Delhi’s Power Distribution Grid Enhancements and Battery Energy Storage System

active

This project consists of enhancement of Delhi’s power distribution through grid enhancements, which includes a new 66/11-kilovolt grid, augmentation and expansion of transformers, substations, feeder lines, and switching stations, installation of smart meters, and replacement of obsolete electrical equipment and meters. The project also involves the purchase and integration of a 10 MW pilot battery energy storage system (BESS), which is planned to store electricity and deliver it on demand, reducing grid instability, and providing the flexibility to integrate intermittent solar and wind energy resources. The project company is Tata Power Delhi Distribution Limited (TPDDL), which is sponsored by the Government of NCT of Delhi (49%) and Tata Power Company Limited (51%). In 2002, TPDDL is awarded a 25-year license to distribute and transmit electricity in Delhi’s north and northwest regions. The project is financed by the Asian Development Bank (ADB) in the form of non-convertible debentures for 1.5 billion Indian Rupees (equivalent to $18.2 million), as well as $2 million grant provided by the Goldman Sachs and Bloomberg Philanthropies' Climate Innovation and Development Fund (CIDF). The financial close is achieved on April 10, 2023. https://www.adb.org/news/adb-tata-power-sign-deal-enhance-delhi-s-power-distribution-through-grid-enhancements-and
