Hey there! As a supplier of Prime Power Diesel Generators, I often get asked about converting these generators to run on natural gas. It's a question that comes up a lot, especially with the rising costs of diesel and the increasing availability of natural gas. So, let's dive into the nitty - gritty of how much it costs to make this conversion.

Why Convert to Natural Gas?

Before we get into the costs, let's quickly talk about why someone might want to convert a prime power diesel generator to natural gas. Natural gas is generally cheaper than diesel, which can lead to significant cost savings in the long run. It's also a cleaner - burning fuel, which means fewer emissions and a smaller environmental footprint. Plus, natural gas is more readily available in many areas, reducing the risk of fuel shortages.

Factors Affecting the Conversion Cost

The cost of converting a prime power diesel generator to natural gas can vary widely depending on several factors.

Generator Size

The size of your generator is one of the biggest factors. Larger generators typically require more complex conversion kits and more labor to install. A small generator, say under 100 kW, might be relatively inexpensive to convert. You could expect to pay anywhere from $2,000 to $5,000 for the conversion kit and installation. On the other hand, a large industrial generator over 1 MW could cost upwards of $20,000 or more. The larger the generator, the more components need to be modified, and the more time and expertise are required.

Conversion Kit Quality

The quality of the conversion kit you choose also plays a big role in the cost. There are different brands and types of conversion kits available on the market. A high - quality kit from a well - known manufacturer will usually cost more, but it will also be more reliable and efficient. Cheaper kits might save you money upfront, but they could end up costing you more in the long run if they break down or don't perform as well. You can expect to pay between $1,000 and $10,000 for a conversion kit, depending on its quality and the size of the generator it's designed for.

Labor Costs

Labor costs can vary depending on where you are and who you hire to do the conversion. In some areas, labor might be relatively cheap, while in others, it can be quite expensive. A professional technician with experience in generator conversions will usually charge more, but they're more likely to do the job right. Labor costs can range from $1,000 to $5,000, depending on the complexity of the conversion.

Additional Equipment

In some cases, you might need to purchase additional equipment to make the conversion work. For example, you might need a natural gas regulator, a fuel line, or a control system. These additional items can add a few hundred to a few thousand dollars to the total cost of the conversion.

A Breakdown of the Costs

Let's break down the costs for a medium - sized prime power diesel generator, say around 500 kW.

  • Conversion Kit: A good - quality conversion kit for a 500 kW generator might cost around $8,000.
  • Labor: Professional installation could cost around $3,000.
  • Additional Equipment: You might need to spend another $1,000 on things like a regulator and fuel line.

So, in total, you're looking at around $12,000 for the conversion.

Is It Worth It?

Now, the big question is, is it worth the cost? Well, that depends on your specific situation. If you're using your generator frequently and diesel prices are high, the cost savings from using natural gas could offset the initial conversion cost in a relatively short period. You'll also be doing your part for the environment by reducing emissions.

On the other hand, if you only use your generator occasionally, the cost of conversion might not be worth it. You'll need to do some calculations based on your usage, fuel prices, and the cost of the conversion to determine if it makes sense for you.
