Thank you so much.
We've heard a lot today about the need for certainty—being able to have a long-term view on how things are working.
Mr. Powell, I believe that, when you were speaking, you specifically referenced contracts for differences, and the value of contracts for differences in providing that certainty. As I understand it, if you had contracts for differences, the carbon price would be set and people would know the price that would be continuing—or whatever the process would be for it.
Perhaps you could talk to me a bit more about contracts for differences and why you think they are important for the regulatory certainty for clean energy.
