Smart Investments in Power Generation:

The Right Fuel Source That Can Actually Lower Capital Expenses

Diesel generators have earned and maintained a long-standing reputation for being a power generation workhorse – bulky, noisy, a little smelly, but overall fairly reliable.

Recent advances in natural gas technology, however, are starting to topple diesel’s dominance. Natural gas gensets – quieter, cleaner and more efficient – present a sleek and increasingly popular alternative to diesel. They’re quickly redefining the power generation industry in much the same way Tesla and electric cars redefined the automotive industry.

PRAMAC Gaseous Genset

The ecological benefits of natural gas versus diesel are obvious. Natural gas burns significantly cleaner; produces lower emissions of sulfur, nitrogen and carbon dioxide into the atmosphere; and lacks the strong, distinguishing diesel odor. But those benefits alone aren’t enough to justify a natural gas system if the costs are prohibitive, which they’ve been in the past.

With today’s technology, however, natural gas systems like the gaseous product line from PRAMAC, one of the world’s largest suppliers of power generation equipment, are actually able to lower capital expenses over a system’s lifetime compared to traditional diesel generators.

This article will highlight the benefits of natural gas gensets, demonstrate how these benefits reduce capital expenses, and discuss how to team up with an engineering support partner like Generac to tailor a system to the needs of your specific application.

Natural Gas – Clean & Reliable

Working with natural gas was somewhat problematic until a few years ago when new technologies increased the durability and reliability of these gensets.

Natural gas generators have a comparatively limited power output. This means an individual natural gas generator generally cannot match the wattage of its diesel counterpart. However, when you install multiple natural gas generators together in parallel configuration, not only can they produce a comparable or even greater amount of power, they also offer flexibility, scalability, and a numerous additional benefits detailed below.

  • Easier Permitting: Natural gas is a clean burning fuel that does not require excessive testing or permitting. The high level of emissions produced by diesel generators often increases the difficulty in procuring an air-quality permit.
  • Long Running Times During Outages: Since natural gas is supplied by a utility with underground pipelines it is rarely impacted by weather and the flow of fuel is largely secure—they can often run for weeks and months. For diesel generators, the fuel supply typically ends after three days. And during a crisis, fuel deliveries are often delayed or non-existent.
  • Low Maintenance: In diesel generators, the required low sulfur diesel gas needs to be re-conditioned or polished every 12-16 months to ensure impurities don’t impact fuel flow. This is not an issue with natural gas.
  • Cost-effective Engines: Automotive-style spark-ignited engines are readily available in high volumes, making them more economical than similarly sized diesel engines.
  • Reliable Fuel Supply: With diesel fuel, winter storms or unexpected disasters can wreak havoc on operations across the country. If supply trucks are delayed, it can greatly impact production.
  • Overall Eco-friendliness: Many companies are becoming very “green” and considering that aspect in every part of new construction or as they remodel. Natural gas is the cleanest burning fossil fuel today, it produces the fewest emissions, and has a much smaller carbon footprint. Natural gas generators also avoid the fuel containment, spillage, and environmental concerns associated with storing diesel fuel.

Lower Total Cost

In the past, natural gas generators came with a hefty price tag. Today, however, the technology has become much more accessible and affordable. In fact, many natural gas gensets now offer a significantly lower total cost of ownership (TCO) than their diesel counterparts.

Technology enhancements create efficiencies that translate to cost savings in nearly every aspect of the product lifecycle – from installation to maintenance to fuel cost. Some of the primary cost reduction benefits are detailed below.

  • Capital Investment: The ability to add additional paralleled generators into your system over time can mean a significant reduction in your initial capital investment. There is no need to install more power than currently needed, since more modules can be added in the future as business grows or power requirements increase.
  • Installation Cost: The capital investment to specify and install two paralleled lower-kW generators compared to one larger-kW generator can be similar. However, paralleled units often have the advantage of greater installation support from the supplier, which offsets some of the initial cost. Their lighter weight makes them easier to move and place on job sites, requiring smaller, less expensive lifting equipment, and the simple design means installation time is decreased.
  • ​Fuel Cost: In many Countries, the cost of natural gas trends significantly lower than that of diesel.
  • Servicing and Maintenance Cost: A single paralleled unit can be taken out of service for maintenance or repair while other units remain available should an outage occur. Smaller paralleled generators can also be stored in easier-to-access locations like on rooftops or in parking garages.

Diesel generators had a good run. But it might finally be time for you to put the old workhorse out to pasture and team up with a manufacturer like PRAMAC to evaluate your natural gas options and start reducing your expenses.
