The Cook Nuclear Plant
Nuclear Plant is located on 650 acres along Lake Michigan's
eastern shoreline. The tract is part of the world's largest
formation of freshwater dunes. The plant is owned and operated
The construction permit for the plant was granted by the Atomic
Energy Commission in 1969. It was one of the largest construction
projects ever in the state of Michigan with over 2,000 workers
at the site. The plant was named for the late Donald C. Cook,
a Michigan native, and former chairman of the board of American
Electric Power. Unit 1 began commercial operation in August
of 1975, and Unit 2 in July of 1978. Construction cost for
both units was 1.3 billion dollars.
Both units are pressurized water reactors. The 1,048 net megawatt (MW) Unit 1 and 1,107 net MW Unit 2 combined produce enough electricity for more than one and one half million average homes. The
American Electric Power Service Corporation served as architect
and engineer for the project. The nuclear steam supply system
for both units were designed and built by Westinghouse Corporation.
The turbine generators for Unit 1 and Unit 2 were purchased
from General Electric Company and Brown Boveri Corporation
AEP's nuclear generation group is headquartered in Buchanan,
Michigan. The building, located twenty miles from the plant,
also houses some of the nuclear plant's emergency plan facilities.
Approximately 900 AEP employees work at the plant, and 100
AEP employees work at the Buchanan office.
American Electric Power is one of the largest electric utilities in the United States, delivering electricity to more than 5 million customers in 11 states. AEP ranks among the nationís largest generators of electricity, owning nearly 38,000 megawatts of generating capacity in the U.S. AEP also owns the nationís largest electricity transmission system, a nearly 39,000-mile network that includes more 765 kilovolt extra-high voltage transmission lines than all other U.S. transmission systems combined. AEPís transmission system directly or indirectly serves about 10 percent of the electricity demand in the Eastern Interconnection, the interconnected transmission system that covers 38 eastern and central U.S. states and eastern Canada, and approximately 11 percent of the electricity demand in ERCOT, the transmission system that covers much of Texas. AEPís utility units operate as AEP Ohio, AEP Texas, Appalachian Power (in Virginia and West Virginia), AEP Appalachian Power (in Tennessee), Indiana Michigan Power, Kentucky Power, Public Service Company of Oklahoma, and Southwestern Electric Power Company (in Arkansas, Louisiana and east Texas). AEPís headquarters are in Columbus, Ohio.
