Sustainable Power Systems Rating Program Launched

Sustainable power systems rating system

Green Business Certification Inc (GBCI) launched the newest green rating system earlier this week – this one is for sustainable power systems.  PEER, as it is called, stands for Performance Excellence in Electricity Renewal, and it evaluates power generation, transmission and distribution systems through the lens of the customer, focusing on efficiency, quality, reliability, resiliency and the environment.

The PEER rating system is modeled after the US Green Building Council’s LEED green building certification program (Leadership in Energy and Environmental Design), and will be managed by GBCI.

“Buildings don’t exist in a vacuum, so integration with other industries, such as energy and power, is crucial if we are to create a more sustainable built environment.  PEER will be a transformative tool for power systems regulation, design and operation,” said Rick Fedrizzi, CEO & founding chair, USGBC, and CEO, GBCI.

“Through LEED, USGBC has created a common language, standard and platform for advancing knowledge, technology and innovation in green building.  It now aims to do the same in the power sector with PEER,” said John Kelly, program lead of the PEER rating system, “and we anticipate similar transformative results.”

PEER Sustainable Power Systems According to a post on the PEER web site, “The PEER rating system helps fill a major gap in the microgrid and smart grid movements, providing an opportunity for power systems to gain competitive advantage by differentiating their performances and demonstrating meaningful outcomes.  In the process, the metrics serve as a tool to accelerate transformation in the marketplace.”

The rating system looks at power systems across four outcome categories, allowing stakeholders to both evaluate and set the standard for system performance that best meets customers’ needs.

  • Reliability and Resiliency: The intent of this category is to ensure the reliable delivery of electricity and reduce injuries, interruptions and power quality issues. The criteria in this category address power quality, supply availability, interruptions, risk mitigation, restoration, redundancy, and microgrid capabilities.
  • Energy Efficiency and Environment
: The intent of this category is to assess the environmental impact of electricity generation and transmission and encourage the adoption of clean and efficient energy. The criteria in this category address energy efficiency of power delivery, air emissions, resource use, renewable energy credits, and power delivery impacts.
  • Operational Effectiveness: The intent of this category is to leverage value gap analysis to identify and eliminate waste. The criteria in this category address electricity costs, asset utilization, load shaping, general operation expenses, capital spending or investment, corrective maintenance and indirect costs.
  • Customer Contribution
: The intent of this category is to assess customer contribution to grid service, investment and innovation. The criteria in this category address customer grid service capabilities, meter data access, tools, choice, incentives and dynamic pricing.

It will be interesting to watch this new rating system and see if it catches on.  For more information, visit the PEER web site at
