Karnataka has one of India's most progressive solar policy environments — from KERC net metering regulations to PM Kusum implementation and the state's own MNRE top-up subsidies. Here is what it means for anyone installing solar in Karnataka in 2024–25.
Karnataka's Solar Policy Landscape
Karnataka's renewable energy ecosystem is governed by multiple overlapping policies and regulators. Understanding which layer applies to your installation helps you maximise benefits and avoid compliance issues.
- MNRE (Ministry of New and Renewable Energy) — Central government body overseeing PM Surya Ghar and national solar programmes
- KERC (Karnataka Electricity Regulatory Commission) — State regulator setting tariffs, net metering rules, and DISCOM obligations
- BESCOM / HESCOM / GESCOM — Distribution companies operating in different Karnataka regions; BESCOM covers Bangalore and surrounding districts
- KREDL (Karnataka Renewable Energy Development Ltd) — State nodal agency for renewable energy implementation
KERC Net Metering Regulations (2024 Update)
The Karnataka Electricity Regulatory Commission updated its net metering framework in 2023–24, reinforcing homeowners' rights to rooftop solar and grid connectivity. Key provisions:
- DISCOMs cannot refuse net metering applications from eligible residential consumers without documented technical grounds
- Net meter installation must be completed within 60 days of application approval
- Surplus energy credits can be carried forward for 12 billing cycles (12 months)
- Year-end surplus is settled at the APPC (Average Power Purchase Cost) rate — currently ₹3.50–4.50 per unit depending on the DISCOM
- No restriction on the number of net metering connections per LT feeder — a common bureaucratic barrier in some other states
Under KERC regulations, BESCOM is obligated to process your net metering application and install the bidirectional meter within stipulated timelines. If your application is delayed without reason, you can file a complaint with the KERC Consumer Grievance Redressal Forum.
Karnataka New Energy Policy 2024
Karnataka's state government released an updated New Energy Policy in 2024 targeting 10 GW of solar capacity by 2030. For residential solar, the key impacts are:
- Rooftop solar targets: BESCOM and other DISCOMs have annual targets for rooftop solar connections, meaning they are incentivised (and required) to process applications efficiently.
- Green building incentives: New residential buildings meeting rooftop solar requirements may qualify for faster BBMP approvals under green building norms.
- KSPDCL installations on government buildings: Large-scale government installations create installer capacity and drive down component costs for residential buyers.
State Subsidies in Karnataka
| Scheme | Applicable To | Benefit |
|---|---|---|
| PM Surya Ghar (Central) | Residential rooftop, all of India | ₹30,000–₹78,000 direct subsidy |
| Karnataka state top-up | Residential, through KREDL | Additional 10–15% on eligible systems |
| PM Kusum Component-B | Agricultural solar pumps | 30% central + 30% state = 60% subsidy |
| MSME solar scheme | Small businesses, service connections | SIDBI and state financing at preferential rates |
BESCOM Service Area: Am I Covered?
BESCOM (Bangalore Electricity Supply Company) supplies electricity to Bangalore Urban, Bangalore Rural, Chikkaballapur, Kolar, Tumkur, Ramanagara, and Chitradurga districts. If your property is in one of these districts, BESCOM is your DISCOM and the net metering application goes to them.
Other Karnataka districts are served by HESCOM (Hubli-Dharwad), GESCOM (Gulbarga), MESCOM (Mangalore), or CESC (Chamundeshwari) — each with similar net metering frameworks under KERC oversight. SunVana operates across all BESCOM and HESCOM areas.
RPO and Why It Drives Solar Growth
Renewable Purchase Obligations (RPOs) require electricity distributors to source a minimum percentage of their power from renewable sources. Karnataka's RPO targets are among India's most ambitious, which means DISCOMs actively need rooftop solar consumers to count towards their targets. This regulatory pressure is one reason BESCOM is generally cooperative with residential solar applications — they need your system online as much as you do.
