- Technical bids were received in November
- Project is second integrated solar project currently out for bid in the kingdom
Saudi Electricity Company (SEC) has extended the commercial bid submission dates for its planned 550MW Duba 1 integrated solar combined-cycle (ISCC) plant.
Contractors now have until 28 May to submit commercial proposals for the combined-cycle component, and the first week of June for the solar part.
This is the second time the submission date for commercial bids has been extended. The original deadline for prices was 2 April. The extension is due to contractors requesting more time to work on proposals. In November, MEED reported that SEC had received technical bids for the contract to build the Duba 1 plant on 16 November.
The Duba 1 ISCC is planned to run on a mix of natural gas and solar energy, and will have a total development cost of $600m. The Duba plant will have a guaranteed total output of 485-550MW, which will include 40MW to 50MW output from the solar system. The planned commissioning date of the plant is 2017.
In January, SEC awarded the US GE the original equipment manufacturer (OEM) contract for the Duba 1 project. GEs order includes two F-class gas turbines, a steam turbine, generators, heat recovery steam generators, condenser, control system and a long-term service agreements.
MEED reported in April 2014 that SEC had dropped plans to develop the Duba 1 scheme as an independent power project (IPP) and was instead preparing to tender the plant as a standard engineering, procurement and construction (EPC) deal. SEC has split the project into two contracts: the EPC contract; and an OEM contract.
Duba 1 is the second ISCC that SEC is moving ahead with, with the utility having also invited contractors to submit commercial proposals for the planned ISCC at the Waad al-Shamal industrial development in the north of the kingdom. The Waad al-Shamal power facility will have a combined-cycle gas component of 1,000MW and a 50MW concentrating solar power (CSP) component.
