Energy efficiency in the U.S.

As the world faces increasing environmental and economic challenges, Siemens is helping to ensure a balanced energy mix with sustainable solutions that focus on energy-efficient fossil power and clean, renewable energy.

The wind industry, in particular, is playing a pivotal role in achieving a balanced energy mix in the United States. In 2012, wind energy was – for the first time ever – the number one source of new electricity generation capacity. More wind power capacity was installed in the U.S. than any other form of power generation.

As a market leader in wind power technology, Siemens is proud to announce our latest wind project with MidAmerican Energy Company in Iowa. We will supply 448 wind turbines that will generate 1,050 megawatts of wind power for roughly 317,000 Iowa households. Upon completion, wind will account for approximately 39 percent of MidAmerican Energy’s generation portfolio. This project further demonstrates the great potential of clean, renewable power generation in America.

In addition to wind power, Siemens’ technologies are increasing the efficiency of conventional power plants, enabling a more reliable power supply with smart grids, and providing energy-efficient solutions for buildings and industry. In 2012, as a result of Siemens’ sustainable technologies, we helped our customers save 332 million metric tons of CO2 globally.

Wind power technology

Siemens is continually pushing innovation in wind power technology. Our highly efficient, robust and reliable wind turbines meet both energy and environmental needs, as well as drive down the cost of wind power.

Wind turbines from Siemens feature rotor blades tailored to the requirements of the market at all stages of development. The latest revolution – the aeroelastically tailored blade (ATB) – is designed to absorb high wind gusts, which allows for greater energy capture and longer system lifetime.

To further strengthen our commitment to innovation, Siemens has established a research and development center for wind power in Boulder, Colorado.

Wind projects

Siemens has nearly 5,000 wind turbines installed at wind farms throughout the U.S., including Hawaii, Iowa, Kansas, Nevada, North Dakota, Oregon, Pennsylvania, Texas and Washington State.

Providing efficient wind power technology for the U.S.

Using wind power technology, Siemens is helping to provide thousands of U.S. households with clean energy.

Our newest wind projects illustrate Siemens’ successful track record and leadership in supplying reliable, cost effective and energy efficient wind power technology.

In 2013, Siemens received an order from the U.S. public utility Portland General Electric for the supply and installation of 116 wind turbines at the Tucannon River Wind Farm in Washington State. The wind farm, when it comes online in 2015, will supply nearly 84,000 American households with ecofriendly electricity.

Siemens has also received a contract from The National Nuclear Security Administration to construct the federal government’s largest wind farm at the Pantex Plant in Amarillo, Texas. The wind farm’s five turbines will generate annual energy savings on average of $2.8 million and will supply more than 60 percent of the annual electricity required for Pantex.

Recently, Siemens completed the largest D3 platform installation in the world at the Bison IB, II and III Wind Energy Centers in North Dakota. The 85 wind turbines will provide clean electricity to more than 75,000 homes in Minnesota.

The positive economic impact of these projects is helping to revive communities, states and the U.S. as a whole.

Job creation

Siemens’ advances in technology and services are supporting the growth of the next energy boom and are playing a key role in the expansion of the wind industry in the U.S.

As the wind industry develops, it is creating new jobs throughout the U.S. Siemens is contributing to this job growth with the creation of more than 50 jobs at the recently opened Siemens Wind Service Training Center in Orlando, Florida.

The center, which will serve all of the Americas, provides wind technicians with highly advanced technical and safety training for the installation, service and maintenance of wind turbines.

The American manufacturing sector will also benefit from the production of the 448 new wind turbines for the MidAmerican Energy wind expansion project. The rotor blades will be produced at Siemens’ facility in Fort Madison, Iowa, while the nacelles and hubs will be assembled at Siemens’ facility in nearby Hutchinson, Kansas.

Energy-efficient fossil power generation

Fossil fuels also remain an important part of maintaining a stable energy network in the U.S. and it is crucial to use these scarce resources as efficiently as possible.

Gas turbines, combined cycle power plants, and combined heat and power plants all contribute to energy efficiency in fossil power generation. With a capacity of 375 megawatts, Siemens has produced the world's most efficient gas turbine. Siemens will supply two gas turbine packages for the Mississippi Power Company, which will be installed in a coal-fired integrated gasification combined cycle (IGCC) power plant in Liberty, Mississippi. Approximately 65 percent of the turbines’ CO2 emissions are expected to be captured. The plant is expected to go into operation in 2014.

Efficient fossil power generation can lead to high levels of industrial energy efficiency in the U.S.

In El Segundo, California, Siemens has inaugurated a new Flex-Plant for the U.S. power company NRG Energy. The project offers an environmentally compatible solution that has extremely short startup times and is low on startup emissions and water usage. The plant opened in September, 2013, and is now the second Flex-Plant to have opened in California – following the Lodi plant, which began commercial operation last year. The power islands have a total installed capacity of 550 megawatts, and have the potential to supply 450,000 Californian households.

The Lodi Energy Center offers energy efficiency levels of over 57 percent.

Saving energy with efficient power transmission

Reliable and low-loss transmission is an important element of sustainable energy usage. Siemens energy management systems ensure the continuous reliability of one-third of all transmission grids in the U.S.

The transmission of power over great distances with the high-voltage direct current (HVDC) transmission system is both energy-efficient and environment-friendly. HVDC minimizes power losses and line costs of overhead lines for distances longer than 600 kilometers.

Siemens supplies high-voltage direct current technology for projects all over the world. Notable examples in the U.S. are the Neptune Project, a power highway between New Jersey and New York, and the Trans Bay Cable Project in the San Francisco bay area. For the latter, Siemens implemented its HVDC PLUS technology for the first time. The key advantages of the new HVDC PLUS link are its increased network security and reliability due to network upgrades and reduced system losses.

Energy conservation with power distribution

Smart grid technology is another example of low-loss transmission and smart distribution. Smart grids enable a more efficient, reliable and secure power supply: Research has shown that by 2020, more than one billion tons of CO2 emissions could be abated with the use of intelligent power networks.

The Hawaiian Electric Company is embarking on a project to develop a self-healing grid that will provide reliable electricity to eastern Oahu and Waikiki. This smart grid project will prove it possible to satisfy Hawaii’s growing energy needs without expensive construction and expansion in a fragile environment. Siemens will be contributing latest technologies to modernize the energy distribution infrastructure of eastern Oahu. An interactive, digitized, intelligent electric grid vision is becoming reality for Oncor, the largest distribution and transmission company in Texas. Oncor’s smart grid will connect power providers and customers to improve reliability in the deregulated Electric Reliability Council of Texas (ERCOT) market and provide services across the Oncor system.

Smart electromobility

Electric cars have low emissions. By integrating electric vehicles into the smart grid, they become a part of the energy system instead of simply consuming energy. During peak power generation times – for example periods of strong wind or intense sunshine – electric vehicles store energy which is returned to the grid in times of high demand. The interaction of renewable energies and sustainable mobility has great potential of becoming electromobility’s most important contribution toward climate protection.

Electric cars are quiet, clean and sustainable. One million electric cars will be on the road in the U.S. by 2015. Los Angeles, San Francisco, and San Jose, California, are the pioneering cities here and they will pass their experience on to other urban areas. The U.S. government plans to invest $140 billion and become the world’s leader in electromobility. Siemens is actively involved in a variety of activities in the field of electromobility and covers the entire process chain – from developing intelligent infrastructure solutions and charging technologies to researching the requisite drive technologies.

Energy-efficient homes

Buildings offer immense potential for energy conservation in the U.S.: They are responsible for 40 percent of our energy consumption and 21 percent of the world’s greenhouse gas emissions. Intelligent building technology positively impacts the energy efficiency, the conservation as well as the comfort of buildings, while also raising the productivity of occupants and companies.

Energy performance contracting

Performance contracting means paying for the cost of a building renewal project with utility bill savings that result from the installation of the new energy-efficient building system. Within the framework of energy-efficient contracting, Siemens determines and develops energy potentials by means of selective modernization and optimization. Not only does this lower operating costs, it also cuts CO2 emissions, increases property values and enhances operating safety. Energy-efficient buildings with guaranteed lower energy costs create virtually no cost for the customer because the savings pay for the investment. Since 1994, Siemens has completed more than 1,000 energy efficiency projects that have cut energy costs by more than $2 billion and reduced CO2 emissions by about 1.2 million, tons which is the equivalent of approximately 300,000 passenger cars driving 20,000 kilometers a year. The market potential of energy efficient buildings in the U.S. is estimated at more than $20 billion over the next 10 years.

Buildings as prosumers

More and more buildings can become prosumers, meaning they not only consume electricity but also produce it. An increasing number of buildings in industrialized countries are equipped with photovoltaic or small wind-energy systems that transform them from energy consumers to active participants in the energy market. Due to intelligent electronic electricity meters, improved demand estimates and active building energy management, buildings are becoming more and more important as prosumers.
