Electricity usage hit a new high at 27,639.3 megawatts on Wednesday night astemperatures soared across the nation.
Soonchai Kumnoonsate, governor of the Electricity Generating Authority of Thailand (Egat), said the new peak was recorded at 8.21pm.
Usage topped the previous record of 27,345.8 megawatts set on June 11.
He said the peak occurred at night as Wednesday was a national holiday, so demandspiked among both households and service providers, such as hotels and restaurants.
Mr Soonchai predicted daily electricity consumption could hit another new peak this year, spurred by daytime demand from industry, services and households.
The Egat governor assured the public that the state enterprise can meet powerdemands, but he urged people to help lower the load between March 20 and May 20 by keeping air conditioners clean, setting thermostats at 26C, turning off unnecessary lights, and switching to power-saving electrical appliances.
Meanwhile, the Thai Meteorological Department says there won't be relief from the heat any time soon. High temperatures for the next week throughout the country will be near or above 40 degrees except for the South. Fortunately winds will be rather strong, gusting to 25km/hour or more in some places.
