What Southlake Residents Pay by Usage
Southlake is not a typical DFW suburb. Homes routinely exceed 4,000–6,000 square feet, with multi-zone HVAC systems, pools, and extensive outdoor living spaces. The average Southlake household uses 1,500–2,000+ kWh per month, far above the Texas state average of 1,200 kWh.
Below are the best Southlake plans at four common usage levels, updated daily.
500 kWh/month
Companion Pro + Perks 3 - 9.90¢
$52.00/mo

The U.S. Energy Information Administration (EIA) reports Texas homes average 1,140 kWh/month due to summer air conditioning demand.

Plans with higher renewable percentages use Renewable Energy Certificates (RECs) to offset your consumption. Same Oncor Electric Delivery delivery, same reliability. Pricing is often comparable to conventional plans, and no home modifications are required.
How much are electricity delivery charges in Southlake?
In Southlake, Oncor Electric Delivery delivery charges are regulated by the Public Utility Commission of Texas (PUCT) and apply uniformly to all customers. These fees cover the physical grid — poles, wires, transformers, meters, and outage crews. Plan rates advertised on comparison sites generally include delivery charges already. The Electricity Facts Label (EFL) for every plan shows the exact split between supply costs and Oncor Electric Delivery’s delivery fees.
Should I choose a fixed or variable rate plan in Southlake?
A fixed-rate plan in Southlake locks your per-kWh supply rate for the contract term, shielding you from ERCOT wholesale price swings. Variable plans may start lower but can increase monthly without notice. With Southlake fixed rates starting at 6.4¢/kWh, locking in before summer — when Texas wholesale prices historically spike — gives most households more predictable bills and lower overall costs.
Are renewable energy plans available in Southlake?
Yes, and they’re often price-competitive with conventional plans in Southlake’s Oncor territory. Green Mountain Energy, Gexa Energy, Chariot Energy, and several other providers offer 100% renewable electricity plans backed by Texas wind and solar renewable energy credits (RECs).
Texas’s massive wind and solar generation capacity means green plans are no longer the premium they once were. In some months, the cheapest plan available in Southlake is a 100% renewable option.
For Southlake homeowners with rooftop solar panels, providers like Chariot Energy, TXU, and Rhythm offer solar buyback programs that credit you for excess generation exported to the grid. Given Southlake’s high electricity consumption, even a modest rooftop solar array can generate meaningful credits during peak sunlight hours.
How should I compare plans given Southlake’s high electricity usage?
This is the most important question for Southlake homeowners, and the answer is simple: do not compare plans at 1,000 kWh alone. Most Southlake homes use 1,500–2,000+ kWh per month, and many hit 2,500–3,500 kWh during peak summer.
Some electricity plans use bill credits that make them appear cheap at exactly 1,000 kWh but become the most expensive option at higher usage levels. Always check the Electricity Facts Label (EFL), which Texas law requires to show rates at 500, 1,000, and 2,000 kWh.
Compare plans at 2,000 kWh as your primary benchmark. Look for plans with a flat per-kWh rate (no bill credits) for the most predictable pricing at Southlake-level usage. A plan that’s 0.5¢/kWh cheaper at 2,000 kWh saves you $10/month, or $120–$360 over a typical contract term. That small rate difference is magnified by Southlake’s high consumption.
How do Southlake business electricity rates work?
Southlake 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, commercial pricing includes energy charges plus demand charges based on your peak usage (measured in kW).
Businesses along Southlake’s SH-114 corridor, in Southlake Town Square, and throughout the city’s commercial districts can typically save 15–30% by shopping providers versus staying on a default or expired rate.
