Grid interconnection compliance

Every grid code. Every engine. One verified answer.

Voltis runs your interconnection compliance studies across PSCAD, PSS/E, and PSLF from a single web platform, cross-checks the results against each other, and reports a verified verdict — with the evidence to back it.

Why this exists

Compliance work outgrew the tools built for it

Interconnection studies are still run the way they were a decade ago — one engine, one code, one engineer's judgment call on scope. As codes multiply and timelines shrink, that approach is the bottleneck.

Codes vary by grid

Every utility and country defines its own interconnection requirements, with no shared test format between them.

Locked to one engine

Studies typically run in a single simulation package, so nothing cross-checks whether the result is actually right.

Scope is a judgment call

Deciding which tests a project needs is still done by hand — slow, and only as good as the engineer making the call.

Reporting is the slow part

Turning results into a report a client or regulator will accept is often the longest step in the whole study.

How Voltis works

One study in, three engines, one verified verdict

Voltis executes grid interconnection requirements from utilities and regulators worldwide. It drives PSCAD, PSS/E, and PSLF from one interface, benchmarks their results against each other, and produces the analysis an engineer can hand straight to a client or regulator.

Benchmarked, unified report
  • A global requirement library, structured by region and utility.
  • Automated execution across every major simulation engine, in parallel.
  • Cross-engine benchmarking that flags disagreement before a regulator sees it.
  • A single exportable report — methodology, plots, and findings included.
  • An AI chat assistant that builds custom report templates and helps analyze the results with you.
The workflow

From project inputs to a signed-off report

Four steps, start to finish — no switching tools, no manual reconciliation between engines.

01

Define the project

Enter the interconnection point, equipment models, and the applicable grid code from any region worldwide.

02

Choose test scope

Select Basic or Comprehensive coverage, or accept Voltis's AI-recommended scope for this specific project.

03

Run across engines

Voltis executes the required studies in PSCAD, PSS/E, and PSLF, and cross-checks the results automatically.

04

Get the analysis

Receive a detailed, benchmarked compliance report, ready to share with the client or interconnecting utility.

Test scope

Pick your depth, or let Voltis recommend it

Every project carries its own risk profile. Voltis offers two fixed tiers, plus an AI recommendation engine that reads the project's specifics and proposes the right scope automatically.

User-selected

Basic

Core mandatory tests required by the applicable code — the fastest path to a first compliance pass.

User-selected

Comprehensive

Full test battery covering mandatory and supplemental studies, for maximum assurance before submission.

Voltis AI

AI-Recommended

Voltis evaluates the project's equipment, code, and interconnection profile, then proposes the tailored test set to run.

Global reach

Built for interconnection codes worldwide

Voltis's requirement library is structured by region and utility, so the same platform that runs a NERC or FERC study today can run an ENTSO-E, AEMO, or CENACE study tomorrow — without re-engineering the workflow.

What's next

Two engineering wings, building our own simulation core

Alongside third-party benchmarking, Voltis is developing native simulation engines in-house — removing dependency on external software licenses over time.

Voltis EMT

Electromagnetic Transient Engine

A native EMT solver for detailed transient and power-electronics studies — an in-house counterpart to PSCAD.

GoalIndependence from third-party simulation licenses

Voltis PS

Positive-Sequence Engine

A native positive-sequence solver for stability and steady-state studies — an in-house counterpart to PSS/E and PSLF.

Proven fluency

Multi-engine fluency, long before Voltis existed

Our engineers have run and cross-validated the industry's full simulation stack for over a decade — the exact expertise now built into Voltis's benchmarking engine.
