SHANGHAI, June 12, 2021 /PRNewswire=KYODO JBN/--

Shanghai Electric ("Shanghai Electric" or "the Company") (601727.SS and

02727.HK) announced that the first molten salt tank hydro test for the

Parabolic Trough Plant-II (PT2) of the fourth phase of Mohammed bin Rashid Al

Maktoum Solar Park was carried out on May 9, the positive results of which laid

a crucial foundation for the next phase of the molten salt system commission.

The test was followed by finalized molten salt pipeline installation inside the

Concentrated Solar Power (CSP) tower, marking another key milestone in

construction progress.

The fourth phase of Mohammed bin Rashid Al Maktoum Solar Park is the largest

single-site Concentrated Solar Power (CSP) project in the world, which uses

world-leading hybrid solar energy technologies to generate 950MW of clean

energy, including a 100 MW CSP tower plant, three 200 MW parabolic trough CSP

plants and 250 MW of photovoltaic (PV) capacity.

The solar tower, standing 260m-high at the center of the CSP tower plant site,

will also be the world's tallest structure of its kind. Upon completion, the

combined thermal energy storage of the solar tower and parabolic trough plants

will allow for 24/7 energy availability, with each parabolic trough CSP plant

possessing an energy storage capacity of 13.5 hours and the tower boasting up

to 15 hours.

Nitrate, the heat storage medium for the Parabolic Trough Plant-II, is stored

in eight tanks, with each one measuring 45 meters in diameter and 25,000 cubic

meters in capacity. The harsh desert environment presented a massive challenge

to the test, and labor shortages during Ramadan added another layer of

uncertainty to overall progress. The test was eventually completed on time with

the help of water trucks which transported and unloaded the water to

provisional water tanks, through which the water was pumped into the molten

salt tanks.

"I extend my appreciation to all the on-site workers for their dedication and

hard work to ensure the test was completed at speed and on time, despite the

tremendous difficulties caused by a labor shortage and local

high-temperatures," said Zhao Hui, Project Manager of Dubai CSP Project of

Shanghai Electric Power Generation Engineering Co.

"Their outstanding performance also guaranteed the smooth progress of the CSP

central tower pipeline installation, which is the core and one of the most

important parts of the structure. The space in the tower is extremely small,

given the total length of the central tower internal pipes is over 500 meters.

To make sure the work could be done on time, the project team formulated

well-thought-out installation plans and overcame all unseen problems without

causing any delay," he added.

The molten salt tank system is the answer to the challenges of thermal energy

storage. Thermal energy storage realized by molten salt systems enables power

generation on cloudy days, or long night after sunset, with high operating

efficiency and low capital costs per kilowatt-hour. During the daytime, the

molten salt is circulated to a heat exchanger from a cold tank to absorb heat

from the high-temperature oil. The heated molten salt can then be stored in an

insulated hot tank which can later send the liquid to power steam turbines at

night or during unfavourable weather conditions.

In 2018, Shanghai Electric was appointed as Engineering, Procurement and

Construction (EPC) contractor for the fourth phase of Mohammed bin Rashid Al

Maktoum Solar Park in Dubai after signing the agreement with DEWA (Dubai

Electricity and Water Authority) and ACWA Power to undertake both the 700 MW

CSP and 250 MW PV projects. Financed by China's Silk Fund and ACWA, it is a

landmark project of China's Belt and Road Initiative, as well as a significant

milestone of Shanghai Electric in participating in renewable energy utility

construction in the Middle East and its shift of focus from coal-fired energy

to renewables.

In 2021, Shanghai Electric ranks 17th in the list of top 100 international

contractors, 5th in the field of electric power engineering, according to the

latest evaluation released by the China International Contractors Association.

In addition, the Company has also been granted "A-level international

contractor", the highest rating, by the association.
