Hundreds of people in Portsmouth and the surrounding area joined protests last Saturday over the Aquind cable project.
Aquind Ltd wants to lay a cable between Lovedean in Hampshire and Normandy in France that would run through Portsmouth.
Protesters said its installation could destroy allotments, wildlife habitats and cause traffic disruption.
There is a good case for the inter-connector cable. It could be a part of upgrading the national grid and sharing electricity produced from renewable sources.
But there is no justification for a private company to make obscene profits at the expense of the local communities and the environment.
