Three Clear Training Pathways – Choose the Route That Fits Your Goal

We now offer three focused training routes, each with simple access options.
Whether you need grid compliance knowledge, witness test competence, or PowerFactory modelling skills, you can choose the pathway that matches your role.

All training reflects the latest industry standards, including G99 Issue 2 (2025) and the upcoming storage requirements effective March 2026.

Pathway 1 – Technical & Grid Compliance

(18 Courses | Knowledge & Understanding)
For engineers, consultants, and managers who need a strong grounding in DNO requirements and grid standards.

Covers:
G98 / G99 / G100 · EREC G74 / P25 / P28 ·
BS EN 60909 fault levels · BS EN 50522 & BS 7430 earthing ·
G5/5 harmonics · BESS and grid applications · DNO expectations

Access options:
• One-Day – Quick refresher
• One-Month – Structured learning
• One-Year – Best long-term value

Pathway 2 – DNO Witness Test Engineer

(17 Courses | Competence & Practical Readiness)
For engineers who want to carry out G99/2 witness testing on site.

The online modules deliver around 90% of the required knowledge, focused on protection, commissioning, and test procedures.

After completion, a one-day practical workshop in Derbyshire provides the final hands-on experience needed for live site confidence.

Access options:
• One-Day – Overview
• One-Month – Focused preparation
• One-Year – Full competence pathway

Pathway 3 – DigSILENT PowerFactory Modelling

(25 Modules | Design & Study Skills)
For engineers producing DNO-ready studies, including:

• G99 reactive power capability
• Network modelling and load flow
• RMS dynamic simulations
• Fault level and voltage studies
• Compliance reporting and submissions

Access options:
• One-Day – Introduction
• One-Month – Modelling pathway
• One-Year – Project support

Three Routes. One Simple Decision.

• Grid compliance knowledge
• Witness test engineer readiness
• PowerFactory modelling competence

The only difference is how long you want access.
