Over the last three years, U.S. electricity consumption has increased by about 3% annually. This puts new strains on an aging energy grid that’s ripe for modernization. Some of the increased demand is being driven by new data centers coming online, more electric vehicles on the road and the industrial reshoring trend (i.e., manufacturers bringing operations back to the U.S.). These and other factors have pushed the federal government to assess the current situation and come up with solutions.
The latest options were presented by the Department of Energy’s Office of Electricity (OE), whose Strengthening America’s Grid Supply Chain report looks at some of the key pressures on the existing grid plus new solutions for strengthening and modernizing it. It also highlights the important role of the underlying supply chain, including the transformers, circuit breakers, substation components and other grid equipment needed to make the electric grid hum.
The core supply chain challenges include dependence on imported components and materials, limited domestic production capacity and excessive customization, OE says, noting that lead times for the equipment are currently extended out one or two years. “Furthermore, these supply chain issues drive up electricity prices for American homes and businesses,” the OE adds. “Some transformers have seen four to nine times price increases in the last five years.”
The Need is Real and Growing
According to the International Energy Agency (IEA), electricity consumption in the U.S. is set to rise by close to 2% on average per year (more than twice the rate of the past decade). It also says that:
- Electricity demand is climbing, and the amount of new demand added each year through 2030 will average about 50% more than it did over the last 10 years.
- AI and data centers, advanced manufacturing, electric vehicles and space cooling are driving much of the expansion.
- Electricity consumption will grow at least 2.5 times faster than overall energy demand.
- The U.S. isn’t alone when it comes to increased energy consumption. In global advanced economies, IEA says electricity use is rising again after roughly 15 years of stagnation.
- By 2030, electricity demand is expected to outpace economic growth globally, with total suppland per-capita consumption reaching new highs in many regions.
As electricity demand driven by data centers, manufacturing and broader electrification continues to grow, utilities and grid operators will need to add generation and transmission capacity faster than they have in recent years. They'll also need stable, reliable supply chains to move the equipment, components and materials needed for construction and ongoing maintenance.
The OE’s Supply Chain Program
Knowing the importance of a strong supply chain and the related constraints, the OE has developed a $375 million domestic supply chain enhancement program that includes:
- Strengthening U.S. readiness for supply chain disruptions by promoting greater refurbishment and reuse of existing grid equipment and materials and increasing the use of alternative materials and subcomponents sourced from the U.S. to reduce the need for imports, stabilizing supply-demand mismatches.
- Maximizing the impact of investments in domestic manufacturing capacity by promoting greater standardization of grid equipment through common configurations that can streamline production, reduce lead times and lower costs through economies of scale, optimizing resources.
- Positioning the U.S. as a leader in next-generation grid power electronics like solid-state transformers, which can reduce the need for conventional equipment and materials, increase grid capacity, and ease large load integration by strengthening the domestic supplier ecosystem, growing the jobs and grid of tomorrow.
The OE’s expected outcomes include reducing imports and lead times of critical grid components by up to 10% and lowering utility spending on essential equipment by as much as 25%. PowerLine says the program is focused on prioritizing affordable, reliable and secure technologies; strengthening grid reliability through baseload and dispatchable power expansion; and streamlining permitting to accelerate energy infrastructure development.
“The idea is to achieve four critical outcomes,” the publication adds, “energy dominance (including 100 GW of capacity additions by 2030 and increased energy exports), affordability, national security and innovation.”
