How does PVsell calculate Block Tariffs?

PVsell performs annual financial calculation accounting for export, peak demand, tariffs that vary with time/consumption, and changes in tariffs.

The Block Tariff is a type of tariff structure where the price of electricity varies depending on how much electricity is consumed in a given period.

Block Bills are charged in "blocks" of use, that is, a customer pays a different amount for the first portion or "block" of energy to what they pay for subsequent blocks of energy (e.g., one rate for the first 10 kWh and a different rate for usage above this threshold). The tariff rate therefore depends upon how much the customer consumes.

1. The Quantity of Energy & Energy Rate/Charge values

For Block tariffs, you enter:

1. the quantity of energy consumed in the 1st block
2. and the energy rate (faster option), or the dollars charged (detailed method, PVsell will work out the energy tariff for you) in the 1st block

Then you repeat this for subsequent blocks, and enter the block period.

The Quantity input is important as it specifies when PVsell will start applying the next tariff.

2. Standing Charges

Separately, enter any controlled load charge. Solar won't address this portion of the bill as it is on a separate circuit, but entering complete information helps PVsell to perform accurate calculations that match your customer's bill as closely as possible.

Specify other bill information:

• How do I specify electricity price rises (and what electricity price rises do you recommend)?
• How do I enter a feed-in tariff?
