Type: Investment · Technology: Storage · Country: Brazil · Announced: 2026-08-26
The National Electric Energy Agency (Aneel) provisionally recognized Pacto Energia Distribuição Paraná's R$29.6 million investment in a battery energy storage system (BESS) within the distributor's Regulatory Remuneration Base. The BESS, with a capacity of 10.16 MW and 20.32 MWh, was deemed a fixed asset in service, with its inclusion to be re-evaluated in future tariff reviews as Aneel defines specific regulatory treatment for energy storage. This investment significantly impacted tariff components, increasing the Remuneration of Capital by 308.5% and the Regulatory Reintegration Quota by 224.3%. The BESS now represents 49.66% of Pacto Energia's total Fixed Assets in Service, contributing to an average tariff adjustment of 18.33% for consumers. The increase in costs due to the BESS incorporation was partially absorbed by the Energy Development Account (CDE) due to a tariff limit linked to the adjacent concessionaire, Copel-Distribuição.
