New Braunfels Utilities officials projected an increase in the September electricity rate compared to August due to higher costs and volatility in the Electric Reliability Council of Texas market.

The average customer who uses 1,200 kilowatt-hours of electricity in September will see an approximate 8.4% increase, or $12 increase, to their electricity bill, according to NBU.

Diving in deeper

Due to extreme record-setting heat conditions experienced in Texas since June, ERCOT has reported increased electricity use and all-time-high demand.

According to NBU, the extreme heat exacerbated with the ERCOT market redesign and more conservative grid operations results in more expensive power. Texas officials made the decision to prioritize electric reliability over affordability, and that is what is driving up the cost of power.

In September, NBU shifted to monthly power cost forecasting rather than quarterly forecasting due to volatility in the ERCOT market. Updates can be found at
