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.

 

2020 Demand Response and All-Source RFPs Update

On October 15, 2020, the Washington Utilities and Transportation Commission (“WUTC”) held an open meeting in which it granted a motion from Puget Sound Energy (“PSE”) to withdraw its draft 2020 Demand Response and All-Source RFPs in dockets UE-200413 and UE-200414, respectively. Consistent with the requirements of the Commission’s Final Order in these dockets, PSE must file its next draft All-Source and system wide electric Demand Response RFPs no later than April 1, 2021. The full text of the Commission’s Final Order may be found in the WUTC dockets referred to above.

PSE submitted the motion on September 8, 2020, and has been providing stakeholders with periodic updates, which can be found in the links below and on the WUTC web site in the dockets referenced above.

  • August 12, 2020 Stakeholder Update
  • August 26, 2020 Stakeholder Update

    2018 Demand Response and All-Source RFPs Update

    PSE received nearly 100 proposals in response to its 2018 All-Source and Demand Response RFPs from a variety of resource alternatives. This is the largest response to a PSE All-Source RFP to date. Many proposals included multiple offer options with variations in pricing, offer structure, term start and duration, and transmission delivery points. Some proposals offered hybrid options, pairing storage with wind or solar resources.

    So far, PSE has issued three press releases announcing the execution of contracts from the 2018 RFP. The RFP process remains ongoing. PSE will update this site if and when new resources are contracted.
