Introducing The Cypress Platform
GE Renewable Energy has launched its new onshore wind turbine platform, named Cypress, and the next model from that platform, GE’s 5.3-158 wind turbine.
The platform advances the proven technology of GE’s 2 MW and 3 MW fleets, which serves an installed base of nearly 20 GW, while also utilizing architecture and innovations from the 4.8-158 wind turbine introduced in 2017.
Cypress enables significant Annual Energy Production (AEP) improvements, increased efficiency in serviceability, improved logistics and siting potential, and ultimately more value for customers. It is designed to scale over time, enabling GE to offer a wider array of power ratings and hub heights to meet customer needs throughout the 5 MW range.
The platform also offers up to a 50 percent increase in AEP over the life of the platform versus GE’s 3 MW turbines.
A revolutionary two-piece blade design
The Cypress platform, which also includes the 4.8-158, will be powered by a revolutionary two-piece blade design, enabling blades to be manufactured at even longer lengths and improving logistics to offer more siting options. Longer blades improve AEP and help drive down Levelized Cost of Electricity (LCOE), and the proprietary design will allow these larger turbines to be installed in locations that were previously inaccessible.
It significantly drives down logistical costs, by enabling blade assembly onsite and reducing the costs for permitting equipment and road work required for transporting longer blades. Equally importantly, it features blade tips that offer customers greater flexibility to address site wind conditions and requirements.
The high-tech carbon blades were developed through the longtime partnership between GE’s Onshore Wind business, GE’s Global Research Center and GE’s LM Wind Power, taking advantage of the research, design and large-scale manufacturing expertise of these teams to bring the blades from concept to a tested and proven reality.
The Cypress platform, designed for IEC (S) wind speeds, leverages the best of GE's 2 MW and 3 MW turbines – including the proven DFIG (doubly-fed induction generator) – and a robust drivetrain architecture.
The machine is specifically designed for services, with enhancements to help with facilitating up-tower repairs and troubleshooting with its up-tower electrical system, while also pushing the limits of traditional reliability levels on major components, through increased systems level hardware testing and more robust manufacturing processes.
This combination of planned, condition-based and predictive services will help to ensure more reliability, uptime and production while ultimately lowering lifecycle costs for the customer.
