Central Maine Power Co.’s $1.4 billion transmission system upgrade isn’t designed to handle the power that can be made available at times from new and existing alternative energy plants.
This story is increasingly common. Renewable energy is widely distributed and can flucuate instantly in amounts of power generation, something traditional grids aren’t designed to handle. Even with the upgrade, the new Maine grid will have stability problems at an interconnection where it sends large amounts of power south to other New England states.
“One of the effects could be that Connecticut would go dark,” said Tony Buxton, a Portland lawyer who represents large energy users in Maine.
