What is CERC
The Central Electricity Regulatory Commission is India’s central electricity sector regulator, constituted under the Electricity Act 2003. CERC’s mandate covers tariffs for inter-state generation, inter-state transmission, central public sector undertakings like NTPC, NHPC and POWERGRID, and the rules governing inter-state trading and power exchanges.
For solar specifically, CERC sets benchmark tariffs that state SERCs reference, issues the Renewable Energy Certificate (REC) framework, regulates large utility solar PPAs through SECI and central agencies, and adjudicates disputes between generators and central DISCOMs.
CERC is the technical-economic regulator. CEA writes technical standards. SERCs handle state-level tariffs. MNRE runs the renewable schemes.
| Body | Role |
|---|---|
| CERC | Central tariffs, REC framework, inter-state PPA disputes |
| CEA | Technical standards |
| SERCs | State-level tariffs, including rooftop net metering |
| MNRE | Renewable schemes |
CERC explained simply
CERC is the central referee for the electricity market. Inter-state transmission charges, central PSU tariffs, REC markets and inter-state PPA disputes all fall under their jurisdiction. State-level rooftop solar tariffs go to SERCs, not CERC.
Why CERC matters
Central tariff setting. NTPC, NHPC, POWERGRID and other central PSUs follow CERC tariff orders.
REC market. CERC issues RECs that drive the renewable purchase obligation market.
Inter-state PPA enforcement. Disputes between SECI and DISCOMs are adjudicated at CERC.
Market design. Power exchange rules, real-time market and ancillary services markets are CERC frameworks.
Late payment enforcement. The Late Payment Surcharge Rules 2022 operate within CERC’s regulatory framework.
How CERC works
- Issues regulations through public consultation.
- Adjudicates tariff petitions from generators and transmission utilities.
- Hears disputes through formal hearings.
- Issues binding orders.
- Appeals go to APTEL.
Major CERC outputs relevant to solar
| Regulation | Scope |
|---|---|
| CERC Tariff Regulations 2024 | Methodology for central generation and transmission tariffs |
| Late Payment Surcharge Rules 2022 | DISCOM payment discipline |
| Renewable Energy Certificate Regulations | REC issuance and trading |
| Inter-State Transmission System (ISTS) Regulations | Transmission charges and access |
| Indian Electricity Grid Code | Grid operation rules |
| Power Market Regulations 2010 | Power exchange framework |
Real-world applications
SECI solar PPAs and discovered tariffs, which developers typically stress-test with a solar financial modeling tool before bidding, benchmarking the discovered tariff against their own LCOE.
REC trading for renewable purchase obligation compliance.
NTPC solar plant tariff determination.
Late payment claims by IPPs against DISCOMs.
POWERGRID transmission charge setting.
Advantages of CERC framework
Statutory backing under Electricity Act 2003.
Independence from operational pressures.
Public consultation in regulation drafting.
Predictable adjudication process.
National scope coordinates state action.
Limitations
Jurisdictional split with SERCs causes some overlap.
Order implementation depends on DISCOM willingness.
Tariff orders sometimes face protracted APTEL appeals.
REC market depth has been thin in some periods.
Indian market context
The CERC Tariff Regulations 2024 superseded the 2019 edition with updated benchmarks, arriving against a backdrop of broader state-level tariff increases discussed in Electricity Tariff Hikes in 2026, Why Solar Pays Off Faster Now.
The REC framework has gone through multiple revisions, with the latest CERC REC Regulations 2022 introducing changes around floor price and validity.
Late Payment Surcharge Rules 2022 created mechanisms for DISCOMs to clear renewable energy dues with escalating consequences.
Green Term-Ahead Market (GTAM) and Green Day-Ahead Market (GDAM) on power exchanges operate under CERC framework.
Standards and certifications
| Standard | Scope |
|---|---|
| Electricity Act 2003 | Statutory basis |
| CERC Tariff Regulations 2024 | Tariff methodology |
| CERC REC Regulations | Certificate framework |
| Late Payment Surcharge Rules 2022 | Payment discipline |
| Power Market Regulations | Exchange framework |
Key takeaways
CERC is the central electricity regulator setting tariffs for central generation and transmission, regulating the REC market, and adjudicating inter-state electricity disputes. State rooftop solar tariffs and net metering rules are set by SERCs, not CERC. The Tariff Regulations, REC framework and Late Payment Surcharge Rules are the most relevant CERC outputs for the solar sector.
