A Public Service Commission
hearing in Missoula a week or so ago produced an odd and somewhat heated
exchange between John Hines, the vice-president for supply at Northwestern
Energy, and Monica Tranel,
an attorney representing the Montana Consumer
Counsel. Hines was trying to convince the PSC (and the public in attendance)
that Northwestern should be allowed to purchase a bunch of power dams to the
tune of some $900 million, and Tranel was having none of it. Too much money, she
said, and ultimately it would be the consumers who would have to foot the
bill.
Now I don’t know much about
putting a price tag on a power dam, let alone a whole slew of them, so I don’t
know whether $900 million is too much, too little, or just about right, but I
do appreciate the fact that some part of that money is intended to buy a kind
of insurance that will protect Northwestern’s ratepayers from the adverse
impacts of future climate change policies.
Here’s the way it works.
The EPA, operating under its Clean
Air Act authority, will soon be coming out with regulations to limit carbon
emissions from both new and existing power plants (the standards for new plants
have been in the works for some time now). Although the details remain to be seen, these regulations will almost certainly raise the cost of
generating electricity at coal fired power plants (and possibly at natural gas
fired plants as well). The corollary is that power dams, which have no
emissions, will have a distinct competitive advantage over coal and natural gas
and as a result their value will rise.
That means that anyone (like Northwestern) wanting to buy a power dam
will have to pay something extra for the privilege of avoiding the cost of
complying with carbon regulations. Of course Northwestern is not going to pay
that extra dough out of the goodness of its corporate heart. No, it is going to
ask the Public Service Commission to pass on to its rate payers the cost of
owning the dams, including the premium attached to the fact they don’t emit
carbon.
That’s the downside. The upside
is that if it owns the dams, Northwestern is not going to have to go out on the
market, buy electricity from those costly coal fired plants, and pass the cost
of that pricey electricity on to ratepayers.
But one way or another, the
result of carbon regulations is that rate payers are going to pay more. The
question is: how much more? And what’s the best way to deal with this
situation? Is it cheaper for consumers to incur the extra cost of buying the
dams in order to avoid buying the pricier electricity resulting from carbon
regulations? Or would it be cheaper not to buy the dams and instead pay for
more expensive electricity at some point in the future? Northwestern obviously
likes option one. No one knows with certainty how much the regulations will
raise the price of electricity, but Northwestern appears to believe that the
price increases are likely to be large enough to justify paying extra for the
dams. Whether they are right about that or not is a legitimate question, and
it’s the question the Public Service Commission should be asking.*
And here’s where the Consumer
Counsel comes in. Because if I heard Tranel correctly,
she was saying that in buying the dams, Northwestern shouldn’t pay any premium at all to avoid the cost of controlling
carbon emissions. And she implied
that if that means that Northwestern can’t complete the purchase, it will be no
skin off the company’s nose: After all, she said, if the company has to pay
more for electricity after the carbon regulations take effect, it can always go
to the Public Service Commission and arrange to pass the extra cost on to rate
payers.
Well yeah, but doesn’t that beg
the question? Doesn’t it assume that
consumers will be better off if, after the regulations take effect,
Northwestern buys electricity on the market rather than generating it in its
own dams, regardless of what it pays for the dams? That’s a little like assuming
that no insurance policy is ever worth what you pay for it. And if the Counsel
makes that assumption does it really have the interests of consumers at heart?
Apparently not: When it says that Northwestern can always be held harmless in
the face of rising electricity costs by passing on those rising costs to
consumers, the Counsel seems to be more concerned about insuring Northwestern
than the ratepayers.
* There are a lot of other
aspects of the proposed dam purchase and the proposed price that the PSC needs
to look at of course.
