ENWL034 - Cool Runnings NIA
“Variable rating” is a new tool being developed in Cool Runnings to provide near real-time ratings for distribution transformers that vary with ambient temperature and substation environment. As the variable rating will be higher in cooler ambient conditions, additional capacity can be released in winter when it is anticipated that the electrified heating load will be at its peak. Therefore, this tool is specifically suited to managing the increased demand associated with HPs.
This tool will be implemented in stages to ensure the successful transitioning of the method for BAU implementation. This project will cover the initial mobilisation and enablement works for the lab testing of distribution transformers. This includes test design, Variable Rating Methodology development and initial scoping of tools and process changes.
Timescale: October 2025 - April 2026
