Green Mountain Energy

Green Mountain Energy launched in 1997—before Texas even deregulated its electricity market. They've been selling 100% renewable energy longer than any other American retailer. When Texas opened to competition in 2002, Green Mountain was ready with established wind farm contracts. NRG Energy acquired them in 2010, providing Fortune 500 financial backing. But Green Mountain has maintained its Austin headquarters and environmental mission. They're not just buying renewable energy credits—they have long-term contracts with actual wind and solar farms. Their rates run slightly higher than Gexa (another 100% renewable option). The premium reflects their 28-year track record and the brand's genuine environmental commitment. For customers who want the "original" green energy provider, Green Mountain delivers.

Green Mountain offers simple, straightforward plans: Fixed Rate (Pollution Free 12/24): Lock in your rate for 1-2 years. 100% renewable included. Month-to-Month (Pollution Free Variable): No contract, cancel anytime. Higher rate but maximum flexibility. Great if you're renting or might move. All plans are 100% renewable. No need to choose a "green" version—it's all green.

Green Mountain's rates typically run 11¢ to 15¢ per kWh—about 10-15% higher than Gexa but competitive with TXU and Reliant. Why pay more than Gexa? You're paying for: - 28-year track record (vs Gexa's 23) - Austin-based company culture - Additional carbon offset programs - The "original" green energy brand Is it worth the premium? That's subjective. If lowest rate matters most, Gexa wins. If you value Green Mountain's longer history and mission-driven culture, the premium may be worth it.
