ERCOT hit record power demand as temperatures soared into the triple digits for much of the Lonestar state.
On June 27th, ERCOT (Electric Reliability Council of Texas) hit record power demand as temperatures soared into the triple digits for much of the Lonestar state.* The grid operator faced its highest demand level to date of 80,828 MW from 6-7pm. Reuters cites that, “at the peak hour on Tuesday, wind and solar provided about 35% of the power in ERCOT versus 44% from gas, 14% from coal and 6% from nuclear.” With confidence in supply and demand, June 27th, 2023, was a much different story for the grid operator than July 13th, 2022, when demand threatened to meet supply.
Weather dependent renewable energy resources like solar and wind energy played a significant role in keeping the market participants comfortably online and AC units pumping out cool air. Renewable resources, particularly solar, will increasingly play a critical role in the state’s energy infrastructure. “The US Energy Information Administration estimates the Lone Star state will install more utility-scale solar capacity in 2023 than any other state, around 7.7 gigawatts this year alone and the federal energy administration expects the state to bring another 24.8 gigawatts of additional solar capacity online by the end of 2025. Together, that is enough to power over 10 million homes,” cited CNN Business News.
Climavision has developed forecasting solutions tailored specifically towards renewable energy resources, to be used by market participants in scenarios just like this, to understand what is happening where wind turbines sit in the atmosphere, and what value of solar irradiance is expected for the day.
*The record for energy demand on June 27th has since been broken multiple times over the course of July and August.
GRO Forecast Model
Climavision’s proprietary GRO (Global Radio occultation and Observations) forecast model produces variables tailored to anticipated performance from renewable energy sources, particularly solar and wind. Parameters include Cloud Coverage % and 80 Meter Hub Height Winds.
JUNE 13, 2023
On June 13th, two weeks before the new record was set, GRO called for triple digit heat across most of the state of Texas. In addition, GRO forecasted weak winds at 80 meters. The strongest sustained winds were forecasted to only reach 10 knots.
June 17, 2023
The same goes for June 17th, 10 days out from the record being set. While GRO called for slightly stronger winds at up to 15 knots, the forecast remained rather steady with much of Texas experiencing still conditions alongside triple digit heat.
