Thank you, Mr. Chair.
We talked a little earlier about the longevity of projects. I don't know if you said it, but somebody said that there's a 25-year life cycle in projects and that it's at least 12 years before there's any start to the recovery of the costs.
Have you done any work on the lifespan of the various technologies in your projects? I guess this question is more for the folks who are well along in projects. Solar panels, I'm told, have to be replaced after a certain number of years. What is the lifespan of the technologies you're using in your projects?
