Snohomish PUD’s Secure Modern Automated and Reliable Technology (SnoSMART) Program

SnoSMART is an infrastructure and technology project that will deploy smart grid devices across the PUD’s grid and implement state-of-the-art systems to reduce outage times, decrease wildfire risk and improve grid efficiency.

SnoSMART Benefits

Smart devices = Reduced outage times

Smart reclosers coupled with our advanced meter communication network will allow PUD grid operators to isolate outages and re-route power, restoring power to many customers in minutes instead of hours. This technology can identify the location of a problem on the grid and recommend steps to restore as many customers as possible.

Wireless technology = Decreased wildfire risk

Leveraging smart reclosers and a communication network, PUD grid operators will be able to remotely switch equipment to fire safe settings, a job that now requires manual operation by PUD field personnel. This allows the PUD to react quicker to forecasted conditions in high-risk areas, reducing the risk of sparking a fire. It also means fewer PUD vehicles on the road.

Real-time voltage control = Improved grid efficiency

Smart voltage regulators and capacitor bank controls will give PUD operators the ability to better control voltage on our system and react in real-time. This technology allows the PUD to operate the grid more efficiently, saving energy and money.

Grid reliability has become more important than ever

GRIP program funding is an incredible opportunity for the PUD to make important investments in our communities, especially those vulnerable to extended outages.

SnoSMART Equipment

Installation of smart grid equipment will make the grid more automated, remotely controlled and more efficient. The PUD will install more than 900 of these Distribution Automation Infrastructure (DAI) devices over the next four years.

3-Phase Reclosers: Feed data to PUD systems and can be remotely controlled, allowing faults to be quickly isolated.

Single-Phase Reclosers (not pictured): Allow equipment to be placed in wildfire protective settings remotely; also doesn’t release hot metal when open like current fuses used by the industry.

Voltage regulators and disconnect switches on three poles

Voltage Regulators: Automatically adjust voltage incrementally across the grid, maintaining consistency and providing valuable energy efficiency.

Capacitor Bank Controls: Work with other equipment to automatically regulate power and line voltage and communicate with PUD systems.

The implementation of a new Advanced Distribution Management System (ADMS) will give PUD grid operators full control of the new automated devices being deployed across the grid. It will also collect and analyze data from these devices and provide action recommendations to operators. The new system will give our operators greater insight and control of the grid, reducing outage times, decreasing wildfire risk and improving grid efficiency.
