Dubai Electricity & Water Authority (Dewa) has invited bids to build a 400kV substation and associated works for the Hassyan coal-fired independent power project (IPP).

Contractors have until 30 September to submit prices.

The substation will be used to link the 1,200MW Hassyan plant to the grid.

MEED reported in April that a consortium of Saudi Arabia’s Acwa Power and China’s Harbin had submitted the lowest tariff price for the IPP.

The Saudi developer submitted a tariff price of 5.177 cents a kilowatt hour (kWh) for the 1,200MW project, and also submitted an alternative proposal for a 1,800MW plant with a levelised cost tariff of 4.998 cents a kWh. Dewa received bids from four bidders on 30 April.

Dubai has set a commissioning date of March 2020 for the first 600MW unit of the coal plant, with the second to come on stream a year later.
