đCOMMENTARY: Centralia Plant Saved by Gas Conversion â But Is It Enough to Prevent Regional Energy Crisis?
Many in our state are probably too busy dealing with the effects of the latest âatmospheric riverâ to think about how winter will soon bring its own weather challenges.
State lawmakers need to be thinking about it, however. A stretch of sub-freezing temperatures could leave our regionâs energy grid struggling to handle the soaring demand for electricity, especially if itâs a cold spell like we had in mid-January 2024.
That brought a near-blackout â what the power industry calls a ânear reliability eventâ â over several days while temperatures dropped as low as 16 degrees in Seattle and 12 in Portland.
The pressure on the grid is about to increase. At the end of this month, nearly 1,200 megawatts of capacity will be lost when a pair of anti-coal state laws take full effect. According to the Northwest Power and Conservation Council, itâs enough to power more than 935,000 homes, which translates to a significant number of Washingtonâs 8.1 million residents.
More than 60% of this power loss is tied to the only coal-fired power plant in Washington, operated by TransAlta in Centralia, which must cease its remaining generation to comply with a law passed in 2011. But fortunately, that facility just received a new lease on life â and Iâll get to that good news in a moment.
The remainder is generated by the Colstrip coal plant in southeastern Montana and has been part of the energy portfolios for two private utilities in our state. Itâs going away due to the so-called âclean energy transformation actâ forced on our state in 2019 by Democrats at Jay Insleeâs request, no doubt to aid his short-lived, climate-based presidential ambitions.
The loss of these 1,175 megawatts creates a power-supply shortfall in our region for 2026, according to an evaluation provided recently to the state Utilities and Transportation Commission and state Department of Commerce.
This shortfall will not only strain service for existing customers, but it will also hinder our ability to attract new businesses to the area. Without sufficient power to meet current demand, we canât realistically support additional economic development.
At the same time, the demand for electricity in the Northwest is increasing due to more electric vehicles, more air-conditioning systems and the growing number of data centers. The evaluation shared with the state predicts the regional power shortfall will reach 8,700 megawatts by 2030, yet power projects under development wonât provide more than 3,000 megawatts of new capacity.
That will leave nearly two-thirds of the demand gap unfilled. No wonder the report concludes âthe rate of new resource additions required to meet resource adequacy needs in the next five years is unprecedented.â Itâs a nice way of saying weâd better get going like never before on the development and deployment of new power sources if the supply of electricity is going to have any chance to keep up with the anticipated demand.
What kind of power? Wind, solar and batteries make only âsmall contributions,â the evaluation notes. During a multi-day cold snap when hydropower generation is low, and when solar and wind-power generation is almost nonexistent, natural gas is the most reliable source.
Speaking of reliability â with new leadership in the executive branch, maybe we can have a serious discussion about nuclear power. Senate Republicans have monitored the development of small modular reactors and other technology that address the familiar but overblown concerns about this form of energy, which is carbon-free like wind and solar but reliable like natural gas.
That brings me back to the Centralia power plant. TransAlta announced on Dec. 9 it would convert the facility to generate power using natural gas instead of coal. What looked like retirement has suddenly turned into a second chance that will continue until the end of 2044, when the anti-gas part of Insleeâs 2019 law gets in the way.
As senator for the legislative district that has been home to the Centralia power plant since it went online almost 55 years ago, I appreciate the teamwork that led to this news. Itâs an unexpected Christmas gift for Centralia, Lewis County and the surrounding area from an economic standpoint, and a big deal for our state and region from an energy standpoint.
That said, the gas-fired plantâs output is expected to be 700 megawatts, down from the coal-fired 730 or more being generated now. Also, the conversion is projected to keep the Centralia plant from rejoining the regional energy grid until late 2028.
The 592 megawatts of coal-fired Montana power also wonât be fully replaced once it stops flowing to our state at yearâs end. Puget Sound Energy will pull from a new southwest Montana wind farm that generates an estimated 97 megawatts base and has a high-wind maximum of 248 MW. Spokane-based Avista will look west to its Rattlesnake Flat wind farm in Adams County to get an estimated base output of 50 MW with a peak of 160.
This means the coal ban Democrats handed to Inslee on a party-line vote will instantly cut base capacity by 445 MW. Meanwhile, the law that is ending TransAltaâs coal-based generation will put our region on even thinner ice for three long years â or three more winters, if you prefer.
A more recent report from a separate electrical-industry organization predicts the demand for power in our part of the country will be up 9.3% this winter compared to a year ago. Could there be a worse time to see 935,000 householdsâ worth of electrical capacity come off the grid?
Ideology wonât heat your home. The people of our state deserve an energy policy that prioritizes reliability and affordability, so they donât have to worry about a Democratic power blackout the next time we have an extended cold spell. Thatâs how our state does better.
