Northampton Borough Council is to receive an award in recognition of its switch to green electricity.
The government has set targets that require at least 15% of all UK electricity consumption to come from renewable sources by 2015.
All of the council's major offices and car parks are now being supplied with green electricity.
A council spokesman said he hopes companies across the town will follow its lead.
The council's sustainable development chairman, Michael Hill, said: "The use of green electricity is just one way in which we can practice sustainable development and I hope companies throughout Northampton will follow the borough council's lead in this important area."
The award will be presented at the Guildhall on 14 December.
