This record is the Cronimet Chrome/Thaba open-pit chromium mine near Thabazimbi, Limpopo, and duplicates the legacy page titled 'Thabazimbi Chrome Mine Microgrid.' The plant commissioned in November 2012 as a 1 MWp PV system integrated with two 800 kVA diesel generators through SMA's Fuel Save Controller. A 500 kVA utility connection was added in 2014, changing the operating boundary from fully off-grid to a solar-diesel-grid hybrid. There is no battery storage in the documented installation.

Research status
SMA still presents the project as a current reference and states operation since November 2012, but the latest project-specific performance account found is from 2015. No 2022–2026 mine-owner report confirms PV condition, mine production status, realized generation, or retirement. The plant is therefore operational as last publicly reported/currently marketed, not independently verified continuously operating in 2026; nearby modern mines and solar projects are unrelated and excluded.

Project delivery

Who was involved in Thabazimbi chromium mine?

8 publicly identified organizations. Where a recovered source named a participant without explaining its work, the role remains explicitly unspecified.

Organization

Cronimet Chrome Mining SA (Pty) Ltd.

Mine operator and power-system customer [2][4]

Organization

Cronimet Chrome Mining SA (Pty) Ltd. / Cronimet Mining S.A.

Mine operator and hybrid-power customer/operator named by SMA. [5][8]

Organization

Cronimet Energy SA

Project financier and renewable-energy project entity [4]

Organization

Cronimet Mining Power Solutions

Hybrid-power developer and energy-solutions provider [4]

Organization

Cronimet Mining Power Solutions / Cronimet Energy SA

Hybrid-project developer/energy company and financier under the original PPA structure. [8][11]

Organization

SMA Solar Technology

PV inverter and Fuel Save Controller supplier/integrator. [5][6]

Solea Renewables

Turnkey solar EPC contractor [4]

Organization

Solea Renewables / Solea AG

Turnkey PV planning and EPC contractor. [6][8]

System evidence

Energy mix, capacity, and specifications

Values can describe different project phases, generation sources, storage systems, or other components. Source citations are attached to each figure so discrepancies remain visible.

Solar PV
1 MW [2][4]
Reported solar generation
Up to 1.8 GWh per year [2]
Reported diesel savings
Approximately 450,000 litres per year [4]
PV penetration capability
Up to 60% under SMA Fuel Save Controller operation [3]
Solar PV
1 MWp from approximately 4,200 modules. Module manufacturer/model is not disclosed in authoritative project material. [5][10]
PV inverter fleet
63 SMA Sunny Tripower 17000TL units, 1,071 kVA aggregate nominal inverter capacity. [6][5]
Diesel generation
Two 800 kVA generator sets (1.6 MVA aggregate); engine manufacturer/model and kW power factor are not published. [5][7]
Grid addition
A 500 kVA grid connection was added in 2014, so later operation was no longer strictly off-grid. [8]
Expected/early performance
Up to 1.8 GWh/year solar, approximately 450,000 litres/year diesel reduction from a historical 1.9 million-litre burn, and up to 60% PV penetration. These are early project expectations/case-study results, not 2026 measurements. [5][8][9]
Energy mix
Solar during daylight, diesel for firm power, plus limited grid imports after 2014. No current annual percentage split is available. [5][8]

Controls and hardware

Equipment and controller details

Manufacturer and model are shown only when a source names them. Generic descriptions are not converted into guessed product assignments.

01

Hybrid controller

SMA — Fuel Save Controller

Controls PV feed-in against mine load and diesel operating conditions to maintain stability. [2]

02

PV inverters

SMA — Sunny Tripower

Model variant and unit count were not stated on the reviewed reference page. [2]

03

PV inverters

SMA Solar Technology — Sunny Tripower 17000TL

63 three-phase units, 1,071 kVA aggregate. [6]

04

Hybrid controller

SMA Solar Technology — Fuel Save Controller

One controller regulates PV feed-in against load, diesel minimum loading and operating reserve. [5][6]

05

Diesel generators

Model not publicly disclosed

Two 800 kVA units; maker/model undisclosed. [5]

06

Energy storage

Model not publicly disclosed

None documented; the controller curtails/dispatches PV against rotating generation rather than relying on a battery. [6][5]

Technical record

Architecture, performance, and project updates

Concise technical facts, milestones, operating results, and later developments. Dated notes distinguish historical design claims from current evidence.

  • Generation

    PV, Diesel [1]

  • Control architecture

    The Fuel Save Controller monitors mine load and genset conditions and commands the PV inverters to maximize solar while retaining adequate diesel reserve and stable isolated-grid operation. [5][7]

  • Commercial model

    Project reporting describes a PPA/financed arrangement that avoided mine-owner upfront PV investment; contract term and current ownership were not found. [11]

  • Duplicate/identity warning

    The two Thabazimbi/Thaba legacy slugs describe the same Cronimet installation. Northam's 80 MW Zondereinde solar project and the newer Thaba JV are separate projects and are not additions to this microgrid. [5]

  • Current-data gap

    SMA's live reference supports continuing recognition of the installation but does not give recent availability, solar yield, diesel use, grid share, or decommissioning status. [5]
