2. European energy policy Renewables to play a key role
EU Energy Directive
Horizon: 2020
Germany
National energy concept
Transition horizon: 2050
Meet growing energy demand
20% more energy efficiency
0% nuclear
Minimize environmental impact
20% renewables
80% renewables
20% less CO2-emissions
80% less CO2 emissions

4. The transmission grid becomes increasingly important Continued development of AC and DC technologies
Traditional overhead line with AC
Overhead AC line with FACTS
HVDC (high voltage direct current) Classic overhead line
Underground line with HVDC Light or AC cable
Different technologies: Same power transmitted
Capacity up 10x, losses down from 3% to 1% per converter station since 2000

7. Balance renewable power with low climate impact HVDC limitation today - point to point power highways only
Solving a hundred year old technology puzzle
To avoid total blackouts due to faults in the DC
Grid …
… very fast separation of faulty lines required
The Hybrid DC Breaker
was the missing link !!! x x

8. Bipole configuration of HVDC Light (320 kV) Layout with Hybrid HVDC Breaker

9. Hybrid HVDC Breaker – Basic Functionality Reduction of transfer losses from typical 3MW to 30kW
Normal operation: Current flows in low-loss main branch
Proactive control: Load commutation switch commutates current into Main Breaker, the Ultrafast Disconnector opens with very low voltage stress
Fault clearance: Main Breaker switch commutates fault current into arrester bank

11. Enabling the next generation grid
The Hybrid DC Breaker enables large scale integration and transmission of renewable power
DC Grids provide power transmission in a highly efficient and stable way, up to 50% more efficient compared to AC systems
Critical technology for European grid visions
Interesting business opportunity for ABB in mid- to long term
Renewable energy is very important to CO2 reduction and significant new renewable capacity is planned
Under the New Policies Scenario of the IEA (which assumes that recent government policy commitments will be implemented in a cautious manner), most of the renewable capacity built out over the coming 20+ years will be wind (40%), then hydro (26%), solar (24%) and then other (10%, which is mostly biomass and waste, but also a little geothermal and marine).
Most of the build out of renewable capacity is forecast to be in Europe and the US (mostly Europe), China and India. Still some significant developments in South America and the Middle East & Africa
