Description
Replacing all 13.2 kV transformers on the north side of City to 22.8 kV dual voltage transformers and decommissioning the Harbor Road Substation to turn it into a switching yard for the new transformers. This will eliminate maintenance at the current Harbor Road Substation and make the system more efficient in electricity distribution.
Cost
Estimated total cost is $1,387,000. Work is being completed by the City and is expected to come in under budget.
Progress
Planning for this project is already underway. It will extend the Chapman 1 and Chapman 2 circuits north of Harbor Road, improving capacity and reliability for current and future customers north of Governors Creek.
Thanks to funding from a DEO Grant, materials for the project have arrived and are currently being installed. Materials have arrived and the installation is in process. The remaining work involves a few commercial customers whose service will require a temporary outage. We are actively coordinating with those customers to schedule a mutually convenient time for the switchover. Wire installation along Harbor Rd. will begin soon.
Northend of City:
- June: Crews installed nearly 10,000 feet of new wire on poles set and framed to support the upgraded system. As part of this work, 20 new high-voltage transformers were installed, replacing 20 outdated units. All customers in this section were successfully transitioned to the new system.
- July: The project advanced with the conversion of additional customers along County Road 209. Crews set new poles with upgraded materials, installed five new transformers, and retired five lower-voltage units. With this work, all customers previously served by the older infrastructure were fully transitioned.
- August: Crews completed conversions for several customers along CR-209 and installed nine additional poles to prepare for extending the upgrade to side roads once the new feeder wire is in place. These improvements are designed to reduce outage times as we move into the next cutover phase.
- September: City crews removed more than 13,500 feet of overhead cable and are now working with the final customer to complete the switch to the new voltage system. Once that transition is finished, crews will continue removing the remaining wire down to Harbor Road. In September, our contract tree-trimming crews cleared the path for new electrical lines. This work prepares the area for setting new poles and pulling new wire along County Road 209—from Mahama Bluff Road to where Governor’s Creek crosses CR 209.
- October: US17 from Harbor Road to CR 315 - City crews have removed more than 13,500 feet of overhead cable and completed the final voltage transfer for the last customer. They’re now finishing the removal of the remaining wire all the way down to Harbor Road. Northend of City - Crews have started setting poles and installing line along State Road 209 in preparation for pulling new wire for the feeder line. This new section will run from Mahama Bluff Road to where Governor’s Creek crosses CR 209.
- November: Crews completed the installation of new feeder wire along State Road 209 from Mahama Bluff Road to Blackmon Street and converted all homes along this corridor to the new 23kV voltage. Work is now underway to set new poles for the side streets off SR 209 where feeder wire has already been installed. Once those side roads are converted, crews will continue the project further south along SR 209.
