Quick Answer
Renewable energy law in India now offers developers concrete incentives for production-linked support under the National Green Hydrogen Mission, an inter-state transmission charge waiver for green hydrogen, and 100% FDI under the automatic route. This guide covers the legal framework, PPA clauses, RECs, land acquisition, and corporate procurement structures that determine whether a project stands up commercially and legally.
Renewable energy law India sits at the center of one of the country’s fastest-moving policy areas. The National Green Hydrogen Mission, the inter-state transmission charge waiver, and open access reforms have changed the economics of renewable projects in the last two years. For developers, project finance teams, and corporates entering power purchase agreements, the regulatory detail now decides project viability.
This guide breaks down the legal structures that matter: the green hydrogen mission legal India framework, the clauses that protect a solar power purchase agreement India, renewable energy certificate India trading, land acquisition routes, FDI structures, and corporate procurement models that meet ESG commitments legally. At Altacit Global, we advise developers and corporate buyers on each of these.
National Green Hydrogen Mission: Legal Framework
The National Green Hydrogen Mission, approved in January 2023, is the anchor policy for green hydrogen in India. It targets 5 million metric tonnes of annual green hydrogen production capacity by 2030 and channels support through three legal levers developers should build into their project models.
SIGHT programme: production-linked incentives. The Strategic Interventions for Green Hydrogen Transition (SIGHT) programme provides financial incentives on two fronts: domestic electrolyser manufacturing and green hydrogen production. Incentives are allocated through competitive bidding. For a developer, the SIGHT award changes the project’s revenue stack, so the bid terms and the incentive disbursement conditions must be modeled before financial close.
Inter-state transmission charge waiver. Green hydrogen and its production plants qualify for a waiver of inter-state transmission system (ISTS) charges. This waiver directly lowers the delivered cost of renewable power used for electrolysis. The waiver is time-bound and tied to project commissioning dates, so confirm the operative window against the current Ministry of Power order before you assume the benefit.
Special economic zones and green hydrogen hubs. The Mission designates green hydrogen hubs regions capable of large-scale production and use. Locating a project inside a designated hub or an SEZ can unlock additional fiscal treatment and shared infrastructure. The hub designation also affects land and evacuation planning, so factor it into site selection early.
Power Purchase Agreements (PPAs): Key Clauses
The PPA is the contract that makes a renewable project financeable. In a solar power purchase agreement India or any PPA renewable energy India structure, lenders read the risk allocation before they read the tariff. These are the clauses that decide the deal.
Clause | What to check | Why it matters |
Tenure | Term length, extension and renewal rights | Must align with debt tenure and equipment life |
Tariff structure | Fixed, escalating, or indexed pricing | Determines revenue certainty and lender comfort |
Delivery point | Where title and risk pass to the buyer | Fixes responsibility for evacuation and losses |
Curtailment | Compensation for grid-instructed backdown | Protects revenue when the offtaker or grid cannot take power |
Change in law | Cost pass-through for new taxes, duties, or rules | Critical given the pace of renewable energy policy change |
Termination | Trigger events, notice periods, buyout formula | Governs default outcomes and lender step-in |
Force majeure | Scope of relief and allocation of risk | Determines who bears loss from events outside either party’s control |
The change in law clause deserves particular attention. Renewable energy policy in India changes frequently, duties on imported modules, transmission charge rules, and open access regulations have all shifted within short cycles. A well-drafted change in law clause passes the cost of these changes to the party best able to absorb them, and its absence can strand a project’s returns. We draft and review PPAs so this risk sits where it belongs.
Renewable Energy Certificates (REC) and Trading
A renewable energy certificate India represents the environmental attribute of one megawatt-hour of renewable generation, separated from the underlying electricity. RECs let a buyer claim renewable consumption without a physical power contract.
Trading on IEX and PXIL. RECs trade on the Indian Energy Exchange (IEX) and the Power Exchange India Limited (PXIL) through periodic sessions regulated by the Central Electricity Regulatory Commission (CERC). Prices move within a CERC-notified floor and forbearance band, so a REC-based strategy carries price exposure a physical PPA does not.
Use in BRSR and ESG reporting. RECs support renewable energy claims in Business Responsibility and Sustainability Reporting (BRSR). For listed companies, the energy footprint is one of the nine BRSR Core attributes requiring independent reasonable assurance, and the share of renewable energy sits inside that KPI. RECs used toward that figure must be traceable to source records that survive assurance testing.
Greenwashing risk. A REC claim that cannot be substantiated is a greenwashing exposure. Double-counting a REC, or claiming renewable consumption already claimed by another party, undermines the disclosure and the assurance conclusion built on it. Match every claimed REC to a retired, non-double-counted certificate.
Land Acquisition for Solar/Wind Projects
Land is the first hard constraint on a solar or wind project. The site decides evacuation cost, clearance burden, and construction timeline. Three routes dominate.
- Wasteland and government land schemes. Several states allot revenue wasteland or government land for renewable projects on long-term lease at concessional rates. These schemes reduce upfront cost and shorten aggregation, but carry conditions on commissioning timelines and land use.
- Forest and environmental clearances. A site touching forest land triggers clearance under the Forest (Conservation) Act, 1980. Larger projects and those near ecologically sensitive zones may require environmental clearance under the Environment (Protection) Act framework. Clearance timelines drive the critical path, so start them early.
- Long-term lease structures. Leasing private or government land over 25 to 30 years matched to project life avoids the capital lock-up of outright purchase and simplifies exit. The lease must secure access, evacuation rights, and assignability to lenders.

FDI in Renewable Energy: 100% Automatic Route
Foreign investment in Indian renewable energy is open. The sector permits 100% FDI under the automatic route, meaning no prior government approval is required for most equity investment. This makes India directly accessible to foreign developers, funds, and strategic investors.
Three structures are common:
- Wholly owned subsidiary (WOS). A foreign investor holds 100% of an Indian company that develops and owns the project. This gives full control and a clean structure for consolidated reporting.
- Joint venture (JV). A foreign investor partners with an Indian developer, sharing capital, risk, and local execution capability. The shareholders’ agreement must fix control, reserved matters, and exit clearly.
- Infrastructure Investment Trust (InvIT). Operating renewable assets are pooled into an InvIT to recycle capital and attract long-term investors. InvITs suit developers monetizing a stabilized portfolio.
The FDI route is open, but sector-specific approvals for land, environmental, and grid connectivity still apply. Our Corporate team advises on entry structuring and FDI compliance; see our FDI guide.
Corporate Renewable Procurement: Meeting ESG Commitments Legally
Corporates with net-zero and renewable targets need procurement structures that hold up in disclosure. The BRSR Core energy footprint KPI turns a renewable commitment into an assured number, so the structure must produce evidence, not just intent. Four routes dominate.
Structure | How it works | Best for |
Direct PPA (open access) | Buyer contracts directly with a generator and draws power through open access | Large consumers with steady load and scale to justify open access |
Group captive | Buyer holds at least 26% equity in the generating company and consumes at least 51% of output | Consumers wanting captive-status benefits and tariff certainty |
REC purchase | Buyer sources power conventionally and buys RECs to claim renewable consumption | Consumers with dispersed or smaller loads that cannot support a PPA |
Green tariff | Buyer opts into a discom’s green power tariff at a premium | Consumers wanting a simple, low-administration renewable claim |
Choose a direct PPA if scale and steady load justify open access, and REC purchase if load is small or dispersed. Group captive suits buyers who can meet the 26% equity and 51% consumption thresholds and want captive treatment. Green tariff suits those prioritizing simplicity over cost.
Whichever route a corporate picks, the renewable claim must reconcile to source records. The BRSR Core energy footprint KPI faces reasonable assurance, so the procurement contract and its evidence trail must survive external verification. We help corporates match procurement structure to disclosure obligation.
Build the Legal Structure Before the Project
Renewable energy law India rewards developers who fix the legal structure first the SIGHT incentive terms, the change in law clause, the open access approvals, and the REC traceability that survives assurance. Get these right and the project stands up commercially and in disclosure. Altacit Global advises developers, funds, and corporate buyers across green hydrogen, solar, and wind.

Frequently Asked Questions: Renewable Energy Law India
Q1: How does open access work for corporate buyers in India?
Open access lets a consumer buy power directly from a generator instead of the local distribution company. A corporate buyer needs approval from the relevant State Electricity Regulatory Commission (SERC) and must pay open access charges including a cross-subsidy surcharge, additional surcharge, wheeling, and transmission charges. These charges materially affect the delivered cost, so model them before committing to a direct PPA.
Q2: Should a corporate choose a PPA or REC purchase?
Choose a PPA if the buyer has steady, large load and wants long-term price certainty on physical renewable power. Choose REC purchase if the load is small or dispersed, or if open access is impractical. A PPA delivers physical renewable power plus the environmental attribute; a REC delivers only the environmental attribute, layered onto conventionally sourced power.
Q3: Does a solar project need environmental clearance in India?
It depends on location and scale. A solar project on non-forest, non-sensitive land generally faces a lighter clearance burden. A project touching forest land requires clearance under the Forest (Conservation) Act, 1980, and projects near ecologically sensitive zones may need environmental clearance. Confirm the requirement against the current MoEFCC notifications for your site before construction.
Q4: What is the inter-state transmission charge waiver for green hydrogen?
Green hydrogen production plants qualify for a waiver of inter-state transmission system (ISTS) charges on the renewable power they consume. The waiver lowers the delivered cost of electricity for electrolysis. It is time-bound and tied to commissioning dates, so verify the operative window against the current Ministry of Power order.
Q5: Is 100% FDI allowed in Indian renewable energy?
Yes. The renewable energy sector permits 100% FDI under the automatic route, so most foreign equity investment needs no prior government approval. Sector-specific approvals for land, environment, and grid connectivity still apply regardless of the FDI route.
