GEAPP invites interested parties to respond to the Expression of Interest for a ’20 MW/40MWH Grid-Connected BESS project’ in New Delhi, India.

GEAPP is inviting Expression of Interest (EOI) from interested parties as part of a market sounding exercise for a distribution-level Grid Scale Battery Energy Storage System (BESS) pilot project.

It is expected the 20MW/40MWh (2 hours) BESS will be installed at a 33/11kV Grid substation of BSES Rajdhani Power Limited (BRPL). The BESS is expected to be designed to provide 2 cycles of daily operations for a period of 12 years to tap into benefits such as energy arbitrage, peak shifting, ramping support to integrate Variable Renewable Energy (VRE) generation, ancillary services, deferral of network/line upgrades, etc. This pilot for deployment of BESS at scale could support future development of the technology and sector adoption, which will support grid stability and reliability, while enabling increased penetration of renewable energy. There is potential for reduction of carbon emissions by enabling adoption of renewable generation, and support for reliable, clean energy supply.

In this regard, GEAPP is seeking responses and submission of information from interested parties in one or both of the following areas:

  1. System Integrators (SIs) for Engineering, Procurement, and Construction (EPC) as well as operations & maintenance (O&M) of the BESS
  2. Commercial Investors for ownership (potentially partial) of the BESS. System Integrators may also express interest as commercial investors

Deloitte has been appointed as the Project Management Unit for the BESS project.
