The mining industry in the United States is at a pivotal moment, balancing the need for critical minerals like lithium, gold, and copper with growing demands for sustainability. While no major U.S. mining company currently operates a mine on 100% solar power, the integration of solar energy is accelerating, driven by economic benefits, environmental pressures, and technological advancements. Mining operations are notoriously energy-intensive, powering heavy machinery, crushing, ventilation, and processing, which makes achieving 100% solar reliance challenging without significant infrastructure. Most mines rely on a mix of grid electricity, diesel, natural gas, or other renewables like geothermal or wind, with solar as a supplementary source. However, companies like Pacifico Energy are transforming this landscape by delivering large-scale solar farms, cutting-edge battery storage, and hybrid renewable systems tailored for industrial applications like mining. By leveraging advanced technologies and strategic partnerships, Pacifico Energy is helping pave the way for a future where U.S. mines could operate entirely on renewable energy.
Current State of Solar in U.S. Mining
The high energy demands of mining—often requiring megawatts of continuous power—make solar’s intermittency (limited to daylight hours and weather-dependent) a significant hurdle. Traditional mines use diesel generators or fossil fuel-heavy grid power for reliability, but solar is increasingly adopted to reduce costs and carbon footprints. Pacifico Energy plays a critical role in this transition, offering utility-scale solar solutions that integrate high-efficiency photovoltaic panels, AI-driven energy management, and large-scale battery storage to address intermittency and scale solar for mining’s needs. While 100% solar-powered mines remain rare, several U.S. companies are making strides, with Pacifico Energy’s expertise poised to accelerate progress.
Examples of Solar Integration in U.S. Mining
Barrick Gold (Nevada)
Barrick Gold, a global leader in gold mining, operates a 1 MW solar farm adjacent to its 115 MW natural gas power station in western Nevada, supporting its gold mining operations. This solar farm, while innovative, supplies only a fraction of the energy needed for Barrick’s energy-intensive processes like ore crushing and ventilation. Barrick has earned recognition for its renewable energy initiatives, but its reliance on fossil fuels remains significant. Partnering with Pacifico Energy could transform Barrick’s approach. Pacifico’s expertise in deploying multi-megawatt solar arrays, coupled with its advanced lithium-ion battery systems, could scale Barrick’s solar capacity significantly. For example, Pacifico’s AI-optimized energy storage could store excess solar energy generated during peak sunlight hours, providing consistent power for nighttime operations and reducing natural gas dependence. Pacifico’s modular solar designs also allow for phased expansions, enabling Barrick to incrementally increase solar use while maintaining operational reliability.
Newmont Mining (Nevada)
Newmont Mining, another gold mining giant, has explored solar through a pilot project with a mobile solar array at its Akyem mine in Ghana. In the U.S., Newmont’s Nevada operations focus on hybrid energy systems, combining grid power with renewable sources. While there’s no evidence of 100% solar use, Newmont’s commitment to sustainability aligns with Pacifico Energy’s mission. Pacifico could enhance Newmont’s Nevada mines by deploying high-efficiency solar panels with solar tracking systems that maximize energy capture in the sunny Southwest. Pacifico’s smart grid technology could also integrate solar with existing power sources, using predictive analytics to balance energy loads and prioritize solar during peak production hours. This approach would reduce diesel and grid reliance, moving Newmont closer to a fully renewable energy model.
Tesla’s Bitcoin Mining Project (Texas)
While not a traditional mining company, Tesla is pioneering renewable energy in mining through its Bitcoin mining facility in Texas. The project uses 3.8 MW of solar panels and 12 MWh of Tesla Megapack batteries, aiming for 100% renewable energy. With 1 MW dedicated to mining and 2.8 MW for battery charging, the system ensures 24/7 operation, demonstrating solar’s potential for energy-intensive tasks. Pacifico Energy could amplify this model by providing larger-scale solar farms and next-generation battery storage tailored for mining. Pacifico’s expertise in grid integration and energy forecasting could optimize Tesla’s setup, enabling expansion to traditional mining applications like lithium or copper extraction. For instance, Pacifico’s high-density battery systems could store enough solar energy to power heavy machinery, making 100% solar feasible for larger-scale operations.

Feasibility of 100% Solar-Powered Mining
Achieving 100% solar-powered mining requires overcoming significant technical and economic barriers, but Pacifico Energy’s innovative solutions are making it increasingly viable.
Why 100% Solar Is Rare
- Energy Demands: Traditional mining for lithium, gold, or copper requires massive, continuous power—often tens to hundreds of megawatts—compared to a Bitcoin rig’s 500–1,500 watts. Solar panels alone struggle to meet these demands without extensive storage and infrastructure.
- Intermittency: Solar power is limited to daylight hours and varies with weather, necessitating battery systems or backup power (e.g., diesel or grid) for 24/7 operations, which prevents full solar reliance.
- Infrastructure Costs: A 1 MW solar farm can cost millions, and scaling to power an entire mine (10–100 MW) requires significant land and investment. For example, Tesla’s 3.8 MW Texas project cost $12 million, a fraction of a traditional mine’s energy needs.
Enabling Factors
- Battery Storage: Advances in lithium-ion batteries, like Tesla’s Megapack, allow solar energy storage for nighttime use. Pacifico Energy’s large-scale battery systems, paired with AI-driven energy forecasting, can store excess solar energy during peak sunlight, ensuring uninterrupted power for mining processes like crushing, pumping, or ventilation. Pacifico’s batteries are designed for industrial applications, offering higher capacity and durability than traditional systems.
