UPDATE. More about the function of the interconnections and the fragility of the British power system.
Britain’s electricity system is sufficiently fragile at certain times
of day that if one of the subsea “interconnectors” tripped while
importing at full capacity, it could trigger power cuts like those
of August 9.
Macron threatens to cut the interconnector to Britain.
Following the EU summit in Brussels on Friday, Mr Macron told French radio that if the UK does not allow French fishermen in its waters, the EU would have to block the UK’s energy supplies to the European market.
He suggested the right to fish in British waters was worth 650 million euros to EU fishermen, but that access to European energy markets was worth up to £2.3billion (€2.5bn) to the UK.
More research required. Britain imports power some of the time and is not a net exporter although this might happen if the offshore wind factories perform as expected (hollow laughter).
James Brabben, Wholesale Manager at Cornwall Insight, said: “Great Britain becoming a net exporter of power would be a real reversal of roles compared to the past decade. Our modelling of Great Britain and EU markets shows how convergence in the generation mix of power markets across Europe will see more volatile flows over interconnectors. Great Britain’s comparative advantage for offshore wind resources supports a vast build-out of the technology and could see greater flows of power to Europe as a result.
