Project Facts

Project Challenges

• Extreme molten salt service temperatures — thermal energy storage systems operate with molten salt at temperatures up to 565°C, requiring high-temperature level measurement instruments capable of withstanding extreme heat and corrosive conditions

• Corrosive molten salt environment — molten nitrate salt requires carefully selected materials because long-term exposure at elevated temperatures may cause corrosion and material degradation

• Long-duration thermal storage requirements — tower unit stores 15 hours of thermal energy; trough units store 13.5 hours each, requiring continuous reliable level measurement for inventory management and system control

• Strict EPC documentation requirements — complete calibration certificates, material test certificates, and technical datasheets required for each instrument

• Large-scale EPC project coordination — supply aligned with Shanghai Electric's construction schedule across multiple CSP units (1 tower + 3 troughs) and PV zones

1. Project Overview

Anhui Tiankang Group served as an instrumentation package supplier within the EPC supply chain for the Dubai Noor Energy 1 CSP + PV hybrid project, delivering level measurement instruments and instrumentation accessories in July 2020. Anhui Tiankang supported the EPC supply chain of one of the largest CSP-PV hybrid renewable energy projects globally with engineered level measurement solutions for molten salt thermal energy storage and steam systems.

The project, located in the Mohammed bin Rashid Al Maktoum Solar Park Phase 4 in Dubai, is one of the world's largest concentrated solar power projects and the largest CSP-PV hybrid facility globally. With a total investment of USD 4.4 billion, it is jointly invested by DEWA, ACWA Power, and the Silk Road Fund. Shanghai Electric Group serves as the sole EPC contractor, responsible for engineering, design, procurement, construction, erection, civil works, electrical, testing, and commissioning.

The 950MW project combines 700MW of CSP (1×100MW tower + 3×200MW trough) and 250MW of PV. The tower features a 260-262 meter central tower with 15 hours of thermal storage. Each trough unit provides 13.5 hours of storage. The plant utilizes approximately 550,000 tons of molten salt storage medium across its thermal energy storage systems, which is one of the largest molten salt thermal energy storage systems in the world.

This project represents a landmark deployment of large-scale CSP technology. Major plant systems became operational in December 2023, with commercial operation achieved by 2024. The project provides stable green power for 320,000 local households and reduces carbon dioxide emissions by more than 1.6 million tons annually.

3. Project Technology – Application Context

The following provides background on the project's process technology to help understand the instrumentation application environment.

3.1 Concentrated Solar Power Technology

The project employs a "tower + trough" hybrid CSP configuration. The 100MW tower unit uses a central receiver surrounded by heliostats that reflect and concentrate sunlight. The three 200MW trough units use parabolic mirrors to focus solar energy onto receiver tubes. This combination optimizes energy collection and dispatchability.

3.2 Molten Salt Thermal Energy Storage

The project features one of the world's largest molten salt thermal energy storage systems, with approximately 550,000 tons of molten salt storage medium. The tower unit stores 15 hours of thermal energy, while each trough unit stores 13.5 hours. Molten salt is heated to temperatures up to 565°C in the receiver and stored in hot tanks for continuous electricity generation during nighttime and cloudy conditions.

3.3 Instrumentation Application Requirements

Instrumentation in molten salt thermal energy storage systems must address critical challenges:

• Extreme temperatures — molten salt service up to 565°C requires high-temperature level measurement instruments with specialized materials and designs capable of withstanding prolonged high-temperature exposure

• Corrosive media — molten nitrate salt requires carefully selected materials because long-term exposure at elevated temperatures may cause corrosion and material degradation

• Continuous operation — thermal storage systems operate 24/7; instruments must ensure reliable measurement with minimal maintenance

• Inventory management — accurate level measurement is essential for managing molten salt inventory across hot and cold tanks to ensure dispatchable power generation

• Complete EPC documentation — including datasheets, calibration certificates, and material test certificates

3.4 PV & Hybrid Integration

The 250MW PV component is distributed across unused locations within the 44 km² site for maximum land utilization. The hybrid design enables CSP to provide baseload and dispatchable power while PV contributes lower-cost daytime generation.

3.5 Project Significance

This project is one of the world's largest single-site CSP projects and the largest CSP-PV hybrid facility globally. It supports Dubai's Clean Energy Strategy to achieve 25% clean energy by 2030. For Shanghai Electric, it represents a flagship transition from traditional energy to renewable energy, demonstrating Chinese engineering standards and technology on a global stage.
