What is renewable energy?

Renewable energy is electricity that is produced from sources that replenish themselves naturally. This includes wind, solar, and hydro-electric facilities.

What are Texas’ renewable energy assets?

Our state has abundant solar, water, wind, and natural gas resources, and our members are developing, manufacturing, and installing cutting-edge, high-tech renewable energy systems.

Where does the electricity go?

According to ERCOT, The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 25 million Texas customers — representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 650+ generation units.

ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities.

What is the significance of battery storage for renewable energy?

According to Scientific-American, “The way the world gets its electricity is undergoing a rapid transition, driven by both the increased urgency of decarbonizing energy systems and the plummeting costs of wind and solar technology. In the past decade electricity generated by renewables in the U.S. has doubled, primarily from wind and solar installations, according to the Energy Information Administration. In January 2019 the EIA forecast that wind, solar and other non-hydroelectric renewables would be the fastest-growing slice of the electricity portfolio for the next two years.

“But the intermittent nature of those sources means that electric utilities need a way to keep energy in their back pocket for when the sun is not shining and the winds are calm. That need is increasing interest in energy-storage technology—in particular, lithium-ion batteries, which are finally poised to be more than just a bit player in the grid.”
