ACWA 1,300-1,500 MW Syrdarya CCGT Project

Country: Uzbekistan
Client: ACWA
Year: 2020 / Ongoing

ACWA is developing a 1,300-1,500 MW CCGT project through bilateral agreement with the GoU and signed a 25-year PPA in March 2020 on a BOOT basis. GoU is also developing another similar CCGT project in the adjacent area with the support of IFC. The proposed site area for the projects are located near the existing Syrdarya TPP, which with the capacity of 3,050 MW is the largest power plant in Uzbekistan. Recently 4 units or a total of 950 MW of the Syrdarya TPP have been rehabilitated and they are expected to be used for regulated capacities even though other old units are to be decommissioned in line with the implementation of new CCGT power plants. All of these factors make the Project technically the most complex in Uzbekistan power system.

The Client has requested the Consultant to provide services for a number of packages including:

  • Power evacuation study for both new CCGT power plants [ACWA+IFC] with up to 3 GW capacity;
  • Ground investigation studies covering geotechnical, topographic, hydrological, meteorological and water supply for ACWA CCGT project;
  • ESIA for the ACWA project together with the lead ESIA Consultant of ACWA.

Services provided:

  • Analyse and identify technically reliable options for connecting the new CCGT plants to the Uzbekistan transmission system [expected to be at 500 kV and 220 kV levels];
  • Perform steady-state analysis including load flow, short-circuit, N-1 and N-2 contingency;
  • Evaluate the impact of the proposed project on the Uzbekistan/Central Asia power system;
  • Design the power evacuation infrastructure;
  • Develop interconnection concept for the selected option;
  • Identify and outline mitigation measures for ensuring grid performance during CCGT plants operation;
  • Develop principles for protection, automation and telemetry for dispatching purposes;
  • Develop line(s) routing for the selected option;
  • Prepare Bill of Quantities;
  • Perform high level Cost Estimates for selected connection arrangements.
  • Geotechnical Investigation under ASTM standards
  • Topographic Survey
  • Hydrological Study
  • Meteorological Study under ASHRAE standards
  • Water Supply Study
  • Baseline report of technical studies, including: Air and Noise Monitoring; Soil Quality; Water quality; Biodiversity; Archaeological and cultural heritage; Social Economic Study; Regulation review.
  • Organization of public consultations and disclosure meetings;
  • Application for National EIA (Preliminary Statement of the Environmental Impact);
  • National EIA Statement for Submission (this includes the stage 3 of Submission stage);
  • Support approval of the National EIA Statement.
