Grid Resilience is top of mind for utility companies, the DOE, and the general public these days, as we see increasingly destructive storms hit the United States. Over the past two years we had five major impact hurricanes (Irma, Harvey, Maria, Florence & Michael) and the consensus is that these will continue, or worsen, over the coming years due to Climate Change.
The goal of resiliency is to have the power grid for an area diversified and upgraded such that it can handle extreme demands. The DOE outlines the major concepts that underlie resilience planning as: Robustness, Resourcefulness, Rapid Recovery & Adaptability. These separate but connected aims allow the grid to both better absorb shocks and more rapidly adjust different factors to respond to risks & outages.
We got a decent look back on how upgrades and risk management planning played out in some of the storms in the past two years. I wrote an article for Oil & Energy magazine detailing each storms responses & issues, as well as more information on resiliency goals in general. You can read that article here: Hurricane Resilience
