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

National Grid Future Energy Scenarios
(2017)
Two Degrees 77 62 55 Cost optimal pathway to meet the UK’s 2050
carbon emissions reduction target.
Slow Progression 74 67 59 Low economic growth and affordability. With limited money, the focus is on cost efficient
longer-term environmental policies.
Steady State 77 88 81 Business as usual prevails and the focus is on ensuring security of supply at a low cost for
consumers. The least green scenario.
Consumer Power 80 89 81 High affordability, with no new targets
introduced, focus on consumer’s desires.
BEIS EEP (2016)[1]
Reference Scenario 74 68 65
Based on central assumptions of growth and fossil fuel prices. Contains all agreed policies
where decisions on policy design are sufficiently advanced to allow robust estimates of impact.
Low Prices 87 101 110 Assumptions similar to reference scenario but
using low fossil fuel price assumptions
High Prices 69 66 62 Assumptions similar to reference scenario but
using high fossil fuel price assumptions
Low Growth 74 67 64 Assumptions similar to reference scenario but
using low economic growth assumptions
High Growth 74 68 65 Assumptions similar to reference scenario but
using high economic growth assumptions
Existing Policies 75 77 78 Based on central estimates of price and
economic growth, but not planned policies.
Baseline Policies 87 101 110
Based on central price and growth assumptions, but excludes the impact of Climate Change
policies brought in since the 2007 Low Carbon Transition Plan.
