Calgary - Lessons To Learn

In one of the previous posts I made a point which I have been trying to emphasize for quite some time already. We do not need gigantic power grids with all their complexity and stability problems. Another confirmation of it was the latest incident in Calgary where underground fire left thousands of people struggling without a power for several days, disrupting traffic and businesses and will be certainly costing many millions for the city.

What if each building had its own power generated in sufficient volume on-site? This would give each individual unit (building, facility, business operation etc.) an independence from the grid preventing such blackout incidents. It would also remove a problem of power fluctuations in the grid which is a subject of such a many problems. There is technology which makes it possible today. Note that examples of the so-called "net-zero" or even "net-positive" buildings although a move in the right direction are not totally autonomous self-sufficient systems. They are still dependent on the grid in that they draw from it when there is not enough energy produced on-site to satisfy the building's demand, while sending energy to the grid when they have excess of it (e.g. solar PV in the middle of the day during summer).

Fully autonomous building would not depend on the grid at any time! It however does not have to be completely "off-grid". On the contrary, all independent on-site generation systems should be connected in the "intelligent network" which would utilize its resources most efficiently, while never leaving any of the nodes starving without energy. Intelligent energy network built on the Systems Architecture principles of modularity, re-usability and scalability, is actually much more than what is usually known as a "smart grid" although it can certainly be considered its evolution.
