How to enter different TARIFF rates for WIND in Electricity Rates Sheet in SAM

Hello, I am Hamza. I have a query to ask.  
I am doing economical analysis of wind farm.
And I am confused that "How to enter different TARIFF rates for WIND in Electricity Rates Work Sheet".
For example I have Two Tariff for 25 years. Tarif A is for Year 1 to Year 10. Tarif B is for Year 11 to Year 25.
How how I set the PERIOD, TIER, TARIF, MAX USAGE etc. 

Kindly let me know. 

Thanks in advance.

Hi Hamza,

It is not possible to enter rates that change after a certain number of years. The rates on the Electricity Rates input page for the Commercial, Residential, and Third Party Host / Developer financial models are for Year 1.

I created a feature request here: github.com/NREL/SAM/issues/1083

Best regards,
Paul.
