The Power Sector Exclusion – Why India's Carbon Market Starts Without 40% of Its Emissions
Introduction: The Elephant in the Room
India's Carbon Credit Trading Scheme (CCTS) is one of the world's largest new carbon markets, covering approximately 490 obligated entities across seven energy-intensive sectors and an estimated 700 million metric tonnes of CO₂ equivalent annually.
But it starts without its biggest emitter.
The power sector, which accounts for roughly 55% of India's greenhouse gas emissions, sits outside the initial CCTS compliance boundary and is kept under voluntary participation. Its exclusion simplifies implementation while recognising the complexities of electricity market regulation.
This is not a minor omission. In other carbon markets, power utilities are among the most active participants, and fuel-switching dynamics between coal and gas are among the strongest drivers of carbon price movements.
Without the power sector, the CCTS will lack the primary channel through which carbon pricing shapes energy investment. The question is not whether the power sector should be included—it is when, and how.
This guide examines the implications of the power sector's exclusion from India's carbon market, the regulatory hurdles to its eventual inclusion, and what this means for businesses and investors.
The Scale of the Gap: 55% of National Emissions
The Numbers
| Metric | Value |
|---|---|
| Power sector share of India's GHG emissions | ~55% |
| Current CCTS coverage | ~490 entities, 477 million tCO₂e |
| Power sector excluded | Yes — kept under voluntary participation |
Why This Matters
The power sector is India's single largest source of greenhouse gas emissions. Leaving it outside the CCTS means the market's compliance boundary omits the sector with the greatest emissions reduction potential.
The Global Context
In carbon markets worldwide, the power sector is typically included from the start or integrated early. India's decision to exclude the power sector initially is a notable departure from international practice.
The Risk
Without the power sector, scarcity will depend more heavily on other energy-intensive sectors. That can make procurement more selective and can concentrate demand in a smaller part of the market.
Why the Power Sector Matters for Carbon Markets
The Power Sector's Unique Role
The power sector is different from other industrial sectors in several important ways:
| Factor | Why It Matters |
|---|---|
| Scale | Largest single source of emissions |
| Fuel switching | Coal-to-gas switching is a key abatement lever |
| Trading frequency | Utilities trade continuously to hedge emissions exposure |
| Price discovery | Active participation drives continuous price discovery |
The Fuel-Switching Channel
Fuel-switching dynamics between coal and gas are among the strongest drivers of carbon price movements in mature carbon markets. When carbon prices rise, power generators switch from coal to gas, reducing emissions and creating a direct link between carbon price and energy investment decisions.
The Continuous Trading Effect
Power utilities trade continuously to hedge their emissions exposure. This continuous trading activity is essential for price discovery and market liquidity.
Without the Power Sector
Their initial absence will concentrate compliance demand among industrial firms whose trading may cluster around settlement deadlines, weakening the informational content of periodic market-clearing prices.
The Global Experience: Power Utilities as Market Makers
The EU ETS
In the European Union Emissions Trading System (EU ETS), power utilities are among the most active participants. Their continuous trading activity provides liquidity and price discovery that benefits all market participants.
The China ETS
China's national ETS initially included the power sector, recognising its importance for market development.
The California Cap-and-Trade
California's cap-and-trade program includes electricity generators and importers, making the power sector a key participant in price discovery.
The Lesson for India
In other carbon markets, power utilities are among the most active participants. Their inclusion is essential for market liquidity and continuous price discovery.
The Coal-Gas Fuel Switching Channel: What India Is Missing
The Channel
In carbon markets with power sector inclusion, coal-to-gas fuel switching is a primary channel through which carbon prices drive emissions reductions. When carbon prices increase, power generators switch from higher-emitting coal to lower-emitting natural gas.
Why India Is Missing This
India's power sector is heavily dependent on coal. The absence of a well-developed natural gas market and pipeline infrastructure limits the fuel-switching channel.
The IEEFA Perspective
Future integration will need to address how carbon costs interact with India's electricity regulatory framework, particularly dispatch and merit-order decisions.
Without Fuel Switching
Without the fuel-switching channel, the CCTS will lack the primary mechanism through which carbon pricing shapes energy investment decisions.
The Consequence: Concentrated Demand, Weakened Price Discovery
The Demand Concentration Problem
Without the power sector, compliance demand is concentrated among industrial firms. These firms trade less frequently than power utilities, and their trading may cluster around settlement deadlines.
The Price Discovery Problem
The exclusion of financial intermediaries and power sector participants means both supply and demand will remain relatively inelastic in the early years, with trading likely to cluster around settlement deadlines.
The Liquidity Problem
Less frequent trading means less liquidity, which means less continuous price discovery. This makes it harder for firms to use the carbon price signal for long-term investment decisions.
The Result
The market may struggle to generate continuous price discovery, which is essential for long-term investment decisions.
The Regulatory Hurdle: Electricity Act 2003 and Tariff Determination
The Legal Framework
Future power sector integration will need to address the statutory tariff determination process under the Electricity Act 2003, which lacks an established framework for treating carbon compliance costs as a legitimate, automatic pass-through.
The Tariff Determination Problem
Under the current framework, electricity tariffs are determined by regulatory commissions based on a cost-plus or performance-based approach. There is no established mechanism for passing through carbon compliance costs.
The Regulatory Coordination Challenge
Carbon cost recognition would need to be coordinated across the CERC and state electricity regulatory commissions—a complex institutional challenge.
The IEEFA Warning
Without a credible integration roadmap, the CCTS will lack the primary channel through which carbon pricing shapes energy investment.
The Change-in-Law Provision: A Potential Pathway
What Is the Change-in-Law Provision?
India's power sector has enabling features, including change-in-law provisions in power purchase agreements. These provisions allow for cost pass-through when new laws or regulations impose additional costs on power generators.
Why This Matters
The change-in-law provision could provide a pathway for passing through carbon compliance costs to electricity consumers, reducing the regulatory hurdle to power sector inclusion.
The IEEFA Perspective
International experience shows that regulated electricity markets can also support carbon pricing. India's power sector has enabling features that could facilitate integration.
The Need for Coordination
Future integration will need careful coordination between carbon market and electricity regulators.
The Integration Challenge: Coordinating Carbon and Electricity Regulation
The Regulatory Landscape
India's electricity sector is regulated by a complex framework involving:
| Regulator | Role |
|---|---|
| Central Electricity Regulatory Commission (CERC) | Central electricity regulation |
| State Electricity Regulatory Commissions (SERCs) | State-level electricity regulation |
| Grid Controller of India | Grid operations |
The Coordination Challenge
Carbon cost recognition would need to be coordinated across the CERC and state electricity regulatory commissions—a complex institutional challenge.
The Dispatch and Merit-Order Challenge
Carbon costs would affect dispatch and merit-order decisions, creating a direct link between carbon pricing and electricity generation decisions. This requires careful regulatory design.
The IEEFA Recommendation
Future integration will need to address how carbon costs interact with India's electricity regulatory framework, particularly dispatch and merit-order decisions.
The IEEFA Perspective: Without the Power Sector, No Primary Channel
The Core Finding
Without a credible integration roadmap, the CCTS will lack the primary channel through which carbon pricing shapes energy investment.
Why This Matters
The power sector is the single largest source of emissions and the primary channel through which carbon pricing can influence energy investment decisions. Without it, the CCTS's impact on the energy sector will be limited.
The Sequencing Question
The IEEFA report examines the implications of initially excluding India's power sector. The question is not whether the power sector should be included, but when and how.
The Opportunity
India has the advantage of learning from the costly missteps of earlier movers. The CCTS can design a power sector integration pathway that avoids the problems faced by other markets.
The Three Stages: When and How Should Power Sector Integration Happen?
Phase 1: Initial Stage (2026-2027)
- Power sector excluded
- Focus on establishing credible MRV standards and enforcement
- Building market infrastructure
Phase 2: Future Directions and Market Maturation (2028-2030)
- Expanding sectoral scope to include the power sector
- Designing the regulatory framework for cost pass-through
- Coordinating carbon and electricity regulation
Phase 3: Foundational Design Changes (2030+)
- Full integration of the power sector
- Transition to absolute emissions cap
- Introduction of auctioning
The IEEFA Recommendation
Priority should go to foundational elements: credible stringency, robust MRV, and genuine enforcement, with more advanced features designed early but introduced only as the market matures.
The International Experience: Lessons from the EU, China, and California
The EU ETS
The EU ETS included the power sector from the start. Power utilities became among the most active participants, providing liquidity and price discovery.
The China ETS
China's national ETS initially included the power sector, recognising its importance for market development.
The California Cap-and-Trade
California's cap-and-trade program includes electricity generators and importers, making the power sector a key participant in price discovery.
The Lesson for India
International experience shows that regulated electricity markets can also support carbon pricing. India's power sector has enabling features that could facilitate integration.
