Hornsea Project Three Offshore Wind Farm

Received 30 June 2018
From Michael Wright


Although in general I would support such additions to our essential national infrastructure, I wanted to ask a few questions about the resilience being designed into, and operationally planned for, this important energy supply system.

In a recent Economist article on electrical infrastructure resilience (The Economist, July 15th – 21st 2017, page 16, A Flash in the sky), the vulnerability of electricity infrastructure to geomagnetic storms is discussed along with possible civilian life consequences. As the article states, it is a low probability event but with high consequence.
However, if one adds to this the higher probability (but maybe lower consequence) of unwelcome events such as destructive terrorism and cyber-attack, then the overall resilience strategy addressing issues for example of access control, surge blockers, electro-magnetic pulse protection and insurance spares, becomes very important.

I am not expecting to be told the details of any such strategy, but it would be re-assuring to know if there is indeed a strategy and that it addresses all these risks and mitigations.

Some information about myself. Although now retired, I worked for 40 years in the oil and gas industry (with a short spell at Sizewell B in the 1980’s), mostly on development projects, including some at key onshore gas reception facilities where security has had to become considerably more robust over that time.
