Texas: Data Center Growth Threatens the Network

A Surge in Energy Demand in Texas

Electricity demand in Texas is set to experience a dramatic increase, with forecasts indicating a quadrupling by 2032. This surge is primarily driven by the proliferation of data centers seeking to connect to the state's electrical grid. As a result, Texas could surpass Virginia as the global capital of data centers by 2030.

Last week, the Electric Reliability Council of Texas (ERCOT), the organization responsible for managing the Texas electrical grid, informed regulators that electricity demand is on track to quadruple by 2032. This increase is attributed to an unprecedented growth in large data center projects seeking to connect to the grid.

Pressure on Electrical Infrastructure

Current infrastructure, including power plants and transmission lines, is insufficient to meet this explosion in demand. Consequently, data centers sometimes have to wait several years to secure an electrical connection. Some data center developers in Texas have abandoned the idea of connecting to the grid and are building their own on-site power plants, known as "behind-the-meter." Most of these projects, such as Oracle's and OpenAI's Stargate data centers in Abilene and Shackelford County, utilize natural gas.

A National Trend

This phenomenon is not limited to Texas. The Midcontinent Independent System Operator (MISO), which oversees the electrical grid for 15 states in the Midwest, South, and Mountain West, also anticipates a 35% increase in demand by 2035, primarily due to data centers. This growth is particularly pronounced in Michigan, Indiana, and Illinois, where large projects from companies such as Amazon, Google, Microsoft, Meta, OpenAI, and Oracle are underway.

MISO has indicated that demand growth is concentrated in its central region, which includes Michigan, Indiana, and Illinois. These three states are home to massive data center projects from companies like Amazon, Google, Microsoft, Meta, OpenAI, and Oracle. This 35% increase represents a historic rise for regional network operators, although it is far less extreme than the increase Texas is facing.

Uncertainties and Possible Adjustments

Despite these forecasts, ERCOT has expressed doubts about the realization of this anticipated growth and is considering consulting regulators to adjust these projections. Additionally, some data center projects may not come to fruition due to difficulties in securing funding for their construction. It is possible that not all data centers that have requested connections to the grid in Texas will ultimately be built, and the forecast of quadrupling demand in Texas may not materialize.
