Mass CEC releases shadow flicker study results

By Kathryn Gallerani | Wicked Local Kingston | Posted Jun 11, 2013 | www.wickedlocal.com

The shadow flicker study for the five wind turbines operating in Kingston was released to the town Monday night.

The study was conducted using computer modeling combined with on-the-ground verification of line-of-sight from public streets.

The flicker model identified 808 receptors – or a house measuring at lease 20 meters wide and 10 meters in height – theoretically affected by shadow flicker without accounting for tree cover, neighboring buildings and other obstacles.

Of these 808, according to the results, 188 are expected to realistically receive greater than 10 flicker hours per year and 54 are expected to realistically receive greater than 30 flicker hours per year.

To reduce shadow flicker to no more than 10 and 30 hours per year at any residential structure, each turbine would have to be curtailed a minimum of six hours and a maximum of 336 hours per year.
