India Wind Policy Weekly: 18 September 2026

CERC relaxes the six-month REC application deadline for a Karnataka wind developer, and CTUIL sets a route for projects with connectivity to add battery storage.

Covering 12 to 18 September 2026. Two items: a certificate deadline relaxed after utility delays, and a route to add storage behind existing connectivity. Every item is checked against the issuing authority's own document.

1. CERC relaxes REC deadline for a Karnataka wind developer after utility delays

CERC · 14 September 2026 (Petition 234/MP/2023)

Tadas Wind Energy Private Limited developed 100 MW of wind projects in Haveri district, Karnataka in 2012 under eight MoUs with HESCOM under the REC scheme. It sought Renewable Energy Certificates (RECs) for July 2022, but the National Load Despatch Centre (NLDC) rejected the application by email on 13 March 2023, because the REC rules require an application within six months of the corresponding generation.

Tadas said HESCOM delayed issuing the B-Form and joint meter readings during a dispute over expiry of the MoUs. HESCOM issued the B-Form on 31 January 2023 and the State Load Despatch Centre issued the Energy Injection Report on 18 February 2023. NLDC told CERC it had no objection. CERC held the delay was procedural and would not prejudice any stakeholder, relaxed the time limit under Regulation 18 of the REC Regulations, 2022, and directed NLDC to issue RECs for July 2022 after due verification that the project meets all conditions and the documents are complete.

Why it matters for wind: REC projects can still obtain certificates when a distribution company's delays push the application past six months, but only by petitioning CERC. The relaxation is case-specific, so developers should still track B-Form and meter-reading timelines closely.

2. CTUIL advisory covers adding battery storage to projects already granted connectivity

CTUIL · 14 September 2026

The Central Transmission Utility of India Limited (CTUIL) issued an advisory on enhancement of Battery Energy Storage System (BESS) capacity for projects that have already been granted connectivity. It provides an implementation mechanism for projects seeking to increase storage capacity, measured in MWh, while staying linked to the connectivity already granted to the project.

The MNRE digest notes it is particularly relevant for renewable projects using BESS as a flexibility and grid-integration resource, where BESS capacity or duration may be increased after the original connectivity approval. This summary follows the digest; the advisory's detailed conditions are not reproduced there.

Why it matters for wind: Wind and hybrid projects that want to add battery hours after connectivity is granted now have a defined route tied to their existing connectivity. The conditions in the advisory itself should be checked before planning on it.
