Examples

👤 Consumer

Should I switch my electricity contract?

"Should I switch my electricity contract? I'm in Finland and use about 3 000 kWh per year."

Elecz returns top 3 ranked contracts with annual cost estimates, trust scores, and direct links to switch. If savings exceed zero, switch_recommended: true is set with expected EUR/year savings.

When to charge my EV?

"When is the cheapest time to charge my electric car tonight in Sweden?"

Elecz returns the best 3-hour consecutive window with average price, start and end time — ready to feed directly into a charging schedule or Home Assistant automation.

When to run the water heater?

"Milloin kannattaa käynnistää lämminvesivaraaja tänä yönä Suomessa?"

Cheapest hours endpoint returns sorted hours and the optimal window. Works identically in any language — Elecz signals are language-neutral JSON.

How much can I save?

"How much could I save annually by switching electricity provider in Norway?"

Returns expected savings in NOK/year versus median market price, with the recommended provider and a direct link to switch.

🏢 Business

Office contract comparison — Germany

"What is the cheapest electricity contract for our office in Germany? We use about 12 000 kWh per year."

Pass consumption=12000&zone=DE — Elecz returns top 3 Arbeitspreis-ranked contracts with annual cost at that consumption level. Prices are brutto ct/kWh including MwSt (19%). Regional Netzentgelt not included — it is fixed by your grid operator regardless of provider.

Annual savings report

"Calculate how much our company could save by switching electricity contracts in Sweden. We consume 25 000 kWh annually."

Returns ranked contracts with annual cost estimates and savings versus median provider — ready to include in a cost report or board presentation.

Batch job scheduling

"When is the cheapest time to run our nightly data processing jobs in Denmark this week?"

Cheapest hours endpoint returns the optimal window for the next 24h. Integrate with your scheduler to shift workloads automatically.
