20GW of UK PV for 2020

Posted on

DECC has revised its estimate of PV’s large-scale ground-mounted deployment potential to March 2017 from 720MW to 4.6GW, a welcome acknowledgment of the case we put forward. Note however that DECC emphasises this is not a target, but a modelling assumption of the “maximum technical deployment potential of large-scale ground-mounted solar PV in the UK in this period”. From modelling undertaken with National Grid, DECC consider that 20 GW of solar PV (both large- and small-scale) is the theoretical technical maximum that can be accommodated on the grid by 2020.
