Dr. Liam Ryan:

We are very much looking at this from the economics perspective. In the past ten years, we have pushed the boundaries of technology and the technical challenges. The next ten years will move the boundary in both the technical and economic challenges. As my colleagues have said, the market needs to evolve and change so that we do this in the most economic and efficient manner. On the 70% target, in Shaping our Electricity Future, we were clear about highlighting the market changes that need to happen.
