Helping Electrify Indonesia

By Mike Brezonick19 July 2017

GE announced that its largest and most efficient gas turbine, the 9HA.02 will be used at the Tambak Lorok combined cycle power plant in Semarang, Indonesia. Operated by Indonesia Power, the Tambak Lorok facility will be the first in in the island nation to use 9HA.02 technology to bring 780 MW to the Indonesian grid — enough electricity to power the equivalent of more than 5 million average Indonesian homes, GE said.

Available in outputs exceeding 510 MW per unit, the air-cooled 9HA.02 is a four-stage turbine with a 3D aerodynamic hot gas path, cooling and sealing improvements, single-crystal and directionally solidified blades and double-wall casing for improved clearance control. The 14-stage compressor section utilizes superfinished 3D aerodynamic airfoils with three stages of variable stator vanes, and field-replaceable blades. The DLN 2.6+ combustor with axial fuel staging has been proven through 45,000 starts and more than two million operating hours, GE said.

In a related announcement, GE Power Services will provide 15 years of maintenance and services for the  Tambak Lorok facility.

The Tambak Lorok news came on the same day that the future of Indonesia’s power generation infrastructure were discussed at ‘Powering Indonesia,’ a conference organized by GE and co-hosted by PLN and MKI to discuss future challenges and opportunities for the country’s energy ecosystem. Senior government officials, including Sofyan Basir, president director of state-owned power company PT Perusahaan Listrik Nasional (PLN), attended the event in Jakarta, which also included more than 300 public and private sector energy industry leaders and experts.

GE’s 9HA.02 gas turbine moves to the test stand. Along with supplying the turbines, GE Power Services will also provide 15 years of maintenance services at the Tambak Lorok plant.

“Our technology, service capabilities and digital solutions are redefining the possibilities for energy in Indonesia and changing the way power is generated, delivered and maintained,” said Handry Satriago, CEO of GE Indonesia.  “Together with our forward-thinking Indonesian partners, we are leading the digital industrial evolution of power in the country – with projects that set new standards in efficiency, reliability and innovation and can serve as models for national energy companies and regions with challenging and remote geographic conditions.”

The adoption of digital technologies to enhance and optimize Indonesia’s energy assets and networks, combined with the deployment of the most efficient gas turbines, ultra-super critical coal technology and the upgrading of existing plants and transmission and distribution networks, are all expected to provide Indonesia with substantial savings and significant reductions in carbon emissions and help achieve Indonesia’s goals for energy efficiency, reliability and sustainability, GE said.

The conference also saw agreements being announced with PT Pembangkitan Jawa-Bali (PJB), PT Indonesia Power and the Ministry of Villages, Disadvantaged Region Development, and Transmigration. PJB operates 21 facilities including steam, gas and distributed power with a total generating capacity of 10.7GW. PJB’s goal is to double its capacity to 22 GW by 2022.

Under the multi-year agreement, GE will deploy its Asset Performance Management (APM) and Operations Optimization (OO) solutions across PJB’s 21 sites, as well as establish a GE-designed Remote Engineering, Monitoring, Diagnostics and Optimization Center in Surabaya, with a second Engineering Center planned for Jakarta.

 GE and PJB will also collaborate on the development of next generation applications using GE’s Predix platform for the Industrial Internet. In addition to being the first Indonesian deployment of GE’s digital solutions to increase reliability and efficiency in power generation, transmission and distribution, the use of digital technology by PJB across its remote facilities provides an opportunity to uncover unknown inefficiencies and unlock values overlooked in the system.

Finally, GE also signed a Memorandum of Understanding (MOU) with the ministry on the implementation of a rural electrification program.  This will involve collaboration by both parties on the planning of the program’s development with GE providing support in power generation technology across its portfolio of distributed power solutions that include hybrid gas or diesel with photovoltaic, renewable power plants as well as digital power solutions and microgrid solutions.

The technology assessment is expected to address challenging environment across 13,000 remote, disadvantaged, outer, boarder and transmigration villages being scheduled by the ministry for deployment commencing in 2018.
