- Mon 23:54BESS bet - The Solar Energy Industries Association (SEIA)'s Energy Storage Energy Market Outlook for Q1 2026 found US battery energy stationary storage (BESS) installations increased 29% YoY in 2025, surpassing 57 GWh/28 GW. SEIA said the utility-scale market underpinned growth with just under 50 GWh/16 GW installed, with California, Texas, and Arizona accounting for 74% of installed capacity. US BESS deployments are set to increase to 70 GWh/35 GW in 2026, with the utility-scale market accounting for 62.4 GWh/20.2 GW. By 2030, the market is set to exceed annual installations of 110 GWh/47 GW. By 2030, cumulative installed utility-scale BESS is set to reach just under 500 GWh.
- Mon 23:53SCOTUS nod - The US Supreme Court (SCOTUS) agreed on Monday to hear a bid by ExxonMobil and Suncor Energy to dismiss a lawsuit from Boulder County, Colorado that seeks to hold the energy companies liable for the effects of climate change, Reuters reported. SCOTUS took up an appeal by the companies of a lower court's ruling that let the litigation move forward. The appeal is backed by the Trump administration, and the lawsuit is is one of dozens of climate-related lawsuits filed by US jurisdictions against companies that extract, produce, distribute or sell fossil fuels. In a client note, consultancy Washington DC-based ClearView Energy Partners said Monday's decision is the first instance in which a climate liability case has reached SCOTUS for review based on energy companies’ argument that federal preemption applies in state tort litigation. The consultancy added that the court could hear oral argument early in its next term, beginning in October, with a decision following by year-end or early 2027, while a ruling would influence similar suits.

Developers have sought briefings with lawyers holding security clearances to understand and potentially mitigate the concerns, according to court filings. Wind supporters said they aim to build backing for the projects by focusing on energy affordability, an issue that has gained traction among voters, as a counter to the administration's opposition.
