Nuclear Prices Itself Out Of The Market — Graph

Originally published on RenewEconomy

The extent to which nuclear is being priced out of electricity markets has finally been revealed by the pricing mechanism unveiled by the British government in the deal to subsidise the Hinkley C nuclear.

The UK government will pay £92.5 for each megawatt hour produced from hinkley ($A154/MWh), around double the prevailing market price. This is after the UK supplied a loan guarantee for 65 per cent of the estimated $24 billion capital cost. The “strike price” – a fancy name for a feed in tariff – also has an escalator to take into account the impact of inflation, so the cost will rise in coming years.

So how does this compare with rival clean energy technologies? Pretty badly as it turns out.

This graph below, published by Craig Morris in Renewable Energy World reveals that the rates that will be offered for new nuclear from 2023 in the UK are far above what solar and wind currently cost. And, as Morris points out, the rates for solar and wind will go down by then, not up! Even offshore wind is getting £95/MWh from 2018 in the UK, but only for 15 years and without any loan guarantees.

This second graph below is even more interesting. It takes into account all the expensive PV that was installed with really high feed in tariffs at the start of Germany’s energy transition before the price of solar fell dramatically. From 2023, when the Hinkley reactor is due to be switched on, nuclear at this price still fairs poorly, and as the cost of those tariffs continue to decline, the cost of nuclear will continue to rise. It’s probably as good an illustration as any as to why Germany are not interested in new nuclear power station, and few countries are.
