<h1>Renewable developer wins 600 MW/1,200 MWh standalone BESS contract including design, build, commissioning and five-year O&M</h1> A renewable energy developer was awarded a 600 MW / 1,200 MWh battery energy storage system contract by a government solar procurement agency, marking one of the agency's largest standalone BESS awards. The contract covers design, engineering, civil works, installation, testing, commissioning and five years of operation and maintenance for a grid-connected facility in Andhra Pradesh tied to an interstate transmission substation. Legally significant issues likely include performance and commissioning milestones, grid-interconnection and dispatch obligations, warranty and O&M liabilities, compliance with procurement and local content requirements, and implications for the developer's market position and national grid reliability goals.
