ERCOT Summer 2024 Outlook
Dive into our outlook for ERCOT’s summer 2024. We’ll cover the anticipated weather conditions, transmission outages and congestion risks for ERCOT month-by-month to help you navigate the complexities of the ERCOT market this summer.
June 2024
Weather and Load Forecast
- June is expected to start on the cooler side, especially east of the Rockies. This is influenced by the transition from El Niño to La Niña conditions, leading to lower load due to cooler temperatures.
- However, lower wind might introduce some bullish tendencies, but June is still expected to be bearish.
Transmission Outages and Congestion Risks
- West Hub Premium: Long-term transmission outages in the West, impacting West Hub.
- Congestion Constraints: Yellow Jacket to Hex, Bell County and La Palma to Hand will see congestion, impacting prices.
Prices:
- Due to higher precipitation and cooler conditions, prices are expected to be lower than market average.
- There is a risk of volatility in evening non-solar hours.
July 2024
Weather and Load Forecast
- July is anticipated to be hot, with temperatures averaging above 88°.
- Southerly winds pushing heat into the plains could lead to increased wind production, offsetting some of the heat-driven demand increases.
Transmission Outages and Congestion Risks
- Increased Demand: Houston, South and Central Texas will see higher demand, impacting hub basis.
- Congestion Constraints: Deer Creek, Bell County, Gabriel Transformer and La Palma to Hand are key constraints to monitor.
Prices:
- Above average load and high wind production may lead to lower net load.
- Expected heat rate is lower than market.
August 2024
Weather and Load Forecast
- August is expected to be very hot, with temperatures potentially exceeding 105° in key areas like Dallas and Houston.
- Reduced solar production due to shorter days and significant heat will drive up demand and prices.
Transmission Outages and Congestion Risks
- High Solar Capacity: Continued solar additions will increase volatility, particularly in the late afternoon and early evening hours.
- Congestion Constraints: Yellow Jacket, Deer Creek, Bell County and La Palma to Hand will continue to pose congestion risks.
Prices:
- Expected August heat rate is very close to market.
- Expect Peak Net Load HE18-20 to be the riskiest hours in August due to higher contribution from battery discharge.
