Nubaria Combined Cycle Power Plant I,II & III
		

				

				

				

							
Project Overview:
Nubaria Power Station 750 MW Combined Cycle Project significantly expanded Egypt’s electricity generation capacity through a phased construction of combined cycle power plants, starting in 2002. These plants utilize both gas and steam turbines to maximize efficiency and output, meeting the increasing energy demands of the region.
The project comprises three distinct phases:
  • Nubaria I & II Power Plant (1500 MW): Consisting of two modules, each delivering 750 MW. Each module includes two 250 MW combustion turbine generators (CTGs) that feed exhaust gases to heat recovery steam generators (HRSGs). Steam from the HRSGs powers a 250 MW steam turbine generator (STG). The plant utilizes dry low-NOx (DLN) combustors for emission control and draws cooling water from the Nubaria Canal.
  • Nubaria III Power Plant (750 MW): A single module delivering 750 MW, with two 250 MW CTGs feeding HRSGs to power a 250 MW STG. It also employs DLN combustors and an inlet air filtration system. Cooling water is sourced from the Rayah El Nasery Canal.
These power plants play a crucial role in supporting Egypt’s economic development and improving the reliability of its electricity supply.
						

				

					

		

					

		

				

						

					

			

						

				

					

			

		

				

				

				

				

							
Key Components:
Nubaria Power Station project includes the following key components:
  • Gas Turbines: High-efficiency gas turbines to generate electricity.
  • Steam Turbines: Utilizing waste heat from the gas turbines to generate additional electricity.
  • Generators: Converting mechanical energy into electrical energy.
  • Cooling System: A critical system for dissipating heat, including the circulating water piping system supplied by ECPC.
  • Control Systems: Sophisticated systems for monitoring and controlling the power generation process.
  • Transmission Infrastructure: Connecting the power plant to the electricity grid for distribution.
  • Auxiliary Systems: Supporting systems for fuel supply, water treatment, and other essential functions.
						

				

					

		

				

			

							

		

					

		

				

						

					

			

						

				

					

			

		

				

				

				

				

										

																					

										

							

				

					

		

				

			

						

				

					

			

		

				

				

				

				

							
ECPC’s Scope of Work:
ECPC’s involvement in the Nubaria Power Station project spanned multiple phases:
Phase I & II (2003/2004):
ECPC supplied over 4,000 meters of Reinforced Concrete Cylinder Pipes (RCCP) for the circulating water piping system. These pipes, with diameters of 1,800mm and 2,500mm, were designed for a maximum pressure of 5.50 bars. They were used for the intake and discharge piping systems, as well as special fittings, connecting the circulating water pump house to the power block and the power block to the siphon box.
Phase III (2007/2008):
ECPC again supplied the circulating water piping system, providing over 3,600 meters of RCCP with diameters of 1,800mm and 2,500mm. These pipes were used for open-cut laying and vertical connections within the power plant’s processes.
