Introduction

Indian businesses are increasingly looking for ways to reduce their dependence on conventional electricity, meet renewable-energy targets and demonstrate progress toward sustainability objectives. Official renewable-energy programme information is available from the Ministry of New and Renewable Energy, while the Ministry of Power publishes electricity-sector policies and updates.

However, not every company can install a large solar power plant on its own premises.

A commercial facility may have:

• Limited rooftop space
• High electricity consumption
• Multiple locations
• Limited access to renewable resources
• Restrictions on installing renewable-energy systems
• A requirement to procure renewable electricity indirectly

This is where Renewable Energy Certificates (RECs) in India can become an important mechanism.

An REC is a market-based instrument associated with renewable electricity generation. India’s REC framework is designed to help address the geographical mismatch between renewable-energy generation and the location of renewable-energy consumption requirements. The REC mechanism also facilitates compliance with applicable renewable-consumption obligations. ( Recregistry India)

Under the current framework, a certificate generally represents 1 MWh of renewable electricity generated and injected into the grid, with technology multipliers applicable to certain eligible projects commissioned after the effective date of the 2022 regulations. ( Recregistry India)

For businesses, understanding how RECs work in India is important when evaluating renewable-energy procurement, compliance strategies and sustainability planning.

What Is a Renewable Energy Certificate?

A Renewable Energy Certificate (REC) is a market-based instrument representing the environmental attribute associated with renewable electricity generation.

In simple terms, renewable electricity has two components:

1. Electricity component

The actual electricity generated and supplied to the grid.

2. Environmental attribute

The renewable characteristic associated with that generation.

Under the REC mechanism, these components can be separated in eligible cases.

The generator can sell the electricity separately while the environmental attribute is represented through RECs. The REC Registry of India explains that eligible renewable generators can either sell renewable electricity as green energy or separately sell the electricity and associated environmental attributes through RECs. ( Recregistry India)

This creates a market where eligible renewable generators can monetize environmental attributes and eligible buyers can procure RECs for applicable renewable-consumption requirements.

Why Was the REC Mechanism Introduced?

Renewable-energy resources are not evenly distributed across India.

Some states have excellent solar or wind resources, while other regions may have limited renewable-energy potential.

The REC framework helps address this mismatch.

For example:

Renewable-rich state → Renewable electricity generation → Grid → REC

while:

Business in another region → Purchases eligible REC → Renewable attribute is accounted for

The REC Registry describes this geographical mismatch between renewable-resource availability and renewable-consumption requirements as one of the key reasons for the REC mechanism. ( Recregistry India)

Who Regulates the REC Framework in India?

The Central Electricity Regulatory Commission (CERC) is responsible for the regulatory framework governing Renewable Energy Certificates. Review the official CERC Renewable Energy Certificate Regulations, 2022 for the governing regulatory text.

CERC notified the CERC (Terms and Conditions for Renewable Energy Certificates for Renewable Energy Generation) Regulations, 2022, which replaced the earlier 2010 framework and amendments. The 2022 framework came into effect on 5 December 2022. ( Recregistry India)

Importantly, CERC’s official website currently lists a First Amendment to the REC Regulations, 2026, so businesses should verify the latest applicable regulations and procedures before making compliance or procurement decisions.

REC vs Green Power Purchase

A green power purchase arrangement generally involves procuring renewable electricity, while an REC represents the environmental attribute under the REC mechanism.

The distinction matters because:

Electricity procurement ≠ REC procurement

A business should determine whether it needs:

• Renewable electricity
• Renewable environmental attributes
• Regulatory compliance
• Corporate sustainability claims
• A combination of these

before selecting a procurement strategy.

How Are RECs Traded in India?

The REC Registry states that RECs can be exchanged through power exchanges authorized by CERC at discovered market prices on specified trading days, or through electricity traders at mutually agreed prices. ( Recregistry India)

The trading process generally involves:

Buyer Bid + Seller Bid → Exchange/Trading Process → Verification → Trade → Redemption

For exchange-based trading, the Central Agency verifies the eligible REC quantity associated with the seller before the trade is finalized. ( Recregistry India)

REC Issuance Process Explained

The REC issuance process can be simplified as:

Renewable Generation

↓

Energy Injection Report (EIR)

↓

Application on REC Portal

↓

Verification by Central Agency

↓

REC Issuance

The REC Registry specifies that renewable-energy generators and eligible captive generating stations apply for an Energy Injection Report through the applicable SLDC/RLDC process, after which they can apply for REC issuance through the REC portal. ( Recregistry India)

What Documents Are Required?

Documentation depends on the entity and stage of the process.

For generator registration, the REC Registry’s checklist includes items such as:

• Online registration application
• Accreditation certificate
• Commissioning certificate/schedule
• Applicable declarations
• Fees and charges information
• Authorized-signatory documentation

For REC issuance, an Energy Injection Report and other applicable documents may be required. ( Recregistry India)

Businesses should always refer to the latest REC Registry checklist before submitting an application.

Example: REC Requirement Calculation

Consider a hypothetical company with an applicable renewable-consumption requirement.

Suppose the relevant electricity consumption is:

10,000 MWh/year

Assume the applicable renewable requirement is:

30%

Required renewable consumption:

10,000 × 30% = 3,000 MWh

Now suppose the company already obtains:

2,000 MWh

through eligible renewable-energy procurement.

Remaining requirement:

3,000 − 2,000 = 1,000 MWh

If the remaining requirement can be met through eligible RECs, the company would need to evaluate procurement of approximately:

1,000 RECs

This is an illustrative example only. Actual compliance calculations must use the applicable regulatory obligation, eligible consumption definition and renewable-energy accounting rules.

Benefits of Renewable Energy Certificates for Businesses

1. Supports Renewable-Energy Procurement

RECs provide a mechanism for businesses to participate in renewable-energy markets even when direct renewable generation is difficult.

2. Helps Address Space Limitations

Businesses without sufficient rooftop or land area can evaluate REC procurement.

3. Supports Compliance

Eligible obligated entities can use RECs for applicable renewable-consumption compliance.

4. Flexible Procurement

RECs can provide flexibility where physical renewable-energy procurement is not sufficient.

5. Supports Renewable-Energy Markets

REC demand creates an additional market mechanism for eligible renewable generators.

6. Can Complement Solar

Businesses can combine physical solar generation with other renewable procurement mechanisms where permitted. Businesses can evaluate commercial and industrial solar solutions for on-site renewable generation.

Limitations of REC Procurement

RECs should not be treated as a substitute for every renewable-energy strategy.

Potential limitations include:

No Direct Electricity Supply

Buying an REC does not physically deliver renewable electricity to the company’s facility.

Market Price Risk

REC prices can change based on supply and demand.

Regulatory Complexity

Eligibility and compliance requirements can change.

Accounting Requirements

Businesses need to maintain appropriate documentation.

Claims Must Be Accurate

A company should not make misleading statements implying that its facility physically consumes the renewable electricity represented by an REC.

RECs and Corporate Sustainability

Companies increasingly publish sustainability information covering:

• Renewable-energy consumption
• Greenhouse-gas emissions
• Energy efficiency
• ESG performance
• Climate targets

RECs may form part of a corporate renewable-energy procurement strategy.

However, companies should clearly distinguish between:

Physical renewable electricity

and

Renewable environmental attributes

This distinction becomes especially important when preparing sustainability reports or communicating renewable-energy claims to customers and investors.

RECs for Manufacturing Companies

Manufacturing facilities often have significant electricity consumption.

Industries that may evaluate renewable-energy procurement include:

• Textile manufacturing
• Automobile manufacturing
• Pharmaceutical manufacturing
• Food processing
• Engineering
• Electronics
• Chemical manufacturing
• Steel and metal processing
• Warehousing
• Data centers

For energy optimization alongside renewable procurement, battery energy storage systems can also be evaluated.

A manufacturer might combine:

Energy Efficiency + Rooftop Solar + Open Access + REC Procurement

depending on its operational requirements and regulatory eligibility. Businesses developing integrated clean-energy infrastructure may also explore EV charging solutions.

REC and Open Access Solar

Open-access renewable electricity and RECs can also be evaluated as separate or complementary strategies.

Open Access Solar:

Business procures renewable electricity through the applicable electricity network arrangement.

REC:

Business procures the eligible environmental attribute represented by the certificate.

The financial and regulatory implications can differ significantly.

Businesses should compare:

• Energy tariff
• Wheeling charges
• Transmission charges
• Banking
• Cross-subsidy surcharge
• Additional surcharge
• REC cost
• Compliance benefits

before choosing a procurement structure.

Frequently Asked Questions

1. What is a Renewable Energy Certificate in India?

An REC is a market-based instrument representing the environmental attribute associated with eligible renewable-energy generation.

RECs can be traded through CERC-authorized power exchanges or through electricity traders under the applicable REC framework. ( Recregistry India)

8. Is REC pricing fixed?

No. REC prices are discovered through the applicable market mechanism and can vary based on supply, demand and regulatory conditions.

9. Can RECs help with renewable-energy compliance?

They can, where the applicable regulations permit their use for the relevant renewable-consumption obligation. Businesses should verify the latest rules applicable to their category.

10. Should a business choose solar, open access or RECs?

It depends on the business’s electricity consumption, available land/roof area, location, regulatory status, renewable-energy targets and financial objectives. In some cases, a combination of physical renewable generation and REC procurement may be appropriate.

Conclusion

Renewable Energy Certificates (RECs) in India provide businesses with a market-based mechanism for participating in renewable-energy procurement and, where permitted, meeting applicable renewable-consumption requirements. The key advantage is flexibility. A company does not necessarily need to generate all of its renewable electricity on-site to participate in the REC mechanism. However, RECs should be understood correctly. They represent renewable environmental attributes and are not the same as physically supplying renewable electricity to a business facility. For companies evaluating their renewable-energy strategy, the right approach is to first understand electricity consumption and regulatory obligations, then compare rooftop solar, captive renewable energy, open access, battery storage and REC procurement. COP Energy can support businesses evaluating practical renewable-energy solutions.
