How this service works
Day-ahead wholesale electricity prices (15-min or hourly) for a European bidding zone and up to 31 days, in local time, with daily min/max/mean, negative-price slots and the cheapest and priciest N-hour window. Use when scheduling EV charging, heat pumps, batteries or flexible load, or when asked what power costs tomorrow in Germany, France, Netherlands and other EU zones.
Output
Returns a structured response containing per-interval (15-min or hourly) electricity prices in EUR/MWh in local time, along with daily summary stats (min, max, mean), a list of negative-price time slots, and the start time and average price of the cheapest and most expensive N-hour contiguous window for the requested zone and date range.
Example use cases
EV overnight charging optimization
“Can you pull tomorrow's day-ahead electricity prices for the Netherlands and find the cheapest 3-hour window overnight so I know when to schedule my EV to charge?”
Heat pump scheduling in France
“What are the day-ahead power prices in France for the next 3 days, and highlight any negative-price slots or the cheapest 2-hour blocks each day so I can pre-heat my home efficiently?”
Battery arbitrage window identification
“Get day-ahead wholesale electricity prices for DE-LU from 2025-07-14 to 2025-07-20 with a 6-hour window, so I can see the cheapest and priciest 6-hour blocks each day for my home battery arbitrage strategy.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/power/day-ahead?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need day-ahead electricity price data for European bidding zones with built-in analytics like cheapest/priciest N-hour windows and negative-price detection, especially for scheduling flexible loads like EV charging, heat pumps, or battery storage. Prefer this over raw ENTSO-E API access when you want pre-computed daily summaries and window analytics without writing your own aggregation logic. Best suited for agents automating energy optimization decisions rather than pure financial market analysis.
Side effects
- Missing required 'zone' parameter returns a validation error
- Invalid zone code (not in allowed enum) returns a 400 error
- Requesting more than 31 days returns an error
- Requesting tomorrow's prices before ~13:00 CET may return incomplete or unavailable data as ENTSO-E publishes results around that time
- Date format not matching YYYY-MM-DD returns a parsing error
- Service unavailable on render.com cold starts may cause initial latency spikes
