Midlothian Electricity Rates

Midlothian is part of the deregulated ERCOT electricity market, which means you get to choose your retail electric provider (REP) from dozens of licensed companies competing for your business. Each REP offers different rates, contract lengths, and plan features — from budget-friendly fixed-rate plans to 100% renewable options. Oncor Electric Delivery owns the poles, wires, and meters throughout Midlothian and Ellis County, and delivers power to your home regardless of which REP you select. Your REP handles your bill and customer service, while Oncor handles infrastructure maintenance and outage restoration. The Public Utility Commission of Texas (PUCT) oversees the entire market and licenses all providers, ensuring every REP on this page is a legitimate, regulated option.

As of March 30, 2026 @ 8:50 AM CT, the cheapest Midlothian electricity rate is 8.2¢/kWh at 1,000 kWh usage, offered by Gexa Energy (Gexa Eco Saver Plus 12). The average rate across all 195 available plans is 13.78¢/kWh. Midlothian is served by Oncor, the largest TDU in Texas, which means residents have access to one of the broadest selections of competitive plans in the state. Rates are updated multiple times daily to reflect real-time market conditions.

At the current average rate of 13.78¢/kWh, a Midlothian home using 1,000 kWh/month would pay about $138/month. Most Midlothian homes use between 1,000 and 1,300 kWh per month, though newer homes in master-planned communities like Hawkins Meadow and AustinWaters may trend slightly lower due to modern insulation and HVAC systems. Summer bills can climb significantly — North Texas heat pushes usage to 1,500–2,000+ kWh for many households, especially in larger single-family homes that are common in Midlothian’s newer subdivisions.

Midlothian earned the nickname “Cement Capital of Texas” because it is home to three major cement manufacturing plants: TXI (now part of Martin Marietta Materials), Ash Grove Cement (owned by CRH), and Holcim. The area’s abundant limestone deposits made it an ideal location for cement production, and together these facilities produce a significant share of the Portland cement used across Texas and the Southern United States. The cement industry has been the backbone of Midlothian’s economy for decades, providing hundreds of well-paying jobs and contributing substantially to the local tax base. Even as the city transitions into a booming DFW suburb with new residential developments, the cement plants remain a defining part of Midlothian’s identity and economy.

Midlothian’s cement plants and steel operations are among the largest electricity consumers in Ellis County, but residential customers are not directly affected because the deregulated market separates industrial and residential pricing and procurement. The industrial presence has, however, contributed to robust grid infrastructure in the Oncor territory serving Midlothian — heavy industrial loads require reliable transmission and distribution capacity that also benefits residential neighborhoods. Additionally, the strong tax revenue generated by these industrial operations helps fund Midlothian ISD and municipal services, indirectly benefiting the community. Residential electricity rates in Midlothian are determined by the same competitive market forces as any other Oncor-served city in the DFW area.

Oncor Electric Delivery is the transmission and distribution utility (TDU) serving Midlothian and virtually all of Ellis County. Oncor owns and maintains the power lines, transformers, meters, and other infrastructure that physically deliver electricity to your home. You can reach Oncor at 888-313-4747 or visit oncor.com for outage reporting, meter issues, and service inquiries. Regardless of which retail electricity provider you choose for billing and rates, Oncor is the company that keeps the lights on. Oncor is the largest TDU in Texas, serving more than 10 million customers across the state, so Midlothian residents benefit from the scale and reliability of a major utility operator.

For most Midlothian residents, a fixed-rate plan is the safer and smarter choice. North Texas summers regularly push temperatures above 100°F, which means you’ll use the most electricity exactly when wholesale prices spike — a variable-rate plan can expose you to bills of $250–$400 during peak summer months on a home that costs $100 to power in spring. Fixed-rate plans lock your per-kWh energy charge for the full contract term, typically 12–36 months, protecting you from seasonal price swings. The trade-off is an early-termination fee (usually $150–$200) if you cancel before the term ends. Variable-rate plans make sense only if you’re staying temporarily or closely monitoring ERCOT wholesale market conditions.

Switching providers in Midlothian is straightforward and takes about five minutes. Pick your new plan on this page and sign up online or by phone. Your new REP files a switch request with ERCOT (the Electric Reliability Council of Texas) and Oncor, and the changeover happens on your next meter-read date — typically within 1–3 business days. There is absolutely no service interruption: no one visits your home, no one touches your meter, and the lights stay on the entire time. If you’re leaving a current contract early, factor in any early-termination fee, though you can switch penalty-free during the final 14 days of your existing contract.

Yes — and they’re often priced competitively with conventional plans. Green Mountain Energy, Chariot Energy, and Gexa Energy all offer 100% renewable electricity plans in Midlothian’s Oncor territory, backed by Texas wind and solar renewable energy credits (RECs). Texas is the nation’s largest producer of wind energy and a rapidly growing solar market, which means green plans are no longer the premium product they once were. In some months, the cheapest available plan in Midlothian is a 100% renewable option. If you have rooftop solar panels, several providers including Chariot Energy, TXU, and Rhythm offer solar buyback programs that credit you for excess generation exported back to the grid.

Texas law (PUCT Substantive Rule §25.475) requires your retail electricity provider to send a written Contract Expiration Notice at least 30 days (and no more than 45 days) before your plan expires. If you do nothing, you’ll automatically roll onto a month-to-month variable rate that is almost always significantly more expensive — often 15–20+ ¢/kWh, far above the competitive fixed rates available on this page. Set a calendar reminder about six weeks before your contract end date, shop for new Midlothian plans here, and lock in a new rate while your old plan is still active. You won’t pay an early-termination fee during the final 14 days of your existing contract, giving you a penalty-free window to switch.

Midlothian is one of the fastest-growing cities in the DFW metroplex, with its population surging past 35,000 as master-planned communities like Hawkins Meadow, Crystal Creek, and AustinWaters attract thousands of new families. Midlothian ISD’s strong reputation, combined with the city’s relatively affordable land along US-287 and US-67, has made it a magnet for suburban growth from both Dallas and Waxahachie directions. This rapid expansion has increased residential electricity demand, but Oncor has been actively expanding transmission and distribution infrastructure to keep pace. More residents also means more retail electricity providers competing for Midlothian customers, which generally drives better rates and more diverse plan options for consumers. The mix of Midlothian’s legacy industrial base and new suburban neighborhoods creates a uniquely balanced electricity demand profile for the area.

Midlothian commercial electricity rates are custom-quoted based on your business’s usage profile, demand patterns, and contract terms. Unlike residential plans with published per-kWh rates at standard usage tiers, commercial pricing includes energy charges plus demand charges based on your peak kilowatt draw. This matters especially in Midlothian, where the business landscape ranges from energy-intensive industrial suppliers and cement-related operations to the growing corridor of restaurants, retail shops, and professional services along US-287. Midlothian businesses that shop providers rather than accepting default utility rates typically save 15–30% on their electricity costs, with savings scaling alongside usage.
