Europe I 8John Bower
The Directive and retail supply competitionThe Directive guarantees competition in supply with transmission / distribution access.
KEY PROVISIONS OF THE ELECTRICITY DIRECTIVE
• Unbundling of accounts– Prevents subsidisation and distortion of competition in vertically integrated firms
• Competition in construction and operation of new plant– Authorisation procedure allows market to determine investment criteria – Tendering procedure allows central planner to determine when/where to build capacity
• Open access to transmission (and distribution) networks– Independent Transmission System Operator (TSO) must be appointed– Tariffs for connection and carriage must be transparent and non-discriminatory– Reciprocity clause and system reliability issues allows countries to bar access
• Right of consumers to choose their supplier– Increasing number of consumers should be authorised to choose their suppliers

Europe I 11John Bower
Unresolved regulatory issuesIn reality State and Federal policy objectives are interdependent and often in conflict
LIBERALISATION CONFLICTS
• Security
– Concern about dependence on other countries for generation capacity– Concern about dependence on other countries for generation fuels– Concern about dependence on other countries for gas / electricity transmission routes
• Competition
– Conflict between capital market and public service obligations– Access rights to transmission/ distribution and pricing of transmission– Increasing industry concentration through mergers and acquisitions
• Environment
– EUETS (CO2) and LCPD (NOx, SOX, particulate) costs versus lower prices– Renewables versus Combined Cycle Gas Turbines (CCGT)– NIMBY delays on approval of transmission routes / generation site licences

Speaker
John Bower is a Senior Research Fellow at the Oxford Institute for Energy Studies which is an independent research charity affiliated to Oxford University and dedicated to advanced research in the social science aspects of energy. John joined OIES in November 2001 and his research interest is in the emergence and evolution of integrated cross-border electricity and gas markets. Specifically; the development of efficient pricing and investment mechanisms for energy, transmission capacity, and emissions.
Before joining the OIES, John completed his PhD at London Business School and his previous career was in the commodity industry. His experience ranges from energy trading, at Marc Rich & Co, to risk management consultancy, with Coopers & Lybrand, advising commodity traders, producers and processors in base metal, precious metal, ‘softs’ and energy markets. Immediately prior to his PhD he was Global Controller Metals/Commodities at Deutsche Morgan Grenfell.
