Will the lights stay on in Europe? Key issues for EU power systems(PPT)

摘要

1. Current European electricity markets are incomplete and do not send the right price signals: 1.1 Reforms of energy markets to reward flexibility and capacity mechanisms (CMs) are both needed and complementary 1.2 Drivers for implementation of CMs differ across member states and explain patchwork of approaches 1.3 One-size-fits-all approach unlikely to work and not necessary 2. Interaction of CM and energy market are misunderstood and largely overplayed: 2.1 Well designed CM will not affect bidding strategies in energy market, although change in generation mix will modify prices 2.2 Magnitude of potential effects is small compared to distortions associated with other public interventions (RES support, etc.) 3. Cross border participation in CMs raises complex issues: 3.1 Several approaches possible for explicit foreign participation with pros and cons 3.2 Need for a European framework to deal with situations of coincidental scarcity 4. Capacity mechanisms are only a stepping stone - long term market design challenges: 4.1 European power market model historically focussed on short term operational issues, focus needs to turn to investment incentives, risk hedging/sharing mechanisms , and coordination mechanisms for transmission, centralised and decentralised generation
