RenewaFi Report: More Pronounced ‘Duck Curve’ in ERCOT Drives Increasing Skepticism of Long-Term PPAs

RenewaFi’s 2023 ERCOT PPA Report features insights from 800+ bids and offers.
Despite the challenging economic climate, RenewaFi market participants matched on PPAs with terms ranging from 5 to 20 years.

A more pronounced ‘duck curve’ in ERCOT pushed offtakers toward increasingly shorter-term PPAs over the course of 2023, according to a new report from RenewaFi, the marketplace for ERCOT renewables. The median term of the 670 offers posted to RenewaFi in 2023 was 12 years, while the median term of the 138 bids was 7 years.

Despite offtakers’ preference for shorter-term PPAs, however, RenewaFi market participants matched on PPAs with terms ranging from 5 to 20 years, with the median term being 10 years. In 2023, RenewaFi facilitated seven matches with an additional match currently pending.

Noam Yaffe, Founder and CEO, said, “2023 was a year of change for the ERCOT PPA market. The ‘duck curve,’ long a characteristic of the CAISO power market, took a much more pronounced shape in ERCOT than in prior years, which likely contributed to the market significantly reducing its valuation of on-peak forward contracts beyond 2029. These trends create an opportunity for energy arbitrage, which will help fuel the growth in storage capacity.”

RenewaFi is adding several storage structures to its marketplace on Monday, January 22nd. These structures will include blocks, tolls, and floor + share agreements.

The report covers PPA trends at each of the major ERCOT hubs in 2023. It includes the following sections:
