- Nuclear plant closures in Ohio and Pennsylvania will have significant negative impacts on the environment and the regional economy
- Closure of the plants would reverse emissions benefits gained over the last 25 years from all renewable generation in the region; total zero-emission generation in region might not return to current levels until 2032.
- A new report highlights potential for higher electricity costs for local residents, lower GDP, and fewer jobs in the region.
- Some advocates for closing nuclear plants in Ohio and Pennsylvania claim that renewables can make up the difference. This is incorrect as both solar and wind power are highly variable. The majority of lost power generation capability would be made up, if needed, by natural gas plants.
The announced closure of four nuclear power plants in Ohio and Pennsylvania will have severe environmental and economic impacts, according to a new report released on 4/16/18 by The Brattle Group.
Specifically, these closures would likely result in an increase of over twenty million metric tons of CO2 emissions, tens of thousands of tons of incremental air pollutants, and significantly higher electricity costs to consumers. It would also put hundreds of millions in GDP and thousands of jobs at risk for residents across Ohio, Pennsylvania and the broader region.
The report, based on prior studies of the impacts of nuclear plants in Ohio and Pennsylvania, estimates that the combined impact of closing the Beaver Valley Power Station (PA), Davis-Besse Nuclear Power Station (OH), Perry Nuclear Generating Station (OH) and Three Mile Island Nuclear Generating Station (PA) will:
- Increase annual CO2 emissions by over 20 million metric tons, equivalent to 4.5 million cars on the roads and potential social costs of over $900 million per year;
- Increase annual emissions of harmful air pollutants such as SO2, NOX and particulate matter by tens of thousands of tons, with potential social costs of $170 million per year;
Increase annual electricity costs by as much as $400 million annually for Ohio residents and $285 million for Pennsylvanians;
- Put more than 3,000 direct jobs at risk, as well as thousands of additional secondary jobs;
- Eliminate tens of millions of dollars in local tax revenues.
The increase in CO2 and several harmful air pollutants due to these closures will be a major setback to the region’s efforts to reduce emissions. In 2017, these four nuclear plants provided one and a half times as much zero-emission energy as the wind and solar resources across the entire PJM region. (see chart below)
Some advocates for closing nuclear plants in Ohio and Pennsylvania claim that renewables can make up the difference. This is incorrect as both solar and wind power are highly variable. The majority of lost power generation capability would be made up, if needed, by natural gas plants.
As western Pennsylvania and eastern Ohio are centers of natural gas production, due to the use of fracking drilling methods, the construction of these plants near these resources would inevitably be attractive to investors.
Potential use of load following to support renewables
There is an element of the nuclear industry, especially among developers of small modular reactors and advanced designs, that are building in “load following” for the plants. Most large nuclear plants, especially those built in the 70s 80s, run at 100% capacity all the time.
Full size nuclear power plants can do load-following over a 24 hour period. Nuclear power plants operating in the load-following mode follow a variable load program with one or two power changes every 24 hours. The load pattern is determined by the grid operator and the utilities, depending on the power demand and the maneuvering capabilities of the plant.
Load following would allow these reactors to generate electricity at lower levels of utilization during the day, if wind and solar are putting electricity into the grid, and at higher rates at night, or when weather is a factor, etc. In either case, the nuclear plants can have the key role of keeping the grid stable to address the variable nature of renewables.
Role of the PJM Interconnect
The PJM is the largest electricity market in North America, covering all or part of 13 states including Ohio and Pennsylvania, and spanning from Illinois to New Jersey and Virginia.
The loss of these plants would quickly reverse the environmental benefits of all the PJM wind and solar resources developed in the region over the past 25 years – benefits which were supported with billions of dollars of customer and taxpayer investment through renewable energy credits and federal tax credits.
“As this report makes clear, policymakers should take note of the critical environmental and economic contributions of our nation’s nuclear plants, especially where their continued operation is threatened,” noted Brattle Principals and study authors Drs. Dean Murphy and Mark Berkman.
“Any discussion of Pennsylvania’s and Ohio’s energy futures must recognize the significant environmental and economic risks associated with allowing these four plants to close. The impending closures indicate a significant concession in their clean energy commitments.”
Additional findings regarding the impact of these closures from the Brattle report include:
- An electricity price increase of up to $2.43/MWh and $1.77/MWh for Ohio and Pennsylvania residents, respectively (not accounting for any financial support the plants might need to continue operating);
- Another 15 years, at the current renewable growth rate, for the region to return to the level of zero-emissions generation in 2017.
“Thousands of lost jobs, major hits to local tax revenues, higher electricity costs for consumers, and more harmful pollutants – any lawmaker should take steps to avoid such a situation,” said Nuclear Matters Advocacy Council Member and former Senator Judd Gregg (R-NH).
“It is imperative that we act to prevent the closures of these four nuclear plants which contribute needed diversity to Ohio and Pennsylvania’s overall energy supply and provide residents a dependable power source in extreme weather situations.
Following Vermont Yankee’s shuttering in New England, we saw devastating effects. The loss of tax revenues forced local officials to make major budget concessions to the detriment of their residents, including cutting their municipal budget by 20 percent, drastically reducing police services and raising their property taxes by 20 percent.
Furthermore, in the year following the closure, carbon emissions increased by 2.5 percent due to nuclear energy being replaced by emission producing sources. It would be nothing short of irresponsible to allow the people of Ohio and Pennsylvania to share a similar fate.”
“If these plants close, the livelihoods of thousands of Ohio and Pennsylvania residents will disappear. The over 3,000 highly skilled individuals directly employed by these sites will leave to seek employment at other facilities still operating around the country,” said Lonnie Stephenson, President of the International Brotherhood of Electrical Workers.
“In total, thousands of jobs that directly or indirectly rely on the nuclear industry in this region will be lost. Positions at nuclear plants are good, well-paying jobs for hardworking residents, and without them the fabric of these communities will be torn apart.”
About the Report
“Impact of Announced Nuclear Closures in Ohio and Pennsylvania” was prepared for Nuclear Matters by Dr. Dean Murphy and Dr. Mark Berkman of The Brattle Group.
This report follows the recently announced planned closures of Exelon’s Three Mile Island and FirstEnergy’s Davis-Besse, Perry and Beaver Valley plants, a decision the companies attribute to low power prices in wholesale markets and the lack of state and federal relief.
To develop the collective estimates outlined in the report, The Brattle Group drew from previous work estimating the impacts that the loss of the Ohio and Pennsylvania nuclear plants would have on electricity prices and emissions:
“Ohio Nuclear Power Plants’ Contribution to the State Economy” (April 2017) and “Pennsylvania Nuclear Power Plants’ Contribution to the State Economy” (December 2016).
This latest report compares the results of these most recent previous studies with sensitivity cases in order to outline various approximations.
