Electrical Energy is the Backbone of today's and tomorrow's Society



Challenges for Electrical Power Transmission and Distribution

Urbanization

Scarcity of Natural Resources

Environmental Awareness

Need for more Energy

Open Markets

Capacity Increase and Bulk Power Transmission over long Distances

Increased Use of Distributed and Renewable Energy Resources

Distribution within congested Areas / Megacities

Goal: reliable, flexible, safe and secure Grids



*) ICT = Information and Communication Technologies

Electrification of society

“Age of Coal”

“Generation and load closely coordinated”

Supply island withstochastic load

Extensive generation of electrical energy

”Age of fossil fuels”

“Generation follows load”Integrated network, central

generation, load stochastically predictable, unidirectional energy flow

Coalhydro

Coal, gas, oil,hydro, nuclear

No environmental concerns

19th Century 20th Century

Shift to New Electricity Age Challenges require rethinking:

1.) Demographic change 2.) Scarce resources 3.) Climate change

“Energy system shifting”Increasingly decentralized,

fluctuating generation“consumer” becoming “prosumer”

Coal, gas, oil,hydro, nuclear,

biomass, wind, solar

Environmental awareness

Unsustainable energy system

The New Electricity AgeElectricity will be the energy source with a power grid as

backbone.

Integrated energy system

“Load follows generation”Central + decentralized generation,

intelligence with ICT*,bi-directional energy flow

Renewable energy sources (solar, wind, hydro, biomass),

“clean” coal, gas, nuclear

Siemens has a commitment in the DESERTEC Industrial Initiative (DESERTEC II). The objective of this initiative is to develop over the mid-term a technical and economic concept for solar power from Africa. Work will also focus on the clarification of legal and political issues.
