In the latest auction with the UK government, offshore wind energy developers offered prices as low as £57.50 per megawatt hour (MWh). Hinkley Point C (Costly?) was guaranteed £92.50 MWh but this is inflation-linked as is already closer to £100/MWh. This guarantee also stands for 35 years. A very bad deal indeed for the UK consumer but not for us given that we must surely break away long before 35 years have passed.
In 2015, offshore wind power schemes required subsidies resulting in costs of around £117/MWh. This is dramatic evidence of the rapid development of the technology including larger more powerful turbines and now puts wind power way ahead of all other energy production methods in terms of cost to the consumer as well as to the environment. Keep in mind also, these are still early days for renewable technologies compared to competing technologies such as nuclear which can only become more expensive as safety fears intensify.
