Flathead Electric Cooperative’s Scheduled Tree Maintenance

System Trim

Flathead Electric Co-op is committed to providing safe, reliable energy, which necessitates trimming trees near power lines. Our tree trimming is not random, but by design, and strives to be proactive as opposed to reactive. Trimming is guided by our Vegetation Management Program, which recognizes:

  1. Trees are the cause of the majority of our power outages.
  2. Trees are also a very important part of the natural beauty of our valley.

This program is based on industry best practices designed to prevent dangerous situations and ensure electric reliability.

System Trim Program

Trees growing near and into power lines can create public safety hazards, start fires and cause power outages. In your Co-op’s service territory, trees are pruned or removed on a rotating schedule. Flathead Electric Cooperative’s entire power system is on a ten-year trimming cycle, approximately. To protect the 2,116 miles of overhead line, crews have a big job to do, trimming trees along 150 to 200 miles of line each year. This is in addition to responding to hundreds of tree trimming or removal requests from our members each year.

We understand that our members value trees – as does their Co-op! These same members, however, also rely on their Co-op to provide reliable power – in good weather and in bad. That’s why our tree care experts work to find a balance between reliable power and healthy trees. We are committed to working collaboratively with you to address any concerns before tree work begins.
