Data centers are required to provide their own electricity supply... or cease operations

Data Centers and the U.S. Power Grid: A Growing Challenge

Major technology companies are seeking massive amounts of electricity—measured in hundreds of gigawatts—to power their expanding data centers across the United States. However, the nation's aging electrical grid and slow-paced infrastructure upgrades are struggling to keep up with this surge in demand. As a result, grid operators are presenting alternative solutions to these tech giants eager to connect their new facilities.

Emerging Solutions: Self-Supplied Power and Conditional Access

One increasingly popular approach is for companies to supply their own electricity, a trend expected to gain momentum. In several regions, grid authorities are advising tech firms to pair their data center projects with dedicated power generation to meet their energy needs.

Another option involves granting data centers priority access to the grid, but with a significant condition: during periods of peak demand that threaten grid stability, these facilities must agree to temporarily disconnect and rely on backup generators. This arrangement aims to prevent blackouts but raises concerns among operators.

Industry Pushback and Reliability Concerns

According to The Wall Street Journal, data center developers are resisting these proposals. They argue that relying on diesel generators could breach environmental regulations in certain areas. Moreover, uninterrupted power is critical for data centers, which support essential services in sectors like finance and healthcare.

“A reliable power grid is essential for data centers, which depend on consistent, uninterrupted power to support critical operations,” stated the Data Center Coalition, as reported by the Journal.

These debates are intensifying as grid operators such as PJM Interconnection propose that data centers either bring their own power generation or accept the possibility of being disconnected during high-demand periods to safeguard grid reliability.

Regional Hotspots and Capacity Strains

PJM Interconnection manages electricity flow across parts of states including Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and the District of Columbia. Many of these areas, along with Texas (served by ERCOT), have seen a rapid increase in data center construction.

The competition for electricity is intensifying, as the projected energy needs of planned data centers far exceed what the current grid can provide. This highlights that electricity supply is now the primary bottleneck for the ongoing boom in artificial intelligence and data center development.

High Stakes and New Connection Models

“It’s a high-stakes fight, because hundreds of billions or even trillions of dollars in investments are at risk,” Michael Webber, an engineering professor at the University of Texas at Austin, told the Journal.

While tech companies are reluctant to accept disconnections during peak demand, they may have little choice if they want to expedite their grid connections. Some grid operators, like the Southwest Power Pool, are introducing “conditional” connections—allowing data centers to connect sooner, provided they agree to be cut off during extreme demand events.

“Some may want to do that. Others may not,” said Antoine Lucas, chief operating officer of SPP, in comments to the Journal.

In Texas, ERCOT is also considering faster grid access for large electricity users who commit to reducing their consumption during certain grid conditions, according to the Texas Tribune.

ERCOT is currently overwhelmed with requests for large-scale grid connections, totaling over 205 gigawatts—nearly four times the 56 gigawatts requested a year earlier. Of these, more than 70% come from data centers, with another 10% from cryptocurrency mining operations.

The Rise of “Bring Your Own Generation”

Supplying their own power is becoming the norm for data center developers seeking reliable and speedy grid connections. John Ketchum, CEO of NextEra Energy, explained during an October earnings call that securing a grid connection often requires companies to provide their own generation capacity.

“To get a load interconnect and draw power from the grid, many utilities now require you to bring your own generation,” Ketchum said.

NextEra Energy emphasized at a recent investor conference that the market for large electricity loads is rapidly evolving, with self-supplied power playing a central role.

Potential Power Shortages Ahead

At the current pace of connection requests and grid expansion, the U.S. could face significant electricity shortages by 2030, warned Samantha Dart, co-head of global commodities research at Goldman Sachs, during a recent conference.

Goldman Sachs analysts noted in an October report that the growth in data center electricity demand alone could boost overall U.S. power demand growth to 2.6% by 2030—the fastest rate since the 1990s.

“We aren’t adding enough capacity,” Dart cautioned at the Goldman Sachs Energy, CleanTech and Utilities Conference in Miami, adding that failure to address this issue could put the U.S. at a disadvantage in the global AI race.
