On a day with negative prices (the middle chunk), interesting to see the inverter set an export limit and curtail that rooftop solar.
System balancing benefit of exposing consumers to hourly price shape.

ERCOT's Texas Energy Fund will land at 5.5 to 7 GW, well short of the 10 GW target. Gas CapEx has doubled since 2023. Two Frame CT peakers are online. Turbine delivery delays mean solar and battery will still dominate capacity additions through the 2030s.

NEM battery revenues could fall 3.6% across 2026-27 under El Niño conditions, but the seasonal split matters more than the aggregate. Winter compression runs 9% NEM-wide, hitting Victoria hardest at 30%. Summer swings on heatwave frequency, not rainfall alone.

WEM battery revenues hit $40k/MW/year in May, up 43% month-on-month as daily spreads widened to $97/MWh. But merchant returns stayed negative for a second month. Energy revenue fell to minus $12k/MW/year. RCM payments alone kept the fleet profitable.

NECEC's real-time premium in Maine ($24/MW-day) only appears on days the line swings >300 MW. On steady-operation days (most days), the premium drops to $39/MWh spring, $10/MWh winter. The edge tracks line reliability, not import volume.

PJM's Real-Time TB4 spreads ran $389/MW-day in May, up 106% year-over-year. Three heat-driven days accounted for most of that surge. A second spike at month-end came from a storm ramp, not heat. Volatility concentrated in the Mid-Atlantic.

ERCOT battery revenues fell to $1.88/kW-month in March, 23% below the 12-month average. Real-Time Energy prices peaked at just $219/MWh in May. Calm weather and continued fleet growth have compressed spreads to their lowest in 13 months. Scarcity arbitrage is harder to find.

CAISO battery revenues fell 28% year-over-year to $2.78/kW-month in May. Temperatures were flat, so the decline runs through supply. Wind from SunZia's 3.5 GW new capacity created an evening surplus that compressed the discharge window batteries need.

Germany's FCA templates show renewables-pegged caps cost batteries 1.7% of revenue. But overnight charging ceilings (23:00-05:00 at 25% power) hit IRR by a full percentage point alone. That matches ramp limits and ancillary caps combined.

NYC's capacity price doubled year-over-year to $32.59/kW-month in May. For a 4-hour battery, that alone now exceeds the entire reference price in upstate zones. The city runs constrained through July.

🎧 Transmission: Most battery revenue models stop at day-ahead auctions. But Statkraft's optimisation desk shows re-trading through intraday and balancing markets can add 50% or more to annual revenue.
