Home and Commercial Energy Metering Studies

End Use Load Research

The Northwest has not conducted large-scale studies on how different types of residential and commercial customers use electricity on a daily basis for almost 30 years – the Home Energy Metering Study (HEMS) and the Commercial Energy Metering Study (CEMS), both launching in 2019, aim to change this.

Why? An accurate assessment of the electricity use in the region can contribute to reduced energy use, lower energy costs, use of renewable energy, displaced harmful air emissions from power plants, and continued reliability of electric service.

Why now? A need for a better understanding of electricity in the region has grown with changes in, electric appliances, heating and cooling systems, water heating, and newer electricity uses like LED lighting and electric vehicles.

What’s involved? Over 400 Northwest households and approximately 100 commercial buildings will eventually be metered for the study.  The information collected will be completely confidential and no personally-identifying information will be shared.  

Who’s involved? A group of utilities and regional organizations came together to collaborate on this long-term Northwest residential and commercial study of electricity use. This group includes Avista Utilities, Bonneville Power Administration, Clark PUD, Energy Trust of Oregon, The Northwest Power & Conservation Council, PacifiCorp, Portland General Electric, Puget Sound Energy, Seattle City Light, Snohomish PUD, and Tacoma Power.

The Northwest Energy and Efficiency Alliance (NEEA), a non-profit organization based in Portland, Oregon, will oversee and conduct both studies for the next several years.

In the end, this study seeks to help the entire region achieve its clean energy goals by more accurately identifying the role of energy efficiency in improving the environment, providing better electric service, and saving money for you and all Northwest electricity customers.
