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.
In Houston, 0% of people have switched to a plan that has some renewable energy component to it. Another 0% have switched to a plan that is partially renewable, while 0% have switched to a plan that powers homes completely by renewable electricity. This of course means that 100% of people have remained on a plan powered by traditional sources of electricity such as coal or nuclear power.
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.
Shopping for a plan based on renewable sources is no different than shopping for any other kind of plan — you calculate your costs the same way, look for the same fees, and weigh in customer satisfaction and other perks. The one thing that’s different is also looking at what percentage of your energy comes from renewable content in the EFL. That number can swing from as low as 0 percent all the way up to 100 percent, with the majority of plans that partially offset energy with renewable content hovering around 15 percent.
For example, if you use a small amount of energy each month, you expect to be rewarded — right? Unfortunately, nearly all electricity plans from Texas REPs are advertised as costing more per kWh the less electricity you use. It’s a little like buying in bulk: Providers often discount your bill when you cross certain kWh thresholds. For instance, one 12-month plan from StarTex Power quotes 8.1 cents per kWh for 1,000 kWh a month and 8.8 cents for 2,000 kWh per month, but 12.1 cents for 500 kWh per month. Why the difference? Customers get $35 back each month if they pass 1,000 kWh of use, and another $15 back per month if they cross 2,000 kWh. In this case, using half as much electricity as your neighbor on the same plan wouldn’t get you half the bill.
As they’re advertised, the Digital Discount plan appears to save you $4 — but only if you use 32 percent of your energy on the weekends, which is the stat Reliant used to create the average price it advertises. Say you often travel for business during the week, and are only home cranking the air conditioner on weekends. If your energy use skews to 55 percent weekend use (for Reliant, that means 8 pm on Friday through 12 am Monday), suddenly Truly Free Weekends becomes a much better deal.
When you’re choosing a new energy deal, think about whether to go for dual fuel (where you get both your gas and electricity from the same company) or separate tariffs (where you get gas from one company, and electricity from another). It’s worth checking both options, as the combined price of separate tariffs can sometimes be less than a dual fuel offer.
