Big companies are stepping up their efforts to purchase electricity from new wind and solar farms, providing a much-needed boost to the renewable energy sector, especially as governments face financial pressures and are cutting back on subsidies.
According to recent data from BloombergNEF, sales of renewable electricity through long-term power purchase agreements (PPAs) grew by 35 percent last year. The largest growth was seen in the United States, where tech giants are increasingly securing renewable energy to power their data centers. Nayel Brihi, an analyst at BloombergNEF, highlighted that Amazon was the leading purchaser. He also noted that companies in sectors like chemicals, mining, and raw materials, particularly in developing nations, are significant contributors to this trend.
Markus Krebber, CEO of RWE, one of the leading renewable developers globally, pointed out that his company requires long-term commitments to move forward with new offshore wind projects. At an energy conference in London, he emphasized the importance of having fully contracted capacity, stating that without such agreements, financing costs can escalate rapidly.
In January, Denmark halted all offshore wind auctions after no bids were received for three North Sea wind farms that did not include subsidies. Krebber mentioned that if the power markets are insufficient or the scale is too small, bidders will hesitate, as it’s crucial for them to have bankable projects.
He also expressed concerns that the pace of renewable development might slow down due to higher interest rates, tariffs, supply chain issues, and geopolitical factors. “We are navigating a more uncertain and unstable environment than we did five years ago, which leads us to prioritize risk management,” Krebber said.
The amount of new wind capacity added in Europe fell for the second consecutive year, with a 13 percent drop last year compared to a record high in 2022, according to WindEurope. Meanwhile, the growth rate of new solar farms in the EU experienced a staggering decline of 92 percent last year, noted SolarPower Europe.
Despite these challenges, there is still funding available for new renewable projects if long-term deals are in place. A senior energy banker stated that sectors like technology, food, and agriculture are at the forefront in securing renewable energy agreements.
For instance, Arla, the world’s fifth-largest dairy company, signed five new PPAs last year and plans to rely entirely on renewable energy in Europe by the end of this year. “We could easily purchase energy on the open market, but we want to support the development of wind and solar parks,” said Mia Bredal Duus, Arla’s director of sustainability project management.
Unilever is also looking to grow its number of PPA deals, believing that it will not only expand renewable energy capacity but also provide stable power prices long-term. The company explained that developers depend on large corporations like Unilever to reduce risks and show lenders that their projects are financially viable.
Brihi from BloombergNEF expects the rise in PPAs to continue, driven by the demand from data centers and companies committed to using 100 percent renewable energy, as outlined in the RE100 initiative. He pointed out that while PPAs currently represent a small part of overall renewable energy additions, their significance is likely to rise as government subsidies decrease.
