US solar PPA prices may continue to rise until new supply chains emerge

Prices for power purchase agreements have been rising steadily since the end of last year. According to solar developers, interconnection delays, permitting challenges, and supply chain constraints are likely to keep them high.

Last year marked a significant change in the U.S. renewables landscape, as solar power purchase agreement (PPA) offer prices rose consistently in 2020. Fourth-quarter 2020 prices were 11.5% higher than in the fourth quarter of 2019, for an average price of $30.56 per MWh. In the third quarter of 2021, solar prices rose 14.7% year on year to $33.25/MWh.

These prices were tracked by LevelTen Energy in its quarterly PPA Price Index report. The latest edition of the report lays out the expectation that, until new supply chains emerge for the U.S. solar market, these increases will continue.

Broken down by independent system operator, PJM experienced the highest prices, averaging $37.5/MWh. That was followed by MISO at $35.0/MWh, SPP at $31.9/MWh, ERCOT at $28.0/MWh and CAISO at $29.5/MWh.

Since the trend first emerged, the consistent price increase has been driven by shifting supplies of polysilicon from Chinese suppliers suspected of using forced labor. Other issues include a shortage of PV components and new potential tariffs on solar module imports from Southeast Asia. However, solar PPA prices did not rise as high as many expected, which LevelTen says could be attributed to some developers taking a “wait-and-see” approach, before driving up their prices.

“There’s no denying that it’s currently a seller’s market. But, decisive buyers can use that to their advantage by understanding sellers’ motivations and constraints,” said Michael Casey, director of origination at LevelTen Energy. “For example, sellers are currently asking for emergency exits to be built into PPA contracts to protect themselves against regulatory uncertainty … these are provisions that may have seemed outlandish to buyers before, but they could become the new temporary norm until some of these development challenges are resolved.”

Most developers that LevelTen contacted in creating the report (53%) said they are altering their supply policies by incorporating anti-forced labor provisions into their module supply contracts. Roughly 20% are going further in reporting that they are renegotiating module supply contracts, and nearly 30% said that they are finding new module suppliers.

Despite these new constraints, only 8% of developers reported delaying, terminating, or planning fewer projects. This relative normalcy in the face of change may not hold forever, as respondents highlighted interconnection timelines and costs (89%), permitting challenges (52%), and solar supply chain challenges and constraints (50%) as barriers to achieving the level of solar development the Biden administration is eyeing.

“Solar developers across the U.S. are navigating many challenges,” said Gia Clark, senior director of developer services at LevelTen Energy. “Long interconnection queues tend to put upward pressure on PPA prices, as they create uncertainty around commercial operation timelines and overall project costs. Though MISO solar prices this quarter experienced their first downward trend in a year, it would be unsurprising to see their rising trend resume in Q4.”

Las correcciones de políticas estratégicas pueden generar más ahorros para los suscriptores de energía solar de la comunidad – Solar Energia
May 17, 2022

[…] Precios solares aumentó en 2021, y los precios de la energía solar comunitaria no fueron una excepción. Parte del aumento en el coste se puede atribuir a las largas colas de interconexión, ya que los proyectos enfrentan incertidumbre sobre los plazos y el coste. Los proyectos solares comunitarios deberían tener una ventaja en esta área, ya que Generación distribuida inherentemente alivia la carga colocada en la red y reduce las pérdidas que ocurren cuando la electricidad se transmite a grandes distancias. Debido a este beneficio, los costes solares comunitarios actuales no reflejan con precisión el valor que aporta a la red. […]

Strategic policy fixes can bring more savings to community solar subscribers – The Latest in Solar Power | Clean Energy | Renewable Energy News

[…] Solar prices increased in 2021, and community solar pricing was no exception. Some of the rise in cost can be attributed to long interconnection queues as projects face uncertainty on timelines and cost. Community solar projects should be at an advantage in this area, as distributed generation inherently eases the burden placed on the grid and reduces losses that occur when electricity is transmitted over great distances. Because of this benefit, current community solar costs do not accurately reflect the value that it is bringing to the grid. […]
