What $500mill gets you..
There are a few examples of Alberta project costs in the 2019 article below. Back in 2019, one million dollars would build roughly 1mw. Costs have probably come down since then but it gives you an idea of how many MW could possibly be built for $120 million (120mw) or $500 million (could be enough for the entire 500mw portfolio). https://calgaryherald.com/business/local-business/sunrise-for-albertas-solar-industry-economics-of-commercial-scale-projects-increasingly-make-sense
