Role of EPC Agreements in Energy Storage Projects
Engineering, Procurement, and Construction (EPC) agreements play a crucial role in energy storage projects, particularly for utility-scale battery energy storage systems (BESS). These agreements are designed to streamline project development by bundling engineering, procurement, and construction into a single contract. Here’s how EPC agreements contribute to energy storage projects:
Key Features and Benefits
- Comprehensive Responsibility:
- Full-wrap, Turnkey EPC Agreements: In these models, the EPC contractor assumes full responsibility for all aspects of the project, including engineering, equipment procurement, construction, commissioning, and testing. This approach provides a single, creditworthy counterparty who ensures all project deliverables are met, which is often preferred by project owners and lenders.
- Risk Allocation: By having one entity responsible for the entire project lifecycle, risks are centralized, making it easier to manage potential issues such as delays, equipment failures, or performance deficiencies.
- Cost and Risk Management:
- Owner-Supplied Equipment: In some cases, projects may use owner-supplied equipment (e.g., batteries) to reduce procurement costs. However, this requires detailed contractual provisions to allocate responsibilities between the owner and the EPC contractor regarding equipment delivery, risk, warranties, and installation.
- Performance Guarantees and Liquidated Damages: EPC agreements typically include performance guarantees and provisions for liquidated damages if the project fails to meet specified performance standards.
- Regulatory Compliance and Environmental Considerations:
- Permitting and Environmental Reviews: Owners are often responsible for project permitting and environmental compliance. Utilities may handle these aspects for projects developed on utility-owned sites.
- Decommissioning and Disposal: EPC agreements should address who is responsible for decommissioning and disposing of hazardous materials like lithium-ion batteries at the end of their life cycle.
- Adaptability to Emerging Conditions:
- COVID-19 and Supply Chains: EPC agreements should consider factors like supply chain disruptions or regulatory changes that could impact project timelines and costs.
Challenges and Considerations
- Financing and Creditworthiness: While equity financing is common for BESS projects, full-wrap EPC agreements are preferred when project finance lenders are involved, due to the clarity they provide on creditworthiness.
- Customization and Negotiation: EPC agreements require detailed negotiation to address unique project needs and risks, including performance guarantees, warranties, and testing procedures.
Overall, EPC agreements are essential for structuring energy storage projects efficiently, ensuring compliance, managing risks, and streamlining development processes.
