Assessing the Impact of the National Program for Rational and Efficient Use of Energy on the Design of a Biomass Gasifier Integrated with a Photovoltaic-Wind Energy System Case Study: Silos, Colombia

Abstract

This study evaluates the impact of the public policy known as the Programme for the Rational and Efficient Use of Energy (PROURE) on electricity demand forecasting and the resulting energy matrix for the municipality of Silos, Colombia. The proposed energy matrices are obtained using a multi-objective mixed-integer linear programming (MOMILP) model that simultaneously minimises the net present value (NPV) and total CO₂ emissions. The technologies considered include solar photovoltaic panels and wind turbines integrated with biomass gasifiers, aiming to mitigate the environmental impacts associated with biomass waste while promoting the circular economy. The results indicate that compliance with the strategies established in the PROURE policy effectively reduces electricity demand by approximately 19%. This reduction leads to decreases in system financial costs ranging from 9.79% to 11.65% and reductions in total CO₂ emissions between 32.02% and 36.09%. These findings highlight the importance of implementing the PROURE policy, supported by government economic incentives or the adoption of dynamic tariff schemes in the electricity market, as key mechanisms for promoting a sustainable energy transition and mitigating potential congestion in transmission lines. Furthermore, the proposed methodology provides a robust decision-support tool for stakeholders and policymakers, enabling the assessment of the financial and environmental feasibility of PROURE implementation in energy planning projects across different geographical contexts.
