Climate campaigners have been removed by police after scaling a 131ft (40m) lighting tower at a power station.
Didcot Power Station provides electricity for two million homes
Three climbers from Reclaim Power put up a 30ft (9m) orange and black banner, which read "Climate Crime", at Didcot power station early on Tuesday.
The aim of the demonstration was to highlight the role of coal-fired power stations in climate change.
Npower, which runs the Oxfordshire power station, said supplies were not affected by the action.
Thames Valley Police said no damage was caused and the five protesters who turned up co-operated with officers. No arrests were made.
Campaigners remained on the tower for about three hours before being escorted from the premises by police.
James Laverty, spokesman for Reclaim Power, told the BBC News website: "We feel the morning went very successfully.
"We wanted to point out that coal fired power stations are very bad for the environment and one of the biggest producers of carbon dioxide.
"If we're really serious about stopping climate chaos then we need to be seeking to shut them down permanently and replacing them with viable alternatives."
Neil Scot, production manager at Npower, said: "When they climbed a... lighting tower our primary concern was for their safety."
The action by Reclaim Power at Didcot power station is part of a series of protests across the country.
