Technical Description
• TEC will manufacture pipeline quality SNG to be used to fuel a conventional 2x1 “F” Class power block
• Power production (after CO2 compression) is expected to be 730 MW gross when both gas turbines are operating and 405730 MW gross when both gas turbines are operating and 405 MW gross when one gas turbine is operating

M j Diff IGCC d H b id IGCCMajor Differences: IGCC and Hybrid IGCCThe following are major design differences between conventional IGCC and Hybrid IGCC configurations:
• An IGCC configuration typically involves air side integration between the air separation unit and the combustion turbine (“CT”). This integration is eliminated in the TEC Hybrid IGCC design
• The nitrogen (N2) integration between the air separation unit and the CT for emission control purposes is eliminated since low-NOx burners can be used on CTs that burn natural gas
• TEC employs a quench gasification design that has more operating hours experience than the radiant designs suggested for some IGCC plants
• The CTs in the TEC design will burn pipeline quality SNG (methane), while conventional IGCC projects burn synthesis gas (carbon monoxide and hydrogen (H2))burn synthesis gas (carbon monoxide and hydrogen (H2))
• The TEC design allows the power block to be efficiently operated independently even if the gasification and / or SNG islands are shut down for maintenance
– In the case of conventional IGCC, the power block can still be operated on natural gas, but because the CTs are designed to burn syngas, the efficiency is significantly reducedg y g , y g y
• Simplification of design leads to a higher expected facility availability

St St t d L l S t• The Illinois Clean Coal Portfolio Standard Law
(“ICCPSL”), also known as SB1987, was signed into law in January 2009
• “…[the legislation that supports TEC] provides a unique opportunity for Illinois to become the national leader in the effort to build the kind of
Strong State and Local Support
signed into law in January 2009
• Creates a framework for developing coal gasification projects with CO2 capture and storage, requiring emissions from these electric generation facilities to be as clean as
national leader in the effort to build the kind of green economy championed by [President] Obama.” Lisa Madigan, Illinois Attorney General
• “Construction of the [TEC] will be an economic catalyst to kick-start our economy, creating good-g
natural gas generators
• Requires electric utilities and other electric retail suppliers in Illinois to purchase 100% of the electric output from clean coal facilities

catalyst to kick start our economy, creating goodpaying jobs that help bolster working families.” Michael Carrigan, Illinois AFL-CIO President
• “[TEC] is a perfect example of a project that uses coal in an environmentally responsible manner. We
under 30 year Sourcing Agreements. Contracting with these electricity providers provides a built-in customer base for the plant
• Law allows Tenaska to pass through its operating costs and recover capital costs
urge others to support this project." Angela Tin, Director of environmental programs for American Lung Association of Illinois
• “Coal gasification plants like the TEC are a win-win-win for Illinois They are good for economicoperating costs and recover capital costs
using hypothetical capital structure (55% debt / 45% equity) and a return on equity (“ROE”) of up to 11.5%. Similar to other cost-of-service rate base frameworks
win for Illinois. They are good for economic development and good for the environment. And if financed correctly with cost-based rates, they are a good deal for consumers too.” David Kolata, Executive Director, Citizens Utility Board

Illi i Edit i l S t• “We hope that a deal can be worked out that would allow Illinois, and the nation, to reap the benefits of
building a clean coal plant in Taylorville at a reasonable cost to consumers… Illinois has much to gain as the center of clean coal. The Taylorville plant would produce enough power to serve hundreds of

as the center of clean coal. The Taylorville plant would produce enough power to serve hundreds of thousands of homes. The gains in clean air also would be significant.” Chicago Tribune, Editorial: “Don’t forget Taylorville”, Feb. 1, 2008
• “The St. Louis region's future and that of the nation rest on two seemingly contradictory challenges: our growing appetite for energy and the pressing need to slash emissions of heat-trapping greenhouse g g pp gy p g pp g ggases that are released when we produce it. It's a Gordian knot of a problem, but Illinois is poised to lead the country toward at least a partial solution – if the General Assembly in Springfield is smart enough to recognize the opportunity…
…Whatever other political dramas are unfolding in Springfield, legislators need to get this work [SB 1987] done right away… Once gasification technology has proved itself, IGCC plants eventually could produce power while producing few pollutants and capturing and storing up to 90 percent of the carbon dioxide. That's a solution we all could live with.” St. Louis Post-Dispatch, Editorial: “The future, now”, July 19, 2007

Mandatory Purchase Obligation
ILLINOIS CLEAN COAL PORTFOLIO STANDARD LAW
• Requires Illinois electric utilities and Alternative Retail Electric Suppliers (“ARES”) to enter into 30 year Sourcing Agreements to collectively buy 100% of the electric power output from the “Initial Clean Coal Facility”
• The amount of power each of the utilities and ARES purchases will be based on their respective share of the Illinois retail electric market
FERC Role
• Sourcing Agreements are wholesale contracts subject to exclusive FERC jurisdiction
• Form of Sourcing Agreement will be filed as a tariff
• Cost-of-service treatment is a well accepted FERC standard for “just and reasonable” rates

ICCPSLCost Recovery
ICCPSL
• Legislation allows TEC to pass through all operating costs on a monthly basis
• Allows TEC to recover capital costs using a capital structure of 55% debt / 45% equity and an ROE of up to 11.5% (to be determined by FERC and approved by the Illi i G l A bl i t fi i l l )Illinois General Assembly prior to financial close)
Requirements
• Provides that the initial clean coal facility must: (1) capture and sequester at leastProvides that the initial clean coal facility must: (1) capture and sequester at least 50% of the CO2 either (i) in an EOR application or (ii) geologically or (2) buy annually up to $15 million in carbon offsets (with the cost of such offsets not being passed through in rates)
• Illinois General Assembly to approve TEC after receipt of final Facility Cost Report
