There is a very fine nuance, in our opinion, to the difference between risk and cost-benefit. We have a very professional financial manager in the city, and he said that we had to make a utility-grade return on investment. We made these investments. The system is going to cost the city about $30 million.
We talk about some risk, and a lot of it has to do with timing. There may be some technology risks. We adopted a technology that had slightly lower risks. The risk for us was that if we invested in the capital, built this energy centre, and put the pipe in the ground, but we didn't have customers hooked up and generating revenue.... You can do a projection that says this development will come online three years out, or that development will come online six years out, but especially in those early years, if you don't have as much customer load as you anticipated, that's where the risk comes in, from our perspective.
