Hello Paul,
I am implementing SAM as simulating tool in my company. We have spoken by email about some basic issues, but this one may be useful for other people.
Inside financial models, I am trying to intruduce the inputs for an spanish bill. Everything is ok except the rates for demand charges. We have different ways to calculate these charges, for example there is a "3.0A bill" which demands charges are defined as follows:
- If max power is between 85% and 105% of hired power, the charges are applied into the max power (in a month).
- If max power is lower than 85% of hired power, the charges are applied into the 85 % of hired power.
- If max power is higher than 105% of hired power, the charges are applied into Pf = Pr + 2·(Pr - 1,05·Pc). Being Pr the max power and Pc the hired power.
In the following web there is a better explain, but in spanish:

Do you figure out how to implement it into the simulation parameters of Demand Charges? Or do you have any spanish simulation which you can sare?
If someone has solved it, any help will be grateful.
Best regards!
