Can I add one last comment to that?
When you study how these systems grow, you get these opportunities like windmills in Victoria or Southeast False Creek in Vancouver. But if you study how they grow, you see that most of the growth occurs at the edges of an established utility system.
By becoming customers, if you built federal buildings that were hydronically heated, or developed a system so you could become a customer for someone else's future system, or if you established a system that in turn.... Again, the growth happens at the edges of these established nodes, so you could help all the developments around you and start connecting them up with new and existing developments. It is an important role to establish those nodes, because that's how growth occurs.
