Poseidon Transmission Project To Save Long Island Ratepayers Millions

The Poseidon project will offer ratepayers in Long Island access to affordable and reliable energy.

The proposed 500MW high-voltage direct current (HVDC) Poseidon Project is at the end of the interconnection process with PJM Interconnection (a Regional Transmission Organization in the United States) and the New York ISO (NYISO). The project’s in-service date is scheduled for 2020.

Transmission project achieves technical milestones

Anbaric unit Poseidon Transmission 1 says that the Poseidon Project has achieved two significant technical milestones as part of its interconnection process, including approval by the NYISO Operating Committee of the project’s system reliability impact study (SRIS). The approval confirms that the project successfully complies with the reliability standards of the state’s electric system, and it means that Poseidon has completed the Public Service Law Article VII application requirements. The state Public Service Commission will now begin its review of the project and the formal portion of the Article VII proceeding.

The NYISO determination follows a PJM facilities study report, issued end January, which found that Poseidon will not need any system upgrade to facilitate its interconnection.

“The fact that Poseidon will interconnect seamlessly with both NYISO and PJM demonstrates the project’s superior design,” Clarke Bruno, senior vice president of Poseidon Transmission, “When energized, Poseidon will save Long Island ratepayers tens of millions of dollars per year through expanded access to more affordable and reliable energy resources.”

The project, which will deliver energy to Long Island, N.Y. – NYISO Zone K – from the PJM market, will be completely buried along existing rights of way or underwater, and will not generate air emissions and water discharges.

Transmission projects to help meet clean energy goals

Other projects include the Vermont Green Line, previously known as the Grand Isle Intertie, which will connect upstate New York with New Haven, Vermont. The project is expected to be in service by 2019. The line will unlock 400MW of clean energy resources in upstate areas that are transmission-constrained. This power will be transmitted to the New England states, enabling them to attain the regions’ clean energy goals.

Edward Krapels, CEO and founder of Anbaric Transmission, says that transmission must be built to areas that have ample wind energy. Krapels points to a recently released draft request for proposals (RFP) for clean energy and transmission to deliver clean energy by the Connecticut Department of Energy and Environmental Protection, the Massachusetts Department of Energy Resources and six electric distribution companies of Massachusetts and Rhode Island. Krapels says that this RFP “is just right for our Vermont Green Line project,” and that the company will submit a bid in that process.

Another project that is underway is the 1,000MW Maine Green Line project, which is part of the Green Line Infrastructure Alliance, a collaboration involving Anbaric and National Grid plc subsidiary National Grid USA. Anbaric Transmission is in the middles of permitting the ISO process. The project’s in-service year is 2021.

Krapels noted that the drivers behind the projects differ by region, adding, “Anbaric meticulously designs its projects to find the gap between what the grid is built to do and what policymakers want it to do.”
