23-2 Water Supply Plan
Invenergy Thermal Development LLC (Invenergy) has not constructed a natural gas/oil fired electric generating facility with the same design features as proposed for CREC as posed by this question. Process water source and demand are unique features of nearly every electric generating facility.
Invenergy has constructed six natural gas fired electric generating facilities and has a seventh under construction. Some, but not all of them, also fire oil. Invenergy’s St. Clair, Ontario, Grays Harbor, WA, Nelson, IL and Lackawanna, PA facilities all have larger water demands than CREC. The water supply for Invenergy’s Cannon Falls, MN, Spindle Hill, CO and Lackawanna, PA facilities are all supplied with water from a public water supply. Invenergy’s facilities in St. Clair, Ontario, Nelson, IL, Grays Harbor, WA and Ector County, TX source their water from either rivers or wells. All of these facilities use a pipeline to deliver water.
The water savings technologies identified under the Water Supply Plan were utilized to minimize consumption and, therefore, allow for the delivery of water by truck. It is Invenergy’s understanding that Ocean State Power (OSP) utilizes trucked water for its wet cooled plant. It is also Invenergy’s understanding that the water plan for the proposed Exelon West Medway LLC generation project in Massachusetts includes trucking water as a back-up source of supply, if needed.
