Utility Scale Storage

Every additional EV, wind turbine, transmission line, or storage system intensifies pressure on supply chains that are already concentrated and geopolitically sensitive. Competing solely on mining is neither sufficient nor sustainable.

Global solar growth is flattening in major markets as oversupply from China and India drives prices down and shifts competition from sheer volume to execution, policy alignment, and system integration. Across the U.S., Europe, and China, energy storage is becoming essential for project viability, making PV-plus-storage and strong EPC partnerships the new basis for winning projects in 2026 and beyond.

Uniper has signed the agreement to offtake up to 500,000 tons per year from AM Green’s green ammonia projects. The first shipment is expected to happen as early as 2028 from AM Green Ammonia’s first 1 million ton per annum (MTPA) under construction plant in Kakinada, Andhra Pradesh.

Rajasthan Solar Park Development Co. Ltd (RSDCL) has launched a tender inviting proposals to set up 2,450 MW of state transmission utility (STU)-connected solar PV power projects with 1,600 MW/6,400 MWh battery energy storage systems at the Pugal Solar Park in Bikaner district of Rajasthan. The projects will be developed on a build-own-operate (BOO) basis.

By 2050, sodium-ion batteries with fast learning rates could deliver storage at 11–14 €/MWh – cheaper than lithium-ion at 16–22 €/MWh – while also offering higher energy-to-power ratios and high cycle durability, a new research finds.

The Solar Energy Corp. of India’s (SECI) tender for 1.2 GW of interstate transmission system (ISTS)-connected solar projects, integrated with 600 MW/3,600 MWh of energy storage systems (ESS), has discovered a tariff of INR 3.12/kWh.

Power Mech Projects Ltd has won a contract to set up a 250 MW/1,000 MWh standalone battery energy storage system (BESS) at Goaltore, Paschim Medinipur, West Bengal, on a build-own-operate (BOO) basis, with a greenshoe option of 250 MW/1,000 MWh at Durgapur Project Ltd (DPL) campus. The project, awarded by West Bengal State Electricity Distribution Co. Ltd (WBSEDCL), comes with a 100% off-take guarantee.

India is estimated to have added a record 40 GW of solar capacity in CY 2025, supported by strong utility-scale execution and a surge in rooftop installations. Energy storage tendering also picked up pace.

Startups are rewriting the narrative of India’s environmental challenge by building a bridge between air quality restoration and renewable energy expansion—a synergy that promises to fundamentally reshape how India confronts both crises simultaneously.

Hartek Power has secured an engineering, procurement and construction (EPC) contract worth approximately INR 353.77 crore for a 280 MW AC (410 MWp DC) solar PV power plant integrated with an 80 MW/320 MWh battery energy storage system (BESS) in Karnataka.
