Technology that now allows smaller quantities of power to be generated closer to the end-users at prices not too much higher than grid-based power are undermining those economies of scale. More efficient turbines, for example, allow large power users like cement plants and petrochemical factories to come off the grid. Today the limiting factor for large companies to come off the grid often isn’t the efficiency of the power generation technology, but the lack of easy availability of fuel, such as gas or coal to power these turbines Even this problem is being solved by innovations like mini-liquefied natural gas projects.
The local electric company is the utility – that’s the company who owns the infrastructure, including the poles and power lines that deliver electricity to your home. They are who you call if your power goes out or there's an emergency. But in almost every city in Texas, you must choose another company to supply that energy, called a Retail Electric Provider (REP). These REPs, like Spark Energy, allow you to choose electricity plans that offer competitive prices and plans to meet your needs.
