The increase in retail rates come as companies prepare for surging prices in the wholesale electricity markets where they buy their power. Forecasts of higher than normal temperatures and record power demand are coinciding with the shutdown of at least three coal-fired plants, leading to concerns that temporary shortages on the hottest summer days could send wholesale prices, which typically average less than $50 per megawatt hour, spiking to $3,000 per megawatt hour or higher. (A megawatt hour is 1,000 kilowatt hours.)
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.
Energy sellers must provide collateral to ERCOT to cover expected future costs of buying wholesale electricity and if the companies don’t have enough capital, they get shut down. Breeze Energy, a Dallas-based electricity retailer that sold wind-energy plans to 9,800 customers including many in the Houston area, got caught in that financial squeeze when it defaulted on its collateral obligations.
