NorthWestern to issue RFP for up to 150 MW in Montana

NorthWestern Corp. plans to issue a request for proposals for up to 150 MW to help meet the demand of its Montana customers during peak hours.

The company will seek proposals for power purchase agreements, ownership opportunities, build-own-transfer projects from a bidder's site or engineer-procure-construct contracts to be built on a site owned by NorthWestern Energy, its Montana utility's trade name. In any case, the company is looking for resources that would be available by the end of 2019.

The RFP will be issued on Feb. 13, according to NorthWestern's 2017 RFP web pages. Registration by Feb. 9 for a site visit on Feb. 16 to the 150-MW gas-fired Dave Gates Generating Station (Mill Creek) is required for all engineering procurement and construction bids. A bidder's conference call is scheduled for Feb. 22.

Deadline for the submission of the offers is at 5 p.m. on April 17. A short list notification is possible by June 16, with a successful bidder notification by Oct. 16. More information can be found at

NorthWestern said in a press release it seeks to procure dispatchable electrical capacity and energy that can be delivered to its Montana customers. The company said it encourages vendors of a variety of fuel types and technologies.

Looking further into the future, NorthWestern in its resource procurement plan is calling for hundreds of megawatts of gas-fired generation capacity additions through 2029.

Since the acquisition of its Montana hydroelectric system late in 2014, NorthWestern said it has focused on adding capacity to meet customer needs during times of peak energy demand and for greater capability in balancing intermittent wind generation and other renewable resources.
