The population of the emirate of Abu ­Dhabi reached 2.3 million in mid-2013 and grew at a rate of 7.9 percent between 2005 and 2012, making it one of the fastest-growing countries worldwide. Migrant workers contributing to the ­Emirate’s economic boom play a major role in this rapid increase. Both demographic and economic growth fuel a sharp rise in power demand. Now, the third combined cycle power plant at the Shuweihat site in the emirate of Abu ­Dhabi has been handed over, turnkeyready. T ­ ogether with its Korean consortium partner Daewoo Engineering & Construction Co., Siemens designed, built, and commissioned Shuweihat S3 to meet Abu D ­ habi’s increasing power needs. In addition, the plant will deliver power to the emirate’s expanding industry – ­including the nearby Ruwais refinery. Situated approximately 260 kilometers west of Abu Dhabi, it is Siemens’ fifth power plant in Abu Dhabi and one of the Emirate’s most powerful and efficient. The Shuweihat S3 combined cycle power plant has an installed electrical ­capacity of 1,600 megawatts and will be operated by Shuweihat Asia O&M Company (SAOM). The owner is Shu­weihat Asia Power ­Company (SAPCO), which is a consor­ umitomo ­Corporation tium comprising S of J­ apan, Korea Electric P­ ower Corporation, and the local utility Abu Dhabi ­Water & Electricity A ­ uthority ­(ADWEA). But Shuweihat S3 excels not only thanks to its highly efficient F-class gas turbines, it is also a benchmark project in terms of Siemens’ efforts to promote ­occupational health and safety. At the Shuweihat S3 construction site, large numbers of workers of different nationalities worked in changing contractor teams simultaneously on site, which makes c­ reating a contin- uous safety culture ­rather demanding. However, the challenge to implement the company’s strict Environment, Health and Safety (EHS) regulations (see also article “The Zero-Harm Mind-Set” p. 52) was met. “The Siemens Zero-Harm safety program, which focuses on improving safety culture from the top down, was implemented within the Shuweihat S3 project – ­encouraging all on site to be proactive about managing safety. Siemens’ efforts in working with our partners and our ­client on the project helped reduce the risk for everyone involved during ­construction and commissioning,” says ­Lothar Balling, Head of Project Man­ agement at the Power and Gas Division of Siemens. For a construction site of this scale, this is an impressive achievement and team effort. Living Energy · No. 11 | December 2014 73 In Short In Short Grid Access Power Transmission Upgrade of German Offshore Grid and GIS Technology Breakthrough First SVC Installed in Colombia’s Industrial Sector The new gas-insulated HVDC switchgear will reduce the size of offshore converter stations. With the installation of the third and fourth high-tech offshore platforms for German-Dutch transmission grid o ­ perator TenneT in the North Sea, an important milestone in efforts to expand the German offshore grid has been reached. The converter stations HelWin1, ­BorWin2, SylWin1, and HelWin2 are fully automated and designed for decades of ­operations in rough seas. Together, the platforms from Siemens will transmit 2.9 gigawatts of wind-based electricity. This year, a fifth converter station – B ­ orWin3 – was ordered. It will start transmitting in 2019. The first Siemens SVC (Static VAR Compensator) for reactive power compensation in Colombia’s industrial sector was installed at Gerdau Diaco’s steel production plant in Tocancipá at 2,560 meters above sea level. Static reactive power compensators boost the operational security and transmission capacity of power grids thanks to voltage stabilization and power feed-in The HelWin2 and SylWin1 DC links were installed this summer. ­SylWin1 will be the most powerful of the four offshore grid connections – it can transmit sufficient wind power onshore to power 900,000 homes. With its dimensions of 83 x 56 x 26 meters, it is the largest ­converter plat­form i­nstalled to date worldwide. However, with the recent breakthrough in gas-insulated technology for DC switch­ gear, the converter stations of the future are set to be significantly smaller. Until now, air-insulated equipment has been the only solution for DC. The 320-kilovolt gas-insulated HVDC switchgear has ­already reached market maturity, and the 500-kilovolt equipment is currently being tested. In the 320-kilovolt configuration, the gas-insulated DC switchgear uses up to 95 percent less space than its air-­ insulated predecessor. This will result in substantial cost savings, since offshore platforms are extremely expensive. Oil & Gas Mergers & Acquisitions Subsea Pipeline Heating Power System in Azerbaijan Dresser-Rand Will Strengthen Oil & Gas Portfolio Siemens will deliver customized topside direct electrical heating (DEH) power supply systems to BP Exploration Limited to be used on ten subsea flow lines. Deepwater natural gas reservoirs and low temperatures cause hydrate formation, which can trigger flow line blockage. The DEH systems will prevent hydrate formation during planned and unplanned process shutdowns in the Shah Deniz gas field in Virtual Power Plant Boosts Utilities’ Business Lifetime Achievement Award for Wind Power CTO Energy ­Training Billing Contract ­Management 74 Living Energy · No. 11 | December 2014 Siemens has entered into an agreement with New York Stock Exchange-listed Dresser-Rand to acquire all of the latter’s issued and outstanding common shares by way of a friendly takeover bid. The offer price is US$83 per share, or a total of around US$7.6 billion (around €5.8 billion). The transaction is expected to be completed by summer 2015.

The cloud-based solution enables smaller utilities to operate their own virtual power plants with a minimal investment by using Siemens technology and collaborating with Mark-E as their market partner. Load & Generation Living Energy · No. 11 | December 2014 75 In Short In Short Wind Onshore Clean Energy for Morocco Mergers & Acquisitions Expansion of the Gas Turbine ­Portfolio Wind Power Wind Turbine for High Yield at Low-Wind Sites Launched In September at the WindEnergy 2014 trade show in Hamburg, Siemens introduced its new SWT-3.3-130 wind ­turbine, developed to extract the ­maximum energy yield from low to moderate wind speeds. With its 3.3 megawatts of electric power and remarkable diameter of 130 meters, this wind turbine will be available in early 2017. It is a perfect fit for the growing number of onshore wind power plants that are being built in regions with moderate to low wind speeds. This new turbine will exceed the annual energy yield of the previous D3-series wind turbines (SWT-3.0-113 and SWT3.2-113) by approximately 17 to 20 percent. Five years of experience gained from the D3 platform have ­enabled engineers to fundamentally rework the main components, such as the direct-drive PMG generator – which now operates with even stronger permanent magnets to further enhance output. More wind turbine innovations are already lined up: Siemens has obtained type certification by certifying body DNV GL for the D6 offshore wind turbine. The model SWT-6.0-154 is based on proven direct-drive technology, rated at 6 megawatts, its rotor spanning an impressive 154 meters. 76 Living Energy · No. 11 | December 2014 By acquiring Rolls-Royce’s aero-derivative gas turbine, compressor, and ­service business for £785 million (€940 million), Siemens is strengthening its position in the growing oil and gas industry as well as in the field of ­decentralized power generation. “The small to medium aero-derivative gas turbines up to 66 megawatts close a technological gap in our gas turbine portfolio,” says Roland Fischer, CEO of the Power and Gas Division. Rolls-Royce’s gas turbines were originally developed for the aviation industry. The weight-optimized turbines are compact and very efficient, making them an interesting option for offshore platforms with limited space, for example. Siemens further purchased exclusive access to future technological developments in aviation turbines from 4 to 85 megawatts and preferential access to delivery and engineering ­services. In the open desert, the gradual construction of no less than 131 turbines is producing a spectacular landscape. The Moroccan government has set itself the target of raising the contribution of ­renewable energy to 42 percent of the national energy consumption by 2020. Under the framework of this ambitious government project, Siemens provides 400 megawatts from its installed bases throughout the country. Upon commissioning in the end of 2014, one of these installations – located in Tarfaya in the south of Morocco on the Atlantic coast – will be Africa’s largest onshore wind power plant with an output of 300 megawatts. Tarfaya’s wind farm required Siemens to deliver and install 131 SWT2.3-101 wind turbines – the designation indicating a power rating of 2.3 megawatts and a rotor diameter of 101 meters – under a five-year ­service agreement. The customer is a joint v­ enture between Morocco’s N ­ areva Holding and International Power Ltd., which is part of the GDF SUEZ Group. In addition to the wind farm, Siemens also made a commitment to give the ­local population access to b ­ etter education and healthcare by providing a school bus and an ­ambulance, as well as IT equipment. Instrumentation, Controls & Electrical Central Control of Heterogeneous Generation Fleets A recent innovation to Siemens’ I&C system SPPA-T3000 allows the central operation of numerous power plants with dissimilar I&C systems. SPPAT3000 can be set up in a multiunit configuration using a new homogenization concept: A transformation ­server is installed at every plant to “translate” the data from the original systems into the SPPA-T3000 data structure. With the system’s uniform operating and alarm h ­ andling philosophy, operators in the central control room thus have control over the entire fleet at all times as if it were one single system. This solution minimizes operational costs and, at the same time, requires only low ­investment, thanks to the retention of existing control systems in each plant.
