A joint venture of the New York Power Authority (NYPA) and New York State Electric & Gas (NYSEG) have completed a $120m transmission project that will connect more upstate renewable energy to more populated downstate areas.
The Marcy South Series Compensation project is expected to provide up to 440MW of additional transmission capacity, and help relieve congestion, or bottlenecks, that affect the ability to deliver surplus upstate electricity.
The project involved the installation of three capacitor banks – two by NYPA and one by NYSEG – that offer greater control of power movement.
The capacitors will enable operators to have more awareness of transmission conditions so power can be dispatched more effectively to areas where it’s needed most, the NYPA and NYSEG said.
The project, which started in late 2015, also involved replacing about 22 miles of conductors and upgrading some structures on NYSEG’s portion of the Marcy South transmission line.
NYSEG plans to transfer its $61m portion of the Marcy South project – NYPA spent $59m – to New York Transco, a public-private partnership of investor-owned utilities in New York, at a future date.
