Where does a power plant's money go?
The full cost stack — CAPEX and recurring — in R$/Wp and % of total. Pre-filled with a typical project; adjust plant size and assumptions. When a figure is Brazil-specific, that shows on the label. Every number is cited or an assumption (editable).

In the Brazil dataset, TUST/TUSD (transmission/distribution tariffs) is often the largest recurring cost after O&M (≈56% of the charges line, EPE). The value here is an assumption tied to the Brazilian context until you pick a connection busbar; integration with real busbar tariffs (tust product) and the incentivized-source discount come in a later step.
How to read these figures
- CAPEX in R$/Wp is DC-side (module peak); EPE quotes R$/kW at AC capacity (inverters). Conversion uses the DC/AC ratio (1,30), editable.
- Every EPE (Brazil) figure is in December 2022 reais; adjust by IPCA/FX for the target year.
- The sub-split inside “equipment” (modules/inverters/structure/BOS) is an assumption; totals and the connection share (~10%) are cited (EPE).
