Why do our rates look different from other sites?
Most comparison sites show the rate from your plan's Electricity Facts Label at exactly 1,000 kWh. We estimate your total monthly cost — including Texas-New Mexico Power delivery charges — at your selected usage level. This gives you a more complete picture of what a plan is likely to cost, not just the energy rate.

What Affects My Electric Bill in Newcastle?
In the deregulated market of Newcastle, residents have the power to choose their own Retail Electric Provider (REP). However, regardless of which provider you choose, your electricity is still delivered by the same local Transmission and Distribution Utility (TDU).
In this area, the TDU is Texas-New Mexico Power. They are responsible for maintaining the power lines, reading your meter, and restoring power during outages. Their "pass-through" charges are regulated and will be the same across every plan you see on Watt Owl.
Understanding how your usage affects cost is important because not all plans price electricity the same way. At Newcastle's local average of 1,065 kWh/month, delivery charges from Texas-New Mexico Power add approximately $84.92/month to your bill before your energy rate. During peak months like July when usage can reach 1,532 kWh, those delivery charges increase proportionally. That's why comparing plans at your expected usage level — rather than at standard breakpoints — can reveal meaningful differences between plans that look similar on paper.
Of the 108 plans currently available in Newcastle, 98 are fixed-rate, 10 are variable-rate, and 8 include bill credits. Contract lengths range from 1 to 60 months.
For most homes in Newcastle, a fixed-rate plan offers the most predictable monthly costs — especially during summer when usage can jump to 1,532 kWh. Of the 98 fixed-rate plans available here, contract lengths range from 1 to 60 months. The 8 bill credit plans in this area can offer lower rates at specific usage thresholds, but may cost more if your monthly usage varies seasonally. Variable-rate plans (10 currently available) offer flexibility but carry pricing risk during high-demand months.
As of March 2026, some of the most competitive plans in Newcastle include the True Value 12 from TRUE POWER at 14.79¢/kWh, the Stars and Stripes Green Flex from REVOLUTION ENERGY LLC at 11.46¢/kWh, and the GridPlus 12 from CHARIOT ENERGY at 11.56¢/kWh. Rates are estimated at 1,065 kWh/month, the local average for this area.

Currently, one of the most competitive plans in Newcastle is the True Value 12 from TRUE POWER at 14.79¢/kWh. At 1,065 kWh/month, this plan costs approximately $157.56/month.

Yes! Newcastle is in the deregulated Texas electricity market, which means you can choose from dozens of Retail Electric Providers (REPs). While Texas-New Mexico Power handles delivery, you pick the company that sets your energy rate. Switching is free and takes about 15 minutes online — your power stays on the entire time.
Homes in Newcastle use an average of 1,065 kWh per month, or about 12,774 kWh per year. Usage peaks in July at around 1,532 kWh due to air conditioning demand, and drops to its lowest in January at around 850 kWh.
The best time to switch is during shoulder months (March–April and October–November) when demand is lower and providers often offer competitive rates. However, you can switch anytime with no interruption to your service. Currently, rates in Newcastle start as low as 11.46¢/kWh for fixed-rate plans.
When your contract ends, your REP is required to send an expiration notice at least 14 days before your contract expires. If you don't select a new plan before expiration, you'll typically be moved to a month-to-month variable-rate plan, which is often more expensive than a fixed-rate contract. We recommend shopping for a new plan at least two weeks before your contract ends to ensure a smooth transition.
Switching providers is free and straightforward. Choose a new plan, complete the enrollment with the new REP, and they handle notifying your current provider. Your power stays on throughout the process — Texas-New Mexico Power continues delivering electricity regardless of which REP you choose. Most switches take effect within one to three business days after your enrollment is processed.
