Mr. Fintan Slye:

We keep up to date with technology at all times. As the Deputy and others have pointed out, we were the people who developed and implemented the east-west interconnector, one of the best examples of modern HVDC technology anywhere in the world. We are intimately familiar with its capabilities and what it can be used for. Because we deliver it, we are completely comfortable operating and using it in the right circumstances. Notwithstanding that, we also went out to international consultants to update the cost information. In fact we have in-house some of the foremost experts, the people who are most familiar with modern HVDC technology. We are at the edge of that technology and we understand it. As I said earlier in response to a question, as we progress projects we always look for the best and most up-to-date information, including updated forecasts of demand and economic growth, changes in project needs and what is happening on the system, and also progress in technology. At each stage we examine what has changed in terms of the project, the need or the technology, and we continually keep these things under review.
