Offshore Wind • Offshore wind is already a major part of our energy supply, and key to our future • UK market is the largest in the world - and will remain so to 2020 and beyond • We have a strong framework to drive investment in offshore wind – delivered through Electricity Market Reform • We are already securing the economic benefits – and the potential is huge • The UK is at the forefront of delivering cost reductions in offshore wind – reflected in reduced “strike prices” over the decade • Some rationalisation of the “pipeline” of projects is to be expected – a sign of the sector maturing
