- ISA CTEEP is the first ISA company to have a storage project.
- The versatile technology will allow providing different grid services to the National System Operator, in addition to compensating for the intermittency of wind and solar generation, allowing for greater integration of renewable sources into Brazil’s National Interconnected System.
- The project is also part of ISA’s objective to contribute to the decarbonization, decentralization and digitalization of the electricity matrix in Latin America.
Brazil’s National Electric Energy Agency (ANEEL) approved the first large-scale battery energy storage project in the Brazilian transmission system. This is an innovative project of ISA CTEEP, the largest private electric power transmission company in Brazil, which will be installed at the Registro substation (São Paulo state), to supply the southern coast of São Paulo.
The lithium batteries will be installed in an area of approximately 4.000 m², with a size equivalent to about 30 containers, and will have 30 MW of installed power, guaranteeing the maximum demand of the South Coast of the state, of approximately 400 MW, and benefiting about two million people. In addition, the batteries will prevent the emission of 1.194 tons of greenhouse gases in two years of operation of the technology and will generate approximately 400 direct jobs until the system is implemented.
The technology will act at times of peak consumption, as a backup to the power grid, ensuring additional energy for up to two hours, totaling 60 MWh, avoiding the interruption of power supply due to excess demand during this period, thus ensuring greater safety and reliability in the provision of service to society.
“The project is a historic milestone for the electricity sector and will serve as a laboratory for innovation, promoting discussions on how to insert energy storage in batteries, especially for its immediate response capacity and high operational flexibility, necessary for the transmission grid.” It is also a step towards the diversification of our business,” explained Rui Chammas, ISA CTEEP’s CEO.
The investment authorized by the regulator is close to BRL 146 million (USD 26 million) and the works are expected to be delivered in November 2022, to meet summer demand from 2022/2023. The Allowed Annual Revenue for the execution of the project will be approximately BRL 27 million (USD 4,8 million).
The technology also contributes to advances in decarbonization, decentralization and digitalization, as it reduces the costs of system operation and expansion, allows the postponement of the construction of large projects, increases the integration of economic energy sources, and can be reused in other parts of the country that need reinforcement in the electricity system.
ISA CTEEP, in partnership with the University of São Paulo (USP), since 2018, studied the feasibility of applying this solution in power transmission, before submitting the Registro substation project to the transmission system planning bodies and the regulator, being considered the first and only concrete application case.
ISA CTEEP
ISA CTEEP is the largest private electric power transmission company operating in 17 Brazilian states. Through ISA CTEEP, ISA Group is in charge in Brazil of transmitting around 33% of the electric power produced by the National Interconnected System (SIN), 60% of the electric power consumed in the southeast Region, and 94% of the electric power consumed in the state of São Paulo. Its electric power system comprises over 20 thousand kilometers of transmission lines and 140 substations (assets in operation and under construction).
