And just like with any plan, it’s worth it to do the math to see how different scenarios will affect your bill. Take, for example, a home in Sweetwater that uses about 1,000 kWh of energy per month, and is interested in the Texas Essentials 12 plan. Zero percent renewable energy is the cheapest option — but by committing to a $5 monthly charge for its 100 percent “JustGreen” option, it’s actually cheaper than the 60 percent hybrid renewable option.
Residents and business owners have been able to shop Texas electricity supply rates for more than a decade. When Texans gained the ability to choose their desired energy company in 2002, the electric industry divided into two parts: supply and delivery. Retail energy companies in Texas compete for business, offering a variety of term agreements and supply rates for consumers to choose from.
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.
