Energy Policy Committee Approves Electricity Rate Cuts for Consumers Using Up to 500 Units with Lower Prices Guaranteed; Expands Solar Rooftop Capacity

The National Energy Policy Committee has passed two key resolutions to reduce electricity rates. On April 29, 2025, Energy Minister Eknath Proamphant and Industry Minister Weerawut Silpaacha announced the committee's decisions at Government House.

The first resolution promotes solar rooftop installation by streamlining installation procedures and reducing approval steps. Excess electricity generated will be purchased back at 2.20 baht per unit, with buyback sales beginning after June 2025. The second resolution approves new electricity rates for residential households. For the first 200 units, consumers will pay no more than 3 baht per unit. Households consuming between 200 and 500 units will use a progressive rate structure calculated as an average, resulting in lower overall bills. Those consuming no more than 500 units monthly, or paying no more than 2,200 baht per month, will benefit from the rate reduction.

More than 90 percent of Thailand's 21 million households will benefit from this policy. The Energy Ministry is coordinating with the Finance Ministry to provide loan financing for solar installations at rates lower than electricity costs. The government is also tasking the Provincial Electricity Authority and Metropolitan Electricity Authority with offering affordable solar installation services for those without upfront capital.

For installations intended for personal use only, completion is required within 7 days. For installations with electricity sell-back agreements, completion must occur within 30 days. The committee immediately approved increasing the electricity purchase capacity by 500 megawatts, with further expansion if that capacity is reached. Minister Proamphant confirmed this electricity rate will remain in effect through the end of the current government's term.
