The world is changing – How to ensure a reliable,
ecological and affordable energy supply?
Demographic dynamics
Scarce resources
Climate change
■ Population growth
7.5 bill. in 2020 (+1.1 bill.)
■ Megacities (>10 mill. people)
27 megacities by 2025
■ Geopolitics
70% of global oil and gas
reserves are located in just
a few countries
■ Oil price fluctuations
■ Climate goals
Political programs aimed at
long-term reduction in
CO2 emissions

Today’s Grid
Before
 One-way limited communication
 Few sensors and analog control
 One-way power flow
 Little to no consumer choice
 No electric vehicles
 Reactive maintenance
 Centralized generation
 Limited usage transparency

 The growing demand is
stretching the US's power
grid to it's limit.

Increasingly distributed generation
 The grid's infrastructure was
not intended for power to flow
bi-directionally.

Infrastructure Reliability & Security
 T&D equipment is built to last
40 years  The average age
of U.S. T&D equipment is 42
years.
 Blackouts cost Americans an
estimated $150 billion/year.
Millions of eCars
 Without innovation, ~160 new
US power plants will need to be
built by 2020 to support eCar
adoption.

Tomorrow's Grid
 Bi-directional communication
and metering
 Bi-directional power flow
 Pervasive monitoring and digital control
 Self-monitoring & high visibility
 Many consumer choices
 Millions of electric vehicles
 Condition-based maintenance
 Applications
 Proliferation of numerous applications

Tomorrow's Smart Grid Enables Flexibility …
Opportunities for Siemens (2/2)
Infrastructure Reliability & Security
 Smart Grid will drastically
reduce blackouts by enabling
a "self healing" grid.
Millions of eCars
 Smart Grid innovation has the
potential to dramatically reduce
the need for new power plants
to be built by using "smart
charging."

Why Should I care about the Smart Grid?
The cost of building a Smart Grid in the United States will be $165 billion over the next
two decades, or $8 billion per year.
Electricity prices have increased by 54% in the last decade.
A 5% drop in peak-energy demand would eliminate the need for 625 peaker plants in the United
States – an annual $3 billion savings.
One typical electric-drive vehicle can put out over 10 kW, the average draw of 10 houses.
It will create business opportunities (like the internet did)
Smart Grid will create roughly 280,000 new jobs in the U.S. over the next four years.

Electric Vehicle Infrastructure in the US
eMobility:
Smart Grids will bring
eCars to start.
Charging periods will be reduced and electricity
will become cheaper.
Millions of eCars will depend on grids as
consumers, and also serve as storage units.
A new power infrastructure has to be constructed:
charging units, public charging stations, eParking
garages, battery sweeping stations.
eCars will stabilize the grid as mobile energy
storage units and counteract power failures
caused by fluctuation.

 EVs will initially be launched
in specific states
 Expect nearly 750K EVs
by 2015 and over 1.1M
EVSE units
 We consequently expect
higher concentrations of
EVSE in these states
 Utilities must implement
infrastructure now to support
the increased power
demand caused by EVs
