The benefits to be gained from emergent solid state lighting and adaptive control technologies promise to be substantial over the coming decade. Light emitting diodes (LEDs) are gaining in popularity, especially for outdoor streetlights, primarily because of their vastly improved efficiencies and potential for long service life. Compared to the legacy streetlights of today, those benefits could translate into new value for outdoor streetlights owned by utilities.

Utilities face four primary challenges with respect to SSL streetlights and adaptive control technologies. These include 1) the large number of vendors and products; 2) frequent product obsolescence; 3) higher initial costs; and 4) uncertain performance reliability. Municipal stakeholders also have different, and sometimes competing, objectives to be realized from the technology.

A body of knowledge, experiences and insights is developed as utilities begin to address the challenges by formulating solutions, discussing them internally and trying out new rate designs.

This research project examined rate design practices from several early adopter utilities and identified important issues around new standards specific to solid state lighting and adaptive control technologies. Recommendations have been developed using collaborative input from many stakeholders and aligned with utility and municipal interests to reflect just and reasonable rates that will support the business of streetlights using market transformation technology.
