UK consultant Mott MacDonald has been hit by the decision to put a £6.1bn power project it is working on in Dubai on hold

The Dubai Electricity and Water Authority (DEWA) is understood to have deferred the tendering process on the Hassyan power complex by at least eight months.

The power and desalination project, which is divided into two phases, plans to have a combined capacity of 3,000MW of power and 200 million gallons of water per day.

Mott MacDonald is the lead consultant for the first phase and German engineering firm Lahmeyer is handling the second.

The first phase was put on hold earlier this year while delays to the second phase emerged last week.

It is thought the client stalled the scheme in the hope of getting a better price from contractors later in the year.
