Posted on: Friday, 31 March 2006, 15:00 CST

CHICAGO, March 31 /PRNewswire-FirstCall/ — Exelon Generation Company, LLC and Peoples Energy today announced they have agreed to accelerate Exelon’s purchase of Peoples’ 30 percent interest of the Southeast Chicago Energy Project for $50 million, subject to certain closing adjustments.

Southeast Chicago Energy Project is a 350-megawatt natural gas-fired, peaking electric power plant located on Chicago’s southeast side. It began operation as a joint venture between Exelon Generation and Peoples Calumet, LLC in the summer of 2002 with Exelon controlling 100 percent of the output of the facility.

Since the facility came on-line, Exelon has owned and controlled the output of the facility, while Peoples supplied fuel to the plant. Exelon will continue to own and control 100 percent of the plant’s output and Peoples Energy will remain as fuel supplier to the plant.

The purchase by Exelon is subject to Federal Energy Regulatory Commission (FERC) approval. This purchase does not affect Exelon’s market position within the PJM Interconnection because under the original agreement with Peoples Energy, Exelon Generation controlled 100 percent of output from the facility.

Exelon Corporation is one of the nation’s largest electric utilities with approximately 5.2 million customers and more than $15 billion in annual revenues. The company has one of the industry’s largest portfolios of electricity generation capacity, with a nationwide reach and strong positions in the Midwest and Mid-Atlantic. Exelon distributes electricity to approximately 5.2 million customers in northern Illinois and Pennsylvania and gas to more than 470,000 customers in the Philadelphia area. Exelon is headquartered in Chicago and trades on the NYSE under the ticker EXC.

Exelon Generation’s fossil generation portfolio consists of a number of intermediate and peaking stations, located in southeastern Pennsylvania, Massachusetts, Illinois, and Texas.

The Exelon Generation fossil portfolio consists of approximately 6,500 megawatts of capacity produced using coal, oil, and natural gas. The diverse fuel mix allows the company to remain competitive in the deregulated utility market by ensuring power during intermediate shoulder seasons and peak demand times when prices for energy are high.

Exelon’s peak generation facilities provide more than 2,000 megawatts of supplementary power for use during periods of high demand.

 

Southeast Chicago Energy Project  is a 352-megawatt (MW) generating facility located in the southeast section of Chicago, Ill. 

The eight-unit facility provides much needed peak generation to the city of Chicago during periods of high electric demand in the summer and winter months.  Each unit at Southeast Chicago is rated at 44 MW and runs on natural gas.

One of the first new gas-fired facilities sited within the city of Chicago, it was hailed as one of the cleanest, most modern, and efficient generating stations in the United States.

Southeast Chicago Energy Project was built as a joint effort between Exelon and PERC Power Generation, a unit of Peoples Energy Corporation and was completed in 2002.  Exelon has since become 100 percent owned of the plant.

Southeast Chicago Energy Project is a Level-1 Blackstart facility.  In the event of a major power system failure, Southeast Chicago Energy Project will be used to re-energize the electric system and bring other regional power plants back online.

 

This facility is located on 96th street off of the Chicago Skyway (according to google maps)

 

Cromby Generating Station is two unit generating station located on the Schuylkill River in Phoenixville, Pa.

Cromby Unit 1 and Unit 2 were installed in 1954 and 1955, respectively.  Unit 1 is a 144-megawatt (MW) coal fired unit that is one of Exelon’s most utilized units with more than 330,000 hours of service.  Unit 2 is a 201 MW unit that operates on either natural gas or No. 6 fuel based on fuel markets.

The emergency diesel generator supplies power during episodic emergencies, such as safe emergency shutdown of the plant or periods associated with high system demands, which occur during extended hot weather conditions.  Under these conditions, the emergency generator is put on-line to run plant auxiliaries, which in turn frees up more capacity from the main units for the regional electric grid.  The 3 MW unit operates on No 2 oil.

Eddystone Generating Station is a four unit generating facility located on the Delaware River in Eddystone, Pa. 

Construction of the plant began in the mid-1950s with Unit 1 and Unit 2 coming on-line in 1960 and Unit 3 and Unit 4 coming on-line in 1974 and 1976, respectively. 

Unit 1 and Unit 2, each 294 megawatts (MW), are nearly identical supercritical steam boiler-turbine generator units that operate on coal. 

Unit 3 and Unit 4, each 380 MW), are identical subcritical steam boiler-turbine generator units that run on either natural gas or No. 6 oil based on market pricing.

Eddystone Generating Station also has four combustion turbines, which supply power during peak demand periods.  Units 10 and 20 and 30 and 40 are identical pairs of units that were installed in 1967 and 1970, respectively.  Each 15 MW combustion turbine operates on No. 2 fuel oil.

Schuylkill Generating Station is a one-unit, 166-megawatt (MW) peak generation facility located on the banks of the Schuylkill River in Philadelphia, Pa.  The facility operates during periods of increased demand on the regional power grid.

The central steam plant portion of the station was sold, in 1996, to an independent power producer (Trigen).  The remaining Exelon portion consists of one main unit and two combustion turbines.

The two, 15-MW, Combustion Turbines, operated on No. 2 fuel oil and are used to meet summer and winter regional peak demands.

Exelon’s Distributed Generation fleet consists of numerous combustion turbine (CT) assets, located throughout Southeastern Pa.  With a total capacity of 1,078 megawatts, these units provide remote site start capability and are used for peak demand periods and load balancing.

Exelon operates 35 natural gas and oil fired CT units at 10 sites in Bucks, Chester, Delaware, Montgomery and Philadelphia Counties in Pennsylvania.

Three units also provide synchronous condenser turbine operation for system reliability and voltage stability.

These small units, sometimes referred to as “jets,” are used for peak demand generation during the hottest and coldest days of the year.

New Boston Generating Station is a two-unit 355-megawatt station located in South Boston, Massachusetts.

Unit 1 runs on natural gas.  The site also houses a 20-megawatt, Pratt & Whitney gas turbine, peaking unit.  The unit operates on distillate fuel oil. 

Unit 1 was built in 1965 as an oil-fired plant.  Today, Unit 1 utilizes natural gas, and continues to provide reliable service to the Boston area.

Unit 2, also an intermediate unit, was damaged in a fire in 2003.  Unit 2 remains offline.

Framingham Generating Station is a three-unit, 41-megawatt station located in Framingham, Massachusetts.

The units at Framingham are used to provide much needed power and voltage support during peak energy periods.

The three units at Framingham Generating Station have been instrumental over the last few years by providing voltage support in the Framingham area.

The units at Framingham can be operated locally, or remotely.  Units can be “black started,” or re-started without outside power, within minutes from complete shutdown.

West Medway Generating Station is a three-unit, 173-megawatt (MW) station located in West Medway, Massachusetts.
West Medway’s Rolls Royce Avon engines were the first of 12 dual-fuel engines installed in the world.
The three peaking were installed by Boston Edison following the 1965 East Coast blackout.  The units were classified as “black start” (able to start up without outside power) for steam generating stations and to provide power to the local electric grid during times of peak demand.
Exelon purchased West Medway Generating Station in 2002.

 

Handley Generating Station is a five-unit 1,441-megawatt (MW) station located in Fort Worth, Texas.

The station provides power to customer in the Electric Reliability Counsel of Texas (ERCOT), when needed.  In May 2003, an SCR (Selective Catalytic Reduction) system was installed to reduce Nitrogen Oxide (NOx) emissions on units 4 and 5.  A similar project was completed on unit 3 in 2004 – reducing NOx emission by more than 90 percent.

Site generation dates back to 1902, when the Northern Texas Traction Company built a generating plant, the largest in the area, along the adjacent Lake Erie.  Now known as Lake Arlington, the lake serves as a popular recreation and amusement area for the local community.

When Unit 1 was built, it was the first outdoor steam electric generating station of its type in the industry.

Mountain Creek Generating Station is a five-unit, 893-megawatt (MW) station located in Dallas, Texas.

The station provides power to customer in the Electric Reliability Counsel of Texas (ERCOT), when needed.  In May 2003, an SCR (Selective Catalytic Reduction) system was completed on Unit 8.  The system reduced Nitrogen Oxide (NOx) emission by 90 percent compared to 2002 levels.

The site’s original 34.5 megawatt, air-cooled generator, now retired, was built in 1938.  Its first hydrogen-cooled, natural gas, 33-megawatt unit was built in 1945.  When Unit 8 was added, it was only the second super-critical unit in the United States.

ExTex LaPorte Generating Station is a four-unit, 160-megawatt (MW) station located in Houston, Texas.

The station provides power to customers in the Houston regions during peak demand situations.  The four combustion turbines on the site, part of Exelon’s peaking fleet, are maintained by Airco Industries.

ExTex LaPorte Generating Station was Exelon’s first wholly-owned power plant in Texas.
