There's been a lot of talk about SMR's over the years, it's nice to see one finally being built.

Even if it comes in over budget, getting the first one done will be a great learning experience and could lead to figuring out how to do future ones cheaper.

Assuming it's on time, completion in 2029, connected to grid in 2030.

The small modular reactor (SMR) would provide 300 megawatts of power, enough electricity to supply about 300,000 homes, according to briefing documents from Ontario's Ministry of Energy and Mines.

300MW isn't small at all. That's half a CANDU block! I thought they would be significantly smaller and therefore not too significant for the grid until we build more units. This is the equivalent of 20-30 of the largest wind turbines available. Not sure if we have that large units installed in Canada.

It's small compared to typical nuclear reactors which are usually 1GW, and these new units use much less land space.

Edit: They're also designed to be manufactured offsite at a manufacturing facility instead of the very large ones that are built on site.
