Britain's onshore wind developers are set to install at least 1.2GW of new capacity next year, with more than 50 projects going fully operational. 

This is more than three times the capacity installed in 2015, when just over 400MW came online.

RenewableUK says uncertainty over future access to the energy market means that onshore wind developers are trying to get projects up and running before current arrangements end in 2016.
