U.S. data centers projected to consume 20% of total electricity grid power by 2035, representing 4x increase from current levels.

U.S. data centers are projected to consume approximately 20% of the nation's electricity by 2035, driven by surging AI demand—a fourfold increase from current usage, according to BloombergNEF projections. This power-intensive growth is creating significant strain on regional electrical grids already dealing with connection backlogs and rising costs.

The infrastructure pressure is particularly acute in key markets. The PJM Interconnection, which spans from Virginia to Illinois, faces severe congestion, with data centers expected to represent 34% of its electricity demand. Similarly, ERCOT, the Texas grid operator, projects data center consumption to reach 22% of its generation capacity. Both regions have grappled with massive queues of connection requests from technology companies. PJM implemented a four-year pause on new applications, and while the system has since reopened, competition for available grid capacity remains fierce. This supply imbalance has driven a 76% increase in electricity prices across the PJM region over the past year.

The trend extends globally. Global data center electricity demand is estimated to grow by 1,935 terawatt-hours by 2033—nearly equivalent to India's total annual electricity consumption. This worldwide shift toward higher-capacity infrastructure could fundamentally reshape energy supply dynamics and pricing in major economies.

For investors, the critical question is how utilities and energy companies will adapt. Power generation, transmission, and grid infrastructure providers face both growth opportunities and regulatory pressures stemming from the need to upgrade aging systems. As data centers compete intensely for reliable, consistent power, grid operators' ability to manage supply while maintaining price stability will be essential to the broader energy sector's outlook.
