A high-voltage electricity cable linking Scotland and North Wales could be laid across the length of Wirral.
The 400km (249-mile) cable would run from Ayrshire on the west coast of Scotland through the Irish Sea to the tip of the Wirral Peninsula.
It would then travel across Wirral, taking electricity to Connah's Quay in North Wales.
Environmental campaigners are concerned about the plan, which is being floated by National Grid and Scottish Power.
The companies are holding public consultation events throughout February.
They say the new circuit will transfer large volumes of energy from Scotland directly into England and Wales and are working closely with the local councils, nature conservation agencies, local environmental groups and landowners to minimise the effect on the environment.
It is understood that the cable could not be run beneath the Dee Estuary, which is home to thousands of wader birds and a designated Special Area of Conservation.
Instead it is expected to enter the peninsula on the coastline between Leasowe and Moreton.
Andy Hiorns, project director said: "This is an incredibly important project for the UK - it will help the country to meet its climate change commitments."
He added: "We are committed to working with local communities. We are keen to speak to as many people as we can and hear as many views as possible."
Ian Lewis, Conservative councillor for Moreton and Leasowe, has arranged to meet with representatives from the National Grid to discuss the plans.
"I'm pleased that the power they are producing in Scotland through wind and water is replacing the demand that we have on coal and oil-fired power stations," he said.
"My concern locally is that any work that they do must not damage the environment, either immediately here at the coast at Leasowe, which is a site of special scientific interest and a green flag coastal park, and also the disruption to Wirral residents when they start to dig up the length of the borough."
