Puget Sound Energy selects Landis+Gyr to deploy smart street lights


US utility Puget Sound Energy has selected Landis+Gyr to add street light control capabilities to its smart grid and advanced metering infrastructure (AMI) programme.

Using Landis+Gyr’s Gridstream AMI network, Puget Sound Energy (PSE) plans to deploy 25,000 street light controllers over the next five years. 

The smart controllers will perform a variety of functions including control of lighting intensity to boost energy efficiency and metered billing of street lights using the metrology in controllers.

As part of the agreement, Landis+Gyr will host the street light control software used to program, monitor, and control the lights. Billing data will be processed through the utility’s meter data management system.

“Intelligent street light control presents another way utilities can leverage Landis+Gyr’s Gridstream Connect platform to manage assets more efficiently, strengthen network performance and cost-effectively add sensing and monitoring across the distribution system,” said Jay Lasseter, Vice President of Industry and Growth at Landis+Gyr.

With the ability to measure consumption using the billing-grade metrology in the street light controller, PSE will be able to more effectively gauge the energy being consumed and also use adaptive controls to lower power consumption in identified locations and during specific times of day.

Puget Sound Energy serves more than 1.1 million electric customers and nearly 900,000 natural gas customers.
