classical equipment and pioneering ge
solid-state control equipment in 1964.
In fact, a very similar flywheel motorgenerator set installation was used for a
merchant blooming mill
at the Bethlehem steel
plant in Pennsylvania.
However, motor-generator sets were also used
(rather than rotary converters) in some locations
for the more mundane
task of simply supplying
250-V dc power for general usage around
the plant.
I was also interested in Mr. Mertz's
comments regarding the rapid reversing
("plugging") of the rolling mill motors.
around 1970, while I was employed
at the ge High Voltage Laboratory, I was
sent to the then-new Bethlehem steel
plant in Burns Harbor, Indiana, to install

a transient voltage recorder on the power
system for a rolling mill. there had been
some equipment failures that seemed to
be the result of high-voltage surges.
I was in a basement
underneath the rolling
mill, along with a Bethlehem engineer and an
electrician, to install the
transient recorder. suddenly, a thunderously
loud sound occurred,
which was accompanied
by an actual shaking of the building. I
recovered from the shock of that event and
asked my companions something along
the lines of "What in the **** was that?"
they chuckled at my nervousness and
explained that it was nothing to worry
about because "they just reversed the
roll stand."
-Thomas J. Blalock

Suddenly, a

loud sound

Price and Quality
of Electricity After
Deregulation
electricity deregulation is supposed to
bring price reductions to consumers.
However, simple economic reasoning indicates that the price and profits
will tend to increase and the quality
of electricity will tend to decline after
deregulation.
Let us first discuss how prices
change in deregulated marketplaces.
there are plenty of substitutes for
ordinary goods such as food or clothing. For example, if beef becomes too
high priced, one may substitute pork
or chicken for beef. However, there is
virtually no substitute for electricity.
Let us consider elevators. any highrise building is equipped with an emergency staircase. But such a staircase is
not the substitute for an elevator. It is
