Procurement partners should work with each other and the project owner to determine how and when to announce the deal to the press and general public. In particular, procurement groups should decide if communications staff across organizations will work collaboratively on the announcement or if one or a subgroup of buyers will take the lead.

Sharing success can help inspire other buyers (e.g., other local governments, public institutions, businesses, and universities) pursue aggregated renewable energy purchases, potentially supporting local governments’ communitywide renewable energy goals.

After successfully completing its first aggregated deal, the City of Melbourne chose to share its success and dedicate time and resources to catalyze other aggregated procurements of large-scale renewables in Australia. City officials wrote a case study about aggregated PPAs and published their RFP online to serve as an example to others.

The City of Melbourne then convened a second aggregated procurement group of seven large energy users within the city. This second procurement helped supply 14 shopping centers, nine office buildings, seven educational campuses, and four manufacturing facilities across greater Melbourne with renewable energy. Together, the two deals will reduce the Melbourne community’s greenhouse gas emissions by 5 percent. This case study highlights how local governments can build on a successful aggregated deal to help their community members transition to renewable energy.

The Renewables Accelerator’s City Stories & Videos provides additional examples of how other cities have shared their renewable energy procurement experience.
