Foreword
• Since over 100 years Siemens is active
world-wide in developing technologies
on water
• In February 2012 Siemens acquired
Marine Current Turbines (MCT), a UK
company established in 1999, the world
leader in marine current and tidal energy

leader in marine current and tidal energy
to electricity conversion
• In Italy Siemens in active as EPC
contractor for small-hydro plants (SH),
thanks to the market revitalization on the
base of national law’s changes
• Let’s dive into our solutions
Siemens competenceMore than 100 years in Hydro Power
1847 Werner
von Siemens founds the company.
1866 The discovery of the
dynamo-electric principle and
1876 The Craigside house in
Northumberland, UK, was the first house lit by hydroelectricity. The dynamo was a Siemens series wound, bipolar horizontal pattern with a drum armature and
1925 Siemens wins a contract from the
Irish Free State to electrify the entire country. The core of the system is the Shannon hydro power plant.
1968 Siemens is located
in more than 100 coutries.
2008 SeaGen has been
installed in Strangford Lough.

• Integrated package of solutions for new plants, as well as plant’s revitalization and
modernization (revamping)
Small HydroRES Status in Italy
• The Italian GDP closed at - 2.0 % in 2012
with a forecast of - 1.1 % in 2013 and - 0,5 %
in 2014
• To react to the contraction’s phase of the
domestic demands, Italian companies
adopted structural changes and focus on

adopted structural changes and focus on
green investments (i.e. with FiT schemes)
• Within the Renewable Energy Sources
(RES), the PV market collapsed, meanwhile
Wind, Biomass and Hydro are still sustained
by the national FiT: in particular the SH
business is governed by the recent law DM of
July 6th, introducing a register concept

Positioning of RES, according to two different ratios:
• Economic/environmental (EROEI - cent € / kWh)
• Exclusively economic (cent € kWh / availability)

• In the longterm, tidal and wave energy must be cost-competitive with other forms of renewables, inparticular offshore wind
• Experts anticipate double-digit growth rates for the ocean power business up to 2020
• Potential good sites for this technology are coastal regions with strong tidal currents similar to those in theUK, which can also be found in Canada, France and East Asia

Ocean PowerMCTs "SeaGen"
• Rated Power Output – 1.2 MW (2x600 kW) at
2.4m/s
• Power to grid – up to 6,000 MWh/year
• Twin axial flow rotors of 16mt in diameter with
a tip speed of 12m/s
• The rotor blades can be pitched to
°

180°allowing them to operate efficiently in both
flow directions – on ebb and flood tides
• Flooded blades to avoid pressure differences
and therefore oscillating forces on their
structure
• For simplification of maintenance the turbines
are mounted on a crossbeam, which is liftable
above sea level
