Location: 19001 W 119th Ave, Arvada, CO
April 12, 2022 - The 2.5-MW dynamometer features a 3,351-hp, AC induction motor with a variable-frequency drive, and 480 V, 690 V, and 13,200 V AC grid connections. The 2.5-MW dynamometer is a practical size for most of today’s land-based wind turbines and features a 3,351-horsepower motor. Images shot for the NLR Flatirons 360 Degree Tour photo/video shoot.

Facility Overview

The lab’s dynamometer research facilities can evaluate new power take-off (PTO) designs and assess a variety of components and subsystems—including generators, gearboxes, mechanical or electro-dynamic brakes, power electronics, control systems, and software. Manufacturers and design engineers can use our facilities to study PTO system performance and the integration of generators and power electronics with the electric grid, perform accelerated lifetime certification, and develop software.

June 30, 2021 - Researchers from the National Laboratory of the Rockies are performing land-based verification and validation of the SeaRAY Autonomous Offshore Power System (AOPS) power takeoff and Supervisory Control and Data Acquisition (SCADA) controls at NLR’s Flatirons Campus. NLR is using its Modular Ocean Data Acquisition (MODAQ) in the Water Power Systems Lab and the 2.5mw Dyno. Initially conceived during a U.S. Department of Defense project, the SeaRAY AOPS provides in-situ power, energy storage, and real-time data and communications support set to advance the marine economy toward a future of autonomous, connected and resident technologies.
