Heat Wave Again Puts
Heavy Strain On Power Grid

04:46 p.m Jul 23, 1999 Eastern

SAN FRANCISCO (Reuters) -
Withering heat returned to the
Midwestern United States Friday,
once again forcing power companies
to issue dire warnings that they were
on the brink of running out of
electricity.

This was the second time this month
-- and the summer is only half over
-- that parts of the country's
electrical system have been
overwhelmed by hot weather,
prompting serious questions about
the reliability of service for this
essential commodity.

''In general, it's tight throughout the
region in terms of (power)
transmission and generation,'' said
Steve Brash, a spokesman for
Cincinnati-based Cinergy Corp.

Cinergy, which serves some 1.4
million electric customers, was one of
several big Midwestern utilities
issuing appeals Friday for customers
to cut back on electricity use or face
possible blackouts.

Indianapolis Power & Light Co.,
with its biggest power plant down for
emergency repairs, called the
situation a ''critical shortage'' and
raised the specter of rolling blackouts
if voluntary conservation failed to
ease the load on its system.

All this was reminiscent of the rolling
blackouts that plagued parts of New
Jersey and mandatory voltage
reductions from Maryland to Maine
after the stiflingly hot July 4 holiday
weekend.

To cope with high demand, several
suppliers throughout the Ohio Valley,
including Columbus, Ohio-based
American Electric Power Co. (AEP)
and FirstEnergy Corp. in Akron,
Ohio, were forced to cut power to
''interruptible'' industrial customers.

Interruptible customers typically buy
electricity at lower rates, knowing
they can be cut off on short notice if
there is not enough power to go
around.

For some of them, it was the second
time they had been cut off this month,
a move economists predicted could
cost steel mills and other heavy
manufacturing industries in the region
millions of dollars in lost production.

But the bid to shed industrial demand
was seen having the desired effect,
and grid operators predicted they
could squeak through the peak
afternoon hours without cutting
power to commercial or residential
customers.

Though sweltering heat is forecast to
last several days, loads on the system
will most likely dip over the
weekend, when most offices are shut
and air conditioning demand drops.

But the outlook for early next week
is not good.

''We can't see any significant break
in the weather through next
Wednesday,'' said Cinergy's Brash,
adding that the heat and humidity will
spread to much of the East Coast,
leaving that much less surplus
electricity available in the spot
market.

''Right now, we're finding it's
impossible to buy (spot) power for
more than an hour at a time,'' he said.

Hourly prices for electricity delivered
into the Cinergy system hit $3,100
per megawatt-hour Friday afternoon,
an astronomical price compared with
the $25 to $30 range for next-day
delivery into the same system just 10
days ago.
