Dubai Commissions World’s Tallest Solar Power Tower

The lifting and installation of the Molten Salt Receiver (MSR) on top of the world’s tallest solar power tower is complete.

The 262.44 metre high tower stands at the Mohammed bin Rashid Al Maktoum Solar Park in Dubai, the largest Concentrated Solar Power (CSP) project in the world.

The CSP project is part of the 4th phase of the solar park. The 950MW 4th phase is based on the Independent Power Producer (IPP) model with investments totalling AED 15.78 billion ($4.3 billion).

The Managing Director & CEO of Dubai Electricity and Water Authority (DEWA), Saeed Mohammed Al Tayer said the project is UAE’s contribution towards the building of future of the world with environment-friendly solutions for sustainable development.

Al Tayer stated that the smoothness and continuity of construction work over the past period for this strategic project, despite the coronavirus pandemic. It has taken one and a half years to complete 60% of the CSP tower and without injuries.

The concrete part of the solar power tower is now complete at a height of 222 metres. The MSR was built and assembled while the tower was being built.

Abdul Hamid Al Muhaidib, Executive Managing Director of Noor Energy 1, briefed His Highness on the progress and installation of the MSR. Noor Energy 1 is owned by DEWA, the Silk Road Fund, which is owned by the Chinese Government and ACWA Power from Saudi Arabia.

“ACWA Power is proud to partner with DEWA and Silk Road Fund and support all efforts to make the Dubai Clean Energy Strategy 2050 a reality. Today, we reached another significant milestone in the world’s largest CSP plant, Noor Energy 1. We have completed the lifting of the Molten Salt Receiver in a record time, keeping the highest standards of safety despite the impact of the COVID-19 pandemic and many other challenges. This is yet another demonstration of ACWA Power’s commitment in to the solar industry and the endeavours made in the region to achieve a clean energy future,” said Mohammad Abunayyan, Chairman of ACWA Power.

The MSR is the centre and the most important part of the CSP plant. It receives solar radiation and turns it into thermal energy. Up to 50% of the overall project’s first phase has been completed. This includes the solar power tower, the parabolic basin complex, and the photovoltaic solar panels.

The fourth phase of the solar park combines CSP and photovoltaic technology and is rated for 950MW. It will use 700MW of CSP, 600MW from a parabolic basin complex, 100MW from the solar power tower and 250MW from photovoltaic solar panels.

On its completion, the project will have the largest thermal storage capacity in the world of 15 hours, allowing for energy availability around the clock.

The fourth phase will provide clean energy for 320,000 residences, will reduce 1.6 million tonnes of carbon emissions a year and covers 44 square kilometres.

The Mohammed bin Rashid Al Maktoum Solar Park is the largest single-site solar park in the world based on the IPP model, with a planned capacity of 5,000MW by 2030 and investments of up to AED 50 billion ($13.6 billion).

A Power Purchase Agreement was signed in March 2020 for the 900MW photovoltaic fifth phase based on the IPP model. It will become operational in stages starting in the third quarter of 2021.
