Diseño de un sistema fotovoltaico para el área administrativa de las gerencias de la Corporación Nacional de Electricidad CNEL EP Matriz 2025.

Abstract

This paper describes the design of a photovoltaic system for the administrative area of the management of the National Electricity Corporation CNEL EP MATRIZ 2025, a strategic entity in the Ecuadorian electricity sector. Ecuador recorded a record demand of 4,682 GWh in May 2023, where the public-commercial sector accounts for 26% of national consumption. CNEL EP faces critical vulnerabilities, putting pressure on its energy matrix. CNEL EP, a strategic player in electricity distribution, has two key vulnerabilities: 70% dependence on hydro/thermoelectric plants, exposed to droughts and fuel volatility. Annual consumption of 150 MWh in its corporate offices, with high operating costs and avoidable CO₂ emissions. Methodological components: Accurate sizing through historical consumption analysis and simulation in PVsyst Professional. Invoicing model adapted to the current tariff specifications. Multi-criteria evaluation: Return on Investment (ROI), carbon footprint reduction and regulatory alignment. Economic: 25-40% reduction in energy costs (based on INER pilot cases). Operational: Real-time monitoring of power quality and savings. Environmental: Mitigation of CO₂ emissions by replacing fossil sources. Strategic: Compliance with national energy transition policies. Scalable model to other CNEL EP locations The project positions CNEL EP as a benchmark for sustainability in the Ecuadorian public sector, closing the gap between national policies and their operational application. Its implementation: Reduces dependence on the central grid, contributing to national energy security. It generates an estimated ROI in 6 years (validated by experiences such as EPMAPS-Quito). It catalyzes the adoption of renewable energies in state institutions, aligning with the Sustainable Development Goals (SDGs). This proposed initiative synthesizes technical feasibility, economic profitability and environmental responsibility, transforming an operating liability (underutilized ceilings) into a strategic asset for CNEL EP and the national electricity system. Its demonstrative success will boost distributed generation in Ecuador, accelerating the goal of 90% clean energy by 2030.
