The Ngonye Falls hydropower project will be contructed by a major international construction contractor under an Engineering, Procurement and Construction (EPC) contract. Under an EPC contract the majority of the risk inherent in the construction of the project is carried by the contractor. This type of contract is commonly used for large infrastructure projects across the world, especially those involving a partnership of the public and private sector.

Western Power is currently running a public tender to select a contractor (or a consortium of contractors) with the necassary experience, capacity and capability to complete the project with the greatest possible value for money. A number of highly experienced and capable international contractors have expressed interest in the project and are participating in the tender.

Construction of the project is due to begin in 2023 and last between 3 to 4 years. At the peak of the construction process as many as 3,000 people will be employed on the site and the contractor will need to have policies and plans in place for training and skills development so that as many of the workforce as possible will be sourced from the local community.
