Households to sell solar power

Yuthana Praiwan

The government will end the decade-long restriction on households and commercial buildings selling power generated by their solar rooftops to state utilities in the fourth quarter of the year.

Deregulation will open the door for detached houses, warehouses, factories and offices to sell their leftover capacity to the Electricity Generating Authority of Thailand (Egat).

The buying rate is being fixed at below 2.6 baht per kilowatt-hour, according to the Energy Ministry.

At present, private actors are allowed to sell power to Egat through auctions under the small power producer (SPP) or very small power producer (VSPP) project.

Energy Minister Anantaporn Karnchanarat said the government is considering granting licences to residents and building owners.

The total capacity to be allowed, however, has yet to be finalised.

The licences and deregulation come after the previous solar deregulation project was scrapped when the military government came into power.

Gen Anantaporn said this could be another opportunity to let other solar-related businesses grow.

Initially, the purchasing rate that the state utilities will pay for surplus solar power from residents will be below 2.6 baht per kilowatt-hour, cheaper than the fossil-based power Egat sells to consumers, which is about four baht per kilowatt-hour, he said.

The Department of Alternative Energy Development and Efficiency has been appointed to set up details and conditions for granting licences and the process to buy back power from the residents.

Gen Anantaporn said policymakers need to deliberate over details because there are several types of solar rooftop and different technologies -- resulting in different sizes of solar rooftop projects at different power costs -- before figuring out the regulation and licensing process.

Prasert Sinsukprasert, deputy director-general of the Energy Policy and Planning Office, said the regulations should be approved by October.

The Energy Ministry had assigned Chulalongkorn University's Energy Research Institute (ERI) the task of conducting a feasibility study of the plan. The ERI found that the deregulation of solar rooftops and letting people generate their own power would create minimal revenue losses for state utilities.

ERI researcher Sopitsuda Tongsopit said solar rooftops are expected to have a minimal effect on state utilities in generating backup power, as total power-generating capacity for solar remains small compared with the overall amount of electricity in the country's power supply system.

Thailand has 2,990 megawatts of solar power installed. Some 2,960MW, as of July, is from solar farms, while an additional 130MW is from rooftops.
