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.

1965 Expansion of production

to the Americas: construction of a hydro power generator factory in Sao Paulo.

• 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

Small HydroRES positioning

Positioning of RES, according to two different ratios:

• Economic/environmental (EROEI - cent € / kWh)

• Exclusively economic (cent € kWh / availability)

Ocean PowerIn the news

22/05/2013



• 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

°

22/05/2013



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
