The Joint Committee responsible for assessing Provisional Measure No. 1.304/2025 may hold a public hearing to discuss the role of electricity storage in the modernization of the sector.
The request, presented by Congressman Arnaldo Jardim (Cidadania-SP), highlights the need to debate a specific legal framework and new business models capable of integrating battery technologies into the SIN (National Interconnected System).
The parliamentarian recalled that the The topic reached MP No. 1.304 after being left out of the report of MP No. 1.300/2025, which dealt with structural measures for the electricity sector.
"The report on Provisional Measure No. 1.300/2025 maintained the core proposals proposed by the Executive Branch, particularly regarding the social tariff, but failed to address the various contributions presented, none of which were incorporated. In consultation with the Government and party leaders, it was decided to postpone the analysis of sensitive topics, such as energy storage, data centers, and generation curtailments, until Provisional Measure No. 1.304, so as not to jeopardize the measure's enactment," he stated.

In justifying the request, the representative argues that the public hearing should be broad and plural, bringing together strategic actors, technical experts and institutional representatives.
Furthermore, the parliamentarian highlighted that the storage of electrical energy is crucial to guarantee stability and reliability in the grid, especially with the expansion of intermittent renewable sources such as solar and wind.
“It allows us to balance supply and demand, storing energy during periods of low demand for use during peak consumption, reducing costs and avoiding the cutting of excess energy,” he noted.
According to the congressman, storage serves as a backup in case of failures, contributing to safety and the advancement of a cleaner, decarbonized energy matrix.
However, he highlighted that “the lack of a clear legal and regulatory framework for the sector is one of the main barriers to its expansion in Brazil, hindering investments and the integration of batteries into the SIN (National Integrated System)”.
