Karnataka Tops Power Sellers in Green Day Ahead Market in Q1 2022

Karnataka was the top seller of power in the Green Day Ahead Market (GDAM) in the first quarter (Q1) of 2022, accounting for 58.9% of the total power sold in the quarter, according to Mercom India Research’s newly released report Mercom India Solar Open Access Market Report Q2 2022.   

Karnataka was followed by Madhya Pradesh (6.5%), Adani Hybrid Energy Jaisalmer Three (Solar) with 6%, Adani Hybrid Energy Jaisalmer (One) with 5.9%, and ReNew Solar Energy Jharkhand (Three) with 3.7%.

The top five entities accounted for 81.1% of the total power sold in GDAM.

Karnataka was also the top power seller in the GDAM space in Q4 2021.

In October 2021, GDAM was introduced on the power exchanges. This segment provides participants the opportunity to purchase electricity on a day-ahead basis.

Some of the prominent features of GDAM/GDAC:

  • A single window for bidding per the existing timeline of 10 AM to 12 noon.
  • Market clearing is sequential; first, Green Day Ahead Contract (GDAC) will be cleared, followed by the Day Ahead Contract (DAC), considering the uncleared bids of GDAC, if any.
  • In the event of real-time transmission constraints, curtailment of transmission would be per the provisions of the Grid Code.
  • Buyers will be given the flexibility to choose the renewable purchase obligation (RPO) they wish to fulfill from the power procured from GDAC.
  • GDAC will be restricted to those renewable energy generators not registered under the renewable energy certificate (REC) mechanism. The sale of power by such generators in DAC would not be eligible for RECs.
  • The waiver of ISTS charges and losses would be governed as per the provision of the sharing regulations.
