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.

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.
It is not a well-known fact that consumers can take advantage of energy deregulation and choose an alternative energy supplier, known as an Energy Service Company (ESCO). In addition to offering lower electricity and gas rates, an ESCO can provide other energy options, not otherwise available by your local traditional utility company, such as renewable green energy (solar, wind or hydropower) and fixed-rate plans. Energy deregulation allows residents and businesses to shop around for energy, compare electricity and gas rates, find the cheapest providers and easily switch electricity and gas suppliers online. Compare ESCOs and their rates, choose the cheapest electricity or gas provider, and you can reduce your energy expense, such as Con Edison electric or gas bill, if you live in New York City, or United Illuminating or Eversource bill if you live in Connecticut or Public Service Electric and Gas, Jersey Central Power and Light, Atlantic City Electric, Rockland Electric Company bill if you live in New Jersey. PowerSetter specializes in educating New York, New Jersey and Connecticut residents about comparing electricity and gas providers, and making switching energy suppliers an easy and painless process. In addition to offering tools to compare energy rates, PowerSetter only selects plans with no hidden monthly and/or enrollment fees and works with the most reliable and trusted alternative electric and gas companies.
Fixed-rate, long-term (contract) plans provide stability in electricity rates. If market energy costs suddenly trend upward where you live, you can rest assured that you won’t have to pay more out of pocket. However, if you want to switch to a different, lower-cost plan before the end of the contract term, you’ll likely have to pay a cancellation or early termination fee.
