Electricity was cut off in a tambon on Saturday morning when a trailer truck crashed onto its side and knocked down nine power poles in Ayutthaya's Nakhon Luang district.
Police said the accident happened on the Tha Rua-West Ayutthaya road in front of Wat Bandai in Tambon Bang Rakam.
The accident caused a blackout to Tambon Bang Rakam and blocked the road to the temple.
The truck was driven by Niran Juwanna, 48, who was injured and taken to hospital.
Ayutthaya electricity officials said it would take half a day to clear the fallen power poles and instal new ones to resume the electricity supply.
