Important events
In Albania, Energji Ashta and its owners, the Austrian
utilities VERBUND and EVN, successfully commissioned
the Ashta hydropower station (consisting of
Ashta 1 and Ashta 2), which is the largest matrix
hydropower plant worldwide. ANDRITZ HYDRO
supplied the entire electromechanical equipment,
including 90 Hydromatrix units. The Hydromatrix technology
developed by ANDRITZ HYDRO is an innovative
and low-cost concept consisting of a matrix of preassembled
modules for small turbine/generator units
that can be combined flexibly for different power plant
arrangements. Ashta has a total output of 53 megawatts
and will supply 240 million kilowatt-hours of
electrical energy a year for 100,000 Albanian
households.
The Gössendorf hydropower plant, Austria, was also
commissioned successfully. The two ten megawatt
bulb turbines and 13 megavolt ampere generators supplied
by the business area have an annual electrical
energy output of 90 million kilowatt-hours, supplying a
total of 23,000 households. In addition, the business
area supplied the entire control equipment, including
automation, protection equipment, and connection to
the control center.
In Indonesia, modernization work was completed on
the Larona hydropower station. The order comprised
the delivery of two generators, including an output
increase from 65 to 85 megavolt ampere, replacement
of the runners, refurbishing of the excitation and protection
systems, as well as complete installation and
commissioning of the turbine/generator units.
At the Santo Antônio power plant, Brazil, the second
of two bulb turbines supplied by ANDRITZ HYDRO
Inepar was turned successfully for the first time. The
first of the bulb turbines was commissioned successfully
in March 2012. As part of a consortium, ANDRITZ
HYDRO Inepar will supply bulb turbines, generators,
turbine governors, and excitation systems for 12 of
the 44 machine sets as well as all the control systems
for all 44 units.
Following the rehabilitation work, three Kaplan turbines
and the electrical equipment at the Tavagnasco hydropower
plant, Italy, were commissioned under an order
from Utilizzazioni Elettro Industriali.
Two pumping stations were also commissioned for the
Bheema sub-project in Andhra Pradesh, India. The
order covered supply and installation of six pumps
for irrigation of agricultural land. The Indian state
of Andhra Pradesh is frequently hit by widespread
drought. As some 70% of the population makes a living
directly or indirectly from agriculture, the Indian government
launched the Jalayagnam project for irrigation of
all agricultural land. The ANDRITZ deliveries cover a
total of eleven sub-projects.
Important orders
Newfoundland and Labrador Hydro, Canada, ordered
the delivery, installation, and commissioning of the
electromechanical equipment for Muskrat Falls hydropower
station, comprising four 212 megawatt Kaplan
turbines, generators, and automation equipment.
As part of the new Assiut dam project, the business
area was awarded an order by the Egyptian Ministries
of Energy and Water Supply to deliver and install four
bulb turbines (eight megawatts each), generators, the
electrical equipment, and the hydromechanical equipment.
Reconstruction of this oldest dam on
the Egyptian part of the Nile will not only substantially
improve conditions for irrigation and shipping,
but also lay the foundations for generating energy from
sustainable hydropower. The four bulb turbines with
a total output of 32 megawatts will supply around
75,000 households with green energy from
2017.
ANDRITZ HYDRO is to supply three 173 megawatt
Francis turbines, three generators, and the electrical
power plant equipment for Cerro de Aguila hydropower
station, Peru.
