Could data centers raise your electric bill? Texas lawmakers and ONCOR weigh in

Data centers are proliferating rapidly across Texas, making the state a national hub for their development, particularly in the Dallas-Fort Worth area and along the I-35 fiber optic corridor. This growth has prompted concerns about the strain on the state's power grid and potential increases in residential electricity bills. Oncor, Texas's largest utility, reported to the Texas House State Affairs Committee that it has more data center connection requests than any other utility nationwide, predicting a potential doubling of peak electricity demand within five years if infrastructure can keep pace. Brian Lloyd, Oncor's Vice President, highlighted the unprecedented scale of these requests, stating they have "overwhelmed the existing processes." While other industries like oil and gas also contribute to demand growth, the rapid construction of data centers (18 months) compared to new power plants (up to five years) creates an immediate grid strain that could drive up costs. State Representative Pat Curry emphasized the need for "guardrails" to prevent uncontrolled rate hikes, suggesting that proper planning and resource allocation by data centers are crucial. The Texas Public Utility Commission is actively developing new rules to classify data centers as their own customer category, aiming to separate their infrastructure costs from residential customers. Lawmakers are also advocating for localized decision-making and requiring data centers to prove they have secured necessary water, power, and financing before proceeding with projects. Oncor cited its South Dallas transmission project as an example where data centers could benefit ratepayers by generating more revenue than construction costs, spreading fixed costs across more users, as seen in North Dakota's electricity rate drop. Officials view this as a "generational opportunity" for Texas to invest in its power grid, ensure reliability, and stabilize rates, provided the right regulations are implemented before the end of the year.
