Stamford Advocate

While the public's attention has been focused on the rising prices at the gas pumps, one Stamford industry expert said consumers soon should expect a high-voltage shock when they open their electricity bills.

The spike in natural gas and coal prices, which account for more than two-thirds of the fuel used for electric power generation in the United States, could lead to some painful electricity rate hikes this summer, according to Addison Armstrong, director of market research for Tradition Energy, an energy management adviser and procurement firm that has its U.S. headquarters in Stamford.

"Electricity, much like gasoline, is a refined product," Armstrong said. "And all of the inputs used to generate electricity, with the exception of wind, have gotten really expensive."

The expected decrease in imports of liquefied natural gas, coal shortages in Europe and China and low levels of natural gas in storage are all putting pressure on prices, Armstrong said.

In states with deregulated markets, prices could spike as much as 41 percent this summer when consumption is at its peak, Armstrong said.
