The past few years have seen unprecedented changes to the makeup of the U.S. electric power system. The generation mix is changing drastically, driven by falling installation costs for renewables and storage, regulations making fossil fired plants more expensive to operate, and the general drive to decarbonize our electric grid. This has led to renewables and storage expanding rapidly and replacing older fossil fired plants. This trend is expected to only accelerate in the coming years.
Power Market Trends
Over the past five years, intermittent resources like wind and solar have substantially increased their share of electric power generation. This fundamental shift in how our power is generated, away from large dispatchable plants to smaller intermittent and less predictable power sources located far away from load centers, has had significant impacts on wholesale power market dynamics. This increase in intermittent resources has been positive from an environmental perspective, but has had some impacts on market dynamics including increased price volatility, curtailment and congestion.
The shifting magnitude and pervasiveness of congestion due to unpredictable amounts of electricity from renewables, leading to negative congestion pricing.
How energy prices are soaring due to base and mid-merit generators being forced out of the market, increasing price volatility across most U.S. markets.
The growing market conditions of widespread curtailment using data from record-setting wind generation in the Southwest Power Pool.
