Some projects located in one utility’s service territory may be contracted to another utility, as the interconnecting utility and the contracting utility may or may not be the same entity.
- The interconnecting utility is the utility that issues the interconnection agreement and to whose infrastructure the project system is connected.
- The contracting utility (also known as the Buyer) is the utility that signs the REC Contract and purchases the RECs delivered by the system. There are only three contracting utilities: ComEd, Ameren, and MidAmerican.
A project system may be interconnected to Ameren but contracted with ComEd for REC delivery, or vice versa. The Program Administrator determines which utility will serve as the Buyer for each contract. While a batch may contain projects in multiple utility service territories, the Program Administrator will strive to assign contracts to the utility where the bulk of the projects are located but may not always be able to do so because consideration is made to allow each utility to meet its pro-rata share of the Renewable Portfolio Standards (“RPS”) REC targets and available RPS funding. The REC price for each system will be based on the applicable Group for that system’s physical location and not based on service area of the contracting utility.
