As the country’s energy structure and industry landscape evolves, it is setting requirements on cogeneration, says Yang Dan, president of GE Power China

GE Power has announced the conclusion of several milestone projects in Asia.

It has celebrated the commercial operation of China Huaneng Group’s Huaneng Guilin Gas Distributed Energy Project, using three 6F.01 turbines.

The project marks the first 6F.01 gas turbines in operation globally and builds on GE’s already strong 6F gas turbine performance in China, with more than 30 units operating commercially.

“The project marks a breakthrough for many, as the first-ever gas power project for the city of Guilin and the first-ever distributed energy project by China Huaneng Group,” said Li Xiaodong, general manger of Huaneng Guilin Gas Distributed Energy Co.

“With GE, we are advancing the city’s smart energy intiatives, supplying high-efficiency and cleaner energy, and supporting the city’s ambition to increase prosperity.”

Guilin, in Guangxi Zhuang Autonomous Region, is a world-famous tourism destination in China, known for its incredible natural landscape. As it is developing industrially, the city is not only looking for cleaner energy, but also a modern and efficient heat supply for many businesses including life science, pharmaceuticals and technology industries.

Featuring an innovative combined cooling, heating and power (CCHP) configuration, the project will be capable of self-determining its electricity output based on heat demand while also supplying heating and electricity to nearby factories. It is also capable of providing heating and cooling to surrounding public, commercial and residential areas. These benefits, centred around the 6F.01 technology, will help the region see more reliable, cost-effective and flexible power for many years.

“China is at the dawn of a major boom in gas distributed energy, and as China’s energy structure and industry landscape evolves, the country is setting requirements on cogeneration,” said Yang Dan, vice-president of GE and president of GE Power China.

“From design and manufacturing to installation, our global and local teams are joining hands to provide timely, reliable and customizable solutions to make 6F.01 a good fit to the market. With a strong commitment in localization, we will continue to create more value for customers and contribute to cleaner, safer and more efficient power systems.”

With advanced materials and technologies adopted from GE’s successful H- and F-class gas turbines, the 6F.01 boasts an industry leading combined-cycle efficiency of 57 per cent and fuel utilization rate of 81.15 per cent. The turbine is also the most efficient 50 MW gas technology and has the best heat cogeneration capabilities in its class, making it an ideal choice for gas distributed energy projects.

Malaysia CCPP

GE Power Services has signed a 21-year deal with Malaysia’s Southern Power Generation for a 1440 MW combined-cycle power plant.

The Track 4A plant in Pasir Gudang, Johor, is under construction and under the terms of the agreement, GE will provide services solutions for two GE 9HA.02 gas turbines – the first to be installed in Malaysia.

It will also deploy its Predix Asset Performance Management (APM) software to help improve the plant’s visibility, reliability and availability and also utilize its Fleet360 platform of gas plant solutions.

“With the largest base of installed gas turbines in Malaysia, GE has grown hand in hand with the country’s power development needs,” said Ramesh Singaram, president of GE Power APAC.

The agreement also includes GE’s Predix APM suite of digital solutions. APM improves asset visibility, reliability and availability and reduces operating and maintenance costs: data processed by the APM solution can help balance maintenance costs, improve inspection intervals and provide invaluable insights into operational risks.

Data collected from sensors throughout the facility will be monitored at GE’s Monitoring & Diagnostics (M&D) Center in Kuala Lumpur. The plant will be jointly constructed with Taiwanese EPC partner CTCI Corporation. It will consist of two generating blocks, each equipped with a 9HA.02 gas turbine, generator and heat recovery steam generator from GE.

Yokohama project

GE’s Power Services has also announced that its largest ever flange-to-flange (F2F) replacement project in Japan was successfully completed on time at Block 7 and Block 8 of TEPCO Fuel & Power’s Yokohama plant in Japan.

GE said the project is expected to save approximately $71 million in annual fuel costs.

The project involved a total of eight gas turbines ranging from 9FA.01 to 9FA.03 models being upgraded to improve performance and reduce lifecycle cost for TEPCO.

GE’s solution enabled TEPCO to incorporate all gas turbine replacements and upgrades to the latest technology at minimal disruption to plant operations. It achieved increased total plant output of gas turbine combined cycle by 216 MW and improved efficiency of 1.7 per cent under customer load conditions. It also lowered emissions by 30,000 tonnes annually per unit.

In a flange-to-flange replacement exercise, the entire engine from inlet flange to exhaust flange is replaced as one piece. This addresses multiple power generation needs at once, including asset life extension, performance recovery, emissions controls, and fuel flexibility.

In addition to the gas turbine upgrade at the Yokohama plant, GE also successfully completed the world’s first 9EMax four-stage gas turbine at TEPCO’s Futtsu plant in Chiba. The now completed upgrade is the first of a total of six 9EMax upgrades to be implemented at the plant and is expected to increase output, improve thermal efficiency from 47.2 per cent to 51.4 per cent and reduce emissions.
