I just wanted to get back to the discussion about electrification. I'm wondering if any of the companies have done a cost-benefit analysis over a significant period looking forward, say, 30 years plus, with regard to the fuel costs and alternatives and comparing those. Initially, the barrier was the capital costs in terms of electrification, but if you look at the fuel costs going forward—I know it's hard to predict—has there been any kind of cost-benefit analysis or studies done on those?
