Microturbines offer a cleaner and more cost-efficient generator solution. Here you can learn more about the technology and why we exclusively use industry-leading Capstone gas microturbines to meet temporary power requirements throughout the UK and Ireland.

Microturbine FAQs

A microturbine is a well-established technology in the distributed generation world. It is essentially an aero turbine powered by gas or other fuel that produces electricity (and heat, if required) on a relatively small scale. A microturbine works in a similar way to a jet engine, albeit producing electricity rather than a thrust.

The technology has a number of distinct advantages over many power generation methods, including:

  • Improved reliability
  • Lower emissions
  • Reduced energy waste
  • Reduced maintenance cycle

The numerous financial, environmental and operational merits of microturbines have resulted in a progressive increase in their adoption over the past decade, with Capstone in particular leading the sector.

Founded in 1988, and a UL-Certified ISO 9001:2015 and ISO 14001:2015 company, Capstone Turbine Corporation is the world’s leading developer and manufacturer of clean and green microturbine power generation systems. Evolved from the advanced development of aero turbine technology, Capstone microturbines offer one of the cleanest and most efficient distributed generation solutions available.

Capstone’s technological advantages and vertical market strategy have enabled it to strengthen its position as the global leader in clean and green power generation technology, so much so that many of the Fortune 500 top global companies use Capstone products.

Capstone has shipped over 9,000 microturbines to customers in multiple vertical markets worldwide. These innovative and award-winning turbines have logged millions of documented runtime operating hours, delivering a capacity in excess of 850 MW.


Capstone microturbine power generation systems comprise advanced engineering, with more than 100 patents. By integrating an aero-based turbine engine, a permanent magnet generator, advanced power electronics and patented air bearing technology, Capstone turbines are highly efficient, reliable and environmentally friendly. The following are the key features and benefits of deploying a Capstone microturbine:

These microturbine solutions are modular, meaning that they can be installed individually or in a ‘multi-pack’ configuration. Accordingly, they can provide scalable power generation solutions, from 65 kVA to 10+ MVA.

The microturbines can operate on a variety of gaseous or liquid fuels, including natural gas, associated gas, LPG/propane, flare gas, landfill gas, digester gas, diesel, aviation fuel and kerosene.

The turbines require a small amount of electricity upon start-up and there is a small parasitic load used for the gas compressors and ancillary equipment.

Capstone microturbines are extremely quiet, emitting a faint whirring sound rather than a thudding noise.

They emit 65 dba (decibels) at 10 metres, which is generally much quieter than reciprocating engines and this is due to the fact that the microturbine emits sound at a high frequency (because it’s a turbine), whereas reciprocating engines have a low frequency.

The turbines are ideal as power generators but, in many global installations, they are actually the permanent, primary power source, and this can certainly be the case if the customer requires this.

What’s more, the microturbines certainly aren’t limited to simply providing power. Due to their versatility, they are often deployed to deliver both electricity and heat in the form of hot water, hot air, steam or refrigeration in Combined Heat and Power (CHP) and tri-generation (CCHP) applications, across a range of industries globally.
