On Monday, April 28, a widespread power outage hit Spain and Portugal. Other than our marketing guy who was on vacation in Madrid at the time claiming he “had no signal” and “couldn’t work”, this outage highlights a broader issue with renewable energy infrastructure.
The root of the problem comes from the use of green energy sources like solar and wind, that lack the built-in stabilization that traditional energy sources like coal and natural gas have. This meant that there was no safety net to stabilize the grid once a fluctuation entered the system. Thus, the automatic shutdowns were triggered, resulting in a widespread outage.
Preventing future outages will require some changes. An expensive and multi-decade integration with a fast-discharge battery system. Keeping 15-20% of the grid powered by coal or gas. Or using microgrids, like a hippie compound. No solution is perfect, but outages will continue until something changes.
Oh, and don’t think this won’t happen anywhere else. Grids that are defined by isolation (think the United Kingdom, or Australia) will be next up.
