Basin Electric's 560-MW Pioneer Phase IV Wins ENR Award in Bakken
Pioneer Generation Station Phase IV, a 560-MW gas addition in Williston, N.D., finished on time and $10 million under budget, ENR reports in its 2026 Midwest Best Projects Award of Merit recognition.
Market Impact
Basin Electric Power Cooperative needed new capacity online by summer 2025 to get ahead of projected load growth in the Bakken region, ENR says. The project expands Basin Electric’s existing natural gas facility. Burns & McDonnell served as both lead design firm and general contractor.
The owner chose a progressive EPC model, which let design and procurement start immediately. ENR says that took months off the schedule and gave the owner cost certainty. The team secured land options within a week and bought gas turbines before the total project cost was final. That kept the project’s place in the manufacturer’s production line and avoided a year-long delay.
Field execution was compressed too. Specialized equipment cut through frozen ground so civil work could begin in March 2023, and the first steel structure went up five months later. When a major piece of equipment arrived months late, the team resequenced work and held the completion date. ENR describes the job as a greenfield power plant on a brownfield site, tripling the existing plant’s size. The design unified three different original equipment manufacturer technologies with existing utility infrastructure.
What It Means for Subcontractors
- Civil and earthwork: Civil work started in March 2023 in frozen ground, using specialized cutting equipment. Contractors with winter excavation capacity are positioned for Williston Basin schedules that cannot wait for a thaw.
- Structural steel: The first steel was erected about five months after civil started, which is roughly August 2023 by our arithmetic. Erectors should expect steel to follow quickly behind foundations on compressed schedules.
- Mechanical, electrical and controls: Tying three OEM technologies into existing utility infrastructure on a live site is an interface-heavy scope. Pipefitting, electrical and I&C crews that can work around operating equipment and multiple vendor systems have an edge. ENR does not break out subcontract packages, so this is our inference from the scope described.
- Resequencing readiness: The team absorbed a months-late equipment delivery without moving the finish date. Subs that can shift crews to other work fronts on short notice make themselves useful to the GC.
- Procurement stage: Progressive EPC starts design and procurement before the price is fixed, so subcontract packages may be defined earlier than under traditional bidding. Target Burns & McDonnell, the design lead and GC, early, since ENR names it as the party running the work.
- Next phase: ENR does not name a Phase V, a schedule or any package values. It does say Basin Electric drove this build to meet Bakken load growth. That makes the cooperative the owner to track if further capacity is announced, but no public bid process or portal is cited in the source.
