SOA Category OG10
SOA certification for high/medium-voltage transformation systems, electrical distribution networks and public lighting
The OG10 category covers all works relating to electrical distribution networks and public lighting systems. It is one of the most strategic SOA qualifications for companies operating in the energy and infrastructure sectors. Obtaining this certification requires technical‑organisational capability, appropriate equipment and documented experience on similar works. Costs vary depending on the classification level required.
Electrical networks and public lighting: scope of OG10
OG10 includes the construction, upgrading and maintenance of:
- High‑ and medium‑voltage overhead lines: transmission lines on towers, conductor installation, grounding systems, network upgrades.
- Medium‑ and low‑voltage underground lines: urban/industrial underground cables, duct banks, manholes, replacement of obsolete overhead lines.
- Primary and secondary substations: HV/MV and MV/LV substations with transformers, switchgear, protections, and remote‑control systems.
- Public lighting and traffic lights: roads, tunnels, squares, cycle paths, car parks; also decorative lighting when connected to outdoor electrical infrastructure.
- Grid connections for power plants (with OG9): delivery substations and connection lines for renewable plants such as utility‑scale PV.
- Network refurbishments and upgrades: cable replacement, MV loops, power increases, EV charging predispositions, excavation and reinstatement works.
In short: OG10 is the category for national and local electrical networks—essential for energy, mobility and smart‑city development.

- OG9 – Energy generation plants (thermal, hydro, wind, PV). OG10 covers grid connection and distribution.
- OS9 – Luminous signage and traffic‑safety systems (variable‑message panels, traffic lights). Distinct from OG10, which covers electrical infrastructure and public lighting.
