Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government whether they will ensure that surplus energy generated by solar panels on roofs of warehouses and other commercial buildings can be exported back to the grid.

Generation from rooftop solar can be exported to the grid provided there is capacity to accommodate it. This may require investment in distribution and/or transmission networks. Ofgem has raised the threshold for generation connection projects requiring a transmission network impact assessment from 1 Megawatt to below 5 Megawatts in England and Wales. This will reduce connection timescales and costs for rooftop solar schemes previously above the threshold. Reform of the transmission connections process will facilitate connections for projects that remain above the threshold, provided they are progressing and align with the Clean Power 2030 Action Plan.
