Meeting Philadelphia's Future Heat and Power Needs: The Grays Ferry Cogeneration Project

Kevin E. Brown, Vice President of Marketing and Development, Trigen-Philadelphia Energy Corp.; Herman A. Schopman, P.E., Vice President of Operations, Trigen-Philadelphia Energy Corp.

The Grays Ferry area of Philadelphia, Penn., is the site of a $170 million cogeneration project currently being developed by Trigen-Philadelphia Energy Corp. and its partners. When construction is completed later this year, the dual-fueled, combined-cycle plant will produce 150 MW of electric power and 1.4 million lb/hr of steam. In addition to helping Philadelphia meet its energy needs, the project is also expected to have a positive impact on the city's ambient air quality.

A Profile in Persistence: Wisconsin Electric Purchases Total Energy Center

John Hyland, Project Manager, Business Development, Wisconsin Electric Power Co.

In the early 1990s, the 40-year-old Milwaukee County Power Plant needed significant improvements even as county officials were under pressure to decrease spending. Wisconsin Electric Power Co. determined that acquisition of the 110,000-sq-ft plant, which produces district heating, cooling and cogenerated electricity, would help the company meet its long-term goals. After three years of stop-and-start negotiations, the company's persistence has paid off: Today it owns a 'total energy center' that not only helps position the company for the future but also affords its customers many benefits.

Calculating the Impact of District Energy in Greenhouse-Gas Reduction

Michael Wiggin, Technology Manager of Community Energy Systems, Natural Resources Canada

How does your company quantify district energy's ability to reduce greenhouse gases? Deciding it needed a better tool for making this type of assessment, the Community Energy Systems group of Natural Resources Canada developed a method of calculating and comparing the carbon dioxide production of various heating technologies. Though based on assumptions for Ottawa, Ontario, this method can be adapted for use in other district energy markets.

District Energy and Cogeneration: Questions and Answers on the European Marketplace

When IDEA's 1997 annual conference convenes in June, the focus will be on the global district energy industry. In preparation for this meeting, District Energy interviewed three leaders in European district heating, cooling and cogeneration for their comments on the state of the industry in that marketplace. Featuring Michael Brown, director of COGEN Europe; David Lawrence, incoming president of EUROHEAT & POWER, unichal; and Henry Manczyk, director of facilities management for Monroe County, N.Y., and consultant on Polish energy issues.
