Last week it was announced by industry trade body RenewableUK that the month of December 2013 had seen several wind power records being broken. The announcement followed the publication of electricity generation statistics for December by the National Grid. Despite the high-winds experienced in the UK over the course of December it should be noted that the setting of new records does not simply represent a particularly blustery month but rather the continuation of an upwards trend.
The first record which was broken was the amount of wind power generated in a single month. December saw 2,481,080 MWh (Megawatt hours) of electricity being generated from wind power. This level of generation is enough to power 5.7 million British homes at a time of year which traditionally sees an increase in power usage and demand. The previous record was set in October 2013 when 1,956,437 MWh of electricity was generated from the wind. Crucially, however, this increase in generation led to an increase in the use of wind power by the UK. In December 2013 10% of the UK’s total power demand was sourced from wind power. In comparison, October 2013 saw 8% of the UK’s total energy demand being sourced from wind.
Records were also broken for the amount of electricity generated from wind power over the course of a single week and a single day. The week beginning Monday the 16th of December saw 783,886 MWh of electricity being produced from wind power. This level of power generation represented 13% of the weeks total electricity demand. The 21st of December was the day on which the single day generation record was broken. 132,812 MWh of electricty was generated from wind power representing a notable 17% of the days total electricity demand. The single day generation record had set as recently as the 29th of November. The regularity with which new records are being set reveals the progress that the UK’s wind industry is making in increasing capacity and reducing the country’s dependence upon fossil fuel imports. Indeed around 500 Megawatts of new wind capacity was installed and connected into the National Grid between June and November 2013.
Maf Smith, Deputy Chief Executive of RenewableUK made the following statement whilst announcing the new records:
“This is a towering achievement for the British wind energy industry. It provides cast-iron proof that the direction of travel away from dirty fossil fuels to clean renewable sources is unstoppable.
“In December, we generated more electricity from wind for British homes and businesses than during any other month on record – and we also hit weekly and daily highs.
“This gives us a great sense of confidence for the year ahead, when we will continue to increase the amount of clean power we generate from wind, onshore and offshore.
“As we do so, we are lessening our dependence on excruciatingly expensive imports of fossil fuels which have driven people’s fuel bills up. British wind energy is providing a better alternative – a stable, secure, cost-effective supply of home-grown power”.
Of course it should be remembered that the figures released by the National Grid do not represent the full amount of wind energy being generated in the UK. There are a large amount of wind turbines in the UK, particularly within the small to medium scale (the scale at which we at Intelligent Land Investments (Renewable Energy) specialise in) which do not feed power into the National Grid. Such turbines will be supplying power locally or on-site. The owners of such developments are not required to supply real time output data to the National Grid and as such will not have been included in their figures.
It should be noted that UK wind power breaking such records as this is set to become a regular occurrence in the near future as more turbines are consented, constructed and begin to supply power into the National Grid. We at Intelligent Land Investments (Renewable Energy) are looking forward to playing our part in this process as more of our developments are completed in the very near future.
In other news, figures released by Spain’s national grid operator have revealed that wind power has become the country’s dominant electricty source in 2013. Red Electrica de Espana (REE) published a report which revealed that for the very first time wind power contributed more to meeting electricty demand within the country than any other source. Over the course of 2013 wind met 21.1% of Spanish electricity demand. This was enough to produce more than Spain’s fleet of nuclear plants which met 21%. In total 53,926 GWh (Gigawatt hours) of electricity was produced from wind power in 2013. This represents an increase of 12% over 2012.
It should be noted that other forms of renewable energy also saw an increase in their output. Hydropower generation soared to 32,205 GWh; a 16% increase on the historic average helped by high levels of rainfall. Solar energy also contributed more due an increase in capacity. In 2013 173 MW of new wind power capacity was introduced into the grid, 140 MW of solar PV and 300 MW of solar thermal capacity were also added to the system. These increases mean that renewable technologies now account for 49.1% of installed Spanish capacity.
The success of the Spanish embrace of renewable power can also be seen in the reduced output of more traditional forms of electricity generation. Output from traditional gas fired power plants dropped a dramatic 34.2%. Output from coal fired plants dropped 27.3% and even nuclear output dropped by 8.3%. These reductions combined with a 2.1% drop in total power demand and increased use of renewable power has meant that the greenhouse gas emissions produced by the Spanish power sector are estimated to have dropped an incredible 23.1% last year to 61.4 million tonnes. These figures demonstrate that an electricity supply system based upon renewables not only works for end users but also serves to increase energy security and reduce carbon emissions.
We at Intelligent Land Investments (Renewable Energy) are delighted to have played a part in setting new wind generation records. We also look forward to helping set new records with our already installed turbines and also those of our developments which will have completed construction in the near future.
