The Nuclear “Renaissance”… at -1 (Maybe)

There has been much talk of a “renaissance” of nuclear power in the United States. While I personally am a big fan of nuclear power, in my posts I attempt to cull the reality from the hype. One key concept is that even if a few plants get built, they are not likely to significantly dent the capacity loss from plants being pulled from service out of our current fleet of 104 units.

Vermont Yankee

Recently the state of Vermont decided not to allow the renewal of the license for the Vermont Yankee nuclear plant. This decision was made by the Vermont Senate not the NRC itself (the NRC has allowed all licenses to be extended that have been requested so far, I believe). The NRC originally licensed reactors for 40 years and can provide a 20 year extension; Vermont Yankee went live in 1972 and thus it will not be in use past 2012 unless the license is extended. Per this article, Entergy intends to fight the state decision:

Late Wednesday, the Vermont Senate blocked the company’s application for a 20-year operating license extension for its Vermont Yankee nuclear plant. Entergy said in a statement that the effort to win the renewal, “is far from over.” The power company said it’ll work to prove its case to the Vermont legislature, state officials and the Vermont public. Entergy may be forced to shut down the plant in 2012.

Of course this begs the question as to how Vermont will now get its power; this plant provided 35% of all power (according to the Wikipedia link above) for Vermont in 2006 and certainly losing a fully paid for, base load nuclear station is going to require a lot of expensive replacement power from other sources. Since Vermont is on the east coast and there is a heavy transmission grid there other power sources should be available, but this likely will have a rate impact on the citizens of Vermont when they begin paying a higher price for out of state power.

Entergy and Spinning off Nuclear Assets

The plant is owned by Entergy. Entergy is run by Wayne Leonard, one of the smartest guys in the electrical utility industry, who purchased this plant back in 2002 (here is a link to the original purchase announcement, before it officially closed, back in 2001). It isn’t a “done deal” yet that the plant won’t get re-licensed, but if so, it would be expected that this would be a financial negative for Entergy because they likely assumed that the plant would have been re-licensed (because they are routinely approved by the NRC) when they purchased this asset back in 2002. Entergy is also thinking of spinning off their nuclear plants to shareholders; this is smart because the value of the nuclear assets are impaired by the fact that they are owned by distribution companies; as a stand-alone asset, they can charge whatever the market will bear and the distribution company will have to pay up or go without; when they are part of an integrated utility you can only raise rates so much without causing yourself problems since you own both sides of the value chain.

The state of New York woke up and realized the problems that independent nuclear plants would cause. Per this article:

New York’s utility regulator said on Thursday its staff found Entergy Corp’s (ETR.N) plan to spin off six nuclear power units, including three reactors in New York, to a new company, Enexus Energy Corp, was not in the public interest. The New York State Public Service Commission said in a release it was considering other options, including changes to the transaction to improve the financial stability of the three New York reactors and provide benefits to ratepayers. The staff concluded that the level of debt needed to finance the Enexus spinoff “is excessive when the business risks of this new merchant nuclear plant enterprise are considered,” the agency said.


The re-licensing of Vermont Yankee isn’t a done deal yet. It is likely that Entergy will continue to negotiate with the state of Vermont and they want some sort of additional clean up or concessions to allow the sale to go forward, or a guarantee of some sort of rate reductions below what could be charged as “market” rates. Like the state of New York, the states have to move while they still have some leverage (when the plant owners are changing the license or getting re-licensed by the NRC, which may or may not require state approval) because the Federal Government is pretty much approving everything right now without significant conditions.

Given that the states don’t actually believe that significant new capacity will be coming on line anytime soon, and that renewables haven’t made any sort of significant supply contributions to date, letting these nuclear plants charge whatever the market will bear will have ruinous impacts on utility customers because there is no viable competition on the horizon in terms of significant new plants. There has never been a better time to own a paid-off nuclear plant than right now.

  1. Vermont Yankee is a a very productive infrastructure asset for the region, not alone the state of Vermont. This will affect electricity prices not just in Vermont but throughout the NEPOOL grid.


    Even Canada will see an increase in prices since some or all of the replacement power is likely to come from Hydro Quebec. That means a negative hit on the US balance of trade too.

    Vermont Yankee is about a third of the intended operating reserve for NEPOOL so grid reliability will take a hit too. New combined cycle gas turbines would be the expected response but New England has expensive natural gas so running them on imported petroleum is one possibility too.

    For the owners, a shutdown will likely mean that the plant will be placed in a condition called “safe store” where the fuel is removed from the core and a general, light flush of radioactive systems is performed. That fuel will probably reside in the spent fuel pool for a decade or more. The plant staff will be reduced to a few operators, maintenance men, and security guards.

    The financially interesting issue is what to do with the plant decommissioning funds. These moneys have been set aside from operating revenues and were transferred upon the sale of the plant to Entergy. The return on this trust fund has historically been greater than expected and the costs of decommission have been driven lower with our experience base. When the plant was sold, the IRS tried to grab a bunch of it but I think that was beaten back.

    It is possible that Energy could get a windfall from shutdown although I’m sure they would do better with a license extension and continued operation.

  2. I am tempted to say that Vermonters should be cut off from the electric grid and allowed to freeze in the dark.

    Vermont is the only state that is represented in the Senate by an avowed socialist. But their other Senator is a nasty piece of work too.
