Here are my 2 cents about electric companies when shopping around for the best rates. Currently, the average cents/kWh in Houston is 10 cents, after speaking to a very helpful, very informative Green Mountain Energy representative. Although their rates are a little higher than my current rates, they have FANTASTIC customer service (which is almost worth it). The GME rep even recommended that I stick with what I am using now since it's cheaper.
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.
