Wind and solar PPA quarterly prices in North America 2023-2024

In the first quarter of 2024, solar PPA prices in North America declined in comparison to the previous quarter, reaching some 51.52 U.S. dollars per megawatt hour. However, North American wind PPA prices increased in comparison with the last quarter of 2023, surpassing 61.5 U.S. dollars per megawatt hour. Generally, the price of power purchase agreements in North America has presented an increasing trend over the last year. The rise of inflation, as well as interconnection queues in the country have contributed to the recent increase in PPA prices.
