Project Overview

The Al Dur Independent Water and Power Plant was established to help meet the growing demand in Bahrain for clean, reliable and competitively-priced power and water. The project entailed the construction of a Combined Cycle Gas Turbine Power Plant and a Reverse Osmosis (RO) technology Desalination Plant, together with all support facilities such as seawater intake and discharge structures and gas connection facilities.

With a capacity to produce 1,234 MW of power and 218,000 m3 per day of the highest quality water in the GCC, Al Dur became the largest independent power generation and water desalination plant in the Kingdom of Bahrain, making it a landmark project and a critical part of the Kingdom’s economic infrastructure.

GPZ was appointed as the main contractor, under the EPC contractor Hyundai Heavy Industries (HHI), for 3 contracts of the project: (1) Civil works for the Power Plant, (2) Building works for the Power Plant, and (3) ­­Building works for the RO Desalination Plant. The works involved close co-ordination with the EPC contractor for the installation of various plant and equipment.
