BESS

Fixed-revenue scenarios (CRCAP)

What annual Fixed Revenue (RF) does a BESS need in LRCAP 2026 to earn the real return you choose? Model in real terms (RF is IPCA-indexed), 15 years, 4 h. Fields marked assumption are our choices, not cited figures — edit them.

Looking for home / distributed generation storage? We don't model residential MMGD yet — for rooftop solar, see SimSolar.

Submarket assumption

Inherited by the pre-feasibility draft. For real geography (busbar, TUST, β), pick a site under Siting (in Portuguese).

Capex scenario (cited)

Low: global benchmark (FT via ABSAE) · central: ABSAE/Newcharge 2025 · high: EPE parameter Aug/2024. Sources in the methodology.

TUST/TUSD at zero: enter the network cost for your busbar (ANEEL confirmed charges on both ends — load and injection). Automatic per-busbar wiring arrives in Phase 2.

Against the only public RF benchmark

New thermal, product 2028, 2nd LRCAP (Mar/2026): R$ 2,46 mi/MW·ano. Your required RF sits 67% below the benchmark; if the battery auction cleared at that level, the implied real IRR of your scenario would be 43,4% a.a.. Different product (thermal ≠ 4 h battery) — order of magnitude, not a bid reference. The auction price cap comes in the ANEEL tender.
