Asian Development Bank and Tata Power Delhi Distribution Limited Enter into Partnership for Enhanced Power Distribution in Delhi

Strategic Insights -

Asian Development Bank (ADB) and Tata Power Delhi Distribution Limited (TPDDL) have entered into an agreement to enhance Delhi's power distribution through grid enhancements and the 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. The partnership aims to improve the reliability and resilience of Delhi's power distribution system, enabling the integration of intermittent solar and wind energy resources.

Key Takeaways:

  • ADB and TPDDL will subscribe to non-convertible debentures for Rs 1.5 billion ($18.2 million) to finance grid enhancements and the integration of a pilot BESS.
  • The pilot BESS, with a capacity of 10 MWh, is South Asia's first grid-scale energy storage project at the distribution transformer level.
  • The BESS 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.
  • ADB's Director General for Private Sector Operations, Suzanne Gaboury, noted that the partnership will contribute to a more disaster-resilient power distribution system for Delhi.
  • Tata Power's CEO & Managing Director, Dr. Praveer Sinha, emphasized the importance of the BESS in building a resilient grid and paving the way for a future-ready power distribution network.
  • India's Ministry of Power has targeted a battery storage capacity of 4% of total electricity consumption by 2030.
  • ADB's financing will provide proof of concept and lessons learned by TPDDL to implement a planned additional 50 MWh of BESS capacity.

Statistics:

  • The total battery energy storage capacity required in India by 2030 is 182 gigawatt hours.
  • The planned additional 50 MWh of BESS capacity will support TPDDL's goal of integrating clean energy into the power supply mix.
  • TPDDL's operational area spans 510 square kilometres with customers across industrial, commercial, household, and agricultural segments.
  • The partnership aims to improve the reliability and resilience of Delhi's power distribution system, supporting a customer base of 1.9 million connections.
