Benefits of an Excel model The Excel model –Uses current Excel technology –Can be understood and updated by anyone with Excel knowledge –Can be instantly updated for many changes
3
How does the model work? How does data get into the model How do the allocators work How does it specifically assign How does the allocator exhibit page work How do we print the reports
4
What happens in the model?
5
Tabs These are the tabs in the model We’ll discuss each tab in the following slides

How do we get the new data into the model? There’s input data on 3 tabs of the model, Input1, Input2 and AllocatorData Input1 is for total company numbers and assigning the allocator to use Input2 is for allocators and direct assignments AllocatorData is the raw demand that gets used to develop the demand allocators

How do we get reports out of the model? How do we print the exhibit pages How do we print the workpapers How do we print just the summary pages How do we get those same reports for the production and distribution tabs

How do we change the model? Inserting/Removing rates Inserting/Removing detail Adding/Changing allocators
17
Differences between DTE & CE Models Assignment of the production allocator AllocatorData Tab –Raw Demand Data –Classpeak & 4CP MH
18
Choosing the Production Allocator Here you enter either 4 or 12 for the ‘method’ variable and then enter the weightings for demand, energy on peak and total energy This is a little different than the DTE model in that you do not need to enter anything for the ‘Staff’ variable (located in B3)
19
Raw Demand Data The AllocatorData tab includes the raw demand data for 12 monthly peaks as well as the 4CP MH and classpeak Here you can see the 12CP data
20
How to change 12CP into any other monthly peak method All you need to do is delete the raw data for the months not in use For example, if you wanted to make a 4CP allocator you would delete the data from months circled below
21
Creating a 4CP Allocator Now that the off months have no data, the totals update and those values are used to create the 12CP allocator The name of the allocator does not change, but the underlying data has The assignment of the production allocator needs to use 12 for the ‘method’ variable
