During the course of this study, a number of ongoing and future pilot and demonstration projects came to light in addition to the eight described above. Some useful material on each project is listed below; the information draws largely from press releases and MSSLC discussion notes and is not based on project manager surveys. This list of current

demonstrations and pilots is merely a sampling of the projects and installations identified during research.

PG&E: ALADDIN AND VIRTICUS

PG&E is currently testing the Aladdin controls system in San Francisco, California at its Beale Street headquarters. The project manager for this pilot noted that the installation maturity was not sufficient to provide useful data or inform substantive conclusions. PG&E also plans to test the Virticus system, as well, at the same location.

CALIFORNIA LIGHTING TECHNOLOGY CENTER: LUMEWAVE

California Lighting Technology Center (CLTC) is a University of California, Davis affiliated group focused on lighting energy efficiency and technology development. CLTC has received a grant from the California Energy Commission (CEC) to develop basic network adaptive control standards that cities could use as a template for purchasing such systems. CLTC is

The Center is also partnering with Lumewave to test its streetlight controls system. CLTC has installed the Lumewave controls system on six 70W bi-level induction roadway fixtures on the UC Davis Campus. Each fixture is installed with an occupancy sensor which can determine the occupant‟s direction of travel. This pilot project was funded by the California Energy

Commission‟s Public Interest Energy Research Program.42

THE CITY OF SEATTLE, WA: OWLET

The city of Seattle has been studying LED technology in streetlight applications since 2008. It installed 5,000 residential LED fixtures in 2010 and is also currently planning a small pilot project, potentially involving the Owlet controls system.

Seattle‟s concerns about data security drive its interest in a controls solution that offers self- hosting capabilities so that data can be stored behind city and utility firewalls. Additionally, the city wanted fixtures with controls pre-wired and commissioned prior to installation. The city also noted the importance of flexibility in a controls device‟s installation options to allow it to be fitted on varying pole and fixture types. As of May 2011, the city reported that

implementation of this project had yet to begin.

THE CITY OF HAVERHILL, MA: CIMCON

The city of Haverhill, MA announced in February 2011 that CIMCON had been selected to implement a three-month wireless streetlight management pilot program using the

LightingGale controls system. CIMCON controllers will replace photocell sensors on about 50 of the city‟s streetlights. The purpose of this project is to reduce energy and maintenance costs of its streetlight system while maintaining resident safety.43

THE CITY OF AUSTIN, TX: ROAM

In August 2010, the Austin City Council approved the installation of a comprehensive streetlight management system. The purpose of this installation was to precisely and

proactively identify system outages, improve repair and response time and save energy. During the first phase of this project, 3,300 fixtures will be fitted with ROAM controls by the end of summer 2011.

In February 2011, Acuity Brands announced that the city of Austin will be controlling all 70,000 of its fixtures with the ROAM controls system. This system will be installed and

operated by Austin Energy, with an anticipated completion date of 2014. The ROAM system will save an estimated $1,000,000 annually in combined energy and maintenance costs.44

ONCOR: ROAM AND TYCO

Oncor is a regulated Texas electrical utility serving about one-third of the state and operating about 400,000 streetlights. Oncor started a project in December 2008, installing 548 luminaires with the TYCO Lumawise system. Due to the frequency of severe electrical storms in the area, Oncor replaced all nodes in July 2010 to increase their ability to withstand lightning strikes. Oncor installed three gateways (although only two were required) to provide redundancy to guard against communications failures.

Oncor reported that the TYCO system was extremely sensitive; faults indicated in the TYCO system would often clear without intervention after a day. Oncor therefore had little confidence in the reliability and accuracy of TYCO‟s fault monitoring capabilities. The utility also reported contractors and maintenance personnel unaware of the TYCO system physically removing the TYCO controllers when they did not recognize them. Oncor purchased the system for one year, specifying a single administrator able to grant access to 30 people. Oncor appreciated the ability to provide unique IDs and passwords, with individualized access and permissions. In a separate LED pilot project beginning in September 2010, Oncor also tested the ROAM monitoring system on 506 lights in a variety of settings and applications. Oncor expressed satisfaction with ROAM‟s ability to diagnose problems within the network. Oncor has a two- year contract agreement with ROAM and pays on-going service fees. Oncor noted that the utility would have preferred to host and control its own data, rather than to have to rely on a third party for this service as is currently required.

THE CITY OF PUEBLO, CO AND BLACK HILLS ENERGY: AIRINET

Black Hills Energy, in partnership with the city of Pueblo, Colorado, is engaged in an LED Street Lighting Initiative45 to evaluate LED technology for use in street lighting applications. Black Hills Energy installed 10 new 250W equivalent LED lights and 10 new 250W HPS lights in June 2010, which it will monitor for two years using the Airinet system. Airinet controllers are currently tracking temperature, energy consumption and burn hours.46
