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.

energy to electricity at a new standard of performance.

Highly efficient and easy to serviceThe W28 550-megawatt generator incorporates hydrogen cooling

of the field and stator core and direct water-cooling of the stator

windings to provide improved cooling capability, as well as

increased reliability and high efficiency. In fact, the overall

generator efficiency exceeds 99% at 0.9 power factor. The use of

water-cooling for the generator stator enables a compact design

that has a smaller generator plant footprint than all hydrogen

cooled generators. Along with its robust construction and an

increased efficiency, the W28 Generator has a tightly sealed stator

frame to prevent gas and oil leakage—helping reduce maintenance

and increase reliability.

The W28 Generator’s one-piece frame construction offers easier

installation; while additional features provide simplified alignment

and improved serviceability. All aspects of the design have been

selected to enhance operability and reduce maintenance

requirements. The W28 Generator and its foundation interface

have been specifically designed to facilitate removal of the

generator from between turbines for maintenance or repair. Its

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.

Operator and Engineers Station

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

monitored, including condition monitors, process control,

historians, maintenance and reliability software, spreadsheets,

and operator logs. Actionable alerts are provided when

abnormalities occur. Enterprise Asset Management (EAM) and

Computerized Maintenance Management Systems (CMMS) are

supported with CIMPLICITY®, MRO Software’s Maximo® EAM

system, the SAP ERP system, and OPC® connectivity with data

sources.

Life Cycle SupportLife cycle support programs are available including self help,

web-based access to resources, such as technical manuals and

drawings, engineering support, remote system diagnostics,

spare-parts ordering, standard and custom training programs,

cyber security and software maintenance programs, and many

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.

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.


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.
