Envision Energy announced a major milestone in wind power innovation. Its next-generation two-blade onshore smart turbine prototype has now surpassed 500 days of stable operation, achieving an impressive availability rate of 99.3%, a mean time between trips (MTBT) of 2,444 hours, and equivalent full-load hours of 3,048 annually. Field data shows that the performance of this two-blade turbine is comparable to traditional three-blade models installed at the same site.
The prototype is based on Envision’s Model X onshore platform and incorporates a modular design along with high-speed Doubly-Fed Induction Generator (DFIG) technology to enhance system stability. Engineered for lightweight construction and high system-level efficiency, the turbine offers a cost-effective and scalable energy solution for a variety of green power applications.
Envision’s development of two-blade turbine technology dates back more than a decade. In 2012, its Global Innovation Center in Denmark introduced the “Game Changer,” a 3.6 MW offshore two-blade turbine—making Envision one of the earliest companies to explore this unconventional design within the global wind energy sector. Since the installation of the prototype in 2013, the company has accumulated deep operational and technical experience, which has directly informed the advancement of its latest two-blade platform.
“By overcoming key technical challenges such as excessive system vibration and load imbalance – barriers that have long held back two-blade designs, Envision has once again redefined wind power innovation by becoming the first in the industry to demonstrate long-term operational verification of a next-generation two-blade turbine.” said Mr. Lou Yimin, Senior Vice President and Chief Product Officer at Envision Energy.
