Due to the increased usage of natural gas immediately after deregulation, new-era energy tools such as wind power and smart-grid technology were greatly aided. Texas' first "renewable portfolio standard" — or requirement that the state's utilities get a certain amount of their power from renewable energy like wind — was signed into law in 1999, as part of the same legislation that deregulated the electric market.
Twenty bucks compared to a $2,000 bill? Not much to write home about, but hey — it’s free money. And, true, you’ll still get some free money when you use less energy, but rewards only really seem reward-y if you're shelling out big bucks. That same Direct Energy plan only yields about $6 in Plenti points per year if you use 500 kWh of electricity each month.
In this free market competing electricity retailers buy electricity wholesale from private power generators to sell at retail to around 85% of Texas residents. The partnership between generators and retailers is governed by the Electric Reliability Council of Texas, or ERCOT, which attempts to balance the power grid’s electricity supply and demand by purchasing small amounts of electricity at 15-minute intervals throughout the day.
