WP1 – Energy Audit

Identify and apply evaluation measures and technology, and establish possible on-site energy saving measures, monitoring their overall effectiveness. Infra-red Thermography will be utilised both before and after the intervention to assist with the identification of opportunities.

WP2 – Physical monitoring of Substations Energy Breakdown and Analysis

Assessment and data breakdown of substation sample. The loadings of each circuit will be individually monitored and examined. The ambient levels of heat and light in the substations will be monitored as part of this, with potential control strategies to be examined.

WP3 – Building Design Evaluation

The substation buildings with and without the potential energy saving measures will be modelled, considering what measures will be possible to carry out. This will allow the impact on load demand to be determined, while accounting for potential risks in the substation environment.

WP4 – Wider Substation Improvements

Taking learnings from the study of the three initial substations, a further 5 or 6 substations will be identified and analysed for their energy performance. These studies, while at a lower level of detail and with fewer energy saving measures implemented, will allow a wider study to evaluate the impact of the energy and cost savings, and the environmental benefits, on the wider SP Transmission network.

Benefits

WP1 – Energy Audit

The delivery of three reports showing the key measures which have delivered energy savings at each substation.

WP2 – Physical monitoring of Substations Energy Breakdown and Analysis

Production of a breakdown analysis of the loading at each of the identified substations, with an evaluation of possible energy control strategies.

WP3 – Building Design Evaluation

Production of a report which identifies points of improvement for the fabric of the substation buildings, with proposals for improving heating and lighting within the substations.

WP4 – Wider Substation Improvements

Production of a report showing the improvements which could be made across all transmission substations in the SPT Licence Area, quantifying the benefits of rolling out the changes across SPT.
