Pylontech held a mass-production ceremony for its 588Ah and 601Ah large-capacity ESS cells at its Hefei base on Sep 21. Cumulative output has exceeded 100MWh, and the cells are already used in its new PyOcean 6.25MWh and 8MWh utility-scale systems, which have won orders and shipped. The 601Ah cell reaches 425.8Wh/L volumetric energy density, over 12,000 cycles and 96.5% energy efficiency. The Hefei line is 100% automated in core processes, with full lifecycle traceability for every cell.

Envision Energy announced on September 21 that it had successfully energized a 25 MW/125 MWh LFP battery system at OCP Green Energy’s Benguerir mining site in Morocco. The system is undergoing testing before commercial operation and will shift surplus daytime solar power to peak-demand hours. It is designed to reduce the site’s peak-hour electricity bill by approximately 25%.
