GE Jenbacher Gas Engine Variety of gas fuels can be used
Landfill gas
Sewage gas
Petroleum gas
Specialty gas
Biogas (methane fermentation)
Wood gas
Natural gas
Coal mine gas
Emergency power
Jenbacher: LEANOX lean burn combustion
control system
The Jenbacher gas engine measures electric output,
MAP for air/fuel, and air/fuel temperature after the
intercooler. The air/fuel ratio is controlled with
LEANOX control in real time.
• Can operate on pyrolysis gas from woody
biomass that has large fluctuations in
calorific value.
• Can be used with hydrogen-rich gases.
• Can control generation of NOx.
Highly backfire-resistant to unstable fuels

CPV Sentinel: 8 LMS100 turbines Site Features
• Ability to generate a wide range of power from 50 MW to 800 MW.
• Starts up within 10 minutes. Power control of 400 MW/minute.
• Power supply for various applications (spinning reserve, peak cuts, etc.)
• No decline in output even at high temperatures with the installation of intake air cooling systems.
• Conforms to strict environmental regulations. Does not use water for reduction of NOx. Reaches 2.5 ppmvd (NOx)/5 ppmvd CO within 10 minutes after startup. High-efficiency, simple cycle plant (800 MW) supports
the stable operation of 3,000 wind turbines in the harsh environment of California.

•Ability to generate power only when necessary (optimized for
multiple starts per day).
•Load following capacity of 50 MW/minute/unit: Ability to go from 50%
load to 100% load within 60 seconds.
•Achieve high efficiency even with partial loads: Operable at high
efficiency of 50%-100% (50 MW to 100 MW).
•High flexibility to support frequency fluctuations: Ability to support
fluctuations up to a maximum of 5%.

Achievements for the Sochi Olympics
Two LMS100PB turbines were used
Reasons for selecting the LMS100
- World’s most efficient gas turbine (World’s most efficient, simple-cycle gas turbine on the market. … by CEO of Inter RAO) -High load following capability (50 MW/minute) - Shorter maintenance times compared with other machinery
Overview
Client: Inter RAO (One of Russia’s largest power companies) Site: Dzhubginskaya power plant Equipment: LMS100PB x 2 Max. output: 200MW

Diversification of Fuels (Gas & Liquid Fuel)
Gas
Liquid Fuel
LMS100 can use both gas and liquid fuel. The LMS100 is highly flexible and can use gas for normal operations and liquid gas in emergencies.
The following gases can be used. Gas with sufficient calorific value Gas maintained in gaseous state Pure gas
Most LNG (including share gases) can be used in the LMS100.
The following liquid gases can be used. Liquid fuel with sufficient calorific value. Liquid fuel that can be sprayed Pure liquid fuel
Heavy oil (corresponding to Class A heavy oils), kerosene, and light oil can be used in the LMS100.
Case Study #2

Removing the Barriers to RE Development in Japan
Changes in the environment surrounding energy can be “irregular.”
Diversification of power sources and technologies, as well as portfolio
management, is important.
Technological innovation requires time, money, and long-term strategies.

Our surrounding environment
Formulation of grand designs by the national and local governments, as well as continuous verification and revisions, are necessary.
Careful consensus building is needed to determine who will bear the costs
when introducing new and renewable energy. Programs to support policies and promote technological innovation for specific
purposes are necessary (New Sunshine Plan?).
The industry is still in the early developmental stage, and therefore, should actively bring in examples from overseas, in particular the opinions of
businesses.
