To ask the Scottish Government what assessment it has made of how the total cost of the Renewables Obligation is expected to change over the next (a) five and (b) 10 years.
While the Scottish Government is responsible for the legislation underpinning the Renewables Obligation Scotland (ROS), Ofgem are responsible for the operation and administration of the scheme and consequently hold the operational and administrative data.
To date, the Scottish Government has not carried out any formal analysis of how the total cost of the ROS is expected to change over the next 5 or 10 years. However, it is expected that the total cost of the scheme will steadily reduce between 2027, when the first generators begin leaving the scheme, and 2037 when the scheme closes.
