New York's demanding energy market
As New York's energy market changes, transitioning to more intermittent energy sources, New York City needs to maintain the reliability of its power supply while reducing potential emissions. The city – with more than 8.5 million inhabitants – is moving to obtain 70 percent of its energy from renewable sources by 2030. When solar and wind power can't meet the need, quick start peaking units like the Gowanus Generating Station will become even more important, especially in congested areas like Southwest Brooklyn. The new units will provide that reliability while reducing emissions and offering the flexibility to move the barges as needed.
The four-barge Gowanus Station, with a current generation capacity of 640 MW, was originally installed in the early 1970s and is approaching the end of its service life. By replacing those barges with two modern floating power barges provided by Siemens, Astoria Generating Company will be able to retire the existing barges, reducing the total number of barges from four to two, and also retire two barges at the nearby Narrows Generating Station. Siemens will deliver eight SGT-A65 gas turbine generating sets – four on each barge – along with a Siemens control system. The turbines will run on natural gas as their primary fuel.
"As a holistic solution, the new SeaFloat power barges will help reduce potential emissions in New York City and provide a reliable power supply by helping keep the local grid stable," said Karim Amin, CEO of Power Generation at Siemens Gas and Power. "SeaFloat combines the advantages of our high-quality proven power plant technology with the mobility and flexibility that's required in peak consumption periods."
Each SGT-A65 (Industrial Trent 60) aeroderivative gas turbine will deliver up to 76 MW for the Astoria project in simple cycle service at 41.8 percent efficiency. With its fast cold-start capability and high cyclic life, these engines can rapidly add power to the grid to compensate for fluctuating and variable renewable and other energy sources, making it an ideal solution for peaking markets. More than 115 of the SGT-A65 gas turbines have been sold worldwide with more than 1.8 million fleet hours of experience.
Siemens and Astoria also signed a contract for a 20-year long-term service agreement that will help support the gas turbines' and generators' optimal operating efficiency. The contract includes service on parts, repairs, field services, program management, and offerings from Siemens' Omnivise Digital Services portfolio, including remote monitoring and diagnostics.
"As New York's energy market changes to rely on intermittent power sources like wind and solar, we need to ensure reliability. These state-of-the-art units will provide the quick-start energy production New Yorkers need while reducing potential emissions. And best of all, because they're on barges, they provide the needed climate adaptation, adjusting to sea-level rise and increased storm surges, and also can be moved if the power is needed elsewhere," said Mark Sudbey, CEO of Astoria Generating Company.

SeaFloat solutions
Variations of the SeaFloat power plants can be used as base
load or emergency
backup for existing power plants during peak loads or outages
and to provide a fast
power supply in the event of a humanitarian disaster.
SeaFloat power plants can
even be supplemented with a desalination plant to provide
clean potable water that helps prevent disease. A wide range of gas turbine
frames and combined cycle
configurations are available so that an appropriate solution
that meets specific
requirements can be developed with customers.
The Siemens SeaFloat power plants use the company's proven
and reliable equipment that's been adapted for application on floating devices.
SeaFloat power plants can be moved to any site that's accessible by sea or
major rivers and require almost no investment for land acquisition. SeaFloat
has been designed to be as small as possible, and it's defined a new standard
in power density. Because the plants' construction and a large portion of commissioning
are performed using standardized equipment under strictly controlled conditions
in the world's leading shipyards, a short lead time can be realized.
Construction of the plant also doesn't interfere with any required onshore
infrastructure like the installation of substations, transmission lines, and
access roads. This allows for a significant reduction in the total time
required for these kinds of infrastructure projects. Typical applications
include the power supply for remote areas like islands, the development of
industrial areas on shorelines or major rivers (for example, chemical and
desalination plants), and brownfield applications.
