Brazil’s ISA CTEEP Opens Battery Energy Storage System

Dec. 1, 2022
The project benefits more than 2 million people in Brazil.

São Paulo, Brazil’s transmission grid operator Companhia de Transmissão de Energia Elétrica Paulista (ISA CTEEP) installed and energized an energy storage system, connected to the power grid, which will enable greater integration of renewable energy.

This technology makes an important contribution to the energy transition, as it allows for greater integration of renewable energy sources into the Brazilian system, according to an announcement by ISA CTEEP. The project benefits more than 2 million people in Brazil.

The lithium ion batteries were installed in an area of about 5,000 square meters, which is the equivalent of half a soccer field. It has 30 MW of power, which will guarantee the demand of more than 2 million people and avoid the emission of 1.194 tons of CO2 in two years of operation, as it replaces the use of diesel generators.

The batteries will be activated at times of peak consumption as a backup to the power grid, ensuring additional power for up to two hours. This will prevent the interruption of the energy supply due to excess demand during this period, thus guaranteeing greater security and reliability in the provision of the service.

ANEEL’s baseline investment in this project was more than $27 million and the Annual Allowed Revenue (RAP) is about $5 million. Both values refer to June 2021, according to ANEEL Authorizing Resolution.

ISA CTEEP operates in 17 Brazilian states and employs more than 1,400 people. The grid operator’s power network transmits about 30% of the electricity used in the country, including 92% of the electricity used in São Paulo.
