Proposals for a new double circuit 275kV line
Since the summer of 2014 we have been developing proposals for a new double circuit, 275kV line that would reinforce the network to the north of Beauly.
As part of our licence responsibilities, we are required to continually assess the amount of forecast generation seeking to connect onto the network to ensure the proposed reinforcements are still the most efficient and cost effective solution. Along with National Grid, who operate the transmission network in Great Britain, we have carried out a number of studies including assessing the impact of:
- Changes in the forecast generation - New wind farm developments can request a connection or existing developments can modify their capacity or even withdraw completely.
- Government initiatives and subsidies, most relevantly, for renewable incentives can change leading to changes in the forecast generation
A Cost Benefit Analysis (CBA) which compares the costs associated with developing and implementing the project, with the benefits this would provide to system capacity, and reduced operating costs. This ensures that consumers (who pay for this expenditure) are getting value for money
In light of the most recent assessments, we feel that it is right to postpone development of the current project pending further ongoing assessment.
As part of this further assessment, we will continue to review the need and timing for a range of alternative reinforcement options and will continue to work with National Grid to identify the most economic proposals to advance. Potential alternatives may include:
- Examine the existing and developing network to identify any available spare capacity
- Increasing the capacity of the existing network by the use of higher capacity conductors
- Consider new technologies such as high temperature conductors
- Review all options considered in the early development stages of the Beauly – Loch Buidhe project to gauge their potential effectiveness under the prevailing generation and demand background.
We remain committed to engaging with statutory authorities, landowners and communities on any potential developments at the earliest opportunity and would like to extend thanks to those who provided feedback on the Beauly – Loch Buidhe Project to date.
