The following table is taken from Mott Macdonald (2010) and gives levelised cost estimates (average generation cost per megawatt-hour) for new build plants in the main large-scale electricity generation technologies in the UK, including onshore wind, offshore wind and nuclear, at current engineering, procurement and construction (EPC) contract prices.
|Table 1: Mott Macdonald (2010) levelised costs (Case 1: 10% discount rate, 2009 project start at today's EPC prices, with mixed FOAK/NOAK)|

It should be noted that for the purposes of presentation, the table only gives either 'FOAK' (first-of-a-kind) prices or 'NOAK' (nth-of-a-kind) prices for each technology. On offshore wind, for example, it shows offshore wind 'FOAK' prices, whereas the round 2 technology may be considered to have progressed towards 'NOAK' prices. Mott Macdonald estimate 'NOAK' offshore wind costs at £125/MWh (10% discount rate, 2009 project start at today's EPC prices).
