With the fleet sizing completed, the overall required electrical load can be calculated. The electrical team will then determine the required distribution and infrastructure. BBA can provide transmission solutions to our clients, including off-site interconnections and infrastructure.
A full cost analysis can be performed after each group has provided its design requirements. From here, multiple sensitivity analyses can be performed to ensure the best solution, or combination of solutions, is selected.
A good example: the Copper Mountain Mining Corporation (CMMC)
Based on its proposal to the provincial government, the Copper Mountain Mining Corporation (CMMC) has been selected to enter funding conversations under the CleanBC Industry Fund for this initiative.
BBA was mandated by CMMC to perform a low-carbon emission study. As part of the study, our team determined whether there were economic and environmental benefits to using trolley-assisted trucks for a segment of ramp at Copper Mountain Mine.
As a first step for the study, BBA had to determine the physical requirements for such a system. Since power lines and poles need to be installed on the ramp, the current haul ramp section needed to be reviewed. BBA’s scope included mining design changes to the ramp segment for the trolley-assist system, the civil and structural recommendations for the foundations and spacing of the poles and catenary system, the effect of the electrical distribution system, and electrical solutions based on increased power feed and supply requirements. BBA also provided design and recommendations for constructability, GHG emissions savings and completed the financial analysis for the project.
The study helped determine the overall GHG emissions reductions that could occur over an initial ten years, with hopes to extend the trolley-assist system to other parts of the operation in the long-term.
An experienced team!
Do you have a mine electrification project or GHG emission reduction targets to meet? Contact our team.
At BBA, we are members of BC Hydro’s Alliance of Energy Professionals. In addition to working with BC Hydro for many years and being a member of the energy alliance, we have experience in emissions reduction and mine electrification.
Our electrical engineers can help determine your distribution and transmission needs, while our mining engineers can create a safe and stable design in which your electric equipment can operate. Our mining engineers also create optimized mine designs to satisfy GHG emissions reduction requirements and to better connect to the electrical infrastructure.
