The volume of registrations in battery auctions proves strong market interest, he says. ABSOLAR

The volume of projects registered for the LRCAP-BESS (Capacity Reserve Auctions in the form of Storage), scheduled for December 2nd and 4th, 2026, demonstrates the high market interest in energy storage systems.

According to data from EPE (Energy Research Company), the The competitions received entries from over 6 businesses., which together have 296,9 GW of installed capacity, reinforcing the sector's expectation regarding the first exclusive battery contract in the country, which has been awaited for more than three years.

The assessment is from ABSOLAR (Brazilian Photovoltaic Solar Energy Association). According to the organization, the number of registered projects demonstrates that the Brazilian market already has the conditions to expand investments in storage systems.

“This is a strategic technology to expand the operational flexibility of the SIN (National Interconnected System), increase energy security, and accelerate the integration of renewable sources, such as solar and wind power,” points out Rodrigo Sauaia, CEO of [company name]. ABSOLAR.

The next step will be the technical qualification of the projects, and the process will be responsible for verifying whether the ventures meet the requirements to participate in the auctions.

"This step is crucial to ensure compliance with the minimum requirements for participation in auctions, with only projects that are suitable and adequate to the needs of the Brazilian electrical system being eligible," Sauaia adds.

For Sérgio Jacobsen, Vice President of Storage at ABSOLARThe first battery auctions represent more than just a one-off capacity purchase.

"This represents the effective opening of a new market in the country, capable of boosting investments, stimulating technological innovation, strengthening the value chain, and generating skilled jobs and new business opportunities within the national territory," he comments.

In view of this scenario, the ABSOLAR He stated that he advocates for storage auctions to be integrated into an annual calendar, ensuring predictability for investors, manufacturers, and developers.

"Predictability is an essential factor in scaling the market, attracting manufacturers, investors and developers, increasing competition and reducing the costs and prices of technology over time," says Jacobsen.

Regulatory adjustments

Despite the interest shown by the market, the association believes that there are still regulatory and legal aspects that need to be improved to ensure the success of the first auctions.

"There are concerns in the sector regarding provisions outlined in the tender, the evolution of which will be fundamental to ensuring greater legal certainty, competitiveness, and attractiveness to investments. This measure depends on the public consultation to be conducted by..." ANEEL (National Electric Energy Agency), over the next few weeks,” said Sauaia.

Another point considered a priority by the entity is the revision of Law No. 15.269/2025. Under the current rule, power generators are responsible for paying the ERCAP (Capacity Reserve Contracting Charge), a cost related to contracting battery storage systems.

For ABSOLARThis charge creates a distortion in the market and discourages new investments. "The currently applicable rule imposes exclusively on the generation segment the costs associated with contracting capacity through battery storage systems, creating a regulatory asymmetry incompatible with the principle of technological neutrality and introducing legal uncertainty into the bidding process," he explains.
