World’s biggest wind energy event kicks off in Hamburg

The world’s biggest wind energy event, the Global Wind Summit, begins today in Hamburg. The event will be held from September 25th to September 28th, 2018. Under the theme “Breaking new ground” the event will show wind energy is starting to evolve rapidly in terms of costs, technology and where it’s being deployed – and how it’s beginning to look beyond the electricity sector at how it can help decarbonize the rest of the energy system. The Global Wind Summit – consisting of the WindEnergy Hamburg expo and the WindEurope Conference – will bring together more than 1,400 exhibitors, 500 speakers and presenters and a star line-up of energy ministers and CEOs from around the world. Also taking part are EU Commissioner Miguel Arias Cañete, IEA Executive Director Fatih Birol, and the Director General of BusinessEurope, Markus Beyrer.

“Wind has a critical role to play in the world’s energy mix. It already accounts for almost 5% of electricity generation today, but its potential is much greater. With ongoing cost declines and the right government policies, it could become a leading source of generation globally in the coming decades,” explained Fatih Birol, Executive Director of the International Energy Agency at the Global Wind Summit on Tuesday.

Throughout the course of this week, the world´s largest wind industry event will highlight of one of the world’s most innovation-driven sectors. The wind industry is now a dynamic global force – creating jobs, transforming local economies and decarbonizing the world’s energy mix. The Global Wind Summit will build on the pioneering achievements of the industry and set the agenda for the further evolution of wind energy and the contribution it makes to society.

World’s biggest wind energy event kicks off in Hamburg

GERMANY: The Federal Network Agency (BNA) has launched its second joint tender for 200MW of wind power and solar PV.

wind-solar tender launched

A price ceiling of €87.50/MWh has been set in the auction, which will be concluded on 2 November.

The two technologies will compete directly against one another for the lowest cost of electricity, the agency confirmed.

In Germany’s first joint tender, carried out in April, the entire 200MW capacity was allocated to solar PV projects, with contracts awarded with values ranging between €39.60/MWh and €57.60/MWh.

Both solar and wind projects must be at least 750kW, according to auction rules.

Most solar projects are capped at 10MW, but may be 20MW in "some districts", the BNA stated, while no such limit is mentioned for onshore wind farms. Federal Immission Control approvals must have been issued for wind projects three weeks before the bid date (11 October). All participants must also factor in the cost of network and system integration into their bids.

Germany’s Renewable Energy Act (EEG) requires two joint onshore wind and solar auctions per year between 2018 and 2021.

This pilot phase will then be evaluated before the government decides whether to continue with the joint tenders beyond 2021. The heads of the Federal Solar Industry Association (BSW-Solar) and the German Wind Energy Association (BWE) described the joint tender process as "unsuitable" for encouraging the build-out of the two technologies, following the auction in April.

UK Wind Sector Defends Placid Summer Performance

Press decries “dirty summer” despite higher-than-ever installed wind capacity.

UK Wind Sector performance

The U.K.’s wind industry is cautiously responding to data showing poor project performance during a balmy summer.
Luke Clark, head of external affairs at the wind industry body RenewableUK, said his organization is awaiting official second-quarter energy figures, due out Sept. 27, before declaring an official position on news articles published last month.

The Guardian, for example, reported that calm, sunny weather had seen wind’s share of summer electricity generation dropping to 10.4 percent from 12.9 percent a year ago, forcing gas turbines to step into the breach. “This year has seen a comparatively dirty summer for power generation, due to the weather’s impact on renewables,” said the paper. “The wind drought meant that at times turbine blades sat idle for days.”

But despite an increase in carbon emissions compared to 2017, this summer was still the second greenest on record for the U.K. electricity system, according to the paper. In August an energy consultancy called EnAppSys claimed fossil-fuel generation had fallen to its lowest single-month level ever since World War II. Because of this, Clark said: “It’s important to look at wind performance over a meaningful period of time, rather than focusing on shorter spells.” In the first quarter of the year, he said, wind power had generated 19.1 percent of the country’s electricity. Annually, it is expected to contribute half of the 30 percent of electricity supply that comes from renewables, he noted. Wind, above all, was the driving force that helped the U.K. repeatedly smash coal-free generation records earlier this year. It even had a hand in helping the U.K. get through a headline-grabbing series of cold snaps dubbed the "Beast from the East" in March.

Wind turbines: How much power can they provide?

Wind power is an important pillar in Germany's energy policy turnaround: According to the German government, the resource should cover 65 percent of German electricity needs by 2030, along with solar, hydropower and biomass. In a recent study, Dr. Christopher Jung and Dr. Dirk Schindler from the University of Freiburg show that it will be possible to cover 40 percent of the current electricity consumption with wind energy alone by the year 2030. The prerequisite is that the operators distribute the plants optimally on the German mainland. To estimate usable wind energy, the researchers have developed a new three-dimensional model. As a basis for their calculation, they used the number of new installations in 2017. If it remains constant until 2030, Germany can reach the calculated value. The team recently published its findings in the journal Energy Conversion and Management.

A fundamental idea of the researchers while developing the model was to increase the efficiency with which the wind power is used. The scientists show that in particular repowering -- i.e. the replacement of old, small plants with newer, larger ones -- enables enormous increases in yields of up to several hundred percent. As a result, the cost of generating electricity, which is created when the energy is converted into electricity, can be reduced significantly to a level comparable to that of brown coal. However, in order to meet the current expansion targets of the Federal Government, a significant portion of the 30,000 wind turbines must be renewed and 6,000 additional systems must be additionally installed.

Based on the researchers' model, the available wind resources can be determined for all common plant types. Also, the expansion target can be adjusted as desired. Using the model, scientists can develop and assess scenarios in which the plant density, the expansion strategy and the repowering intensity are varied. The model also allows for a balanced spatial distribution. "In principal, we can avoid a disproportionate concentration in certain regions," summarizes Jung. In addition, the algorithm takes into account that the number of new installations to be installed is kept as low as possible. "This would minimize disruptions in the landscape while taking the landscape and nature conservation into account," says Schindler.
