Grid Resiliency is a Problem, But Stockpiling Coal isn’t the Answer

According to Mark Dyson, an expert who studies grid resilience as part of the Rocky Mountain Institute’s Electricity Innovation Lab, the U.S. does face a problem with grid resiliency. Look no further than the mainstream news headlines about Puerto Rico’s lack of electricity to see the problem in living color.

However, the U.S. Department of Energy’s recently proposed rulemaking, which directs FERC to “properly value” coal and nuclear power plants for their ability to be “resilient” by having a 90-day pile of fuel onsite, totally misunderstands the problem. Check out Dyson’s comments about how to address the real problem of grid resiliency below.

So how do you, as Dyson says, take the fuel out of the equation? That’s where onsite renewable energy such as solar PV and energy storage come into play. In fact, it is these distributed energy resources (DER) that are best suited to deliver a resilient 21st century grid.
