Large-scale solar developers in Brazil have surrendered authorizations for over 40 GW of capacity and $26.3 billion in lost investment due to curtailment rates of around 25% and uncertainty over compensation. New curtailment rules offer greater certainty, but a recovery in investment will depend on other factors. The pace of authorization cancellations has accelerated, with the pipeline of projects falling from 60 GW in January to 40 GW in the first half of the year.

The French government plans to ease grid connection rules for solar-plus-storage projects up to 25 MW, with measures aimed at reducing energy costs and improving demand flexibility. The initiatives, set to be implemented by 2026, include making subsidies for heat pumps conditional on smart-control capabilities and enabling smart-control functions in new EV charging installations. The government also plans to introduce flexibility requirements for industrial energy metering systems and encourage the integration of Linky smart meters with residential energy management systems.

Lectric offers up to $762 e-bike bundle savings starting from $999, along with a Worx 40V 20-inch Cordless Electric Snow Thrower for $395 and a Jackery HomePower 1000 V2 1,024Wh Portable Power Station for $549.

Solar inverters can operate at temperatures up to 115°F, but unventilated attics or south-facing stucco walls can exceed this limit, causing the inverter to slow down or shut down to protect itself. Inverters "fold back" to reduce power output when temperatures rise, and the heat management system usually quits first, with the inverter's control module often being the last component to fail. This can lead to a prolonged shutdown or reduced performance in extreme heat conditions.

Best Buy has started testing battery-powered vehicles at its California distribution sites, including electric yard switchers, as part of its efforts to reduce emissions. The retailer plans to gauge the potential for future deployment of these vehicles across its entire supply chain. The pilot program aims to curb emissions at Best Buy's distribution sites.

Temporary microgrids provide a blueprint for a flexible, resilient power grid to meet surge demand, addressing physical bottlenecks at the traditional grid edge. The microgrid industry is growing and faces challenges in managing demand and infrastructure limitations. Microgrids can help create a more resilient power grid.

Qcells will offer domestic-frame options for its Q.TRON AC and Q.PEAK DUO AC residential solar panels, featuring aluminum frames made in Tennessee. The frames will help meet minimum domestic content requirements for third-party owned solar projects in the United States. This is part of Qcells' effort to increase domestic manufacturing capabilities in the country.

Slovakia's newest nuclear power unit, Mochovce 4, has been connected to the grid and is now supplying its first electricity.

Reliability officials emphasize the importance of proper cyber hygiene as AI becomes more prevalent in cybercrime, citing it as the best defense against emerging risks from agentic AI, which are becoming a reality. Maintaining good cyber hygiene is the key to preventing cyber threats, regardless of AI's growing role. Effective cyber hygiene practices are crucial in safeguarding energy infrastructure and preventing potential cyber attacks.

Stakeholders respond to Bonneville Power Administration's proposal to connect large loads to the grid faster, with the Public Power Council emphasizing that money shouldn't be the only determinant of who gets transmission. The BPA's proposal aims to create an open season process for connecting large loads. The Public Power Council expresses cautious optimism about the proposal.
