Abbott Orders PUCT to Cut Residential Transmission Costs by July 31 — and Make Data Centers Pay Their Own Way

What the Governor's Directive Says

According to the letter and reporting by the Texas Tribune and Houston Public Media, Abbott's directive to the PUCT and ERCOT includes two immediate orders:

• Reduce residential transmission costs: the PUCT must "initiate action to reduce residential transmission costs" by July 31, 2026.
• Data centers pay their own way: data centers connecting to the ERCOT grid must pay all costs of the power infrastructure built for their operations, so residential ratepayers bear none of it.

Both agencies must submit a joint memorandum by July 17 summarizing the steps they have taken, the limits of their current legal authority, and any new laws they would need.

"The rapid scale of data center development requires oversight to ensure everyday Texans are not burdened with the costs of infrastructure driven by data center expansion, and to ensure that as data centers interconnect to the Electric Reliability Council of Texas (ERCOT) grid, residential electric bills are not negatively affected," Abbott wrote in the letter.

Abbott also outlined legislative priorities for the 2027 session: requiring new data centers to add generation to the grid (not just demand), codifying the pay-your-own-way rule, mandating water-efficient cooling, requiring annual electricity and water usage reporting, and repealing the data-center sales tax exemption — a break the Texas Tribune reports is set to cost the state about $3.2 billion over the next two years.

Why Transmission Costs Are on Your Bill in the First Place

Every Texas electricity bill has two parts: the energy-supply charge from the retail provider you choose, and the TDU delivery charge — a regulated fee for the poles, wires, and transmission lines that move power to your home. Delivery charges are set by the PUCT, are identical for every provider in your area, and have been climbing as Texas builds out its grid.

That buildout is substantial. ERCOT stakeholders endorsed roughly $6.5 billion in new transmission projects in May 2026, on top of a $9.4 billion 765-kV transmission plan approved in late 2025 — and Oncor customers in North Texas saw delivery charges rise about $4.64 a month on June 1. A major driver is large new load: ERCOT reported that as of May, large projects asking to connect to the grid totaled 439 gigawatts of capacity — roughly five times the grid's all-time peak demand — and about 89% of those requests are data centers.

Under today's rules, much of the cost of new transmission is spread across all customers, including households. Abbott's directive aims to change who pays for the share driven by data-center growth.

What It Could Mean for Your Bill

Two important caveats. First, this is a directive to initiate action — no specific rate reduction has been set, and the industry's trade group says many members already pay full cost of service. Second, the data-center boom this directive responds to is the same demand growth that puts upward pressure on wholesale power prices, which flow into the retail rates you shop for.

The Consumer Takeaway: Control the Part of the Bill You Can

Whatever the PUCT does by July 31, TDU delivery charges will remain identical across every retail provider in your ZIP code — so they never change which plan is cheapest for you. What does change your bill is the energy-supply rate, and that depends heavily on your usage level.

Many plans are priced to look cheapest at exactly 1,000 kWh — the advertised rate — while costing meaningfully more at 800 or 1,400 kWh. With record summer demand forecast and grid costs in flux, checking your plan's real effective rate at your usage is the most reliable way to avoid overpaying.
