LRCAP — capacity reserve auction · large batteries (≥30 MW) selling capacity to the grid; fixed revenue per MW — not residential storage
Where is a battery worth it in Brazil?
Screening and pre-feasibility for battery storage (BESS) for LRCAP 2026 – Storage, the battery auctions on 02 and 04 Dec 2026. Fixed-revenue scenarios with open, editable assumptions — every figure cited or marked as an assumption, never a forecast.
Looking for home / distributed generation storage? We don't model residential storage yet — for rooftop solar, see SimSolar.

PLD (Brazil's spot price) context by submarket
Average daily spread between the 4 most expensive and 4 cheapest hours (the window of a 4 h BESS) — CCEE history, no forecasts. Under the auction regime, energy settles at PLD under ONS dispatch; this context sizes that exposure.
Dataset cut: hourly PLD 01/01/2021 → 10/07/2026 (CCEE via spotcast).
| Submarket | Avg. spread 2024 | Avg. spread 2025 | Avg. spread 2026 (cut 10/07 · next window 24/07) | P90 2026 |
|---|---|---|---|---|
| SECO Sudeste/Centro-Oeste | R$ 46/MWh | R$ 142/MWh | R$ 252/MWh | R$ 475/MWh |
| S Sul | R$ 46/MWh | R$ 136/MWh | R$ 168/MWh | R$ 330/MWh |
| NE Nordeste | R$ 66/MWh | R$ 127/MWh | R$ 212/MWh | R$ 421/MWh |
| N Norte | R$ 49/MWh | R$ 116/MWh | R$ 210/MWh | R$ 421/MWh |

Frequently asked questions
- What period of hourly spot-price data is available for analyzing batteries in Brazil?
- The series covers 1/1/2021 through 7/10/2026. It uses CCEE hourly PLD history to compare price spreads and arbitrage scenarios, without forecasting future prices.
- What was the average daily price spread for battery arbitrage in Brazil's electricity submarkets in 2026?
- The average spreads in 2026 were N: BRL 210/MWh, NE: BRL 212/MWh, S: BRL 168/MWh, SECO: BRL 252/MWh. Each value compares the daily average of the four most expensive hours with the four least expensive hours.
- How many daily submarket observations are included in the historical PLD spread analysis?
- The analysis includes 8,068 daily submarket observations across the available period. Each observation is calculated from that day's hourly prices for one submarket.
- Which Brazilian electricity submarkets are compared for battery price arbitrage?
- The analysis compares 4 submarkets: N, NE, S, SECO. For each one, it shows the average daily spread and the 90th percentile for the latest available year, 2026.
