Title: Tradeoff Analysis
1Trade-off Analysis
- Basic questions
- Are the solutions that are being suggested as
good as possible, i.e., are they on the
frontier? - How much must I give up to get a little more of
what I want most? - Pareto Optimality

Pareto Superior Alternatives
Attribute 2
3Trade-off Analysis Attributes
- Quantifiable characteristics of the problem
- How could / would we define a bad / worse good
/ better outcome? - Reduced cost of service
- Improved reliability in delivery
- Reduced air emission
- Less use of land
- No use of Chlorine in the production process
4Trade-off Analysis Uncertainties
- Events over which the analyst has no control
- it might but then again
- International economic conditions
- International oil prices
- Regulatory change
- Resource ( land human skills ) Availability
5Trade-off Analysis Options
- Actions that could / can be taken
- We can build / buy / legislate / regulate
- Build a new power plant
- Invest in energy conservation / demand side
management - Purchase scrubbers for old power plants
- Close the power plants and build new clean plants
- Move all power generation off shore
6Trade-off Analysis Scenarios
- Combining the options into a set of rational
plans that can be analyzed - What could / can actually be done given reality
and resource constraints? - Give growth in demand (and uncertainty)
- Close the dirtiest power plant, added one new,
clean unit and invest 100 million in demand side
management. - Invest in scrubbers for all old plants and build
one new, high efficiency, clean power plant (no
DSM)
7Trade-Off Analysis Example
500 million for DSM
Build 2 new nuclear plants
300 million for DSM and 1 new power plant
Cost / kWh
Scrubbers on all old units
100 million for DSM close 1 plant, Scrubbers on
all others
No DSM Close 2 Build 1 Scrubbers on units
operating gt 35 of the time.
Tonnes of Sox Emissions
8Trade-Off Analysis Example 2
500 million for DSM
Scrubbers on all old units
Build 2 new nuclear plants
Cost / kWh
300 million for DSM and 1 new power plant
No DSM Close 2 Build 1 Scrubbers on units
operating gt 35 of the time.
100 million for DSM close 1 plant, Scrubbers on
all others
Tonnes of Nox Emissions
9Trade-Off Analysis Example of Uncertainty
Increased International Oil Prices
Cost / kWh
Tonnes of Sox Emissions

11Policy Analysis Truths
- Question / challenge the assumptions
- THE forecast is always wrong
- Communication is the key Make it more
understandable not more complicated - Measure the important variables not the variables
that are easy to measure
