Govs have failed to increase renewable energy production on grid scale.
A story of diminishing returns. The more rooftop solar that goes in then the less return there is for grid scale wind and solar as they are the ones subject to curtailment of production in times of excess. Coal and gas still needed when the sun goes down at the end of the day.
The Gov is going to announce their plan to underwrite new generation using auctions and "contract for difference" by expanding the Capacity Investment Scheme.
Basically the cost of doing this is undefined because investors are guaranteed a minimum return which is the return they can get from the Government if market prices go below a level set by winning auction bids.
