Financing distributed generation projects

This work aims to propose a regulatory framework for the creation of energy communities in Ecuador by referencing successful international experiences and adapting them to the national context. Through a detailed analysis of the current legal framework regarding distributed generation and renewable energy, the study identifies existing opportunities and limitations for implementing such communities. The research applied a qualitative and documentary methodology, including a comprehensive literature review and expert interviews with academics, officials from public and private energy generation and transmission companies. Additionally, successful energy community models from countries such as Spain, Germany, and the USA were examined. The major findings include the lack of specific regulations in Ecuador, which hinders the development of decentralized energy systems. Based on this, a normative proposal was developed to promote the use of renewable energy and citizen participation in energy production and management. This study contributes to Ecuador’s energy transition by encouraging decentralization and sustainability, and it offers concrete strategies for the technical, economic, and social feasibility of energy communities. The findings aim to support policy-making and investment in renewable energy and distributed generation projects.

The expansion of the electric power system by large central generators linked to end consumers through extensive transmission lines, at an ever-increasing voltage, points toward a complementarity and an ever-increasing participation of Distributed Generation (DG). In this manner, there is a need to define criteria and technical criteria for the assessment of DG projects that ensure returns on investment. This article proposes a modeling of technical criteria through multiattribute value functions to analyze the technical benefits stemming from DG projects. To accomplish this goal, a multicriteria methodology will be applied which allows for the simultaneous treatment of the diverse technical aspects necessary in the planning and decision-making processes, as well as the implementation of the Utility Theory to define a behavior that is averse, willing or neutral to a determined criterion.

The article explores the economic challenges of developing distributed electricity generation in Ukraine amid the energy transition in 2025. The key barriers hindering the sector’s growth are analyzed, including outdated infrastructure, high implementation costs, difficulties in microgrid integration, and limited access to financing. The study identifies essential measures needed to stimulate distributed generation, such as regulatory reforms, the creation of financial incentives, and investment attraction. Special attention is given to the potential use of the stock market as a capital-raising tool for the sector’s development. The study examines the prospects of issuing green bonds, conducting IPOs of energy companies, and establishing investment funds that could provide financing for distributed generation projects. The research findings confirm that a comprehensive approach, incorporating government support, private initiatives, and market mechanisms, will facilitate the effective integration of distributed generation into Ukraine’s energy system. This, in turn, will contribute to enhancing the country’s energy security and economic resilience.

A multi-criteria decision-making framework for distributed generation projects investment considering the risk of electricity market trading

Electric energy consumption has been a significant part in budgets of universities, so that the applying of distributed generation projects may be an alternative to reduce financial costs related. The objective of this paper was to analyze the usage of photovoltaic solar energy in Brazilian universities. For this, a case study of financial feasibility and mitigation of greenhouse effect gases were conducted due to the application from a photovoltaic system at the Federal University of Espirito Santo (UFES), Campus Sao Mateus. Moreover, a survey of the conditions on photovoltaic energy usage at Federal universities in Brazil took place. In this case study, it was clear that the solar energy project is economically viable with a 4-year discounted payback, and an internal rate of return of 13.5%. Other research has indicated the financial attractiveness of the use of this technology in higher education institutions in the country. Still in this case study, the solar energy project demonstrated that it would avoid the emanation of 327,916 kgCO2/year. It was canvassed that, of 69 federal universities, 35% already have photovoltaic systems installed, 13% are installing as of now and 3% of them have approved budget to acquire the necessary equipment. Lastly, an increase of the usage of solar energy at Brazilian universities is expected in the next years due to the urge of costs reduction and the inevitable growth of environment sustainability at these institutions.
