摘要:The role of the private sector is essential in providing energy access to all by 2030. However, private investors often face the decision problem of deciding where to implement off-grid projects. This selection process can be considered a multifactorial task because it requires accounting not only for local conditions, technical constraints, and economic-financial feasibility but also for socio-cultural dynamics and environmental consequences. In this paper, we implemented a multi-criteria decision-making (MCDM) method based on the Measuring Attractiveness by a Categorical Based Evaluation Technique (MACBETH) to assist in the selection of the most suitable location to implement off-grid solar PV projects in South America. Following a participatory process with the input of a decision-maker representing the private sector, we combined 13 criteria, within 5 dimensions, to evaluate the performance of three potential sites, namely Bolivia, Peru and Colombia. Based on an overall score associated with each alternative, we grouped them into three categories: highly sustainable, sustainable, and unsustainable. As a result, Colombia represents the highest sustainable option for a potential private investor. This methodology provides guidance not only to investors but also to local utility companies and policymakers assessing off-grid locations with electricity access deficits, in developing countries.
