The UK's solar power market is facing a unique challenge: a price discrepancy that's hindering the growth of Power Purchase Agreements (PPAs). This issue is causing a slowdown in European PPA deals, according to industry experts. The problem lies in the way developers and customers approach pricing. When developers quote a price, customers often compare it to a lower price forecast from a consultant, leading to a significant discrepancy. This discrepancy highlights a fundamental misunderstanding of risk and upside potential in the market. As a result, the central case price doesn't align with the needs of both parties, creating a barrier to deal-making.
The solution, according to industry professionals, lies in early involvement and alignment on risk. Stella Mavrommati, a senior associate at CMS, emphasizes the importance of addressing risks early in negotiations to avoid complexity. Ross Irvine, a senior manager at EDF UK, agrees, highlighting the benefits of early involvement in facilitating agreements and finding simple, flexible solutions. This approach is particularly relevant for new build projects, where grid connection delays are a significant concern.
The market is also shifting towards operational PPAs, which are simpler and shorter-term. This shift is driven by the desire to avoid the risks associated with new projects, especially in the UK, where the Contracts for Difference (CfD) scheme competes with PPAs. Operational assets can plug the gap, ensuring the energy transition is not just about new assets but also about maintaining existing ones.
However, the market is not without its challenges. Increasing negative pricing periods and power market volatility are significant concerns. Mavrommati suggests a range of approaches to address these issues, including setting caps on negative pricing hours or negotiating floors. However, Peyton argues that these factors are less significant in the context of long-term fixed deals, as the seller is not obligated to stop selling when prices are high.
Despite this, energy storage, particularly co-located with generation assets, is emerging as a solution to negative pricing. Island Green Power, for example, uses co-located sites to share land and grid connections, reducing costs and complexity. Energy storage lowers risk but adds complexity, and financial agreements around volatility are becoming more common.
In conclusion, the UK's solar power market is navigating a complex landscape of pricing, risk, and market dynamics. While challenges exist, industry experts are optimistic about the future, particularly with the emergence of financial structures that address volatility and risk. The key to success lies in early involvement, alignment on risk, and a focus on simplicity in financial agreements.
