Electricity demand expected to increase 50% by 2050

Electricity demand in the United States will increase 2% yearly and as much as 50% by 2050, according to a study conducted by PA Consulting and released by the National Electrical Manufacturers Association (NEMA). The increase is largely driven by record growth in data centers and e-mobility.

The study, “A Reliable Grid for an Electric Future,” highlights technology and policy solutions to maintain a reliable and affordable energy system through this new age of demand growth.

It predicts that growth in electricity demand in the United States will be driven by a 300% rise in energy consumption by data centers. Also by an 9,000% increase in energy consumption required for e-mobility and charging.

Overall, electricity is projected to grow from 21% of final energy use to 32% by 2050, at which time it isestimated that:

• Electricity demand will have grown by over 50% in the U.S.
• Storage, wind, and solar generation will increase by 300%.
• Renewables are expected to exceed 50% of generation capacity in Western U.S., New York, and Southeast.

Between 2023 and 2037, 1,323 TWh of growth is predicted in the U.S as follows: 32% data centers, 24% transportation, 16% industrial, 15% residential, and 13% commercial.

Over the next 13- year period, from 2038 to 2050, NEMA predicts another 1,360 TWh of growth. But this time around, the sector with the most demand growth will be transportation, accounting for 51% of electricity demand growth, followed by industrial at 28%, residential at 11%, and commercial at 9%.

Data centers are forecast to add only 1% more load between 2038 and 2050. NEMA expects data centers to affect electricity demand for the next decade, but not in the following decade.

The AI power consumption surge will probably be at its most intense between 2025 and 2030 when AI will take up a quarter of all data center load. Some of the latest AI and machine learning applications require ten times more power than traditional computing workloads.

But the pace and scale of AI expansion, based on rates of technological advancements or shifts in IT strategies.  will vary sharply by region. In parallel, increased cloud adoption is fueling data storage and processing capabilities. This generates yet more electric load.

Consumption changes will also vary by U.S. region and across markets over time, driven primarily by data centers in the next decade and EVs in the longer term. The Mid-Atlantic and Texas will see the largest data center electricity demand growth through 2035. The Northeast and West will experience the largest electricity demand growth from EVs between 2035 through 2050.

The study identifies near-term and emerging technology solutions to make the grid more efficient: transmitting more with existing infrastructure, optimizing data center performance, enhancing grid stability through storage, and creating ways to manage peak load.

It outlines policy frameworks to meet coming demand in an all-of-the-above energy system. This encompasses comprehensive permitting reform, the securing of tax certainty, bolstering the manufacturing workforce, and alleviating critical supply chain bottlenecks.

“America’s electrical system will face dramatic changes over the next 25 years,” said Debra Phillips, President and CEO, NEMA. “As electricity demand is set to rise for the first time in decades, an all-above-approach that focuses on investing in innovative technologies and prioritizing policy and regulatory certainty to create the reliable and affordable energy system of the future.”
