Reducing emissions through hybrid energy solutions

At Glenmor Yard, part of the Fort Augustus to Ardmore overhead line project, a reliable power supply was needed for a remote site while reducing reliance on diesel. With a mains electricity connection subject to a lead time of more than 18 months and variable power demands across the site, an interim solution was needed to maintain operational resilience. 

To address this, the project team worked with Sunbelt Rentals to install hybrid energy systems across the site. A battery-diesel hybrid generator powered the main office, while a solar hybrid system was installed at the security cabin.  

The security unit includes 36 kilowatt‑hours of battery storage and 2 kilowatts of solar capacity, reducing fuel use and emissions by up to 70% compared with a conventional diesel generator. Continuous monitoring of load profiles enabled further optimisation, reducing generator run-time while maintaining reliable power. 

As a result, the project saved 34,990 litres of fuel, avoided 99 tonnes of carbon dioxide and reduced nitrogen oxide emissions by 551 kilograms, demonstrating how hybrid solutions can cut emissions while supporting reliable site operations.
