Germany’s Siemens has submitted the lowest total price for the contract to expand Dubai’s M Station power plant by 600MW.

Siemens’ alternative bid, main price plus option, of AED1,442m ($392m) was lower than the AED1,463m alternative bid submitted by China’s Sepco III. Sepco III’s primary price of AED1,392m was, however, marginally lower than Siemen’s main bid of AED,1395m.

The local Ghantoot and China Power submitted the third and fourth total prices of of AED1,750m and AED1,753m respectively.

The work will involve expanding the capacity of the existing 2,030MW Jebel Ali plant by 600MW.

The contract is one of 1,900MW-worth of power generation projects for which Dubai Electricity & Water Authority (Dewa) has issued tender documents in 2014.

The utility has also issued tender documents in recent months for both the 100MW second phase of the Mohammed bin Rashid al-Maktoum Solar Park independent power project (IPP) and the 1,200MW Hassyan clean-coal-fired IPP.

Dewa has invited 24 prequalified firms to submit bids for the contract to develop the second phase of the solar park. The utility has set a bid submission date of 23 October.

The Netherlands’ KPMG has been appointed as financial adviser and the UK’s Norton Rose Fulbright has been chosen as legal adviser for the planned solar project, which will use photovoltaic (PV) technology. The scheme is scheduled to be fully operational in 2017.

Dewa has invited eight groups to submit proposals by 26 January for the Hassyan IPP. In February, the authority appointed a consortium led by the UK’s EY as adviser for the scheme. Dubai has set a commissioning date of 2020 for the coal plant.
