## How to select an EPC contractor

EPC means engineering, procurement and construction. Compare contractors by project technology, country, voltage level and contractual delivery scope.

## Directory methodology

This directory presents company profiles, not a scored ranking or certification. Company-wide experience may include engineering, EPCM, equipment supply and consortium roles. Confirm the exact role, current qualifications and project references with the official company before shortlisting.

## What should an EPC enquiry include?

Specify the project country, capacity, grid voltage, single-line diagram, site conditions, scope boundaries, target schedule and acceptance tests. Clarify who owns permitting, civil works, grid studies, commissioning and performance guarantees.
