REQUEST FOR EXPRESSIONS OF INTEREST (EOI) AND PRE-QUALIFICATION QUESTIONNAIRE (PQQ) FOR ENGINEERING, PROCUREMENT & CONSTRUCTION SERVICES IN RESPECT OF THE AZURA-EDO IPP GAS TURBINE UPGRADE (POWER) AND EXPANSION (& REPOWERING) OF COMBINED CYCLE GAS TURBINE POWER PLANT IN EDO STATE IN THE FEDERAL REPUBLIC OF NIGERIA.
AZURA POWER WEST AFRICA LIMITED (“Azura Power” or “APWAL”) is the owner of the Azura-Edo Independent Power Plant (“IPP”) located in Benin City, Edo State, Nigeria. The first phase of this IPP was commissioned in 2018 and consists of an open cycle gas turbine (“OCGT”) power plant with a capacity of 461MW. Azura Power is now developing the second phase of the power plant which involves the conversion of the existing OCGT facility into a combined cycle gas turbine (“CCGT”) plant via the installation of a new High Pressure/Low Pressure (“HP/LP”) Condensing Steam Turbine (“CST”) and the upgrading of the existing gas turbines. This conversion and expansion (“the Project”) will add an additional 270MW of power generation capacity.
The Existing Facility
The existing (Phase 1) OCGT facility comprises the following components:
- A 461MW gas-fired open cycle plant, comprising three gas turbines each with a net output at site conditions of 153.6 MW per unit. The gas turbine generator sets are SSC5-2000E and were supplied by Siemens.
- A gas receiving station including scrubbers, filters, metering, dew point heating units and pressure reducing equipment.
- A substation consisting of a 330kV electrical switchyard which is located within the boundaries of the Facility site.
- A 330kV connection into bays at the adjacent Benin North Substation.
- Borehole water supply, storage and connection.
- A Plant Control System (“PCS”) based on a T3000 platform and deemed suitable for expansion to allow for conversion to combined cycle operation. The PCS will be re-designed and/or adapted when the facility is converted to combined cycle.
The Phase 1 facility began commercial operations in May 2018 and currently generates up to 10% of all the power that is supplied to Nigeria’s grid. Further information about the plant can be found at https://azuraedo.com
Phase 2: Engineering, Procurement, and Construction Contractor Role
For the facility’s (Phase 2) CCGT conversion and expansion, Azura Power intends to contract for the services of an engineering, procurement, and construction company (the “EPC Contractor”) with experience in delivering large scale complex projects.
As described overleaf, the appointed EPC Contractor will be responsible for ensuring delivery of a fully wrapped turnkey EPC contract for the provision of two separate and distinct works packages.
- Stream A (GT Upgrade): This package comprises modification and upgrade works to each of the gas turbines to achieve thermodynamical improvements of: Gas turbine gross power output of not less than + 12MW per unit and gas turbine efficiency of +0.9% per unit.
- Stream B (CCGT Conversion): For this package, the appointed EPC Contractor will be responsible for ensuring delivery of the following items:
- the modification and repowering of the existing OCGT plant to a CCGT plant through the introduction of an HP/LP CST together with heat recovery system;
- Modification and expansion of the 330 kV substation to enable power evacuation of the steam turbine generator set;
- All associated tie-in works; and
- The reconfiguring, as required, of other areas of the facility so as to achieve the CCGT conversion.
Streams A and B are expected to run in parallel such that the final interconnection of the Works to the facility should be completed before or on the completion of the GT Upgrade of the last gas turbine.
The EPC Contractor will be responsible for project management, design, engineering, procurement of equipment and materials, construction (including civil works), construction management, training of operations and maintenance personnel, commissioning, start-up, and performance tests for the Project on a turnkey basis.
Azura Power now invites eligible EPC firms to indicate their interest in providing these services. Interested firms must respond to the Pre-Qualification Questionnaire and provide sufficient information to support their qualifications to perform the services in respect of this request for expressions of interest. Additional information may be obtained from, and completed submissions should be returned simultaneously to, both the addresses shown below by 17:00 (Greenwich Mean Time) on 31 March 2023.

In an effort to ensure the highest quality of work, Azura Power will preferentially invite bids from firms that can demonstrate having recently provided EPC services on at least five projects in the past ten years, each project with a value exceeding US$100 million, of which at least two are on a full turnkey EPC basis, and at least two involve the design, procurement, and erection of a Combined Cycle power plant and/or the modification and repowering of an existing open cycle gas turbine power plant to a combined cycle power plant through the introduction of a steam turbine generating set together with heat recovery system, each with individual gas and steam turbines of greater than 100MW. Experience of working in Sub-Sahara Africa is also desirable. Azura Power wishes for this international experience to be complemented with utilisation of in-country expertise.
Following the receipt of the expressions of interest, Azura Power will issue a notification to those pre-selected parties of their pre-qualification. Azura will then issue a Project Tender Package which will further detail the tender process and timescales.
Azura Power will not be responsible or liable for or accept any cost involved in the preparation or submission of expressions of interest and does not bind itself to accept or pre-qualify any such expression of interest.
Acknowledgement and receipt of this EOI and Pre-Qualification Questionnaire, and confirmation of your intention to submit a completed Pre-Qualification Questionnaire is requested using the Form of Acknowledgement together with the signed Confidentiality Agreement. These are to be returned electronically to the above-mentioned email addresses by the 21st of February 2023.
