According to the Department for Business, Energy & industrial Strategy (BEIS), the total forecast expenditure as of April 30, 2019 was £907 million. This represents the amount of tariff payments the BEIS anticipate it is committed to, based on application data.
There will be no tariff reductions applied through degression on July 1, 2019 because none of the individual technology thresholds are exceeded. The next potential degressions will be applied on October 1, 2019.
