We have added all the key factors and details here.

Wenk #4: Calculate Backup Power Requirements

How much power does your system need? It is essential to understand and know.

Suppose you are running the following equipment. Calculate all the power requirements for the following tools.

Let’s calculate the running load.

Totale lopende lading = 96 + 60 + 48 + 45 + 80 + 20 + 35 + 8

Total = 392 kW

You should never buy a generator with a rated running load. In plaas daarvan, keep a safety factor of 20-25% for future expansions and power handling.

Suppose you are looking for 25% of the additional capacity. Then the power requirements of the generator capacity should be:

Generator Capacity = 392 × 1.25 = 490 kW

You should buy a generator with a 500kW capacity to meet all the power needs and requirements.

Wenk #5: Plan for Future Manufacturing Expansion

Are you going to increase the system in the future? It is typical that most people expand the system in the future. Hiervoor, you should know which tools you are going to add.

Future Load

Current Backup Load = 392 kW

Future Expansion = 255 kW

Future Total = 647 kW

Adding a 25% reserve:

647 × 1.25 = 809 kW

Add a generator of 810-850 kW capacity or more to meet the future needs.

Wenk #6: Determine Acceptable Downtime

You should understand the acceptable downtime of each tool. There are different tools that won’t even bear a single second of downtime.

You should understand the range of acceptable downtime.

Wenk #7: Choose Right Backup Option
