Assess Power Needs

Identify Equipment Loads

Start by making a list of all equipment that will use power from your generator. Write down each item's name, type, and power rating. Some common machines are compressors, pumps, and HVAC systems. Air tools need a certain amount of air called CFM at a set pressure. Most air tools use about 4.2 CFM, but sometimes they need up to 22 CFM. Big machines like pneumatic grinders use even more air. Check the duty cycle to see how often each tool runs at full power.

Tip: Make a table to keep track of your equipment loads. This helps you know which machines use the most power and when they run.

Calculate Total Power Requirements

After you list your equipment, add up all the power needs. Change the load size from kW to kVA. Use this formula:

kW = kVA × Power Factor (PF)

You need to know the kVA rating and power factor for each machine. This step helps you figure out the real power needed for your generator size. You can use online tools to help with these calculations.

Remember to include peak loads and loads that change. Motors use more power when they start up. For example, a 7.5 HP motor may need a generator sized to 22.5 kVA for the inrush current. Motors can pull six times their normal current when starting. Size your generator for 300% of the motor rating to stop voltage drops.

Note: Environmental factors can change your power needs. High temperatures make generators lose power. For every 18°F above 104°F, you lose about 10% power. At higher altitudes, you lose 3-4% power for every 1,000 feet. Humidity can also lower energy output.

Generator sizing software can help you be more accurate. These tools let you model loads, check load order, and use harmonic current signatures. Software like Power Design Pro lets you set custom voltage and frequency limits for each load. This gives you a better estimate of your power needs.

• Generator sizing software helps you model loads exactly.

• It uses many factors that affect generator sizing.

• The software gives you detailed analysis tools for smart choices.

Plan for Expansion

Think about future growth when you check your needs. If you want to add more machines or make your facility bigger, include extra capacity in your plan. The industrial sector uses a top-down method to guess total load by region and segment. You can estimate electricity use by big process and use energy-saving steps. Utilities now use advanced forecasting to manage energy resources and changing loads.

Tip: Always add a safety margin to your total power needs. This makes sure your generator can handle surprise jumps in demand.

Planning for expansion helps you avoid needing a new generator too soon. It also keeps your system reliable and efficient as your business grows.

Industrial Generator Types

Standby, Prime, Continuous

When you pick an industrial generator, you should know the main types. Each type works best for different jobs. There are three main types: standby, prime, and continuous. The table below shows how they are different:

A standby generator turns on when the main power stops. You use it for backup in places where losing power can cause problems. Prime and continuous generators run for longer times. You use them when you need steady power, like in remote places or big factories.

Match Type to Application

You need to pick the right industrial generator for your job. Here are some examples:

1. Hospitals use a standby generator for safety and patient care. It keeps important systems working during outages.

2. Data centers need a standby generator to keep servers and cooling running. Even short power loss can cause data trouble.

3. Factories and remote sites use a prime or continuous industrial generator. These places need power for long hours or all the time.

Tip: Always check your job before you pick an industrial generator. Think about how long you need power and how often you lose power.

Other things to think about are:

• Fuel type: Some places use natural gas, others use biogas or diesel.

• Budget: Pick an industrial generator that fits your money and works well.

Generator Sizing Steps

Step-by-Step Sizing Process

You should use a simple process for generator sizing. This helps you avoid mistakes and keeps your generator working well. Here is an easy guide you can follow:

1. Look at your utility bill. Find the highest power used each month.

2. Check which month had the biggest peak. Add 25 percent to this number for extra backup. This helps your generator handle sudden jumps in power.

3. Find the largest motor in your building. Multiply its starting current by the voltage. This gives you the watts needed to start it.

4. For other equipment, multiply the current by the voltage. This shows how many watts each item needs.

5. Add up all the watts from every load. Divide the total by 1,000 to get kilowatts.

6. Add 25 percent more to your total for extra backup. This helps your generator handle surprise spikes.

7. If you want a quick guess, use 50 kW for stores plus 10 watts for each square foot. For other buildings, use 50 kW plus 5 watts for each square foot.

8. Write down the starting and running wattage for every item. This helps you see which loads need more power.

9. Look at generator performance charts. Pick a generator that gives enough power for your needs.

Tip: Always leave a safety margin. Do not use your generator at full power for a long time. Try to use only 70-80% of its rated output. This keeps your generator working longer.

If you plan to grow, add 20-30% more power to your needs. This lets you add new machines without buying a new generator. Think about your building layout. Make sure the generator room has good airflow and enough space. Follow NFPA 110 and NFPA 37 rules for space around the generator. You should also think about space for fuel tanks and covers.

Common Mistakes

People often make mistakes when sizing a generator. These mistakes can cause big problems for your building. Here are some common errors and what they do:

• If you guess too low, your generator may be too small. This can make it overheat and not give enough power.

• If you pick a generator that is too big, you waste energy and pay more for repairs. You also spend more on fuel.

• If you forget about motor startup power, you may get voltage drops. This can hurt sensitive electronics.

• If you do not plan for growth, you may need a new generator soon. Always add extra power for future needs.

• If you ignore the building layout, you may have poor airflow and safety problems. The generator room needs enough space for cooling and access.

• If you use programs that do not support load diversity, you may size the generator wrong. This can hurt your emergency generator's performance.

• If you change plans during building, you may need a different generator size. Always check your plans before you choose.

Note: A generator that is too small may fail during a power outage. One that is too big can waste fuel and money. Always check your numbers and look at your building's needs before you decide.

If you follow these steps and avoid mistakes, you can pick the right generator size. This makes sure your emergency generator gives you power when you need it.
