As we move towards a greener grid, how do we build critical infrastructure resilience and reliability into the electric grid to secure our future?
Securing our grid is vital. Take, for example, what happened in February 2021 in Texas when the texas grid was within four minutes of completely shutting down. Many people suffered from the lack of electricity which extended for a long period of time, and unfortunately, many died. If the grid had gone down completely and Texas would have had to blackstart, or restart, the grid, it would have taken weeks. And let’s not forget the grave consequences the people of Texas and the economy of the nation as a whole would have endured.
It would have been unthinkable.
Blackstart is the process of restarting the grid when it’s gone down in its entirety. It’s a long and complicated process, and while we have exercised blackstart in the past, it hasn’t actually had to be in use in recent years. And this is an issue, as ensuring we’re prepared for a total grid shutdown is critical to our survival.
In our modern world, everything in our lives depends on electricity. With increasing climate challenges and threatening behaviors from adversary countries and terrorist groups, building resilience in this critical resource is becoming especially important. Ensuring that we will be able to blackstart the power grid when needed is essential.
Great strides have been made in restoring relatively small blacked-out regions following conventional disasters by “leaning on” electricity from outside an outage zone. But, over a large area, and certainly if an entire grid were to go down, restoration from outside would not be workable. And since we have not had a large enough disaster to require blackstart, this capability has not been seen as a critical priority.
As our power grids become greener, we need to keep in mind that resilience, including blackstart, must be built in from the beginning. Reworking facilities that are already in place would be far more expensive and difficult.

EIS Council is providing a free webinar featuring a group of international experts to discuss the issues of blackstart both in the current grid configuration and in the future green grid scenario.
Please join us and share your questions, knowledge, and ideas in the chat so we can bring this issue to the forefront. Our It Isn’t Easy Being Green webinar will take place on Thursday, November 3rd, at 11:00 a.m. Eastern time.

“No Time to Die” The Future of Our Electric World Avi Schnurr, CEO, EIS Council The human world we inhabit is electric, and the power grid is its circulatory system, bringing the nutrients and energy it needs to keep it – and all of us – alive. Yet it would take no time at all […]
Can We Build Critical Infrastructure Resilience Before It Impacts Your Business? If recent events, especially the COVID-19 pandemic, have taught us anything, it’s that the world is capable of changing rapidly and on a large scale without much warning. And doing so in ways that can have a profound impact on how people live their […]
