Energy Resource Acquisition: 2010 Request for Proposals from All Generation Sources & Demand Side Resources

Purpose of RFP Filing

Regional growth, the expiration of large purchased-power contracts in coming years and the potential retirement of aging power plants are the principal drivers behind PSE's need for additional power supplies. PSE's latest Integrated Resource Plan, published in July 2009, estimates that the utility will need the equivalent of about 1,600 megawatts (MW) of new electricity supply by winter 2016-17 to meet customers' needs. Since filing its IRP, PSE has refined its resource-need analysis and concluded the resource need is higher than stated in the plan. As a result, PSE filed the 2009 IRP Addendum in late January 2010 , which increases the amount of resources sought in the RFP. The new need was presented at the proposal conference on Jan. 28, 2010.

To help ensure that PSE acquires resources for our customers at the lowest reasonable cost, the Company filed a Request for Proposals from All Generation Sources ("All Source RFP") and a Request for Proposals for Electric and Gas Demand-Side Resources ("Energy Efficiency RFP") (collectively, "RFPs") with the Washington Utilities and Transportation Commission ("WUTC").

Energy Efficiency RFP

The Energy Efficiency RFP seeks to enhance PSE's already aggressive programs for helping customers use less energy. PSE estimates that energy efficiency could lower the utility's power-capacity need by about 500 MW by 2016. By 2029, PSE calculates, customers' energy-saving efforts have the potential to offset the power requirements of 400,000 households – and forestall the need to build four average-sized natural gas-fired power plants. The updated resource plan also identifies 90 million therms of achievable natural-gas savings by PSE customers, enough to satisfy the total gas needs of 108,000 households.

The energy-efficiency RFP invites qualified firms to offer services in 2010 and 2011 that complement or improve upon PSE's existing energy-saving programs for residential, commercial and industrial customers.

All Source RFP

The All-Source RFP asks outside power producers, marketers, and power-plant developers to help PSE procure approximately 1,000 MW of new electricity resources by 2016. While PSE anticipates energy efficiency, renewable power and gas-fired generation will be its dominant sources of new power supply in coming years, the RFP will consider any viable power-supply offering or technology that can be in operation by 2016. PSE will consider various contract arrangements, such as investment in existing power plants, ownership of new plants, or long-term power purchases.
