The tender is for design, engineering, supply, construction, erection, testing, commissioning including five of O&M services of the plants at the town of Kaza, which is the subdivisional headquarters of the remote Spiti Valley in the Lahaul and Spiti district.
The battery will be located at Rangreek, near Rong Tong Hydro Power Station, 12,000 feet in altitude, facing annual temperature ranges of -40°C to 30°C. The area can see snow of up to six feet in winter months.
The tender noted that the battery “shall be designed for maximum flexibility with regard to site-specific voltages, frequency, phase imbalance, and protection requirements”.
Any battery technology can be used as long it is deemed suitable for the location’s climatic conditions. The batteries will also be containerised.
There was good news for energy storage in India recently with the reduction of the Goods and Service Tax (GST) on lithium-ion batteries.
SECI also recently 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 state of Jammu and Kashmir.
