Media Advisory: Prolonged periods of negative pricing in Q1 set new record

REsurety’s REmap Q1 State of the Renewables Market report presents generation-weighted value, shape value, and capacity factor for major U.S. hubs

BOSTON, MAY 10, 2022 – The U.S. power grid saw record lows in the first quarter of 2022, REsurety’s REmap Q1 2022 State of the Renewables Market Report finds, with prolonged negative pricing in Texas expected to ease this summer.

Unlike the soaring prices of last year during the Texas energy crisis of February 2021, this year the ERCOT power grid saw record lows in Q1. It was another turn in a developing plotline REsurety commented on last quarter. 

One example: In February 2021, ERCOT West Hub (among others) settled at the market price cap of $9,000/MWh for three days; in February 2022 ERCOT West Hub saw a two day period where prices never rose above $0/MWh. Mild demand coupled with sustained periods of high wind and solar generation created the conditions for this negative pricing event, though these conditions weren’t isolated to only those few days. In fact, by the end of the quarter, West Hub more than doubled the number of negative-priced hours than were seen in Q1 the year prior.

REsurety creates the REmap-powered State of the Renewables Market report every quarter to provide readers with data-driven insight into the value and latest emerging trends of renewables in U.S. markets. The team uses its knowledge in power markets, atmospheric science, and renewable offtake to analyze thousands of locations, and summarize a few key findings, using the data that is available via its interactive software tool, REmap.

Key components in the report to be used to analyze trends in a given ISO, sub-regions of an ISO, or hub, are:

  • The generation weighted value, or the realized value of the wind and solar projects 
  • The shape value, or the relationship between the generation value and the simple-average market price
  • The net capacity factor for operating wind and solar projects

“Using the modeled energy in REmap, which tells us how projects could have performed based on underlying wind/solar resource availability, last quarter West Texas solar projects saw anywhere from 20 to 30% of their potential hourly production for a given month happen in negatively priced hours. However, in reality, these projects weren’t operating at their potential capacity in these intervals, and either shut down or significantly ramped down production,” reports Blair Allen, Director, Software Customer Success, REsurety. 

Over the next quarter as the weather starts to transition to summer conditions negative pricing is expected to decline. With an increase and shift in demand, Q2 will likely be a transitional period, with the frequency of negative pricing hours remaining high to start before subsiding more materially by the end of the summer in mid Q3. 

The power of REmap lies in the historical and predictive modeling for renewable energy projects across the United States, as well as the ability to analyze hypothetical installations. Learn more by reading the Q1 report

Editor’s Note: As the first quarter of 2022 concludes, we reflect on historic highs and historic lows. Another record in ERCOT marks the quarter’s passing, just as one did a year ago following the market events of February 2021. However, unlike the soaring prices of last year, this record involves a prolonged period of negative pricing, and another turn in a developing plotline we commented on last quarter.Please fill out the form below to access the report.

Consider this comparison: in February 2021 ERCOT West Hub (along with others) settled at the market price cap of $9,000/MWh for three days; in February 2022 ERCOT West Hub saw a two day period where prices never rose above $0/MWh. Mild demand coupled with sustained periods of high wind and solar generation created the conditions for this negative pricing event, though these conditions weren’t isolated to only those few days. In fact, by the end of the quarter, West Hub would more than double the number of negative-priced hours than were seen in Q1 the year prior.

One impact of this increasing frequency in negative pricing is rising levels of curtailment, particularly among solar projects which, unlike wind, don’t benefit from
the production tax credit and are less likely to operate below $0/MWh. For example, using the modeled energy in REmap, which tells us how projects could have performed based on underlying wind/solar resource availability, last quarter West Texas solar projects saw anywhere from 20 to 30% of their potential hourly production for a given month fall in negatively priced hours. However, in reality these projects weren’t operating at their potential capacity in these intervals, and either shut down or significantly ramped down production.

Another important angle to consider: whereas for the last few years hourly negative prices at West Hub were evenly split between on-peak and off-peak hours during this time of year, this year saw that balance shift to 60/40 in favor of on-peak hours. The cause for this shift is clear: increasing amounts of solar capacity means that low pricing is no longer just following the production profiles for wind, and is coinciding more regularly with the rise and fall of solar energy.

Looking ahead, as seasons change into summer conditions so too do we expect a change in the volume of negative pricing. An increase and shift in demand– which will steadily move more towards the mid afternoon as air conditioning ramps–and a decline in wind production at the same time should converge to steadily mitigate on-peak negative price frequency. Q2 will likely be a transitional period, with frequency of negative pricing hours remaining high to start before subsiding more materially by the end of the quarter.
