From order to energisation
We supply the equipment and can take it all the way into service.
- 01
Specification support
We help set rating, voltages, vector group, losses and accessories against your network and the tender documents.
- 02
Delivery to site
Transport, temporary import and customs planned through to your site, the way we plan our own mobilisations.
- 03
Installation and commissioning
Our programme teams can install, test and energise the equipment, with the records a utility or lender asks for.
