Key Differences in Risk Management Between Storage PPAs and Traditional PPAs
While both storage PPAs and traditional PPAs are used for managing risks in energy procurement, there are distinct differences in how risks are managed and allocated between these two types.
Traditional PPAs
- Risk Allocation: Traditional PPAs focus on allocating risks such as price, liquidity, volume, credit, and profile risks between the buyer and seller. For example, in a pay-as-produced structure, the buyer bears price, liquidity, and profile risks, while the seller is responsible for volume risks.
- Mitigation Strategies: Traditional PPA risk mitigation often involves financial instruments like hedging contracts to offset price volatility and diversifying energy portfolios to manage volume and profile risks.
- Contract Structure: These PPAs are typically structured with fixed or variable pricing mechanisms over long-term contracts (10 to 25 years) to ensure stable revenue streams for producers and predictable energy costs for buyers.
Storage PPAs
- Additional Risks: Storage PPAs introduce additional risks related to technology performance, battery durability, and dispatch control. These risks include the performance of energy storage systems over time and the ability to optimize energy dispatch and charging strategies.
- Risk Allocation: The allocation of risks in storage PPAs involves ensuring the developer is responsible for the sale of energy and associated costs. The utility typically avoids ownership risks but may face termination risks if the project fails to perform.
- Mitigation Strategies: Mitigation strategies for storage PPAs include robust project design, maintenance plans to ensure system reliability, and contractual structures like capacity-only contracts that shift revenue management back to the developer.
Key Differences
- Risk Complexity: Storage PPAs involve more complex technologies and additional performance risks compared to traditional PPAs.
- Contractual Structure: While both types use PPAs for risk management, storage PPAs often combine elements of PPAs with other contract types (like BTAs) to manage ownership and performance risks.
- Market Dynamics: Storage PPAs face evolving market rules and regulations around energy storage, which can complicate revenue projections and risk management strategies.
In summary, while both types of PPAs are essential for managing energy procurement risks, storage PPAs involve unique technical and performance risks that require tailored risk management strategies focused on technology reliability and market adaptability.
