Prosumer Tariffs

A prosumer tariff settles both directions of a household's electricity in one contract: the electricity drawn from the grid and the electricity fed back from the household's own generation — including what passes through a battery or an EV on the way.

A tariff in which remuneration for fed-in electricity follows a market price — typically an EPEX SPOT day-ahead or intraday index, optionally with an offset or multiplier — instead of a fixed rate set years in advance. It is the mirror image of a dynamic consumption tariff, and it can be combined with one in the same contract.

Because fixed feed-in remuneration is being replaced by market-linked models across Europe. The route differs by country — a reference market price here, a market premium there, the end of net metering somewhere else — but the direction is the same everywhere: what used to be a fixed payment set years in advance becomes a calculation, per quarter-hour and per customer. At the same time prosumers are becoming flexumers, with batteries and EVs that shift when electricity is fed in at all. Neither fits a tariff built for an annual meter reading.

Yes. Individual systems are pooled into one aggregated load with a forecast for the whole feed-in pool, which can be marketed on the day-ahead and intraday markets, handed to your trading desk as a single position, or sold locally. The revenue is allocated back to each prosumer per quarter-hour.

The same aggregation answers that case: their surplus is pooled and marketed, and they receive a fixed rate above its market value. That keeps systems in operation that would otherwise have no business case, and gives you a locally sourced product for your consumption customers.

Fixed rates, spot-indexed prices, formula products with offset or multiplier, and time-variable prices — plus rewards and bonuses on top, such as a loyalty bonus or a premium for surplus delivered in defined hours or kept in the region. All configured per tariff rather than built per customer, so the model can change when the regulation does.

Consumption and feed-in are allocated on 15-minute data, which separates self-supply from grid supply and from export. That makes each part visible in billing and in the customer app. Where the model requires it — contracting, or a community — self-consumption is not just visible but priced in its own right.

That is the contracting case, and it is supported. You own the installation on the customer's roof, the household's on-site consumption is billed at a preferred price, the surplus stays in your portfolio, and the roof lease or contracting fee is settled in the same tariff. The same applies to a battery you own and operate in the customer's home.

Yes. Stationary storage can be settled within the tariff, including flat-rate and offsetting allocation models, and bidirectional charging is supported where the vehicle feeds the home or the grid. Charging and discharging can follow the same price signals as your smart charging and HEMS products.

Yes. Systems can be pooled for direct marketing across all customer groups, with forecasts for the entire feed-in pool to support procurement and balancing.

A prosumer's surplus is usually worth more inside a community than on the grid. exnaton runs both from one platform, so a prosumer can supply a community and put the remaining surplus on a dynamic feed-in price under the same contract.

Yes. exnaton integrates with existing ERP, CRM, billing and metering systems, including SAP IS-U, SAP S/4HANA Utilities and powercloud, and returns remuneration and billing values as billable items — without replacing your IT landscape.

A single view of self-supply, consumption, export, storage, costs and remuneration, with forecasts of their own generation — as a white-label app or embedded in your existing customer portal.
