The Grid Is Not a Tinker Toy
By John A. Charles, Jr.
Rarely has Oregon’s lack of political leadership been as painfully obvious as it is now on the topic of grid reliability.
Most of us take for granted the miracle of electricity. We flip a switch and the lights come on. Computers, air conditioners, smartphones—all powered by the magic of the grid. We don’t care how electricity arrives; we just want it, every hour of the day.
One of the intriguing characteristics of the grid is that electricity must be consumed at the same time it is generated. It cannot be stockpiled the way water can be stored in a tank. As a consumer, you can’t go next door and borrow a cup of kilowatts.
Supply and demand on the grid must be in equilibrium at all times, to avoid blackouts. This makes power generation tricky. Utilities need electricity sources they can count on—known as “baseload” power. They typically use coal, natural gas, nuclear, and hydroelectric generators for this purpose. Those sources with the most operating flexibility—typically gas and hydro—are also used as “peakers,” to alter the power supply so it matches hourly changes in consumer demand.
The Oregon legislature declared war on reliable sources in 2007, when the first “Renewable Portfolio Standard” (RPS) law was passed. The RPS mandated that large utilities procure at least 25% of their power from politically-designated “renewable energy” sources by 2025. The most notable feature of this law was that it disallowed hydro dams built prior to 1995 to count as “renewable” energy—creating the legal fiction that the Columbia River hydropower system did not exist as a clean energy source. The point of this definition was to force utilities to switch to wind and solar.
Legislators doubled the RPS mandate to 50% (by 2040) in 2016. This was referred to by advocates as the “coal to clean” bill. They falsely promoted it as a means to eliminate coal-fired electricity. But the grid doesn’t work that way. Oregon is part of a multi-state network, in which thousands of power sources are being used at any given time. Once on the grid, electricity flows at the speed of light throughout the distribution system, powering millions of toasters, microwaves, and HVAC systems. Coal power is not physically isolated from solar or hydro.
In response to these political mandates, electric utilities are gradually shutting down coal plants in Oregon, Washington, Montana, and Wyoming. Unfortunately, they are proceeding without a clear plan for replacing baseload power. Wind and solar won’t cut it; as “intermittent” sources they fail to produce electricity about 70% of the time.
Oregon’s only coal-fired plant, located near Boardman, is owned by Portland General Electric (PGE). Due to an environmental lawsuit that was settled a decade ago, Boardman is scheduled to close by the end of this year. Electricity forecasters are predicting Northwest power shortages as early as 2020, and deficits of thousands of megawatts later in the decade.
PGE does not have a precise plan to replace Boardman. The utility expects to sign hydro contracts as a transition strategy. But any weather-related power source can disappear quickly, as happened in 2001 when the region experienced a low-water year. The result was a shortage of electricity, and the painful shutdown of the aluminum industry. Some 5,000 jobs in the Northwest disappeared.
PGE also expects to build or buy more wind and solar, coupled with battery storage. But the best utility-scale storage facility in the country can only deliver power for four hours.
We are on the brink of a blackout crisis. Instead of addressing a problem they created—the RPS law—state legislators have wasted the 2020 short session trying to prevent “global climate change” by placing limits on fossil fuel use in Oregon. Even if enacted, this would have no measurable effect on climate, so it is a waste of time and money.
Business leaders and civic groups should demand an end to this insanity. Here’s a short agenda:
First, investigate the possibility of extending the life of Boardman. The facility was designed to run for another 20 years. We should not shut it down unless all of its baseload power can be replaced by other reliable sources, at a reasonable cost.
Second, consider having the legislature refer out a referendum to re-legalize nuclear power. Some of the most cutting-edge research on smaller-scale nuclear energy is being done here in Oregon, but any commercialization will have to take place elsewhere. It’s time for a new conversation on this subject.
Finally, repeal the RPS statute. Operating the grid is complicated enough; mandating the types of power sources utilities can use is only making things worse.

Repeal ALL rules & laws that try to “solve” climate change. AKA: Al Gore’s climate scam.
Steve Wright a long time Administrator of the Bonneville Power Administration, and currently CEO for a large Columbia River electric utility; is saying just as above we are risking black outs…serious amounts of blackouts…how is this good for the children and other people having medical equipment running on electricity.
And What the freak for. If you look at climate temperature for like the Portland area, there is an increase of only about one half Fahrenheit degree since the 1940s using National Weather Service data, and it is very possible this is accounted for by urbanization of the area around the Portland temperature gauge at Portland airport since the 1940s. The biggest named storm in the Willamette Valley is still the Columbus Day storm of 1962, a period when it is thought the globe is going into a cooling phase. Then the biggest floods are like the Christmas Day floods of 1968.
This whole loss of perspective on the trade offs that come from something like Cap and Trade is a corruption of the local and national media complex plus a government and public education system benefiting from alarming folks so they empower and enrich the government class and its politicians.
The way this looniest trend is going you really have to think about buying a gasoline powered back up generator and a couple of weeks worth of gasoline for it. Because the nutcases driving this stuff can’t even be driven from power even when it becomes obvious as in California last Fall – they don’t care if people/constituents suffer substantially.
this is wrong not to refer to the voters , there must be a legal way for people in Oregon to challenge brown on this. She I
has ruined our state . Would love to see people challenge this and tie it up in the courts for years.
