Iberian electricity sector: background
• Scarcity of fossil fuels. • Energy production fundamentally based on water resources and fuel imports.
• External energy dependence. • Sector’s configuration was different in comparison with developed countries • Uncompetitive sector.
• Out-of-date and unable to sustain an increasing demand.

Iberian electricity sector: transition
EU reform aimed to a more competitive sector: • Prices can transmit the efficiency improvements to consumers
• Single market using regional electricity markets (MIBEL): spot – forward • There is still a high market concentration, especially in Portugal.

In short: • Process evaluation isn’t easy: different goals and different points of view
• Renewable deployment process vs economic growth and modernization: • GDP: some evidence, specifically for Spain and for capacity (wind) • Employment:
• Spain: wind • Portugal: biomass
• Innovation (Spain): increase in patents (wind and solar) • GDP, employment and innovation: negative effects of financial crises
• Future: • European and international agreements • National policy incentives • Problems:
• Electricity market: high prices, limited competition degree, consumers opinion,… • External dependence (and hydro dependence).
• …
