Electricity prices are set to increase as the power tariff rises, mainly resulting from the impact of the Israel-US war on Iran. Households and businesses are being asked to choose between three different tariff rates -- 3.95, 4.08 and 4.59 baht per kilowatt-hour (unit) -- on the ERC website from March 25-31. "We will announce the new tariff rate on April 1," said Poonpat Leesombatpiboon, secretary-general of the ERC. The tariff consists of a base rate of 3.78 baht and a fuel tariff (Ft), which adjusts for fuel costs and policy-related expenses. According to the regulator, the cheapest option is a power tariff of 3.95 baht a unit, an increase of 2%.
