Análise do impacto dos projetos de eficiência energética implantados com recursos do PEE em instituições de ensino público: estudo de caso da UTFPR - campus Curitiba

Abstract

The expansion of photovoltaic generation and the implementation of energy efficiency (EE) measures are established as fundamental strategies in the face of tariff volatility and the need for decarbonization of the national electricity matrix. Within Higher Education Institutions (IES), high energy consumption motivated the National Electric Energy Agency (ANEEL) to promote EE and Distributed Generation (GD) actions, notably through Priority Call No. 001/2016. This dissertation analyzes the impact of EE projects implemented with resources from the Energy Efficiency Program (PEE) at the Federal University of Technology Paraná (UTFPR), Curitiba Campus, under the Public Call for Projects (CPP) notices from Copel No. 001/2017 and No. 001/2018. The total amount made available was R$ 3,838,534.19, with a completion rate of 74.03%. The interventions included the modernization of the lighting system and the installation of photovoltaic systems (SFV) under ideal conditions with a total capacity of 326.88 kWp. The methodology was based on the Measurement and Verification (M&V) guidelines of the International Performance Measurement and Verification Protocol (IPMVP), adopting Option C (whole-facility analysis via utility bills). The performance of the PVS was evaluated through merit indices such as yield (YF), capacity factor (FC), and performance ratio (PR). From the financial perspective of society, estimates indicate that the project implementation generated savings of approximately R$ 3,102,020.61 for the HEI. Invoice analysis between 2019 and 2025 revealed a 22.31% reduction in consumption and 15.93% in costs following the implementation of Energy Efficiency Actions (AEE). Even in the face of significant tariff increases, which reached 26.28% during peak hours, the measures adopted were able to absorb the adjustments and generate real savings. The results reveal that, although the targets for savings and peak demand reduction are relevant, the absence of a systematic operational verification process, including continuous monitoring of generation and merit indices, compromised the full realization of benefits. Therefore, mandatory operational verification, validated by independent audits, is essential to ensure the persistence of savings and the longevity of assets funded by the PEE.
