Vista-class cruise ships ms Westerdam and ms Oosterdam have been retrofitted to use shore power at the Port of Seattle to reduce both fuel consumption and emissions. The first Oosterdam "plug-in" date was July 29, followed by the Westerdam on July 30. The Holland America Line ships will buy and use electricity (shore power) provided by Seattle City Light, instead of diesel fuel, for power while docked in Seattle. The total cost to retrofit is nearly $1 million per ship. In addition, about $1.5 million has been spent dockside to establish hook-ups and install a transformer. Other than a $25,000 grant from the Environmental Protection Agency and the Puget Sound Clean Air Agency, Holland America Line has assumed all of these costs.
