The Haryana Electricity Regulatory Commission has admitted SJVN LimitedтАЩs tariff adoption petition for a major standalone battery storage project.
The petition is Petition No. 28 of 2026.
It has been filed with Interlocutory Application No. 16 of 2026.
The filing has been made under Section 63 of the Electricity Act, 2003.
The project is a 250 MW / 500 MWh standalone Battery Energy Storage System in Haryana.
HERC admitted the petition on May 11, 2026.
The Commission fixed the next hearing for May 14, 2026 at 11:30 AM.
Uttar Haryana Bijli Vitran Nigam Limited has been named as the principal respondent.
The hearing will examine adoption of tariff discovered through competitive bidding.
If adopted, the tariff will become the basis for the storage procurement arrangement.
The proposed BESS has a power capacity of 250 MW.
It has an energy storage capacity of 500 MWh.
This implies a two-hour discharge duration.
Such a configuration is commonly used for evening peak shifting.
The system can charge during lower-cost solar hours and discharge during peak demand periods.
Haryana faces rising evening demand pressure.
Peak demand has repeatedly touched high levels.
The state also needs flexible capacity to balance renewable procurement.
Standalone BESS can help shift surplus renewable energy from midday to evening.
It can also reduce dependence on costly real-time market purchases during peak hours.
Battery storage is becoming more important because exchange prices have shown sharp evening volatility.
Real-Time Market prices have touched the Rs. 10,000/MWh cap during multiple evening hours.
This makes storage economically relevant for DISCOMs.
A two-hour battery can reduce exposure to the most expensive peak blocks.
SJVN has traditionally been associated with hydropower.
Its project base includes hydro assets across Himachal Pradesh, Uttarakhand, and the eastern Himalayan region.
The Haryana BESS petition shows the companyтАЩs shift into renewable and storage-linked infrastructure.
This diversification is important as storage becomes central to IndiaтАЩs grid planning.
The petition has been filed under Section 63.
This means HERC will not determine tariff on a cost-plus basis.
Instead, it will examine whether the bidding process was transparent and competitive.
If satisfied, the Commission can adopt the discovered tariff.
This route provides regulatory certainty for both the developer and the procuring utility.
UHBVNL and DHBVN could benefit from firm storage-backed capacity.
Once tariff is adopted, UHBVNL may need to enter into a Battery Energy Storage Purchase Agreement.
The storage system can support evening supply reliability.
It can also help improve demand-supply balancing at the state level.
Industrial consumers in HaryanaтАЩs Faridabad-Gurugram belt could benefit indirectly.
Reliable evening supply is important for commercial and industrial users.
Battery storage can reduce grid stress during peak periods.
It can also lower the need for emergency procurement if deployed efficiently.
HaryanaтАЩs 250 MW / 500 MWh standalone BESS petition is one of the larger state-level storage tariff filings in 2026.
The May 14 hearing will be important for price discovery, storage procurement, and regulatory treatment.
If approved, the project could become a benchmark for future utility-scale battery storage procurement in India.
