ACWA and Abengoa share updates on DEWA's 700MW CSP project
2020.04.09 From: CSPFocus光略咨询
In terms of the tariffs of solar power projects ACWA Power has made in recent years, for example, in the same Dubai's Mohammed Bin Rashid Al-Maktoum Solar Park, we have moved from USD 5.8 cents/kWh to 1.69 cents/kWh, which is more than 70% off for the Phase 2 and Phase 5 PV projects. While in the CSP, we have reached more than 60% of lower tariffs between the first project that we had in CSP---South Africa’s 50MW Bokpoort Parabolic Trough CSP project and the Phase 4 in Dubai.
We have been talking about the energy transition toward a global energy with zero carbon emissions, and this huge 950MW CSP-PV solar project is really supporting this transition using renewable energy.
The project is implemented and owned by a company named Noor Energy One to meet the requirements of the law in UAE. Together with 700MW CSP, another 250MW PV project forms a total capacity of 950MW for the Noor Energy 1 project. The project takes use of three technologies to produce 950MW of clean energy — 600MW from three parabolic trough CSP plants, 100MW from a solar tower, and 250MW will be generated from photovoltaic panels.
8 of the world records for CSP industry made by Noor Energy 1
World largest single-site investment project in CSP based on IPP model---USD 4.4 billion (AED 15.78 billion)
World largest capacity of single CSP+PV project---950MW
World largest area of single CSP+PV project---44 square kilometers
World biggest quantity of molten salt used in single CSP project---550,000 tons
World tallest CSP tower---260m
World leading tower wireless heliostat technology---70,000 heliostats
World largest trough in commercial CSP project---8.2m
Most competitive LCOE---USD 7.3 cents /kWh, which can compete with fossil fuel electricity in UAE.
The project will include technologies from a wide range of suppliers, of which Spain’s Abengoa is responsible for CSP Parabolic Trough tech and USA’s BrightSource for CSP Tower.

Mohammed bin Rashid Al Maktoum Solar Park
The Mohammed bin Rashid Al Maktoum Solar Park is the largest single-site solar park in the world, based on the IPP model. It will generate 5,000MW by 2030 with investments of up to AED 50 billion. The 13MW photovoltaic first phase became operational in 2013. The 200MW photovoltaic second phase of the solar park was launched in March 2017. The 200MW first stage of the 800MW photovoltaic third phase became operational in May 2018. The third phase project has been awarded to ACWA Power, and it consists of three units, each unit has 200MW or 300MW capacity, totaling 800MW PV.
For the thermal storage, so, we are considering 15 hours for the central tower unit and then 12.5 hours for each of the parabolic trough units.
Given the huge area of the project with around 44 square kilometers, it’s very far to connect one unit from one side to the other. We have several switching stations which are under construction in the project and will connect from them to the 400kV DEWA substation.
Considering the complexity of the project technically and financially and even contractually, there was a huge amount of advisors checking and reviewing the project making sure that this project is sustainable and physical.
One of the important points to highlight in this project is that the project has more than 1.6 million tons per year of saving in carbon emissions, and power more than 320,000 residential units in Dubai.
The work is progressing according to the set timetable for this project that will contribute to Dubai’s transformation into a global clean and renewable energy hub, and accelerate its shift towards solar power.

The expected construction duration lasts 48 months, meaning the overall 700MW CSP project will be completed by the end of 2022 in four years. Separately, the first parabolic trough CSP plant is planned to be operational on August 22, 2021, in 32 months, tower CSP plant finished on November 22, 2021 in 35 months, and the second and third parabolic trough plants to be completed by the end of the year of 2022.
The first key milestone that has been achieved in 2019 is the central tower, the civil construction part of the concrete tower has been achieved. Currently we are erecting the MSR and then the lifting is going to start by May 2020.
We have reached 3,200 employees on site in total as of the beginning of 2020, and reached more than 4.2 million safe man hours, which is a key point in terms of safety in the project.
As you may know, the EPC Shanghai Electric is Chinese, the project company is from Dubai and the technology providers are from Spain or UK and other subcontractors and key parties are in other locations. Coordination between them was little bit hard and challenging at the beginning but then it went smoothly on the execution of the project same as for other items.
Another big challenge is the huge amount equipment and materials to be ordered. The availability in the market may not be enough or the market is not used to provide such availability of equipment. We had to work very hard at the beginning together with EPC contractors to ensure that manufacturing is going as per plan especially for the key equipment.

Based on the detailed share by Meriem, I would like to add some information on the parabolic trough plants.
We have a contract with very serious guarantees in terms of production performance, so the purchase and engineering are very important.
As for the status of the PT plants right now, the engineering is closed for PT 1 and all the basic engineering for the three units is almost complete. We have closed all the purchases in terms of mirrors, structures, tubes and controlling system for all the three units. It was really challenging to close some of these purchases, because the contracts were really huge.
We have to analyze the production capacity of suppliers to ensure that they were going to comply with the delivery terms. We are going to construct this in 26 months so it’s not an easy task. What else, in terms of logistics it is really important to analyze during the procurement phase how we are going to transport all these materials since we’re talking of more than 8 million square meters of mirrors.
We’re expecting to produce more than 150,000 tons of steel structure and install more than 250,000 units of receiver tubes.
