Under a new UK energy department plan to cut UK power consumption, British households might be paying out millions of pounds in energy bills to provide supermarkets and airports with free LED lighting, according to a Telegraph report.

The country’s energy secretary Ed Davey recently announced a £20 million (US $ 34.20 million) taxpayer cash for trail scheme to provide businesses with funding to implement energy efficiency upgrades including replacing conventional lighting with LED bulbs.

Firms could compete for funding in a reverse auction and bid for the entire installation work to be covered or partially subsidized, which should result in cheaper energy bills, said Davey.

More than 300 organizations including “hospitals, airports and supermarket chains” have already express interest in the auction, the Department of Energy and Climate Change (DECC) said.

The funds will go to organizations that could not implement the LED makeovers without upfront funding, said DECC.
