NYISO Reveals Bids in NYC Offshore Transmission Solicitation
NYISO received four bids in response to its Public Policy Transmission Need solicitation to deliver up to 8 GW of offshore wind power to New York City.

NYISO this month received four bids in response to its Public Policy Transmission Need solicitation to deliver up to 8 GW of offshore wind power to New York City. 

Each developer proposed multiple options, differing by size, number of offshore platforms and HVDC cables, or interconnection points. They are: 

    • energyRE Giga-Projects USA, with three options for its Clean Borough Power Link; 
    • Viridon New York, with three options for its Liberty Link; 
    • New York Transco, with 10 options for its Energy Link New York; and 
    • the New York Power Authority and LS Power, with 12 options for its Five Boro Energy Connect. 

Most project options propose to connect to Consolidated Edison’s Brooklyn Clean Energy Hub, expected to be completed in 2028. But many others propose to interconnect via DC-to-AC converter stations that have not yet been approved. 

NYISO issued its solicitation in response to an order by the New York Public Service Commission in June 2023. The PSC mandated that projects accommodate at least 4,770 MW of offshore wind, with options to expand up to 8 GW. (See New York PSC Calls for More Transmission for Long Island OSW.) 

Viridon and energyRE proposed in-service dates of December 2032 for all of their proposals, while NY Transco proposed January 2033. NYPA and LS Power’s proposed dates vary by option, with the earliest being September 2032 and latest December 2033. 

New York’s Climate Leadership and Community Protection Act calls for 9 GW of offshore wind by 2035. The state’s — as well as the U.S.’ — first utility-scale project, the 130-MW South Fork Wind Farm, began operating in March. The 924-MW Sunrise Wind project received federal approval last week.

“The investment in transmission is needed so that we are prepared for the future state,” said Susan Craig, spokesperson for NYPA. “The expectation is that generation sources will be there to connect.” 

NYISO will conduct a viability and sufficiency analysis on all the proposals that is expected be conclude in the fourth quarter. The Board of Directors will select a proposal in the second quarter of 2025.  

Craig compared the Five Boro project to Propel New York Energy, which included the construction of new underground transmission lines and substations. Developed by NYPA and NY Transco, Propel was selected by NYISO’s solicitation in June 2023 to meet the PSC’s order for projects to connect up to 3 GW to Long Island.

“New transmission is essential for the reliable deployment of offshore wind, and energyRe is ready to modernize New York’s electric grid in support of the state’s clean energy goals,” company COO Ryan Brown said in a statement. 

“As New York develops more renewables, we will need the necessary transmission to carry that clean energy to homes. Energy Link NY is the best project for the job,” said Will Hazelip, vice chair of NY Transco’s board and president of National Grid Ventures. 

“LS Power’s joint proposals with NYPA will deliver state-of-the-art transmission solutions that provide New York City with more renewable generation to integrate into the electric grid and increased reliability to meet power demand, while also minimizing environmental impacts,” LS Power CEO Paul Segal said.
