About us

Advancing electrical system simulation, from first principles to real-time validation.

SPS (formerly SimPowerSystems) is a rigorously engineered software platform for modeling and simulating electrical power systems. Today, OPAL-RT stewards SPS and connects it to field-proven real-time and HIL workflows, empowering academia and industry to move faster with confidence. 

Our story: From heritage to momentum

SPS began at the Hydro-Québec Research Institute (IREQ) and was distributed globally for more than two decades. As OPAL-RT brings SPS into a new growth cycle, we align its strengths with our real-time platforms—so teams can design offline and validate in real hardware-in-the-loop, using one coherent workflow.

  1. Origin: Developed at IREQ; widely adopted in research and industry. 
  2. Today: OPAL-RT is commercializing and evolving SPS to strengthen an end-to-end simulation ecosystem. 

Why it matters: A single trajectory from modeling → real-time/HIL unlocks faster innovation in renewables, grids, electrified mobility, and aerospace.

What is SPS?

SPS is a block-library environment for modeling generation, conversion, transmission, and consumption—built for transparent control of switching events, EMT fidelity, and deep R&D or education. In OPAL-RT’s ecosystem, SPS models flow naturally toward real-time validation with ARTEMiS and FPGA acceleration via eHS. 

  • High-fidelity EMT studies
  • Controller and protection validation
  • Seamless path to HIL (RT-LAB) and large power-system studies (HYPERSIM)
  • Optional FPGA switching acceleration (eHS) for high-frequency converters

Why Opal-RT + SPS? 

End-to-end, one ecosystem. Teams can design in SPS, then validate timing-accurate behavior on OPAL-RT targets using ARTEMiS and eHS—accelerating cycles, reducing prototyping risk, and improving confidence before deployment. 

Strategic advantages

  • Natively aligned with OPAL-RT’s real-time platforms (RT-LAB/ARTEMiS; optional eHS on FPGA). 
  • Differentiation vs. vendor stacks that fragment offline and HIL workflows. 
  • New software revenue stream and licensing flexibility to expand adoption globally. 

Who benefits

  • Academia (research & teaching), utilities/TSOs, and OEMs in power electronics, EVs, and aerospace.

Community & Education

We invest in an open, global SPS community with forums, webinars, and an education program (LMS, tutorials, and local seminars). Every license can tap structured learning and real-world examples to accelerate mastery.

  • Community forum for knowledge exchange and model sharing. 
  • Academic program with low-cost access, courseware, and lab-ready content. 

Webinars & training dedicated to SPS and its real-time workflows.

Licensing & Availability

SPS is delivered as a subscription with options for students, institutions, professional teams, and enterprises—including floating or node-locked licensing and a guided trial experience.
