About Opra

OPRA develops, manufactures and services state of-the-art gas turbine systems, and is headquartered in Hengelo, The Netherlands. Our advanced turbine technology has turned the OP16 Gas Turbine into a masterpiece of technology allowing us to serve  global markets with clean, distributed energy solutions. Setting the standard in terms of availability, reliability and low maintenance costs, OP16 Gas Turbines allow for very cost-effective ‘always-on’ generation of electricity and heat. Thanks to its unique combustion technology, OP16 Gas Turbines can even turn dirty fuel gas that would otherwise be flared, vented, or simply wasted into green power and clean exhaust gas. We are convinced that OPRA’ gas turbine systems will continue to be a structural component of tomorrow’s green energy landscape, and drive the world’s energy transition!

OPRA's Story

The history of OPRA Turbines

OPRA was founded by Jan and Hiroko Mowill in 1991. Jan Mowill had previously led the gas turbine division at a major Norwegian industrial conglomerate where he developed and commercialized the world’s first radial gas turbine engine for industrial applications in 1964. Upon the establishment of OPRA (Optimal Radial Turbine), Jan and his team worked tirelessly to develop and engineer the OP16 Gas Turbine. By 1994 the original ultra low-emission combustor was already developed and patented as a result of successful testing. By 2003 the low-emission can combustion development had started.

After a successful demonstration of the OP16 in RuhrGas (Dorsten, Germany), OPRA sold its first commercialized OP16 Gas Turbine Package in 2005. OPRA continues to drive the world’s energy transition with over 140 gas turbine generator sets world-wide, accumulating over 2 million operating hours. Since August 2017, OPRA Turbines has since opened a new state-of-the-art headquarter facility in Hengelo (NL) to further strengthen and increase production and testing capacity following recent growth in business, paving the way to becoming the leading provider of clean gas turbines for distributed energy solutions.

OPRA's Mission:
To drive the world’s energy transition

”OPRA has solutions available today to make existing operations more climate-friendly, like electricity generation from flare gases in the oil & gas sector or from a wide range of waste gases in the industry, it can also burn the zero CO2 emission fuels of the future, like green hydrogen or green methanol.”  Wim Janssen, CEO

OPRA's Vision:
To be the leading provider of clean gas turbines for distributed energy solutions
