Project: Cheetah Plains
|PV System Size:||300 kWp|
|Battery System Size:||1MWh|
|Electricity Generation:||460 MWh|
|Estimated Co2 savings:||432t/annum|
|Estimated lifetime benefits:||R38 Million – 20 years|
Cheetah Plains was initially constrained by a single-phase power supply that put out a maximum of 64kVA. This inhibited the upgrading of their facilities.
Transformers were negatively impacted, resulting in considerable damage to the facilities equipment and the transformers.
To allow for expansion, a more powerful three-phase power system was implemented with a 150kVA diesel generator backup. A solar PV facility was created with solar tracking, due to limited space for solar panels. Paired with a high-quality Lithium-Ion battery Storage system, Cheetah plains is able to stay up and running 24/7 with power harnessed solely from the sun.
The solution developed by a combination of the South African solar company Blockpower and the German microgrid integrator, DHYBRID, consists of:
- A 150 kVA diesel generator
- A 300 kWp solar panel array
- And a 250 kW/1027 kWh Battery Energy Storage System
Cheetah Plains has saved approximately 470MWh of energy to date, with potential savings of 550MWh per year.
