The Solar Energy Corporation of India (SECI) has issued a tender for two 1.5MW(AC) solar power projects with battery energy storage systems of 0.75MW / 2.5MWh each at two locations in the Indian state of Jammu and Kashmir.
The tender, which has been issued on behalf of construction agency Military Engineer Services (MES), is for design, engineering, supply, construction, installation, testing, and commissioning of the two projects at Tangtse and Durbuk in Leh district (Ladakh). It also includes 10 years of operations and maintenance (O&M) services.
MES provides rear line engineering support to the Armed Forces. The Indian army is prominent in Ladakh due to the mountain region's proximity with the Chinese and Pakistan borders. Temperature at the project locations range from -30°C to 30°C and altitude is around 3,000 metres.
The battery storage system will be interconnected with the local distribution network and designed for maximum flexibility with regard to voltages, frequency, phase imbalance and protection requirements, according to the tender document.
The whole capacity of the tender will be awarded to a single contractor and the deadline for bid submissions is 23 August 2018.
India recently moved a step closer to having its first lithium-ion cell manufacturing facility with an agreement between local firm Raasi Group and two research institutions. Meanwhile, any kind of energy storage technology will be permitted in hybrid wind and solar projects under the government's recently released new hybrid policy.
