IN Brief:
- US Department of Energy Order 202-26-49 requires Craig Unit 1 to remain available from 27 September through 25 December.
- Southwest Power Pool is directed to use economic dispatch and call the unit only during hours necessary to address the emergency identified by the department.
- The order extends plant availability rather than requiring continuous generation, separating readiness from actual electricity production.
Craig Station Unit 1 in Colorado must remain available for another 90 days under a new US Department of Energy emergency order taking effect on 27 September, while actual generation is limited to periods considered necessary under the department’s reliability determination.
Order 202-26-49 runs through 25 December and directs Tri-State Generation and Transmission Association, Southwest Power Pool, Platte River Power Authority, Salt River Project, PacifiCorp, and Public Service Company of Colorado to take the measures required to ensure Unit 1 remains available.
US Department of Energy (DOE) issued the order on 25 September under Section 202(c) of the Federal Power Act. Southwest Power Pool is directed to employ economic dispatch and call on Craig Unit 1 only during hours necessary to meet the emergency identified in the order while taking steps to minimise costs to ratepayers.
The wording distinguishes plant availability from continuous operation. A generating unit can remain staffed, maintained, fuelled, and technically capable of starting without producing electricity in every hour. Dispatch remains dependent on system conditions and the requirements established by the emergency order.
Craig Unit 1 had been scheduled to retire at the end of 2025. Federal emergency orders subsequently required the unit to remain available, with the immediately preceding order running from 29 June through 26 September 2026. The latest order takes effect as that period ends.
The September decision therefore represents another temporary extension of operating availability rather than a new generating project or a permanent revision of the plant’s long-term status. Equipment and supporting operations have to remain in a condition that permits the unit to run when required throughout the new order period.
Maintaining an older thermal unit in a ready state carries obligations even when it generates infrequently. Boilers, turbines, generators, cooling systems, electrical protection, controls, emissions equipment, fuel systems, and other plant assets must remain capable of supporting operation, while appropriate maintenance and staffing arrangements have to continue.
Economic dispatch is intended to prevent availability from becoming an instruction to run irrespective of system conditions. If other resources can serve demand reliably at lower cost during a particular interval, the order does not require Craig Unit 1 to displace them solely because the plant has been retained.
The difference also affects fuel use and emissions. A coal unit held available but dispatched relatively infrequently has a different operating profile from one running continuously at high output. Actual fuel consumption and emissions during the order period will depend on how often the plant is called, the duration of each run, and the loading at which it operates.
Section 202(c) provides federal emergency authority for temporary measures affecting electricity supply under specified conditions. Order 202-26-49 is explicitly time limited, with an effective period ending on 25 December rather than creating an indefinite requirement for Craig Unit 1 to remain online.
The department’s stated basis for the action is an emergency reliability determination affecting the relevant western grid region. That determination is the federal rationale for the order; it does not establish how frequently Southwest Power Pool will actually need to dispatch the plant over the three-month period.
The operational question is whether other resources can cover demand, outages, weather effects, transmission constraints, and generator unavailability without requiring Craig Unit 1. The wider system can draw on other thermal generation, hydropower, storage, imports, demand response, and transmission capacity, although each resource has different limits.
Batteries can respond rapidly but remain constrained by energy duration and state of charge. Transmission can bring power from another region only where capacity and generation are available. Hydropower depends on water and reservoir conditions, while other thermal generators carry their own fuel, operating, and maintenance requirements.
A large coal-fired generator can sustain output for long periods but cannot necessarily move from shutdown to full generation as quickly as storage or some gas-fired assets. Keeping it available as an emergency resource therefore requires operators to consider start times and notice periods alongside the probability that the unit will be required.
Successive temporary orders create an unusual maintenance and planning environment for a plant that had been moving towards retirement. Closure normally allows fuel procurement, staffing, contracts, maintenance schedules, and operating arrangements to wind down against a defined end date. Continued short-term availability requires at least part of that process to remain open.
The immediately preceding Craig order covered the period through 26 September. The new order begins the following day and extends the availability requirement through Christmas, while retaining the instruction to use economic dispatch rather than continuous generation.
The distinction will define the unit’s actual contribution over the next three months. Craig Unit 1 must remain capable of operating, but the amount of electricity it ultimately produces will depend on how often Southwest Power Pool determines that the conditions described in the federal order require it to run.
