It’s hard to believe that the summer of 2021 is nearing the end. While the past 18 months have been challenging for everyone as we learn to manage life in a pandemic-altered world, it has also been a very exciting time for the stakeholders of Cookson Hills Electric as we continue making progress on our fiber-to-the-home project.




We want to notify our members of a planned outage on our system. The transmission provider that supplies power to Substation 14 (Liberty Substation) will be performing maintenance on Substation 14 during the month of October.
