Net Metering in Karnataka
As one of the leading states in renewable energy adoption, Karnataka has established a robust Net Metering Policy to promote the use of solar power. The state government aims to reduce dependence on conventional power sources and encourages residential, commercial, and industrial consumers to install solar rooftop systems. Through net metering, Karnataka allows consumers to generate their own electricity and export excess energy to the grid, thereby reducing electricity bills and promoting sustainable energy usage.
In this blog, we will explore the specifics of Karnataka’s net metering policy, its benefits, and a cost breakdown for setting up a solar rooftop system in the state.
What is Net Metering?
Net metering is a system where consumers with solar power systems can connect to the grid, use the electricity they generate, and send any excess back to the grid. The consumer earns credits for the energy exported, which can be used to offset future electricity bills. The consumer is billed based on the net energy used—that is, the difference between the energy imported from the grid and the energy exported.
Karnataka’s net metering policy makes it easier for residents and businesses to reduce their electricity bills and promote renewable energy, making it a win-win for both consumers and the environment.
Key Features of Karnataka Net Metering Policy
1. Eligibility Criteria
- Consumer Categories: Residential, commercial, industrial, and institutional consumers.
- System Size: Solar rooftop systems ranging from 1 kW to 1 MW are eligible.
- Connection Type: Consumers must be connected to Karnataka Power Transmission Corporation Limited (KPTCL) or other distribution companies (DISCOMs) in the state.
2. Solar System Capacity
- The solar capacity of the rooftop system should not exceed the sanctioned load or contract demand of the consumer’s existing connection.
- Typically, the maximum solar system capacity allowed is 80% of the consumer’s sanctioned load.
3. Billing and Settlement
- A bi-directional meter is installed to track both energy imported from the grid and energy exported to the grid.
- Consumers are billed for the net energy consumed (imported minus exported).
- Settlement Period: Energy credits are settled monthly. If there is any surplus energy at the end of the billing cycle, it can be carried forward.
4. Installation and Maintenance
- The cost of installation is borne by the consumer.
- Consumers are responsible for the maintenance of the solar system, ensuring its optimal performance.
- Approved vendors and installers must be used for solar installations, complying with state regulations.
5. Government Incentives and Subsidies
- The Ministry of New and Renewable Energy (MNRE) provides subsidies for solar rooftop systems up to 40% for systems up to 3 kW and 20% for systems between 3 kW and 10 kW.
- Karnataka also supports various schemes to promote renewable energy, reducing the initial cost of installation for consumers.
Benefits of Net Metering in Karnataka
1. Reduced Electricity Bills
Consumers can lower their electricity bills by generating their own solar power. Excess energy exported to the grid earns credits, which can offset future electricity consumption. Over time, this leads to significant savings.
2. Environmental Impact
By using solar energy, consumers reduce their carbon footprint and contribute to a greener environment. Solar energy is a clean, renewable resource that helps in reducing greenhouse gas emissions.
3. Energy Independence
Net metering allows consumers to become less dependent on the grid by generating and using their own electricity. This is particularly beneficial in areas with frequent power outages or rising electricity costs.
4. Long-Term Savings
Although the upfront cost of installing a solar system may seem high, the savings on electricity bills, combined with government incentives, ensure a quicker payback period, typically between 5 to 8 years.
