Cahill Solar Hybrid Light Tower Case Study: Emissions & Cost Reductions
Project Scope & Requirements
The Nutrien Joffre Nitrogen facility is located in Alberta, Canada. The Joffre operations are widespread and cover a lot of land. A lot of machinery is located outside, therefore lighting the operation requires robust lighting solutions. To solve the outdoor lighting concerns, the Nutrien team deployed 5 Cahill Solar Hybrid Light Towers.
Nutrien takes advantage of the increased hours of sunlight in the summer months to complete the site’s turnaround operations. The additional summer sunlight further helps charge the solar batteries. Additionally, the warmer summer temperatures allow the batteries to maintain their charge for longer periods. The annual turnaround involves scheduled maintenance and upgrades to improve site safety and efficiencies.
Project Goal: Reduced Carbon Footprint
Nutrien is always looking for opportunities to reduce and minimize scope 1 emissions. Operating in northern Canadian climates presents many hurdles for emission-saving initiatives due to extreme cold weather. Therefore, Nutrien proudly embraces any opportunity to reduce their carbon footprint.
Direct Environmental Benefits:
- Reduced direct fuel consumption
- Lowered refuelling frequency
- Reduce fuel spill risk
