Suntrace and Baywa r.e. complete largest off-grid solar-battery hybrid system for mining industry

Suntrace GmbH and BayWa re, together with B2Gold Corp. (CA) completed commissioning of the world’s largest off-grid solar battery hybrid system for mining at the Fekola gold mine in Mali, West Africa. The solar battery hybrid system was successfully integrated into the existing power plant operation and put into operation. The solar system should be 100% complete by the end of June.

Such hybrid projects, which combine solar energy with conventional energy generation and battery storage, are an effective way of providing a reliable power supply day and night in off-grid areas. B2Gold was ideally tailored to their needs and approved the hybrid project for implementation in July 2019 after the preliminary studies by Suntrace and BayWa re were completed.

The Fekola gold mine operates around the clock. During the day, three of six heavy oil generators can be switched off with the new 30 MW solar system. The energy production of the remaining three generators could also be significantly reduced. The 15.4 MWh battery storage compensates for fluctuations in energy generation and ensures reliable operation, with up to 75% of the goldmine’s electricity needs being covered by renewable energies during the day.

Dennis Stansbury, Senior Vice President at B2Gold, commented, “Suntrace and BayWa re have played an important role in our work towards more sustainable manufacturing at Fekola. Implementing a solar-battery hybrid system was an obvious choice to achieve this, it was not This is a landmark project that we expect to pave the way for more sustainable mining power generation in West Africa. “

The integration of the solar power plant into the battery system ensures a safe and reliable power supply, saving 13.1 million liters of heavy fuel oil (HFO) annually. The close cooperation of all three parties as one team was crucial to the implementation of this complex project and helped to realize the enormous potential of solar battery hybrid systems.

Martin Schlecht, COO at Suntrace, commented: “We are very proud that B2Gold has commissioned Suntrace together with BayWa as a contractor for engineering and procurement to support the development and implementation of this innovative project. Thanks to the excellent teamwork with B2Gold and BayWa Wir were able to manage the completion despite the global challenges the COVID-19 pandemic posed for all of us. We are proud to work together to deliver a working project that is well integrated with mining and reduces CO2 emissions from the Electricity generation for the Fekola mine reduced by around 20%. “

The PV battery system will help reduce CO2 emissions by 39,000 tons per year.

Thorsten Althaus, Project Manager at BayWa re, added: “The safe and reliable integration of such a large amount of solar in a small, isolated network was a major technical challenge and required the use of battery storage and a tailor-made control system Project and we made sure that our vision was implemented accordingly by the suppliers. It is extremely rewarding to see how well this solution works in reality and shows that the technology works and is just waiting to be applied to further projects . “

Promote the introduction of solar energy in rural India

Washington DC (SPX) April 9, 2021

More than 73 million households in remote areas of the world get their electricity not from a conventional power grid, but from sources such as solar lanterns, solar home systems (SHS), which can supply multiple devices, and local solar-based microgrids. Such off-grid devices and systems provide life-changing services to people who are not connected to centralized power grids and help spread the use of renewable energies. As a result, international aid agencies and non-governmental organizations (NGOs) … read more
