Latest Vietnam Nam Na 1 ANDRITZ HYDRO has received an order from Hung Hai News Group of companies for the supply, supervision, and commis- sioning of the electro-mechanical equipment for the Nam Na 1 hydropower plant in Vietnam. The hydropower plant is located on the Nam Na River, in the Lai Chau Province. With an installed capacity of 30 MW it will supply an annual average of 134 GWh of renewable energy to Fiji the national grid. The hydropower plant is scheduled to be put Wailoa into commercial operation in 2018. ANDRITZ HYDRO has received a further order for the replace- ment of three spherical valves at the Wailoa hydropower plant in Fiji, supplying up to 80 MW to the 150 MW grid on the main Fijian island of Viti Levu. The order was placed by the Fijian Electricity Authority. A previously ordered main inlet valve also manufactured by ANDRITZ HYDRO was already installed with a station outage of only four days in 2016. Costa Rica Rio Macho In December 2016, with the Final Acceptance Certificate (FAC) for unit five, Instituto Costarricense de Electricidad (ICE) completed the good collaboration with ANDRITZ HYDRO Germany during the Rio Macho project in Costa Rica.

Dismantling and reassembling of the second machine will start in the sec- ond quarter of 2017 and should be completed until end of 2017. With an output of 2 × 94 MVA, Langenprozelten is Deutsche Bahn’s primary peak-load power plant, providing sufficient electrical energy to sustain 50 InterCity trains travelling at 200 km/h. An article with detailed information about the refurbishment of the first machine was published in Hydro News 29.
5 Latest News HYDRONEWS No. 30 DR Congo Mwadingusha ANDRITZ HYDRO has been awarded in a consortium a con- tract for the refurbishment of the existing Mwadingusha hydro- power plant in the Katanga Province, DR Congo. The hydro- power plant is equipped with six Francis units with a capacity of 11.8 MW each. The scope of supply for ANDRITZ HYDRO comprises re- placement of four turbine units, generators, governors, inlet valves, exciters, voltage regulations, and draft tube stop logs including dismantling, erection, and commissioning. Angola Laúca After two years of work, the rotor of unit #1 at the Laúca hydro- power plant in Angola has been successfully installed. This large project on the Kwanza River consists of two machine halls, for which ANDRITZ HYDRO is supplying elec- tromechanical equipment for six 340 MW Francis turbines in- cluding generators, transformers, control and protection sys- tems as well as auxiliary equipment. Rwanda Rusumo Falls In November 2016, ANDRITZ HYDRO signed a contract for design, supply, installation, and commissioning of electro- mechanical equipment for the Rusumo Falls Hydroelectric Project with Rusumo Power Company Ltd. The new power station will be located at the border between Rwanda and Tanzania. The project is a joint development of three east © Rune Freyer African nations Burundi, Rwanda and Tanzania. ANDRITZ HYDRO’s scope of supply comprises the deliv- ery of three 27,5 MW vertical Kaplan turbines and its auxilia- ries, generators, EPS, powerhouse cranes, draft tube gates and stop logs as well as the control and protection system of Uganda the whole power plant. Completion of the project is planned Nkusi for the end of 2019. In November 2016, ANDRITZ HYDRO received a contract for the complete electro-mechanical equipment for the new 9.6 MW Nkusi hydropower plant in Uganda. The customer requested a complete “from water-to-wire” package to ensure a high quality delivery with minimal in- terphases and simplified logistics. The scope of supply for ANDRITZ HYDRO consists of engineering, two identical hor- izontal Francis turbines, generators, and all equipment and installation up to the 33 kV switchgear. Transportation up to Nkusi site, supervision of installation, and commissioning complete the contractual scope of supply. The HPP Nkusi project should be completed mid-2018.

The order for the project was awarded to ANDRITZ HYDRO in 2011 by Darenhes Enerji Üretim A.Ş. – together with a con- tract for HPP Tatar, which started com- mercial operation in 2014 (see Hydro News 25).

22 Interview HYDRONEWS No. 30 INTERVIEW Santo Antônio An Amazonian Example of Sustainable Hydropower Brazil – Recently completed, the 3,568 MW Santo Antônio hydropower plant is one of the five largest hydroelectric stations in Brazil and supplies energy to some 44 mil- lion people from its 50 units. Antônio de Pádua Bemfica Guimarães is technical director of Santo Antônio Energia (SAE), a company responsible for implemen tation of Santo Antônio, he talked to Hydro News about the project. World’s largest bulb turbine being installed at Santo Antônio
23 Interview HYDRONEWS No. 30 “ An evaluation made by the International Hydropower Association (IHA), considered ” Santo Antônio the most sustainable project evaluated by them in the world. – Antônio de Pádua Bemfica Guimarães What makes the bulb turbines at HPP Santo Antônio special? HPP Santo Antônio uses the largest bulb turbines in the world. The previous record-holder uses machines rated at 68 MW, our turbines have 71.6 MW. In terms of size, at 7,500 mm diame- ter they are second only to the 8,410 mm units installed at HPP Murray Lock, in the USA. The decision to use bulb turbines was driven by the flow char- acteristics of the Madeira River and the necessity to minimize the environmental impact of a large project, significantly reduc- ing the area of the reservoir. Precisely because it is a run-of-river power plant, the bulb turbine proved the best solution to com- bine lowest impacts with highest use of the hydroelectric poten- tial of the river. What were your main considerations in selecting the key contractors for Santo Antônio? Due to the project complexity, a lot of equipment involved, and the size of the turbine set for the Santo Antônio hydropower plant, the supply chain was concentrated in the most experi- enced and largest power generation equipment manufacturers. In addition, the Santo Antônio project implementation is under an EPC (Engineering Procurement and Construction) contract structure. ANDRITZ HYDRO is part of the Santo Antônio Constructor Consortium (CCSA). Its scope of supply included 14 bulb tur- bines, 13 generators, 28 excitation systems, 26 generator switch gear systems, and three power transformers rated at 13.8 kV–500 kV. The companies that make up the CCSA had, in addition to their expertise, an important role in the development of local companies and service providers. This partnership is leaving an important legacy because they prepared local companies to meet the demands of other projects.

In total, 28 programs have been conducted and add great results. Machine hall Regarding social and environmental concerns in the country, the Santo Antônio hydropower plant is a good example for im- plementation of sustainable power generation models. Strictly respecting the rules established by the Brazilian environmental agencies, the project was designed to respect the natural char- acteristics of Amazonia, at the same time taking the maximum advantage of the Madeira’s hydraulic potential. An evaluation made by the IHA – International Hydropower Association, considered Santo Antônio the most sustainable project evaluated by them in the world, achieving the highest number of top marks in more than 20 topics related to environ- mental issues and stakeholders influenced by the project.
25 Interview HYDRONEWS No. 30 Powerhouse and dam area How do you see future hydropower development in the Amazon region of Brazil unfolding? The Amazon is the last frontier of the country's hydropower generation development, with about 70% of its potential yet to be explored. Given this, it is natural that there is a strate- gic interest in making the region an important hub of clean and renewable power generation, attracting large projects. Today, ABOUT using the Santo Antônio hydropower plant as an example, you realize that you can explore all this power responsibly, incorpo- rating the new project mechanisms that significantly reduce the environmental impact and ensure the use of the Amazon’s po- tential. The implementation of Santo Antônio is an important benchmark for other projects planned for the region, especially in breaking the old paradigm. It is possible to generate energy from the Amazon with sustainability. Joining knowledge and the sum of the technical experience of the team of Santo Antônio Energia, ANDRITZ HYDRO and other manufacturers, we are certainly making history in the Antônio de Pádua Bemfica Guimar ães implementation of large infrastructure projects, and helping to is technical director of the Santo avoid imperfections in future projects.
