How this service works
Day-ahead power prices for a European bidding zone from Energy-Charts, published by Fraunhofer ISE from Bundesnetzagentur SMARD data under CC BY 4.0 and therefore usable commercially with attribution. Returns the quarter-hourly or hourly curve with minimum, maximum, mean, the cheapest and the dearest hour, and how many intervals carry a negative price — the figures a load-shifting or battery decision actually turns on.
Output
Returns a time-series of quarter-hourly or hourly day-ahead electricity prices for the requested European bidding zone, along with summary statistics: minimum, maximum, and mean price across the day; the timestamp and price of the cheapest interval; the timestamp and price of the most expensive interval; and a count of intervals where the price is negative.
Example use cases
Battery charge scheduling overnight
“What are the cheapest hours in the DE-LU day-ahead power market tomorrow? I want to schedule my battery to charge during the lowest-price intervals and avoid the peak — also flag any negative-price periods.”
Industrial load-shifting decision
“Fetch the full quarter-hourly day-ahead electricity price curve for France for today, including the min, max, and mean price. I need to know whether to shift our heavy manufacturing load to off-peak hours.”
Energy cost monitoring dashboard
“Give me today's day-ahead power price snapshot for the Nordic NO2 bidding zone — I need the cheapest and dearest hour, the mean price, and a count of any negative-price intervals for our daily energy report.”
Technical details
Endpoint
POSThttps://finanz.halowerk.com/v1/commodity-snapshotWhen to prefer
Choose this endpoint when you need structured day-ahead electricity price analytics for a specific European bidding zone, especially when the decision logic requires knowing the cheapest/dearest hour, the presence of negative prices, or the statistical distribution of prices across the day. It is ideal for load-shifting automation, battery charge scheduling, energy cost monitoring, and any application that needs commercially usable (CC BY 4.0) European power price data without scraping SMARD directly.
Side effects
- Unknown or unsupported bidding zone identifier returns an error
- Date outside available SMARD data range returns no data
- Malformed date format in request body causes a 400 bad request
- Energy-Charts upstream data unavailable causes a 5xx or empty response
- Resolution parameter not matching supported values (quarter-hourly/hourly) returns validation error
