Project Objective

The objective of the Distributed Energy Management and Storage Network (DEMSN) is to maximize the integration of solar PVs and other distributed resources into Hydro One’s distribution system by deploying a battery energy storage system (BESS) and gridOS™ – a suite of smart grid applications developed by Opus One.

The scope of DEMSN project is defined by the following objectives:

  1. Design and develop a unified information and intelligence backbone that enables interoperability between distribution automation components;
  2. Development and deployment of gridOS™ applications which perform situational awareness, adaptive protection and control, and system optimization;
  3. Deployment of a distribution-level lithium-ion battery storage coupled with a four-quadrant power conditioning system.

Company Background

Opus One Solution Energy Corp. is an Ontario-based company with the vision of an intelligent and connected grid. We strive to achieve real-time distribution engineering to unlock grid potential for 100% clean energy and to improve grid reliability, utilization and efficiency. Our focus lies in developing smart grid applications, providing situation awareness, adaptive protection and control as well as system optimization at the distribution level.

In addition to the Distributed Energy Management and Storage Network (DEMSN) Project which is supported by the Smart Grid Fund, Opus One is currently working on projects for integrated urban community energy management, single-site and community microgrids, and volt-VAR optimization systems.

Benefit(s) to Ontario Residents and Businesses

Over the years, Ontario has strongly supported the integration of distributed generation (DG) into the distribution system as it has both economic and environmental benefits. gridOS™ is a suite of smart grid applications developed by Opus One that provides real-time energy management at the feeder level to address DG integration challenges. gridOS™ computes online 3-phase unbalanced power flow to inform the operator of real-time feeder characteristics, alerts/alarms the substation operator and dispatches distributed energy resources during system anomalies such as under/over-voltages and performs optimal power flow with volt/VAR optimization, peak shaving/valley filling and dynamic compensation to optimize the grid. The end result is a distribution system that can accommodate a high level of DGs while maintaining grid reliability, efficiency, power quality and safety.

Project Collaborators

  • Hydro One is the main utility host for project demonstration.
  • eCAMION is the battery energy storage system provider.
  • U of T is responsible for power system studies and simulations.
  • Observer utilities PowerStream, Hydro Ottawa, Horizon, Veridian, and Greater Sudbury Hydro provide technical guidance and value validation of project results.

Project Status

The project was launched in June 2014, and is currently in detailed requirements definition and initial design stage. Key project phases include:

  1. Project Management and Requirements Definition (June 2014 – Aug. 2014)
  2. Solution Design and Development (June 2014 – May 2015)
  3. Site Planning, Construction, Installation, and Implementation (June 2014 – Oct. 2015)
  4. Monitoring, Analysis and Reporting (Nov. 2015 – March 2016)


As a result of the SGF project, partnerships between Opus One and Hydro One, eCAMION and University of Toronto have been established. The SGF project also presents opportunities for future collaborations between the members of the project consortium and observer utilities.
