A step-change in wind power deployment -from national models to international convergence? Joseph Szarka University of Bath
Published by Palgrave in 2007 Five nation comparison: Denmark, France, Germany, Spain, UK A technology whose viability and deployment is highly dependent on (national) framework conditions: - operational; - economic; - institutional; - social.
Introduction Wind power is now a highly diversified phenomenon Key variables: • size of turbines • size of wind farms • support mechanisms • investment and ownership patterns • industrial structures Consequences: • specific national and international development models • alternative development paths
Development models • The ‘Danish model’ - small-scale capitalism and local ownership, with utilities in the background. (Also characterises Germany) • The ‘Spanish model’ - large-scale capitalism and national ownership, with utilities in the foreground. • The ‘international utility model’ - large-scale capitalism and international ownership of wind farms in UK, USA etc. (Also global firms acquiring controlling interests in the wind power supply chain – GE, Siemens, Areva)
Development paths • Path 1. ‘Bulk power’ based on fossil and nuclear sources - centralised production, large scale facilities, major infrastructures, big corporations. • Path 2. ‘Tailored energy’ - RES & EE - decentralised production, ‘small’ scale facilities, matching of sources with uses, diversified ownership.
The step-change in wind power deployment involves: a change in scale – of installations a change in industrial structures – globalisation a change in public policies – but to what ends? • From small installations • To large wind farms • To offshore.
The UK – a prime example of upscaling and internationalisation

Denmark Current energy agreement until 2009 • – 2 x 200 MW offshore • – 350 MW in repowering onshore Market-based tender system ensure price competition • Horns Rev II: 200MW, 69.5 euro/MWh/50.000 hours • Nysted II: 200MW, 67 euro/MWh/50.000 hours Source: DWIA, 2006 • ‘Danish model’ stagnates: major growth is offshore
Germany • Onshore stagnation predicted some time ago. • Clear signs of slowdown in 2007 with 1,667MW added (decline of 25% on 2006). • Very ambitious, long-term plans for offshore: in the range of 41970 - 65922 MW. • Capital requirements are immense – large consortia only.

So what does the future hold? Source: VDMA (2006)
Convergence towards the ‘international utility model’ • The ‘Danish model’ has lost its dynamism in Denmark – offshore expansion brings the utilities back in. • The German pattern is following the same trends – but writ larger. • The ‘Spanish model’ can continue in a largely protected Spanish market; beyond Spain, the Spanish utilities are key players in the internationalisation of the sector. • The UK ESI is dominated by foreign utilities (EdF, EON, RWE) and Iberdrola has taken over ScottishPower. • In each case, the role of international consortia is becoming preponderant (bringing together manufacturers, utilities, financial institutions and sometimes energy majors). • This is the extended meaning of the expression ‘international utility model’.
Linking scale of wind power deployment with investment and ownership models
Summary and interim conclusions • The phenomenon known as wind power has changed and continues to change as we observe it. • A step-change is taking place from Path 2. ‘Tailored energy’ (community ownership, embedded generation) to Path 1. ‘Bulk power’ (centralised production, large scale facilities, major infrastructures, big corporations) • Discussion point: arguably a need for BOTH paths, but to get both, we need to move from current bias towards Path 1 (especially in the UK) to a genuine commitment to Path 2.
Ways forward for the seminar series Our analyses need to connect with those changes – to look to the future, not to the past – to investigate not just path 2, but also path 1 – to consider how both paths can co-evolve. We need to draw the consequences in terms of: • Public policies – support mechanisms • Market regulation • Planning issues • Investment, ownership and stake-holding • Social acceptability And make recommendations for best practice in each area.
