The Bureau of Reclamation awarded a $1.85 million contract Sept. 2 to ABB, Inc. in Cary, North Carolina, to replace transformer oil coolers at Grand Coulee Dam.

Over the past several years the existing transformer oil coolers have shown the need for replacement, the bureau said in a press release. The contract will require furnishing and installing new transformer oil coolers, as well as disposal of the existing ones. The work is scheduled to be complete by April 30, 2015.

“This project is just one way Reclamation is continuing to ensure efficient and reliable power production in the Pacific Northwest,” said Grand Coulee Power Manager Coleman Smith. “Replacing these transformer oil coolers will help to provide many more years of reliability at Grand Coulee Dam.”
