PJM Electricity Usage Tops 100,000 MW; Sets World Record
"Reaching this milestone emphasizes that large-scale coordinated regional grid operations are practical and effective," said Audrey A. Zibelman, PJM executive vice president and chief operating officer. "Centrally dispatched regional grids provide the economies of scale that underlie the benefits of efficient competitive wholesale electricity markets. Not only is the grid more reliable, but we've also seen a real decrease in prices because of competition."
The PJM system had enough generating capacity and reserves to deliver all the electricity that customers used. Demand on the system tomorrow is expected to be even higher. PJM forecasts that power supplies again will be adequate to handle the expected usage of electricity.
PJM became the world's largest grid operator last year. Since May 2004, the transmission systems of Commonwealth Edison, American Electric Power, Dayton Power and Light Company, Duquesne Light Company and Dominion were integrated into the PJM regional transmission organization. Prior to the integration of the new systems, all-time peak electricity usage in PJM was 63,779 MW. One megawatt is enough electricity to power about 800 homes.

Opinion: With deregulated electricity, no need to subsidize nuclear power
PITTSBURG - For decades, the government regulation of Pennsylvania's electricity markets dictated all aspects of power generation resources in the state, thus restricting market-driven prices for consumers and hindering new power plant development and investment.
Deregulation has enabled competitive markets to drive energy prices downward, which has transformed Pennsylvania from a higher-electricity-cost state to one with prices below the national average.
Recently, the economic advantage of abundant low-cost natural gas has spurred an influx of billions of dollars of private capital investment and thousands of jobs to construct environmentally responsible natural gas power generation facilities throughout the commonwealth — including our three…
