Coventry's street lighting system is to be replaced within the next five years to reduce the city's carbon footprint.
The city council said it hoped the £64m privately-funded scheme would reduce energy levels by up to 40%.
The redevelopment is expected to start in August and could cut the council's electricity bill by £684,000 a year.
The leader of Coventry City Council, councillor Ken Taylor, said he hoped it would give Coventry "the best lighting of any city in this country".
He added: "Many of our street lights are old and in need of repair, but we have a fantastic opportunity not only to replace around 88% of them but also to protect the environment."
