Siemens receives its first wind power order in Chile

Siemens has received an order for a total of 50 wind turbines with a combined capacity of 115 megawatts (MW) for the El Arrayán wind power plant in Chile. This wind project will be developed as a joint venture between Pattern Energy and AEI. Furthermore, the mining division of Antofagasta plc, which is the parent company of Minera Los Pelambres, the power offtaker, has purchased an equity stake in the El Arrayán project. The scope of supply encompasses delivery, installation and commissioning of 50 SWT-2.3-101 wind turbines with a power rating of 2,3 MW and a rotor diameter of 101 meters, including a five-year service and maintenance contract. Installation of the project is scheduled to begin in spring 2013, with commissioning of the wind power plant planned for early 2014.
"The El Arrayán wind power plant marks our market entry in Chile. This project also proves that we are well positioned on the global wind markets with our product portfolio. It is our goal to grow our presence in this region", said Felix Ferlemann, CEO of the Siemens Wind Power Division. The Global Wind Energy Council concluded that Chile has good wind resources from the northern deserts to the extreme South and estimates the country's wind energy potential to be around 40 Gigawatt (GW).
The El Arrayán Wind Farm is located approximately 400 kilometers north of Santiago on the coast of the Coquimbo IV Region. Once completed, it will be the largest wind project in Chile and provide clean and renewable energy to power the equivalent of up to 200,000 average households.
Other Siemens wind orders in South America include three projects with a combined capacity of nearly 300 megawatts (MW) in Brazil, which will be installed in 2012 and 2013. These contracts were secured during the last two years. The 2.3 wind turbines are the workhorses of Siemens` portfolio. At the end of 2011 more than 3,700 units were installed globally.
Wind Power is part of Siemens' Environmental Portfolio. In fiscal 2011, revenue from the Portfolio totaled about €30 billion, making Siemens one of the world's largest suppliers of ecofriendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by nearly 320 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

Desigo V5: Innovations from Siemens increase building efficiency
The Siemens Building Technologies Division has introduced version 5 of its Desigo building automation system. Its innovative products such as Total Room Automation as well as efficiency features, like RoomOptiControl and Eco Monitoring, give building operators and users an active role in energy management, leading to permanent reductions in energy and maintenance costs.
A state-of-the-art building automation system is always optimized for energy-efficient operation. However, these optimized settings may start to drift over time. One of the underlying causes is often a lack of transparency for users who simply don't know how the setpoint changes they make can impact energy consumption. This is particularly true for air-conditioned rooms which are also equipped with lighting and sun protection controls. The new version of Desigo keeps room users and building operators apprised of the building's efficiency status. Feedback to users is given using the innovative Green Leaf display, adapted to the expertise and control options of each user group. The system makes it possible to change settings if needed to restore optimal energy efficiency. A study by Technische Universität München (TUM) indicates that by actively involving operators and users in the energy management of a building, energy consumption can be reduced by up to 25% without affecting comfort.
Total Room Automation offers energy savings without reducing comfort
The open, programmable room automation range Desigo Total Room Automation (TRA) is a holistic solution encompassing the HVAC, lighting and shading disciplines. Desigo TRA uses an innovative efficience feature called RoomOptiControl. It automatically detects unnecessary energy consumption in the room and notifies users by changing the color of the Green Leaf icon on the QMX3 room control unit: If room operations are energy efficient, this icon is green. If settings made by a room user lead to unnecessary energy consumption, the icon turns red. To reset room control to energy efficient operation, the user simply presses the display and the Green Leaf icon returns to green.
Using BACnet/IP, PXC3 room automation stations—also part of the TRA package—are integrated seamlessly into the PX automation level with its primary systems (heating generators, HVAC main units and cooling generators). The primary systems are controlled directly through the demand signals from the rooms. This means that the primary systems are only turned on if needed and their operation is adjusted so it meets the room requirements without exceeding them. One room automation station can cover multiple rooms. TRA offers complete integration of KNX, DALI and EnOcean devices; existing or new sensors and actuators from Siemens can be incorporated as well.
Eco Monitoring to reduce energy consumption and wear
Eco Monitoring is another innovative efficiency feature of Desigo. It monitors ongoing operations of HVAC systems based on energy-related quality condition indicators such as readings from temperature, humidity and pressure sensors, runtime, switching behavior and operational performance of the systems. Should deviations from the target state, inefficient operations or increased energy consumption occur, the building operator is notified via the Green Leaf display on the Desigo Insight management station. Current and future international standards (such as EN 15323:2007) require such a feature in order to optimize building operations over the long term.
Desigo Eco Monitoring not only helps optimize energy consumption, it also reduces wear. Thanks to its dynamic behavior and timely reporting, the Eco Monitoring feature recognizes unfavorable system operations early on, allowing operators to intervene immediately before any negative impact occurs. If desired, operators can choose to be notified of unusual events via text messaging (SMS), fax or e-mail.
Expanded networking of the automation level
Starting with version 5, Desigo also offers expanded end-to-end networking of the automation level. Enhanced support for communications standards ensures efficient system integration. The PXC series of compact automation stations has a higher number of universal inputs/outputs, which makes them much more flexible. To protect existing investments, different device generations, such as PTM and TX I/O modules and RXC room controllers, can be used in parallel on the same PX automation station.
