Awarded as part of the company’s Smart Grid Program, the contract covers integration of the new OMS with Snohomish’s existing Alstom-supplied distribution management system (DMS).

The integration, along with the upgrade to the EMS, will provide Snohomish with an integrated single user interface that will make the system easier to use, maintain and train on, while enabling enhanced situational awareness, especially for network restoration from outages.

Snohomish will use the interface for transmission and distribution control rooms, bringing added consistency across applications.

Snohomish PUD Distribution & Engineering Services assistant general manager Chris Hiemgartner said: "Snohomish PUD is keeping pace with available technology for a modern, integrated electricity grid by working with Alstom across our transmission and distribution control rooms.

"A single software platform will enable ease of integration, more efficient operator training and an overall lower cost of ownership."
Since 2009, Alstom’s EMS has been in service with the Snohomish PUD to monitor and control transmission network.

The EMS upgrade will now allow Snohomish PUD to improve operational efficiency as well as access the National Electric Reliability’s Critical Infrastructure Protection practices for improved system and cyber security.

Alstom implemented its DMS based on its e-terradistribution technology at Snohomish PUD in August 2013.

Snohomish PUD’s Smart Grid Program aims to significantly reduce operations and maintenance costs, while strengthening distribution system reliability.
