MILLARES II
The Most Important Project in Spain Commissioned in 2002, for the Most Important
Spanish Hydro Utility - IBERDROLA
Millares II hydropower plant was
recently successfully finalized
and commissioned in the summer
of 2002.
The most important hydroelectric
project carried out in Spain in the
past years, Millares II was built by
Iberdrola in the eastern region of
Spain, province of Valencia. Iberdrola
is one of the Global Key Accounts
of the VA TECH group, not
only for its importance as the leading
utility in the hydro electrical field
in Spain and also in Europe, with
50% of the installed power in hydro,
but also as an active investor
abroad, especially in Latin America.
Their 8,000 MW installed power
(200 stations, 400 units) represent
50% of the total installed hydro capacity
in Spain and 10% of the total
in the European Union.
VA TECH HYDRO in Madrid has
been a traditional supplier of Iberdrola
for years, for new plants and
service work, always keeping an excellent
relationship with this client
and having collaborated in many
other important projects in the past.
As a result of Iberdrola´s confidence
in the reliability of our company,
VA TECH HYDRO was awarded a
10
KEY PROJECTS
contract for the supply of all
electromechanical equipment for
Millares II including:
• 2 vertical Francis turbines
• 2 butterfly valves
• 2 governor systems
• 2 downstream gates
• 2 penstocks ( Ø 2,500 mm )
VA TECH HYDRO in Spain provided
the entire engineering for this scope
of supply and the turbines were
completely manufactured at the
workshop in Madrid, with excellent
results in all shop tests carried out
by the inspection service teams from
Iberdrola. The two penstock linings,
with vertical portion, elbows, transition
pieces and conical sections
and the downstream gates were designed
by VA TECH HYDRO in Spain
and then approved by Iberdrola Engineering
and manufactured by in
subsuppliers at their workshops with
quality control inspection by us. The
butterfly valves were also designed,
manufactured and shop tested by
VA TECH HYDRO in Spain. They
have a special double seal system
(service and maintenance seal) as
requested by the client.
Finally, VA TECH was responsible for
the supervision of site installation
and the final commissioning of all
equipment, successfully completed
in the summer of 2002.
