In the effort to reach 100% adoption of LED street lights throughout the city, Anchorage experienced impediments due to asset ownership across four agencies. The City investigated collaborative pathways to implement the city-wide retrofit project.
Municipally-owned and utility-owned street lighting.
The City of Anchorage, AK realized an annual energy savings of $260,000 after converting about 4,000 street lights to LED technology. The city determined LED street lights an acceptable option in support of sustainability initiatives and began pursuing ways for broad scale deployment by converting the balance of its inventory. The inventory assessment revealed street light ownership by the State Department of Transportation, Municipal Light & Power (ML&P), Municipality of Anchorage, and Chugach Electric. The city’s Maintenance and Operations Department is responsbile for installations per the outcome of the Anchorage Assembly’s authorization of a $1.6 million contract to install LED street lights with the ability to add controls and network the system with other agencies in the future. The added controls will enable Anchorage to manage inventory outages and replacement in a street lighting system with multiple owners.
