PEER can be utilized for a variety of power systems, including: campuses, microgrids, critical infrastructure, an entire city's grid and a utility territory.

How PEER works

Projects can become certified by achieving a minimum set of requirements and score under the PEER rating system. There are four levels of certification, designating how well a project is performing. PEER certification can become a tool with which to demonstrate value to investors, identify opportunities for improvement and implement those (including through clean energy procurement), and drive larger market change.


Registration for all project types: $1,200
Certification: $8,000


The PEER Guide to Certification (PDF, online) leads project teams through the PEER process. This resource includes important information regarding the PEER certification program including the current policies and procedures.
