GE Energy
Product SnapshotThe FlexEfficiency 50 Combined Cycle Power Plant is GE’s latest innovation in gas turbine technology, engineered to deliver cleaner,
more efficient energy onto the power grid and into our homes. The first product in GE’s new FlexEfficiency portfolio, the FlexEfficiency
50 plant will enable the integration of more renewable resources onto the power grid by combining flexibility and efficiency to rapidly
ramp up when the wind is not blowing or the sun is not shining, and to efficiently ramp down when they are available.
Enabling RenewablesDemand for renewable energy is growing. As additional renewable sources join the grid, reliable power generation and stress on the
grid both become larger issues. GE’s new natural gas-driven plant can accelerate the widespread adoption of renewable power
generation around the world. Its flexible, jet engine-based technology addresses variability, reliability, and the need for lower fuel use
and operating costs. The FlexEfficiency 50 plant does this while simultaneously helping utilities take advantage of the growing trend
to use abundant, cleaner-burning natural gas for power generation.
Product Attributes
GE FlexEfficiency* 50 Combined Cycle Power Plant fact sheet
Efficiency The FlexEfficiency 50 plant is rated at 510 megawatts with greater than 61% efficiency, significantly
reducing the amount of fuel needed to create power. The plant:
• Provides greater than 61% base load efficiency and maintains highly-efficient operations even when
ramped down
• Can be integrated with a concentrated solar power field to achieve more than 70% efficiency
• Has a 10% smaller footprint than existing combined cycle power plants with equivalent output
• Offers a cleaner, simpler design that enables easier maintenance and increases reliability
Flexibility Flexibility refers to a power plant’s ability to respond to varying grid demands. Key flexibility attributes
of the FlexEfficiency 50 plant are:
• Achieves a ramp-rate of more than 50 megawatts per minute, twice the ramp-rate of today’s industry
benchmarks
• Allows the plant to turn down to 40% of its load while maintaining emissions guarantees
• Starts in less than 30 minutes
FlexEfficiency FlexEfficiency is the powerful combination of efficiency and operational flexibility. GE believes owners and
operators can generate electricity more cost-effectively if they include flexibility and efficiency
considerations in their evaluation models, and has termed this concept “FlexEfficiency.” FlexEfficiency is
defined as profitable annual MWHr’s divided by annual fuel consumption. In the way that a car’s actual fuel
efficiency is the combination of its highway and city fuel efficiencies, FlexEfficiency represents a power
plant’s efficiency over a variety of operating conditions.

GEA18787 (05/2011)
fact sheetCombined Cycle Plant A combined cycle plant uses gas and steam turbines working in tandem to make efficient use of fuel. The
FlexEfficiency 50 plant includes a highly flexible and efficient gas turbine that generates both electricity
and heat. The electricity is fed onto the power grid, and the heat, which is typically wasted in other power
plants, is used to create steam. That steam is used to drive a highly efficient steam turbine that creates
additional electricity to feed onto the grid. The efficiency of combined cycle plants ultimately creates
cleaner energy.
Economic andEnvironmental Benefits
The plant delivers significant cost-savings for the customer and reduction of plant emissions when
compared to GE’s current technologies. A typical plant that varies its output depending on conditions
will achieve these benefits:
• Savings of approximately $2.6 million dollars per year under a typical operating profile of 4,500 hours
per year at a natural gas price of about $10 per million btu
• Annual fuel savings of 6.4 million cubic meters of natural gas, equivalent to the annual natural gas
consumption of more than 4,000 EU households
• Annual CO2 emissions reduction of more than 12,700 metric tons, equivalent to removing more than
6,000 cars from EU roads. Each plant also avoids 10 metric tons of NOx annually
The technology is ecomagination certified, which is a rigorous third-party certification recognizing the
plant’s environmental and economic benefits to customers.
Manufacturing GE has invested more than $500 million in R&D to develop the FlexEfficiency 50 plant. The launch follows
GE’s recent announcements of the world’s most efficient wind turbine, the highest reported efficiency
for thin film solar, and $11 billion in acquisitions that strengthened a portfolio supporting natural gas and
power transmission.
The FlexEfficiency 50 plant is the first product in GE’s new FlexEfficiency portfolio, and part of GE’s
ecomagination commitment to drive clean energy technology through innovation and R&D investment.
Testing The gas turbine for the FlexEfficiency 50 plant will be tested in GE’s full-speed, full-load testing facility.
• GE is investing $170 million to create the testing facility.
• The gas turbine will be tested at full capacity in a variety of real-world power plant conditions prior
to commercial operation.
• The plant can be tested beyond normal operating parameters because the facility is not connected
to the power grid.

GE Energy
The Mark* VIe control is GE Energy’s vehicle for delivering the
fence-to-fence system solutions you need for performance,
operability, and availability in today’s combined cycle facilities.
GE uses the Mark VIe Integrated Control System (ICS) to reduce
project risk and improve operability. For this reason, end users
and engineering procure constructors (EPCs) can also use the
ICS. When GE Energy is responsible for a turnkey power plant, it
relies on the ICS for total plant control.
The controller is Energy’s control platform for a wide range
of applications from wind, hydro, gas, and steam turbines,
to complete power plant controls, including nuclear power
plants. In a combined cycle application, it provides a common
control and protection system for the gas turbines, steam turbine
generators, heat-recovery steam generators (HRSG), and the
balance-of-plant (BOP) equipment.
While a common hardware platform reduces spare parts costs, the
real value is in the level of system integration achieved by having
a single control system for all plant equipment. The operator’s
productivity and operational awareness is increased through
a common interface to all of the equipment operator screens,
process data, alarms and events, trips, and trend data. The system
tools can analyze data more thoroughly with the single database.
Traditional integration of plant and unit level controls is eliminated.
This reduces system complexity, start up problems, commissioning
time, and project risk. All of these features contribute to simplified
life-cycle maintenance and training for the plant equipment and
personnel.
GE Energy’s combined cycle plant design expertise coupled with
advanced controls extends the benefits to plant-wide operational
enhancements. Examples include model predictive control to
manage steam turbine stresses, reducing the time for the gas
turbine during start up to reach full load and emissions compliance,
and advanced analytic algorithms accommodating the increased
variability in fuel sources. The Mark VIeS safety version is SIL3-certified
and available for burner management, emergency shutdown, or
life safety systems.
ExperienceThe Mark VIe controller was developed as an enhancement
to, and building on the success of, the Mark VI control system.
The Mark VIe controller is now the standard for turbine and
plant controls.

Mark VIe Controller and I/OMark VIe controller has a flexible and scalable architecture. In
combined-cycle applications, dual redundant controllers and
simplex I/O are typically used for the Distributed Control System
(DCS). Triple redundant controls are used for turbine controls and
safety systems. Distributed I/O modules communicate on
redundant 100 MB Ethernet, and can be clustered together in a
central area or distributed throughout the plant. I/O modules can
operate from –30 to 65°C (-22 to 149 °F) and time stamp discrete
inputs to ±1 ms for sequence of events reporting. I/O modules
support HART®, FOUNDATION™ fieldbus, PROFIBUS™, and
Modbus® protocols.
Diagnostic LEDs are provided on each module, and messages
are available to operator stations. If a fault occurs, controllers
and I/O modules can be replaced online to maximize system
availability. Network diagnostics are reported in the alarm
management system.
Operator and Engineer WorkstationsThe ControlST* software suite comprises several high performance
tools for ease-of-use by operators and maintenance personnel.
These tools include the WorkstationST* application for
management of HMI and Historian functions, and the ToolboxST*
application for configuration and diagnostics. These tools
are common across the turbine, HRSG, BOP, EX2100 Excitation
control, LS2100 Static Starter control, and the Mark VIeS safety
controller. ControlST software provides direct connectivity from
parameters on operator screens to their corresponding alarm
history, trends, logic diagrams, watch windows, and browsers.
You can use the drag-and-drop feature to move alarms and data
on SAMA-type logic diagrams to trends for analysis.
Configuration of logic screens with faceplates and permissives
are integrated to minimize the time required to make system
changes or add new equipment.
Asset ManagementGE Energy offers a fully integrated set of solutions for combined-
cycle plants including solutions for real-time optimization of
equipment and selected processes, condition monitoring, and
event diagnostics. A broad range of data sources can be

GE Launches Power Plant with Breakthrough Flexibility and Efficiency to Enable Greater Use of Wind, Solar and Natural Gas on Power Grid
Cleaner Energy through New Combination of Jet Engine and Gas Turbine Technology
New Plant Offers Greater than 61 Percent Efficiency and Unprecedented Operating Flexibility Technology Enables Further Deployment of Renewables Like Wind and Solar New Power Plant Represents First Product in GE’s New FlexEfficiency* Portfolio Technology Introduced Today in Paris, 2 p.m. CET; View the Live Webcast at www.ge-flexibility.com
PARIS, FRANCE—May 25, 2011—GE (NYSE: GE), whose technology helps to deliver a quarter of the world’s electricity, today announced a first-of-its-kind power plant engineered to deliver an unprecedented combination of flexibility and efficiency. By rapidly ramping up and down in response to fluctuations in wind and solar power, the technology will enable the integration of more renewable resources into the power grid. The FlexEfficiency* 50 Combined Cycle1 Power Plant is rated at 510 megawatts and offers fuel efficiency greater than 61 percent. The plant is the result of an investment of more than $500 million in research and development by GE and a key part of its ongoing work to create and manufacture technologies around the globe that deliver cleaner, more efficient energy.
While power plants today can provide flexibility or high efficiency, this power plant will deliver an unprecedented combination of both. GE calls this combination of flexibility and efficiency ‘FlexEfficiency,’ which is essential if renewable power is going to cost-effectively integrate into power grids around the world on a large scale.
GE drew from the company’s jet engine expertise to engineer a plant that will ramp up at a rate of more than 50 megawatts per minute, twice the rate of today’s industry benchmarks. Operational flexibility at these levels will enable utilities to deliver power quickly when it is needed and to ramp down when it is not, balancing the grid cost-effectively and helping to deploy additional renewable power resources like wind and solar. A typical FlexEfficiency 50 plant will deliver enough energy to power more than 600,000 E.U. homes.
Increasing Renewables with Natural Gas
“As our customers seek to increase their use of renewable energy, the challenge of grid stability sharpens. They are under added pressure to achieve higher levels of efficiency and lower emissions for natural gas power plants. The FlexEfficiency 50 plant creates an immense growth opportunity in a new segment for our gas turbine technology and is in lock-step with our commitment to build a cleaner energy future,” said Paul Browning, vice president—thermal products for GE Power & Water. “For years we have been working to develop technology that can, in the same breath, deliver breakthrough efficiency and deal head-on with the challenge of grid variability caused by wind and solar. The need
1 In a combined cycle power plant, greater fuel efficiency is achieved because waste heat is recovered from the exhaust of the gas turbine, converted to steam and then fed to a steam turbine to provide additional energy output.
Page 2 of 3 GE May 25, 2011
for combined flexibility and efficiency is even more pressing today as countries around the world establish new emissions standards.”
The FlexEfficiency 50 plant is the first product in GE’s new FlexEfficiency portfolio and part of GE’s ecomagination commitment to drive clean energy technology through innovation and R&D investment. The launch follows GE’s recent announcements of the world’s most efficient wind turbine, the highest reported efficiency for thin film solar and $11 billion in acquisitions that strengthen a portfolio supporting natural gas and power transmission.
“Much of today’s power generation technology is serving yesterday’s power grid. Institutions and individuals everywhere are looking for cost-effective ways to use solar, wind and gas energy on a large scale. But they often assume that renewable energy can simply plug in to the existing power grid,” said Steve Bolze, president and CEO of GE Power & Water. “Throughout GE, we have invested to strengthen our global portfolio with a view to delivering efficient power generation across clean energy technologies. We expect this FlexEfficiency breakthrough to help take advantage of abundant natural gas while we simultaneously carve a fresh path to accelerate wider adoption of renewable energy, all with less impact on natural resources.”
Sustainability by Design
GE engineers were able to avoid the typical tradeoffs between flexibility and efficiency by approaching the plant design from a total equipment and control systems perspective. The FlexEfficiency 50 plant is engineered for flexible operation by integrating a next-generation 9FB gas turbine that operates at 50 Hz, which is the power frequency that is most used in countries around the world; a 109D-14 steam turbine, which runs on the waste heat produced by the gas turbine; GE’s advanced W28 generator; a Mark* VIe integrated control system that links all of the technologies; and a heat recovery steam generator.
“With global energy demand expected to double by 2030 and electricity generation accounting for 40 percent of greenhouse gas emissions, utilities and government bodies are taking a hard look at how to produce power more efficiently,” said Ricardo Cordoba, president of GE Energy for Western Europe and North Africa. “This innovation can have a dramatic effect on CO₂ emissions and offers a nimble, efficient and cost-effective way for us to help E.U. countries in their pursuit of 20-20-20 energy goals2.”
The International Energy Agency concluded in a report issued yesterday that large shares of variable renewable energy are feasible as long as power systems and markets are properly configured so they can get the best use of their flexible resources. The FlexEfficiency 50 Combined Cycle Power Plant offers unprecedented levels of flexibility that will simplify this challenge without sacrificing fuel efficiency.

GE Energy Invests in eSolar, a Key Step to Combining Natural Gas and Renewable Energy for Cleaner, More Reliable Power
GE Granted Exclusive License for Deployment of Solar Thermal Tower Technology Turkish Investor and Developer MetCap Energy Joins as Investment Partner Enables Better than 70 Percent Natural Gas Fuel Efficiency When Integrated with GE’s Recently
Announced FlexEfficiency Power Generation Technology Emerging Demand for ISCC Seen in Europe, Africa, the Middle East and the USA
HOUSTON, TX — June 6, 2011—GE Energy announced today that it has entered into an investment and licensing agreement with California-based eSolar that enables GE to deploy Integrated Solar Combined Cycle (ISCC) technology to customers worldwide. eSolar is a provider of next-generation, tower-based concentrating solar thermal technology. MetCap Energy Investments, a Turkish investor and developer of power projects, has joined GE in making this investment. “When we look at the long-term future of power generation, we see the importance of integrating natural gas and renewable energy sources in new and innovative ways to provide energy that is cleaner, more cost effective and more reliable,” said Paul Browning, president and CEO— thermal products for GE Energy. “We developed the FlexEfficiency* 50 Combined Cycle Power Plant to enable more renewables to come on the grid and to improve power plant efficiency. Our investment in eSolar is another step in our journey to transform the energy industry.” Under the agreement, GE will license and incorporate eSolar technology and software into its offers of cost-effective ISCC and standalone solar thermal power plants. The companies expect the transaction, which will establish GE as a minority shareholder, to close within a month. Financial terms are not being disclosed. An ISCC project combines a combined-cycle system including a gas turbine, steam turbine, generators and a heat recovery steam generator, with a field of mirrors that focus sunlight on a tower to produce high temperature steam. Steam generated in the solar field is fed into the water-steam cycle of the combined-cycle plant, increasing the power of the steam turbine and creating extra megawatts of electricity without using any additional natural gas. “GE has the world’s largest installed base of gas turbines that are being used in ISCC power plants, but these plants used higher cost and lower temperature trough technology and combined-cycle technology that have limitations in flexibility. Our revolutionary FlexEfficiency technology was designed from the ground up to integrate with renewable power, and the addition of eSolar‘s high temperature tower technology to our FlexEfficiency combined cycle power plant is an important step forward for our industry because it allows us to offer an ISCC power plant that creates more value for customers at a competitive cost,” said Browning. “As a part of this transaction, GE is becoming an investor in the technology as well as the primary channel to the power industry though the license arrangement.”
eSolar’s technology will be integrated with GE’s recently introduced FlexEfficiency 50 Combined Cycle technology to create a highly efficient and reliable ISCC plant. “FlexEfficiency 50 can reach more than 61 percent thermal efficiency. With the eSolar power tower add-on, an ISCC plant provides the capability to achieve better than 70 percent fuel efficiency, while providing reliable power, day or night,” said Browning. “We are very excited to partner with GE, a global company employing technology excellence in the supply of power generation equipment and services, to create cost-effective, total plant solutions for customers who are looking to meet both their energy production and environmental responsibilities,” said John Van Scoter, CEO and president of eSolar. “Combining our solar solutions with GE’s thermal power experience and large plant expertise creates a more environmentally responsible power generation solution for power producers worldwide. Compared to current baseload plants, the ISCC reduces the amount of fossil fuel required for baseload plants, which leads to reduced carbon dioxide emissions. Together, we will move ISCC significantly forward on the energy landscape.” eSolar’s power plant technology uses small, flat, pre-fabricated mirrors called heliostats to track the sun and reflect its heat to a tower-mounted receiver. This generates steam used by the plant’s power block to create electricity. Thousands of heliostats are aligned and controlled using advanced software algorithms to precisely focus the sun’s energy. eSolar’s technology is architected to provide modular fields that maximize energy production, are scalable to meet a wide range of customers’ power generation needs, while also enabling rapid, lower cost deployment.

MetCap Energy Selects GE’s New FlexEfficiency Technology for World’s First Integrated Renewables Combined Cycle Power Plant
Landmark Project will Enable more Wind, Solar and Natural Gas for Turkish Power Grid GE Technology Enables Plant Efficiency Greater than 70 Percent through Unprecedented Integration
with Wind and Solar eSolar will Provide Integrated Solar Thermal Tower Technology
MILAN, ITALY—June 7, 2011—GE’s (NYSE: GE) breakthrough FlexEfficiency* technology has been selected for an innovative new power plant being developed by MetCap Energy Investments, a Turkish project developer, the two companies announced today at POWER-GEN Europe 2011. The project will produce the world’s first Integrated Renewables Combined Cycle1 (IRCC) Power Plant.
By designing the plant from a total equipment and control systems perspective and utilizing the flexibility of GE’s FlexEfficiency technology, engineers were able to seamlessly integrate natural gas, wind and solar thermal power. The FlexEfficiency 50 IRCC plant is designed for flexible operation by integrating a next-generation 50 Hz 9FB Gas Turbine, a steam turbine, a generator, 22 MW of GE wind turbines and 50 MW of eSolar concentrated solar thermal tower technology, all integrated by a GE Mark* VIe plant control system.
“When we recently announced our breakthrough FlexEfficiency technology, we talked about being able to better integrate renewables with natural gas to produce cleaner, more affordable and reliable power. This project combines two renewable technologies and natural gas in the same power plant and demonstrates the benefits it can offer to power the future grid. Integrated renewable combined cycle power represents a significant growth opportunity for GE Energy. At MetCap’s site conditions, we will achieve 69 percent plant efficiency, and this technology provides the capability to deliver efficiency greater than 70 percent at Gas Turbine World conditions,” said Paul Browning, president and CEO—thermal products for GE Energy.
“MetCap Energy is on the leading edge of power development and, with this project, they have set a new global standard for the efficient integration of natural gas and renewable energy. This is the first example of how our recent investment in eSolar will enable future growth opportunities for GE Energy, and we already are seeing a growing interest in the industry for this technology. It is another big step forward for GE’s ecomagination initiative and is in lock-step with our commitment to create a cleaner, more affordable energy future,” Browning added.
The power plant will be located in Karaman, Turkey, and will be rated at 530 megawatts at site conditions, which is enough energy to power more than 600,000 homes. It is scheduled to enter commercial operation in 2015. The engineering, procurement and construction (EPC) services will be provided by Gama Power Systems Engineering and Contracting, Inc.
1 In a combined-cycle power plant, greater fuel efficiency is achieved because waste heat is taken from the gas turbine, converted to steam, and then fed to a steam turbine to provide additional energy output. An IRCC plant integrates combined cycle technology with renewable energy resources (wind, solar) to produce additional energy with no increase in emissions.
Page 2 of 3 GE June 7, 2011
Dr. Celal Metin, chairman of MetCap Energy Investments, said: “At MetCap Energy, we believe our projects must simultaneously meet the need for increased energy, environmental responsibility and economic growth, while preserving precious water resources. GE’s FlexEfficiency technology was evaluated versus other state-of-the-art alternatives and was selected because it is best aligned with our vision for the future. In addition to record-setting fuel efficiency, this power plant will have zero liquid discharge, low emissions and a rapid-response, 28-minute start capability. It accomplishes this using an integrated controls system that provides single-button start for all of the elements of the IRCC power plant. And we’ve accomplished all of this with very attractive financial returns for our investment. We think this represents the future of power generation.”
“GAMA is very excited to be involved in this first-of-a-kind integrated renewables combined cycle power plant together with GE. GAMA’s name always has been attached to challenging projects, and we look forward to successfully completing another one where MetCap’s decision to use leading-edge technology will ensure implementing many new innovations such as FlexEfficiency, zero liquid discharge, single button start and many more. We believe this project will set a standard for power generation investments where sunshine and wind is abundant in places like the Middle East,” said Gökhan İnanç, member of the Board of Directors and deputy managing director of Gama Power Systems.
“Since we started speaking with customers about the FlexEfficiency 50 technology last year, there has been great interest in the unique combination of flexibility and efficiency the plant can offer,” said Ricardo Cordoba, president of GE Energy’s Western European Region. “Now in just two short weeks, we have announced our first customer MetCap Energy, here in Europe. This technology breakthrough is being embraced by our customers, and it will transform the industry.”
On June 6, GE announced an investment and licensing agreement with eSolar, a provider of next-generation concentrated solar thermal tower technology. Under the agreement, GE will license and incorporate eSolar technology and software into its IRCC and standalone solar thermal power plants.
“eSolar is proud to participate in this groundbreaking project, integrating our solar thermal tower technology with GE’s wind and FlexEfficiency gas-fired technologies. A significant advantage of solar thermal tower technology versus other renewables is its ability to integrate with thermal power plants and thereby mitigate the challenges of intermittency caused by the weather-related variability of wind and sunshine. This is an exciting new application for us and is clear evidence that our new alliance with GE will generate significant growth potential for our business,” said John Van Scoter, CEO and president of eSolar.
The FlexEfficiency 50 plant is the result of more than $500 million invested by GE in research and development to deliver cleaner, more efficient energy. GE also has announced a $170 million investment in a first-of-its-kind full speed full load test facility in Greenville, S.C., that will provide factory validation of its new technology. In addition to the agreements with MetCap Energy and eSolar, GE has signed a memorandum of understanding with Harbin Electric Co. Ltd. to support the introduction of FlexEfficiency in China. Harbin has been teaming with GE since 2003 to provide heavy duty gas turbines for projects in China.

INNOVATION
The environmental implications are exciting. But finding the right technological balance, while ensuring the viability of these abundant resources, is a challenge that requires innovation.
Leveraging a rich history in gas turbine technology, the revolutionary FlexEfficiency 50 plant delivers industry-leading flexibility that will encourage further penetration of renewables onto grids, as well as enhance the efficient use of fossil fuels.
In support of fluctuations in renewables, fossil fuel prices, and energy demand, fewer plants will be operating in baseload mode. That’s why GE technologies are engineered to deliver enhanced cyclic capabilities that allow utilities to ramp faster and more often, cycle on/off faster and more often, and provide more short-term reserves.
At GE Energy, we understand the significant impact renewable energy sources like wind and solar have had – and will continue to have – on the power generation industry.
The limitless possibilities of flexible operation
FLEXIBIILTY
With the FlexEfficiency 50 plant, operators will have the choice of four unique start-up options that allow them to rapidly respond to electrical industry conditions, limits on air emissions and power demands—all while improving their bottom line. After completion of pre-start conditions, all options are initiated with one-button push-start, enabling automatic plant start-up.

FLEXIBIILTY
Measuring the true costof energy
†Excludes MW-hrs. during minimum turndown ††Includes fuel consumption during start-up
Given today’s shift to more cyclic operation of plant assets, fewer plants are operating in baseload mode. At GE, we believe owners and operators can generate electricity more cost effectively if they include flexibility and efficiency considerations in their evaluation models.
Accounting for both the profitability of power production and the annual fuel consumption for cyclic operation, GE has defined the term FlexEfficiency as:
Profitable annual MW–hrs† Annual fuel consumption††
By evaluating the total annual fuel consumption across a highly variable operating profile, customers will be capturing the fuel costs the way the plant will actually run.
With this metric, and an operating profile that includes 250 starts per year and a mix of baseload, part load and minimum turndown hours, typical advanced combined cycle power plant FlexEfficiency is 54%.
The FlexEfficiency rating for the FlexEfficiency 50 plant is greater than 58% on the same basis including plant part load efficiency greater than 60% down to 87% of the plant baseload power output.
