California utility selects Landis+Gyr for grid optimisation


The partnership allowed the Burbank city (California) utility to deploy the firm’s advanced grid analytics technology, Asset Loading Solution, to monitor and manage its grid assets in real time.

Calvin Clark, Electrical Engineering Associate at BWP, said: “By using the technology, we can now run detailed analysis on transformers, and balance the load when needed to extend the life span of our transformers.

“Predictive analytics enables us to deliver services reliably and provides us the opportunity to avoid unnecessary overtime spent on responding to transformer outages,” added Clerk.

The solution is said to have allowed the utility to experience zero unplanned outages this summer.

Landis+Gyr claims that the technology helps utilities to ensure grid reliability and improve customer services through monitoring the performance of grid assets in a cost effective manner.

[quote] Connaker, general manager of Landis+Gyr’s Analytics Solutions said the platform supports a utility’s existing grid investments in AMI and intelligent devices.

“Not only does this solution identify asset issues, it also recommends optimized asset management scenarios to proactively prevent outages,” added Connacker.

The technology is designed to provide system operators with a map-based view of asset loading from the substation to transformers, a functionality which helps to identify and minimize assets failure.

To date, the solution is being used to analyse over 170,000 miles of distribution lines.

Smart grid deployments

In mid-February, Landis+Gyr announced that it has signed a contract with US state of Alabama’s electric utility co-operative, Baldwin EMC, for the installation of a load management system.

The system falls under Landis+Gyr’s Gridstream Customer Intelligence solution providing two-way communication with distribution equipment including load control switches and thermostats.

Under the contract, Baldwin EMC is deploying the system in four residential demand response programmes together with 20,000 devices managing 19MW of load.

The deployment of the load management solution comes after Landis+Gyr completed integrating the system’s operating system PowerCenter with NISC’s Customer Information System.

Landis+Gyr said, “The integration synchronises programme enrolment and management of Baldwin EMC’s four demand response programmes, while automating device installations and service calls.” [Landis+Gyr extends contract with US utility for AMI solution].

Alan Schott at Baldwin EMC said: “Our Centsible Power demand response programme offers four options for members to receive credit for water heater and HVAC control and provides access to online and mobile applications so they can monitor and control attached equipment and stay engaged”.

Schott added: “We are projecting cost savings from the program of more than US$22 million over the next decade and all members benefit from these reduced costs.”
