24/01/2024: Synchronization ANDRITZ to supply equipment for major pumped storage project in Greece 

GRAZ/VIENNA, JANUARY 23, 2024. The Greek company TERNA S.A., construction branch of GEKTERNA Group, awarded the international technology group ANDRITZ a contract for the supply of electromechanical equipment for the new Amfilochia Pumped Storage Complex in the Central Greece region. It is the largest grid energy storage investment in Greece and a milestone project for the country’s clean energy transition. 

Once in commercial operation, the power plant will have a total installed capacity of 680 MW (generation) and 730 MW (pumping) with an estimated total production of approximately 816 GWh of clean and sustainable electrical energy per year. 

The advanced pumped storage plant will act as a green battery by balancing fluctuations in power generation from wind and solar plants, thus ensuring the secure and stable operation of the Greek power grid. 

Given the global increase in energy demand and the growing share of volatile renewable energy sources, economical solutions for storing large amounts of energy are essential. Pumped storage power plants represent the most efficient method of storing large amounts of energy for extended periods of time. They therefore play a key role in the clean energy transition. 

ANDRITZ is proud to be part of this important project and to make a significant contribution to a clean and sustainable energy future through state-of-the-art equipment and expertise. 

The ANDRITZ scope of supply includes the design, manufacture, supervision of erection, and commissioning of six reversible pump-turbine generator units, along with associated auxiliaries and ancillary equipment, governors, excitation and protection system, main inlet valves, draft tube gates as well as digital services.

22/12/2023: FNII Project U12 Successful Synchronization

On December 10, 2023, China's first variable speed unit supplied by ANDRITZ was successfully completed its first synchronization test at Fengning Pumped Storage Power Station, achieving another major milestone. 

Fengning Pumped Storage Power Station is located in Fengning, Hebei Province, consisting of two variable speed units which are the first ones in China. The main installation work of the first variable speed unit commenced in August 2022. since after, the installation has been progressing steadily. 

• Stator lifted into pit on Mar. 15, 2023  

• Rotor lifted into pit on Jul. 4, 2023 

• The main installation work completed in mid-Oct. 2023 

• Dry commissioning completed in early Nov. 2023 

• Wet commissioning officially commenced on Nov. 10, 2023 

• First run of the unit on Nov. 27, 2023 

• First synchronization test in turbine mode completed on Dec. 10, 2023. 

ANDRITZ is not only the equipment supplier for the first variable speed units in China, but also the first manufacturer in China to take the lead in organizing various parties to carry out the wet commissioning. It is natural that ANDRITZ would encounter various challenges in the process, such as commissioning test plan and procedures are hard to be drafted, no relevant experience to learn from in terms of its wet commissioning and overall on-site coordination, language and culture barriers that come with multi-national teams, unforeseen issues that occur during the wet commissioning process, and beyond.  

To address the above-mentioned challenges, ANDRITZ commenced with the plan of setting up the commissioning team in June 2022. In September 2022, ANDRITZ Fengning project commissioning team was officially established, consisting of 18 Chinese and foreign commissioning engineers, with Chinese engineer Mr. Pan Bin serving as the chief commissioning coordinator. Among these 18 members, 7 of them are senior commissioning engineers from ANDRITZ Hydro offices in Germany and Austria, and the rest are from ANDRITZ Hydro China, all of them are experienced in site commissioning. 

In March 2023, ANDRITZ began to draft the commissioning test plan and commissioning procedure. To let the foreign commissioning engineers be familiar with the system rules and requirements for commissioning work in China, Pan Bin organized internal meetings to introduce the requirements from Xinyuan Company and the client Fengning in terms of the process management, safety measures, document management, and other aspects for wet commissioning startup. As it is the first variable speed unit in China, its requirements and commissioning scope are different to ANDRITZ’s past project experience and existing document system. Therefore, the initial draft progressed very slowly at the beginning. To solve this issue, we changed our strategy. With necessary input for each system provided by foreign commissioning engineers, the commissioning coordinator integrated all information to one file. The initial draft was reviewed by the entire commissioning team before submitting to Fengning Company for official review and was submitted to the client Fengning for the first review in June 2023. After multiple rounds of communications, clarifications, and document modifications, the first draft was confirmed in August 2023, and the final version was reviewed by a panel of experts invited by the customer at the end of September 2023. On November 10, 2023, the First Variable Speed Unit Wet commissioning and Trial Operation Conference was held, announcing the official start of the wet commissioning work. 

In view of our past project experience, ANDRITZ is mainly responsible for commissioning our own supplied equipment. We barely have any experience in leading the entire power plant equipment commissioning. Nevertheless, ANDRITZ actively communicated and coordinated with our client, learned from fellow commissioning engineers from other companies, and exhausted all resources. As a result, leading by ANDRITZ, we formed a great commissioning team of 62 members from 5 companies and collaborated on-site. ANDRITZ makes sure that every task is covered, and the overall commissioning work is carried out safely and smoothly. 

To enhance communication efficiency, we have meetings on daily basis. The on-site morning meetings are to define the commissioning tasks for the day, while the on-site evening meetings report the work progress of the day and address issues. To ensure the project schedule, we adhere to the principle of “never put off”. 

After five months’ efforts, with everyone working hard day in and day out, we finally completed the synchronization test of the first unit successfully, a key milestone of the project.  We are glad that we achieved the target that our client set in mid-year. The successful synchronization is a big step forward for whole project. Furthermore, it made us more confident with the following commissioning work. None of the involved engineers has any experience in commissioning of the variable speed unit before, so the hardships in the process need not be said. Even so, with great perseverance and team spirit, we have overcome all difficulties and challenges, and achieved a phased victory in commissioning work. We are very proud of our commissioning team.

The Austrian Ambassador to China, H.E. Mr. Andreas Riecken, visited Sichuan Province from June 14 to 15, 2023 and met with provincial and municipal leaders on strengthening the cooperation.

It was the Ambassador's first visit to Sichuan since taking office in August 2021.

Accompanied by Mr. Guenther Lazelsberger, the Consul General of the Austrian Consulate in Chengdu, the Ambassador and his delegation visited ANDRITZ Chengdu Branch in the afternoon of June 14. Mr. Karl Schloegelbauer, General Manager of ANDRITZ Hydro China, and Mr. Zhang Shenglin, Manager of ANDRITZ Chengdu Branch, warmly received the Ambassador and his delegation. ANDRITZ Chengdu Branch is the turbine and generator manufacturing base for ANDRITZ Hydro China, headquartered in Austria. 

During the meeting, ANDRITZ first gave a brief introduction of the business areas of the ANDRITZ Group and its Hydro business. An overview of the development of the hydropower business in recent years and the future development trends was given. In the presentation, ANDRITZ demonstrated that several parts of the hydroelectric power generation equipment are large and heavy. Therefore, the delegation was very curious about how they are transported to the site. In this regard, ANDRITZ Hydro explained to our guests the advantages and disadvantages of the geographical location of the Chengdu workshop. Sichuan province is in the southwest of China and has a huge amount of water resources across the province. At the same time, it is relatively close to Southeast Asian countries such as Vietnam and Lao PDR, with their growing hydroelectric power demand. In the southwest, Southeast Asia can be reached through land transport, the Mekong and other river transport. To the east, the Shanghai port can be reached through the Yangtze River or by road and then further by sea. Another transport option from/to Chengdu is via railway with its connection even to Vienna, Austria (China-Europe freight trains).

Afterwards, H.E. Mr. Riecken and the delegation visited our workshop and had a field tour to get a general idea of the main components of the products being processed in the Chengdu workshop. The Ambassador and the Consul General expressed their recognition of ANDRITZ's technical expertise and manufacturing competency, expressing their hope that ANDRITZ can consolidate its position in China. The Austrian Embassy and the Consulate in China will do their best to provide support for the development of Austrian enterprises in China.

22/07 2022: Pac Ma Hydropower Project in Vietnam - First Unit Synchronized

On 6th of July in Pac Ma Hydro Power Station: the first unit (Unit 4) was successfully synchronized, and there are three more to go!

The commissioning team had achieved the first turn of unit 4 back on January 18th, 2022, but the synchronization of the first unit had been pending until July of 2022. This was due to COVID-19 impact and civil construction delay because the process of energizing of the transmission line was postponed by relevant authorities.

Although the delay of the transmission line was unexpected and the site resource were limited due to the project extension, ANDRITZ team kept pushing the site progress tightly and closely with client:

• February 2022: The last unit stator assembly was successfully completed, thus ANDRITZ was awarded with a bonus from client for the successful acceleration of four units stator assembly work. 
• End of March: The second unit (Unit 3) installation was completed and in April, it was ready for synchronization. 
• May: The third unit (Unit 1) installation was completed.
• End of May: Three milestones of the last unit (Unit 2) were achieved, the lowering of the runner hub, lowering of the bulb, and lowering of the rotor.
• June: The third units (Unit 1) dry commissioning was completed, but the wet commissioning could not proceed due to the gates’ overhaul.
• June 30th: Client got the permission of transmission line energization.
• July 3rd: Transmission line, GIS, main transformers, and station service system energized successfully. 
• July 6th: First unit (Unit 4) was successfully synchronized, and the 3-day-trial run commenced.

Meanwhile the stator and the bulb including the hatch cover of last unit (Unit 2) were installed, which means the last unit is also near completion.

We expect all four units to be put into operation within the next two months, meaning an impressive and overwhelming history-marking feat in the hydropower industry: four units in operation within only two months!

23/06 2022: Xekaman 3, Laos - Successful Completion of Two Units

The Xekaman 3 hydropower project is a refurbishment project which suffered serious overflooding on plant site after a 5-year operation.

Combined investigation results with optimized refurbishment methods, extraordinary effort, and top tier technology the ANDRITZ team could overcome numerous hinderances and problems and finally successfully execute the execution of both units of this hydropower plant on the Nam Pagnou River, which is highly commended by the client. 

Besides the COVID pandemic and lockdowns, limitation of transportation, and shortages of supplies, one of the biggest challenges were that the powerhouse foundation was found going tapper 0.08 mm/ meter. This was rectified by the ANDRITZ site team while guiding erection and installation which resulted in no vibrations and no need of balancing the units during commissioning.

The refurbishment contract was split into two parts. The first contract for the main turbine, generator and MIV, the second contract for automation, electrical equipment, and for service of guiding the assembly, installation and the complete commissioning.

With maximum personal commitment from the ANDRITZ teams on-site, the clients’ goal to reach power generation as soon as possible was supported: unit 1 put was put into operation on May 18th, 2022, unit 2 on May 30th, 2022, one and half month ahead of the contract date. The completion certificates of the two units after the 72-hours trail run have been received.

We are very proud of the teams and their personal commitment on executing the project under such tough circumstances and living conditions.

Site Manager and Turbine supervisor Mr. Xie Qiang: 

At 5:40 PM on May 30th, with a burst of applause in the central control room, U2 officially entered 72-hours trial operation, so far realized the dual machine full load operation, my heart was full of pride and joy, but also instantly felt the release of a lot of fatigue and pressure. Although I have been working on the project site for more than 9 months continuously, I still had to face the risk of the epidemic and the difficult living conditions, but I have overcome these difficulties and insisted on doing the work well. Now I feel that all the efforts are worth it, which makes me stronger and gain more experience.

As a SM, I am not so rich in experience yet, and the challenges have been polishing my skills along the way. During this process, I am very grateful for the support and understanding of the whole project team for my work, especially for the trust in me from the management and giving me this rare opportunity to challenge and improve myself.

Test team leader and EPS EV&CE Mr. Han Xiaoyi: 

I will be retiring with October this year. Now, I can say the success of project Xekaman 3 completes my career. I’m so delighted to work with the young team and share my experience with them, and they keep me energized at the same time.

AT SE and Control CE Mr. Lin Zhenhua: 
I am mostly driven by my eagerness to reunite with my family as I have a new-born. I am happy my hard work paid off, and the task is done ahead of time, so I can go home earlier with a light heart.

Protection CE Mr. Li Gang:

We can always create magic!

Generator SV&CE Mr. Padmanaban: 

We did it! Even the foundation was inclined, we rectified and balanced it during installation, the result reached as vibration is very lower even from first start. Amazing. But six days a week, 10 hours a day, working at site (without any local holidays) is very tough to the body, I survived, but it is not advisable.

Governor CE Mr. Imsan: 

I’m from Andritz Indonesia. I jumped from the Nam Tehun1 project site to Xekaman 3 site, and I found it is very easy to carry out my duty with the support from Chinese and Indian and Vietnamese colleagues. A successful example of “One ANDRITZ”!

March 2022: Thac Ca 1, Vietnam – Successful completion of project in difficult circumstances

On 22nd of February 2022, the Preliminary Acceptance Certificate (PAC) for Thac Ca 1 HPP was granted by the project owner and the power plant started officially commercial operation.

Since the commencement of the project, the COVID-19 pandemic, earthquake, and the complex geologic structure have made the construction on site more difficult and forced the client to do some additional investments. To obtain an additional loan from the Bank, the client promised to run the first unit of the power station on 18th of January 2022, as a token to demonstrate their loan repayment capacity. Bank representatives have witnessed the first run as well.

However, when the client made the agreement with the bank, the actual site situation was dire, as the dry commissioning of unit was completed end of December 2021, and most ANDRITZ test engineers moved to another project site. Moreover, the water storage was not done due to the spillway gates installation being delayed. 

Nevertheless, our client’s target is ANDRITZ’s target. ANDRITZ is always anxious about what our clients anxious about, and fully responds to their needs.

The COVID-19 pandemic caused many travel restrictions, and this made it harder for ANDRITZ to dispatch enough test engineers to the site in time, but our commissioning coordinator Mr. Pan Bin and site manager Mr. Peter Foessl have managed to run the unit with the personnel available. This is the first time we have started to run a unit under such tough circumstances (only with control test engineer, generator test engineer and installation supervisors available). On all accounts, all's well that ends well. We finally started the unit at 21:35 p.m. and reached 30% of rated speed at 22:30 p.m. on 18th January 2022. The client was satisfied with the result and the milestone was reached successfully.

With joint efforts, our client delivered on the promise to the Bank and kept the project advancing smoothly.

Our site engineers didn’t even have time to enjoy the moment of this achievement, as they were on their way to next project site. 

We would like to express our gratitude to all HYDRO China colleagues who are still working on our overseas project sites currently.

ANDRITZ Hydro and MAN Energy Solutions agree on hydrogen cooperation

International technology Group ANDRITZ and the German company MAN Energy Solutions have concluded a strategic framework agreement to jointly develop international projects for the production of green hydrogen from hydropower.
 

Frank Mette, CEO of ANDRITZ Hydro in Germany, and Dr. Uwe Lauber, Chief Executive Officer and Chief Technology Officer of MAN Energy Solutions, signed the agreement in Ravensburg.

A pilot project in Europe will mark the start of the collaboration. Subsequently, the companies want to jointly identify further projects and implement them in the context of the German Federal Government's H2 Global initiative. H2 Global is a market-based funding platform, which aims to efficiently promote the market launch of green hydrogen and hydrogen-based power-to-X products. For this purpose, hydrogen energy partnerships are to be established with countries with a correspondingly high potential to provide a long-term, cost-effective, and reliable green hydrogen supply to Germany and the EU.

Frank Mette: “Hydropower is one of the few completely climate-neutral forms of energy, which is capable of providing base load power. We therefore see excellent potential for worldwide expansion – in new construction projects just as much as in repowering. By adding the possibility of producing hydrogen to hydropower plants, we are taking the next step and also making the energy generated there ready for export and storage without restriction. Together with MAN Energy Solutions, we can open up new markets and opportunities for the operators.”

Uwe Lauber: “The economy of the future will be climate-neutral, and to achieve this it needs huge quantities of green hydrogen. Together with ANDRITZ Hydro, we want to make this resource available. Hydropower plants are ideal for generating hydrogen in a completely climate-neutral, reliable and cost-effective manner. With ANDRITZ Hydro, we have been able to enter into a partnership with a world leader in the field of hydraulic power generation, to develop these prospects together with us.”

The companies are aiming to launch an initial joint pilot project before the end of this year, to provide about 650 tons of green hydrogen by using an electrolysis output of up to 4 MW, initially for local use. In follow-up projects, designed for the export of hydrogen, the installed electrolysis output is expected to increase to up to 100 MW in the coming years.

Frank Mette: “MAN Energy Solutions contributes scalable and, above all, flexible electrolysis technology to this partnership, along with many years of experience in power-to-X technology and plant engineering. Together, we will tap growth markets for hydrogen in Europe and worldwide, including for the production of green hydrogen, which can then be imported by German consumers.”
