Challenge
Chorus operate telecommunication sites right across New Zealand and had a goal of reducing costs and improving visibility
Solution
In 2015, ESP installed electrical sub-metering at 7 of Chorus’s core sites followed by Type 2 Energy Audit. This resulted in better energy use visibility and energy efficiency recommendations. In 2016, following the success of the initial work, ESP extended the retail metering rollout which allowed data from each of the 93 sites to be ingested into ESP’s advance data analytics platform. ESP have since then provided peak demand analysis, power use effectiveness tracking, energy alerts, regular steering group meetings to enable the asset managers to have complete visibility of their assets.
Outcome
The continuous energy efficiency engagement has resulted in a 16% reduction in energy usage since the start of the programme. ESP continues to work with Chorus to optimise energy and related costs at their sites.
