A cleaner & cheaper alternative to diesel generators

Our generators can be deployed for a wide variety of uses, to support:

  • Growing commercial and industrial businesses
  • Construction and infrastructure projects
  • Developers awaiting main grid connection
  • Data centres
  • Businesses limited by a constrained grid
  • Plus much more

Capstone Gas Turbine Generators

This is possible thanks to Capstone microturbine power generation technology. These gas-powered microturbines are not only highly efficient and reliable, but are also an environmentally friendly alternative to internal combustion engine generators, with emissions even lower than Medium Combustion Plant (MCP) Directive targets for both NOx and SOx

There are already over 9,000 Capstone microturbines installed globally and this number continues to rise, as more and more commercial businesses become aware of the benefits of utilising this leading technology. Many of the Fortune 500 top global companies use Capstone products.

Why is there a need for a low NOx alternative to diesel generators?

Commercial and industrial projects have traditionally used temporary power systems such as diesel generators. However, requirements often stray far beyond six months, resulting in excessive costs for power.

In addition to paying more, traditional temporary power solutions don’t always have the desired reliability or environmentally compliant performance, especially in light of the recent MCP Directive.

200 kVA - 20,000 kVA power generation

Capstone microturbines are a modular solution, meaning that they have the flexibility to support a wide range of power requirements, typically ranging from 200 kVA right the way through to 20,000 kVA (approximately 200 kW to 20 MW).

Key benefits summary...

Ideal for medium and large capacity generator needs, our turnkey solutions (incorporating Design, Build, Finance, Operation and Maintenance) offer a number of unique benefits:

Cost Effective

  • Commercially viable versus traditional diesel generation
  • Simple financing to enable rental / hire via a straightforward energy services contract
  • Significant funding lines available, to support either single or multiple projects of varying sizes


  • 92% lower NOx emissions than diesel (18 mg/nm3 vs 195 mg/nm@15% O2)
  • Environmentally compliant, going beyond Medium Combustion Plant (MCP) Directive targets for both NOx and SOx 
  • Clean exhaust, with high levels of oxygen content compared to conventional generational methods (17-18% O2 content)
  • Quiet operation, with just 65 dba (decibels) at 10 meters


  • 4,000 hour service intervals standard across all microturbines
  • Reduced dependency on the grid, eliminating the risk of black or brown-outs
