ACCC Large Scale Aggregation Cohort

In September 2020, the American Cities Climate Challenge (ACCC) Renewables Accelerator, jointly led by Rocky Mountain Institute (RMI) and World Resources Institute (WRI), launched a Large-Scale Renewables Aggregation Cohort to help local governments join forces with other buyers to procure large-scale renewables at economies of scale.

Over the next six months, the Solar Power Purchase Agreement (SPPA) Working Group will be participating in the ACCC Renewables Accelerator’s Large Scale Renewables Aggregation Cohort. This cohort will provide the working group with education, best practices, and model documents on aggregated large-scale renewable procurement. Aggregation presents a way to access many benefits of large-scale renewable energy that most local governments would not be able to access on their own.

There are many benefits of aggregation including: (1) aggregated purchases have a bigger impact, (2) aggregated deals have better economics and prices, (3) aggregation lowers risk, and (4) aggregation creates positive network effects and compelling communications. Partnering with others on an aggregated procurement will enable us to meet our goals while supporting the development of a new utility scale renewable energy project more cost-effectively.
