Project
Details
Florida Power and Light (FPL) submitted a Site
Certification Application to the Florida Department of Environmental
Protection (DEP) on June 30, 2009. If
approved, the application would allow FPL to expand nuclear energy
production at its Turkey Point facility in Miami-Dade County.
The proposed project consists of the construction of two new 1,100
megawatts (mW) nuclear units, 6 and 7, and supporting facilities, as well as
the placement of new transmission lines.
The State of Florida would
license both the transmission lines and new electrical power plants in one
proceeding pursuant to the State Power Plant Siting Act (PPSA), Chapter 403,
Part II, Florida Statutes (F.S.).
The two nuclear generating units with supporting buildings, facilities and
equipment are proposed to be located due south of the existing Turkey Point
units, on a parcel currently within the industrial wastewater /cooling canal
system. Associated facilities
proposed in or around the new or existing plant units include parking areas;
a nuclear administration and training building; a reclaimed water treatment
facility and treated reclaimed water delivery pipelines; radial collector
wells and delivery pipelines for cooling water backup; and an equipment
barge unloading area. A new
electrical substation (Clear Sky) will be constructed on the Turkey Point
site. A 230-kV transmission
line also will be needed to connect the new substation to the existing
substation on the plant property.
The application requests transmission corridors within the following
communities: unincorporated Miami-Dade County, Miami, Coral Gables, Doral,
Homestead, Medley, Palmetto Bay, Pinecrest, and South Miami.
A transmission corridor may be up to a 6.5 miles in width to
accommodate reclaimed water pipeline. Within
a corridor, transmission lines and other system improvements may be placed.
The application also requests the creation or expansion of access
roads and bridges (between SW 328 Street and SW 359 Street and east of SW
137 Avenue). The Miami-Dade
County Comprehensive Development Master Plan Amendments for these proposed
access roadway activities were adopted by the County on April 28, 2010.
FPL has indicated that the existing transmission line infrastructure is
insufficient to carry the load that will be generated by the new reactors.
New 500 and 230 kilovolt (kV) electric transmission lines are needed
to connect the proposed Clear Sky and existing Turkey Point substations to
other existing FPL substations in Miami-Dade County.
Because of the load requirements, two separate transmission line
corridors have been proposed, totaling approximately 88.7 miles.
The East Preferred Corridor is a 36.7 mile area proposed by FPL to
connect the existing Turkey Point substation to the new Clear Sky and
existing Davis and Miami substations. The Davis to Miami portion will run through more urbanized
sections of U.S. 1 from Palmetto Bay through Downtown Miami; one 230-kV line
will be constructed along this 17.7 mile section of the corridor.
The West Preferred Corridor will connect the new Clear Sky substation
to the existing Levee substation, with two 500-kV lines; the West Preferred
Corridor will also connect the new Clear Sky substation to the existing
Pennsuco substation, with one 230-kV line.
The Levee to Pennsuco portion will run through Doral and Medley.
The full West Preferred Corridor is 52 miles in length; it is 43.6
miles from Clear Sky to Levee and 8.4 miles from Levee to Pennsuco.
Three transmission lines are proposed to be constructed within a
single right-of-way up to the existing Levee substation.
