Interconnections
In New York, SMRT Line will interconnect with and deliver power to NYISO Zone J at
Con Edison’s Gowanus 345 kV substation. Con Edison has reviewed the proposed
interconnection location and determined it to be feasible. Deepwater’s wholly-owned
subsidiary – New York Wire, LLC – holds NYISO queue position #307 and has
completed an Interconnection Feasibility Study for this location. Deepwater also
executed a NYISO SRIS agreement on August 18, 2010.
This substation was chosen in large part because of recent upgrades that allow it to accept
a new high-voltage interconnection without the need for expensive system upgrades.
Gowanus is also ideally located on the waterfront with a number of sites in the immediate
vicinity where a converter station could be located.
In New Jersey, SMRT Line will interconnect at the JCP&L’s Larrabee 138 kV substation
where Deepwater, through its wholly-owned subsidiary, Big Bight Transco, holds
interconnection queue position V3-026. Deepwater has completed the PJM
Interconnection Feasibility Study and is awaiting the results of the System Impact Study.
Deepwater selected the Larrabee substation as the most appropriate point of
interconnection for several reasons, but primarily because it is located south of the more
congested portion of New Jersey’s electric grid, which means that firming power can be
exported to Zone J more readily (i.e., without substantially increasing congestion in the
area), and more cost effectively.
Alternative Wind Farm Sites
The federal waters off New York City hold the potential of supplying a large quantity of
offshore wind to serve the load pockets of Zones J and K. Deepwater has commissioned
a series of desktop studies that suggest that there are at least two general areas that would
be suitable for offshore wind development. The first, the northern site, is the area that
was identified by the Collaborative and for which NYPA submitted an unsolicited lease
request last December to BOEM. The other site is one that is situated southwest of the
Collaborative site and has similar characteristics.
While some differences exist between these two development areas, including water
depths and the projected wind resource, Deepwater has concluded that the sites are
roughly equivalent from a wind farm development perspective. Therefore, while some
modifications might be required it should be feasible to design the SMRT Line network
to serve either or both development sites, which is why Deepwater has spent several
years investing in these interconnection positions.
