– Future investment required to secure the cash flows at time t (called “X”).
– Levelised cost of electricity for when the wholesale electricity price gives a zero NPV, or (S‐X)=0.
– Uses a Monte Carlo Method for the probabilistic NPV Option Value calculations based the on NPV probability distribution (S‐X).

Illustration of Option Value from NPV probability distributions:
Termed “Net Present Option Value - NPOV” in this study
Difference between LCOE and NPV Option Value:
LCOE Net Present Option Value (NPOV)p ( )
Parameters are deterministic. Parameters are probabilistic.
LCOE is the electricity price when the NPV is zero.
NPOV is the upside in the NPV probability distribution where NPV is greater than zero.
NPOV is the upside in NPV at the investment date, discounted at the firm’s cost of capital.
LCOEs for different technologies are compared relative to a constant electricity price
Different technologies are compared in terms of NPV, NPOV magnitude, and “volatility” in the NPV distribution.
electricity price.
In this study of LCOE, there is constant electricity price and CO2 price for the life of the facility.
Electricity and CO2 prices, in this work, follow an upward trajectory for the life of the facility, with volatility.
NPOV gives an indication of how much expenditure could be made now to enable the option for commercial investment in the future, given specified learning curves for the technologies and future price scenariosscenarios.
Probabilistic Calculations for NPOV
• A simulation method that computes thousands of cases of future investment payback for a given case has been used.
• Each trial was randomly selected from the input probability distributions of the variables involved, both “S” and “X”.
• The option condition (e.g. don’t invest for S<X) was handled by examination of the output variable distributions.
• In the ATSE project, we have checked this method against the analytical methods for some simple analytical option calculations, with agreement.
• Judgment has been used to determine the nature of the input data probability distributions.

Wholesale electricity prices are related to the CO2 price according to the Treasury/Garnaut model results in the ATSE study

Key Findings ‐ 1
Th lt d t t th t th fi i l i bilit f l b l t i it– The results demonstrate that the financial viability of new low‐carbon electricity generating technologies will require that electricity prices rise substantially over time, unless they are subsidised.
– NPOV gives additional insights into the rankings of the attractiveness ofNPOV gives additional insights into the rankings of the attractiveness of alternative power generation technologies:
and the financial sensitivities to many of the business parameters associated with their deployment.
– The results show that with increasing prices for electricity and carbon emissions, a portfolio of low‐carbon technologies can be economically deployed over time, for example:
h d l f i d d ffi i bi h l i short term deployment of wind and efficient gas turbine technologies
longer term development of solar thermal, geothermal and carbon capture and storage technologies for both gas and coal
in purely financial terms nuclear energy technology provides a in purely financial terms, nuclear energy technology provides a competitive medium term option
Key Findings ‐ 2
– NPOV results indicate that an investment of some $10 billion (in today’s dollars) in the period between now and 2030 to 2040 is justified in support of alternative technologies now through expenditure on RD&D, pp g g p ,infrastructure, regulatory regimes, exploration, and the like:
but further work is required to fully validate this estimate.
– The methodologies adopted in this study should find application in theThe methodologies adopted in this study should find application in the analysis of other new technologies, for example:
IDGCC for brown coal, ocean‐ and tidal‐derived energy, distributed energy generationenergy generation
Transmission costs for new technologies in remote locations
Projects aimed at energy efficiency improvement
f d l h h b f d Infrastructure developments, such as hubs for CO2 mitigation and sequestration.
Limitations of the Analysis
– The results from the study are for individual technologies considered in isolation:
A “highest NPV” generating fleet portfolio analysis would require supply and demand scenarios and additional cost analysis (e.g. for energy transmission).
– Wholesale electricity price in the future will be driven by the selected portfolio of new technologies, which will in turn be driven by the imposed CO2 price trajectory.
– In this study, the investment returns have been predicated on increasing electricity and CO2 prices and no consideration has been given to alternative policy choices:
For example, mandating or regulating various technology options or resource use.

Legal and regulatory considerations
• Property rights for transport including between countries
• Conflicts with resource exploration and developmentEnvironmental risk (approvals long• Environmental risk (approvals, long term monitoring, remediation)

Public Acceptance Issues
• Is reducing CO2 emissions a priority compared to other social / environmental issues?other social / environmental issues?
• CCS just a clever ploy of fossil fuels industry
I fl f ti i t i it• Influence of activist minority
• Not under my backyard (NUMBY)
• Getting the regulations right / Clarity on liability
• Demonstrating that it works

SUMMARYCO2CRC t h i l lt i i il l ti iti• CO2CRC techno-economic analyses result in similar relativities as
ABARE/EPRI and Low Carbon Energy Report (LCER)
• Interesting difference is potential benefits of retrofit vs new build
• LCER considers only power plants; what might the impact be on industries (cement, steel, gas processing)?
C f f f f CCS• Cost of new electricity from fossil fuels with CCS comparable to alternatives (nuclear, geothermal, biomass)
• Cost of specific CCS project depends on:p p j p– which capture technology– location, depth, geological quality of storage site
regulatory / liability framework– regulatory / liability framework– social / public acceptance (“show-stopper”)
