Landis+Gyr jointly with Con Edison have been working on a project to manage energy use at plug-in electric vehicle (PEV) charging stations.
Con Edison is a utility that serves New York City and Westchester County and has installed Landis+Gyr’s L510 load control switches at 50 single-family homes as part of a pilot program.
According to the program, the utility analyze sub-metering technologies, conducting a study on how the customers respond to requests that they charge their vehicles at a fixed time of the day when demand for electricity is low.
It will also provide remote control of high-consumption appliances, the L510 uses built-in metrology to compute and report energy usage.
All these efforts are expected to enhance applications in monitoring and controlling charging stations.
Later, Con Edison will detail on a report gauging the accuracy and usefulness of the metering technology with a proposal for next action to be executed by March 31, 2015.
As electric vehicles become more popular in New York City and Westchester County, company expects to meet the demand for electricity and continue to provide the customers with industry-leading reliable service, said, John Shipman, department manager, Demand Management and Customer Engagement, Con Edison.
Options such as variable rates, which reward customers for charging vehicles at times when demand for electricity is lower will support in maintaining the reliable service New Yorkers need, added Shipman.

Landis+Gyr’s load management technology consists of hardware and software designed for managing EV charging. Utilities can monitor, control and respond to signals from charging stations, in addition to using information to implement a variety of tariffs.
As electric vehicles become more common, utilities will need more visibility into the impact on the distribution grid. An intelligent switch like the L510 can serve multiple functions for the utility since it knows how much energy the appliance being controlled is consuming at any given time, said Clark Pierce, vice president, general manager, Landis+Gyr’s load management business.
This technology provides the utility with more options and value for managing and balancing system load throughout the day, added Pierce.
