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.
You betcha! Most Texas electricity suppliers offer plans that include a percentage of energy sourced from renewable resources, such as hydro power, wind power and solar power. Some are totally sourced that way. These plans are a great way for Texas energy customers to help the environment without breaking the bank. In addition to green energy plans, many Texas suppliers give customers the option to purchase renewable energy certificates, or RECs, that further offset customers’ carbon emissions. The purchase of RECs also helps fund research and usage of renewable energy sources, so that Texas can stay at the forefront of eco-friendly power technology.
You can sort, filter, and shop by pricing at YOUR specific usage level, which lets you shop and compare electricity plans based on the rates you’ll actually experience on your bill, inclusive of hidden fees and taxes. This ensures you’re not misled by the cheaper rates often advertised by electric providers…those “teaser rates” associated with higher usage levels that many households never enjoy because their usage level never reaches that pricing tier.
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.
