OUR PROJECTS

PowerBridge’s flagship projects are the Neptune Regional Transmission System, completed in 2007, and the Hudson Transmission Project, completed in 2013. Both are underwater cable projects that were completed on budget and ahead of schedule. A third underwater cable project, Cascade Renewable Transmission Project, is in development. In addition, PowerBridge selectively pursues other energy and infrastructure projects, such as the TAQA Gen-X Gas Pipeline described below, that are an appropriate fit for our capabilities and expertise.

NEPTUNE

The Neptune Project is a 660-MW (500 kV) high-voltage, direct current (HVDC) submarine electric transmission cable, completed in 2007, that connects power generation resources in the PJM system to electricity consumers on Long Island. The cable extends from the First Energy substation in Sayreville, New Jersey to the Long Island Power Authority Newbridge Road substation in Levittown, Long Island, a distance of 65 miles.

The Neptune Project is a 660-MW (500 kV) high-voltage, direct current (HVDC) submarine electric transmission cable, completed in 2007, that connects power generation resources in the PJM system to electricity consumers on Long Island. The cable extends from the First Energy substation in Sayreville, New Jersey to the Long Island Power Authority Newbridge Road substation in Levittown, Long Island, a distance of 65 miles.

Converter stations are located at Sayreville and at Duffy Avenue on Long Island. The majority of the route – more than 50 miles — is underwater in the New York Harbor and the Atlantic Ocean; 14 miles are buried in the existing right-of-way of the Wantagh State Parkway. The Project was completed in the summer of 2007, ahead of schedule and within budget.

In May 2004, the Long Island Power Authority (LIPA) chose the Neptune cable as the centerpiece of its long-range plan to provide approximately 1000 MW of new, urgently needed power sources to Long Island by 2010. Because the cable is a transmission connection to the PJM system, it increases the capacity and energy available to Long Island in a more flexible and reliable manner than simply siting new generating facilities on Long Island. Moreover, it saves Long Island ratepayers money, adds capacity and makes available more (and diverse sources of) energy without adding local impacts associated with new power generation.

HUDSON

The Hudson Transmission Project is a 660 MW electric transmission link between New York City and PJM Interconnection that was completed in June of 2013. While its main purpose is to provide a new source of electric power for the New York City customers of the New York Power Authority (NYPA), the Project also provides New York City with access to renewable resources throughout PJM and includes very significant upgrades and reinforcements to the transmission system in New Jersey.

The Hudson transmission line is entirely underground and underwater, using HVDC technology. The route begins in Ridgefield, New Jersey, the site of a new converter station, where it interconnects with the PJM system at a PSE&G substation. The line follows existing railroad rights-of-way, through an inactive railroad tunnel to the edge of the Hudson River in Edgewater. It is then buried beneath the Hudson for approximately three miles to a landfall point near Pier 92 in Manhattan. The final half-mile of cable is routed beneath the West Side Highway and ultimately into the ConEd W. 49th Street Substation.

The Hudson Transmission Project was conceived in response to a public solicitation by NYPA in the spring of 2005 by which NYPA requested proposals for the supply of 500 MW of electric power capacity for its customers in New York City. Hudson Transmission Partners, LLC (HTP) responded with its proposal to provide a minimum of 500 MW of firm transmission capacity via an underground-and-underwater link to the PJM system. The proposal was selected by NYPA in 2006. Construction on the project began in May 2011 and was completed in June 2013, ahead of schedule.

CASCADE

Cascade Renewable Transmission is an underwater and underground electric transmission cable proposed for the Pacific Northwest, capable of delivering approximately 1,100 MW of clean, renewable energy from east of the Cascade Mountain Range to electricity consumers west of the Cascades while also helping to meet renewable energy public policy requirements in Oregon and Washington.

Cascade Renewable Transmission is an underwater and underground electric transmission cable proposed for the Pacific Northwest, capable of delivering approximately 1,100 MW of clean, renewable energy from east of the Cascade Mountain Range to electricity consumers west of the Cascades while also helping to meet renewable energy public policy requirements in Oregon and Washington.

Cascade Renewable Transmission starts in The Dalles, Oregon and travels approximately 100 miles west to the Portland area, with interconnection points planned at existing substations. For the most part, the cable will be installed under the Columbia River, taking care not to disturb sensitive river habitats or existing river uses. Between the river and the interconnection points, there will be short stretches of line buried underground. In addition, the cable will exit the river for about 7 miles to bypass the Bonneville Dam on the Washington side of the river. Buried underwater, and underground, Cascade will have no visual impact or disturbance of natural habitat or populated areas.

The Pacific Northwest region -- and particularly Oregon and Washington -- is facing an imminent shortage of electrical capacity needed to serve customers and meet public policy requirements. Cascade Renewable Transmission will form a new pathway to bring wind and solar power from eastern Washington and Oregon, and even Idaho, Montana, and Wyoming, to the load centers west of the Cascades reliably and affordably.

TAQA GEN-X GAS PIPELINE

The TAQA Gen-X Pipeline is a .37 mile natural gas pipeline developed and built by PowerBridge for TAQA Gen-X, LLC, a joint venture between units of Abu Dhabi National Energy Co. and Morgan Stanley. Located in the town of Sayreville, New Jersey, the TAQA Gen-X Pipeline provides fuel from New Jersey Natural Gas (NJNG) to the 832 MW Red Oak generating plant, providing an alternate source of natural gas to the combined cycle electric generating facility.

PowerBridge conducted extensive environmental studies, obtained all major permits and regulatory approvals, and oversaw construction and commissioning of the TAQA Gen-X Pipeline and associated metering station facilities. The TAQA Gen-X Pipeline began commercial operation in December 2014, making Red Oak NJNG’s largest customer.
