Description (excerpt):

The issue of ‘resilience’ of the power system—including how to best define, measure, and ensure it—has
garnered substantial attention in recent months. The energy policy community turned its collective focus
to resilience issues following the devastating electric grid failures in Puerto Rico as a result of Hurricane
Maria, as well as the U.S. Department of Energy’s (DOE) September 2017 proposal of the Grid ResiliencyU
Pricing Rule. DOE submitted the proposed rulemaking to the Federal Energy Regulatory Commission (FERC) with the stated purpose of expeditiously bolstering the grid’s resilience and reliability. The proposal called for tariff changes to ensure the recovery of costs and a fair rate of return for qualifying generators with 90-day on-site fuel storage. FERC received more than 1,500 comments on the rulemaking. Many of these submissions
commented on whether the issue of resilience has been sufficiently defined.

On January 8, 2018, FERC issued a unanimous decision to end consideration of the proposed Grid Resiliency
Pricing Rule and to initiate a new proceeding to holistically examine the resilience of the bulk power
system. The commission gave RTOs and ISOs 60 days (until March 9) to respond to a series of questions
about resilience in their geographic footprint. At the close of that comment period, other interested parties
will have 30 days to issue comment. The Commission plans to review comments and decide whether additional FERC action to address grid resilience is warranted.

This primer seeks to provide a high-level introduction to the concept of power sector resilience- highlighting what research has been done on the topic as well as key areas where more work is needed. This includes a discussion of how resilience is defined and measured; what threats the power system should be resilient to; how this term is related to, but distinct from, reliability; and what organizations are working to better define and measure resilience.

All statements and/or propositions in discussion prompts are meant exclusively to stimulate discussion and do not represent the views of, its Partners, Topic Directors or Experts, nor of any individual or organization. Comments by and opinions of Expert participants are their own.
