After a 4 year postponement, Thai energy policymakers have finally given the ‘go-ahead’ to start buying solar power produced by private buildings and households.
The surplus solar power generated by private buildings and households (that are accepted by the programme) will be able to be sold to the state, and be fed back into the grid.
Energy Minister Siri Jirapongphan said the Department of Alternative Energy Development and Efficiency is carrying out studies to outline the investment conditions, which are expected to be concluded this year. He said there is no solid time frame yet because details such as business model, investment budget, power tariff, net metering system, supporting region and capacity from each building are still under development.
The power tariff to sell back to the state will be around 2.44 baht per kilowatt-hour (kw/h).
The cost to develop rooftop solar PV panels has seen to be on the decline.
This programme will allow for private buildings and households to sell their power either under a business-to-business model or to sell surplus electricity wholesale to the state. “We are working to support households to participate in the power generation from their own rooftops and to receive revenue from selling the surplus electricity,” Mr Siri said.
This programme is aimed at achieving policymakers’ goal to have all types of renewable energy make up 30% of the country’s total power generation by 2036 from 10% at present.
The policymakers expect to see a decline in heavy dependence on fossil-based power in the long run. Fossil fuels make up 85% of national power.
Mr Siri said the programme may be accelerated to increase the proportion of renewable energy and meet the target sooner than projected. The rooftop programme was launched for the first time in 2013 with a total quota of 200MW. Bangkok, Nonthaburi and Samut Prakan were allocated 80MW of the total, equally distributed between private buildings and households. At the time, the power tariff was set at 6.10-6.96 baht per kilowatt-hour, higher than for the upcoming programme.
Solar rooftop owners will operate as independent power suppliers (IPSs). The Energy Regulatory Commission reported that registered IPSs in Thailand have a combined capacity of 2,600MW and more new IPSs are being launched each month with an average capacity of 4-5MW.
IPS capacity will account for 6.5% of the total power production system in Thailand.
