ABENGOA SOLAR The Resource
•
Solar energy comes in two flavors – diffuse and direct (beam)
•
PV can use both components•
CSP can use only the direct because diffuse can not be effectively focused or concentrated
•
So where is the direct solar energy found?

ABENGOA SOLAR Filters to Identify Prime Locations for CSP Development
All Solar Resources
Locations Suitable forDevelopment
Start with direct normal solar resource estimates derived from 10 km satellite data.
Eliminate locations with less than 6.75 kWh/m2/day as these will have a higher cost of electricity. Most of Spain is lower.
Exclude environmentally sensitive lands, major urban areas, and water features.
Remove land areas with greater than 1% (and 3%) average land slope.
Eliminate areas with a minimum contiguous area of less than 1 square kilometers.

and
Benefits
Untapped Electricity Generation Potential–
Solar energy in seven southwestern states –
AZ, CA, CO, NV, NM, TX and UT –
could generate more than 6X current U.S. electricity needs
•
Solar resource for 6,800 GW of versus current nation-wide capacity of approx. 1,000 GW
Significant Population Growth Centers –
15 of the 20 fastest-growing metro areas in the country are in close proximity to solar resource
–
By 2030, an estimated 41 million additional people will move to the Western United States (from 90 million in 2000 to 131 million people)
Environmental Benefits–
15-30 GW by 2030 (up to 37% of West’s power) offsets 15-40 coal plants
–
Compared with coal plants, CSP will save 33-66 million tons CO2

ABENGOA SOLAR
•
Concentrating Solar Technologies can be used to “mine”
this resource.
•
Some of these technologies use curved mirrors to focus the sun’s rays and to make steam, others directly produce electricity.
•
This steam is used to produce electricity via conventional power equipment.
•
In multi-Megawatt plants, CSP provides the lowest cost solar electricity.
•
Can provide bulk and/or distributed generation.

25Solar Power for a Sustainable World
ABENGOA SOLAR Why CSP and Why Now?
•
Necessity –
the utilities’
other options (coal, nuclear or NG) have significant long term risks with cost implications
•
Uniqueness
of thermal energy storage•
Favorable but still unreliable policies,
such as the RPS and the ITC (both of which are essential) in the US and Feed-in tariffs elsewhere
•
Public opinion
favors solar
26Solar Power for a Sustainable World
ABENGOA SOLAR Awareness of CSP
•
Utilities
–
Growing fast where good DNI and policies exist
•
Policy makers
–
Generally lagging as evidenced by inadequate or unreliable policies at all levels of government
•
Investors
–
Growing fast as evidenced by news articles and conferences but lagging wind and PV investments, held back by policy uncertainty and today’s financial market situation
27Solar Power for a Sustainable World
ABENGOA SOLAR Attributes of CSP in the Eyes of Utilities
•
Utilities are familiar with steam
generation•
Suitability for utility scale
installations of
100MW or more•
Stable, known and decreasing costs and zero carbon emissions provide hedge
against NG
price volatility and carbon caps•
Other generation options have significant risks
•
Ability to provide firm dispatchable output which is of great value
to utilities
28Solar Power for a Sustainable World
ABENGOA SOLAR TES
•
Thermal energy storage allows the electric energy to be shifted for use then it is needed more.
•
TES allows solar electricity to be generated to met utility peak demands or to allow solar to become a base-load power source
•
TES is the cheapest and most efficient form of storage for electric generation
•
However the current indirect two-tank is too expensive to meet long-term cost goals
•
A promising approach is to use molten salt in both the solar field and for storage, but it has risks that appears to be manageable

ABENGOA SOLAR The Cost of CSP
•
There are many costs and they are must be carefully defined –
capital cost, energy cost as
nominal, real, constant dollars, first year, levelized and average
•
Cost is not a wish or a hope -
it depends on many variables, all of which must be known (the EPC contractor and the investors must know what it is)
•
Costs change and that risk must be managed•
The market will find the cost and the value of CSP
•
Will illustrate the impact of financial parameters, plant size, market size and incentives on the cost of energy from CSP plants

ABENGOA SOLAR CSP Costs Today and Tomorrow
•
In the SW US, with best conditions, LCOE is in the mid-
high teens in ¢/kWh for firm dispatchable power and could drop to the low-mid teens with existing incentives, assuming commodity prices do not rise further and financial markets do not get weaker.
•
Current cost gap is 2 -
5 ¢/kWh
•
Several independent and credible studies project 8 ¢/kWh (nominal) after 4GW installed, removing the cost gap and becoming competitive with natural gas

ABENGOA SOLARCSP Competitive with
Base Load
•
Previous slide shows that the switch to molten salt would allow trough power to compete directly with low carbon power.
•
Scale up to larger power parks and learning could allow troughs to compete directly with conventional base load in the future
69Solar Power for a Sustainable World
ABENGOA SOLAR Future for CSP
•
Cost and efficiency losses require further R&D•
An R&D path has been identified such that future CSP with low-cost storage could be as competitive for base load power (high CF) as conventional pulverized coal fired plants.
•
Given the escalation in fuel costs, this 2007 scenario could be even more likely today
•
Assuming carbon constraints (cap and trade, sequestration, etc.) CSP would be even more competitive
70Solar Power for a Sustainable World
ABENGOA SOLAR Ability to Scale Up
•
Key components are generally available -
steel, glass, concrete, copper, molten salt and turbines
•
Major companies –
6 trough + 4 tower•
Assume each builds 2 GW by 2015 for 20 GW total
•
Assume 5-10GW per year thereafter to reach 95- 170 GW by 2030 (DOE projects 15-20 GW)
•
This will need capital at about $5B/GW, 10 square miles/GW hence several national CSP zones with new transmission
71Solar Power for a Sustainable World
ABENGOA SOLAR What’s in the Way?
•
Policies –
Congress finally extended the ITC but there is no
“I”
there now
•
Cost
–
“Relatively”
high cost of electricity but gap is
closing fast•
Transmission
–
Inadequate or not available, slow and costly
to build and the queue system is broken in many locations•
Land
–
Need access to good sites and each ownership type
has its own challenges•
Permitting -
Slow and costly
•
Environmental
–
Growing concern in some places over
access to the desert regions needed for CSP
72Solar Power for a Sustainable World
ABENGOA SOLAR Other Needed Policies
•
“Good”
carbon policies•
Feed-in Tariffs at state level deserve consideration
•
Land access policies •
Transmission policies
•
Exclusion of property and sales taxes

are coming –
will partially or totally close the cost gap•
CSP can scale up
fast
without critical bottleneck materials (we hope) making it a good response option
• Price for CSP power is in commercial range and costs will come down
with increased capacity and will fall below natural gas in the next few years
•
Many technologies options
add certainty
to cost reduction projections •
US and EU R&D programs
will continue to grow in size and value•
Economic development and environmental benefits
will drive political support
•
The CSP market
in the SW US can grow to 20 GW by 2015 and between 95 and 170 GW by 2030 and a comparable rate in the rest of the world.
