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.
MEED reported in April 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 EPC deal. SEC has split the project into two contracts: the EPC contract; and an original equipment manufacturer (OEM) contract. The OEM will involve supplying, operating and maintaining equipment for the power facility.
SEC issued tender documents to companies for the OEM contract in April, and SEC has now awarded the OEM contract to GE. For the Duba 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 agreeement.
In November, MEED reported that SEC had received technical bids for the contract to build the Duba 1 plant. Prequalified contractors submitted technical proposals for the engineering, procurement and construction (EPC) on 16 November. The deadline for commercial bids is expected to be in January, but a submission date has not yet been set.
