BESS regulations and advisory

Why storage rules matter now

Battery storage is becoming part of how renewable power is planned and bought. As that happens, the rules around it decide more of a project's value: which support it can receive, which charges it pays and which safety requirements it must meet.

The framework is still developing. Rules have been issued or revised in stages, often with conditions attached:

• The Union Cabinet approved a viability gap funding scheme for battery storage in September 2023. Its terms have since been revised, and further support has been announced.
• Central orders have waived inter-state transmission charges for some storage projects, subject to conditions such as configuration and dates.
• The Central Electricity Authority has amended its safety regulations to add requirements specific to battery storage. They are not yet in force.
• GERC published draft regulations for grid-connected battery storage in May 2026, and it is developing further regulations on storage, ancillary services and grid access.

A project planned on an earlier reading of the rules can find that its position has changed by bid time. None of these, on its own, tells you whether support or a waiver is available for your project. That depends on the terms in force and on how the project is configured and procured.

What to assess for a BESS project

We treat each area below as a question for project-specific assessment, not as a settled answer. For each one, we check whether and how it applies to your project, on the current official text.

• Policy support and viability gap funding: whether any scheme applies to the project, on what conditions and through which procurement route.
• Transmission charges and waivers: whether an inter-state transmission charge waiver, or any other charge treatment, applies to the project as configured and connected.
• Configuration: standalone storage, or storage co-located with solar or wind, and what that choice changes for connection, charges and support.
• Safety requirements: which electrical, fire and equipment safety rules apply to the battery system and the site, and which are not yet in force.
• State tenders and contracts: eligibility, technical and commercial conditions, and the regulatory risks the contract leaves with the developer.
• Regulatory approvals: whether the tariff, the procurement or the contract needs a commission's approval.

Gujarat

For a project in Gujarat, the state layer matters as much as the central one. GERC's regulations and orders, as amended, set the tariff, grid and open access arrangements that an intra-state storage project must work within. Gujarat's renewable procurement regulations also include a storage obligation, which can create demand for storage.

GERC published draft regulations for grid-connected battery storage in May 2026. The draft proposed, among other things, a registration requirement and a minimum size for grid-connected systems. We check GERC's current list of regulations before advising. We tell you clearly whether a provision is in a draft or in a final notified text, and we do not treat a draft as law. Once a rule is notified, a policy impact simulation can show what it means for your plant in numbers.

Where storage is bought through a state utility tender, the tender's terms add a further layer. Where the state position is still being settled, we say so, and we show how the open points could affect the project. If storage is paired with green power for your own use, the open access and captive rules also apply. See green energy open access and captive power advisory.

Before you bid: a tender review checklist

Tender documents often decide more of a storage project's regulatory risk than the general rules do. Before you bid, we review:

1. Eligibility: who may bid, and any conditions on the bidder or the equipment.
2. Technical conditions: size, duration, connection and performance terms, checked against the rules that apply.
3. Charge treatment: which transmission, wheeling and other charges the tender assumes, and whether a waiver is assumed.
4. Change in law: who bears the cost if a rule, charge or scheme term changes after the bid.
5. Approvals: which approvals the bidder must obtain, and by when, according to the documents.

You receive a written list of regulatory risks and the questions to raise before the bid date.

Where we help

Storage is one of several specialist areas within our advisory work. For BESS projects, we help with:

• Regulatory due diligence on a BESS project or portfolio, before investment or financing.
• Tender and contract review, with a list of regulatory risks and the questions to raise.
• Applicability notes on support schemes, transmission charges and safety requirements, written for your project.
• Regulatory inputs to the financial model, so that charges, support and risks show up in the numbers. See financial modelling and regulatory risk.
• Advice where storage sits within a wider solar, wind or hybrid plan. See renewable energy regulatory advisory.
• Following changes in storage and renewable energy rules as they are issued, through renewable energy regulatory updates.

How we work

We agree the question first, for example "Does this tender's charge treatment hold under current orders?" We then read the official text and label each instrument as notified, draft, under petition or announced. We apply it to your project's configuration, connection and timing. You receive a written note with what applies, what is open and what could change. We do not promise support, waivers or outcomes. Read more about how we work.

Practical uses

• A developer checks a state BESS tender before deciding whether to bid.
• An investor reviews a storage portfolio's regulatory position before financing.
• A commercial and industrial buyer considers adding batteries to green power for its own use.
• A solar or wind developer compares standalone and co-located storage for a new site.
