Power System Design That Gets Built, Not Just Drawn<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Power system design for mining involves the full electrical engineering scope from site load analysis and concept through to detailed design documents, protection coordination studies, and commissioning test packs the complete technical foundation a power station needs before a single cable is pulled.<\/p>

At Silverstone, that design work is done by the same engineering team that commissions the finished station. We design for WA mining conditions, Pilbara heat loads, Goldfields logistics, remote site access constraints, and the compliance requirements of HV systems operating under Western Power and Horizon Power network rules. Our designs don’t get handed to a separate construction contractor to figure out on site.<\/p>

We design diesel power stations, hybrid solar-diesel systems, BESS-integrated generation, and underground HV installations. Our scope includes both LV systems (415V) and HV systems up to 33kV, protection relay coordination, earthing system design, and full commissioning documentation to AS\/NZS standards.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

How We Approach Power System Design<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Every power system design project starts from the same question: what does this site actually need to run reliably? Everything else follows from the answer.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

\n\t\t\t\t\t

Site Assessment & Load Study<\/h3>

Before any design work starts, we assess the site physically or through detailed data if the site isn't accessible yet. We calculate the connected loads, demand factors, starting currents for large motors, and the fault level the system needs to withstand. This is the foundation the rest of the design is built on.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Concept Design & Technology Selection<\/h3>

We develop the system concept: generation capacity, voltage levels, technology mix (diesel only, hybrid, BESS-integrated), and distribution architecture. For remote mining sites in WA, this includes a fuel cost and availability analysis and a realistic assessment of whether hybrid solar-diesel makes economic sense for the site, not just a default recommendation.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

We design power systems across LV (415V) and HV ranges including 6.6kV, 11kV, 22kV, and 33kV. For most remote mining sites in the Pilbara and Goldfields, we work at 11kV distribution with 415V LV reticulation, stepping up from generators via HV transformers. We also design underground HV systems for operating mines where surface-to-underground power distribution is required.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Can Silverstone design a hybrid solar-diesel power system for an off-grid mine site? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

Yes. We design hybrid solar-diesel systems for off-grid mining operations across Western Australia. Our hybrid design scope includes solar PV yield modelling, BESS sizing, diesel generator sizing for firm capacity, dispatch logic design, and protection coordination between all generation sources. We’ll also give you an honest assessment of whether the fuel savings justify the capital cost on your specific site; not every site makes a viable hybrid candidate.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Do you produce as-built documentation and commissioning test packs? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

Yes. Every power system design Silverstone delivers includes a commissioning test pack: test procedures, relay test records, insulation resistance and high-pot test results, and inspection checklists. After commissioning, we produce as-built drawings that reflect what was actually installed. Because we commission what we design, the as-built records are accurate. They’re produced by the same engineers who designed and built the system.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Our power system designs comply with AS\/NZS 3000 (Wiring Rules), AS 2067 (Substations and high voltage installations), AS 4086 (Secondary batteries for use with stand-alone power systems), and relevant Western Power and Horizon Power network connection requirements for grid-connected or embedded generation applications. For mining-specific applications, we also design to the requirements of the Mines Safety and Inspection Regulations 1995 (WA).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/section>\n\t\t
