11kV & 33kV grid connection and substation construction in Nigeria

Getting a site onto the national grid in Nigeria is rarely just "install a transformer". It is a chain of approvals, materials, civil works, line work, testing and coordination with the distribution company (DisCo) — and if one link slips, the site stays on diesel. Ionir Integral runs the whole chain, from the first load survey to the moment the meter starts counting.

What a turnkey grid connection includes

We deliver 11kV and 33kV connections for telecom towers, factories, warehouses, estates, schools and places of worship. Every job follows the same documented path:

1. Site & load assessment — we measure actual and projected demand, then size the transformer and protection so you are not paying for idle capacity.
2. Design & DisCo approval — single-line diagram, route survey and application to the DisCo covering your area (in Lagos, typically Eko or Ikeja Electric).
3. Procurement — transformers, concrete poles, conductors, insulators, isolators and fuses from approved manufacturers.
4. Construction — pole planting, line stringing, substation erection, earthing and LV distribution.
5. Testing & certification — insulation resistance, earth resistance and transformer tests, followed by NEMSA inspection.
6. Energisation & handover — coordinated switch-on with the DisCo, metering, and a handover pack with as-built drawings and test results.

Pole-mounted or ground-mounted?

Most telecom sites and small commercial loads are best served by a pole-mounted substation: quicker to build, smaller footprint, lower civil cost. Larger industrial loads usually need a ground-mounted or compact substation with proper switchgear. We recommend the option that meets your load and the DisCo's standards at the lowest lifetime cost — read our comparison.

Proof you can check

Every stage is recorded with geotagged, time-stamped photos, so remote project managers and investors can verify progress without travelling to site. See examples in our project field log — including grid connections delivered for ATC Nigeria, IHS Towers and Pan African Towers.
