India awards long-duration energy storage contracts for 1,344MW pumped hydro, utility-scale flow battery

Curated by Shubham · TechCapsules · Jul 21, 2026

AI-summarised brief · reviewed before publication

The Solar Energy Corporation of India (SECI) awarded 1,344 MW of pumped‑hydro capacity through a reverse‑auction to Tata Power (324 MW), Greenko (720 MW) and Torrent Energy Storage Solutions (300 MW), under tariff‑based competitive bidding and long‑term PPAs. The tender, launched in late 2025, was revised to target up to 1,500 MW of 12‑hour storage, reflecting the nation’s push for long‑duration energy storage (LDES). Simultaneously, Indian startup Delectrik secured a contract to supply a 100 MWh vanadium redox flow battery for the 30 GW Gujarat Hybrid Renewable Energy Park, marking the country’s first large‑scale flow‑battery deployment. SECI’s contracts follow a broader policy drive that includes streamlined clearances, transmission charge waivers and an estimated need for 74 GW of storage by 2032, rising to 90 GW of pumped hydro by 2047.

💡 Why It Matters

· The dual awards accelerate India’s transition to grid‑scale, multi‑hour storage, directly addressing the capacity gap needed to balance its rapidly expanding renewable fleet.

South Australia’s Lunio Energy brings 20MWh grid-scale battery storage system online

South Australian developer Lunio Energy has commissioned its first grid‑scale battery energy storage system (BESS) at Strathalbyn, a 5 MW/20 MWh facility located about 60 km south of Adelaide, and begun trading in the National Electricity Market. The battery stores electricity when market prices are low and discharges when prices rise, with future participation planned in frequency control ancillary services (FCAS). Optimisation and market bidding are handled by OptiGrid’s AI‑driven OptiBidder platform, which also manages over 170 MW of Australian BESS assets. Lunio Energy, part of the broader Lunio Group, selected OptiGrid after its strong capture‑rate performance. The system already operated during June’s price‑cap events, demonstrating the revenue potential of precise state‑of‑charge management in South Australia’s volatile market.

💡 Precise AI optimisation turns South Australia’s price volatility into measurable profit, proving that sophisticated forecasting can unlock value from short‑duration price spikes.

European Energy reaches financial close on 80MWh Mokoan solar-plus-storage site in Australia

European Energy secured AU$110 million (US$77 million) of non‑recourse financing from Deutsche Bank to refinance its 58 MWp Mokoan Solar Farm and fund a co‑located 40 MW/80 MWh battery energy storage system (BESS) in Victoria, Australia. The solar plant, operating since June 2025 on 94 ha near Wangaratta, produces about 113 GWh annually and was selected under the Australian government’s Capacity Investment Scheme, which provides long‑term revenue support. The financing package includes a term loan, hedging and ancillary facilities, and marks the second Australian financial close for European Energy within three weeks, following the Winton North solar‑plus‑storage project. Deutsche Bank highlighted the deal as evidence of rising institutional appetite for integrated renewable assets, adding to its support of over 12 GW of Australian renewables since 2019.

💡 The combined solar‑storage model offers investors a single, flexible asset that can deliver both steady generation and grid‑balancing services, accelerating the shift toward reliable, contract‑backed renewable power.

Hyundai Motor Group Expands Korea’s Hydrogen Ecosystem with First Group-Operated Waste-To-Hydrogen Facility

Hyundai Motor Group launched HTWO ENERGY Cheongju, its first integrated waste‑to‑hydrogen (W2H) production and refueling hub, converting biogas from local wastewater sludge into about 500 kg of hydrogen daily. The Cheongju site, backed by the Ministry of Climate, Energy and Environment, is positioned as an inland hydrogen logistics center and part of South Korea’s Hydrogen City Creation Project. The output can fuel roughly 100 new NEXO fuel‑cell vehicles or 30 hydrogen buses, and the facility includes a Hydrogen Academy for public education. Hyundai plans to expand capacity to two metric tons per day by 2030, using the model to roll out similar W2H ecosystems in Indonesia, Hong Kong and other markets, aiming for localized, self‑sufficient hydrogen supply chains.

💡 By turning municipal waste into transport‑grade hydrogen on‑site, Hyundai cuts reliance on imported coastal hydrogen and creates a replicable blueprint for carbon‑neutral mobility in cities worldwide.

Power, water needs test South Korea’s push to build AI chip hub…

South Korea aims to establish a new semiconductor hub in its southwest region by 2030, central to President Lee Jae Myung’s strategy to distribute AI chip industry benefits beyond Seoul. The Honam complex, estimated at 800 trillion won, faces significant local opposition due to massive power and water requirements. Four planned fabrication plants could consume 70% to 80% of the current annual electricity in Gwangju and Jeolla provinces. Residents oppose new transmission lines, nuclear reactors, and dam modifications, citing lack of consultation and infrastructure flaws. While the energy ministry claims existing generation capacity is sufficient, experts warn that without accelerated infrastructure expansion, operating at full capacity will be difficult. Previous projects in Yongin faced similar delays due to resource disputes. The government plans to work with local authorities to build infrastructure and improve public acceptance, potentially considering new nuclear options to meet the complex’s substantial energy demands.

💡 Local resistance to infrastructure expansion threatens to derail South Korea’s strategic decentralization of its semiconductor industry. This conflict exposes the critical tension between national economic ambitions and regional community rights regarding resource allocation.

Romania ROUNDUP: Aukera, ENEVO Group and Kraftfeld Energy, and PPC Renewables advance…

Aukera secured a €48.5 million loan from the International Finance Corporation to finish the second phase of its Gura Ialomitei battery‑energy‑storage system (BESS) in Romania. The funding will add 100 MW/200 MWh, bringing the project to 250 MW/500 MWh – the country’s largest operational BESS and one of the biggest in Central and Eastern Europe, with commercial operation slated for early 2027. Earlier, Aukera completed phase one (150 MW/300 MWh) in June 2026 after a US$68 million debt facility. Meanwhile, ENEVO Group and Kraftfeld Energy signed a turnkey EPC contract to build a 110 MW/220 MWh BESS in Drăgănești‑Olt, with construction starting Q3 2026 and commissioning expected early 2027. These projects reflect Romania’s rapid emergence as a leading BESS market in Europe, driven by falling battery costs, supportive regulations and recovery‑fund allocations.

💡 By anchoring megawatt‑scale storage at the heart of its growing solar fleet, Romania is poised to become a strategic balancing hub for the continent’s renewable grid, accelerating Europe’s transition to reliable, low‑carbon power.

Return and Engie, EnBW and Zelestra agree long-term BESS tolls in Spain,…

Return and Engie have sealed a 10‑year tolling agreement for three battery‑energy‑storage system (BESS) projects in Spain’s Basque region, totalling 55 MW of power and 220 MWh of capacity, with commercial operation slated for the end of 2027. Under the full‑toll model, Return will develop, own and operate the assets while Engie pays a fixed fee and assumes all market revenue, leveraging its optimisation platform across Spain’s wholesale and ancillary‑services markets. In Italy, EnBW has secured long‑term toll rights to 300 MW of capacity from Zelestra’s 500 MW/2,000 MWh BESS in Emilia‑Romagna, with construction beginning in 2027 and commissioning expected in 2028. The deal covers 60 % of the project’s capacity and follows earlier negotiations that hinted at up to 2 GWh of storage.

💡 The contracts lock in revenue streams for emerging European storage assets, accelerating grid‑stability solutions in markets that have recently tightened storage incentives after the 2025 Iberian blackout.
