Introduction to revenue

In the Revenue section you submit and monitor bids on Japanese power markets from Tensor Cloud. Tensor Cloud supports the JEPX day-ahead (spot) market through a direct API integration with JEPX, for both sell bids (battery discharge) and buy bids (battery charging).

Tensor Cloud also handles participation in the offline primary reserve (FCR) product of the balancing market through EPRX, for standalone and co-located battery projects, including low-voltage assets. A dedicated trading UI for this market is coming soon, as is support for the JEPX intraday market.

Prerequisites​

The Tensor team sets up the JEPX API integration for each workspace, and JEPX has to approve it manually. Before you can submit bids through Tensor Cloud, contact us with the Get support button in the top navigation bar. We will complete the registration and verify the delivery contract code on file for your workspace.

How trading works​

Bid volumes come directly from the Tensor optimization model for each delivery date. The platform builds the bids from your planned charge and discharge schedule, aggregates the volumes per grid area, and sends them to JEPX through the API. If you want to override the model for a slot, you can enter or adjust bids manually before submission. Once the day-ahead auction clears, Tensor Cloud retrieves the confirmed volumes and clearing prices and shows the outcome of each slot on the trading screen.

See JEPX spot trading for the screen, the statuses, the submission workflow, and the change history.

Revenue dashboard​

The trading screens are under Revenue in the side navigation, together with a Dashboard of your workspace's realized revenue. Choose a period with the date range picker (1 day, 1 week, 1 month, MTD, YTD, All, or a custom range; MTD is the default) and optionally narrow the view to a single grid area.

  • Net realized revenue: The net of all revenue and cost streams for the selected period. Revenue streams (for example JEPX day-ahead sales, FIP premiums, PPA offtake, and EPRX balancing market revenue) are listed separately from costs and imbalance (grid charging cost and the estimated imbalance). Each stream has a settlement state: Settled, Provisional, Estimate, or Pending.
  • Revenue & cost breakdown: A chart of revenue and costs over the period, with a net line. The time resolution follows the length of the period: 30 minutes for a single day, otherwise daily, weekly, or monthly.

Figures marked Provisional or Estimate can still change as meter data and prices are finalized. The imbalance is an estimate, calculated as (actuals minus plan) multiplied by the imbalance price. It is not the final TSO settlement.
