The Grid's overall capacity to handle an increased electricity load;
Delays in connecting new generation sources to the Grid.
As of June 2025, there was 0.7GW of pumped hydro and 0.5GW of battery storage in Scotland, with the CCC modelling a significant increase will be required, reaching 5GW by 2035.iiCCC, Scotland's Carbon Budgets, May 2025, pg 93
Opposition to infrastructure - New renewable developments; whether that is large turbines, pylons or substations and associated infrastructure like new tracks and the work to make them, can arouse opposition.
