Bad investments.
They have several winds farms in Scotland that have to shut down when they near peak production, ie favorable winds, because the government would not pay for infrastructure upgrades to support maximum output. That task was left to the wind farm owners who naturally claim they cannot afford it. The cost of wiring in such remote areas was prohibitive.
Naturally the favorable contracts forced by the governments policies pay the wind farm owners for power never created as compensation for the power that never made it to market because of the infrastructure no one wanted to pay for.
Which begs the question. Why build the farms in the first place?
I call this policy shift a wakeup call.
