Lessons from electricity liberalisation in the US and elsewhere: perspectives for Europe Richard Green Institute for Energy Research and Policy
Circumstances of this talk • I gave this talk in place of one that Professor Paul Joskow of MIT had been scheduled to give, but was unable to, and adopted his title • I have drawn heavily on his recent paper, “Markets for Power in the United States: An Interim Assessment”, Energy Journal 2006 • I have also benefited from talking with Paul and attending many of his presentations over the years • Paul should not be held responsible in any way for my choice of material to extract, or my conclusions
The Liberalisation Buffet • Entry into generation • Wholesale market with competition • Transmission system independence • Retail competition
Electricity markets • 1983 – a radical idea! • 1988 – UK government policy • 1978 – Chilean government policy • 1996 – European Union policy
Electricity in the US • Large, diverse, industry • Investor-owned utilities, State-regulated • Municipal and Cooperative bodies • Federal Power Authorities • Federal Energy Regulatory Commission • Power Pools • After PURPA (1978): NUGs and IPPs
US electricity markets States with active restructuring, Feb 2003; EIA
US electricity prices 12-14 c/kWh 10-12 c/kWh 8-10 c/kWh 6-8 c/kWh 4-6 c/kWh Average residential rate, Jan 1998; EIA

What has happened? • Transmission: • Most utilities have tariffs for other users • Many Independent System Operators • Retail markets: • Least popular measure, low switching rates • Wholesale markets: • Half generation capacity is covered
How did they get there? • Transmission open access: • Pressure from FERC • Orders 888, 889, 2000 • Retail competition: • State initiatives • Wholesale markets: • State initiatives and evolution of Pools • FERC pressure beaten back
Standard Market Design • Bilateral trading for most power • Centralised auction for real-time power • “Bid-based, security-constrained, dispatch” • Price at each node equals the marginal cost of meeting more load there • Nodal price differences are the payment to transmit power (including bilateral deals)
Where are there problems? • Transmission: • Congested system, insufficient investment, “seams issues”
Where are there problems? • Transmission: • Congested system, insufficient investment, “seams issues” • Retail: • Customers don’t switch unless they save • Need to allow competitors to make money
Where might there be? • Market power: • Mechanisms are in place to limit price spikes • Generation capacity: • Lots of new entry around 2000 • Lots of bankruptcies soon afterwards • Capacity markets: • Designed to raise the “missing money”
What about Europe? • Large, diverse, industry • Large multinational companies • Small local companies • Member State regulation • Some informal coordination • European Commission
Where have we got to? • Legal unbundling • Power markets in most Member States • FERC’s Standard Market Design is nowhere to be seen • Balancing often done by incumbents • Retail competition for all consumers coming very soon!
Market power • EU Sector inquiry: evidence of problems • Wholesale markets concentrated • Most markets national in scope, not integrated • Vertical foreclosure via integration • Wholesale markets not transparent • Users don’t trust complex price formation
Market power remedies • Change the structure? • Change the rules? • Revenue Equivalence Theorem

Market power remedies • Change the structure? • Change the rules? • Revenue Equivalence Theorem • Change the size of the market? ½ + ½ = ¼ + ¼ • Are the markets joining together anyway?

How to ease congestion? • Build more lines? • Make “minor” investments? • Improve operating procedures? • Integrate markets better? • Balancing regimes, nomination rules, timing

How to ease congestion? • Build more lines? • Make “minor” investments? • Improve operating procedures? • Integrate markets better? • Balancing regimes, nomination rules, timing • Adopt trans-national markets?
A last word • “Electricity restructuring …is likely to involve both costs and benefits. If the restructuring is done right…the benefits … can significantly outweigh the costs. But the jury is still out on whether policymakers have the will to implement the necessary reforms effectively” (Joskow, 1997) • “I believe that statement continues to be true today.” (Joskow, 2006)
