Developed industrial economies should not be at risk of power blackouts in any but the most extreme and exceptional circumstances. The ability to anticipate demand and to put in place spare capacity may not be available to the poorest economies of sub Saharan Africa but it is certainly available in the UK. The risks of a tightening balance of capacity and demand have been obvious and widely discussed for at least the past three years. To have reached the point where National Grid are having to issue warnings and to tell some consumers that they will have to agree contracts which allow the supplies they need to be interrupted because of potential shortages of supply is shameful.
