  21. 21. Eligibility for ITC/MACRS and Property Tax Reduction ITC and MACRS 1. Solar Energy Equipment - Used solely to generate solar-based energy • ITC and MACRS apply in full to all solar energy components. 2. Dual-Use Equipment - Used to generate both solar- and gas-based energy • For solar fractions below 75%, ITC and MACRS do not apply to dual-use equipment • For solar fractions above 75%, ITC and MACRS apply in a pro-rata manner (e.g. if annual energy output is 85% solar and 15% gas, ITC and MACRS apply to 85% of the dual-use equipment; if annual energy output is 65% solar and 35% gas, ITC and MACRS do not apply) 3. Auxiliary Equipment - Used solely to generate gas-based energy • ITC and MACRS do not apply to auxiliary equipment. Property Tax Reduction 1. California - Adding a gas boiler reduces the tax exclusion on the dual use equipment to 75% of its full cash value 2. Other States – currently being evaluatedAREVA SOLARCSP – J.

  26. 26. Solar steam augmentation for coal-fired power plant The solar augmentation concept for coal-fired For older, lower-pressure subcritical coal-fired power plants is simple. plants, an alternative integration scheme is to AREVA’s solar system uses reliable, land-efficient supply high-pressure saturated steam from the SSGs to replace extraction steam used for solar field to the boiler’s evaporator outlet or drum. feedwater heating. This alternative offers potentially larger fuel savings The steam that is not extracted can continue to by displacing greater amounts of fossil steam with expand through the steam turbine to produce more solar steam than in the bypassed feedwater heater electricity without increasing plant emissions. case.AREVA SOLARCSP – J.

  27. 27. Solar steam augmentation for gas-fired power plant (HP booster) Existing gas-fired, combined-cycle power plants can readily mix AREVA’s solar-generated steam with the power plant’s intermediate pressure (IP) evaporator or cold reheat steam. The solar steam enables the turbine to produce additional electricity without additional fuel.AREVA SOLARCSP – J. Goyal/ February 2011 - p.27
