Energy Storage Contracts & PPAs

Energy Storage Contracts & PPAs

May 31-June 1, 2023 | Denver, CO and Online

“Seminars provide a high-level overview for current industry challenges.” Manager of Power Supply, Wolverine Power Cooperative

“Simply superb course.” Project Manager, Soltec (USA)

In the electric system, energy storage is a technology like no other because of the multiple, essential functions it performs as a generation resource, as load, and as transmission or distribution infrastructure.  Consequently, the structure of power purchase agreements (PPAs) employed for more traditional generating facilities do not necessarily translate to energy storage, or the PPA lacks flexibility to accommodate multiple uses. Therefore, when negotiating and forming an energy storage offtake agreement, it is critical for all parties to understand the ways in which the storage system will be used.

This storage course covers the key issues and contract provisions that need to be considered when negotiating storage projects. The course will help keep you abreast of the importance of energy storage and how to undertake necessary initiatives in a practical and manageable way. 

Learning Outcomes

  • Review the key issues and contract provisions for storage projects
  • Explain contract negotiations, contracting parties and managing operations
  • Evaluate how a stuttering supply chain and clogged interconnection queues influence the performance components of storage contracts
  • Examine the energy storage functions as they relate to contracts
  • Discuss how the various policy and institutional drivers for energy storage need to be addressed in contracts
  • Identify how the storage-specific aspects of the Inflation Reduction Act (IRA) require new contractual provisions
