| Work Detail |
The Karnataka Electricity Regulatory Commission (KERC) has introduced new measures to facilitate the adoption of rooftop solar photovoltaic (SRTPV) systems, aiming to streamline the installation process for consumers. As per the new rules, online applications can now be submitted for SRTPV systems with capacities up to 150 kW, including the Power Purchase Agreement (PPA). These applications will be deemed as approved, allowing consumers to begin installation work immediately.
In line with the Electricity (Rights of Consumers) Amendment Rules, 2024, issued by the Ministry of Power (MoP), Government of India, the KERC has made significant changes for SRTPV systems up to 10 kW. According to sub-rule 7A, applications for these systems, if complete, will be automatically accepted without requiring a technical feasibility study. Additionally, if the consumer needs to enhance their sanctioned load for the SRTPV system, the distribution licensee will handle the necessary adjustments.
BESCOM, the electricity distribution company in Karnataka, had approached the Commission with a request to simplify the process and encourage wider participation in the PM Surya Ghar Scheme, which promotes the installation of rooftop solar systems. During discussions with system integrators and electricity supply companies, the issue of mismatched capacities between solar modules and the applied system capacity was raised. System integrators suggested that a capacity tolerance of up to 10% should be allowed for SRTPV systems up to 10 kW to address consumer concerns.
In response to these requests and to further promote the deployment of rooftop solar systems in Karnataka, the KERC has issued new guidelines. Under these guidelines, consumers wishing to install an SRTPV system up to 10 kW will be permitted to enhance their sanctioned load automatically if it is less than the required capacity for the system. The distribution licensee will then make necessary adjustments, such as augmenting the capacity of distribution lines or transformers, in line with the relevant regulations.
However, if the consumer’s sanctioned load is increased, they will be required to pay the applicable charges, deposit additional security, and sign a power supply agreement for the additional load before the SRTPV system is commissioned. This process will follow the Conditions of Supply of Electricity to Distribution Licensees in Karnataka and other relevant regulations.
The Commission has also introduced a capacity tolerance of 10% for SRTPV systems with up to 10 kW of sanctioned load. This tolerance applies to the system’s DC capacity, allowing consumers to install systems slightly larger than their applied capacity. For example, a consumer with a 5 kW sanctioned load can install an SRTPV system with up to 5.4 kW of DC capacity, as long as the inverter’s AC capacity does not exceed 5 kW. Similarly, for a 10 kW sanctioned load, a consumer can install up to 10.8 kW of DC capacity but must ensure the inverter’s AC capacity remains at 10 kW.
These measures aim to simplify the process of adopting rooftop solar energy, ensuring greater consumer participation in the state’s renewable energy initiatives while maintaining regulatory standards. The new rules are expected to make it easier for consumers to install solar systems and contribute to Karnataka’s clean energy goals. |
