Where the batteries sit

Colored columns are the 93 with matched merchant revenue; height is capacity (NQC where filed, else nameplate), and color shows exact yield for the top 20 and yield bands for the rest on a fixed $0 to $12/kW-mo scale. Grey dots are other operating plants we can place with no matched merchant revenue in FERC EQR, shown for fleet context, not ranked. IOU territories are tinted. Drag to pan, ctrl-drag to tilt and rotate, scroll to zoom. Click anywhere to drop a pin and find every battery within 100 km.

Revenue by IOU territory and owner

Tile area estimates merchant revenue from the public yield value × project MW × 12,000; yield values beyond the top 20 use band representatives. Color uses a fixed $0 to $12/kW-mo yield scale. Group by IOU territory or by owner, the entity that files the revenue in FERC EQR. Positive-revenue sites only. Click a tile to zoom in, the top bar zooms back out.

Counts of sited projects in each public $/kW-mo yield band, grouped by IOU territory.

How the fleet charges and discharges

CAISO's daily storage report, the whole fleet's real-time dispatch. Each column is a day since January, each row a time of day. Coral is charging through the midday solar trough; blue is discharging into the evening peak. System aggregate, preliminary, not settlement quality, not per-resource.

How full the fleet runs

State of charge across the same window, GWh stored. The fleet fills through midday charging and drains across the evening peak, the storage side of the arbitrage the heatmap above shows.

$/kW-mo is FERC EQR merchant revenue per kW of canonical capacity per month, summed over the trailing four quarters 2025-04-01 to 2026-03-31 and divided by twelve. An asterisk marks one or more quarters missing from the matched filings; the divisor remains twelve. Merchant is the energy and ancillary revenue sold to CAISO, about a third to a half of a battery total, it excludes resource adequacy capacity payments. Covers 93 nodes that disclosed positive merchant revenue, sized by NQC where filed and EIA nameplate otherwise. The map also shows 190 operating plants with no matched EQR node as grey location dots, shown for fleet context but not ranked. Locations are crosswalked to EIA plants and graded against satellite imagery, not a settlement statement.

Capacity uses NQC where filed and EIA nameplate otherwise. The fleet average includes all operating capacity; the median and ranking cover nodes with matched revenue.

Numbers are estimates for benchmarking, not settlement statements. Full method: how we compute CAISO BESS revenue.
