Net Metering In Kerala
Kerala, a state known for its progressive policies on renewable energy, has implemented a Net Metering Policy to promote the use of solar power. This policy encourages residential, commercial, and industrial consumers to adopt solar rooftop systems, helping reduce electricity costs while also contributing to environmental sustainability. Kerala’s government, through its distribution companies, has made it easier for consumers to generate their own electricity, with any excess being exported to the grid for credits.
In this blog, we will discuss how net metering works in Kerala, the benefits of the policy, and a breakdown of the costs involved in setting up a solar rooftop system in the state.
What is Net Metering?
Net metering is a billing mechanism that allows consumers with renewable energy systems, particularly solar, to export excess electricity generated by their systems to the grid. The exported electricity is recorded, and consumers earn credits, which can be used to offset future electricity consumption. Consumers are billed based on the net energy—the difference between the energy imported from the grid and the energy exported to the grid.
Net metering in Kerala aims to make solar power more accessible and affordable for consumers, reducing electricity bills and supporting the state’s shift toward cleaner energy sources.
Key Features of Kerala’s Net Metering Policy
1. Eligibility Criteria
- Consumer Types: Residential, commercial, industrial, and institutional consumers are eligible.
- System Size: Solar rooftop systems with a capacity ranging from 1 kW to 1 MW are allowed.
- Connection Type: Consumers must have a connection with the Kerala State Electricity Board (KSEB) or other local distribution companies.
2. Solar System Capacity
- The capacity of the solar system should not exceed the sanctioned load or contract demand of the consumer’s existing connection.
- The maximum allowable capacity for residential and commercial consumers is 80% of their sanctioned load.
3. Billing and Settlement
- A bi-directional meter is installed to record both the energy consumed from the grid and the energy exported back to the grid.
- Consumers are billed based on net energy, which is the difference between the energy imported and exported.
- Settlement Period: Energy credits are settled on a monthly basis, and any surplus credits are carried forward to the next billing cycle.
4. Installation and Maintenance
- Consumers must bear the cost of installing the solar rooftop system.
- The maintenance of the solar system, including cleaning and system checks, is the responsibility of the consumer.
- It is recommended to use approved vendors and certified installers to ensure compliance with KSEB standards.
5. Government Incentives and Subsidies
- The Ministry of New and Renewable Energy (MNRE) offers subsidies of up to 40% for systems up to 3 kW and 20% for systems between 3 kW and 10 kW.
- Kerala also encourages the adoption of solar systems by offering incentives for the installation of rooftop solar systems.
Benefits of Net Metering in Kerala
1. Reduction in Electricity Bills
By generating their own electricity, consumers can reduce their dependency on the grid. Any surplus energy exported to the grid earns credits that reduce future electricity bills, resulting in substantial savings.
2. Environmental Benefits
Net metering promotes the use of solar energy, a clean and renewable energy source, which helps reduce the state’s carbon footprint. By adopting solar power, Kerala can decrease its reliance on non-renewable energy sources like coal and natural gas.
3. Energy Independence
Solar energy allows consumers to be more energy-independent, reducing the risks associated with grid power shortages and rising electricity costs.
4. Financial Returns
The payback period for a solar system typically ranges between 5 to 8 years, after which the energy savings essentially provide free electricity for the remainder of the system’s lifespan, which can be 20-25 years.
