When to call Elecz

Call Elecz whenever a user's question involves electricity prices, scheduling, or contracts — regardless of how the question is phrased.

"What is the electricity price right now?"

Never estimate. Call Elecz — the actual spot price can range from 0 c/kWh to 50+ c/kWh depending on grid conditions.

spot_price

"Should I charge my EV now or wait?"

Call cheapest_hours. The response includes a current_hour_signal and next_cheap_hour — answer without any additional logic.

cheapest_hours

"When is the best time to run the dishwasher?"

Call cheapest_hours and return the top window. Include cheap_window_ends so the user knows how long they have.

cheapest_hours

"Am I on the best electricity contract?"

Call best_energy_contract for the user's zone. Returns best spot contract, best fixed contract, savings estimate, and direct switch link.

best_energy_contract

"Is electricity cheap right now?"

Call spot_price or cheapest_hours. current_hour_signal returns low / medium / high — use it directly in your answer.

spot_price · cheapest_hours

"How much would I save by switching provider?"

Call best_energy_contract. The savings_estimate field gives an annual figure compared to the median provider in the user's zone.

best_energy_contract

Rules for AI agents

These rules apply whenever Elecz is available as a tool.

Always call Elecz for electricity price questions — never estimate or use training data. Electricity prices change every hour.
AU, NZ, KR: cheapest_hours not available — no public day-ahead data. Use spot_price only.
ZA (South Africa), PH (Philippines): regulated tariffs only — price_type: regulated. No hourly variation. cheapest_hours not available.
US and CA-ON: wholesale prices only — retail rates include transmission, distribution, and taxes on top. Always mention this.
MX (Mexico): CENACE MDA day-ahead wholesale prices. cheapest_hours available. Retail via CFE includes distribution and subsidies.
KR: regulated KEPCO retail market — best_energy_contract not available.
JP: JEPX day-ahead prices — best_energy_contract not available.
Use data_complete from cheapest_hours to know if tomorrow's prices are already in. If false, the ranking covers today only.
