Drought, Temperatures and Electricity in Summer 2022

The Federal Energy Regulatory Commission, FERC and the North American Energy Reliability Corporation, NERC, have released their annual their summer power reliability assessment. These two reports provide an assessment and evaluation of the electrical power generation and transmission system adequacy to meet projected summer peak demands. The news is not good. 

NERC forecasts that all regions will have sufficient power to meet demand during normal conditions, but all regions may face energy shortfalls (blackouts) during heat waves or low wind conditions. This is especially in the West and upper Midwest where  a nuclear plant was shut down on May 20th without adequately replacing the generation. 

The drought in the west reduces hydroelectric power generation and raises the risk of blackouts there.  The bottom line is the United States can no longer guarantee 24/7 electricity through high demand periods. In addition, the wholesale electric markets expect to see higher prices this summer because of hotter temperatures, slightly increased demand, and higher natural gas prices. This could play out as a failure of policies and planning in the highly regulated electric market.



With different emphasis both reports identify potential reliability issues especially in the western United States. Temperatures have a significant impact on demand for electricity, and higher than average temperatures are expected for the coming summer. The U.S. National Oceanic and Atmospheric Administration (NOAA) forecasts for June 2022 through September 2022 suggest a 50% to 80% likelihood of higher-than-average temperatures.

Drought conditions also create heightened reliability risk for the summer. Drought exists or threatens wide areas of North America especially the west currently in the grips of an unpresented drought. Dry hydrological conditions threaten the availability of hydroelectricity for transfers throughout the Western Interconnection, and will reduce the availability of hydroelectric power in total. Hydroelectric power is the most reliable of the renewable options in the northwest and California plans for the availability to purchase that power when their own generation is inadequate. However, they do not purchase the rights to that power in advance of need.

Natural gas prices for summer 2022 are expected to rise across the U.S. The futures contract price at the Henry Hub is averaging $7.06 per million British thermal units (MMBtu) for June 2022 through September 2022, up 88% from last summer’s average price of $3.75/MMBtu. Furthermore, demand for natural gas is expected to increase 4.8% over summer 2021 levels to 89.8 billion cubic feet per day due to increases in Industrial, Residential/Commercial, power generation, and net export of natural gas.

This is summer demand when natural gas is not used for heating.


The western U.S. continues to face extreme drought conditions, increasing the likelihood of significant wildfires and reducing the amount of hydropower available. Another risk to the reliability of electrical power is the potential for wildfire. The risk of wildfires may require transmission operators to proactively shut down power in areas of active fires, or during extreme heat and wind conditions to reduce the likelihood of electric equipment sparking fires.

The low reservoir and snowpack levels indicate that the West will see less hydropower as less water is available to move through generators and as reservoir water levels fall below those necessary to operate generation equipment safely. As of May 11, 2022, after below-normal accumulations all winter, late spring storms have brought snowpack levels in the Pacific Northwest above normal, while California’s snowpack level stands at just 22% of normal for this time of year. Everything will have to go right for the electrical grid to function normally all summer. Let's hope.
