Renewable energy for Europe
As a renewable energy company we aim to lead the way by being open and transparent. In our interactive site map we pulled together the most important data of all Innogy assets in operation. Move over sites for more information like the location, installed capacity or the commissioning of the asset.
Please use our interactive click map. Production data from many renewable energy power plants can be called up on our interactive map. You will find wind farms, hydro power plants as well as biomass CHP plants with the live production data, which will be updated every minute. Move over sites on the map to show the live production data in kilowatts and further information like the location, installed capacity and commissioning date of the asset. Whilst the live production data is not yet available for all sites, most of the hydro plants in Germany and the United Kingdom are already covered and the map is being continuously extended.
Generation figures of wind farms – putting it into context
As a responsible and open renewable energy developer RWE provides live updates on the power our projects generate. Whilst the figures provide a momentary ‘snap-shot’ of information it is important to understand the background context of the information.
Brian Allen is head of Engineering and Technology at RWE npower renewables. His team are responsible for supplying technical support throughout the wind farm life cycle, from development through construction, operation and eventually decommissioning.
In this short interview Brian provides talks about generation figures and why they can sometimes fluctuate
Why do the generation figures for onshore wind farms fluctuate?
Whilst wind is a sustainable energy resource it is variable depending on the how windy it is. So for example during periods of low wind speed (predominantly in the summer months) generation figures may be lower than average. However most wind turbines will generate clean energy in the region of 80-85% of the time.
Do low wind speeds times correlate with how much energy is being used by households?
Periods of low wind speed can have some correlation to seasonal demand. So for example August is generally a low wind speed month but equally energy consumption is generally low in the UK that month.
I’ve read that some wind farms take energy from the grid - so show a minus generation figure. Surely wind farms are supposed to put energy into the grid?
As mentioned before most wind turbines will generate clean energy in the region of 80-85% of the time. Occasionally in low wind conditions the turbines will create very little or no generation. When any power plant is not generating it tends to consume electricity. These are small amounts of consumption, a few kW per turbine, and in comparison to monthly energy output are less than 0.5% even in the summer. The consumed electricity is paid for by the wind farm owner at market rates.
It’s important to take account of the overall picture. The latest Government figures show that in 2012, more than 11% of the UK’s electricity came from renewable sources, with wind providing the lion’s share. The amount of clean electricity generated in the UK from renewables is increasing all the time – it grew by 20% last year. Going forward wind power will form a core part of the UK’s generation mix allowing our nation to fulfil its obligation for cutting CO2 emissions. The debate on our energy mix should not be an either / or one, we have three distinct issues that should be addressed CO2 reduction, security of supply and consumer cost. No one generation type will meet these entirely hence a mix of technologies is preferable.
