In 2016, 54% of our gross electricity demand was met by renewables from a total capacity of 8 662MWh or 8.6GWh (see graph above). That suggests our total demand is typically no more than 17 000MWh or 1.7GWh though this is falling. It fell by 15.4% to 2014 against a target fall of 12% by 2020. This is at least in part due to home improvements with 92% of Scottish homes now having at least 100mm of loft insulation installed.
Current supply (September 2017) is 9.7GWh and is projected to reach 21.3GWh before 2020 (see graph above). This suggests oversupply of at least 5GWh which can be exported. Though a relatively modest figure, it can be added to the overall energy exports from Scotland. 73% of all primary energy worth £16 billion is exported to rUK and beyond.
Remember ‘exports’ of energy to rUk are not included in Scotland’s already healthy, and unique in the UK, trade surplus figure.
Also, remember, the Herrod newspaper, in 2015, publishing this below?
‘Only those of a certain age can now remember candle-lit nights of the 1970s, so it is not surprising that Scots are complacent about “security of supply” – the assumption that the lights will always respond to a flick of the switch. That complacency may be set to change, at least to the extent that we may need to start thinking about importing power to keep the lights on’
Stop it, my sides hurt!
