Frequently asked questions
What types of B2B energy contracts does exnaton support?
exnatonPriceIQ is exnaton's price-signal module for Home Energy Management Systems. It delivers customer-specific electricity prices to HEMS platforms, allowing connected devices to automatically optimize energy consumption based on real-time electricity prices and tariff conditions.
What types of PPAs does exnaton support?
A HEMS receives electricity price signals from the utility and automatically schedules connected assets — such as EV chargers, batteries, heat pumps and solar systems — to operate when electricity is cheapest or most sustainable.
Which pricing mechanisms does exnaton support?
The service delivers a complete, all-in electricity price, including:
- EPEX SPOT day-ahead and intraday market prices
- Utility-specific premiums and risk margins
- Network charges
- Taxes and levies
- Utility tariff components
- Optional local and community prices
- Optional weather-based forecast data
Can exnaton handle PPA products combined with tranche and spot procurement?
Any tariff a utility runs. It supports fixed tariffs, time-of-use tariffs, dynamic tariffs, market-based pricing, local and community prices, and customer-specific tariff models — each resolved into a single all-in price per customer.
Does exnaton replace our existing billing system?
Yes. Where a customer is part of an energy community or a site with local generation, exnatonPriceIQ can incorporate local supply status and community allocation into the price it sends to the HEMS — so local availability, not only the wholesale market, shapes when devices run.
Can customers see how much electricity comes from PPAs, Tranches and Spotmarket?
Both. In addition to real-time prices, it delivers day-ahead and intraday forecasts for HEMS based on market and weather data, so a HEMS can plan ahead rather than only react.
How long does implementation take?
exnatonPriceIQ integrates with leading HEMS providers such as clever-PV, Solar Manager and Zerofy, and supports Home Assistant for customers running their own open-source setup, through a standardized interface. Additional partners are added as the ecosystem grows.
Can exnaton manage structured energy contracts across multiple customer sites?
Yes. Utilities can optionally expose an open Price API, giving end customers or authorized third-party developers direct access to the same real-time and forecast price data used by HEMS partners.
What business outcomes can utilities expect?
No. The utility only provides electricity price signals. Device optimization remains fully under the customer's HEMS, making implementation simple while preserving customer choice.
Does exnaton support pay-as-produced and pay-as-consumed contracts?
The customer's tariff. exnatonPriceIQ delivers customer-specific all-in prices wherever exnaton is connected to the utility's core system and holds the tariff — which is usually already the case, because exnaton handles the tariffing and pre-billing that sits in front of SAP, powercloud and other billing systems.
Can customers access ESG and renewable sourcing data?
Yes. exnaton integrates with SAP IS-U, SAP S/4HANA Utilities, and other ERP and CRM systems without requiring replacement of existing utility infrastructure.
Does exnaton integrate with SAP IS-U and SAP S/4HANA and any other ERP system?
HEMS integration helps utilities increase customer loyalty, launch more attractive dynamic tariffs, unlock demand-side flexibility, reduce peak demand, and prepare for future flexibility markets.
