A number of digital simulations featured on the exhibition floor at AWEA Windpower 2015, with headsets to demonstrate crane operation and blade platforms among others. US turbine manufacturer GE's stand featured an operator seat and three screens to demonstrated its new "Digital Wind Farm" design tool.
GE's program uses holograms to simulate developments to aid design and make maintenance easier. The company said it can help boost production from a project by 20% compared to its existing offering.
US energy secretary Ernest Moniz delivered a speech on day one of the confernece. He is only the second in the role to attend AWEA's conference.
Moniz told delegates of the need to expand wind's footprint in America - to areas where it is not yet cost-effective - using "near-term pay-offs" such as higher hub heights, longer blades, improved drive-trains and better siting.
Siemens Wind Power unveiled the SWT 2.3-120 turbine, which it says extends the reach of its successful G2 turbine platform with a notable 10% increase in annual energy production. It is designed for the US market.
Attendance on the final morning of the conference was nearly 6,500, according to preliminary data from the AWEA, down from an estimated 10,000 registrants over four days in 2014. Exhibitors numbered about 400, down from last year's 440.
