The projects detailed on this page represent just a few examples of our ongoing and planned system improvements. Click on a project’s title to read more about it. If you have questions or comments, contact us via the form on our Contact page.

Bayou-Elizabeth Transmission Rebuild

A rebuild of approximately 9 miles of 115-kilovolt transmission line between our Bayou Substation in Douglas County and Elizabeth Substation in Elbert County is complete. The new line was energized in March 2022.

Deer Creek Canyon

The upgrade of 2.5 miles of existing three-phase distribution line with a larger conductor will increase capacity and improve reliability. Construction was completed in March 2022.

Downtown Castle Rock

Installation of a larger conductor on 1.1 miles of existing three-phase distribution line will increase capacity and improve reliability. We anticipate construction will be completed in Spring 2022.

Elizabeth Substation Rebuild

CORE plans to rebuild this substation to increase capacity and improve reliability.

Franktown Substation

A new substation near the intersection of Highways 86 and 83 on the north side of Franktown will accommodate load growth in that area. We expect the substation to be in service in Spring 2022.

Harris Park Rebuild

Construction will begin in Spring 2022 to upgrade 3 miles of existing single-phase distribution line and remove open-wire secondary line.

Palmer Lake Rebuild

CORE is upgrading approximately 9 miles of single- and three-phase distribution lines and member line taps to improve reliability, improve aesthetics, and bring facilities and equipment up to CORE’s latest standards. Phase 1 of the three-phase project is complete. Phase 2 will begin in Summer 2022, and Phase 3 in early 2023. Click here for additional information.

West Platte River Road

A reroute of 5 miles of single-phase distribution and rebuild of secondary line along West Platte River Road, east of Foxton in south Jefferson County, will eliminate river crossings, improve access and increase reliability. The mountainous terrain necessitates the use of helicopters to remove and set wood poles. Construction on this project is expected to be completed in Spring 2022.

Wildfire Mitigation Plan

CORE is committed to mitigating the risk of wildfire to protect our members, employees and distribution system. We have implemented a comprehensive wildfire mitigation plan to reduce the risk of CORE’s equipment and facilities causing a wildfire. The plan is intended to safeguard members, our employees and the electric system upon which you rely now more than ever. More information about the plan is available here.

Woodland Park-Divide Rebuild

A rebuild of approximately 7 miles of existing three-phase line along Highway 24 between Woodland Park and Divide is complete and in final cleanup. The new line was built with fiberglass arms and polymer insulators that will better withstand the magnesium chloride used to de-ice the highway.
