Renewables are the future
innogy has taken on the task of proactively shaping and leading the energy transition. We have been producing green energy from water, wind, sun and biomass for years at various locations throughout Europe.
„Renewables are the growth drivers at innogy.“Hans Bünting, COO innogy Renewables
Growing market for solar power
Interest in solar energy is rising
In Germany over 1.6 million photovoltaic modules were installed in 2017, which already covered 7.2 percent of the electricity demand. Photovoltaic power has the greatest growth potential among renewable energies – after all, the sun shines everywhere.
The world’s largest onshore wind farm
Zuidwester Wind Farm is one of the most powerful plants of its kind
Zuidwester in the west of the Netherlands is a wind farm of superlatives. This farm directly on the Ijsselmeer, which innogy completed at the beginning of 2017, boasts the largest onshore facilities in the world at present. Each one of the 12 turbines replaces 50 turbines from the eighties. The new turbines are not only more efficient, but also significantly quieter than the older ones. The crucial factor: limited ground resources are utilised more efficiently due to the large scale, since the wind conditions are better higher up. At the top, a strong breeze blows for over 3,500 hours per year. The total capacity of the farm is 90 megawatts, which is equivalent to the amount needed to supply 80,000 households with green electricity for a year.
Better results with fewer turbines
One Zuidwester wind turbine with a generation capacity of 7,500 kW could theoretically supply up to 7,500 households with electricity for a whole year.
A single Zuidwester wind turbine delivers the same performance as 50 turbines built in the eighties.
The hub of a Zuidwester wind turbine is 135 m off the ground, almost the same height as the steeples on the Cologne cathedral. Including the rotor blades, the turbine reaches a height of around 200 m.
The diameter of the rotor of a Zuidwester wind turbine is 127 m, equivalent to the surface area of 1.5 football fields.
At a height of 135 m, the Zuidwester wind turbine supports a hub with a weight of 350 t – which is equivalent to 10 trucks.
