Abstract
[Abstract]: Modern portfolio theory (MPT) stands as a widely accepted methodology to meet the challenges associated with the
definition of energy planning for a particular territory or region. Energy planning is thus framed as an investment selection
problem. MPT is characterized by having a wider capacity and conceptual richness than the other previously used
methodologies, such as the individual least cost alternative. The portfolio approach is based on solving for an objective
function that seeks to minimize either the cost or the risk of the portfolio, subject to different constraints, considering that
real electricity generation assets can be defined in terms of cost or return and economic risk for each alternative
technology. The relevant portfolios are the result of solving the optimization model, to determine the efficient cost-risk
frontier. The work presented here consists of an exhaustive review of the literature in relation to the application of MPT
methodology to the field of energy planning and electricity production. A new classification is proposed from a financial
perspective of the selection of investments from the preceding studies. It delves deeper into the explanation of the limits to
the methodology and into the concept of risk, which is key from both a financial and an energy perspective. The main
methodological contributions found in the literature are examined that are aimed at improving the capacity of the model
and adjusting it to the reality of the electricity market, Finally, conclusions are provided from the works analyzed in terms of
renewable technologies and the policy implications derived from them. In most studies, a preference has been shown for the
inclusion of renewable technologies in the efficient portfolios. However, in order to implement the decision to increase the
share of renewable technologies, greater flexibility in the interconnection capacity between states and in storage capacity is
needed
