Covering 23 to 29 May 2026. A draft on deviation charges leads a week with two market rulings and a transmission report. Every item is checked against the issuing authority's own document.
1. CERC proposes at-par deviation charges for WS sellers in draft DSM amendment
CERC · 26 May 2026
CERC has issued the draft Central Electricity Regulatory Commission (Deviation Settlement Mechanism and Related Matters) (Third Amendment) Regulations, 2026, with comments due by 26 June 2026 and the draft set to come into force on 1 July 2026. A new clause provides that deviation charges for a WS Seller are to be treated at par with General Sellers in two cases: projects under the bidding route with tendering or bid submission dates on or after 1 January 2027, and other projects with date of commercial operation on or after 1 January 2029. CERC's March order on the value of X had directed staff to propose this treatment for projects bid on or after 1 April 2026; the draft moves that cut-off to 1 January 2027 (see the 3 April edition).
The draft also replaces the time-block Area Clearing Price with the daily weighted average Area Clearing Price of the Integrated-Day Ahead Market segments of all power exchanges for the day when computing deviation charges. Infirm power injected by a standalone energy storage system from first synchronisation to completion of its trial run would be paid at the normal rate of charges for deviations, capped at Rs 2.00/kWh.
Why it matters for wind: General-seller treatment links deviation charges to frequency and market prices rather than a percentage tolerance band, which raises the cost of forecasting error for wind. The cut-off dates decide which projects keep the wind and solar treatment, so bids from 2027 should price in tighter forecasting, aggregation or storage. Comments are due by 26 June 2026.

2. CERC approves source-wise Green Contracts at IEX, with wind as a separate category
CERC · 25 May 2026 (Petition 338/MP/2025)
CERC has approved Indian Energy Exchange's revision of its Green Contracts to align them with the renewable consumption framework under the Ministry of Power notification dated 20 October 2023. IEX is to classify contracts by source - Wind, Hydro, DRE and Other RE - as per the RCO notification dated 27 September 2025. Sellers must provide an NOC or standing clearance specifying their category, and fungibility among the four categories follows that notification strictly.
IEX will issue certificates detailing trades in each category, which buyers can use to meet renewable consumption targets and RPO compliance, and discom portfolio sales must name the plants and their sources. The minimum volume in Green-Intra Day and Green-DAC contracts falls from 0.220 MW to 0.1 MW. The National Load Despatch Centre (NLDC) has four weeks to make matching changes to the NOAR portal and T-GNA procedures.
Why it matters for wind: Wind sold through green contracts will be labelled and certified by source, so buyers can count it towards their obligations. The fungibility terms decide how wind-backed trades can be combined with other renewable categories.

3. CERC orders NLDC to issue withheld RECs to a distribution licensee
CERC · 24 May 2026 (Petition 841/MP/2025)
CERC has directed NLDC to issue the remaining 1,19,293 renewable energy certificates (RECs) to India Power Corporation Limited for FY 2024-25. The West Bengal commission had certified 440.127 MU of excess renewable procurement, entitling the licensee to 4,40,119 certificates, but NLDC had issued 3,20,826 after applying the Forum of Regulators Rules, which monitor compliance against the higher of the state or central target.
CERC held that under the REC Regulations, 2022, eligibility for issuance rests solely on renewable procurement in excess of the RPO (renewable purchase obligation) as determined and certified by the concerned State Commission, and that the Forum of Regulators Rules govern monitoring of compliance only.
Why it matters for wind: The order confirms the State Commission's certificate as the basis for REC issue to distribution licensees. That keeps the rules clear for the REC market that wind projects with certificate-linked revenue sell into.
