Caterpillar to supply solar power to B2Gold mine

The full system, including Cat photovoltaic (PV) solar modules and the Cat microgrid master controller (MMC), will be used to reduce reliance on a heavy fuel oil (HFO) power plant currently used to power the mining facility. Barloworld is supplying engineering, procurement and construction services for the project. Installation of the system is underway, with the completion of the project expected in early 2018.

“At B2Gold, we embrace environmental stewardship and social responsibility as key corporate priorities in doing business,” said Mark Dawe, Managing Director and Country Manager for B2Gold Namibia. “As one of the largest solar installations in Namibia, the facility at the Otjikoto Mine will help us to leverage a plentiful, renewable resource while improving the quality of life for nearby communities.”

Advanced solar technology from Caterpillar

Caterpillar’s solar PV system is powered by advanced thin-film solar modules that are setting the industry benchmark with improved performance over conventional silicon solar panels. Fully scalable and pre-engineered for quick and easy installation, the system offers reliable and predictable energy in all climates and applications with modules that are independently tested to pass accelerated life and stress tests beyond industry standards.

Caterpillar’s solar PV offering is a key component of the Cat Microgrid technology suite, an innovative lineup of power systems that adds environmentally friendly solar panels, state-of-the-art energy storage, and advanced monitoring and control systems to Caterpillar’s traditional line of reliable power generation equipment, including HFO, natural gas and diesel generator sets, switchgear and automatic transfer switches. The Cat Microgrid technology suite is designed to reduce fuel expenses, lower utility bills, decrease emissions, and reduce the total cost of ownership while increasing energy efficiency in even the most challenging environments.

A key differentiator in Caterpillar’s offering is the Cat MMC, which keeps loads continuously energised with high-quality power at the lowest cost. It manages the flow of power from every source in the system, including the main grid when connected. The Cat MMC determines optimum recharge times for the energy storage systems while managing power during times when solar energy is not available.

The MMC also uses Cat Connect technology for real-time collection and communication of on-site performance data that can be monitored and analysed remotely.

“The economic viability of remote mining operations depends on the cost-efficient generation of power,” said Tom Frake, vice president of the Global Power Solutions Division for Caterpillar. “Caterpillar’s solar technologies provide a scalable, sustainable power solution that significantly reduces fuel consumption while delivering the reliable power needed to support mining sites.”

B2Gold’s Otjikoto Mine is located in the region of Otjozondjupa approximately 190 miles (300 km) north of the capital city of Windhoek. The mine reported a record year in 2016, producing 166 285 ounces of gold. Caterpillar supplied the original 25 MW of power capacity to the Otjikoto Mine when it opened in 2014 through four Cat 12CM32 HFO medium-speed engines and three Cat 3516B high-speed generator sets.

“For many years, B2Gold has relied on dependable, high-performing Cat equipment for both power solutions and mining operations at the company’s mining sites around the world, which is why executives again selected Caterpillar and Cat dealer Barloworld to help reduce operational costs while improving the sustainability profile at the Otjikoto Mine,” said Jean Savage, vice president of Surface Mining and Technology for Caterpillar.

Caterpillar is a leader in the power generation marketplace with power systems engineered to deliver unmatched durability, reliability and value. The company offers worldwide product support, with parts and service available globally through the Cat authorised service and dealer network. In addition, dealer service technicians are trained to service every aspect of Cat equipment.
