Which ones the best? Like all things energy, it depends. Do you prefer predictability, or do you like the idea of potentially saving some cash by monitoring the market? Our (albeit conservative) recommendation: Fixed rate is probably best. Energy prices are on the rise — the U.S. Energy Information Administration predicts a 3 percent increase in residential electricity prices in 2018.
With over 2.3 million residents, Houston is the largest city in Texas and the fourth most populated in the United States. Encompassing over six hundred square miles, Houston stands as the fifth most popular metropolitan area in the country and gets its name from the commander who won Texas’ independence from Mexico in 1836. The city lies in the southeastern portion of the state within a deregulated Electricity market and as such, allows residents to select an energy provider from the various service companies that serve the state.
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.
