Utilities like Duquesne Light Co. have three jobs. They generate
electricity, usually by heating water to create steam to turn giant turbines. Any fuel
will do, but Duquesne relies primarily on coal-fired boilers and nuclear power plants.
Once a stream of electricity is created, it is carried by high-voltage
cables on huge steel towers from the power plant to the areas where the power is needed.
When the power arrives, a gentle trickle of the juice is sent down the
wires that criss-cross streets and neighborhoods and feed into our homes and factories.
Pennsylvania is introducing competition into the generation stage of the
business. Transmission and distribution will remain regulated monopolies. Few people, for
instance, would want a competing electric company coming down their street to string yet
another set of wires.
In the future, utilities like Duquesne Light will act somewhat like the
Postal Service delivering to its customers whatever they choose to buy from
whomever they chose to buy it. Just as your postal carrier will deliver your winter coat
whether you ordered it from the Sears catalog, Spiegel or L.L. Bean, so too will your
utility deliver the electricity no matter whom you buy it from.
But who will sell it to you, and how will they get it to Western
Pennsylvania?
Some outside companies may purchase Duquesne Light's power plants at
Beaver Valley, Elrama, Cheswick and elsewhere when the utility sells them next year under
orders from the Public Utility Commission. These suppliers would then market their power
to whomever wants to buy it.
Others might produce power miles or even states away to sell to
Pittsburgh customers. Here is how that works.
Adjacent utilities generally work together to pool their power, swapping
electricity back and forth to make sure everybody has enough at any given time.
Imagine it as a huge lake. The lake level will remain stable when you
take out your water as long as someone, somewhere, is dumping in a corresponding amount of
water. That's why a company can produce power in Indiana, for instance, to serve customers
in Pittsburgh. The Pittsburgh customer pulls it out of the pool and the Indiana power
plant dumps more in.
That works, however, only if there are enough high-voltage transmission
wires in the right place to make sure power can flow freely between utilities to keep the
system stable. And that is what had the PUC so concerned about the proposed Duquesne Light
Co.-Allegheny Energy Inc. merger. Together, the two companies would have controlled so
many transmission routes it could have limited competition in this region, the PUC feared.
Richard Zomnir and Alexander Galatic of Strategic Energy Ltd., an energy
management firm, compare the wires to high-speed toll roads. How easy it is to get on
those roads and how expensive they are to travel will help determine whether customers
will save any money through electric competition.
Think of it this way. If an auto dealership in Philadelphia were selling
cars for thousands less than dealers in Pittsburgh, people could save a bundle by buying
over there, even with the additional travel costs. But if there were no easy way to get
the car back home or if the turnpike was so expensive that it sucked up all the
savings the faraway dealer would not provide any real competition in the Pittsburgh
market.
To prevent that from happening, the PUC set stringent restrictions on
the proposed Duquesne Light merger. The new company would have had to turn over operation
of its transmission lines to an independent alliance, so competitors would be assured of
getting access to the Pittsburgh market. If that was unworkable, the company would have
had to sell off some of its generating plants to ensure that outside competitors had power
to sell to Pittsburgh-area customers.
Sound a little obscure? But those were among the restrictions that
caused DQE Inc., Duquesne Light's parent company, to scuttle the merger. Duquesne Light
decided to go it alone and get out of the generation business all together.
