British Columbia Hydro Dam Construction Project

Light Tower Rentals for a British Columbia Hydro Dam Construction Project

Project Scope

We deployed an initial 38 Solar Hybrid Light Tower fleet to a British Columbia dam construction project. This case study compiles data for all 38 units over a 12-month cycle.

Project Results

Throughout the 12 months, the units averaged only 4.7 hours of engine run time. The total cost savings using Cahill Solar Hybrid Light Towers ranged from $33,160/month to $98,778/month, depending on if you want to account for daily labour to turn on and off a conventional light tower. In this case, the rental rate the project was paying was $2,240/month/unit, and substantial monthly savings were still seen with Cahill Technology.

Benefits of Cahill Construction Solar Tower Rentals

Cahill offers three hybrid solar-powered light towers: the LLTT-H, LLTB-H, and the LLTT-H XL. These towers provide exceptionally low fuel consumption, enabling them to operate continuously for up to 35 days before requiring refuelling. Moreover, they require fewer refuelling intervals and oil changes than conventional light towers, reducing operational expenses and enhancing operational availability. Integrating the DSE 3G web interface + GPS module enables seamless real-time remote monitoring and control.

By harnessing hybrid technology, which merges solar energy with a DC generator, these light towers exemplify a strong commitment to environmental sustainability. They are well-suited for round-the-clock operations such as mining, oil & gas, and construction activities.
