Dubai Electricity & Water Authority (Dewa) has extended the bid submission date for offers for the contract to undertake studies on the potential implementation of geothermal, tidal wave and ocean current schemes to produce renewable energy.

The deadline for bids for the prefeasibility studies has been extended from 17 July to 31 July to allow bidders more time to work on submissions.

The authority has asked consultants to submit proposals for the contracts to carry out prefeasibility studies on geothermal technology for power generation and desalination projects as well as the potential for tidal wave and ocean current technology for power generation.

Dubai is seeking to conduct the studies to widen its potential renewables production, having focused on solar energy in its renewable energy projects to date.

The emirate has set a target for 25 per cent of its electricity production to come from renewable energy sources by 2030, with 75 per cent of its power set to come from clean energy sources by 2050.

The emirate’s target for 25 per cent of renewable energy by 2030 will come from the planned 5,000MW capacity of its Mohammed bin Rashid al-Maktoum (MBR) solar park.

On 1 May, Dewa received three world record-low tariffs for the proposed 800MW photovoltaic (PV) solar third phase of the park. In June, the utility announced it was planning for concentrated solar power (CSP) to contribute 1,000MW of the planned 5,000MW of solar energy by 2030.
