Today my colleagues and I at @RockyMtnInst released a new report that lays out modern principles and recommendations for grid #resilience in an era of transformational technology change and growing security risks. rmi.org/reimagining-gr… 1/8
Two trends motivated this research. First, the increasing likelihood and impact of catastrophic risks to grid security from climate change, other natural disasters, and malicious attacks. Each has the potential to cause a wide-scale, months-long outage. 2/8
At the same time as these risks grow in likelihood and impact, power system technology is changing faster than ever. Wind, solar, batteries, internet-connected controls, and gas are quickly gaining market share and displacing legacy assets. 3/8
But because the US grid came about in the 20th century as a one-way chain from fuel to customers, our strategies for addressing resilience risks are similarly top-down and centralized, and are now at odds with a new threat environment and market-driven technology changes. 4/8
Specifically, current approaches to grid resilience tend to focus on hardening individual components of the power system, while ignoring the interdependencies that can lead to large-scale outages. 5/8
Our report explores an emerging category of distributed resilience solutions, located closer to the customer, that can not only provide better system resilience value, but often economic value during normal system operations. 6/8
We offer four principles for grid resilience that can serve as guideposts for power system investment and policy, and help distinguish modern, market-aligned resilience solutions from outdated, ineffective, and costly approaches based on legacy technologies and architecture. 7/8
US electric utilities will probably invest >$1 trillion in the power system in the 2020s. We have a pressing opportunity to spend those $ in a way that promotes resilience by design, economically and from the bottom up, and not as a cost-adding afterthought years later. 8/8
