KIUC works to keep birds off power lines

LIHU‘E— The Kaua‘i Island Utility Cooperative is resuming the set up of chicken diverters on energy traces to scale back collisions with endangered nocturnal seabirds.

The diverters connect to line spans — the horizontal distance between two helps, corresponding to wooden poles or metal towers. Utilizing drones, the cooperative put in diverters on 109 spans in 2020, and expects to put in diverters on an extra 628 spans by the tip of 2021.

The cooperative is utilizing two sorts of equipment.

“Reflective diverters are small gadgets that glow at nighttime and assist Newell’s shearwater, Hawaiian petrel and band-rumped storm petrel keep away from energy traces as they fly mauka to makai after darkish,” KIUC Transmission and Distribution Supervisor John Cox mentioned in a press launch.

“LED diverters use a small photo voltaic panel that expenses through the day and produces mild that’s seen to birds all through the night.”

KIUC’s islandwide challenge is prioritized primarily based on bird-collision ranges and line accessibility, KIUC spokesperson Beth Tokioka instructed The Backyard Island in an e-mail.

“Lots of the installations will happen in distant areas that gained’t be seen to residents,” she mentioned. “For any installations close to residences, we’re contacting these members immediately by mail previous to the scheduled work.”

KIUC makes use of LED diverters, that are passive with no digital output, in distant areas of Kaua‘i. The reflective selection is utilized on spans nearer to residential areas, industrial districts and public roadways.

Engineering and Know-how Supervisor Cameron Kruse has said KIUC set up crews will reduce disruption to visitors whereas the work is going down.

Chicken diverters are estimated to be 40% to 90% efficient in minimizing power-line collisions, relying on sort and site, in line with Tokioka, who famous information remains to be being collected.

The cooperative can be working with U.S. Fish and Wildlife and the state Division of Forestry and Wildlife, funding applications and research devoted to understanding at-risk chicken species and performing line reconfigurations along with diverter installations, in line with Tokioka, who mentioned KIUC is the key monetary sponsor of the Save Our Shearwaters program on Kaua‘i.
