JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
The prototype of the G128-4.5 MW wind turbine Gamesa erected at an R&D wind farm in Jaulín (Zaragoza) on the 06th of November achieved a new milestone for energy output by a single turbine in Spain. This multi-megawatt machine generated 97.34 MWh while operating at 100-percent availability.
This same prototype of the G10X-4.5 MW turbine system has achieved three previous milestones for wind energy generation in Spain: on 1 June 2011 -- the date of the highest energy output by a single turbine in Spain (98.26 MWh); 8 October 2011 (96.48 MWh); and 1 March 2011, when the turbine generated 95.19 MWh.
The initial prototype of the G128-4.5 MW, the world's most powerful turbine for the onshore wind energy market, has delivered more than 6 GWh to the Spanish electricity grid this year, at an availability rate exceeding 97%.
This turbine's most distinguishing characteristics include its light weight, despite its size - a 120-metre tower and blades with a diameter exceeding 62.5 metres-; the competitiveness of its cost of energy (CoE); its ease of transport and assembly, comparable to that of a 2.0 MW turbine thanks to its segmented blade -unique in the world- and innovations such as the FlexiFit, a crane coupled to the nacelle and used as a tool for assembling and servicing the device.
The energy produced by just one Gamesa G10X-4.5 MW machine helps to generate an environmentally-benign energy source by preventing the release of polluting atmospheric emissions. The annual output of a single turbine can supply electricity to 3,169 households per year, replace approximately 1,000 tonnes of oil equivalent (toe/year) and prevent atmospheric CO2 emissions of 6,750 tonnes annually.
Wind energy's contribution to the power grid hits a record high
The milestone achieved by the Gamesa turbine on the 6th of November 2011 coincided with an all-time high contribution from wind energy to the power grid.
During a speech at the VII "Intelligent Power Grids: Towards a New Energy Model" conference, Red Eléctrica Chairman Luis Atienza noted that at approximately 2:00 a.m. on Sunday, 6th of November, wind energy accounted for an "all-time high" of 59.6% of electricity demand. This figure exceeds the previous record of about 54%.
