    +1,542 GWh more of renewable energy electricity generated in Scotland 2018 than in 2017. (Source BEIS ET_6.1)

    +11,511 GWh more net electricity exports in 2018 (provisionally) than in 2017. (Source BEIS ET_5.6)

    Where did the 11,511 – 1,542 = +9,969 GWh come from in 2018 or where did -9,969 GWh get lost in 2017?

    Was there in 2018 +9,969 GWh additional generation from fossil fuels or nuclear?
    Did Scots in 2018 consume -9,969 GWh less?
    Did the grid in 2018 not lose -9,969 GWh that was lost from inefficiency in 2017?
    Was there in 2018 or some combination of the three possibilities?

    I haven’t found the statistics for Scotland 2018 which would explain this mystery +9,969 GWh fully as yet – generation for ALL fuels types, consumption and losses.

    The “Highlights” sheet in BEIS ET_5.6 identifies the Western HVDC link becoming operational without fully explaining the mystery +9,969 GWh.

    “Record net transfers from Scotland to England

    Net electricity transfers from Scotland to England reached a record high of 23.7 TWh in 2018, increasing 67 per cent on 2015’s record and 82 per cent on 2017. This means that net transfers from Scotland were higher than the UK’s total net imports from Europe for the first time since 2011. Transfers from Scotland to England were higher than 2017 for all quarters in 2018; however, transfers in Q4 2018 were exceptionally high after the Western HVDC link with Scotland came into full operation in October2.

    New Scottish interconnector pushes net transfers with Scotland to highest ever level

    Net electricity transfers between Scotland and England in Q4 2018 increased 44 per cent compared to Q4 2017, to reach its highest ever level at 7.0 TWh. This came despite the highest transfers from England to Scotland since Q1 2005, as transfers from Scotland rose more than 50 per cent. This comes after the 2200 MW Western HVDC link with Scotland entered full operation in October 20182. It is also likely that increased Scottish wind generation compared to the same period in 2017 added to the particularly high transfers over the quarter.”
