The US Department of Energy (DOE) began the week following Independence Day with a bang, releasing a report that the status quo is unsustainable for the US electric grid.
According to DOE, blackout risks in 2030 could be 100 times higher if the US keeps shutting down conventional power plants.
According to DOE’s analysis, the grid will not be able to sustain an estimated 104GW of baseload generation retirements by 2030 and isn’t prepared to meet the growth in electricity demand driven by data centers and artificial intelligence (AI).
The DOE expects an additional 100GW of new peak-hour supply to be needed by then; half of that growth is directly attributable to data centers.
The United States has more than 1,500GW of generation capacity waiting in interconnection queues and more than enough planned to satisfy 2030 projections in some regions, but roughly 95% of that is renewable energy. The DOE under Trump argues that intermittent energy sources like wind and solar will not meet reliability demands, and recent legislation signed by the President reflects this belief.

“Modeling shows annual outage hours could increase from single digits today to more than 800 hours per year,” the Resource Adequacy Report contends. Such a surge would leave millions of households and businesses vulnerable. We must renew a focus on firm generation and continue to reverse radical green ideology in order to address this risk.”
The report further argues that traditional reliability metrics, like the 1-in-10-year loss of load expectation, don’t account for modern risks like weather variability, intermittent generation and interregional dependencies. DOE introduces new metrics like Normalized Unserved Energy (NUSE) and Loss of Load Hours (LOLH).
The DOE noted that even without retirements, risks remain. In a hypothetical scenario where none of the plants scheduled to retire actually do, the blackout risk still rises 34-fold due to load growth alone, highlighting the urgent need for firm capacity additions.
