Power & Carbon MarketsIndia's REC Market and RCO Compliance: What Industrial Consumers Must Understand About RECs, Physical RE, and the CCTS Scope 2 Boundary
India's Renewable Energy Certificate market cleared at Rs 340 per MWh in March 2026. A massive 187.20 lakh certificates traded across FY2025-26, marking the highest annual volume on the IEX to date. Meanwhile, industrial consumers operating under the Renewable Consumption Obligation face a sharply rising mandatory renewable share. This requirement climbs from 29.91% of total electricity consumption in FY2024-25 to 43.33% by FY2029-30. Facilities can meet this mandate through physical renewable energy procurement, RECs, or a CERC buyout payment. However, there is a critical boundary that every CCTS covered plant and CBAM exposed exporter must clearly understand. While RECs satisfy the RCO, they absolutely do not reduce Scope 2 GEI under India's Carbon Credit Trading Scheme, nor are they recognized as reducing embedded Scope 2 emissions under CBAM. The CCTS gate to gate methodology counts the actual electricity consumed at the actual emission factor of the source, not the certificate purchased to represent it. For an aluminium smelter or steel plant needing to resolve three regulatory obligations simultaneously, physical renewable electricity is not just preferable. It is the only instrument that does all three jobs at once.
Key Takeaways
India's REC market saw 187.20 lakh certificates traded in FY2025-26, setting a new record on the IEX with a 5% year on year increase. The March 2026 sessions cleared at Rs 340 per REC. One REC represents 1 MWh of electricity generated from renewable sources. Under the 2022 CERC regulations, floor and ceiling prices were completely removed. Prices are now fully market determined through closed auctions on IEX, PXIL, and HPX.
The Renewable Consumption Obligation supersedes the older Renewable Purchase Obligation for all designated consumers. It brings energy intensive industries like steel, aluminium, and cement directly into a binding national renewable mandate. The target rises from 29.91% in FY2024-25 to 43.33% by FY2029-30. Non compliance carries steep penalties under the Energy Conservation Act, reaching up to Rs 10 lakh plus Rs 10,000 per day of continued violation.
Facilities have three ways to comply with the RCO. First, they can directly consume physical renewable electricity. Second, they can purchase RECs from the exchange. Third, they can pay the CERC determined buyout price. However, only the first route of physical renewable energy simultaneously satisfies the CCTS Scope 2 boundary and the CBAM Scope 2 emission calculation.
The CCTS methodology calculates Scope 2 emissions based on the actual electricity consumed multiplied by the applicable emission factor. A REC simply proves that 1 MWh of renewable electricity was generated somewhere on the grid. It does not change the emission factor of the electricity your plant actually consumed. If a smelter buys RECs but draws power from a coal plant at 0.9 tCO2/MWh, it will still report that 0.9 factor for CCTS compliance.
The same strict logic applies to the European Union's CBAM. Importers must verify the embedded Scope 1 and Scope 2 emissions of their goods. The EU methodology calculates electricity related emissions at the actual emission factor of the source powering the production process. RECs are entirely ignored for this purpose. Only physically sourced renewable electricity reduces your CBAM certificate costs.
The REC Market: Structure, Pricing, and the FY2026 Surge
India established the Renewable Energy Certificate mechanism to separate the 'green' value of electricity from the actual physical power. When a renewable energy plant feeds power into the grid without a special preferential tariff, it earns one REC for every megawatt hour generated. Buyers, ranging from distribution companies and captive users to voluntary purchasers, acquire these RECs to meet their regulatory obligations or for sustainability reporting.
Following the CERC's 2022 regulatory update, artificial floor and ceiling prices were entirely removed. Previously, RECs had a floor near Rs 1,000 per MWh and a ceiling of Rs 3,900 per MWh. Following deregulation, market clearing prices dropped sharply and settled in the Rs 300 to 500 range. This price reflects a market where renewable generation supply has grown rapidly, but RPO compliance gaps at the state level still constrain overall demand.
The REC market saw a massive volume increase in FY2025-26, trading 187.20 lakh certificates. The surge in the fourth quarter, which hit a record 71.70 lakh RECs, reflects urgent year end compliance demand. Industrial consumers and distribution companies rushed to settle their RCO obligations before the March 31 deadline.
To provide a structured safety valve, the CERC proposed a buyout price of Rs 245 per MWh for FY2024-25. This price is intentionally set below the market rate to encourage direct REC purchases while offering an escape hatch for entities struggling to source physical renewable energy in time. The collected buyout payments flow directly to the Central Energy Conservation Fund to finance further renewable development.
The RCO Framework: Industrial Obligations
The Revised Renewable Consumption Obligation Guidelines issued in late 2025 supersede older RPO notifications for designated consumers. The Ministry of Power clarified that industrial consumers operating captive power plants or procuring power through green open access are now primarily subject to the RCO framework.
| Financial Year | Total RCO Target | Wind | Hydro | DRE | Other RE |
|---|---|---|---|---|---|
| FY2024-25 | 29.91% | 0.81% | 0.43% | 1.40% | 27.27% |
| FY2025-26 | 31.38% | 1.05% | 0.63% | 2.10% | 27.60% |
| FY2026-27 | 33.23% | 1.54% | 0.77% | 2.80% | 28.12% |
| FY2027-28 | 35.78% | 2.10% | 0.91% | 3.22% | 29.55% |
| FY2028-29 | 38.95% | 2.45% | 1.12% | 3.85% | 31.53% |
| FY2029-30 | 43.33% | 3.48% | 1.33% | 4.50% | 34.02% |
For a captive power plant user, the RCO applies strictly to the share of total electricity consumed through the captive plant or open access. For example, a smelter consuming 14 MWh per tonne of aluminium entirely through captive coal power must ensure that 29.91% of that power comes from renewable sources to meet the current year's mandate. At the full 43.33% target in FY2030, this renewable requirement rises to roughly 6.07 MWh per tonne.
The revised 2025 framework also introduced major flexibilities. Virtual Power Purchase Agreements are now formally recognized, allowing corporates to secure RECs without physical power delivery. Companies can also meet RCO on a consolidated group level, leveraging surplus green power at one site to offset deficits at another. Finally, self generated renewable energy stored in battery systems now officially counts toward RCO compliance.
The Critical Boundary: Why RECs Fall Short for CCTS and CBAM
This is the most commercially critical distinction in India's renewable energy landscape. Many sustainability teams wrongly assume that purchasing RECs resolves all their renewable energy obligations simultaneously. While RECs perfectly satisfy the RCO, they do absolutely nothing for CCTS emissions reductions or CBAM exposure.
Why RECs do not reduce CCTS Scope 2 GEI: The CCTS gate to gate methodology calculates Scope 2 emissions by multiplying your plant's electricity consumption by the actual emission factor of the electricity source. A REC only certifies that green power was generated somewhere else on the grid. It does not alter the emission factor of the power your plant consumed. If your facility runs on a captive coal plant emitting 0.9 tCO2/MWh, that is the exact factor you must report to the CCTS, regardless of how many RECs you buy. Only the physical delivery of renewable electricity directly reduces your Scope 2 contribution.
Why RECs do not reduce CBAM Scope 2 embedded emissions: The EU CBAM requires importers to submit verified embedded emissions data. The EU methodology calculates electricity related emissions using the actual emission factor of the source powering the production process. The EU verification framework completely ignores RECs. Only physically sourced renewable electricity, backed by a verifiable near zero emission factor, will actually reduce your CBAM certificate costs.
REC Purchase at Rs 340/MWh
- RCO Compliance: Yes. Fully satisfies the percentage target.
- CCTS Reduction: No. GEI is calculated at the actual source emission factor.
- CBAM Reduction: No. EU methodology ignores RECs.
- Best for: Plants where RCO is the only regulatory pressure, or for voluntary sustainability reports.
- Cost: Lowest upfront cost with no capex required.
Physical RE via captive or open access
- RCO Compliance: Yes. Physical RE fully satisfies the mandate.
- CCTS Reduction: Yes. Near zero emission factor directly replaces coal in the GEI calculation.
- CBAM Reduction: Yes. Verified near zero Scope 2 eliminates CBAM certificate costs for electricity.
- Best for: All CCTS covered plants and EU exporters.
- Cost: Higher upfront capex, but the combined regulatory value often justifies the investment.
The comparison makes the strategic decision obvious. For an aluminium smelter exporting to the EU and facing tight CCTS targets, the economics point overwhelmingly toward physical renewable energy. Physical RE is not just a compliance tool, it is a high return operational investment.
Virtual Power Purchase Agreements provide a middle path for companies with constrained physical procurement options. In a VPPA, the corporate agrees to purchase renewable electricity at a strike price. The electricity is sold to the grid, and the corporate receives the resulting RECs. A VPPA successfully satisfies RCO compliance. However, because VPPAs do not deliver physical green energy to the plant, they do not reduce CCTS Scope 2 GEI or CBAM embedded Scope 2 emissions. For companies solely focused on RCO compliance, VPPAs are highly effective. But for plants under CCTS or CBAM pressure, VPPAs provide only partial relief.
Compliance Deadlines and Operational Efficiency
The RCO compliance calendar requires certified energy accounts to be submitted by 31 July each year. Compliance reports, detailing how any shortfalls were addressed through RECs or buyouts, are due by 31 December for subsequent years. These submissions are processed through the BEE's web based monitoring tool.
CCTS GHG reports must be submitted within four months of the financial year end, which lands around 31 July 2026 for the FY2025-26 cycle. This creates a critical overlap. An industrial consumer submitting a GHG report for CCTS is essentially reporting the exact same Scope 2 electricity consumption data already measured for the RCO. Because both frameworks share the same energy measurement boundary, a properly configured energy management system can produce data for both compliance reports simultaneously. Treating RCO and CCTS as isolated reporting tasks creates unnecessary administrative bloat.
Frequently Asked Questions
Does purchasing RECs reduce a plant's GEI under the CCTS?
No. The CCTS methodology calculates Scope 2 emissions by multiplying your plant's electricity consumption by the actual emission factor of the electricity source. A REC only proves that renewable electricity was generated somewhere else. It does not alter the emission factor of the power your plant consumed. Only physical renewable electricity delivered directly to the plant reduces CCTS Scope 2 GEI.
What is the current REC clearing price in India and how is it determined?
The most recent clearing price was Rs 340 per REC at the IEX sessions in March 2026. Following the removal of floor and ceiling prices in late 2022, REC prices are fully market determined through closed auctions held twice a month. The price fluctuates based on the balance between renewable capacity additions and the compliance demands of industrial consumers.
What is the difference between RPO and RCO for industrial consumers?
The older Renewable Purchase Obligation primarily targeted electricity distribution companies under the Electricity Act 2003. The newer Renewable Consumption Obligation, under the Energy Conservation Act 2022, specifically targets designated energy intensive industries like steel, aluminium, and cement. The Ministry of Power has clarified that for open access and captive users, the RCO supersedes earlier RPO notifications, creating a single, uniform national mandate.
