The Changing Face of UK Power Supply

There are four main points to me made from this post:

1) Dispatchable capacity in the UK has declined 2.1GW since 2004 which is not a material difference since electricity demand has also fallen in that period.
2) The nameplate capacity margin is approximately 13 GW which seems ample contingency for plant outages. Increasing this margin would involve paying companies to keep higher unused capacity in reserve.
3) The risk of capacity failure is always around 6pm on a weekday in winter and only lasts for a few hours each day.
4) 13.5 GW of wind and 7 GW of solar cannot be relied upon to provide any supply at 6 pm on a winter week day when the blackout risk is greatest. Continue reading
