The announcement of the company’s latest module power electronics project came alongside Q1 2026 earnings that showed a 20.6% decrease in year-over-year revenue numbers amid a steep decline in domestic demand.

In a week marked by the largest sodium-ion battery order to date, widely seen as a watershed moment for the technology’s commercialization at scale, one of Europe’s emerging players, Spain’s Bihar Batteries, is strengthening the outlook for European-made sodium-ion batteries.

Some of the consequences of the blackout include a 589% increase in installed BESS capacity in Spain between April 2025 and April 2026, the introduction of renewable participation in voltage control, a greater role for gas in the generation mix, and continued progress on interconnections.

Solar Energy Corporation of India has invited proposals to set up interstate transmission system (ISTS)-connected renewable energy projects for assured peak power supply of 1,500 MWh (500 MW for three hours) under a contract-for-difference (CfD) mechanism.

Sungrow has released a mining microgrid power solutions white paper in partnership with TÜV Rheinland and the China Electrotechnical Society covering application scenarios from 2.5 MW up to more than 100 MW.

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.

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.

CATL has completed a roughly $5 billion share sale in Hong Kong on Tuesday. Meanwhile, Chinese inverter and battery manufacturing giant Sungrow is making a second attempt at an IPO after its initial listing bid, launched in October 2025, lapsed.
