4.2 Creating Policy Scenarios
Go to the Manage Scenarios screen
(shown right) and create the
following five scenarios:
• Efficient Lighting
• Efficient Refrigerators
• CNG Buses
• Hybrid cars
• Natural Gas & Renewables
• Industrial Efficiency
The Manage Scenarios screen
should look like the one shown right.
Make sure each of the new policy scenarios is created beneath the Reference scenario. In
this way the scenarios will inherit the expressions already entered for the Reference scenario.
Finally, create a Mitigation scenario under the Reference scenario that is a combination of
the five policy scenarios listed above. Use the Inheritance tab to set that this scenario also
inherits its expressions from these five policy scenarios.
4.3 Entering Costing Data
Next you will enter the data that that will be used to evaluate how these scenarios differ from
the Reference scenario.
In general, the unit costs of different technologies are the same for different scenarios, but the
scenarios will differ in terms of how much of each technology is implemented or how much
of each fuel is consumed. Thus, you first need to enter cost data in the Current Accounts
scenario. After that you will enter data describing the penetration of the technology in the
different policy scenarios.
We will start by specifying cost data for demand-side options. In general we need to enter
three types of data describing:
• Technology Penetration: how many of the new (efficient) types of devices will be
installed in the Policy scenario?
• Technology Performance: how efficient are the new devices?
• Technology cost: how much do the new devices cost? We can either specify the total
costs of competing devices used in the Reference and Policy scenarios or we can
simply enter the incremental cost of the new devices introduced in the Policy
scenarios relative to the costs of the device used in the Reference scenario.
