Announcement
Envision Energy announced on 24 September 2026 in Hamburg, Germany the launch of its next‑generation offshore wind turbine, the EN‑252/16.7, aimed at high‑wind environments and international offshore markets.
Technical Specifications
The EN‑252/16.7 delivers a rated power of 16.7 MW and features a high‑performance rotor with a swept‑area‑to‑power ratio of approximately 2.99 m² per kW. It is built on the Model Z platform, which has been in operation since 2023, and incorporates a Europe‑specific rotor, an integrated powertrain, and vertically integrated key component technologies.
Performance and Economic Benefits
For a gigawatt‑scale offshore wind farm, the turbine is expected to increase annual energy production by roughly 1‑2 % while reducing the number of turbines required by about 10 % relative to currently available models. This reduction translates into an estimated 2‑4 % decrease in levelized cost of energy (LCOE), subject to site conditions and project configuration. Where site conditions permit, the turbine can be uprated to further lower turbine count and capital expenditure (CAPEX).
Reliability and Safety
The turbine has undergone extensive component‑ and system‑level validation, including drivetrain system loading tests and more than 600 hours of highly accelerated life testing for the drivetrain. Envision’s in‑house experience encompasses approximately 12,000 gearboxes, 12,000 main‑bearing sets, 25,000 blade sets, 23,000 generators and 28,000 converters. It is designed to survive a 10‑minute average extreme wind speed of up to 58.5 m/s and a three‑second gust, occurring once in 50 years, of up to 82 m/s. Integration with Envision BESS provides long‑duration backup power for critical turbine devices and safety‑related functions during grid outages, pre‑commissioning, or severe storms. The turbine also features grid‑forming control, black‑start capability, and stable operation under weak‑grid and fault conditions, with autonomous operating capabilities that maintain power to essential systems when conventional grid support is lost.
AI‑Driven Lifecycle Management
The turbine is equipped with Envision’s AI‑powered Galileo monitoring system, which has been commercially applied to more than 20,000 turbines since 2020. Galileo employs over 30 functional models to monitor major components and failure modes, delivering early‑warning reports one to six months in advance depending on the condition. This early fault detection enables more timely maintenance planning, reducing unplanned interventions and lifecycle operating expenditure (OPEX). An AI‑turbine interface allows for future upgrades and the continued evolution of intelligent turbine operations.
Executive Comment
Christian Schrimpf, Executive Vice President of Offshore Wind at Envision Energy, stated that the value of scale lies in translating larger turbines into higher energy production, greater reliability and stronger economics across the project lifecycle, and that the EN‑252/16.7 brings these capabilities together to help customers capture more value from offshore wind over the long term.
