1. MNRE allows sale of power from prototype wind turbines and points installation to the ALMM (Wind) list
MNRE · 25 June 2026
MNRE has amended its Revised Guidelines for installation of prototype wind turbine models dated 12 June 2025. The limit of 3 turbines per prototype model for synchronisation and commissioning stays. A new provision says scheduled power from prototype turbines may be purchased by DISCOMs or any other entity at a mutually agreed tariff, or a tariff regulated under CERC or the concerned SERC. The earlier text barred serial production and installation until a model was included in RLMM; the amended text bars installation until the model is included in the ALMM (Wind) list. Other provisions are unchanged.
Why it matters for wind: OEMs introducing new models can sell the test output at an agreed or regulated tariff, and installation now hinges on the ALMM (Wind) list. For developers, the route from prototype to deployable turbine models runs through that list.

2. CERC adopts Rs 6.74/kWh tariff for SJVN's 6,000 MWh peak-power storage tender
CERC · 20 June 2026 (Petition 31/AT/2026)
CERC adopted tariffs for SJVN's tender for 6,000 MWh (1,500 MW x 4 hours) of assured peak power from ISTS-connected renewable energy projects with energy storage, anywhere in India. Sixteen bidders offered 5,260 MW. After the e-reverse auction on 9 October 2025, awards went to Sembcorp Green Infra (150 MW), Reliance NU Energies (750 MW), Solarcraft Power India 8 (150 MW) and ACME Solar Holdings (450 MW), all at Rs 6.74/kWh. The buying entity picks any 4 hours between 18:00 and 24:00, taking up to 200,000 kWh per 100 MW of contracted capacity daily, with 90% monthly availability over a 25-year PPA and declared annual CUF outside peak hours not below 19%.
SJVN told CERC the tariff is about 21% below SECI's FDRE VI tender at Rs 8.50/kWh and Rs 0.10/kWh above NVVN's standalone battery tender at Rs 6.64/kWh, which had viability gap funding; FDRE-4 has none. TNPDCL, BSES Rajdhani, BSPHCL and KSEB have expressed interest. SJVN's trading margin of Rs 0.07/kWh applies only if it provides escrow or a letter of credit to the generators; otherwise it is limited to Rs 0.02/kWh.
Why it matters for wind: Peak-power tenders with storage are open to any ISTS-connected renewable source, so wind-backed bids can compete for them. The adopted Rs 6.74/kWh, set without viability gap funding, is a reference point for pricing evening-peak supply.
