However, the energy storage sector will continue its strong showing from 2016, with commissioned capacity set to exceed 1GW for the first time, Liebreich and McCrone say. “We predict a doubling of new capacity from this year’s 700MW to 1.5GW, almost all of it lithium-ion batteries. We are going to see a further reduction in battery prices of at least 15% this year, after a 70% reduction in the past five years.”
Residential real-time pricing customers pay electric supply prices that vary by the hour. To make a meaningful comparison between variable RRTP rates and RES offers, customers should compare their past electric supply cost savings from the total Electric Supply section of the bill, provided by their RRTP provider, with an electric supply cost savings estimate provided by RESs. Alternatively, customers can compute their average real-time hourly price in cents per kWh (each month the average real-time price is equal to the total of the Electric Supply section of the bill divided by the monthly kWh) to compare with RES offers posted in cents per kWh. Customer should bear in mind, however, that because RRTP rates vary over time, past savings do not predict future savings, but only serve as a guide to compare past performance.
Once you sign up for your new energy plan, your local utility will be notified of the change and begin your service from the alternative supplier at the beginning of your next billing cycle. Upon starting your energy supply service, your utility company will include this charge on your energy bill and continue to charge for the delivery service portion of your bill. Why? Because although your supplier may offer you a competitive rate for electricity supply, your utility is still in charge of the infrastructure that delivers energy to your home – such as power lines and energy meters.
On the one hand, long-term, fixed-rate (contract) plans offer stability in pricing. If energy supply costs suddenly go up in your area, you won’t be left paying more than what you bargained for.  You’ll have peace-of-mind.  If you want to switch out of your contract before it ends with a lower cost plan, you’ll likely face a cancellation fee (early termination fee).
Some good news: According to J.D. Power’s 2016 survey on retail electric providers (its most current survey of the space), Texas has the highest overall satisfaction with retail electric providers out of any state. And because rates, plans, and offers can be so similar from provider to provider, customer satisfaction scores are a great way to break a tie. Think of it like choosing who to hire when you have two candidates with similar resumes — you’re going to pick the person with the glowing references.

Price, of course. Prices are expressed in cents/kilowatt hour. Plan types include fixed rates and variable rates. Fixed rates offer consistency throughout the plan term, which can run from six to 36 months. Variable rates can change monthly - they're great when prices go down, but not-so-great when they don't. Finally, if you care about your carbon footprint, you may choose a plan sourced by solar or wind energy.

Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
That means that customers in Houston paid an average of $5,500 more for electricity over a 14-year time span beginning in 2002, according to the group that buys electricity on behalf of municipal governments in Texas. The calculation, which uses data from the U.S. Energy Information Administration, assumes monthly electricity use of 1,300 kilowatt hours.
