Substation Upgrades

Substations take power from high-voltage transmission lines and lower the voltage level so it can be sent in multiple directions to homes or businesses via smaller distribution lines.

Periodic upgrades to various substations in the MEA service area are necessary to support a safe, reliable system that meets increasing usage demands. Without these upgrades, members are likely to experience more outages. MEA’s substation upgrades also affect the entire 500-mile-long railbelt grid. Since the grid functions as an integrated system among many electric utilities, MEA has a responsibility to provide modern, stable substations.

Listed below are current substation upgrade projects underway:

Herning Substation Upgrade

MEA’s Herning Substation is located at the south end of Denali Street off of East Susitna Avenue in Wasilla and serves much of the commercial and industrial members in the Wasilla area. The Herning Substation Upgrade project will replace equipment in the substation that has reached the end of its useful life and will provide two transmission feeds to the substation to increase reliability.

The project is expected to start in mid-June of 2020 and be completed by summer of 2021. Currently there are no planned outages for local businesses during the substation upgrade project.

Parks Substation Redesign and Updating

The Parks Substation, located on Steffes Street in Birchwood, has reached the end of its useful life. This project will replace existing aging infrastructure to continue to provide safe, reliable service to thousands of residences in the Chugiak-Birchwood area. MEA has been working closely with the community on the Design and Planning process of the substation upgrade project. Changes to the Parks Substation would occur after all permitting has been completed with the Municipality of Anchorage and the community has had the opportunity to provide input. We hope to complete the project permitting process by the end of 2020 and begin construction in 2021.
