How this service works
Stunden mit negativen Strompreisen in den nächsten 24 Stunden.
Output
A list or schedule of hours within the next 24-hour window where the German EPEX spot electricity price is forecast to be negative, including timestamps and likely price values for each such period.
Example use cases
Battery charging window optimization
“Find all the hours in the next 24 hours when German electricity prices are forecast to go negative so I can schedule my battery storage system to charge during those periods.”
Flexible compute workload scheduling
“I need to run a large compute job overnight — can you check which hours in the next 24 hours have negative power prices in the German grid so I can schedule the job then and save on energy costs?”
Energy trading arbitrage alert
“Pull the negative electricity price forecast for the next 24 hours on the German EPEX spot market so I can decide when to buy power for our trading position.”
Technical details
Endpoint
POSThttps://energy.halowerk.com/price/negative-forecastWhen to prefer
Choose this endpoint when you need a focused, ready-to-consume list of negative-price hours in the German electricity market for the upcoming 24 hours, without needing to parse full price curves yourself. It is especially valuable for flexible-load agents, battery management systems, DePIN compute schedulers, and energy traders who want to act quickly on surplus-renewable price events. Prefer it over the broader price comparison or probability endpoints when you specifically need actionable negative-price windows rather than probabilistic signals or historical context.
Side effects
- No negative price hours forecast — returns empty list if prices remain positive throughout the 24-hour window
- Upstream SMARD/ENTSO-E data unavailable — may return an error or stale forecast
- Payment not processed — 402 challenge returned if x402 payment header is missing or invalid
- Malformed request body — schema validation error if body does not match expected structure
