Nineteen projects were announced as winners in the government's CIS announcement yesterday - including seven standalone solar farms and six standalone wind farms.
Semi-scheduled generators shouldn't treat self-forecasts as commercial parameters. The regulator holds significant concerns with the biasing of self-forecasts for commercial benefit.
