Natural Gas Generator Sizing

Sizing Basics

You need a generator that fits your needs now and later. Sizing means you find out how much power you use when it is busiest. There are a few ways to do this. Some people check the highest power their building uses. Others look at old bills or records to guess. If you have many machines, you must count their starting power too. Some people use the size of their building to help them decide.

Here are some common ways to size a generator:

Tip: Always check your highest power use, not just the average. This helps you make sure you have enough power when you need it most.

Capacity Range (900-2000kW)

LIYU's gas-fired generator sets give you many choices. You can pick models from 900 kW to 2000 kW. These generators are good for big jobs. You see them in large buildings, data centers, factories, hospitals, and big construction sites.

LIYU's generators are special because they work very well. You get electrical efficiency from 38.8% to 40.2%. This is as good as the best in the business. Total efficiency is even higher, from 83.9% to 87.8%. This means you get more power from each bit of fuel.

• LIYU's generators work for many places.

• You get strong and steady power.

• The range fits most big business and city needs.

Maintenance is important too. If you plan ahead, you save money and stop problems. Quick repairs can take just a day or two. Big repairs take longer, but you can plan them. Good care costs between 0.7 and 1.3 cents per kilowatt-hour. If you skip care, you may have engine trouble and pay more.

Note: Picking the right size natural gas generator saves money, keeps your business running, and helps you grow in the future.

What Size Generator Do I Need

Power Needs Assessment

You may ask, "What size generator do I need for my business?" The answer starts with checking your power needs. You want your natural gas generator to handle everything you use, even at the busiest times.

Here's an easy way to find your total wattage:

1. List all equipment and systems you want to power. This includes lights, HVAC, elevators, computers, and heavy machines.

2. Check the wattage for each item. Look for it on a label or in the manual.

3. Add up the running wattage for everything that runs together.

4. Identify equipment with motors or things that need extra power to start. These items have higher starting wattage.

5. Add the highest starting wattage to your total running wattage. This gives you your peak load.

Tip: Always use the biggest number you find. This helps you avoid losing power when things get busy.

You may see different peak loads in real life. Construction sites need more power as work grows. Microgrids mix renewable energy with generators, so their needs change often. Remote places, like mines, need steady power but sometimes need more for big machines. Hospitals and emergency systems must handle changing loads, starting with the most important things first. Big events, like concerts, use hybrid systems to manage peak loads and save fuel.

If you want things to be simple, LIYU has solutions that can grow with you. You can start with one generator and add more later. This way, you do not have to worry about outgrowing your system.

Running vs. Starting Watts

When you ask, "What size generator do I need?" you should know about running and starting watts. Some equipment, like motors or compressors, need extra power to start. This is called starting wattage. When they run, they use less power, called running wattage.

Here's a table to help you understand:

You should always count both numbers when you pick generator size. If you only count running wattage, your generator may not start all your equipment at once. If you only count starting wattage, you may pick a generator that is too big and costs more.

Safety Margin

You should not run your generator at full power all the time. It is smart to add a safety margin when you choose your generator. This gives you room for surprise power needs and helps your generator last longer.

Most experts say to add 20% to 25% extra capacity to your total watts. Here's a table to show the recommended safety margin:

So, after you finish your generator size, multiply your total wattage by 1.2 or 1.25. This gives you a safe number to use when you pick your generator.

Note: If you plan to grow your business or add more equipment, LIYU's generators make it easy to upgrade. You can connect more units or pick a bigger model when you need it.

When you follow these steps, you can answer, "What size generator do I need?" with confidence. You will know your power needs, understand your wattage, and have a safety margin for peace of mind. LIYU's flexible solutions help you size your generator for now and later.

Key Factors for Sizing

Load Profile

You need to know your load profile to size a generator. This means you look at what you want to power and how much energy each thing uses. Think about both starting and running loads. Some machines use more power to start than to run. You should plan for the most electricity you might use at one time.

Here's what to put in your load profile:

• Total power needed for your site

• Starting loads for motors or big equipment

• Running loads for all devices

• Extra capacity for future needs

• Highest electricity use during busy times

• Size of your building in square feet

• Old energy bills for past data

If you want an easy way, list all items, find their starting and running wattage, and add them up. This helps you pick the right generator size for your needs.

Fuel Options

You can pick from different fuels. LIYU generators use natural gas, biogas, and hydrogen. Each fuel has its own good points. Hydrogen is popular because it does not make emissions. Many companies like it for clean energy. Biogas is good for farms and places that recycle waste. It helps with renewable energy and waste problems.

LIYU's technology lets you use many gases. You get cleaner air and less pollution. This makes your generator more flexible and helps you meet your power needs in a greener way.

Installation Site

Where you put your generator is important. Hot or cold weather can change how much power your generator gives. If your site is high up, like on a mountain, you may lose some power. For every 1,000 feet above sea level, you lose 3-4% of your generator's power. If it gets hotter than 104°F, you lose about 10% for every 18°F above that.

Always check the temperature and altitude at your site before you pick your generator size. This helps you meet your power needs without surprises.

Compliance

You must follow rules when you install a big natural gas generator. Local building codes tell you where to put your generator and how to keep it safe. You need good airflow to stop health risks. Safety steps help prevent fires and carbon monoxide problems.

Some places have extra rules, like the CSA C282 standard. This covers how you set up, test, and take care of your generator. Always check your local laws before you start.

Tip: If you want to use combined heat and power systems, LIYU generators can help you save energy and lower costs. These systems use the heat from your generator to warm your building or make hot water. This can change your power needs and affect your sizing plan.

Whole House Generator vs. Large-Scale Solutions

Residential vs. Industrial Needs

When you want backup power at home, you might think of a whole house generator. These generators keep your lights, fridge, and air conditioning working if the power goes out. Most whole house generators give between 22 and 48kW of power. They have strong engines that use liquid to stay cool. These engines can run for a long time without stopping. Smart controls help you choose which things get power first. You can pick natural gas, propane, or diesel as fuel.

A home standby generator is good for families who want to feel safe during storms or blackouts. It lets you keep living almost like normal when the power grid fails. Home generators are much smaller than the ones used for big businesses or factories.

Now, let's talk about large-scale solutions. If you run a hospital, data center, or factory, you need a natural gas generator with much more power. These big systems start at 900kW and can go up to 2000kW or even more. They keep whole buildings, machines, and city services working. You need this much power in places where losing electricity is not okay.

Tip: A whole house generator keeps your home safe and comfortable. Large-scale generators protect businesses, hospitals, and cities from big problems.

Application Scenarios

You can find large-scale generators in many places. Here are some examples:

LIYU's generator technology works in all these places. You get quick power when you need it most. You can use LIYU generators for disaster help, building sites, big events, or temporary buildings. They work well in bad weather and hard-to-reach places. You can control them easily with smart systems. You can also choose the right size and fuel for what you need.

Choose the Right Generator Size

Sizing Checklist

You want to feel confident when you choose the right generator size. A checklist can help you stay organized and make sure you do not miss anything important. Here is a simple step-by-step guide:

1. List all the devices and systems you need to power at the same time.

2. Check the running watts for each device. You can find this on the label or in the manual.

3. Write down the starting watts for each device. Some equipment, like air conditioners or pumps, need more power to start.

4. Find the device with the highest starting watts. Add this number to your total running watts. This gives you the minimum size your generator should be.

5. Think about special needs, like heating, cooling, medical equipment, or water pumps.

6. Add a safety margin of 20-25% to your total. This helps your generator handle extra loads and last longer.
