Hundreds of
thousands from Maine to Michigan were plunged into darkness as the result of
the late December ice storm.
People
shivered in the dark. Running generators
in enclosed spaces, some died or became seriously ill from breathing carbon monoxide.
With all the focus
on modernizing the electric system in recent years, you might have thought that
storm-caused outages, especially during the winter, would have been drastically
reduced.
But, while
the country has been concerned about creating competition among generators,
promoting renewable sources and upgrading the transmission grid, government and
regulators have paid little attention to the lines bringing power to homes and
businesses.
In short, the
big picture has been about improving economics and the environment and has
overlooked the more basic public health and safety issues of local poles and
wires.
The emphasis
has been on creating competition in the electric business. Government no longer
regulates who gets into the business of generating electricity.
The only
generation receiving government backing is renewable power, which is supposed
to produce a better environment and less reliance on fossil fuels, especially
imports from politically sensitive places like the Middle East or Venezuela.
The electric
grid has to remain reliable when generators are added, so new federally mandated
agencies have sweeping authority to require new transmission lines. Nobody seems overly concerned about the
billions in added costs rolled into customers’ rates.
All of this
may help meet long-term goals that will make the U.S. more energy independent
and, as the world’s largest power consumer, more efficient and less destructive
of the environment.
But what help
is there for the customer who loses electricity when lines come down under the
weight of ice or tree branches?
The
prevailing attitude seems to be if you choose to live where there are exposed
power lines, you must accept the risk of power outages.
Not only do
ice storms cause massive cuts in service, but many other storms each year leave
electric customers without service for hours or days.
Very little
has changed in the distribution system, the poles and wires that bring power
from the grid to the customer, from the time of Thomas Edison.
Today, just
as more than a century ago, most power outside of cities is delivered on uninsulated,
bare wires at the top of utility poles.
If a tree falls onto a line, that frail and sometimes old wire is broken,
interrupting power until a crew can reach the break and repair it.
Almost no
utility now budgets enough for repairing all breaks in its lines quickly. People, especially those near the end of the
line, must wait, sometimes for several days.
The more remote you are, the later your line is repaired.
Regulatory
supervision over distribution lines is a state matter. Usually state regulators try to get utilities
to keep up with their tree trimming so branches will not contact the bare
lines, but they do little more.
The most
frequently suggested remedy is to put the lines underground, eliminating storm-caused
outages.
The most
obvious problem with this solution is its cost, as much as ten times more than
stringing lines from poles.
In fact, if
we decided we truly want to drastically reduce storm-caused losses of power, it
will inevitably cost more.
But it is
worth at least asking the question if taxpayers or ratepayers are willing to
pay more or shift utility spending from transmission to local distribution systems
rather than simply assuming they don’t.
In the midst
of all the spending on the latest ideas to improve the industry, utilities, the
states or even the federal government might allocates some money spent on high
voltage wires to investigating how to improve the delivery of electricity.
While the
results of such a study cannot be predicted, some ideas might be worth
considering.
How about “distributed
generation,” where small generators could be placed closer to relatively
isolated groups of customers? Perhaps
such generators could be reserved only for emergency use.
Today some
people buy their own generators, but many people cannot afford that investment.
Should there be utility-owned small generators, capable of serving groups of
customers on outlying roads?
What about
increased use of insulated lines, perhaps supported by cable? This so-called “tree wire” would be much less
vulnerable than today’s lines.
And, in some locations,
underground lines should be required to be part of a comprehensive reliability
upgrade to the distribution system.
Maybe none of
these is the right idea. The right idea
would certainly be to begin looking for something better than today’s storm-tossed
distribution system.
