MHPS gas turbine fleet achieves one million commercial operation

J Series Gas TurbineMitsubishi Hitachi Power Systems’ (MHPS) J-Series gas turbine installed fleet has reached one million hours of commercial operation

This gas turbine series is set to meet new and higher standards for reduced carbon emissions. Introduced in 2011, the J-Series delivers an industry-leading overall reliability of 99.3 per cent. The air-cooled JAC model delivers 99.5 per cent reliability and efficiency greater than 64 per cent. To put this in context, the mature F-class gas turbine fleet has a reliability of 98.6 per cent and a combined cycle efficiency of 57-59 per cent.

Forty-three J-Series gas turbines are in commercial operation, and total ordered capacity exceeds 25GW globally. One hundred units have been technically selected in Brazil, Canada, Japan, Mexico, Peru, South Korea, Taiwan, Thailand and the USA.

In the Middle East and North Africa, with similar technical selections and with achieving lowest tariffs in some of the region’s biggest and most iconic IPP project tenders, the J/JAC machines provide the region’s power industry with best-in-class performance. This includes attaining record low cost of energy, emissions reductions, as well as setting the highest standards for operational flexibility and power supply security and stability.

Akimasa Muyama, senior executive vice-president and chief technology officer of MHPS, said, “As we reflect on the important milestone of achieving one million operating hours with our J-Series gas turbine, we know that the most important part of that accomplishment is that we ran for all those hours with 99.3 per cent reliability.”

Recent innovations to the J-Series target further reductions in carbon emissions. This month the company received an order from the Intermountain Power Agency, in Delta, Utah, for two JAC gas turbines capable of using up to 30 per cent renewable hydrogen fuel. Eventually, these turbines will be capable of using 100% renewable hydrogen fuel. While a 30 per cent Hydrogen fuel mix can eliminate one million tonnes of CO2 emissions per year for a typical gas-fired plant of 1100-1200MW size, the 100 per cent hydrogen system will eliminate carbon emissions entirely.

Paul Browning, president and CEO of MHPS Americas and newly appointed chief regional officer for Europe, Africa and the Middle East, commented, “Going forward, every gas turbine MHPS sells globally will have renewable hydrogen fuel capability. This allows our customers to purchase a natural gas power plant today and convert it over time into a renewable energy storage facility.”
