Section 12B Solar Tax Deduction for Mining & Quarrying

Mining operations are the largest industrial electricity consumers in South Africa. With processing plants, ventilation systems, conveyors, and pumping stations running around the clock, solar provides significant cost relief. Section 12B's 125% first-year deduction makes large-scale solar installations financially compelling even at lower Eskom tariff rates.

Mining & Quarrying Energy Profile

Mines consume electricity continuously, but daytime loads from processing, crushing, and conveyor systems align with solar output. A 500 kW system offsets a meaningful portion of the daytime base load while grid power covers underground and overnight operations.

How Section 12B Benefits Mining & Quarrying

A mining operation investing R7 million in solar claims a R8.75 million Section 12B deduction. At 27% tax, this delivers R2.36 million in first-year tax savings, bringing the effective cost down to R4.64 million.

Mining sites offer extensive open land for ground-mount solar arrays. Processing plant rooftops and tailings dam embankments also provide viable installation areas. Dust management for panels is a key maintenance consideration in mining environments.

Frequently Asked Questions

Yes. While underground operations run 24/7, surface processing plants, offices, and workshops consume substantial daytime electricity that solar can offset. Battery storage extends the benefit.

Dust can reduce output by 5-15% if panels are not cleaned regularly. Automated panel cleaning systems or periodic manual washing maintains optimal performance on mining sites.

Even at lower key-customer rates of R1.50-2.50/kWh, the Section 12B deduction makes solar viable. The tax saving alone covers a significant portion of the investment in year one.
