Key issues in Global Electricity 14John Bower

Unresolved issuesState and Federal policy objectives are interdependent and often in conflict

LIBERALISATION CONFLICTS

Competition

• Profit motive of capital market versus public service obligations• Open access rights to transmission / distribution versus monopoly ownership• Competitive industry structure versus creation of national champions

Security

• Indigenous generation versus low cost imports• Generation fuel self sufficiency versus low cost imports• Managed bilateral trade versus reliance on transit routes through third countries

Environment

• Lower prices versus higher environmental taxes • Lowest cost technology (CCGT) versus renewables and nuclear• Regional benefit of cross-border transmission lines versus impact on local area

Speaker

John Bower is Senior Research Fellow at the Oxford Institute for Energy Studies. His research interest is in the emergence and evolution of cross-border electricity and gas markets. Specifically; the development of efficient pricing and investment mechanisms for transmission capacity, integration of energy markets, and energy price / credit risk management.

John’s previous career was in the commodity industry and 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. Before joining the PhD programme he was Global Controller Metals/Commodities at Deutsche Morgan Grenfell.

John completed his PhD at London Business School in 2000. He also has an MBA from London Business School and an MA in Biochemistry from Oxford University.
