TDU Delivery Charge: TDU stands for transmission and delivery utility — in other words, the utility company in your area that is actually piping the energy from the power generation companies into your home. (Remember, REPs in Texas are just the middleman.) The TDU delivery charge is set by the utility and is consistent from plan to plan and provider to provider within its service areas. For example, AEP , the TDU for Corpus Christi, charges the same delivery fee for all TXU, Direct Energy, and Reliant plans. You don't typically get a choice in utility company, and therefore, these fees are pretty much unavoidable, non-negotiable, and won't factor into choosing an electricity plan or provider.
For example, shoppers for Texas electricity plans in the 77494 ZIP code in Katy, TX, could find 12-month plans for 6.8 cents/kWh in February; by June, electricity rates had increased 27 percent to 9.3 cents/kWh. As of early September, 12-month plans were up again, to 9.9 cents/kWh – a 6.5 percent hike from June and a 46 percent increase just since February.
As a renter, you’re likely concerned about getting your electricity contract’s start and end dates to match your lease term as close as possible. In most cases, your electricity provider will offer flexible start dates and some even offer same-day connections. If you can’t line up your electricity contract exactly with your lease term, it’s okay. It’s better to choose an electricity plan with a slightly longer contract term than your apartment lease if necessary. If you move and provide proof of a change in address, your electricity provider cannot charge you an early termination fee.
Fixed-Rate Plans: These plans are steady and predictable; the price per kWh you sign up for will remain that same for the entirety of your contract. (The only changes in your bill will be from forces outside of your REP's control, like changes in TDU fees, or changes in federal, state, or local laws.) Often fixed-rate plans will have a slightly higher price per kWh than others, but you're paying for the predictability. They're great if you live by your budget – and even greater if you happen to sign up when rates are low. The fixed-rate plans of our five Texas providers typically started at 12 months, with some extending up to three years, but we spotted a couple from Reliant that offered fixed rates for six month contracts as well.

And just like with any plan, it’s worth it to do the math to see how different scenarios will affect your bill. Take, for example, a home in Sweetwater that uses about 1,000 kWh of energy per month, and is interested in the Texas Essentials 12 plan. Zero percent renewable energy is the cheapest option — but by committing to a $5 monthly charge for its 100 percent “JustGreen” option, it’s actually cheaper than the 60 percent hybrid renewable option.
Compared to the rest of the nation, data from the U.S. Energy Information Administration which publishes annual state electric prices  shows that Texas' electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but, from 2010 to 2015 have moved significantly below the national average price per kWh, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 nationally, or 17 percent lower in Texas. Between 2002-2014 the total cost to Texas consumers is estimated to be $24B, an average of $5,100 per household, more than comparable markets under state regulation. 
1. Legacy providers no longer rule. Get over the idea that original providers are the only companies that can offer solid, uninterrupted service. And don’t believe the fallacy that customers of legacy providers get serviced first when power goes out. Oncor Electric Delivery is responsible for maintaining the transmission system. Everybody uses Oncor to handle repairs in our region.
