Description (excerpt):
Local governments across the United States are setting ambitious goals to transition to renewable energy. Since most municipalities cannot supply 100 percent of their electricity needs with on-site supply alone, they often look to purchase off-site renewable energy. One approach to do this that can provide numerous benefits is buyer-led aggregation.
Aggregation is an innovative yet underutilized approach in which two or more buyers collaborate to purchase energy from a large-scale generation facility.
This guide outlines how local governments can pursue buyer-led aggregated PPAs for utility-scale renewable projects. It includes the benefits of aggregation, off-site procurement options available to aggregation groups, and case studies of five successful aggregated renewables procurements. The guide also presents a seven-step process to guide local governments to pursue an aggregated procurement.
