ESS Tech to add 8.5 GWh of U.S.-made sodium‑ion batteries to its portfolio
ESS Tech is complementing its iron flow storage offering, which is engeeneered for the 8–24 hour long-duration segment, with sodium-ion battery products aimed at short and medium-duration applications.
More than 67 GW storage, 14 GW solar seek interconnection in PJM’s reopened queue
Grid operator PJM has reopened its standard interconnection process to new generation projects, after closing the standard process to new applicants in 2022 to completely clear its backlog.
Clean power captures 91% of new U.S. grid capacity as 2025 installations hit 50 GW
The U.S. clean energy sector set a blistering pace in 2025, with utility-scale solar, wind, and energy storage accounting for 91% of all new power capacity added to the domestic grid.
Republican legislators seek to restore clean energy tax credits
Four Republican representatives introduced The American Energy Dominance Act to help lower costs, strengthen domestic supply chains, drive long-term investment in energy infrastructure, and support good-paying union jobs.
Solar and storage to lead 86 GW capacity surge in 2026
New federal data shows solar and battery assets will comprise nearly 80% of all new utility-scale power additions planned for the U.S. electric grid this year.
The battery cost disconnect
For years, the battery energy storage (BESS) story has followed a familiar script: costs fall, deployment accelerates, economics improve. Even when cell costs rose and system prices briefly flattened during the 2021-22 lithium price spike, the narrative largely held. Paola Perez Peña, senior principal analyst at S&P Global Energy, examines why the latest jump in lithium prices has only had limited impacts on overall BESS costs so far.
For solar advocacy work, it’s “AI or die,” says leader of Puerto Rico solar group
Artificial intelligence came through at a crunch time for SESA-PR President PJ Wilson. The veteran solar advocate makes the case in an interview for solar and storage policy advocates to make good use of AI resources.
Prepare for launch: Solar powers the $600 billion space industry
Human activities in space have been solar powered for more than 70 years. Now, as the space industry accelerates, new opportunities are emerging for specialized solar manufacturers, writes Jake Veloza of Eternal Sun Wavelabs. The extreme and unforgiving conditions of space demand a high level of performance and durability, and accurate testing methods will be needed to get these new solutions off the ground.
Tesla energy storage deployments down 15% on ‘clumpy’ first quarter
After peaking at over 14 GWh and accounting for 15% of Tesla’s revenue in the fourth quarter of 2025, energy storage saw a seasonal decline to 8.8 GWh accounting for 10.8% of the company’s revenue.
Navigating the new NERC requirements for vendor remote access
As of April 1, 2026, the enforcement of NERC Reliability Standard CIP-003-9 mandates that renewable energy operators transition from informal vendor management to a rigorous, evidence-based cybersecurity framework for all low-impact assets.
