8. The future of CSP:
Cost is not the whole story
Historically, solar, like other
renewable energy sources, has
faced two challenges: costs
and dependability
Costs continue to drop, but
they are only part of the story
Solar energy providers must
address dependability—

regardless of weather
conditions or time of day
CSP technology providers must
meet customers’ reliability needs

Direct solar steam Solar steam generators can also
generator/fossil-fired hybrid be integrated into existing energy

If the sun is not available, fossil augment power production and
fuel picks up the load at a fraction lower emissions
of the cost of building a
standalone backup plant

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 evaluated

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.
