Using natural gas combined cycle technology, NSP will boost output from the two units by more than 100 megawatts. A megawatt of power serves approximately 1,000 homes. The project reflects NSP's interest in providing reliable, economical electricity now and in the future. The existing turbine, generator and other plant equipment will be reused in the new unit. The new system will be housed within the existing building.
Natural gas is used as a fuel to spin a turbine which in turn runs a generator to make electricity.
The system recovers heat from the exhaust gas of the combustion turbine, and makes steam to spin a steam turbine and second electric generator. Integrating combustion turbine and steam turbine technology provides an extremely efficient production process. NSP also will work with the City of Burnsville, the U.S. Fish and Wildlife Service, and the Minnesota Department of Natural Resources. NSP Black Dog project receives local support to top of page Construction schedule With all regulatory and agency approvals anticipated by the fall of 2000, construction should begin during the first quarter of 2001 and be completed by the summer of 2002. Equipment not used in the repowering will be removed prior to construction.
