Mine Power Plant

Kuna provided comprehensive engineering services for multiple projects within the power plant infrastructure of an existing mine. The mine operates its own power generation and distribution system, supplying electricity across the entire site. Kuna’s involvement spanned a range of projects, including electrical system analysis, electrical distribution, heat rejection, and combined heat and power plant operation.

For electrical engineering, Kuna led an arc flash analysis of the mine’s 480-Volt electrical system. This project required verifying all electrical wiring sizes and lengths, breaker and fuse ratings, as well as trip settings and electrical equipment configurations. As part of this work, all 480V single line diagrams were updated to provide the mine with accurate, up-to-date system drawings. This effort followed a previous electrical load study that assessed the system’s capacity to generate and distribute power across the site.

On the mechanical engineering side, Kuna evaluated the mine’s combined heat and power system to address the need for additional heat rejection due to increased power generation. The project began with process diagrams and P&ID development to explore debottlenecking opportunities. Through a detailed analysis, Kuna identified cost-effective solutions that had previously been overlooked, providing innovative recommendations for system optimization. This work transitioned into detailed design and construction support for new pumps, heat exchangers, and control systems in the power plant.

Kuna’s extensive work within the power plant highlights the team’s ability to thoroughly understand complex systems and apply technical expertise to develop innovative engineering solutions. Kuna’s practical approach to design development, paired with deep local knowledge, allows for tailored solutions that meet the unique needs of each project.
