Grid design takes weeks

A typical grid-connection engineering study today requires months of coordination between consultants, the regulator and the grid operator. Every revision restarts the process.

  • 6–8

    weeks for a typical interconnection study

  • €50K+

    average external-consultant engagement

  • v12+

    diagram revisions per project

A collaborative online grid lab

TestBeforeInvest brings design, simulation and reporting into one collaborative environment — available to the entire team from day one.

  • Real-time collaboration

    Multiple engineers work on the same diagram at the same time, with every edit traceable to its author.

  • Versioning and audit

    Every calculation, every edit and every PDF export is preserved — and revertable with one click.

  • Regulator-ready

    Export PDF reports aligned with KEVR and ESO requirements — no manual formatting needed.

  • Bulgarian from day one

    UI and documentation authored in Bulgarian — not translated, but designed for Bulgarian engineers.

What TestBeforeInvest does

Eight tools for designing, analysing and reporting on electrical grids — all in one platform.

  • Grid modelling

    Live

    Design lines, substations and transformers in a visual editor.

  • Power-flow (AC/DC)

    Live

    Compute bus voltages and line loadings across scenarios.

  • N-1 contingency analysis

    Live

    Simulate failure of any element and assess grid resilience.

  • Load forecasting

    Partial

    Seasonal and daily consumption profiles for capacity planning.

  • Regulator-ready PDF reports

    Live

    Generate submission-ready documents aligned with KEVR and ESO requirements.

  • Roles and permissions

    Live

    Granular rights for viewing, editing and approving projects.

  • Audit log

    Live

    Full traceability — who changed what and when, with one-click revert.

  • Multi-company workspaces

    Partial

    Organisations and sub-units with isolated data and shared templates.

Connect a solar park in 30 minutes

From building your grid to a regulator-ready report — a real-world TestBeforeInvest scenario.

  1. Build the grid

    Lay out your grid directly in the editor — place lines, substations and loads on the map and TestBeforeInvest validates the topology as you go.

  2. Add the solar park

    Drop the new asset on the map, set installed capacity, generation profile and point of interconnection.

  3. Regulator report

    Run power-flow and N-1 analysis. Generate a PDF report ready for submission to KEVR or the grid operator.

Why not AutoCAD or a consultant

TestBeforeInvest doesn't replace your engineering team — it frees them from repetitive work.

vs. AutoCAD

  • Simulation, not just drawing
  • Cloud collaboration
  • Versioning without manual naming
  • Reports in one click

vs. DIgSILENT / PowerFactory

  • No local install
  • No tens-of-thousands-euro licence
  • Regulator-ready for Bulgaria
  • Hours to onboard, not weeks

vs. external consultant

  • Keep your data in-house
  • Results in hours, not months
  • Reproducible without new POs
  • Full traceability

Built for auditors and regulators

Every calculation, every decision and every user — fully traceable.

  • Regulator-ready PDF reports

    Submission-ready documents aligned with KEVR and ESO requirements.

  • Audit log

    Every diagram and parameter change captures author, timestamp and reason.

  • Roles and permissions

    Granular rights for viewing, editing and approving — scoped by team and project.

  • Part of UDIH 4 EU

    An EU co-funded initiative for digital transformation of utility services. EU-hosted, GDPR-compliant data handling.

Pay for what you simulate

No seat licences, no annual subscriptions. Token-based pricing — for actual simulation time used.

Frequently asked questions

  • What is the relationship to UDIH 4 EU?

    TestBeforeInvest is part of the UDIH 4 EU initiative (BG16RFPR002-1.002-0008) — the Hub for Digital Transformation of Utility Services, co-financed by the European Union through the European Regional Development Fund. Our role within the initiative is the cloud simulation platform for the electrical sector.

  • Is TestBeforeInvest ready for KEVR submission?

    Yes. PDF reports are structured per KEVR requirements for grid-connection studies. Format and content update whenever regulation changes.

  • Who owns our data?

    You do. TestBeforeInvest is a processor, not an owner. Your data is stored in the EU; you can export or delete it at any time.

  • How much does it cost?

    Pricing is token-based. Enterprise customers get a custom quote — contact us for details.

  • Is the interface in Bulgarian?

    Yes. The application ships Bulgarian from day one. An English UI is on the way.
