microlevel variable factors affecting the efficiency. Also,
chapter describes the model's elements characterising the
environment of the analysed sector. Chapter 3 dwells on the suggested
multiple criteria designing methods: the expert method, the multiple
criteria complex proportional evaluation method and the multiple
criteria methods for the measurement of the utility degree and market
value of real estate. Chapter 4 handles a practical task: the utility
degree and market value of the selected electricity companies was
measured using the Analysis Model for Environment Factors and multiple
criteria analysis methods.
2. Integrated analysis model for environment factors which affect
energy companies
Business value is typically multidimensional and indefinite; thus,
it is expedient to use several methods in the valuation and to make
several interrelated estimates of value aspects. Although scientific and
methodological literature suggests various valuation methods, there is a
lack of valuation methodology which would regulate valuation of
special-purpose property in large economic infrastructure companies and
could be used as a basis for integrated assessment of environment
factors affecting companies or their property value. Numerous valuation
methods currently suggested for practical application can be divided
into three main groups: property, market and income valuation methods.
However, these methods do not facilitate integrated assessment of macro,
meso and microfactors affecting property values, as well as of goals and
influence of stakeholder groups. The method for the valuation of
corporate property or business must be selected considering:
-- the purpose of valuation;
-- the business field and property group to which belongs the
valuated object;
-- which property value is relevant;
-- which value is the best to express property value in open
market;
-- which environment factors have the biggest impact on changing
value.
In order to find the instruments suitable to measure the factors
which affect property value of energy companies and which can best
reflect the impact on value and to foresee trends of value changes, we
suggest an Analysis Model for Environment Factors in this sector;
components of the model integrate the analysis of a company's
condition and the value-affecting variable factors of macro, meso and
microenvironment. The theoretical Analysis Model for Environment Factors
affecting company's value is provided below in Fig. 1.
The analysis of factors affecting a company's value can be
divided into four main areas:
1. Analysis of a company's condition within the analysed
period including internal processes of the company's financial
state, property structure, technical condition, etc.;
2. Comparative analysis of the same type of corporate operating
indicators and environment factors;
3. Analysis of macro, meso and microlevel environment factors
affecting operating efficiency;
4. Analysis of the impact of groups which affect decisions.
[FIGURE 1 OMITTED]
The above model has already been applied in the development of
Lithuanian construction industry (Zavadskas, Kaklauskas 2008), in
sustainable development of Vilnius (Zavadskas et al. 2007), in housing
credit access (Zavadskas et al. 2004) and in facilities management (Lepkova et al. 2008).
2.1. Analysis of a company's condition within the analysed
period First, considering the valuation task, an analysis of a
company's financial state, indicators of financial activities and
property structure is performed. Corporate operating efficiency is
defined by the management of cash flows, the balance of income-to-cost
ratio, management of material resources, ability to achieve goals,
efficient project management and other types of internal information
which may affect corporate value. An important part of this analysis is
the analysis of property structure, because property, which consists of
special-purpose infrastructure, is the decisive element which is the
basis for activities in energy sector. The main features of such
property are its complexity and specific nature. Poorly developed
infrastructure seriously limits possibilities to offer services and
causes system malfunctions, growing demand for production and
consumption cause backlogs and a company fails to use the potential
granted by the market. In electricity sector, infrastructure and
buildings with equipment, which belong to power plants, comprise up to
90% of a company's property; electricity transfer lines and the
infrastructure of distributions lines comprise up to 80% of corporate
fixed assets. Besides, repair and maintenance of property account for a
large lump of operating costs in this sector. Issues related to facility
and infrastructure management, investments into infrastructure
development, modernisation and upgrade of the available infrastructure
using state-of-the-art technology make up the main part of processes of
corporate management in energy sector. When electricity companies are
being divided and restructured, when separate types of activities
undergo the process of privatisation or investments are planned,
separate infrastructure items or property items are the objects of
valuation, and their value depends on the environment factors which
affect the value of the entire property. The analysis of a
company's condition within the analysed period, as well as the
analysis of its cash flows, property and internal processes, is a basis
to come up with preliminary conclusions on the company's value.
2.2. Comparative analysis of the same type of corporate operating
indicators and environment factors
To validate preliminary conclusions and to make them more reliable,
an analysis of comparative examples is made. The analysis of countries
with similar economic levels and companies operating within the same
economic sector guarantees more objective results. Historical aspects of
the sector's development are also considered. Lithuanian
electricity companies or a group of companies can be compared to
electricity companies of Eastern Europe (Czech Republic, Poland,
Slovakia, Hungary), the Baltic States (Latvia, Estonia) or the
Scandinavian Countries (Finland, Sweden). The results of the comparative
analysis and the accumulated materials help to determine the development
trends of the analysed sector: general economic trends at national or
regional level and trends within the same type of sectors in the
selected countries are compared, differences with Lithuania are
specified.
2.3. Analysis of environment factors affecting corporate operating
efficiency Using expert methods, the next phase determines macro, meso
and microlevel factors, as well as the systems and subsystems of
defining indicators, which provide a thorough description of activities
of the sector in which the company operates. The following structural
elements of the developed model make the biggest impact on its
effectiveness and efficiency:
-- macro, meso and microenvironment;
-- groups taking part in the decision-making process.
Macroenvironment Factors
Macrolevel factors define the level of national or industrial
efficiency. Besides, macrolevel factors affect the development level of
separate industrial branches. The efficiency of electricity companies
significantly depends on the integrated effect of macrolevel variable
factors, such as national economic, political and cultural development
level, legal acts regulating activities, market, tax system,
possibilities and conditions within the loan market, inflation,
possibilities to acquire resources, etc. The efficiency level of a
branch changes depending on the integrated effect of macrolevel factors:
the need for energy resources decreases or increases.
PEST analysis (Political-Legal, Economic, Socio-Cultural and
Technological Forces) is the most popular analytic technique in studies
of macroenvironment of electricity companies, as well as companies of
other industrial branches. This analysis covers four aspects of
macroenvironment: political and legal, economic, socio-cultural and
technological. PEST analysis applies quantitative (extrapolation,
mathematical modelling, etc.) and qualitative (scenarios, Delphi, etc.)
forecasting methods to analyse the environment. The analysis of
macroenvironment must include a thorough analysis of political-legal
environment, because activities of energy companies usually obey strict
legal regulation. Their activities are regulated by EU and national
legal acts. Recently, EU members started harmonisation of these legal
acts and their transfer into national legal bases. This process
simplifies the analysis of legal environment.
Expert assessment of macroenvironment criteria revealed that EU
regulation of activities, which attempts to create a competitive market
of electricity supply and distribution, as well as technological changes
and standardisation of environmental requirements are the most
significant criteria affecting activities of energy sector. Whereas
activities within the energy sector are relevant to all aspects of
public life, the impact of public opinion on activities was specified as
a significant criterion (see the research results in Chapter 5).
Mesoenvironment Factors
The analysis of mesolevel environment is oriented towards the goals
of a specific economic sector, its role in national economy and the
branch, features which shape the type of activities, profit, processes
within a specific branch, impact of the processes on environment,
fulfilment of the sector's social role, documents regulating
activities and relations with state institutions. It is an intermediate
level between microeconomics and macroeconomics.
In order to make a consistent analysis of mesoenvironment, the
relation between the environment of the analysed economic object and
economy must be examined. Besides, the specific environment, in which
the analysed company operates, must be assessed. The analysis of this
environment is based on the analysis of such factors as institutions
involved in legislation (legal and normative acts), supervision and
control at various levels. There is a direct relation between the
decisions of institutions together with their legislative processes
(legal acts which regulate corporate activities) and corporate plans and
decisions. Vasiliauskas applied Porter's National Diamond to
present the specific features of the interaction between companies and
the national economy management, thus pointing out the relation between
macroenvironment factors and specific environment of institutions
(Vasiliauskas 2005). Indicators which assess the ability of a specific
analysed object to achieve economic goals when it solves environmental
issues and implements resource-saving manufacturing measures and
technologies, as well as renewable energy sources, are significant in
the analysis of mesolevel factors. Educational background of society, as
well as active contribution to the solution of quality issues related to
residential and work environment, also makes impact. This expands the
limits of macro- and mesoenvironment and the influence of these factors
on operating efficiency of energy companies. It is at the mesolevel that
the environmental dimension and the external effect (the effect of
by-products and pollution on the environment) of activities are analysed
in infrastructure companies within the energy sector. The expert study
of the influence of mesoenvironment factors of energy companies has
shown that respondents from various social groups consider profitability
and introduction of environmentfriendly technologies as the most
significant mesoenvironment criteria in activities. It is important to
note that the criterion of corporate social responsibility is also
considered rather significant (see Chapter 5).
Environmental Factors
Making the analysis of activities within the electricity sector, it
is worthwhile to make a more thorough assessment of environmental
factors. Companies within this sector make a considerable impact on the
environment. Organic fuel, which is of limited quantities, is widely
used in the process of energy production. Environment is polluted by
S[O.sub.2], C[O.sub.2], N[O.sub.x] and other types of particulate
matter, which are a by-product of the process of energy production and
can affect soil, water, air and biological cycle and generate huge
amounts of hard waste (Norvaisa, Galinis 2004). Despite high economic
efficiency parameters, nuclear energy includes a complex and expensive
burying of radioactive waste accumulated during the energy production
cycle. Even electricity transfer through open high voltage lines
generates electromagnetic fields, the effect of which is assessed, and
legal acts regulate the conditions for operation of such objects.
Therefore, cleaner production in the electricity sector is a very
effective and economically efficient course of activities.
The Sixth Environment Action Programme of the European Community
sets the environmental goals and priorities, which are a part of the EU
Sustainable Development Strategy. The programme also foresees measures
to achieve these goals. For many years already, EU states apply
environmental measures based on market factors, such as environmental
taxes, in order to increase the market share of products, processes and
services, which are more acceptable in terms of environment protection.
Such taxes encourage companies to allocate more funds to research and to
invest into technologies less damaging to environment or requiring fewer
resources (Staniskis, Stasiskiene 2006).
In Lithuania, the analysis of environment factors yet rarely
includes assessment of external environment pollution costs. Although
Lithuanian power plants pay taxes for pollution emissions into
atmosphere, these taxes are, however, rather small compared to the
external costs per one ton of pollution emitted into the atmosphere.
Increased pollution taxes would affect the cost structure of energy
companies, especially in 2010 and later, when Lithuanians will no longer
have the source of cheap and rather clean energy, i.e. Ignalina Nuclear
Power Plant. Therefore, the analysis of corporate activities must also
consider increasingly strict environmental requirements and the foreseen increase of pollution taxes.
Microlevel Factors
Microenvironment factors are related to a specific firm or company
and affect its ability to achieve its goals. These factors embrace all
things related to customer value delivery: activities of the company
itself, suppliers (from energy sources to various support services),
companies within the supply and distribution chain, competitors,
consumers and society. These factors depend on macro and mesolevel
factors.
Energy sector must continuously keep high levels of infrastructure
maintenance, must modernise and develop objects, must implement
innovative technologies and management processes. The efficiency of the
sector's development and implementation of investment projects is
affected by various microlevel factors, such as: land prices; extended
procedures of territorial planning and preparation of special and
detailed plans; efficiency level of the process related to the supply of
technologies, mechanisms and equipment for reconstruction and
modernisation; funding conditions of development projects; etc. During
the survey, respondents also stressed the importance of the experience
of top managers and readiness of personnel to apply innovations.
2.4. Analysis of groups affecting decisions
The analysis of environment factors cannot be thorough until
stakeholder groups, which affect activities and decisions, are
considered in assessment of the specific environment of energy sector.
Such scientists compiled a list of questions which help to identify the
main stakeholder groups, the type of their influence, their level, their
expectations and requirements, as well as possible outcomes
(Arimaviciute 2005). The author suggest distinguishing the following
types of stakeholder groups based on the results of the analysis and
assessment:
-- potentially problematic;
-- hostile;
-- rather insignificant;
-- supporting.
The analysis and the obtained results help to assess the
requirements and expectations of various groups, to evaluate them and to
search for the ways to affect hostile groups or to help and strengthen
the supporters (Arimaviciute 2005). In the energy sector, the same
stakeholder group may represent various interests depending on the type
of company's activities. For example, residents usually support
companies which use renewable resources but are against construction of
wind parks in the neighbourhood of their property. The suppliers of raw
materials are interested in the development of the thermal energy sector
and challenge the development of nuclear energy.
Interrelations of stakeholder groups are shown in Fig. 2.
The activities within the energy sector are controlled and
coordinated by the State and various EU institutions. Various
institutional participants--starting with international alliances,
association committees and ending with trade unions--have a direct
influence on the operation of the sector's companies. The following
parties have vested interests in activities of the energy sector:
suppliers of resources and raw materials which affect energy prices;
manufacturers of devices and equipment; organisations offering
designing, construction and other services.
Consumers are also important members of the energy sector. They may
be industrial companies and household consumers. Although lately energy
consumption was increasing in our country, growing prices of raw
materials, as well as electricity production, distribution and supply,
make various groups observe the processes within the energy sector and
participate in management bodies of energy companies. Natural
monopolies, which dominate Lithuanian electricity sector, basically
eliminate competitive environment and the consumer's right to
choose. Active involvement of stakeholder groups and political
organisations affects the process of market liberalisation.
3. Measurement of the utility degree and market value using
multiple criteria analysis methods
Multiple criteria decision making methods have been applied to a
variety of problems, such as maintenance outsourcing (Almeida 2005),
construction and real estate (Kaklauskas et al. 2005, 2007a, b;
Zavadskas et al. 2008a), maintenance strategy (Almeida, Bohoris 1996),
water supply management (Morais, Almeida 2007), project risk assessment
(Zeng et al. 2007), multi-criteria risk analysis (Brito, Almeida 2008),
service outsourcing contracts (Almeida 2007) and construction bidding
(Seydel, Olson 2001).
[FIGURE 2 OMITTED]
The efficiency must be analysed within the limits determined by
micro, meso and macrolevel factors in order to describe the operating
efficiency of an energy sector company. These factors constantly change.
Changes of these factors also mean changes in the efficiency degree of
the analysed branch. Having assessed the impact of macro, meso and
microlevel factors and stakeholder groups, it is possible to determine
the influence of the factors on corporate operating processes and on the
value. The analysis must include formulation of possible variants of
organisational or corporate strategy in the analysed sector; these
variants must be evaluated on the basis of multiple criteria analysis
methods and the most efficient variants must be selected. Organisations
or companies cannot adjust or change macro-, meso- or microlevel
variables, but can understand their effect, assess them, forecast
possible changes and mitigate risks in the implementation of various
projects (Kozlinski, Guseva 2006).
In order to process the information about the effect of environment
factors and to determine their impact on value, it is expedient to use
contemporary multiple criteria analysis methods, that allow to analyse
sufficient amount of quantitative and qualitative indicators which
define objects, as well as to determine the utility degree and market
value of objects. Based on multiple criteria analysis methods, a company
or separate property items are appraised considering indicators which
describe the analysed object and affect its value; they are market
conjuncture, quantitative (number of property items, territorial
coverage, length and amount of engineering infrastructure objects),
qualitative (condition, modernisation, degree of technological novelty,
environment protection, reliability, etc.), political-legal (laws,
norms, regulations, limitations, restrictions) and other indicators.
Lithuanian scientists Zavadskas and Kaklauskas suggested the
following multiple criteria methods for the comparison of alternative
real estate items, for the measurement of the utility degree and for the
measurement of the market value (Zavadskas et al. 2008a, b, 2001;
Kaklauskas et al. 2006, 2007a, b; Banaitiene et al. 2008):
-- setting of weights of complex indicators considering their
qualitative and quantitative characteristics;
-- multiple criteria complex proportional evaluation method;
-- multiple criteria method for the utility degree and market value
measurement of real estate items.
The developed Analysis Model for Environment Factors helps to
determine the weights of operating indicators and environment effect
indicators of the analysed objects. The environment of the analysed
electricity sector, as well as energy sector objects, has its peculiar features, is affected by various market conjuncture conditions and is
influenced by stakeholder groups with confronting interests. These
features impede comparison of objects within the electricity sector.
However, using the complex analysis method, it is possible to measure
the utility degree of objects and to determine objective market value
for separate objects of electricity sector.
The complex analysis method is realised in the following main
stages:
1. Measurement and description of qualitative and quantitative
criteria which determine activities of a property object/set;
2. Development of an integrated database based on the obtained
description of analysed objects;
3. Use of multiple criteria analysis methods in order to measure
the utility degree and market value of the obtained alternatives.
Based on the obtained quantitative and conceptual description of
objects, an integrated database is developed, which provides
comprehensive descriptions of internal and external factors affecting
the value of the analysed objects and facilitates their multi-variant
designing and multiple criteria analysis.
3.1. Multiple criteria complex proportional evaluation method and
method for measurement of the utility degree and market value of objects
This method assumes direct and proportional dependence of the
significance and priority of the investigated versions on a system of
criteria adequately describing the alternatives and on values and
significances of the criteria. The system of criteria is determined and
the values and initial significances of criteria are calculated by
experts. All this information can be corrected by interested parties
(customers, users, etc.) taking into consideration their pursued goals
and existing capabilities. Hence, the assessment results of alternatives
fully reflect the initial data jointly submitted by experts and
interested parties.
The determination of the significance and priority of alternatives
is carried out in four stages.
Stage 1. The weighted normalized decision-making matrix D is
formed. The purpose of this stage is to receive dimensionless weighted
values from the comparative indexes. When the dimensionless values of
the indexes are known, all criteria, originally having different
dimensions, can be compared. The following formula is used for this
purpose:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (1)
where [x.sub.ij] is the value of the i-th criterion in the j-th
alternative of a solution; m--the number of criteria; n--the number of
the alternatives compared; [q.sub.i]--significance of i-th criterion.
The sum of dimensionless weighted index values dij of each criterion
[x.sub.i] is always equal to the significance [q.sub.i] of this
criterion:
In other words, the value of significance [q.sub.i] of the
investigated criterion is proportionally distributed among all
alternative versions aj according to their values [x.sub.ij].
Stage 2. The sums of weighted normalized indexes describing the
j-th version are calculated. The versions are described by minimizing
indexes [S.sub.-j] and maximizing indexes [S.sub.+j].
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (2)
The lower value of minimizing indexes is better. The greater value
of maximizing indexes is better. The sums are calculated according to
the formula:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (3)
In this case, the values [S.sub.+j] (the greater is this value
(project 'pluses'), the more satisfied the interested parties
are) and [S.sub.-j] (the lower is this value (project
'minuses'), the better is the goal attainment by the
interested parties) express the degree of goals attained by the
interested parties in each alternative project. In any case the sums of
'pluses' [S.sub.+j] and 'minuses' [S.sub.-j] of all
alternative projects are always respectively equal to all sums of the
significances of maximizing and minimizing criteria:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (4)
In this way, the calculations made may be additionally checked.
Stage 3. The significance (efficiency) of comparative versions is
determined on the basis of describing positive projects
('pluses') and negative projects ('minuses')
characteristics. Relative significance [Q.sub.j] of each project
[a.sub.j] is found according to the formula:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (5)
Stage 4. Priority determination of projects. The greater is the
[Q.sub.j], the higher is the efficiency (priority) of the project.
The analysis of the method presented makes it possible to state
that it may be easily applied to evaluating the projects and selecting
most efficient of them, being fully aware of a physical meaning of the
process. Moreover, it allowed to formulate a reduced criterion [Q.sub.j]
which is directly proportional to the relative effect of the compared
criteria values [x.sub.ij] and significances [q.sub.i] on the end
result. Calculation of the weighted normalized decision matrix are
presented in Table 1.
3.2. A method of defining the utility and market value of property
Significance [Q.sub.j] of property [a.sub.j] indicates satisfaction
degree of demands and goals pursued by the interested parties--the
greater is the [Q.sub.j], the higher is the efficiency of the property.
In this case, the significance [Q.sub.max] of the most rational property
will always be the highest. The significances of the remaining property
are lower as compared to the most rational one. This means that total
demands and goals of interested parties will be satisfied to a smaller
extent than it would be in the case of the best property.
The degree of property utility is directly associated with
quantitative and conceptual information related to it. If one property
is characterized by the best comfortability, aesthetics, price indices,
while the other shows better maintenance and facilities management
characteristics, both having obtained the same significance values as a
result of multiple criteria evaluation, this means that their utility
degree is also the same. With the increase (decrease) of the
significance of the property analyzed, its degree of utility also
increases (decreases). The degree of property utility is determined by
comparing the property analysed with the most efficient property. In
this case, all the utility degree values related to the property
analyzed will be ranged from 0% to 100%. This will facilitate visual
assessment of property efficiency.
The degrees of utility of the property considered as well as the
market value of a property being valuated are determined in seven
stages.
Stage 1. The formula used for the calculation of property [a.sub.j]
utility degree [N.sub.j] is given below:
[N.sub.j] = ([Q.sub.j] : [Q.sub.max]) * 100% , (6)
here [Q.sub.j] and [Q.sub.max] are the significances of the
property obtained from the equation (5).
The degree of utility [N.sub.j] of property [a.sub.j] indicates the
level of satisfying the needs of the parties interested in the property.
The more goals are achieved and the more important they are, the higher
is the degree of the property utility. Since clients are mostly
interested in how much more efficient particular property is than the
others (which ones can better satisfy their needs), then it is more
advisable to use the concept of property utility rather than
significance when choosing the most efficient solution.
The degree of property utility reflects the extent to which the
goals pursued by the interested parties are attained. Therefore, it may
be used as a basis for determining property market value. The more
objectives are attained and the more significant they are, the higher
will be the property degree of utility and its market value.
Thus, having determined in such a way the ratio of degree of
utility and market value of property, one can see what complex effect
can be obtained by investing money into the property. There is a
complete clarity where it pays better to invest money and what is the
efficiency degree of the investment.
Stage 2. The efficiency degree [E.sub.ji] of money invested into
property [a.sub.j] is calculated. It shows by how many percent it is
better (worse) to invest money into property [a.sub.j] compared with
property [a.sub.i]. [E.sub.ji] is obtained by comparing the degrees of
utility of the property considered:
[E.sub.ji] = [N.sub.j]--[N.sub.i]. (7)
The received results are presented as a matrix clearly showing
utility differences of the property (see Table 2).
Stage 3. The average deviation [k.sub.j] of the utility degree
[N.sub.j] of the property [a.sub.j] from the same index of other
property (n--1) is being calculated.
[k.sub.j] = [n.summation over (i=1)] [E.sub.ji]: (n - 1). (8)
Stage 4. The development of a grouped decision making matrix for
property multiple criteria analysis. The market value of a property
being valuated is calculated according to a block-diagram presented in
Fig. 3.
At the beginning, a grouped decision making matrix for property
multiple criteria analysis is developed (see Table 3), the first
criterion of which is based on the actual purchasing/selling prices of
the property compared and the value of a property being valuated. The
initial value of property being valuated is obtained from the following
equation:
[MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII.] (9)
In this matrix, property a1 to be valuated should be assigned the
market value ([x.sub.11-R]). Other comparison standard property
([a.sub.2]--[a.sub.n]) were sold, their purchasing/selling prices
([x.sub.12]--[x.sub.1n]) known. All the values and significances of the
criteria related to other property are also known (see Table 3).
The problem may be stated as follows: what market value
[x11.sub.-R] of valuated property a1 will make it equally competitive on
the market with comparison standard property ([a.sub.2]--[a.sub.n])?
This may be determined if a complex analysis of the benefits and
drawbacks of the property is made.
[FIGURE 3 OMITTED]
Using a grouped decision making matrix (see Table 3) and the
equations 1-9 the calculations are made.
Stage 5. The corrected value [x.sub.11-p] of property to be
valuated a1 is calculated:
[x.sub.11-p] = x11 * (1 + [k.sub.1] : 100) (10)
Stage 6. It is determined whether the corrected value [x.sub.11-R]
of property being valuated a1 had been calculated accurately enough:
[absolute value of [k.sub.1]] < s, (11)
where s is the accuracy, %, to be achieved in calculating the
market value [x.sub.11-p] of a property a1. For example, given s = 0,5%,
the number of approximations in calculation will be lower than at s =
0,1%.
Stage 7. The market value [x.sub.11-R] of property [a.sub.1] to be
valuated is determined. If inequality 2.20 is satisfied the market value
of property [a.sub.1] may be found as follows:
[x.sub.11-R] = [x.sub.11-p]. (12)
If inequality 11 is not satisfied, this means that the value of
property being valuated had not been calculated accurately enough and
the approximation cycle should be repeated. In this case, the corrected
value [x.sub.11] = [x.sub.11-p] of property being valuated is
substituted into a grouped decision making matrix of property multiple
criteria analysis and the calculations according to the formulae 1-9
should be repeated until the inequation 11 is satisfied.
Solving the problem of determining the market value [x.sub.11-R] of
a property [a.sub.1] being valuated, which would make it equally
competitive on the market compared with the property
([a.sub.2]-[a.sub.n] ) already sold, a particular method of defining the
utility degree and market value of property was suggested. This was
based on a complex analysis of all the benefits and drawbacks of the
property considered.
According to this method the property utility degree and the market
value of property being estimated are directly proportional to the
system of the criteria adequately describing them and the values as well
as significances of these criteria.
The complex proportional valuation method is used in the valuation
of economic infrastructure energy companies to determine the priority of
objects selected for analysis, as well as their utility degree, which
directly depends on the system of criteria defining the selected objects
and on the value and weight of these criteria. The system of criteria,
which define objects, is based on expert evaluation.
4. Measurement of the utility degree and market value of energy
objects using multiple criteria analysis methods
Four objects of energy sector were selected for the practical task
of multiple criteria analysis; they represent traditional and
alternative types of energy production: Kruonis Pumped-storage
Hydroelectric Power Plant, Kaunas Hydroelectric Power Plant, Lithuanian
Power Plant and the Experimental Geothermal Power Plant.
Kruonis Pumped-storage Hydroelectric Power Plant (Fig. 4) is an
engineering hydrotechnical complex consisting of two water storages (the
upper and the lower reservoir), four connecting pipelines, ditches,
hydro-aggregates, as well as hydroelectric technical facilities
(embankments, dikes, platforms) and equipments. The power plant was
launched in full power in 1998. Whereas Kruonis HAE ensures energy
balance in the common energy system and only a small part of the
produced electricity is sold at the electricity auction, its rated
potential is underused.
[FIGURE 4 OMITTED]
Kaunas Hydroelectric Power Plant, which was constructed and
launched in 1960, is the biggest power plant that uses renewable
resources in Lithuania (Fig. 5). The facilities of the hydroelectric
power plant include auxiliary structures of the power plant and
hydrotechnical buildings: dam, embankments and dikes. The machinery
plant located in the dam contains hydrotechnical equipment, turbines and
generators. This object is especially attractive in economic and
environmental terms. The power plant produces over 80% of our national
energy based on renewable resources. However, the amount of produced
electricity depends on the seasonal amounts of water resources.
[FIGURE 5 OMITTED]
[FIGURE 6 OMITTED]
Lithuanian Power Plant is the largest national thermal power plant
(Fig. 6). The facilities of the power plant include the main building,
which contains the energy equipment, hydrotechnical buildings, as well
as auxiliary buildings and structures. The auxiliary buildings host the
chemical water treatment plant, the electrolysis plant, the compressor room, laboratories, the physical plant, as well as administrative and
household premises. Three chimneys (one of 150 metres and the other two
of 250 metres) of the power plant are also important structures. They
ensure pull and dissipate emitted gasses. The power plant mainly runs on
boiler oil and natural gas. When Ignalina Nuclear Power Plant will be
closed in 2010, this power plant will be the main electricity producer
and supplier in Lithuania.
[FIGURE 7 OMITTED]
The geothermal Power Plant was constructed in 2004 (Fig. 7) seeking
to continue industrial geothermal research, as well as to develop
technologies for tapping of underground resources and make integrated
use of them in economic activities. Facilities of the company include:
the building of Klaipeda geothermal power plant used for activities and
the first geothermal bores made in Lithuania, in 1989. Geothermal bores
reach geothermal water of a temperature of 40[degrees]C, which is then
heated up to 70[degrees]C and supplied to centralised urban networks.
Operating efficiency of the power plant depends on the price of natural
gas and on fixed prices for procurement of the produced heat. Despite
complicated operating conditions, activities of the geothermal power
plant are considered very promising and its development is actively
promoted.
This research has an aim to measure the utility level and adjusted
market value of Lithuanian energy companies, which use traditional and
alternative energy resources, applying the Decision Support System for
Measurement of Effect of Environment Factors on Value of Energy
Companies developed by the authors. It is difficult to appraise objects,
which are basically different although operate in the same sector.
However, multiple criteria analysis methods are a good choice in order
to analyse and assess objects with rather different parameters.
Quantitative data of the analysed energy objects are shown in Table 4.
4.1. Creation of the criteria system
The research is based on the results obtained through use of the
expert method of criteria assessment. In prepared questionnaires, expert
groups assessed the impact of environment factors on activities of the
selected energy sector objects. Objective results were ensured by
forming expert groups from representatives of different social groups:
specialists of energy companies, managers, CEOs; two expert groups
included residents who own property close to energy objects. A total of
six expert groups took part in the survey. Questionnaires for the expert
evaluation were prepared in such way as to achieve maximum assessment of
indicators within components of the Analysis Model for Environment
Factors. Qualitative criteria which define environment factors of the
analysed objects and quantitative criteria which define the actual data
were selected for measurement of the utility degree and market value of
the objects. The experts used a table to set the values of macro, meso
and microenvironment criteria which affect the value of the four
specified objects. Weights of the criteria are assessed using
conditional measurement units: points between 1 and 10 in this
particular case. The experts gave more points to these criteria which
they consider to have bigger weight, to be more "influential",
and make bigger impact on the end result of valuation. The utility level
and market value of the selected objects were measured based on
qualitative criteria assessed by the experts and quantitative criteria
describing the objects.
First, experts helped to set priorities of all determined criteria,
i.e. the criteria were ranked on a scale between 1 and 29. Reliability
of the research was verified by calculating the degree of opinion
coincidence of expert groups. During the research, each expert group
submitted assessments of the four analysed energy objects. The results
of expert assessment were processed and summarised in the table of
criteria values and weights. The ranking and weights of criteria
determined during expert assessment are provided in Table 5.
4.2. Measuring the utility degree and market value
The priority and weight of variants of the analysed objects depend,
directly and proportionally, on a criteria system which adequately
defines the alternatives, as well as on values and weights of the
criteria. The utility level shows the level of goals achieved by
stakeholder groups. Considering the utility degrees of analysed real
estate alternatives, the value of a specific object/alternative is
measured. The utility degree and market value are measured for each
object using the calculation sequence presented in subchapter 4.2 and
formulas (1) through (12). Although values of criteria which, according
to the value, affect the elements specified in the Analysis Model for
Environment Factors are assessed by experts, this information, however,
can change due to the impact of stakeholder groups who may influence
decisions by their goals and ability to achieve them. Therefore, expert
groups, which represent certain stakeholders, assessed possible degree
of stakeholder influence as well.
The main window of the Decision Support System for Measurement of
Effect of Environment Factors on Value of Energy Companies (ESIAPVN-DS)
is shown in Fig. 8. ESIAPVN-DS system work on address of internet
network http://193.219.145.33/elektra/default.aspx.
[FIGURE 8 OMITTED]
Table 6 presents the calculations for the utility degree and market
value of the analysed energy objects, i.e. Kruonis Pumped-storage
Hydroelectric Power Plant, Kaunas Hydroelectric Power Plant, Lithuanian
Power Plant and Geothermal Power Plant, which were performed using the
Decision Support System for Measurement of Effect of Environment Factors
on Value of Energy Companies developed in Vilnius Gediminas Technical
University.
Having assessed the determined values of indicators, it can be
noted that experts attributed the biggest weight to the following
indicators: the experience of top managers, staff qualification, EU
regulation of activities, cooperation with science establishments and
environmental regulations. The social role of energy companies also
carries a considerable weight. In future, during the improvement of
studies of environment factors, this indicator can be analysed more
thoroughly dividing it into more specific components. Using the unique
decision support system for the measurement of the utility degree and
market value of objects, which was developed in Vilnius Gediminas
Technical University, it is possible to measure the ratio of ranks of
each selected criterion, that clearly defines each object by showing its
differences compared to the best alternative.
It is continued by measurement of indicator weights and making a
normalised decisionmaking matrix. Obviously, Kaunas Hydroelectric Power
Plant has the highest utility degree and the first priority. This result
was determined by the use of renewable sources, high profit margin,
environmental aspect (not affected by external pollution costs),
favourable public opinion on activities and low production costs. The
Geothermal Power Plant comes as the second alternative which has a
considerable potential of renewable energy sources independent of
seasonal variations, favourable public opinion and opinion of
stakeholder institutions about activities, high social responsibility
level and innovativeness.
When the best alternative is set, then the adjusted object's
market value is calculated using the formulas (10) through (12). The
company's replacement cost, which differs from the market value, is
taken as the initial value. Energy objects usually have higher
replacement cost than the obtained income capitalisation value or
possible sales price. Using the intelligent software for the processing
of multiple criteria analysis results, we obtained the number of
approximations and the adjusted market value of objects. Tables 7-10
show the results of market value measurement of energy objects.
5. Recommendations
The problem is how to define an efficient energy sector enterprises
life cycle when a lot of various interested parties are involved, the
alternative project versions come to hundreds thousand and the
efficiency changes with the alterations in the micro, meso and macro
environment conditions and the constituent parts of the process in
question. Moreover, the realization of some objectives seems more
rational from the economic and ecological perspectives thought from the
other perspectives they have various significance. Therefore, it is
considered that the efficiency of energy sector enterprises life cycle
depends on the rationality of its stages as well as on the ability to
satisfy the needs of the interested parties and the rational character
of the micro, meso and macro environment conditions.
Formalized presentation of the multiple criteria analysis (see
Table 11) shows how changes in the micro, meso and macroenvironment and
the extent to which the goals pursued by various interested parties are
satisfied cause corresponding changes in the value and utility degree of
energy sector enterprises. With this in mind, it is possible to solve
the problem of optimisation concerning satisfaction of the needs at
reasonable expenditures. This requires the analysis of energy sector
enterprises versions allowing to find an optimal combination of
different interested parties goals pursued, micro-, meso- and
macroenvironment conditions and finances available.
[TABLE 7 OMITTED]
[TABLE 8 OMITTED]
[TABLE 9 OMITTED]
[TABLE 10 OMITTED]
Table 11 provides extensive information about the quantitative
effect of environment factors on value of energy companies. Last columns
of the matrix provided in Table 11 give information about possibilities
to increase the value of energy companies. Let us take production costs
(cnt/kwh) of the Lithuanian Power Plant as an example. This cell of the
matrix provided in Table 11 shows that:
-- Production cost of Lithuanian Power Plant is 31 cnt/kwh. It is
the highest production cost among the compared alternatives (22 cnt/kwh
for Kruonis HAE, 9 cnt/kwh for Kaunas HE and 12 cnt/kwh for Geothermal
Power Plant).
-- Calculations show that theoretically this production cost may be
improved by 70.97%.
-- Improvement of production cost by 70.97% in Lithuanian Power
Plant means a 17.24% increase of its market value.
Let us take another example from legal regulation of activities of
the Geothermal Power Plant (Table 6):
-- Experts gave 18 points to legal regulation of activities of the
Geothermal Power Plant (the lowest result among all analysed power
plants).
-- Calculations show that the legal regulation of activities may be
improved by about 22%.
-- Improvement of 22% in legal regulation of activities of the
Geothermal Power Plant means a 0.18% increase of its market value.
Table 12 provides information about criteria that have the greatest
influence on the ranking of energy companies.
6. Conclusions
1. The developed Analysis Model for Environment Factors of
electricity companies, which incorporates information and intelligent
technology, allows analysing corporate environment and value affecting
factors, as well as to assess environment efficiency, the related
stakeholder groups which want to achieve their goals, and the entire
external macro, meso and microenviroment which that the environment and
the stakeholder groups. The authors supplemented the Analysis Model for
Environment Factors of electricity companies by the criterion of
corporate social responsibility as a promising factor which affects
company's value.
2. Assessment of special-purpose property of infrastructure
companies must include the analysis of factors which define compliance
with environmental requirements and norms, as well as the measurement of
weights of such factors and their influence on operating efficiency and,
respectively, on the value.
3. When solving tasks related to the valuation of special-purpose
property of energy sector, an effective instrument can be a value
analysis model which matches corporate economic goals, corporate
environmental responsibility from social, ecologic and economic
perspective, as well as influence of environment factors on corporate
property.
4. Valuation methods which are deemed traditional fail to account
for the entire set of value affecting criteria. These methods set value
of an energy company as a sum of separate complexes of facilities (using
the replacement cost approach) or the transformed value of forecast cash
flows based on subjective assumptions (using the income capitalisation
or other economic methods). Thorough assessment of environment factors
helps to improve objectiveness of assumptions; it also facilitates
assessment of the utility level of the analysed objects and,
respectively, adjustment of the value.
5. Multiple criteria analysis methods, which incorporate the use of
intelligent support systems, enable a broader perspective, through the
use of simple instruments, on the market value measurement process of
objects operating in various branches; it also facilitates the
assessment of a larger variety of value affecting factors and their
linking with constantly changing environment factors thus monitoring
changes of value. The developed Decision Support System for Measurement
of Effect of Environment Factors on Value of Energy Companies
(ESIAPVN-DS) facilitates the measurement of the utility level and market
value of the analysed objects, as well as the analysis of factors which
may affect the value, at the same time searching for solutions to
eliminate negative effect of factors or to identify the strengths.
