The data is in, and 2013 went out with a bang as wind energy output soared to new records across Europe. Electricity prices and air pollution dropped as wind energy drastically reduced fossil fuel use during high winter energy demand. Ireland, Denmark, Spain, Portugal, Germany, and the UK all saw noteworthy wind output records broken with no electric reliability problems. Below, we summarize the news that has just broken.
Ireland
The Emerald Isle is now green for two additional reasons, as wind energy reduced pollution and protected consumers’ pocketbooks from near-record natural gas prices by providing 24% of Ireland’s electricity for all of December. The Irish Examiner noted on Monday that “The sustained wind volumes forced expensive gas powered plants off the system and this provided downward pressure on wholesale prices.” It quotes an energy trader noting that “The substantial contribution of wind energy helped reduce the monthly average wholesale electricity price by 5%.” The article further explains that wind energy played a critical role in driving the price of electricity down despite near-record natural gas prices. At times wind energy has reliably provided 50% of the electricity in Ireland, which is particularly impressive for an island power system without the advantage of large power lines to import and export power to neighboring power systems. On December 5, the output from the country’s wind turbines peaked at a record 1588 MW, and another new record of 1769 MW was set at 6:30 PM on December 17.
Denmark
Long a leader in wind energy use, Denmark’s wind energy set a new record by providing a staggering 54.8% of the country’s electricity consumption for the month of December, as reported yesterday by the Wall Street Journal’s Market Watch. For all of 2013, wind energy provided around 33% of Denmark’s electricity. On certain days, such as December 21, wind energy generated more than 100% of the country’s electricity use, with the remainder exported across Denmark’s strong transmission links to neighboring countries.
Spain
Electric sector carbon dioxide emissions plummeted more than 23% in 2013 as wind energy grew to be Spain’s largest source of electricity, as noted last week in The Guardian. Wind energy provided 21.1% of Spain’s electricity for the year, beating out all other fuel sources to provide the largest piece of the country’s electricity mix. Wind drove the dramatic drop in CO2 emissions as natural gas power plant output dropped by 34.2% from 2012 and coal-fired generation fell by 27.3%, even though overall electricity use was relatively flat at a 2.1% decline.
As we and others have explained previously, wind has been the dominant factor driving Europe’s carbon emissions downward. Even though coal use continues to declineacross Europe, that hasn’t stopped fossil fuelindustry groups, as well as somewhoshould know better, from fabricating the myth of a coal resurgence by misleadingly exaggerating the completion of a few coal plants that were begun nearly a decade ago and a temporary blip in carbon emissions as Germany shut down its nuclear fleet.
Portugal
Portugal generated over 70% of its power from renewables during the first quarter of 2013, driven by a surge in wind and hydro power output. At times, Portugal has reliably produced more than 90% of its electricity from wind. Shockingly, we still hear fossil fuel-funded groups and other naysayers in the U.S. claim that it is not practical to reliably or efficiently exceed 10% (or some other made up number) wind energy on the power system. With glaring counterfactuals in many European countries and now many parts of the U.S., it is becoming increasingly hard for them to keep their heads buried in the sand.
Germany
Germany’s old wind generation record was blown away on December 6, as wind-generated electricity peaked at slightly more than 26,000 MW. A news article explains: “The effect on [electricity] prices was also remarkable. In day-ahead trading, power prices on the exchange in Germany were only half of the levels in France and Switzerland, resulting in a large amount of power exports … Perhaps the most interesting thing about the storm in terms of wind power is that it shows how much more wind power capacity we can withstand. The record peak was still not even one third of peak demand at the time, suggesting that Germany might be able to have three times the current level of wind power–100 GW–installed before large amounts of wind power would have to be stored.” On December 24, German wind energy output came close to setting a new record.
The United Kingdom
We have previously reported that Britain set a new wind record of 6,053 MW on the morning of December 2, providing about 14 percent of the electricity on the U.K. system, according to Bloomberg News. The article said nearly 7,900 MW of gas-fired generation was shut down during the period of high wind, explaining that “wind and solar have no fuel costs, generally making them cheaper than coal or gas” and quoting an analyst that “it has given the chance for less efficient gas-burn facilities to drop output.”
A Business Green article this week provides additional updates on other wind records that were set in December.
“The facts speak for themselves – National Grid’s records tumbled one after another. Over the course of the week which began on Monday 16th December, wind generated a record 783,886 MWh – the highest ever for a seven-day period – providing 13 per cent of Britain’s total electricity needs that week.
On the Saturday before Christmas – a busy day for everyone and one when demand for electricity is high – we saw a record daily amount of power produced from wind with 132,812 MWh generated; a staggering 17 per cent of the nation’s total electricity consumption that day. Don’t forget that every unit of clean electricity generated by wind means one less unit is generated using expensive imports of polluting fossil fuels, so this represents a significant economic and environmental benefit for all of us.
The good news is, in fact, even better when we consider that the smaller wind farms that feed into local networks where the output isn’t recorded by National Grid would make the above figures at least 30 per cent higher.
The record-breaking trend has continued into the New Year with the highest half-hour contribution from wind on the transmission system having been achieved on the 6th January.”
