API · integration scope confirmed individually / Market-linked tariff API · Kokusai Kogyo

Make complex Japanese electricity pricing usable.

Support customer-facing comparisons of market-linked electricity plans with calculation logic designed around the applicable plan and supply area.

Tariff data becomes more useful when equipment changes the load.

Solar generation, battery charging and BEV charging can alter when a customer purchases electricity. For a supported market-linked plan, compare the resulting purchase profile against the relevant price period, supply area and tariff formula.

Discuss the appropriate combination of tariff and equipment-simulation APIs. Your application can explain the comparison, price variability and plan eligibility while Enegaeru handles the agreed calculations.

Designed for your team’s work

Electricity retailers; energy platforms; automotive services; tariff comparison developers.

What you bring

  • Plan formula and terms
  • market-price area and reference period
  • demand data
  • adjustments, fees and applicable assumptions

What you can evaluate or receive

  • Calculate supported market-linked plans
  • compare period costs
  • expose cost components for your own interface

A practical first evaluation

Bring the exact plan terms and representative customer data. Reconcile monthly and annual totals before using the comparison in a live sales journey.

Scope to confirm

Historical market-price comparisons do not predict future bills. Confirm low- or high-voltage coverage, adjustment rules, bundled discounts and any custom development.
