Central tower of 700 MW CSP project by Shanghai Electric and DEWA tops out in Dubai

Once operational, the CSP plant will reduce Dubai's carbon footprint by 1.6million tonnes per year.

“Significant progress” has been made in the 700MW fourth phase of Dubai’s Mohammed bin Rashid Al Maktoum Solar Park, announced as the world's largest single-site CSP project.

A topping-out ceremony for the project's 222-metre central tower was held in mid-January, and welcomed representatives from Shanghai Electric - the project's general contractor - Dubai Electricity & Water Authority (DEWA), Noor Energy 1, and China Construction Third Engineering Bureau.

"SEGC (Shanghai Electric Group Company) showed us their outstanding performance, finishing the concrete solar tower according to schedule, even if they suffered tough challenges along the way," said Enrique Valades Nieto, Noor Energy 1 construction manager.

The project marks a crucial part of the UAE government's Vision 2021 initiative to ensure sustainable and environmentally friendly development.

In addition to Vision 2021, the government also launched the Energy Strategy 2050 Plan, which aims to increase the contribution of clean energy in the total energy mix from 25% to 50% by 2050.

Sustainability is the focus of the project. Shanghai Electric engaged experts and partners to relocate wild animals and 180 mesquite trees across the 40 sq km site to a new wildlife park to minimize the impact of construction.

Concentrated solar power systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight onto a small area.

Electricity is generated when the focused light is converted into heat, which drives a steam turbine connected to an electrical power generator.

The solar power collectors of the 700 MW CSP plant include both tower and tube collectors.

The central tower is the crucial component of the plant and is used for receiving all the focused sunlight from the 70,000 mirrors to increase the temperature to more than 500C, and with this heat produce the steam turbine connected to the electrical power generator.

With a total height of 267 meters, it is currently the world's highest thermal tower.
