A £2 million project to upgrade the power network in Lancaster, Morecambe and the surrounding areas is being carried out by Electricity North West.
The project will involve the upgrade of 7km of underground power cables, which have been in place since the 1950s, with new updated electricity cables.
Daniel Garner, transmission north manager for Electricity North West, said: "We take great pride in powering the lives of more than 22,000 customers in Lancaster and Morecambe and now is the time to make sure everyone continues to receive the power they need when they need it for another 60 years and more.
This investment in the city's electricity infrastructure follows the £2.6m flood defence work at Caton Road substation completed by Electricity North West. The work has lifted key equipment three metres from the ground to ensure it would not be affected by flood water following damage caused when the River Lune burst its banks during Storm Desmond in December 2015.
