Slide 13: Solar farm
Solar farm Key facts + Solar farm will take up approximately 140ha of land. + It will use approximately 75,000 solar panels. + It will produce around 40MWp of power when there is enough sunlight. + Some power some will go directly to storage when the batteries are not fully charged. + The solar pane
Slide 14: Wind farm
Wind farm Key facts We are proposing to have up to 10 wind turbines Each turbine will produce around 6MW, giving a total of 60MW. . s The height of the wind turbines will depend on the manufacturer. af The tallest model available for the project is 155m tall when measured at the hub, and 240m tall w
Slide 15: Battery storage
Battery storage Key facts + Batteries add to the reliability of supply by charging when there is excess renewable energy and discharging when there is not enough wind and sun. + Batteries also provide grid stability, safety and control functions. + The batteries will store 30MWh of renewable energy
Slide 16: Diesel generators
Diesel generators Key facts The generators will run at the beginning of the project to supply power while the renewable energy sources are brought online. The generators will then only be switched on when there is not enough wind, sun or stored renewable energy, or when restarting the microgrid afte

Slide 18: What will it look like?
will it look like? ct from the proposed project ‘ct will be mainly visible from the mine itself. lookout you will see the wind turbines off in the round 22 km from the lookout. + The diesel generators and battery storage will probably be too low in the viewing field as they are only around 3 metres
