Shutting Out Natural Gas Can Destabilize the Electric Grid

It has been an annus horribilis for the nation’s electric utility companies. Deadly storms and wildfires have left hundreds of thousands — and for short periods millions — of electricity customers without power, sometimes for days and weeks.
These destructive weather events have come at a time when utilities are being squeezed from all directions: By customer needs, by activists’ demands, by state regulators, and by the zero-carbon urgency of the Biden administration as expressed in its bill, the Build Back Better Act, to upgrade and overhaul the nation’s infrastructure.
The utilities themselves have set ambitious carbon-emission-reduction goals, but in some cases, they still can’t meet the demands of the government. They are caught between the clear need to harden their infrastructure against severe weather and shuttering their reliable but polluting coal plants and mothballing their dependable gas turbines.
This predicament caused Jim Matheson, president of the National Rural Electric Cooperative Association, which represents hundreds of utilities, mostly small, in rural areas, to ask Congress to make exceptions, or at least to understand that things can’t be changed overnight. In a letter to House Committee on Energy and Commerce Chairman Frank Palone (D-N.J.) and ranking minority member Cathy McMorris Rogers (Wash.), Matheson said there was concern with the Clean Electricity Performance Program (CEPP) part of the bill.
“The CEPP’s very narrow, 10-year program implementation window is unrealistic. The electric co-ops have existing contractual obligations and resource development plans that extend for several years, if not decades. Many of those plans continued deployment of a diverse set of affordable, clean electricity sources, but not all those plans align with the CEPP. …. The narrow implementation window also limits our ability to take advantage of technologies like energy storage, carbon capture, or advanced nuclear, which are unlikely to be deployable in the near term,” Matheson said.
The predicament of utilities is that there is no reliable storage and that the two principal sources of renewable power, wind and solar, are subject to the vagaries of weather. During Winter Storm Uri, which hit Texas last February, solar, along with all other sources of energy, froze under sheets of snow and ice. The result was disaster and heavy loss of life.
In that instance, gas didn’t save the day: Lines and instruments froze, and what gas was available was sold at astronomical prices.
The lesson was clear: Prepare for the worst. That lesson was repeated in a series of hurricanes, including devastating Ida which plunged parts of Louisiana into the dark for more than a week.
If the lesson hasn’t been grasped in the United States, it is being repeated in Europe right now. A unique wind drought that lasted six weeks has left the European grid reeling and has thrown Britain into a full energy crisis.
The issue is not that alternative energy — wind and solar for now — isn’t the way to go to reduce the amount of carbon spewing into the atmosphere. Instead, it is not to destabilize what you have by prematurely taking gas offline.
Gas has certain useful qualities not the least of which is that it can be stored. Storage is the bugaboo of alternative energy. Batteries are good for a few hours at best and the other main way of storing energy, pumped storage, requires large expenditures, substantial engineering, and a usable site. It requires the creation of a big water impoundment, which will provide hydro when extra power is needed. It works, it is efficient, and it isn’t something that you build in a jiffy.
I have spent half a century writing about the electricity industry and when it comes to decarbonization, I can say that while many in the industry were doubtful about global warming at one time, the industry now is committed to eliminating carbon emissions by 2050.
The joker is storage or some other way of backing up the alternatives. That may be hydrogen, but a lot of research and engineering must take place before it flows through the pipes which now carry natural gas. Likewise, for small modular reactors.
The Economist, pointing to Europe, says that the Europeans have destabilized their grid by failing to prepare for the transition to alternatives, triggering a global natural gas shortage. Gas should be used sparingly and treasured. The trick is to throw out the bath water and save the baby.
