Provisional Measure No. 1,300/2025 Alters the Electric Sector and Impacts Solar Energy in Brazil, Reducing Economic Benefits for Consumers and Small Producers.

Those who invested in solar energy believing in savings may face new costs after the sanction of Provisional Measure No. 1,300/2025, as reported this Thursday, 02. The legislation reformulates part of the rules of the electric sector, and experts already point out that the impact will be direct on the wallets of consumers and small energy generators.

Until now, compensation for generated solar energy was full. That is, the consumer received full credit for the energy they injected into the grid. With the new guidelines, the National Electric Energy Agency (ANEEL) is now allowed to include costs in the tariff that go beyond consumption, which may reduce the economic viability of residential and commercial solar systems.

Expanded Access to the Free Energy Market

Despite the pressure on solar energy, the PM also brought measures seen as advancements. Among them, the expansion of access to the free energy market, allowing more consumers to choose their suppliers. Another point was the inclusion of exemptions in the electricity bill for low-income families, a measure considered essential for mitigating inequalities in energy access.

Higher Tariffs Pressure Companies and Large Consumers

Another sensitive point is the end of the discount on the so-called “wire tariff,” which benefited companies that used renewable sources, such as solar energy itself. With the removal of this benefit, large consumers will incur additional costs, putting pressure on sectors that had been betting on clean energies to reduce expenses and emissions.

ANEEL will play a central role in the regulation of the new rules, while the Electric Energy Trading Chamber (CCEE) will be responsible for managing the dynamics of the contracts. Distributors will need to adapt to the contractual and accounting separation, as well as implement technological innovations to meet the new market design.

This set of changes reinforces the complexity of the moment for the electric sector and, especially, for solar energy, which is no longer seen merely as synonymous with savings and now requires increased attention to regulatory costs.

A giant printer called the “Ferrari” of concrete has landed in Latin America and can already build a 120-square-meter house in just 48 hours, making the traditional construction site look like something from the last century.

Brazil will harvest a record crop of up to 357 million tons of grains, but it does not have the capacity to store a large part of it. The storage deficit has reached the highest level in history and is equivalent to almost the entire production of Argentina.

Four times faster than the Concorde, capable of taking passengers from New York to London in less than an hour at Mach 5.5, and with an engine that switches from turbojet to ramjet mid-flight at Mach 3.5, the Hermeus Quarterhorse went from paper to its first flight in just 19 months.

Under nearly 2 kilometers of ice in Antarctica, scientists have discovered an ancient landscape sculpted by rivers up to 60 million years ago, the size of Wales, preserved as a time capsule that could help predict the advance of ice towards the ocean.

She started by collecting oyster shells from restaurants and today she has already accumulated more than 10 tons to restore reefs, recover coastal habitats, and demonstrate how a common waste can become a tool for ocean conservation.

Bricklayers off the scaffolding? New system uses autonomous drones to position bricks and apply adhesive in the air, creating walls with two flying robots working as a team.

For the economist José Kobori, the USA gained a trump card to “blackmail” Brazil and undermine China’s influence by classifying the PCC and Comando Vermelho as terrorists, increasing the power to pressure companies, banks, and even Pix.

BYD Atto 2 DM-i flex prepares to debut in Brazil with a plug-in hybrid engine, national assembly in Camaçari, competitive pricing, and targets Creta and T-Cross in a battle that promises to heat up the compact SUV market.

Processors can become 1,000 times faster with a new device that uses light pulses, operates in 40 picoseconds, and reduces the heat that stalls data centers.

Noise in the sky frightened residents: NASA confirms that a meteor exploded over New England with a force equivalent to 230 tons of TNT

The paycheck that seemed impossible: São José employee receives R$ 7.94 after legal strike, while deductions by the City Hall affect over a thousand employees and become a target of inquiry in the City Council.

Solar energy covered rooftops and deserts, but now it’s preparing a mountain of old glass: up to 78 million tons of photovoltaic panels could become waste by 2050 as the world races to recycle the shiny skin of the energy transition.
