Illustration: OS Power trailer-mounted and containerized gensets at a construction site

Solution

Site power before grid connection

Grid connection takes months or years, but the site has to start now. Containerized gensets and storage power construction and the first phase, and after grid connection they become its backup.

Key figures

up to 100 MW

supplied within 4 months depending on project location

Why sites wait

Connection lead times

Capacity at the right point of the grid becomes available in a year or later.

Construction

Cranes, concrete, welding and site cabins need power from day one.

First phase

A data center, plant or camp wants to start operating before the substation is commissioned.

Solution

How it works

A power module of containerized gensets and storage: primary source first, backup after grid connection.

  1. ConstructionTrailer-mounted units power the construction site.
  2. First phaseA containerized power module with storage feeds the site as the primary source.
  3. Grid connectionThe grid becomes the primary source, gensets become backup.
  4. BackupThe same units serve as site backup, storage reduces peak demand from the grid.

After grid connection the gensets move to backup duty without replacing equipment.

Lead times depend on power rating, design and plant workload; they are confirmed in the commercial proposal.
