Thank you for the question.
Those kinds of determinations are made in each of the jurisdictions. Each jurisdiction has a different approach to it. Some provinces have integrated resource-planning processes. Some provinces have an independent system operator that is charged with undertaking those sorts of studies.
Yes, on the life and the life cycle of some of these generation sources, we don't know yet and, indeed, we're going to have to see. We're used to building technology that lasts for decades and decades. In the case of some of our hydro plants, we have hydro plants that were built in the late 1800s on the Niagara River that are still operational today. Now, they've been upgraded, and they continue to be upgraded on an ongoing basis, but we don't know at this stage if that is going to be the future of wind generation and if what occurs in wind generation will be a changing out of some of the parts.
The same is true of other new generation sources as well. We just don't know yet. We don't have enough experience, but there are responsibilities in every jurisdiction to undertake those studies and make those determinations.
