CERC Proposes Auctioning Connectivity To Ease Grid Congestion
The recommendations are part of a consultation paper examining large volumes of renewable energy (RE) capacity for which developers have secured Connectivity under General Network Access (GNA) Regulations by submitting LoAs issued by renewable energy implementing agencies (REIAs), but have yet to sign PPAs.
CERC said there is an urgent need to free up Connectivity granted via the LoA route where PPA or power sale agreement (PSA) signing has been delayed. Stakeholders have been asked to submit responses by 15 December 2025.
The paper comes as the Ministry of New & Renewable Energy (MNRE) undertakes a comprehensive review of 43.9 gigawatts (GW) of RE projects stuck due to poor Discom interest in PSAs. As of June 2025, Connectivity has been granted to 31.802 GW of projects while another 13.541 GW of requests are still pending — a total of 45.343 GW for which PPAs have not been signed.
“This is a very significant quantum of Connectivity, as the corresponding transmission systems are either implemented or under implementation,” the regulator said.
To manage future requests, CERC has suggested that only an auction mechanism be used for granting Connectivity, ensuring firm project commitments by specified deadlines. Alternatively, it proposed removing the LoA route entirely and allowing Connectivity only on the basis of PPAs signed under the Centre’s competitive bidding guidelines — acknowledging that developers typically begin substantive work only after signing a PPA.
CERC has also proposed mechanisms to ensure optimal and timely utilisation of the transmission network. For instance, if a project with LoA-based Connectivity has not secured a PPA within 12 months, developers may substitute the initial LoA with a PPA linked to another LoA, provided the Connectivity start date under the second LoA is at least six months later than the first.
Developers may also choose to surrender Connectivity within one month. In such cases, the Central Transmission Utility of India (CTUIL) will encash Connectivity Bank Guarantee-1 (Conn-BG1) and return Conn-BG2 and Conn-BG3. The developer must continue to pay applicable transmission charges until CTUIL accepts the surrender.
