John, is the "Department for Business, Energy and Industrial Strategy" a government agency or a marketing firm?

The report sets out estimates of the ‘levelised cost of electricity’ (LCOE) for various forms of power generation, from wind, solar and gas CCS to unabated gas-fired power stations. A ‘levelised cost’ is the average cost of the lifetime of the plant per MWh of electricity generated. This reflects the cost of building, operating and decommissioning a generic plant for each technology.   

LCOE has its fair share of criticisms as a single point metric, and surely to get a true look at what a grid with X more solar/wind on it replacing gas should factor in other externalities-- need for storage, need for demand response, cost to pay for standby baseload, etc. But if the pure LCOE generation costs are that much lower, that leaves a lot of room to play with to accelerate even after factoring in the other costs
