22Solar Power for a Sustainable World
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
•
Concentrating Solar Technologies can be used to “mine”
this resource. They were covered by
the previous speaker.•
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.
How do we develop this resource?

88Solar 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
•
Uniqueness
of thermal energy storage•
Public opinion
favors solar
•
Favorable but still unreliable policies, such as the RPS and the ITC (both of which are essential)

99Solar 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 the federal and state levels
•
Investors
–
Growing fast as evidenced by news articles and conferences but lagging wind and PV investments, held back by ITC uncertainty and today’s financial market situation

1010Solar 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

1717Solar Power for a Sustainable World
ABENGOA SOLAR Attributes of CSP in the eyes of investors
•
Scalable•
With a good Power Purchase Agreement, the return on investment can be adequate to encourage main-stream
equity and
favorable debt financing terms.•
Once debt is paid, operates with no fuel –
has potential of becoming a “clean cash cow”.

1818Solar Power for a Sustainable World
ABENGOA SOLAR Today’s CSP Market
•
Over 400 MW in reliable operation, most for about 20 years
•
Over 4,800 MW under contract•
Those 4,800 MW will bring about $20 billion in investments and create over 26,000 jobs
•
That will not happen unless the Federal ITC is extended for eight years. SB 3335 must pass this week.

1919Solar Power for a Sustainable World
ABENGOA SOLAR What’s in the Way?
•
US Congress
–
Seems unable to do the right thing regarding extending the 30% ITC for 8 more years.
•
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
•
Land
–
Need access to good sites and each ownership type has its own challenges
•
Permitting -
Slow and costly•
Environmental
–
Growing concern over access to
the desert regions needed for CSP

2424Solar Power for a Sustainable World
ABENGOA SOLAR Forecast
•
Carbon limits
are coming –
will partially or totally close the
cost gap•
CSP can scale up fast
without critical bottleneck materials
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 •
DOE’s
CSP R&D program will continue to grow in size and
value•
Economic development and environmental benefits will drive state support
•
In a very few years, the CSP market in the SW US can grow to 2-4 GW per year

2525Solar Power for a Sustainable World
ABENGOA SOLAR Conclusions
•
CSP is a Unique Renewable Technology–
Large resource
–
Ability to store energy to fit utility need
–
Near-term potential for cost competitiveness
•
The Market is Rapidly Developing–
Utilities interest in CSP is growing
–
Large credible, financially stable developers
–
Real (financiable, buildable and reliable) projects
•
Policy Decisions will Maintain Momentum or Kill CSP–
Long term ITC extension -
if not extended this option
will not happen–
Supporting state policies

2626Solar Power for a Sustainable World
ABENGOA SOLARThe answers to the two
questions
•
What is CSP?–
CSP is proven and operating utility scale solar that has the potential to power the SW and, with new transmission, much of the rest of the US
•
Why should Congress care?–
Has the potential to quickly provide very large amounts of clean energy at prices lower than fossil based generation
–
Creates non-outsourcable
jobs, stimulates local
economies, provides firm dispatchable power and reduces carbon emissions
