US public utility Seattle City Light partnered with energy management solutions firm Landis+Gyr to improve grid operations with advanced analytics solution.The utility serves some 750,000 consumers in Seattle and is integrating Landis+Gyr's Advanced Grid Analytics (AGA) platform with its energy distribution system.

Smart grid analytics

In a press statement, the solutions provider claims that its AGA system will help Seattle City Lights gather big data from smart meters, grid sensors and GIS, process and translate it into information for use in improving daily real-time operation and management of grid system.

The project is divided into two phases through to 2018 and is expected to help the utility improve its services by optimising load and voltage management, reduce technical and non-technical losses and avoid the occurrence and duration of power outages.

In addition, Landis+Gyr's cloud-based managed software-as-a service solution is expected to help Seattle City Light to manage its grid-integrated renewable energy resources, reduce operational costs and improve the lifespan of its grid assets.

"The first phase of the project includes Model Validation and Reliability Planner to improve the accuracy of the connectivity model, save engineering time and optimise future reliability improvement projects. The next phase will include the Asset Loading application for capacity planning and Revenue Protection to help the utility detect and reduce revenue losses more efficiently," according to a company statement.

Laurie Hammack, Senior Manager of Power System Planning at Seattle City Light, added: “Our goal is to extend the value of our advanced metering and smart grid investments by using analytics to improve reliability, planning and asset management.”

In a deal reached between the two companies in 2016, Seattle City Light deployed Landis+Gyr's mesh network to provide connectivity between smart meters, distribution devices and intelligent sensors. [Seattle City Light selects Landis+Gyr AMI grid solution]

Smart meter business

The news follows an announcement made in early March by Toshiba, the owners of Landis+Gyr, that they are preparing to sell their subsidiary for $2 billion.

According to Reuters, Toshiba has plans to sell smart meter group Landis+Gyr, in a bid to raise $2 billion in capital following a “major writedown on its US nuclear unit last month.”

Reuters adds that Toshiba announced a $6.3 billion writedown on its US nuclear business last month, wiping out its shareholder equity and causing it to seek divestments to create a buffer for any fresh financial problems. Read more...
