A 100%-uptime microgrid for a copper mine's communications network.
The network 2,500 workers depend on ran on diesel.
This Central Arizona copper mine runs a closed communications network that more than 2,500 employees rely on to coordinate operations and stay safe. The tower and support buildings sit on a rugged peak inside the mine and ran on diesel alone; extending utility power up the mountain was ruled out by cost and disruption to mining operations.
A dedicated microgrid engineered for zero downtime.
In 2024 the mining group contracted NewGrid to design and build a dedicated off-grid microgrid for the site: 80 kW of solar, 615 kWh of outdoor-rated lithium storage, 120 kW of Schneider inverters, and a 60 kW diesel generator in reserve.
- 80 kW solar
- 615 kWh Sol-Ark L3 outdoor lithium battery
- 120 kW Schneider inverters
- 60 kW diesel generator
- 277/480V three phase
Running without interruption since day one.
Commissioned in December 2024, the microgrid has run at 100% uptime since. NewGrid is now engaged with additional mining clients as microgrid adoption spreads through heavy industry.
