 Mitsubishi Heavy Industries Ltd. (MHI) has received an order for major components of natural gas-fired gas turbine combined-cycle (GTCC) power generation systems with heat supply capability, which will be installed in a cogeneration facility to be built by Huaneng Power International Inc., one of the major electricity providers in China. The order was placed through Dongfang Turbine Co., Ltd., a major power generation equipment manufacturer in China to which MHI has licensed its gas turbine technology. MHI will provide two M701F gas turbines as well as major components of a steam turbine. Delivery of the gas turbines is scheduled in February and March of 2011.
The GTCC cogeneration facility in Gaobeidian, in which the gas turbines and other components are to be installed, is the first of six projects that is planned near Beijing area. The facility with 920 MWe (megawatt electrical) during the summertime, or 830 MWe as well as 660 MWt (megawatt thermal) during the wintertime, will provide electricity and heat to meet the fast-growing demands in the nation's capital city and surrounding area.
For the facility, MHI will specifically supply two gas turbines, control system components, and steam turbine components. Dongfang Turbine will deliver the gas turbine auxiliary system, steam turbine and its auxiliary system to Huaneng Power International through Dongfang Electric Corporation, the parent company of Dongfang Turbine. Mitsubishi Corporation will handle trade particulars.

 Dong Energy has opened its new British offshore wind farm, Gunfleet Sands, which is expected to supply green power corresponding to the annual power consumption of some 125,000 British households. The wind farm is located in the Thames Estuary off the Essex coast.
The total capacity of the offshore wind farm is 172MW. Gunfleet Sands 1 consists of 30 turbines each of 3.6MW and Gunfleet Sands 2 consists of 18 turbines each with a capacity of 3.6MW. The rotor diameter of the turbines is 107m, with a maximum height of 129m from blade tip to sea level. The total area of the phase 1 development is 10km2 and 7.5km2 for phase 2.
The project makes a considerable contribution to the domestic UK target of reducing CO2 emissions by 20% below 1990 levels by 2010.
Dong Energy is involved in building the three new offshore wind farms, London Array (630MW), which is due to be commissioned in 2013, and Walney (367MW) and Lincs (270MW), which are scheduled for completion by next year.

American Superconductor company (AMSC) and South Korea-based Hyundai Heavy Industries (HHI) have expanded their strategic alliance to jointly develop a 5MW full conversion wind turbine, primarily for use in the burgeoning offshore wind industry.
Under the terms of the alliance, the 5MW wind turbine design will be developed by HHI and AMSC’s wholly-owned subsidiary AMSC Windtec.
Once HHI begins volume production of the wind turbines, which is expected to commence by the end of 2011, it will purchase power electronic components for the 5MW wind turbines from AMSC.
In October 2008, AMSC Windtec licensed doubly-fed 1.65MW and 2MW induction wind turbine designs to HHI, of which, HHI has already begun volume production of the 1.65MW turbines.
HHI has also ordered an initial ten wind turbine electrical control systems from AMSC for use in its first 2MW wind turbines and said it plans to commission its first 2MW wind turbines by mid-June, with the intention of entering volume production of these wind turbines by the end of this year.

 GE has developed the world’s first two-stage turbocharged gas engine and is applying this game-changing technology to its Jenbacher J624 gas engine. The new engine provides significant output and efficiency increases compared to the single turbocharged version and is particularly well-suited for operation in hot environments and combined heat and power (CHP) applications.
With the new system, which GE developed with specialists from ABB Turbo Systems Ltd, the J624 achieves approximately 10 percent higher output, increasing from 4 megawatts (MW) to 4.4 MW and offers an electrical efficiency of 46.5 percent, an increase of about 1 percentage point. Improved efficiency is critical for the competitive cost of electricity and for the reduction of CO2 emissions in a carbon-constrained environment.
In addition to the higher charging pressure, this technology also significantly improves the power density of the engine allowing it to run beyond 22 bar BMEP1 (brake mean effective pressure).
Applications for the new two-stage turbocharged gas engine include independent power producers, CHP, trigeneration and special applications using natural gas fuel, as well as a wide range of non-natural gas fuels. The new engine will be available to customers worldwide by the summer of 2011.

Endesa, the Spanish energy supplier, has completed the extension to its power plant in Ceuta with the installation and commissioning of an MAN 12V48/60B engine. MAN Diesel & Turbo, Spain negotiated the contract for the new engine that includes the supply of an SCR (Selective Catalytic Reduction) system.
The 12V18/60 engine is the fourth such engine installed at Ceuta and has been Endesa’s engine of choice for many of its other power plants. The integrated SCR system significantly reduces NOx emissions at the plant and hence Endesa’s environmental impact locally.
With the installation of the engine, termed “Group 13” under its project classification, four MAN 12V48/60 models are now in operation at the power plant in Ceuta. The Ceuta engine, “Group 9”, has an “A” turbocharger configuration while the rest, “Groups 10 and 13, have “B” turbocharger configurations.
The MAN 12V48/60B engine is a four-stroke, medium-speed diesel engine with turbocharger and cooling charge air that is specially designed to run on heavy fuel oil (HFO) and diesel oil for start-up/shut-down. In comparison with other similar engines, the 12V48/60 model features a high power supply and a compact and efficient design.
The auxiliary systems that complete the scope of supply are standard for this kind of engine, with the exception of the SCR system.

RWE Innogy, Stadtwerke München (SWM - Munich Municipal Utility) and Siemens have entered into a joint venture to build the offshore wind farm Gwynt y Môr (Welsh for “wind in the sea”). RWE Innogy will hold a 60% stake in this joint venture, Stadtwerke München 30% and Siemens 10%. The total investment amounts to more than two billion Euros, including the grid connection to the coast. The investment will be divided between the partners accordingly.
Gwynt y Môr is to be built with an installed capacity of 576 megawatts in Liverpool Bay, around 18 kilometres off the North Wales coast. Work will start towards the end of 2011 to erect the first foundations for a total of 160 wind turbines. All permits for the wind farm covering an area of 79 square kilometres have already been obtained. Siemens will supply, install and maintain the wind turbines, and provide the connection to the grid.
Construction is expected to start near the end of 2011 to erect the first foundations for a total of 160 wind turbines. All permits for the wind farm covering an area of 79 square-kilometers have already been obtained. Siemens will supply, install and maintain the wind turbines and provide the connection to the grid.
In its first phase of expansion, the wind farm is planned to generate electricity as early as 2013. The project is scheduled to be completed in 2014 and is expected to generate around 1,950 GWh of electricity annually.
Siemens Energy will supply, install and maintain the wind turbines, and provide the connection to the grid.

 San Diego wind farm developer Cannon Power Group and Spanish wind turbine builder Gamesa are planning to build one of the largest wind farms in North America. The companies have started to build a wind farm South of the Border to supply clean power to a quarter of a million households in both Mexico and California from 500 MW of power until 2015. And the potential capacity of the site is ultimately 1,000 MW.
Gamesa and Cannon will collaborate on more wind farms that Cannon has plans to develop in Baja California (Mexico), with Gamesa supplying some development assistance and the wind turbines. They have have signed a 10-year exclusivity agreement.
The farm will be one of the largest in North America because its turbines will be spread out across 140 square miles. The initial phase will include an installed capacity between 70 and 100MW.
