“The available resources were essential in facilitating the process on behalf of these communities. . . . the model specification, and guidance of key personnel at the DOE Municipal Solid-State Street Lighting Consortium played a critical role in our process.”

– Jonathan Roberts, Iowa Association of Municipal Utilities

The Iowa Association of Municipal Utilities used Consortium assistance to leverage the buying power of 15 small municipalities with a joint purchase and competitive bid process to buy 1,154 streetlights.
