Corsicana Electricity Rates

Corsicana is in Texas’s deregulated electricity market, meaning you choose your retail electric provider (REP) rather than being locked into a single utility. Oncor Electric Delivery owns the poles, wires, and meters and delivers power to every home in Corsicana regardless of which REP you pick. Your REP handles your bill, customer service, and your per-kWh rate. The Public Utility Commission of Texas (PUCT) licenses and oversees all providers, so every REP listed on this page is a regulated, legitimate option.

The cheapest Corsicana electricity rate is 7.5¢/kWh at 1,000 kWh usage, offered by Chariot Energy (GridPlus 12 - 7.50¢). The average rate across all 200 available plans is 13.47¢/kWh. Rates are updated multiple times daily.

At the current average rate of 13.47¢/kWh, a Corsicana home using 1,000 kWh/month would pay about $135/month. Most Corsicana homes use 1,000–1,200 kWh/month. Summer bills run significantly higher, especially in older homes with less insulation — expect $150–$300+ during July and August when Central Texas temperatures regularly exceed 100°F.

Oncor Electric Delivery is the transmission and distribution utility (TDU) for Corsicana and all of Navarro County. Oncor owns the power lines, transformers, and meters. They handle outage restoration, new service connections, and meter reads. Your retail electric provider (REP) is a separate company that sells you the electricity and sends your bill. You can reach Oncor at 888-313-4747 or online at oncor.com.

No. Corsicana is the Navarro County seat, located about 55 miles south of Dallas on I-45. It’s an independent city with its own economy, history, and identity — not a DFW suburb or bedroom community. Corsicana was a boomtown before Dallas was a major city, thanks to the Corsicana Oil Field discovered in 1894 (the first major oil strike in Texas). While some residents commute north to the Dallas area, Corsicana has its own downtown courthouse square, its own economic base in oil services, agriculture, and manufacturing, and a population of about 25,000. For electricity purposes, both Corsicana and Dallas are served by Oncor, so you have access to the same providers and similar rates.

Corsicana has a large stock of historic homes dating from the 1890s oil boom through the 1940s. These homes often feature original single-pane windows, minimal wall insulation, and older HVAC systems, which can push summer electricity usage to 1,500–2,000+ kWh/month. If you live in one of Corsicana’s historic homes, compare plans at the 1,500 and 2,000 kWh levels — not just 1,000 kWh. Consider weatherization upgrades that preserve the home’s character (storm windows, attic insulation, duct sealing) while meaningfully reducing energy costs. A well-insulated historic home can cut summer bills by 20–30%.

Navarro College students renting off-campus apartments or houses in Corsicana can choose their own electricity provider just like any other resident. Look for short-term plans (3–6 months) that align with the academic semester, or month-to-month variable plans with no early termination fee if you’re unsure how long you’ll stay. Prepaid (pay-as-you-go) plans are another solid student option — no credit check, no deposit, and no contract commitment. If you’re sharing a house, make sure the electricity account is in one person’s name to avoid complications.

Shop in spring (February–April) or fall (October–November) for the lowest rates. Wholesale electricity costs drop when air-conditioning load is light, and REPs pass those savings into lower fixed-rate offers. Avoid signing a new contract in June through August, when ERCOT grid demand peaks and retail rates can be 20–30% higher than spring. If your contract expires mid-summer, consider a short-term month-to-month plan until fall rates improve.

Contact Oncor Electric Delivery at 888-313-4747 for all power outages in Corsicana. Oncor owns the infrastructure and handles all outage restoration regardless of which retail provider you use. You can also report outages and check restoration status online at oncor.com. Do not call your retail electric provider for outages — they cannot dispatch crews.

Texas law (PUCT Substantive Rule §25.475) requires your REP 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 higher — often 15–20+ ¢/kWh. Set a calendar reminder about six weeks before your contract end date, shop for new plans on this page, 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 contract.

Central Texas summers regularly push past 100°F, and Corsicana is right in the thick of it. Air conditioning accounts for 50–70% of summer electricity costs. A home that uses 800–900 kWh in March can easily hit 1,500–2,000 kWh in July and August. Corsicana’s older housing stock is especially vulnerable — homes from the oil boom era with original windows and thin insulation work AC units harder than newer construction on the city’s edges. To keep costs down: set your thermostat to 78°F, use ceiling fans, seal drafty windows, and get your AC serviced before summer. Also compare plans at your actual summer usage level, not just the 1,000 kWh benchmark.

Corsicana 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 peak usage. Whether you run a downtown Beaton Street shop, a service company near the oil fields, or even the world-famous Collin Street Bakery, you can shop multiple providers for competitive commercial rates in Oncor territory.
