During Brazil Windpower, CGN Brasil Energia and Goldwind announced a pilot energy storage project with batteries at the Tanque Novo Wind Complex in Bahia. The initiative aims to reduce losses and enhance the efficiency of wind power generation in the country.
The energy storage sector in Brazil has just gained a decisive boost. CGN Brasil Energia and Goldwind signed a strategic agreement during Brazil Windpower 2025 to develop a battery pilot project (BESS) at the Tanque Novo Wind Complex, located in Bahia.
The event, considered the largest in Latin America in the wind energy segment, took place from October 28 to 30 in São Paulo (SP) and brought together leaders from the energy sector to discuss innovative and sustainable solutions. The cooperation contract signed between the two companies promises to pave the way for a new phase of efficiency in the generation and use of clean energy in the country.
How the Energy Storage System Will Operate
With a power of 745 kW and capacity of 1.49 MWh, the system will be installed in one of the turbines at the Brazilian wind farm. The main objective of the project is to reduce generation losses caused by electrical grid limitations, technically known as curtailment.

In practice, the system will allow storing surplus energy generated during periods of restriction and releasing it later, adhering to contractual supply limits. This strategy ensures greater stability and efficiency for the complex, avoiding waste and optimizing the use of wind energy produced.
According to the companies, battery storage represents an essential technological advancement for the future of the electricity sector, as it allows balancing generation and demand, even in scenarios of high intermittency of renewable sources.
Energy Storage: The New Pillar of the Energy Transition
CGN Brasil Energia emphasizes that the Tanque Novo BESS project reinforces its commitment to innovation and sustainable development.
“Energy storage is one of the pillars of the energy transition and an essential tool for the full utilization of Brazil’s renewable potential. This project demonstrates CGN’s commitment to innovation and sustainable development in the Brazilian electricity sector,” stated Isabela Barata, Business Development Manager at CGN Brasil Energia.
The Tanque Novo BESS project is considered an experimental milestone in the application of storage systems in wind ventures in the country. It is expected to generate technical and regulatory results that will serve as a basis for the expansion of this technology on a large scale in the national territory.
Goldwind Invests in Innovation and System Reliability
For Goldwind, the partnership with CGN Brasil Energia symbolizes an important step towards the consolidation of smart clean energy solutions in Brazil.
“It is a great opportunity to establish this partnership with CGN Brasil Energia in a pioneering project that combines cutting-edge technology and operational experience. The 745 kW / 1.49 MWh battery system was developed to provide reliability, security, and flexibility, directly contributing to the reduction of curtailment and maximizing the delivery of clean energy,” highlighted Liang Xuan, General Manager of Goldwind Brazil.
With this initiative, the country reinforces its position as a reference in innovation in the energy sector, enhancing the integration between wind energy and energy storage technologies. This combination is seen by experts as the next step in the global energy transition, allowing for greater stability and predictability in the operation of electrical systems.
Smart Integration and Gains for the National Interconnected System
The project is part of the strategy of both companies to evaluate, in a real operational environment, solutions capable of increasing the flexibility and stability of the National Interconnected System (SIN).
By investing in energy storage systems, the Brazilian electric sector prepares for a more balanced and sustainable future, where the use of batteries will become an essential component of energy infrastructure.
In addition to mitigating losses and optimizing production, the model will allow for greater integration between renewable sources, making the system more resilient to climatic variations and the growth of distributed generation.
The Tanque Novo BESS project thus not only reinforces the importance of technological cooperation among global companies but also symbolizes a new chapter in the history of clean energy in Brazil, combining innovation, sustainability, and efficiency in a single initiative.
