PacifiCorp has asked vendors to submit bids for demand-response projects across its six-date service territory.
Responses to the request for proposals, which was released Feb. 8, are due on March 15.
The RFP stems from the company's draft 2019 integrated resource plan, which calls for 178 MW of DR by 2029.
While DR is currently a modest resource in the Northwest, it is appearing in IRPs, albeit on the margins, as the regional shift away from fossil-fueled generation to more renewable resources sets the stage for potential capacity shortfalls.
PacifiCorp itself is shopping for more DR than ever before, although the 178 MW request is a small fraction of the 4.3 GW of renewables by 2023 it asked for in a July RFP that included 595 MW of energy storage, 1,823 MW of solar and 1,920 MW of wind (CU No. 1961 ).
An analysis conducted by Applied Energy Group for the company identified plenty of potential DR in PacifiCorp's California, Idaho, Oregon, Utah, Washington and Wyoming service territories—895 MW in summer and 459 MW in winter, according to RFP documents the utility filed Feb. 9 with the Washington UTC [UE-210088].
The analysis identified 163 MW of potential summer peak DR in Idaho, 156 MW in Oregon and 46 MW in Washington. Almost all of Idaho's potential lies in irrigation—149 MW. Residential has the most potential in Oregon and Washington.
Without irrigation in winter, Idaho's DR potential drops to 18 MW, compared to 168 MW in Oregon and 56 MW in Washington. Nearly 70 percent of the potential for all three states is in the residential sector.
Submitted bids must be able to ramp in one hour or less, with not more than one day notice and for at least one event a week. They must provide at least 2 MW in three years or sooner. Bid prices should include operational costs for five years and 10 years. They are due March 15.
Bids meeting the minimum requirements will be grouped based on where and how demand would be shifted and then scored largely based on price, along with qualitative attributes such as targeting underserved communities.
PacifiCorp is most interested in Oregon or Washington programs focused on nonresidential curtailment, irrigation, and residential or small commercial smart thermostats or water heaters, the company states in the filing.
In Oregon, projects must coordinate with Energy Trust of Oregon, which oversees energy efficiency programs for PacifiCorp customers there.
The company plans to select the winning bids by May 20.
