OCAS® – part of the Vestas Group Improving bottom line and enhancing acceptance Our collision detection warning system has many potential benefits for your wind energy project – all of which impact your bottom line as an investor. · Faster approval times: Communities will no longer be subjected to night-long light because the aviation lights are only activated if needed. This may aid a faster permit process, so your wind energy project can be up and running sooner. · New commercial opportunities: Sites with regulatory lighting restrictions may now be open for development as wind energy plants. · Increased ROI: Reduced use of aviation lights enables taller, higher-yielding turbine heights.
