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

Puget Sound Energy (“PSE”) has filed a motion to withdraw draft Demand Response and All-Source RFPs filed with the Washington Utilities and Transportation Commission (“WUTC”) in dockets UE-200413 and UE-200414 respectively. Currently, the draft RFPs are scheduled for consideration at the Commission’s open meeting on September 10, 2020. PSE filed a petition in these dockets on September 3, 2020 requesting a two week extension. If the extension is granted, the motion to withdraw PSE’s draft RFPs would be considered at the Commission’s open meeting on September 24, 2020.

On May 4, PSE filed with the WUTC draft Demand Response and All-Source RFPs demonstrating a need for new capacity resources within the next four to five years. In late July, PSE completed the process to update its load forecast, which reflects updated economic and demographic assumptions, the effects of the COVID-19 pandemic, and increased conservation from the 2019 Integrated Resource Planning (“IRP”) process. PSE subsequently updated its electric-peak capacity need projection to include the new load forecast, which had the overall effect of reducing the expected capacity need over the next 20 years. PSE does not project a material need for new capacity resources until 2026.

On August 26, 2020 PSE filed an informational update in Washington Utilities and Transportation Commission dockets UE-200413 (Demand Response RFP) and UE-200414 (All-Source RFP), seeking comment from interested parties on the potential withdrawal of its draft RFPs. PSE received a total of eight comments in response to this notification. After careful consideration of the comments, as well as the impact of the F2020 normal peak load forecast on the capacity need, PSE maintains it is in the public interest to withdraw both the draft Demand Response and the draft All-Source RFPs. For more information about the comments received, please see PSE’s petition filed on September 8, 2020 in these dockets. More information about PSE’s decision to withdraw the draft RFPs can be found in the stakeholder updates provided below and in the dockets referenced above.

  • August 12, 2020 Stakeholder Update
  • August 26, 2020 Stakeholder Update
  • September 3, 2020 Stakeholder Update
  • September 8, 2020 Stakeholder Update
  • If PSE’s petition filed on September 3, 2020 in Washington Utilities and Transportation Commission dockets UE-200413 and UE-200414 for a two week extension is granted, the Commission would consider PSE’s petition to withdraw the draft Demand Response and All-Source RFPs at its next open meeting on September 24, 2020. If these requests are withdrawn, PSE intends to integrate targeted demand response into a separate Targeted Demand Side Management (“TDSM”) RFP in September of this year.

    PSE will notify interested parties of the outcome of these dockets once the Commission issues a final order. Notifications will be sent by email to PSE’s stakeholder notification list and will be posted to this webpage. Interested parties may opt in to receive stakeholder notifications by contacting

    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 four 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.

    The following table summarizes the resources PSE received in response to its 2018 Demand Response and All-Source RFPs by resource type and size.
