ice throw analysis
GHD Limited (GHD) was retained by Pattern Energy Group (Pattern Energy) to conduct an ice throw study as part of
the environmental assessment (EA) registration for the wind power project being developed in Newfoundland and
Labrador (NL), Canada, as part of the Argentia Renewables Project (Project). The Project is a green energy project
using wind generated electricity by a 300 Mega Watt (MW) wind farm to power an electrolysis process that extracts
hydrogen from water. The hydrogen will in turn be converted into ammonia for more efficient storage and
transportation by marine vessels to international markets.
The Project will consist of 46 wind turbines located around the Port of Argentia, NL. The ice throw assessment was
completed using the Vestas V172-7.2 wind turbine model, with a hub height of 166 meters (m), rotor diameter of 172
m, and rated power of 7.2 MW.
The risk of ice fall or throw is a notable hazard for wind turbine operations in cold climates. Although there have been
limited ice throw events leading to public property damage globally, and no known recorded events to date of a person
being struck by a falling or thrown ice fragment, the consequences associated can be significant – potentially leading
to serious injury or fatality – and therefore should be mitigated as reasonably achievable. Each incident or accident
caused by ice throw is an unnecessary event and will decrease the public acceptance of wind energy.
The ice throw study presented herein is based on the high-level, conservative approach recommended by the
Canadian Renewable Energy Association (CanREA) in the 2020 Best Practices for Wind Farm Icing and Cold Climate
Health and Safety document [1]. This methodology is widely accepted as being conservative, as ice throw risk outside
of the determined zone is considered null.
Following the methodology described in section 3, with a rotor diameter of 172 m and hub height of 166 m, the
maximum ice throw distance for the planned wind turbines is 507 m.
In Appendix A, this maximum ice throw distance is assessed at each of the 46 wind turbines using Google Earth to
identify hazards within the ice throw zone. Risks identified and potential mitigation measures are detailed in section
5.2 of this report and summarized in section 6 with conclusions and recommendations.
This report is subject to, and must be read in conjunction with, the limitations set out in section 1 and the assumptions
and qualifications contained throughout the Report.
