One of the most interesting parts of Amber Rudd's speech yesterday was the suggestion that renewables operators must pay for all the extra costs they bring to the system. Most people seem to be concluding that this means some kind of a tax on renewables.
This is all well and good, but the devil is in the details. So when the minister says:
In the same way generators should pay the cost of pollution, we also want intermittent generators to be responsible for the pressures they add to the system when the wind does not blow or the sun does not shine.
Does she mean that the rest of the grid is going to have to pick up the tab for connecting all those hundreds of wind turbines to the grid?
