Siemens Gamesa has launched its newest high-capacity factor turbine for the US market at ACP CLEANPOWER conference.
The SG 4.4-164 model is the result of continuous development built on Siemens Gamesa’s experience with proven wind turbine models, the turbine manufacturer said.
The model leverages both established and updated platform design to minimize costs and streamline construction, and is available for projects reaching commercial operation in 2025, it added.
The SG 4.4-164 will utilise the capabilities of Siemens Gamesa’s blade facility in Fort Madison, Iowa, and nacelle assembly facility in Hutchinson, Kansas.
The turbine’s 81-metre blades were designed by Siemens Gamesa’s design team in Boulder, Colorado.
Siemens Games chief executive for onshore North America, Shannon Sturgil said: “With a country as large as the US, we took into account the unique challenges of onshore wind sites from coast to coast, including transportation and logistics, varied wind conditions and environments, state-by-state noise, electrical, and power delivery requirements, and the applicable IRA incentives.
“This is truly an onshore wind turbine designed for America.”
