Solar Solutions for Mining Industry - Mining

SolarReserve’s proven technology delivers a cost-effective, reliable and most importantly, a baseload supply of electricity that is critical to mining operations. This innovative approach to clean power generation provides the mining sector with a reliable, 24 x 7 power supply, to help them displace the high price of conventional electricity generation and hedge against fuel price increases in remote locations.


Mining operations, particularly those operating off-grid, have a unique set of requirements for power supply. SolarReserve has developed a suite of solutions for the mining industry with those requirements in mind, delivering significant savings and predictable energy costs to mining operations around the globe that are cost competitive with conventional energy sources.

Reliable 24/7 Baseload Supply

Mines operate 24 hours a day, practically every day of the year. Mining operators expect full reliability and availability from their power systems, with very low tolerance for outages or shortfalls. Most mines operate at a 70% to 90% annual load factor relative to their peak load, but peak loads can occur at any time of day in any season. Due to their inherent variability, most renewable technologies, like photovoltaic panels (PV) and wind, can only address a small fraction of the mine’s energy needs, and are not reliable enough for off-grid power. However, by using fully integrated molten salt storage, SolarReserve offers Concentrating Solar Power (CSP) solutions that are as reliable and available as conventional technologies, but fueled by the sun.

Energy Security

An off-grid mine has no backup from a utility transmission system; so no capabilities to obtain reserve power, system inertia, voltage support, or other grid services. The mine’s power source must supply all of these attributes itself. The nearest transmission line or natural gas pipeline may be hundreds of kilometers away. Even when a transmission grid exists nearby, it may be too fragile and unreliable. SolarReserve’s power plants, with the right combination of solar energy storage and steam generation, can operate in isolation and provide all of these services seamlessly through dedicated supply to the mine, and with minimum reliance on fuels like diesel or natural gas.

Fuel Abatement

Supplying diesel to a remote mine can be a very expensive proposition since it is typically trucked to a mine over long distances. Natural gas supply can also be very expensive, given the cost of building pipelines to remote areas. Energy supply is typically around 25% of a mine’s operating costs and fossil fuel based, which increases the risks from carbon tax regulations, environmental permitting, and fuel price volatility. Solar energy can significantly reduce cost and reduce risk. Integrating storage for a fully baseload solar supply will eliminate fuel risk while still reducing costs, improving competitiveness, and enhancing sustainability.

Lower Energy Costs while Focusing on Minerals

Mining companies are focused on the resources. The changing landscape around carbon emissions and renewable energy creates challenges that are best managed by working with an experienced partner. That’s why SolarReserve offers complete turnkey solutions for energy supply, so that our customers can focus on their core business activities.


SolarReserve offers mining companies the most reliable baseload solar generation on the planet, enabled by our industry leading CSP and molten salt storage technology.

Solar Solutions for Predictable, Cost Effective Power

SolarReserve’s products minimize fuel use and thereby reduce exposure to volatile fuel prices. The degree of fuel abatement varies based on the size and scope of the solution: a smaller solar project can offset a portion of fuel consumption, while a larger project can fully replace conventional power infrastructure, eliminating the need for the mine to build its own fuel supply, power plant or transmission line.

The Complete Power Supply Package, Customized

SolarReserve offers an end-to-end energy supply solution, which includes suitability assessment, technology configuration, permitting support, finance and EPC management, and ongoing power plant operations or operational support. The energy supply agreement can be structured such that all technologies are integrated behind the fence at SolarReserve’s facility, or SolarReserve can transfer control of the assets to the mine operator. In either case, the mine will enjoy a guaranteed fixed price of energy for the life of the project.
