European companies are increasingly using power purchase agreements to shield themselves from electricity price spikes, marking a shift from their traditional role as a tool for meeting sustainability targets, Jonathan Bruegel, analyst at the Institute for Energy Economics and Financial Analysis, said in a note on Tuesday.
The change has accelerated since the US and Israel attacked Iran on Feb. 28, with day-ahead electricity prices during periods of market stress reaching 120-150 euros ($139-$174) per megawatt-hour in Germany and Italy.
Gas-fired generation sets the marginal electricity price for a substantial share of hours in both markets. Disruptions around the Strait of Hormuz have pushed up European gas prices, feeding through to wholesale power markets and prompting companies to accelerate PPA deals, including some previously stalled agreements.
European PPA prices currently range from about 60-85 euros/MWh, roughly half the spot-market prices seen during stress periods.
The shift is also changing contract structures. Companies are increasingly seeking five- to 10-year agreements with price floors, ceilings and indexation clauses, rather than the long-term fixed-price contracts traditionally associated with sustainability procurement.
Price floors of 50-55 euros/MWh can protect developers if gas prices fall, while ceilings of 90-100 euros/MWh give buyers greater budget certainty. Some developers are also leaving 30-40% of project output exposed to spot markets to benefit from higher prices.
The new focus on price risk is driving demand for more sophisticated PPAs, including contracts that distinguish between day and night, combine solar, wind and storage, or provide storage-backed baseload-equivalent power. Such structures aim to cover periods when electricity prices are highest rather than simply match renewable generation.
Developers, however, remain cautious about locking in prices below current spot-market levels. A PPA at 75-85 euros/MWh could mean foregoing significantly higher spot-market revenues.
Project lenders are also demanding stronger revenue protections, creating a mismatch with buyers seeking shorter contracts. The European Union's electricity market reforms, including two-way contracts for difference, could further encourage developers to seek state-backed revenue certainty.
The shift is likely to persist beyond the Iran conflict, as Europe's continued exposure to gas prices leaves companies vulnerable to future energy shocks.
PPAs are increasingly being viewed as an energy-security and financial-risk management tool, rather than solely a sustainability instrument.
