Tata Power-DDL wins CII Industrial Innovation Award for country’s first grid-scale battery energy storage system

Tata Power Delhi Distribution Limited (Tata Power-DDL) has been recognized in the category of ‘Top 25 Innovative Company’ by CII Industrial Innovation Awards 2020 for the development of South Asia’s largest grid-scale Battery Energy Storage System (BESS), in collaboration with AES and Mitsubishi. …

The 10 MWh battery storage set up in Rohini  is interconnected to a network of 200 MW capacity, which can feed around 2,500 special customers, providing essential services. The stored power can also be used during any breakdown or situations like grid failure. In the BESS, Li-ion (nickel, manganese and cobalt oxide) batteries are used, with the support of Advancion Technology to operate the plant seamlessly. The 10 MWh system is divided, into four cores of 2.5 Mwh capacity and, each core can be operated individually and collectively. After Rohini, a similar facility is coming up in North Delhi’s Rani Bagh and, there are plans to have similar but smaller facilities in every neighbourhood in the future.
