Yes, just a really short contribution.
According to the National Electric Reliability Corporation, between now and 2022—with most of it happening by 2017—71 gigawatts of fossil fuel power generation will be retired in the U.S. That's a ton of energy. and there's going to be a replacement form for it. Some of it will be natural gas—a good chunk of it will be—but a lot of it won't be.
If we step into the forge with the readily available energy and we can get permission to export our clean electricity under the renewable portfolio standards—which the majority of states have, but they currently do not include hydro imports under the renewable portfolio standard. If we could get that changed in the next few years, there's a huge opportunity for us to bridge that gap that will be left when the fossil fuel assets are retired. There's a whole raft of EPA regulations coming out around coal that's going to cause more to retire, so the 71 gigawatts by 2022 is viewed as a conservative estimate.
