Envision’s Two-Blade Wind Turbine Prototype Surpasses 500 Days of Stable Operation

Operational data over 500 days validates the design’s potential to reduce wind farm capital costs.

Explore how Envision’s prototype tamed vibration and imbalance to achieve 99.3% uptime with only two blades—an explainer on the key design innovations.
Envision Energy's two-blade wind turbine achieves 500 days of stable operation.

Overview

  • Prototype reached over 500 days of uninterrupted operation with a 99.3% availability rate, 2,444 hours mean time between failures and 3,048 equivalent full-load hours per year.
  • Field tests confirm the two-blade turbine matches output of three-blade machines at the same onshore site, meeting conventional performance benchmarks.
  • Envision’s Model X onshore platform uses a modular nacelle design and high-speed doubly-fed induction generator technology to overcome vibration and load-imbalance challenges.
  • Validation encompassed months of laboratory testing, nearly two years of field operation at a smart wind power verification center and multi-degree-of-freedom full-system loading rig trials.
  • Lighter construction and modular deployment promise lower material and transport costs that could speed wind farm builds in remote or infrastructure-limited regions.
