ACC was the civil works contractor for the Taweelah A2 750 MW power plant in the UAE, 80 kilometres east of Abu Dhabi. Completed in August 2001, Taweelah A2 has the distinction of being the first Build Own Operate (BOO) project in the UAE in the power sector.

Taweelah A2 is owned by Abu Dhabi Water and Electricity Authority (ADWEA) and CMS Energy, and Siemens was the EPC contractor. The power plant includes three Siemens V94.3A gas turbines, three heat recovery steam generators and two steam turbines.

The project was executed on a fast track basis in order to honour a commitment made by Abu Dhabi Water & Electricity Authority to increase power output by May 2000. Taweelah A2 is now the benchmark for all Independent Water and Power Projects (IWPP) in the Gulf.
