Capabilities

Tools 7

cheapest_window

Rank household action windows by cost using current Voltcast curves and optional user-supplied variable tariff inputs. Experimental carbon/balanced modes use a disclosed trailing historical production-mix profile—not a forward carbon forecast—and support no emissions-reduction claim.

Discovered
get_carbon

Carbon intensity (gCO2eq/kWh) and green score (0-100 low-carbon share) derived from the live generation mix.

Discovered
get_forecast

Probabilistic price forecast up to 7 days ahead. Returns the P50 curve and any uncertainty bands included in the connected account. Accuracy is published daily at voltcast.com/accuracy.

Discovered
get_prices

Day-ahead electricity prices in each zone's native currency and native market resolution. Connect an existing Voltcast account to access account-scoped data.

Discovered
get_realtime_prices

Explicitly labeled real-time market prices (currently WEIM), kept separate from day-ahead curves. Requires an API key.

Discovered
get_renewables

Day-ahead wind and solar generation forecasts: the TSO official forecast and Voltcast model with uncertainty bands, realized generation, and disclosed head-to-head verification. Requires the corresponding existing account entitlement.

Discovered
list_zones

List all supported European bidding zones with codes, names, and capabilities. No auth required.
