EMA
EMP customer ID
Utility customers become addressable as EMP customers for charge-point access and partner processes.
Utility power contract at the charge point
Charge at public charge points with your own power contract
Pass-through supply makes commodity power contracts mobile: utilities can give their electricity customers access to participating charge points. OB7 acts as the EMP service provider, creates the EMP customer including EMA ID, and connects contract, user access, and charge-point data with technology partners such as decarbon1ze or Banula/OLI.

From commodity customer to EMP access: OB7 connects power contract, EMA ID, charge-point access, and partner handovers.
From power customer to charging customer
The biggest lever: utilities can bring their power customers into their own contract at charge points.
For a utility, pass-through supply is not primarily a new charging product. It extends an existing customer relationship. OB7 represents the customer in the EMP context, issues or manages the EMA ID, and ensures charge-point access matches the commodity power contract.
1
Existing contract
The commodity power contract becomes the basis for access at participating charge points.
BYOP
Bring Your Own Power
The customer does not just charge somewhere. They charge with their power contract and utility relationship.
Role model
OB7 sits between the utility, the EMP role, and the technology partners enabling pass-through supply.
Our role is the customer-access and platform side: we make power customers usable as EMP customers, connect them with the right contract, and pass the required data to partners that enable the energy-market pass-through model.
Utility
Extend the commodity customer relationship
The utility can offer existing electricity and gas customers charging access that fits the existing contract relationship.
OB7
Provide EMP customer and EMA ID
OB7 represents the customer in the EMP context, manages access and identity, and connects charging sessions with the commodity contract.
Technology partner
Enable pass-through in the energy market
Partners such as decarbon1ze or Banula/OLI provide the specialized logic around virtual balancing, attribution, and market processes.
Customer
Charge with the own contract
The driver uses participating charge points not as a detached roaming case, but as an extension of their utility power contract.
Model building blocks
What pass-through supply has to solve in operations.
Partners such as decarbon1ze describe the goal clearly: free tariff choice at the charge point, mobile power contracts, and a digital layer above existing infrastructure. For OB7, that means reliably representing the utility customer as an EMP customer with charging access, EMA ID, and contract context.
Customer model
Commodity customer becomes EMP customer
The existing utility relationship is extended with charging access and eMobility identity without putting a third-party EMP in front.
Identity
EMA ID and access
The customer needs a clear EMP identifier so authorization and partner processes can work cleanly.
Authorization
Access according to the power contract
App, RFID, ad hoc flow, or account need to know which commodity contract governs charge-point access.
Readings
kWh becomes a time series
Charging-session data becomes billable energy volume with charge-point, time, and contract context.
Integration
CRM and partner connection
OB7 imports end customers from the utility or energy supplier CRM and connects them with the technology partners that enable pass-through supply in the energy market.
Customer view
Charging without breaking the contract relationship
The value appears when power customers can charge at charge points without leaving their relationship with the utility.
Implementation logic
From opened charge point to attributed kilowatt-hour.
Implementation becomes tangible when site decision, authorization, data quality, and billing are treated as one flow.
01
Activate power customers
The utility defines which commodity customers should receive charging access through the EMP context.
02
Create EMP customer
OB7 creates the customer, manages the EMA ID, and connects account, contract, and access medium.
03
Connect partners
Pass-through partners receive the data they need for attribution, virtual balancing, and market processes.
04
Enable charging
The customer charges at participating charge points according to their utility contract.
For utilities and CPOs
OB7 turns power customers into reachable EMP customers for the pass-through model.
We do not replace energy partners. We provide the platform role utilities need for customer access, EMA ID, contract context, and partner integration.
Partner-ready, not legal advice
OB7 supports EMP customer creation, EMA ID, user access, data flows, and interfaces. Balancing, market communication, supplier roles, and regulatory assessment must be clarified with technology and energy partners as well as specialist counsel.
Utility
Keep the power customer relationship
The power contract remains the anchor, even when consumption happens on the road at a charge point.
OB7
Provide EMP access
Customer account, EMA ID, app or access logic, and session context are connected cleanly inside the platform.
Partner
Make pass-through connectable
Technology partners receive the structured data they need for their pass-through processes.
FAQs
Frequently Asked Questions
Everything about pass-through supply – from roles and partners to technical implementation.
What does pass-through supply at a charge point mean?
For utilities, it means that an existing power customer can charge at participating charge points with reference to their own electricity contract. The charge point stays the same, but the charged energy volume is attributed to the right customer, contract, and partner context.
How does OB7 support this model?
In this setup, OB7 is the service provider for the EMP or utility. We create the EMP customer, manage the EMA ID, provide app or access logic, and connect the commodity contract, charging-session data, and technology partners.
Which use cases is this relevant for?
Typical cases include public charging with free supplier choice, eTruck charging infrastructure with Bring Your Own Power, fleet charging, company-car charging, and sites where several parties want to treat electricity supply and infrastructure separately.
Is OB7 itself a power supplier or market-communication provider?
No. OB7 is the white-label platform for EMP customers, user access, app, admin system, session context, and integrations. The energy-market role remains with the utility, supplier, or specialized partner such as decarbon1ze or Banula/OLI.
Which data needs to come together reliably?
EMP customer, EMA ID, commodity contract, charge point, start and end time, kWh, tariff or contract reference, and the target partner for billing or balancing. Only that connection makes the charging session usable under the right contract.
Does this need an individual review?
Yes. Pass-through supply touches contracts, metering concepts, data quality, and market roles. OB7 can prepare the technical platform side; the concrete setup should be reviewed together with energy partners and specialist counsel.
