Utilities Thrilled, Worried About Electric Cars

By Jonathan Fahey, AP Energy Writer

NEW YORK (AP) — The first mass-market electric cars go on sale next month, and the nation's electric utilities couldn't be more thrilled — or worried.

Plugged into a socket, an electric car can draw as much power as a small house. The surge in demand could knock out power to a home, or even a neighborhood. That has utilities in parts of California, Texas and North Carolina scrambling to upgrade transformers and other equipment in neighborhoods where the Nissan Leaf and Chevrolet Volt are expected to be in high demand.

Not since air conditioning spread across the country in the 1950s and 1960s has the power industry faced such a growth opportunity. Last year, Americans spent $325 billion on gasoline, and utilities would love even a small piece of that market.

The main obstacles to wide-scale use of electric cars are high cost and limited range, at least until a network of charging stations is built. But utility executives fret that difficulties keeping the lights on for the first crop of buyers_and their neighbors_could slow the growth of this new niche.

"You never get a second chance to make a first impression," says Mike Rowand, who is in charge of electric vehicle planning at Duke Energy.

Auto executives say it's inevitable that utilities will experience some difficulties early on. "We are all going to be a lot smarter two years from now," says Mark Perry, director of product planning for Nissan North America.

Electric cars run on big batteries that are charged by plugging into a standard wall socket or a more powerful charging station.  A combined 30,000 Nissan Leafs and Chevrolet Volts are expected to be sold over the next year. Over the next two years, Ford, Toyota and every other major automaker also plan to offer electric cars.

Governments are promoting the expensive technology as a way to reduce dependence on foreign oil, cut greenhouse gas emissions and improve air quality. Congress is offering electric car buyers a $7,500 tax credit and some states and cities provide additional subsidies that can total $8,000. The Leaf sells for $33,000 and the Volt sells for $41,000.
