mines unlock value from big power data “Having recently opened

our South African office we see a huge opportunity to help the domestic mining and industrial operations sectors,” Yannaghas explains. “There is not a lot we can do about the level of load shedding taking place in South Africa, but we are able to help the industrial sector maximise its efficiency and manage any power transition (to solar for example).” VoltVision is cur rently helping Anglo American at its Mogalakwena platinum mine, located in Mokopane, Limpopo Province, to manage the power networks on its pro totype hydrogen electrolyser, which is set to generate the hydrogen needed to power its new hybrid mining trucks. Further to this, the technology specialist recently completed the first phase of a programme to digi tise the power networks at Endeavour Mining’s six West African gold mines (Ity mine in Cote d’Ivoire; and Hounde, Mana, Karma and Boungou mines in Burkina Faso as well as Sabodala-Massawa, the largest producing gold mine in Senegal) and it is busy with Phase 2 of the project. Phase 1 of the project was designed to help maximise the efficiency of Endeavour’s electrical power systems, enabling it to improve power qual ity, increase uptime and reduce CO 2 emissions, while lowering energy consumption and operating costs. Endeavour has identified significant power efficiency gains with both CAPEX and OPEX cost savings as the project has been rolled out. VoltVision has progressed to Phase 2 of the roll-out, which is focusing on condition monitoring, failure prevention and further power reduction analysis. “This is the only retrofit digitisation solution commercially available for high and medium volt age power networks in the mining industry,” says Yannaghas. It can be installed, operated and man aged remotely, and requires no site visits from VoltVision representatives and no shutdowns. “This,” Yannaghas emphasises “is not only a highly innova tive feature but one that is ideal for mines situated in remote and extreme environments.”. He adds that because the technology is plug and-play, Phase 1 was installed successfully by Endeavour’s own engineers, without any site visits from VoltVision or any disruptions to production, proving its suitability for remote and hostile envi ronments. 

VV Asset has been proven to reduce the energy required for the crushing process by 20%.

VoltVision Power helps companies reduce their static power and CO 2 emissions by up to 10%. VV Net Zero allows you to measure these CO 2 reductions accurately.

VoltVision technology  VoltVision’s IoT, data extraction Gateway, the V-CUBE, is a key enabler help ing mining houses, large and small, to access power data for use on and off-site through their own, or VoltVision’s ViViD, cloud platform.  VoltVision’s digitisation programme works by retrofitting its V-CUBE IoT data extraction gateways to existing electrical protection equipment (regardless of age or manufacturer).  The V-CUBE extracts detailed system and/or asset performance data 24/7, which is then stored in the cloud, saving millions in the high cost of in situ historian databases.  VoltVision converts HV and MV data into actionable information, which is made available on its ViViD platform through dashboards, reports and alerts for use by operations and management teams, and which is available to them anywhere in the world.
