Shanxi Xiangyuan Source-Grid-Load-Storage Integrated Project Phase I Enters Trial Operation
On August 10, Phase I of Xiangyuan County's source-grid-load-storage integrated project (50 MW PV plus 7 MW/28 MWh lithium battery storage) entered full-capacity commissioning and trial operation. Green power is delivered directly to local industrial park enterprises via a 26 km dedicated line, with annual generation reaching 180 GWh. The storage system responds in milliseconds, providing a new model for resource-based counties to achieve local renewable energy consumption.
Shanxi Huozhou 400 MW/700 MWh Independent Storage Station Invites EPC Bids
In August, the 400 MW/700.4 MWh Huozhou hybrid independent storage station EPC project released tenders with a total investment of RMB 2.13 billion. Located at the site of a former chemical fertilizer plant in Huozhou, the project entered full construction phase on August 5. As the largest independent storage station in Linfen, it will participate in Shanxi's market-based electricity trading and smooth fluctuations from wind and solar generation.
Zambia Commissions First Solar-Hydro Hybrid Plant
On August 13, Zambia's first solar-hydro hybrid power station was commissioned, combining a 27 MWp solar PV facility with the existing 56 MW of hydropower operated by Lunsemfwa Hydro Power Company (LHPC) and supplying power to the national grid. The plant is located in Central Province and is implemented by LHPC, 51% owned by Globeleq. Zambia's power system has historically relied heavily on hydropower, with generation constrained during droughts. The hybrid station diversifies generation sources and improves supply reliability.
Construction Begins on 166 MW Solar Plus 80 MWh Storage Project in Philippines
On August 10, Singapore's Levanta Renewables started construction of a 166 MW PV plant with an 80 MWh battery energy storage system in the Philippines. China Energy Engineering Corporation (CEEC) serves as the EPC contractor for the entire project, covering design, procurement and construction. The project, developed by Levanta's subsidiary Magallanes Solar Energy Corporation, is expected to begin commercial operation in Q2 2027.
Uzbekistan Navoi Integrated Energy Project Completes Reverse Power Transmission
On August 15, the Navoi integrated energy project in Uzbekistan, invested by China Energy Engineering's overseas investment subsidiary, completed reverse power transmission and entered the live commissioning phase. The project involves a total investment of USD 394 million, comprising a 300 MW PV plant and 150 MW/300 MWh storage station, generating 750 GWh annually and cutting CO2 emissions by 1.61 million tonnes. It is Uzbekistan's first large-scale integrated renewable energy project.
Karnataka Tenders 2.5 GW Pumped Storage DPR Studies in India
On August 14, Karnataka Power Corporation (KPCL) invited bids for consultancy services to prepare a detailed project report (DPR) for the 2,500 MW Varahi pumped storage project. India is rapidly advancing pumped hydro development as a key long-duration storage technology to support its ambitious renewable energy targets. The country plans to expand pumped storage capacity from about 5 GW to 100 GW by 2035, and this tender marks another step in accelerating project pipelines across Indian states.
Gujarat Tenders 1 GW/4 GWh Standalone Battery Storage in India
On August 13, Gujarat Urja Vikas Nigam (GUVNL) invited bids to set up 1,000 MW/4,000 MWh of standalone battery energy storage systems (BESS) in the state under its Phase-X procurement. The tender represents one of India's largest standalone storage procurements to date, reflecting the country's accelerating shift toward grid-scale flexibility resources. BESS is playing an increasingly critical role in supporting renewable integration, reducing curtailment and improving grid reliability as India expands solar and wind capacity toward its 500 GW non-fossil fuel target by 2030.
