Long-term drivers in the energy market are the cause of a current systematic optimization of
the energy system. The demand for energy is growing worldwide a fact without doubt. It is
expected to grow at an annual rate of 2.2 percent and climb from 20,300 terawatt-hours today
to 33,000 terawatt-hours by 2030. The second major driver is the need for replacing aging and
outdated energy infrastructure. And third, there is the massive challenge to put the global energy
system on a sustainable basis. To handle all these drivers, we are focusing on a major field to
manage the revolution in the energy market: the systematic optimization of the energy system.
Behind this phrase is an intelligent network infrastructure the Smart Grid.
To meet the growing demand for power, an intelligent and flexible grid infrastructure, smart
generation, and smart buildings will be essential. In traditional power grids, power generation
follows load. But in the future, power consumption will follow generation rather than vice versa.
Prime examples here are electric cars that can be charged or operated at night drawing oncheap wind power. This means we are heading towards a paradigm shift. Towards leaving
unidirectional energy and communications flows behind for bidirectional power flows.
Siemens, a worldwide leader in the field of Smart Grid technology, makes possible the vertical
and horizontal integration of all elements within a Smart Grid and beyond. Even better, these
products, systems, and solutions are readily available.
Discover on the following pages how a Smart Grid can become reality with Siemens
technology.

A reliable, comprehensive,and flexible charginginfrastructure: its real.
An idea over 100 years oldis back in the center of attention
Climate change, gas prices, the increasing demand for mobility, new
technological developments for engines and batteries all these factors
contribute to the fact that an old idea is coming back to life: electric
automobiles, e-cars, are creating a surge of development and are the
cause of exciting new alliances. Cars are turning into mobile energystorage units with the ability to re-feed energy back to Smart Grids.
E-cars, therefore, become much more than environmentally compatible
vehicles: they are an important element of an intelligent energy
infrastructure and contribute to the grids ability to compensate for
fluctuating infeed from renewables and distributed generation units.

profitability of electrical networks. Consequently, telecontrol and online
monitoring of substations improve operational safety. Moreover, the
standardization of protocols and interfaces makes network solutionsmore flexible and accessible.
Smart metering solutions from Siemens combine sophisticated metering
functions, the management of distribution networks, and the integration
of back-end IT systems. These solutions were specially developed to suit
the new challenges the liberalized energy market poses on distribution
network operators and energy retailers and ensures maximum

A building that communicateswith the grid reduces yourenergy costs, and even earnsyou money: its real.
Actively engaging consumers in amaximally efficient network
Buildings account for 40 % of the worlds energy consumption and 20 % of
total CO2 emissions. Therefore, Smart Buildings play a central role in the
Smart Grid as they provide a huge potential for energy efficiency. Actively
influencing their consumption and generation, Smart Buildings support
grid stability and allow generators to consider other options before addingnew generation facilities. Leveraging e-cars and related energy storage
technologies, Smart Buildings have become a key component of the
Smart Grid.
How Smart is a Smart Building?
Smart Building optimize their own energy flow by balancing
consumption, storage capacity and decentralized generation
Interacting with the grid, Smart Buildings can decide on energy
purchasing or selling based on current tariff levels
Smart Building clusters become an interactive part of the grid by providing
significant generation capacity and demand management potential E-cars will become an additional flexible storage capacity for Smart Buildings

You are back at the office. It is late afternoon,
and the current heat wave has lasted two
weeks now. You turn away from your
computer and the heaps of e-mails, and you
look out of the window at the picturesque,
ever-growing city you call home. It persistently
amazes you how high-tech this former town
has become, and you wonder how the grid
can dependably keep up with the electricity
demand of this growing metropolitan area.
But perhaps what is even more amazing for
you is how your building has managed to stay
comfortable throughout that heat wave and
still has managed to save tons of cash on
energy costs. Of course, since you oversee
energy costs, you are well aware of the
reason: Your building knows to store energy
when prices are most favourable for later use
when prices are much higher. It even knows
the best time to deploy renewable energy
sources for its own use and when to sell
supply back to the grid.
Real answers for energy optimisation in buildings
Siemens smart building solutions make it possible for buildings to take
advantage of automated demand response programs that immediately
shift electricity demand from the least critical functions to where poweris most needed.
Furthermore, they automatically store energy for later use when prices
are most favorable. They even know the best time to use one-site
renewable sources like sun or wind and when to refeed energy to the grid,
thus making money on energy instead of spending it.
Buildings, so far among the biggest energy consumers, are turning into
sources of energy. That is why their active participation in a Smart Grid
structure is essential for more energy efficiency, minimized operational
costs. Siemens technologies for metering, enhanced forecasting, and the
active management of a buildings energy consumption, generation, and
storage make possible this active participation in the power supply system.

A self-healing network thatdetects faults and corrects them
automatically: its real.
Getting a grip on the entire system
Power infeed from different sources into previously separated power
systems often calls for extraordinary power transmission and distribution
solutions. Despite the challenges this poses, however, the interconnection
of different regions, countries, or even continents remains a viable option
for providing certain areas with economical access to power.
As a solution provider with extensive experience throughout the entireenergy conversion chain, Siemens has already implemented a number
of projects linking power systems or connecting decentralized generating
units to the grid. In each case, conditions were unique. And because
Siemens makes a point of providing the customers with the most cost-
efficient results, the solutions, all based on various technologies, are
unique as well.
The intelligent, comprehensively proactive, and highly efficient properties
of a Smart Grid are based on a highly reliable power generation,
transmission, and distribution infrastructure, as well as consistent data
communication. The highest possible degree of proactive flexibility, as
well as stringent monitoring and control, comprehensive fault protection
and analysis, and maximal operational safety and security are of the
utmost importance when it comes to fully bringing to bear all strengthsand capabilities of the Smart Grid.

After a long day you decide to relax on
the couch. You start reading a magazine
on new technology and constant
innovations in energy networks. Smart
Grids can now detect and repair faults
before they can ever turn into a problem.
Just this morning you were talking to a
business partner who wanted to turn his
power plant structure into a self-healing
network. Five years ago you would have
answered: Dream on! this morning
you asked: What are you waiting for?
You ponder that the energy world is
developing at amazing speed, while a
thunderstorm is rumbling outside your
living room window. A pretty good
feeling, knowing everything will be fine,
even if the worst possible thunderstorm
strikes the middle of the city.

Reduction in transmission losses increase in system security
Technologies from Siemens such as high-voltage direct current (HVDC)
transmission and flexible AC transmission systems (FACTS) help connect
large-scale wind, hydro, and solar power generation to the grid even
when generation takes place hundreds, or even thousands, of kilometers
away from the centers of consumption.However, the constitutive element of the Smart Grid is state-of-the-art
communication. Siemens communications solutions enable online
monitoring and control of all grid assets, which in turn means fastest
possible reaction to faults and minimized downtimes. In many cases
intelligent substation automation and protection solutions in combination
with the Energy Management System (EMS) will even enable the Smart
Grid to react autonomously. Advanced condition monitoring solutions
from Siemens help optimize grid usage through continuous information
about the state of the devices in operation and high-quality evaluation for
minimized downtimes, reduced life cycle costs, and an extended service
life of the assets. Balancing technical and economic needs, the Siemens
Grid Asset Management Suite (GAMS), a modular and SOA-based solution,
additionally boosts the efficiency, transparency, and flexibility of gridasset management.
