ADB, Tata Power sign deal to enhance Delhi's power distribution system

Asian Development Bank (ADB) and Tata Power Delhi Distribution Limited (TPDDL), the distribution arm of The Tata Power Company Limited (Tata Power), entered into an agreement to subscribe to non-convertible debentures for 1.5 billion Indian Rupees (equivalent to $18.2 million) to enhance Delhi’s power distribution through grid enhancements, and a $2 million grant to partially finance the purchase and integration of a pilot Battery Energy Storage System (BESS).

The senior secured financing will be used to commission a new 66/11-kilovolt grid, augment and expand transformers, substations, feeder lines, and switching stations, install smart meters, and replace obsolete electrical equipment and meters, as per the regulatory filing.

In the regulatory filing, the 10-megawatt-hour (MWh) BESS is South Asia’s first grid-scaled energy storage project at the distribution transformer level. It will enable electricity to be stored and delivered on demand, reducing grid instability, and providing the flexibility to integrate intermittent solar and wind energy resources. 

The grant to finance the BESS is provided by Goldman Sachs and Bloomberg Philanthropies’ Climate Innovation and Development Fund (CIDF) and administered by ADB.

“The battery energy storage system plays a crucial role in building a resilient grid and paves the way for a future-ready power distribution network. We thank ADB for administering this grant for the integration of the pilot BESS with TPDDL’s network. This will enable us in ensuring high-quality power supply for consumers and help integrate clean energy into the power supply mix,” said by Dr. Praveer Sinha, CEO & Managing Director, Tata Power.

“Power distribution is a crucial link in the electricity supply chain, and at times one of the most vulnerable. Mainstreaming a battery energy storage system at the distribution transformer level will better integrate renewable energy sources and contribute to a more disaster-resilient power distribution system for Delhi,” said ADB’s Director General for Private Sector Operations Suzanne Gaboury. “As Asia’s Climate Bank, ADB supports India’s climate goals through innovative technologies and the catalyzing of private capital to finance green projects.”
