History of the Internal Electricity Market
●1986 European Single Act●1996: the first directive is adopted (after 8
years of discussions, a record)●2003: second package with new directive
(repealing the previous one) and a new regulation for cross-border exchanges. Plus ERGEG (European regulators group)
●2009: third package with new directive and regulation (repealing the previous ones)

OBJECTIVES OF ENERGY PACKAGES
●Create competition for the industry and the consumers
● Improve the liquidity of the markets
An open market integrated and competitive

EC Regulation in force from 15 May on European infrastructure priorities
● Priority limited to 12 strategic trans-European corridors and areas
● Rules to identify projects of EU interest ● Harmonised cost benefit analysis● Coordination of cross-border investments
approval process● Conditions for eligibility of projects of EU
interest

Phase 0 – 2015-2020
Phase 1 – 2020+

Policy and Regulation
Supergrid requires:– a new and stable community-wide
regulatory framework backed-up by strong political support.
– a full top-down EU approach planning methodology.
– risk adjusted returns to attract substantial investment.

New policy and regulatory aspects needed●2050 Supergrid design now: develop in phases
●One operator in future: a European ISO?
●EU grid codes●One regulator●Ownership: TSOs and
investors
Possible Regulatory hints for the future Supergrid

Recent Key DevelopmentsTechnical landmarks during 2012
● DC current interruption enable planning of the HVDC Supergrid now. Building blocks
– Hybrid HVDC Breaker and Half bridges– Full bridge with fast switches
● Capacity increase in cable factories, ships, production and engineering facilities are announced
– Gearing up for anticipated larger future volumes
● The number of interconnection and embedded HVDC links in construction increases rapidly with higher power ratings
– E.g. South-West link SE, EWIP IR-UK, INELFE FR-ES, Western link UK
● FOSG technology members spend every year around 4% of their turnover on R&D: large part on transmission

Meshed HVDC Grid system Here breakers are needed to isolate faults on the DC side from the remaining healthy parts
16
In a future power network with a high density of DC converter station it is logical to connect them also on the DC side to have a combined AC and DC transmission grid

The Hybrid HVDC BreakerAnnounced in Nov 2012
● Selected by MIT Technology Review as one of ten breakthrough technologies 2012. “The high power breaker makes the HVDC power grids practical. ... The Supergrid is a key to sustainable economic growth”
● The Hybrid path enables a dramatic reduction in losses and operation below 5 millisecond
● Also available as a pure semi-conductor design with breaking operation below 1 millisecond, but with higher losses
