Why Georgetown IS 100 Percent Renewable

Reports by a local newspaper and an anti-renewable energy advocacy organization attempted to question Georgetown’s status as an electric utility using 100 percent renewable energy.

Georgetown is credited with the energy it pays to put into the statewide electric grid. Since April 2017, the City has been credited with putting more renewable energy into the grid than customers consumed. According to the statewide renewable energy accounting system, overseen by the Public Utilities Commission, Georgetown’s customers have been using and paying for all-renewable energy since April 2017.

The Electric Reliability Council of Texas (ERCOT) manages the statewide electric grid. ERCOT also tracks renewable energy production for the City. The City is able to determine its energy consumption based on data from customer meters. When determining what percent of an electric utility’s energy portfolio is renewable, the energy produced is compared to the energy consumed. For example, in 2018:

• Georgetown contracted for 1,067 megawatt hours of energy.

• Of that, 822 megawatt hours were from renewable sources.

• Georgetown customers consumed 678 megawatt hours.

In 2018, the total energy consumption by Georgetown customers was less than the total energy produced by renewable sources. That means Georgetown qualifies as being 100 percent renewable in Texas.

The City does not physically use renewable energy every second of every day, but the City does produce more renewable energy than its customers consume. As long as this trend continues, Georgetown will be considered 100 percent renewable. All utilities in Texas base their renewable percentages using this method.

The City never claimed that the electrons produced by its energy contracts are the same electrons consumed in Georgetown. In fact, a commentary published by the Austin American-Statesman Aug. 11 states, “[t]he city did not set out to influence other energy providers or shakeup the state grid. We know that Texas is reliant on traditional sources of energy. We know it is impossible to track an electron produced in West Texas all the way to Georgetown. However, we also know that the state attributes all of wind farm and solar farm production with Georgetown.”  

Contrary to some reports, the City does not have a policy to be 100 percent renewable in its energy supply. In 2014 and 2015, the City selected wind and solar energy providers because of long-term cost stability and reduced regulatory risk. The City’s goal is to have 30 percent of its energy from renewables by 2030.

Texas’ Energy Grid 

ERCOT manages the flow of electric power for 90 percent of the state’s electric load. This interconnected system means all sources of energy enter into and are consumed off the statewide grid.

Georgetown is reliant upon energy from the grid to ensure customers receive reliable energy. As a member of ERCOT, the City of Georgetown is obligated to purchase, place, and ultimately provide energy to customers using the ERCOT-managed grid.

The City is under contract to purchase energy from four providers. The two largest are Spinning Spur 3, a wind farm near Amarillo, and Buckthorn, a solar farm near Fort Stockton.

The third source of energy is a smaller wind farm operated by American Electric Power (AEP) which primarily covers Southwestern University’s energy needs.

The final energy contract is with Mercuria for natural gas-based energy. This contract was initiated and is a short-term power supply, set to expire in 2022.

The energy production for each of these contracts, as well as Georgetown’s electric consumption, is included in the graph.

As the graphic illustrates, since 2017 Georgetown’s wholesale energy contracts produced more renewable energy than customers consumed.
