Saudi Electricity Company (SEC) is still in negotiations with bidders for the planned 3,780MW integrated solar combined-cycle (ISCC) power plant in Taiba.

MEED reported in March that the state utility had received bids from nine firms for the owner’s engineer (OE) role on the scheme.

The US’ Black & Veatch submitted the low bid for the deal.

The second-lowest price was submitted by Sweden’s AF Consult, followed by Germany’s Lahmeyer in third place.

Contractors are currently working on technical proposals for the main engineering, procurement and construction (EPC) package for the Taiba plant, which will be located in the western Medina region of the kingdom. SEC has extended the submission date into July, the second time the deadline has been extended. The original submission date was mid-February.

The Taiba ISCC is being procured through a handful of packages, similar to the model that SEC employed for the Duba 1 ISCC, which was awarded in 2015.

The utility received bids for the gas turbines package on 18 April, and is still currently evaluating proposals, according to sources close to the scheme.

The facility will have a combined-cycle capacity of 3,600MW as well as a 180MW solar component. It will be one of the largest generation facilities in the kingdom, and will cost upwards of $3bn to build.
