Streetlights, strategic but expensive assets for a city The streetlight network is a strategic asset for a city. Streetlights illuminate the roads we drive on, the pedestrian paths we walk along and the public areas where we gather. It provides us with safe roads, inviting public areas, and enhanced security in our homes, businesses, and city centers. Streetlight networks are also strategic as a potential peer-to-peer network that could be leveraged as a city communication network that could be operated or subcontracted, at a later stage, for environmental data metering, internet communications and distribution of city information and advertising.

But the number of streetlights in a city and their wide geographic distribution make them difficult and expensive to operate: lamp replacements every four years, manpower and service trucks for onsite maintenance operations, increasing cost of electricity and outdated luminaires to retrofit. Street lighting systems add to carbon dioxide (CO², the principal “greenhouse gas”) emissions or nuclear dust from the production of electricity required to power the system. Light pollution also has a negative affect on the environment, impacting plants, animals and people’s sleeping habits.

Did you know that the 90 million streetlights installed in Europe are consuming a total estimated 450 TWH representing an estimated cost of 45 billion US$ per year to cities and being responsible for 180 million tons of CO² each year ?

Once streetlights are inventoried and lamps wattage are optimized not to deliver too much lumens on the ground, cities can apply the European directives in order to save another 40% on energy consumption and on maintenance costs. In summary, these recommendations consist in:

• Replacing traditional magnetic ballasts by electronic dimmable and communicating ballasts

• Dim the lamps in the middle of the night to reduce energy consumption when less light is required

• Automatically identify lamp failures to reduce onsite operations and maintenance costs and to increase citizen’s safety and security by delivering enhanced lighting service.

Streetlight.Vision provides a solution to cities and streetlight maintenance companies, to implement all of these recommendations and benefit from significant energy and maintenance savings within a fast Return-On-Investment (ROI).

Why cities are adopting monitored streetlight systems?

The increased pressure for sustainable development, green and eco cities, reducing maintenance budgets and increasing safety and security for citizens are now pushing cities to find solutions to reduce their spending on streetlight networks while continuously improving light efficiency and safety. The increasing price of electricity is, by itself, responsible for the majority of the increase in streetlight operation budgets. It is now becoming strategic and compelling for cities to implement solutions to identify streetlight failures as well as to measure, analyze and reduce electricity consumption, in order to reduce energy spending, decrease maintenance costs, challenge their electricity providers and contribute to the reduction of CO² emissions, as required by the Kyoto Protocol and local governmental initiatives.


Streetlight.Vision, energy and maintenance saving system Streetlight.Vision is a software and consulting company, specialized in monitoring, control and command software for wide network of streetlight and any other electronic device installed in a city: traffic lights, pollution sensors, advertising screens, decoration lighting, parking, cameras, etc… The Streetlight.Vision solution aims at providing cities and streetlight maintenance companies with energy and maintenance savings as well as lighting service quality and security enhancements. To reach these goals while being robust and open to evolution, the solution is composed of the following four hardware, software and telecom components:

Streetlight.Vision designs and markets a ONE-STOP-SHOP solution that is composed of:

1. Electronic dimmable ballast and its communication nodes (installed in each streetlight) that are the most robust electronic ballast on the market. Their communication node is based on standardized technologies and protocol and enables lamp dimming, failure identification and data metering. Streetlight.Vision markets the electronic dimmable ballast and communication node from SELC (Ireland).

2. Streetlight Segment Controller (installed in each feeder pillar) that are certified by Streetlight.Vision to be compatible with the certified communication nodes and to provide the expected services including astronomical clock (switch ON/OFF at dawn/dusk), scheduler to dim the lamp during the night, local datalogging, data communication over open TCP/IP networks and remote control through the Streetlight.Vision web portal. Certified streetlight segment controllers are manufactured by third party partner companies and resold by Streetlight.Vision.

3. The Streetlight.Vision system supports any type of TCP/IP telecom networks (GPRS, ADSL, Wimax, Wifi, BPL) provided by your local telecom operator which can provide various level of services and security.

4. The central Streetlight.Vision Monitoring Software is designed and marketed by Streetlight.Vision. Its role is to aggregate and filter data from hundred thousands of streetlights through thousands of streetlight segment controllers and transform them into meaningful business information, delivered to streetlight operators through the Streetlight.Vision Web Portal and to third party applications through the open software interfaces (web services, sql, RSS data flow).

3. Secured telecom network

Streetlight.Vision is a Central Streetlight Monitoring System (also called CMS or CSMS)

It enables the remote configuration of your streetlight network (including daily operations and dimming schedules), the analysis, the monitoring and the remote control of the whole streetlight network from a central service center, through a secured web connection.


Streetlight.Vision, to save up to 40% energy and associated CO² emissions

The SELC electronic dimmable ballast/node can dim the existing lamp installed in the streetlight. The streetlight maintenance operator can now configure and optimize its dimming strategy per

streetlight or per cabinet. Most of the streetlights and most of the lamps (e.g. high-pressure sodium) can be dimmed down to 60% between midnight and 4am. The impact of reduced lighting has been studied by streetlight experts through audits and is now recommended by energy saving agency throughout Europe.

SELC electronic dimmable ballasts are lower consumers of electricity (3 watts in average compared to the 15 watts for conventional magnetic ballasts) and are not consuming (almost) any reactive power compared to the average 30% of reactive power consumed by a conventional magnetic ballast.

A city of 1 million inhabitants could save up to 3 millions euros on its electricity budget per year by installing the Streetlight.Vision solution together with electronic dimmable ballasts. As one KWH of electricity

produces an average of 400 grams of CO² (at production), the Streetlight.Vision solution contributes to save tons of CO² by reducing electricity consumption.

For information, the Streetlight.Vision solution also monitors and controls power regulators and variators which are installed in (or close to) the supply cabinet. Such power regulators and variators can dim the whole

energy that is delivered on the electricity supply network. Streetlight.Vision has certified two power regulators and variators that can be controlled. Contact Streetlight.Vision for more information on this matter.

Streetlight.Vision, to drastically reduce maintenance costs

The Streetlight.Vision system identifies and displays all the failures from the lamp, the ballast and the streetlight segment controller right on the desk of the streetlight maintenance contractor. It automatically collects, aggregates, analyzes, lists and sorts streetlight failures and enables to handle alarms to be remotely warned. Cities and streetlight maintenance companies can now reassign maintenance crews at night to added-value tasks and remotely handle any technical problem and operation, thus reducing costs of onsite operations.

Streetlight.Vision, to enhance lighting service and security/safety

By automatically identifying ballast, controller and lamp failures, streetlight downtime are now reduced to one or two days maximum instead of up to several weeks in the past.

Streetlight.Vision, control from anywhere at anytime for any device

Thanks to the Streetlight.Vision solution, any authorized end-user (maintenance operators as well as majors) gets meaningful information to fit his own need: from very technical historical data per streetlight to high level business indicators to estimate energy savings and reduction of CO² emission.

Streetlight.Vision’s solution is based on an open and standardized protocol (named EIA709 in Europe, also called LonWorks), thanks to which it controls and monitors any compatible communicating node and electronic ballast. Streetlight.Vision recommends the electronic dimmable ballasts/node from SELC (Ireland) for its robustness and rich set of features. Thousands of other electronic devices and sensors are compatible with this protocol that can produce data (pollution, air quality, humidity, traffic, advertising and information boards, etc) which can be aggregated, analyzed and displayed in the Streetlight.Vision Web Portal. The Streetlight.Vision solution aims at becoming the Data and Monitoring Center of the City.


Streetlight.Vision, technical architecture The architecture of the Streetlight.Vision solution is summarized on the scheme below:


Streetlight.Vision solution: electronic ballast and communicating nodes

The SELC electronic dimmable ballast can be fully remotely controlled by the Streetlight.Vision software. The Streetlight.Vision software enables to: • Remotely configure and commission the nodes on the powerline network • Switch on and off the lamp remotely • Dim the lamp to any level that is supported by the lamp • Automatically identify failures • Get detailed data (voltage, lamp feedback, …) to troubleshoot any failure • Get the number of running hours as calculated by the SELC electronic dimmable ballast to

anticipate lamp change before they fail • Get the energy consumption from the SELC electronic ballast to calculate and display the

aggregated energy consumption for a whole geographic zone or a city.

Streetlight.Vision’s certified “Streetlight Segment Controller”

In all projects, the certified Streetlight Segment Controller is the iLON100 (designed by ECHELON, USA), that is specially configured and distributed by Streetlight.Vision. One Streetlight Segment Controller is installed in each supply cabinet and can support up to 150 streetlights. The same Streetlight Segment Controller supports Lonworks compatible nodes as well as power regulators/variators. Its role is to: • Switch ON and OFF the lamps using its internal

astronomical clock or using an external photocell. For the UK market, one of the certified node (together with its electronic ballast) can also be switched at dusk and dawn using a photocell on the streetlight.

• Dim the lamps using its internal schedulers. Schedulers can be configured through the Streetlight.Vision software to dim a group of lamps at a certain time in the night. The real time clock of the Streetlight Segment Controller sends commands to the selected nodes at the given time to perform the commands.

• Datalog all data measured by the ballasts/nodes, including lamp failures, lamp level feedback (can be used for energy billing and service quality), energy consumption, running hours, voltage and current, etc…

• Send all recorded data to the Streetlight.Vision M2M Data Collect module through through standard and widely adopted networks such as GPRS, ADSL, WiFi, WiMAX or BPL (Broadband Over Powerline).

• Enable remote control (switch and dimming) of each group of streetlight, of each individual streetlight and of external input/outputs devices located in the cabinet.

Refer to appendix 2 for more technical information.

SELC electronic ballasts perfectly fits with the Streetlight.Vision software

From a technical point of view, SELC electronic ballasts are proven to be amongst the most robust and feature-rich on the market. They exploit open communication protocol to fit with the city open tender processes. They are fully supported by the Streetlight.Vision software to provide a short return-on-investment to end-client.


Streetlight.Vision, the Central Streetlight Monitoring Software

Streetlight.Vision is the first open centralized and online Streetlight Management and Monitoring software Platform. It is designed to be independent from the hardware components (ballasts, nodes and streetlight segment controllers) to enable cities and streetlight maintenance companies to get the best hardware components at the best prices. Nevertheless, Streetlight.Vision recommends the SELC electronic ballast/node/filter.

The Streetlight.Vision Monitoring Software is composed of three complementary components running on a single standard central PC:

• Streetlight.Vision Design and Admin – To be used at design and configuration time

This web-based software module enables administrators to fully configure streetlight segment controllers, commission ballasts/nodes, group streetlights, configure schedulers and astronomical clock, position the streetlights on maps to ease daily operations and create/modify users and user groups. This software module is delivered on the flash disk of the web-enabled streetlight segment controller (for offline usage) as well as in the Streetlight.Vision full package (for online usage).

• Streetlight.Vision M2M Data Collect – Middleware software, transparent for end-users

This software module is installed on a centralized PC server and collects datalogs from thousands of streetlight segment controllers. It filters, aggregates and stores those data as meaningful information in a central open SQL database. Unlike most of the telemonitoring software, the Streetlight.Vision software collects data in a transparent and automatic manner, without any manual action from an operator. It identifies data collect failures and generates alarms when appropriate.

• Streetlight.Vision Web Portal – End-user interface for streetlight maintenance operators

The Streetlight.Vision Web Portal provides with 7 web business applications to authorized end-users, of which streetlight failure identification and troubleshooting, energy efficiency analysis, lamp preventive maintenance, remote control for special operations, lamp dimming configuration, business indicator and geomap data display. These applications have been designed with end-users and streetlight maintenance companies to be intuitive and operational. Screenshots are provided in appendix 1. Online demonstration is available on request to [email protected].

The Streetlight.Vision software can easily be branded for your own city or to be resold as a solution by your company. The Streetlight.Vision solution can also be resold as an online service by Application Service Providers who would sell monthly subscription to this online “Streetlight Service Center”. Several of our reselling partners including SPIE and ABB are already engaged in such a recurrent business strategy. The Streetlight.Vision Web Portal is also designed to provide meaningful information (failures, energy consumption in a timeframe) to existing third party applications such as billing energy applications, work order management tools and GIS.

Streetlight.Vision, selected in most of the large projects in Europe

The Streetlight.Vision solution is awarded GREENLIGHT solution by the European Union (sponsored by the « European Intelligent Energy » program). Each client and partner of Streetlight.Vision can benefit from this label by installing our solutions.


Streetlight.Vision, customer case study The Streetlight.Vision solution has been adopted by large streetlight maintenance companies and cities in Austria, Canada, France, Germany, Ireland, Norway, Spain and the UK. The solution is not only designed for large cities, the benefits apply to all cities of all sizes:

• Large cities such as Oslo (Norway) have reduced the overall costs associated with their streetlight network by almost 50%. (Refer to Echelon’s press release for more information: http://www.echelon.com/company/press/oslolights.htm)

• Smaller cities whose streetlights are monitored by large streetlight maintenance companies can also benefit. As the Streetlight.Vision solution is based on a Web portal, it can handle multiple cities within the same central database and server. Members from each city can access and display its own information related to its own streetlight network.

Background and challenge

The customer case study below describes one of the projects installed in a 16.000 habitants city, a tourist resort with the most beautiful beaches in Brittany, the western part of France. International commitments to tackling climate change, rising energy prices and European directives on energy efficiency have moved the city to consider measures to reduce energy consumption. The city was also very concerned about the efficient use of its citizen’s taxes and about security. In 2005, the city had two main challenges:

1. Reduce energy consumption to contain electricity costs while attaining a 20% reduction of CO² emissions.

2. Reduce the number of lamp failures and lamp down time to avoid potential security issues for drivers and inhabitants.

Solution

SPIE, one of the largest streetlight maintenance companies in Europe, proposed the Streetlight.Vision solution.

Before deploying the solution to the city’s 120 supply cabinets and 3100 streetlights, the city and SPIE first decided to install the solution in a smaller pilot site comprised of one cabinet and 44 streetlights to measure the benefits of the solution during 12 months. The Streetlight.Vision solution was installed in November 2005.

The solution is comprised of:

1. Each luminaire is equipped with a 70W, 100W or a 150W electronic dimmable ballasts from SELC (Ireland) provided by Streetlight.Vision. They communicate utilizing a LONWORKS node that is certified by Streetlight.Vision and installed in the luminaire, as a complement of the ballast.

2. Each supply cabinet is equipped with a certified streetlight segment controller that enables bidirectional communication over GPRS with the central Streetlight.Vision streetlight monitoring software. It automatically switches on and off the mains using its internal astronomical clock and dims the ballasts during the night to save electricity when less light is needed on the ground.

3. France Telecom (largest telecom operator in France) is providing a Virtual Private Network (VPN) over their GPRS network.

4. The Streetlight.Vision M2M Data Collect software collects, aggregates, transforms and stores data coming from all streetlight segment controllers in a central, open database which is installed at the SPIE IT center, located in Paris (France).


5. The Streetlight.Vision Web Portal provides intuitive end-user Web reports designed for maintenance operators (failure detection and troubleshooting, dimming configuration, installation assistance) as well as for managers (service quality indicators, energy consumption analysis).

Benefits

As demonstrated by the Streetlight.Vision monitoring software and confirmed by the city and by SPIE, the solution brings the following measurable benefits:

• 46% reduction in KWh consumption resulting in an approximate 30% reduction in streetlight electricity costs. The projected electricity cost savings is 80.000 $ per year.

• Projected carbon dioxide savings for the city is 70 tons per year, corresponding to the 46% reduction in electricity consumption.

• Streetlight failure identification within hours, thus providing a 90% reduction in average lamp downtime.

• Prevention of future lamp failures by triggering alarms when the lamp voltage exceeds recommended levels.

• Expected 20% savings in lamp replacement budget due to the way electronic ballasts drive high-pressure sodium lamps.

• Number of onsite maintenance operations is reduced by a minimum 30%. The software enables most of the operations to be performed remotely.

The streetlight segment controller is used to log and report lamp failures, lamp behavior (voltage, dimming level), energy consumption and burning hours. It may later collect information from traffic and weather sensors to adapt lamp dimming levels. The astronomical clock switches on and off lamps depending on the actual position of the sun. Lamps are dimmed at fixed time thanks to the internal scheduler during low activity hours in the night. Significant energy savings result from this highly efficient and recommended method of controlling light levels.

The major of the city is convinced by the measurable financial savings and eco-impact

The mayor of the city is convinced of the benefits of the Streetlight.Vision solution. He agreed to be interviewed for a promotional video where he says: “The SPIE Company has helped provide the municipality with a cost-effective solution which is saving us a lot of money in the next years, while contributing to our strategic sustainable development plan. We’re now extending it to the entire city and promoting it to other cities.”


Streetlight.Vision, towards an online city monitoring center Pushed by the increasing consciousness about climate change and the fast growing price of electricity, cities are keen to deploy solutions such as Streetlight.Vision that have proved to bring energy savings and increased service quality, while providing a clear vision about future possibilities.

Rapid market growth for the LONWORKS based solution

The number of pilot sites in Europe has grown from less than five in 2005 to above 30 in 2006. Streetlight maintenance companies such as SPIE (France) are planning to roll out the solution in more than 50 cities in France and Belgium in 2007. Since September 2006, twelve new streetlight maintenance companies and integrators have started to work with the Streetlight.Vision system and to propose them to their customers in Europe, Canada, the US and China.

Extending the network beyond streetlights

The Streetlight.Vision solution makes it possible to easily extend the solution to collect environmental data such as pollution ratio, air composition, humidity, temperature, traffic and noise levels as well as advertising and information distribution on displays in the streets. Cities can now leverage this valuable information and ability to remote control to increase their knowledge database for strategic planning. With Streetlight.Vision, the investment to install the infrastructure (segment controllers, telecom network, monitoring software) can be reused for many applications.

It is envisioned that more than half of the cities who evaluate the Streetlight.Vision monitoring solution will deploy this solution and will then further extend the networks to other application domains within the next 24 months. Streetlight.Vision aims at becoming the city monitoring solutions.

Streetlight.Vision, a strategic solution for Cities

Thanks to its openness, the Streetlight.Vision system offers a strategic tool for cities to increase its control while optimizing its budgets. It offers a strategic opportunity to service companies to develop new added value services and new profitable business models.
