Program Description

The TIB, a state-funded grant agency, has coordinated with a number of its large investor owned utility (IOU) companies to relight small and low tax base cities in their respective service areas. This program started in summer 2015 and will affect about 80 cities. Grants became available to other cities outside the initial targete service areas beginning in 2016. The program has an estimated cost of $28 million over the targeted ten year timeframe.

Service Area

Small and low tax base cities across the state of Washington.

Situation Highlights

The current trend towards upgrading older street lighting technology with LED appears to be less available to smaller communities, despite the fact that they are among those who would benefit most from the additional savings generated. TIB convinced the state government to establish this program to ensure smaller communities are not left behind in the state’s ongoing transition of its public lighting.

In 2016 discussions were underway with at least 8 Public Utility Districts who expressed interest in the program, following an announcement issued by the Bonneville Power Association regarding the availability of the TIB funding. 

All municipally-owned (vs. utility-owned) lighting systems are in the process of being converted or are completed already. The original implementation schedule was designed to take place over a ten-year timeline but it is likely that 75% will be completed at the five-year mark.

A number of contractors across the state were hired (and hired additional staff) to carry out the conversions. Public responses to the new lights were overwhelmingly positive. Most energy savings averaged between 50-66%.
