A reader of my first article on geography and electricity prices pointed out that the fragility of the UK’s electricity system was highlighted by periods during 2024 when the cost of transmission from France to England accounted for more than one-half of the market value of the electricity.
Thank you Gordon for another embarrassment of riches. You, David Turver and Kathryn Porter have saved me wasting my time with mainstream media accounts of energy prices.
On a point of detail, I believe that in footnote [2], the second sentence should end with "HHV value".
Thank you for spotting the error. I have corrected it now. HHV and LHV definitions of calorific value are the source of huge - and often deliberate - confusion.
Thank you Gordon! I understand from my days working with domestic natural gas, that the two values correspond to what I knew as gross and net calorific value. Gross (HHV) was the total amount of heat generated by burning the gas, and Net (LHV) was what you got if you let the latent heat carried in the water vapour, escape. Yes, much confusion, including some folk quoting efficiencies of over 100% as a result!
