Brazil’s solar association, Absolar, has proposed an 8 GW large-scale energy storage target by 2030 as part of a broader set of priorities for President Luiz Inácio Lula da Silva’s re-elected government. Its agenda also calls for recurring battery auctions, greater use of curtailed renewable electricity and solar-plus-storage access for 3 million consumer units; these are proposals, not confirmed government commitments.
Brazil’s solar association has proposed installing 8 GW of large-scale energy storage by 2030, alongside annual battery auctions and measures to use electricity currently curtailed from renewable generators. The Brazilian Photovoltaic Solar Energy Association, or Absolar, presented the proposals as three commitments for President Luiz Inácio Lula da Silva’s re-elected government; the proposals are not yet government policy.
Absolar’s plan for 2027 to 2030 is organized around three pillars: Bateria Brasil, Energia que Emprega and Sol para Todos. Bateria Brasil calls for annual, technology-neutral capacity auctions, the 8 GW storage goal and lower battery taxes, which the association says should be brought in line with taxes on renewable energy sources. It also supports pairing batteries with new and existing rooftop solar systems.
The association wants the battery capacity reserve auctions scheduled for December 2 and 4 to become the start of a recurring procurement program. It is also calling for clarity on how those auctions will be funded, implementation of the Special Incentive Regime for Infrastructure Development for storage projects, and a dedicated legal framework. Law No. 15,269/2025 provides for the infrastructure incentive regime, according to the source report.
Absolar says battery taxes can reach 84.8%, more than twice the rate applied to renewable energy sources. The association also calls for compensation for renewable projects whose output is curtailed, saying this is provided for under law. The proposals combine measures on storage investment with a remedy for generators that cannot deliver all the electricity they could produce.
Storage Could Absorb Curtailed Power
The proposed target responds to a growing gap between renewable generation potential and the electricity the grid can take. Absolar reported that solar and wind curtailment reached 17.2% of potential output in the first quarter of 2026. That figure is the association’s reported measure for that period; the material does not provide a longer-term comparison or a breakdown by technology.
Battery storage could help move some electricity from times when generation exceeds grid demand to periods when it can be used. Absolar argues that attracting data centers, energy-intensive industries, green hydrogen projects and electric mobility could also create domestic demand for power now being curtailed. These are proposed routes to absorb surplus generation, not confirmed investments or evidence that storage alone would resolve grid constraints.
The third pillar, Sol para Todos, proposes expanding electricity access to 3 million consumer units through solar-plus-storage systems. Absolar also wants storage-based alternatives to diesel generators in isolated power systems, which it says could reduce charges including the Fuel Consumption Account and the Energy Development Account. The scale, funding and delivery schedule for these measures are not detailed in the reported proposal.

Three Pillars for Energy Policy
Energia que Emprega focuses on increasing domestic use of renewable electricity that is currently curtailed. Alongside attracting new large consumers, Absolar calls for transmission planning and enabling 18 GW of new solar power plants. The association identifies transmission and distribution capacity as potential bottlenecks for major consumers considering projects in Brazil.
One possible source of demand is the country’s planned data-center tax regime, Redata, established by Law No. 15,504/2026. The regime includes conditions related to renewable or low-emission electricity, but the executive branch still needs to issue implementing regulations, according to the report. Absolar says new data-center development needs to be matched with energy planning and network investment.
The proposals also arrive as Brazil prepares to expand access to its free electricity market. Under Law No. 15,269/2025 and a decree issued in August 2026, commercial and industrial low-voltage consumers are scheduled to enter from November 2027, with residential consumers following from November 2028. Absolar is seeking clear rules, consumer protections, public information and competitive conditions for renewable power in that market.
““Restoring predictability to the electricity sector” will require compensating projects whose generation has been curtailed and ensuring the successful execution of the December battery auctions as the first step in an annual program.”
— Bárbara Rubim, chair of Absolar’s board
Government Response Remains Unknown
The reported proposals do not establish whether the federal government will adopt the 8 GW target, set a schedule for annual auctions or change battery taxation. No government response, approved funding plan or implementation timetable is included in the source material. The December auctions are scheduled, but their results and whether they will lead to recurring procurement remain unknown.
Other open questions include how storage projects would qualify for the infrastructure incentive, what legal framework Absolar is seeking, and how compensation for curtailed renewable generation would be implemented. The reported 17.2% curtailment figure covers solar and wind potential output in the first quarter of 2026; further figures, including the amount of electricity that storage could economically capture, are not provided.
The source also does not specify how the proposed access for 3 million consumer units would be funded or phased, or which locations would receive systems first. Redata’s implementing regulations, grid investments and future appointments to the electricity regulator ANEEL are additional developments that may shape the proposals but are not settled in the report.
December Auctions Set Near-Term Test
The next scheduled milestone is the battery capacity reserve auctions on December 2 and 4, 2026. Their design, funding and outcomes will help show whether the auctions can support storage deployment and whether the government will consider Absolar’s request to make procurement annual.
Absolar says it will continue engaging with federal and state governments, Congress, state legislatures and regulators. Further developments to watch include decisions on storage incentives and rules, compensation for curtailed generation, Redata implementation and the planned opening of the free market to low-voltage consumers. The association’s proposals remain advocacy priorities until public authorities take specific action.
Key Questions
What storage target has Absolar proposed?
Absolar proposes 8 GW of large-scale energy storage by 2030. It has presented the target to the re-elected federal government as part of a broader energy-policy agenda.
Has Brazil adopted the 8 GW target?
The source report describes it as an Absolar proposal. It does not report that the government has adopted the target or committed to a deployment schedule.
Why is the association calling for more storage?
Absolar points to renewable generation being curtailed when it cannot be used by the grid. It reported that solar and wind curtailment reached 17.2% of potential output in the first quarter of 2026.
What happens with the battery auctions?
Capacity reserve auctions for battery energy storage systems are scheduled for December 2 and 4, 2026. Absolar wants them to begin an annual procurement program, but the report does not confirm that the government will establish one.
What else is included in Absolar’s plan?
The plan calls for using more curtailed renewable electricity, enabling 18 GW of new solar power plants, and expanding solar-plus-storage access to 3 million consumer units. It also proposes replacing diesel generators in isolated systems with storage-based solutions.
