As a provider of an essential service, we are working to ensure we are here for our customers, our community and our employees as coronavirus impacts the region.

With Governor Inslee’s Safe Start Washington county-by-county phased re-opening approach, PSE is gradually returning maintenance and construction crews back into the field and offices. PSE’s highest priority is the health and safety of our employees and communities. As such, we continue to adhere to current CDC guidance regarding COVID-19 while working in our community.

We are requiring our employees to maintain physical distancing while working in the field and offices. We encourage our customers to do the same when engaging with our employees.

Acquiring Energy

Procuring new energy supply

To meet the anticipated energy needs of our region in the coming years, PSE must acquire new sources of energy. We have several strategies for acquiring additional energy, approaches that meet your long-term demands for electricity and natural gas while keeping your rates as low as possible.

As a leader in renewable energy, we are actively developing additional renewable resources that protect both your pocketbook and the environment.

Another important strategy is to continue helping homes and businesses save energy. Over the next 20 years, our energy-efficiency programs are expected to help customers save more than 500 megawatts of electricity. Those savings are equivalent to the output of four average-sized natural gas-fired power plants.

We also identify new energy resources by issuing formal requests for proposals (RFP). This open-bidding process helps us purchase power, acquire existing power plants and develop new facilities at the most competitive prices.


Our RFP process

Pursuant to Washington Utilities and Transportation Commission rules (WAC 480-107), following the biannual updating of PSE's Integrated Resource Plan, PSE files a Request for Proposals when the plan identifies a resource need within the next three years.
