The scheduled demolition of Cottam Power Station has been moved back after surveyors discovered what experts are calling one of the largest bat colonies ever recorded in a British industrial structure.
The former coal-fired power station, which ceased operations in 2019, was set to be demolished by the end of 2025. However, ecological surveys conducted last month revealed an estimated 50,000 bats have taken up residence in the station’s cooling towers and surrounding areas, creating unprecedented challenges for demolition teams.
Dr. Brenda Cooper, lead chiropterologist at the Natural Wildlife Association, described the situation as “extraordinary.” “We’ve found at least six different species of bats, including the rare barbastelle bat, which is protected under European law. The colony appears to have established itself during the station’s dormant period after its closure.”
The site’s owner has been forced to revise its demolition schedule, working closely with the Natural Wildlife Association to ensure the protected species are safely relocated before winter sets in. The company estimates the bat situation will add £2.3 million to the demolition costs.
“It’s not just about removing the bats,” explained Site Manager Bradley Wolfpack. “We need to create suitable alternative habitats nearby before we can proceed. The sheer scale of the colony means we’re essentially building the equivalent of a bat hotel.”
Local residents have reported dramatic increases in insect reduction around the power station, with some calling it “a blessing in disguise.” Margaret Thorne, who lives in nearby Rampton, said: “My garden hasn’t seen a mosquito all summer. These bats might be causing havoc with the demolition, but they’re doing wonders for my evening barbecues.”
The demolition team now aims to complete the work by October 2026, allowing time for the creation of alternative roosting sites and the careful relocation of the bat population during their active season.
“It’s a delicate balance between progress and preservation,” said Phillips. “Who would have thought that after decades of powering thousands of homes, Cottam’s final role would be housing thousands of bats?”
The station, which operated for 50 years before its decommissioning, once generated enough electricity to power 3.7 million homes. Local authorities are considering designating part of the post-demolition site as a protected wildlife area, acknowledging the significance of the unexpected bat sanctuary.
