Hamburg, 30 June 2017. In February this year the Nordex Group installed a 3 MW turbine on a 134 metre tubular steel tower in a test field operated by windtest grevenbroich gmbh for GP Joule, a project developer. Prior to this the manufacturer had always installed its turbines with hub heights in excess of 120 metres in continental Europe on hybrid towers - a combination of concrete and tubular steel towers. The reason for this is that for very high hub heights the diameter of a conventional lower tubular steel segment would be more than 4.30 metres, which would make it impossible to transport them under bridges. The diameter of the lower segment of the new tower is exactly 4.30 metres, which solved the bottleneck problem. The aim of the new tower concept is to extend the know-how and experience with respect to high towers as an alternative to the use of hybrid towers. The results of the latest tests conducted already confirm that the tubular steel tower is perfectly suitable, also given the 20-year service life of the turbine. From the middle of next year this tower technology will initially be available for international markets for the recently launched

ALMERE, THE NETHERLANDS – Unfortunately, sometimes wind turbines cannot be used even though it is a windy day. The energy that is generated is more than the power grid can absorb and gets lost. This problem is now being solved at Nuon’s Prinses Alexia Windpark in Zeewolde, the Netherlands. Dutch company Alfen developed a mega energy storage system by connecting a large number of BMW car batteries. The system stores the surplus of energy so that it can be used when the grid requires the power at a later moment in time. Solution for unused wind energy Nuon invests in the generation of renewable energy from wind and sun. It is of course a pity if this renewable energy cannot be used. 'Use it or lose it'; has always been the dilemma for renewable energy from the sun and wind. The Alfen mega energy storage system helps to smooth peaks and troughs in power supply and better match the demand for energy. In this way we are creating more flexibility and stability in the system to facilitate renewable energy. 3 megawatt energy storage system at Prinses Alexia Windpark Together with BMW and Nuon, Alfen launched its 3 megawatt storage system at the Prinses Alexia

With the development of Galloper Offshore Wind Farm underway, an extension of the fully operational Greater Gabbard Wind Farm off the coast of Suffolk, Collett were tasked with providing transport logistics for a 180Tonne Transformer destined for the onshore substation. Originating in South Korea the Super Grid Transformer, which measures an impressive 8.7m (L) x 4.9m (W) x 4.7m (H) was scheduled to arrive at the Port of Lowestoft via Rotterdam in late September. With the instruction of the project, on behalf of Hemisphere Freight Services, beginning in June this provided a tight four month timescale in which to plan, execute and complete the delivery. Working closely with Hemisphere Freight Services Ltd and Robert Wynn & Sons, a solution for transferring the transformer from the originating vessel at Rotterdam to the specialist RoRo barge, the Terra Marique was devised. In collaboration Collett, Hemisphere and Wynns engineered specialist calculations and technical drawings of the loaded cargo to confirm the transformer’s stability and safety whilst on board the vessel. On arrival in Lowestoft the vessel’s hydraulic roadway would provide the option of delivering onto varying quay heights enabling the approach during high tide.

New figures show that onshore wind is powering ahead in Northern Ireland, generating nearly a quarter of its electricity needs. The latest generation figures released by NI Electricity Networks, show that onshore wind has now passed the 1GW milestone, with 1,029MW of onshore wind connected in Northern Ireland. This year has seen significant delivery of large onshore wind projects, representing £127.4million of local investment since the beginning of 2017. The growth has contributed to official figures published this month showing that in the 12-month period from April 2016 to March 2017, onshore wind generated 22.4% of Northern Ireland’s electricity. All renewable sources contributed 27.1%. In the UK as a whole, onshore wind currently provides 6% of electricity, so proportionately Northern Ireland is way ahead in terms of generation from this power source. Onshore wind is now by far the leading source of clean electricity in Northern Ireland, representing 78% of installed renewable capacity. With world-leading grid management systems, the network is dealing with increasingly high levels of renewables, maximising the growth potential of these technologies. The Chair of NIRIG (Northern Ireland Renewables Industry Group) Rachel Anderson said: “Crossing this 1GW threshold shows just how much of a success story onshore wind is in Northern Ireland.
