What Is A Black Start Of The Power Grid? — Practical Engineering

This is a fun brief primer into how a large grid recovers from a total outage.

It’s just not feasible to maintain that amount of standby generation capacity at every power plant. Instead, we designate black start sources that can either spin up without support using batteries and standby devices or that can remain energized without a connection to the rest of the grid. Obviously, these blackstart power plants are more expensive to build and maintain, so we only have so many of them spread across each grid.

These "black start" power stations that help the rest of the grid get back is pretty cool. Overall this whole thing reminds me a bit of the complexity of starting a data center if everything is shutdown. Complex systems, it seems, always require a key amount of choreography in order to get themselves back up and running.
