Covering 30 May to 5 June 2026. Connectivity took centre stage, in two central orders and a draft state framework. Every item is checked against the issuing authority's own document.
1. CERC sets aside a connectivity revocation and orders CTUIL to clear pending final grants in 30 days
CERC · 31 May 2026 (Petition 1015/MP/2025)
Datta Power Infra sought relief for its 162 MW ISTS-connected wind-solar hybrid projects awarded by SJVN (120 MW solar, 42 MW wind), connecting at Dhule, with the firm start date of connectivity and SCOD both 30 June 2026. CTUIL revoked connectivity on 11 February 2026 after the developer missed the 31 December 2025 financial closure deadline. CERC held that a tentative SCOD of February 2028, quoted in an SJVN e-mail against a PPA not yet signed, cannot support an extension. But CTUIL was itself required to issue the final grant by 15 August 2025 and issued it only on 29 December 2025, about 4.5 months late, stating the last date for financial closure as 30 December 2025. CERC said this delay cannot be justified and that CTUIL should be more prudent, while imposing no penalty for now.
CERC directed CTUIL to process all pending final grants within 30 days of the order where applicants have submitted the requisite connectivity bank guarantees and augmentation planning poses no issue, and to file a compliance report. Using its relaxation powers under the GNA Regulations, CERC set aside the revocation and gave the developer 30 days to furnish its financial closure document. The following 60 days attract a delay penalty of 5% of the bank guarantee amount, and non-submission beyond 90 days is to be dealt with as revocation and encashment.
Why it matters for wind: Late final grants can consume a developer's financial closure window, and this order puts a clock on CTUIL's own approvals. Revoked connectivity can be restored, but at the cost of a delay penalty on the guarantees.

2. KERC releases draft intra-state connectivity and GNA regulations for comment
KERC · 4 June 2026
The draft KERC (Connectivity and General Network Access to the Intra-State Transmission and State Distribution System) Regulations, 2026, follow the Forum of Regulators' model. Objections and suggestions are open for 30 days, and the rules are proposed to take effect from 1 October 2026. Wind or energy storage system (ESS) stations of 5 MW and above may seek connectivity at intra-state transmission level, either for non-solar hour access on identified substations or for full-day access; below 5 MW, connectivity is at distribution level. Solar and solar-hybrid stations get solar-hour access.
A co-located hybrid may apply for connectivity equal to its highest renewable source capacity, its ESS capacity, or up to the combined capacity, with the SLDC able to curtail injection above the connectivity granted. The transmission-level application fee is Rs 1.0 lakh for renewable sources, and connectivity bank guarantees come in three parts, starting with Conn-BG1 of Rs 10 lakh, plus Conn-BG2 for augmentation and Conn-BG3 of Rs 1 lakh/MW for an existing grantee in some cases.
Why it matters for wind: The draft decides how wind projects in Karnataka would get non-solar hour or full-day access on the intra-state network, and how co-located hybrids and storage would size their connectivity and guarantees. Developers have 30 days to comment.

3. CERC allows 30 more days of infirm injection for 27 MW of a Tamil Nadu wind project
CERC · 2 June 2026 (Petition 178/MP/2026)
JSW Renew Energy has commissioned 162 MW of the 189 MW phase of a 270 MW wind project in Tamil Nadu, but 27 MW (10 turbines of 2.7 MW) missed commercial operation after an imported sub-controller failed during power plant controller testing on 27 September 2025. SRLDC had approved first time charging on 17 September 2025 and permitted infirm injection for 45 days, to 1 November 2025; beyond a maximum of 135 days only CERC can extend. The developer approached SRLDC only on 13 March 2026 and filed its petition 67 days late.
CERC said the developer should have approached the regional load despatch centre 10 days before 1 November 2025, but condoned the delay given the project's advanced stage of commissioning. It allowed infirm power injection for a further 30 days from the order under Regulation 19(3) of the Grid Code, with the commissioning events acknowledged only for this purpose.
Why it matters for wind: A single failed component can hold up commissioning of an otherwise complete wind plant. CERC will extend infirm injection for advanced projects, but developers must alert the load despatch centre in time.

4. Welspun withdraws connectivity for a 250 MW hybrid project; CTUIL told to process the exit
CERC · 3 June 2026 (Petition 815/MP/2025)
Welspun Narmada had sought extension of financial closure for its 250 MW wind-solar hybrid project at Bidar, Karnataka, with in-principle connectivity granted on 22 July 2024. Since the developer had already asked to withdraw the connectivity application, CERC held that the financial closure issue no longer survives.
CERC directed CTUIL to process the withdrawal under Regulation 3.7.3 of the GNA Regulations, tell the developer within 10 days the amount to be deposited, and allow cash in lieu of encashing the bank guarantees. The developer has 10 days to pay, failing which CTUIL encashes the guarantees.
Why it matters for wind: The order confirms the exit path when a developer gives up connectivity: a defined deposit, a 10-day timetable, and an option to settle in cash rather than lose the guarantees outright.
