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outdated energy infrastructure.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.

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.

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.
