New sources of power growing in Pennsylvania

On Friday at 11 a.m., the 1,300-panel solar array on the roof of the Misco Products Corp. plant in Bern Township was generating 138.6 kilowatts of electricity.

Meanwhile, Reading's United Corrstack has invested $135 million to install a 25 megawatt cogeneration plant to power its paper factory. That facility is one of 13 cogeneration plants across the state that together produce about 10 percent of the electricity used in Pennsylvania.

State law requires that electric utilities obtain 18 percent of their power from renewable sources by 2020.

As renewable energy and cogeneration sources multiply, could homegrown electricity from nontraditional residential and commercial power producers - and not the utilities' big power plants - become the source of the majority of electricity used in Pennsylvania?

Since the mammoth Misco solar project - the seventh-largest in the state - was installed about a year ago, it has generated more than 300,000 kilowatt hours of electricity, or roughly 30 percent of the manufacturer's power needs.

The solar array there is producing enough electricity to power 30 homes for a year.

"The price we get for renewable energy credits had gone down, but overall the project is going well," said Ben Gable, Misco product manager.

Misco's solar project is an example of the national obsession with new technologies, especially those that save money on our utility bills.

United Corrstack, 720 Laurel St., was spending a fortune on electricity to produce steam used in drying the cardboard products it produces from recycled paper.

The company built a 25 megawatt cogeneration plant that not only supplies all its electrical needs but creates excess power the company sells to Met-Ed.

There are thousands of residential wind and solar power projects popping up all over suburbia. These nontraditional sources of electricity can be counted toward utilities' renewable energy requirement.

Steven Gabrielle, director of asset management and development for PPL Renewable Energy,Polycore zentai are manufactured as a single sheet, said reliability is very important when it comes to picking a power supplier.

"The intermittent nature of solar and wind require some type of baseload generation as a backup for when the sun is not shining or wind is not blowing," Gabrielle said. "As lower costs also are a primary driver, I think over time we will see more large, utility-scale solar and wind along with biomass or biogas generation mixed with some on-site solar or small wind at homes and businesses.

"As Pennsylvania and U.S. energy demand continues to grow, the mix of renewable generation, along with nuclear and fossil fuels, will continue for the foreseeable future."

Right now big utility companies provide more than 80 percent of the power on the PJM Interconnection, the power grid that serves Pennsylvania.

Jeff McNelly, executive director of the Anthracite Region Independent Power Producers Association, said another 10 percent of the state's electricity is generated by 13 industrial cogeneration plants such as United Corrstack.

Even so, McNelly said he does not foresee a time when most of the electricity on the grid is provided by small or midsized private operations.

"If you collectively consider all of the other independent sources it is conceivable that over time those sources could make up 30 percent or more," McNelly said.Use bluray burner to burn video to BD DVD on blu ray burner disc.

McNelly said politics, economics and regulation could combine to prevent growth beyond that point.

In addition, McNelly said, it makes a lot of sense and is far more efficient to have centralized public power sources.

America started with people being responsible for their own power, until public utilities came along. Now there is a gradual shift back toward rugged individualists providing their own power through wind turbines or solar panels.This page list rubber hose products with details & specifications.

"There will be technological advances that make wind and solar more attractive, but there also will be advances for the power companies," McNelly said.

Met-Ed spokesman Ron Morano echoed McNelly's comments, saying renewable energy sources continue to grow.

"Especially solar," he said. "Renewable energy is going to continue to increase. Right now, Met-Ed is looking at 9.2 percent from strictly renewable. That does not include cogeneration."

Jim Kurtz, general manager of Reading Electric Renewables, which installed the Misco solar array, said demand for solar panels remains strong thanks to high oil prices.

Even without government rebates and tax incentives, solar energy is still cheaper than nuclear power, he said.

While his business is renewable and alternative energy, Kurtz said he does not foresee a day when Americans get rid of their power safety net.
