The competition in Texas' electric industry, which allows customers to choose their electricity provider, has resulted in Texas electric rates falling over the past few years -- during the same time that electric rates are on the rise nationally.

The Association of Electric Companies of Texas (AECT) recently noted that from August 2006 and August 2011 (the latest data available), the national average electric rate for residential customers rose by 11%, according to data from the Energy Information Administration (EIA).

However, during this same time period, the Texas statewide average residential electric price fell by 14%, according to the EIA data.

And rates fell even more in parts of Texas where customers have a choice in their electricity provider.  AECT noted that when comparing competitive offers from electric suppliers as archived by the state's Public Utility Commission, the average residential offer in Texas' competitive electric market dropped by 32% from August 2006 to August 2011.

The data once again shows that customers save money on their electric bills when they can choose their energy supplier can get competing electric companies to offer them lower rates.

Although opponents of such electric choice continue to spread myths about electric competition, AECT's data confirms what is evident in other data sets and comparisons as well.

As recently noted by SaveOnEnergy.com, Texas electric rates are lower today, thanks to competition, than they were 10 years ago before competition -- and that's even without adjusting for inflation.

Furthermore, despite much noise to the contrary, SaveOnEnergy.com noted that electric rates in Dallas and Houston, where customers can shop for their electricity provider, are lower than in most of the "regulated" (or monopoly) areas of the state, including utilities like El Paso Electric and Entergy Texas, munis like Austin Energy, and cooperatives like CoServ.
