Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government, in relation to electricity costs, what they estimate the percentage increase will be for Balancing Services Use of System charges between (1) now and 2020, and (2) now and 2030; and what proportion of these increases will be attributable to efforts to connect renewable energy sources to the national grid.

Transmission, distribution and balancing charges are set by network companies in line with the charging methodologies approved by Ofgem, as the independent regulator.

Network companies also produce some future estimates of these charges. These include National Grid’s forecasts of Transmission Network Use of System charges for 2018/19 to 2021/22 (available at: http://www2.nationalgrid.com/UK/Industry-information/System-charges/Electricity-transmission/Approval-conditions/Condition-5/) and Balancing Services Use of System charges to 2018/19 (available at: http://www2.nationalgrid.com/UK/Industry-information/Electricity-transmission-operational-data/Report-explorer/Services-Reports/). These forecasts are not broken down to show renewable energy sources.
