Wind farm near Agrigento, Sicily (I)

In addition to large-scale power plants and energy efficiency, Alpiq is also stepping up investments in renewable energies: for example, in wind power projects in Italy and Bulgaria as well as the construction and operation of small hydroelectric power stations in Norway and Switzerland. Alpiq is also involved in a major research project in Germany through one of its subsidiaries.

Alpiq promotes wind energy and hydro power

Together with Alpiq EcoPower Ltd., founded at the end of 2006, Alpiq has earmarked CHF 200 million for the construction of small hydroelectric power stations in Switzerland. Several dozen projects are currently being examined. In addition, Alpiq and the Swiss Federal Railways are building the 600-MW Nant de Drance pumped storage power station in the canton of Valais.

Alpiq is also stepping up its renewable energy activities in Italy. In Sicily Alpiq has an almost 50 percent stake in the operation of two wind farms in Ramacca and Marineo respectively, and an 85 percent stake in the Gestimi and Idrovalsesia small hydroelectric power stations in the Piedmont region.

Kraftanlagen München GmbH (KAM), a subsidiary of Alpiq Group member AAT, is the general contractor responsible for planning and building the Jülich experimental power plant in Germany. This will be the first solar-heated power plant of its type in Germany and represents a milestone in the move towards CO2-free electricity generation. The investors hope that the plant will produce new findings on solar technology, which can be used to open up new sales markets.

Alpiq engages in renewable energies in these areas:

Hydroelectricity

Hydroelectricity is Switzerland's most important renewable energy source. Alpiq continually invests in the construction and operation of hydroelectricity stations and their optimal use.

Wind energy

Due to the irregular nature of wind, the electrical energy generated can only be used for the ongoing provision of electricity if combined with other energy sources or when stored in the form of water.

Solar energy

The sun's energy is converted to solar electricity using photovoltaic technology. Or solar radiation is collected and used as thermal energy using solar thermal systems. Alpiq is the technology supplier for an experimental solar thermal power plant.

Biomass

A biomass power plant generates electricity and/or district heating by burning biomass. This includes solid fuels such as wood, cereals, straw or largely organic waste. Alpiq supplies the technology for building such installations.
