Today, Gamesa unveiled its new 2.5-MW turbine, specially designed for less windy conditions, at the international trade fair China Wind Power 2015 (Beijing, 14-16 October): the Gamesa G126-2.5 MW, designed to maximise output, efficiency and profitability.

This new turbine combines a longer rotor (126 metres in diameter), nominal capacity of 2.5 MW and a range of tower heights to choose from 84, 102 and 129 metres (among other customisable features depending on site conditions).

Thanks to its extremely low power density, an outstanding capacity factor and a lower cost of energy, this turbine will boost energy production with respect to the G114-2.0 MW by up to 25%.

Underpinned by technology which has been exhaustively proven and validated in Gamesa’s 2.0-2.5 MW platform, with installation of over 20,000 MW in 34 countries worldwide to its name, the G126-2.5 MW is fitted with the same electric system as the rest of the company’s 2.5 MW products (the Gamesa G106-2.5 MW and Gamesa G114-2.5 MW). In addition, the blades, 62 metres long, are equipped with the technology already validated in the G114’s 56-metre blades. The first prototype will be installed during the third quarter of 2016 and its serial production is due to begin by 2017.

With this new model, Gamesa’s 2.0-2.5 MW platform cements its position as one of the most versatile platforms in the market: seven choices of rotor (80, 87, 90, 97, 106, 114 and 126 metres), tower heights ranging from 55 to 129 metres and customisable options which enable installation in the most complex sites.

The need to install offshore wind turbines in increasingly deeper water will create a demand for larger and heavier foundations and therefore, for cost effective designs. New innovative foundation designs for offshore installations could prove to be more cost effective than conventional foundations for projects involving deeper waters and larger wind turbine sizes. These are the findings of a commercial study carried out by mec these are the findings compares various offshore wind foundation designs based on multiple cost parameters.

MEC Intelligence has launched a commercial study that compares the cost of a range of offshore wind foundation designs. Conventional foundation designs such as monopiles and jackets have been compared with new innovative designs such as gravity-based and suction-based foundation designs. The results of the study indicate that innovative foundation designs could prove to be more cost effective than conventional foundations for projects with increasing depths and turbine sizes.

Foundations represent a large investment in the construction of an offshore wind farm, with around a 21% share of the total cost of an offshore installation. Foundation cost is primary driven by materials (50-60%) and installation costs (15-25%), together representing 65-85% of the total outlay. Read more…

DanTysk offshore wind farm in the German North Sea was officially. Siemens has supplied, installed and commissioned 80 wind turbines for the 288-MW project, each designed to generate 3.6 MW of power and equipped with a 120-me rotor. Now Siemens wind turbines with a total capacity of over 1 GW feed offshore wind power into Germany’s power grid.

Owner and operator of DanTysk wind park is a consortium comprising the Swedish power company Vattenfall and Stadtwerke München, Munich’s municipal utility. The wind power plant can generate up to 1.3 GWh of electricity every year – equivalent to the total annual consumption of about 400,000 German households.

DanTysk offshore wind farm is located approximately 70 km offshore west of the German island of Sylt. In waters measuring between 21 and 32 meters deep, foundations anchored in the seabed provide the base on which the wind turbines were erected. The wind turbines are not the only thing Siemens is providing DanTysk: the German technology group is taking charge of preventive and corrective maintenance to the wind turbines within the scope of a five-year service agreement, and also supplied the turnkey grid connection for the wind power plant, called SylWin1. This direct-current (DC) offshore link, run by the transmission grid operator TenneT, comprises the connecting systems that connect the offshore wind power plant to the German electricity grid. SylWin1 consists of an offshore converter station at sea, and a receiver station on land, 160 kilometers of undersea cable and further 45 kilometers of underground cable on shore. Overall, three offshore wind power plants will be connected to the grid via this offshore link.

Gamesa has received two new orders in China for the supply of 50 MW to Hebei Construction & Investment Group (HCIG) and 48 MW to Fujian Energy. Under the terms of the contract signed with HCIG, Gamesa will supply, install and commission 25 of its G97-2.0 MW wind turbines at the Senjitu II wind farm located in the province of Hebei, in south-west Peking. The wind turbines are scheduled for delivery this year.

Elsewhere, the agreement reached with Fujian Energy encompasses the supply, installation and commissioning of 24 of the firm’s G97-2.0 MW wind turbines at the Dingyanshan wind farm located in the province of Fujian. These wind turbines are custom-designed to withstand the extreme winds typical of this coastal area which is often hit by typhoons. These turbines are due for delivery during the fourth quarter of 2015 so the project can be commissioned by the end of the year.

Gamesa’s ability to tailor its wind turbines to its customers’ individual needs, coupled with its command of the wind value chain, have enabled it to consolidate its presence in the Chinese market, where the company notched up orders in 2014 for the supply of 450 MW. Gamesa’s presence in China, where it has emerged as one of the leading non-Chinese OEMs, dates back 15 years, having installed over 3,570 MW and with 960 MW under maintenance. China accounted for 9% of Gamesa’s total MW sold in 2014.

Acciona Windpower, the Acciona Group subsidiary dedicated to the design, manufacture and sale of wind turbines, has reached agreement with Atlantic Energias Renováveis and the British private equity firm Actis to supply 195 megawatts (MW) –sixty-five 3 MW wind turbines– for a wind power complex located in the State of Piauí (northest Brazil).The project, developed through a joint venture between Atlantic and Actis, one of Atlantic’s shareholders, consists of eight wind farms: Lagoa do Barro I-VII and Queimada Nova.

With this contract, Acciona Windpower reaches 1,020 MW sold of its AW3000 wind turbine in Brazil, since it started marketing it in 2012.

The model selected in this contract is the AW125/3000, which has a rotor diameter of 125 meters. It is designed to optimize energy capture on sites with medium-speed prevailing winds in the area where the complex will be installed. The turbines will be mounted on 120-meter-high concrete towers.
The production associated with this project was awarded to Atlantic in the A-5 auction organized by the Brazilian Government in November 2014.

Supply of the wind turbines will begin in 2017, with the aim of the complex becoming operational in the second semester of 2018.The agreement establishes that Acciona Windpower will operate and maintain the installation for 15 years.

Local components

The main components of the wind turbines to be supplied under this contract will be manufactured in Brazil. The nacelles will be assembled in the new plant Acciona Windpower has opened in Simões Filho (Bahía) and the concrete towers will be assembled on site, with the segments manufactured in a company facility located nearby.

The blades and other equipment will also be purchased in Brazil. This means that the company complies with the requirements regarding national production of components established by the BNDES (Brazilian National Development Bank) to finance the purchase of wind turbines under more favorable conditions than in the market.

Siemens and the Egyptian government have reached firm agreements to build a 4.4 GW combined-cycle power plant and install wind power capacity of 2 GW. Siemens will build a factory in Egypt to manufacture rotor blades for wind turbines, creating up to 1,000 jobs and therefore nearly trebling Siemens’ footprint in the country. The agreements were signed at the Egypt Economic Development Conference in Sharm el-Sheikh in the presence of Egypt’s Minister of Electricity Shaker al Markabi, Germany’s Vice Chancellor Sigmar Gabriel, and Joe Kaeser, President and Chief Executive Officer of Siemens AG. Including two further Memorandums of Understanding (MoU) which were signed at the event, Egypt’s power generation capacity will be massively increased by up to one third mostly by 2020. Under the agreements, Siemens will propose to build additional combined cycle power plants with a capacity of up to 6.6 GW and ten substations for reliable power supply.

According to the agreement, Siemens will be the contractor responsible for engineering, procurement and construction (EPC) for the Beni Suef power plant in Upper Egypt, and will work together with local partners. The 4.4 GW power plant will be built in four modules, each consisting of two H-class gas turbines, two heat recovery steam generators, one steam turbine, and three generators.

Adding two gigawatt will be a significant step towards diversifying Egipto’s energy mix. Egypt has great potential for wind power generation, especially in the Gulf of Suez and the Nile Valley. The Egyptian government plans to expand wind capacity over the coming years as part of a plan to increase wind generation to 7.2 GW by 2020.

Gamesa has received its first order from Germany energy provider DEW 21. Specifically, it has been contracted to build the 12-MW Horst wind farm located in the town of Schneverdingen, in Lower Saxony, under a turnkey arrangement. Given the fact that it is a turnkey contract, Gamesa will handle all the tasks necessary to develop the wind farm, from obtaining the required licences and permits to performing the civil engineering and electrical wiring work needed to build and operate the project, while also transporting, installing and commissioning the wind turbines.

The Horst wind farm will be equipped with six G97-2.0 MW turbines, slated for delivery from July; the wind farm’s commissioning is scheduled for November 2015. Once operational, the facility will generate enough electricity to supply over 8,500 German households.

Gamesa’s presence in the German market dates back to 2003. In its capacity as developer, it has developed and commissioned over 263 MW in this market where it currently has a pipeline of close to 236 MW at varying stages of development. In its capacity as manufacturer, it has installed 185 MW of its turbines and operates 57 MW under O&M agreements.

In partnership with the Société d’Exploitation de la Tour Eiffel, UGE International Ltd, has installed two on-site wind turbines at the Eiffel Tower as part of a high-profile renovation and upgrade to the first floor of the monument. Located above the second level for its wind conditions, the turbines are now producing 10,000kWh of electricity annually, equivalent to the power used by the commercial areas of the Eiffel Tower’s first floor. UGE designed the wind energy system to provide a clean source of energy at the Eiffel Tower, which is undergoing its first major face-lift in 30 years. The two UGE VisionAIR5 wind turbines were specially painted to match the iconic tower, and top off a series of other efficiency upgrades.

The Eiffel Tower’s vertical axis wind turbines are virtually silent and designed to capture wind from any direction, offering a unique addition to the historic structure. The location for the wind turbines, 400ft (120m) above ground level, was strategically chosen to maximize energy production, allowing the wind turbines to harvest the steady winds at the height of the installation and offset the Tower’s energy usage. Mounting the turbines at this location was itself a technical challenge, requiring each component to be hoisted and suspended with ropes to the Tower’s second level.

“The Eiffel Tower is arguably the most renowned architectural icon in the world, and we are proud that our advanced technology was chosen as the Tower commits to a more sustainable future,” said Nick Blitterswyk, CEO of UGE. “When visitors from around the world see the wind turbines, we get one step closer to a world powered by clean and reliable renewable energy.”

Although there is no ‘High Quality Environmental’ benchmark for the Eiffel Tower, one of the major goals of the face-lift was to achieve a significant reduction in its ecological footprint as part of the City of Paris Climate Plan.

In addition to wind energy, the renovation also includes LED lighting and 10 m² of roof-mounted solar panels on a visitor pavilion whose output will meet approximately 50% of the water heating needs of the two pavilions. High-performance heat pumps have also been installed to ensure a constantly balanced temperature. The two pavilions also have gained a rainwater recovery system that provides flushing water to the toilet facilities.

In addition to the Eiffel Tower, UGE has designed wind, solar and microgrid systems in more than 90 countries around the world for global brands including Whole Foods, Hilton, Dropbox and Verizon.
