Karnataka solar rooftop PV regulation

RooftopElectricity markets have always witnessed a tussle between the utilities and the regulators, Karnataka state is no different. The electricity regulator has always been among the first in the country in implementing progressive policies in the Renewable Energy (RE) sector. However, the progress of all the plans has been disheartening and in most cases it is due to lack of co-operation from the utility in the state. A case in point is the solar rooftop projects, in spite of having the highest Feed-in Tariff (FiT) of ₹ 9.56/kWh in the country in 2013, there was a lack of adoption for well over a year. The reason, Distribution Companies (DISCOMs) came up with an implementation plan nearly a year after the order.

Karnataka Electricity Regulatory Commission (KERC) has recently drafted a regulation to address the concerns of domestic residents living in apartment complexes with shared roofs and electrical connections. The proposed regulation intends to offer existing solar rooftop owners in shared roofs an option to increase their capacity and also new residents who wish to install a bigger system by aggregating the contract demand of multiple households in the building.

Proposed Regulations

The proposed regulation aims to fill all the gaps existing in the current system which hinders adoption of solar rooftop system in residential complexes. The proposed tariff at Average Pooled Power Purchase cost (APPC) which is currently at ₹ 3.97/kWh for BESCOM will raise eyebrows considering the FiT is at ₹ 7.08/kWh for domestic consumers.

Will the regulations have a positive impact?

  • The regulation is likely to have a positive impact because it removes the regulatory hurdle currently preventing residential complexes in implementing the system.
  • Residential complexes tend to install solar as a way to reduce their energy bills and hence the type of metering or tariffs wouldn’t matter much.
  • The regulation would however impact early adopters who will have to surrender their individual Power Purchase Agreements (PPA) if the complex as a whole is going for a bigger system in the common roof.

Overall, the regulation is definitely a good step but I believe there are technical challenges like metering involved in the implementation phase which only the DISCOMs can solve. I had a conversation with a regulator in KERC prior to the drafting of this regulation discussing issues related to solar rooftop in the state. He clearly admitted that at their level they can only bring in the best-fit regulation considering all stakeholders in mind but the final implementation is out of their purview. The comments to this draft regulation are open till 5th July post that there could be a revised regulation coming up.
