Home and Commercial Energy Metering Studies

It has been almost 30 years since the Northwest has conducted large-scale studies on how different types of residential and commercial customers use electricity – the Home Energy Metering Study (HEMS), launched in 2018, and the Commercial Energy Metering Study (CEMS), launched in 2019, aim to change this.

Why? An accurate assessment of the electricity use in the region can contribute to becoming more energy efficient, lowering energy costs, planning for future energy supplies, and continuing the reliability of electric service. These studies seek to help the entire region achieve its clean energy goals by more accurately identifying the role of energy efficiency in improving the environment, lowering costs of electric service, and saving money for Northwest electricity customers.

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 studies. The information collected will be completely confidential and no personally-identifying or company-identifying information will be shared.
