Multi-vendor architecture
The platform should not depend critically on one storage, inverter, charger or vendor-cloud supplier.
WESFIN FLEX · VIRTUAL POWER PLANT
Preparing to launch
Bringing energy assets into one controllable system.
Storage, generation and controllable demand in one canonical digital model. Wesfin Flex prepares them for coordinated control, optimisation and future participation in the energy market.

Why coordination matters
Your energy assets already contain flexibility. On their own, they do not operate as one controllable resource.
Storage, solar generation, EV charging, building systems, heat pumps and industrial loads all have different constraints, protocols and operating modes. Wesfin Flex creates one control layer across that heterogeneous equipment.

What Wesfin Flex does
From an energy asset to a controllable flexibility portfolio.
The platform identifies what an asset can do, connects it to a common model, keeps control within safe limits and prepares available flexibility for local and future market scenarios.
- 01
Understand
Assess consumption or generation profiles, technical characteristics, constraints and available flexibility.
- 02
Connect
Establish metering, communications and a compatible integration path through Wesfin Edge or another approved interface.
- 03
Control
Send safe commands only within local limits and the asset’s actual availability.
- 04
Aggregate
Combine multiple resources into a coordinated portfolio while preserving each asset’s boundaries.
- 05
Optimise
Allocate available flexibility between local use cases and eligible market scenarios.
- 06
Monetise
Create economic value only where technically, commercially and regulatorily feasible.

Market scenarios
Flexibility types
One portfolio. Different forms of flexibility.
Wesfin Flex is designed to grow beyond battery aggregation into a platform for multiple distributed energy resource types.
INITIAL FOCUS
Energy storage systems
Allocate available power and stored energy between local needs and eligible market scenarios.
A planned label does not mean a production-ready integration. Compatibility depends on equipment, protocols, metering, communications and safe external control.
Economic value of flexibility
One asset. Multiple ways to create value.
Wesfin Flex does not bind an energy asset to one use case. Available flexibility can be allocated between local objectives and market opportunities.
WESFIN FLEX
The optimiser should allocate available flexibility according to prices, state of charge, technical constraints, degradation cost, local needs and commitments already made.
Actual economics depend on equipment, operating profile, metering, market prices, tariffs, degradation, imbalance exposure, regulation and contracts. Revenue is not guaranteed.

How it works technically
Different equipment. One controllable model.
Wesfin Edge normalises heterogeneous devices and protocols into a unified energy asset model so the cloud works with capabilities and constraints rather than vendor-specific register maps.

Local safety
If Internet connectivity is lost, Wesfin Edge continues safe local operation and never bypasses equipment protection.
Open industrial protocols
Core integrations rely on local industrial interfaces that Wesfin can validate and control.
Hardware abstraction
The cloud sees asset capabilities and constraints instead of vendor-specific register addresses.
Protocols
Modbus TCPModbus RTU/RS485CANMQTTREST API
Cloud platform sees
- State of charge
- Available discharge power
- Available charge power
- Telemetry quality
- Control availability
Market optimisation never bypasses hardware protection, the BMS, grid protection or local Wesfin Edge limits.

FAQ
Questions worth clarifying
01Are aggregation services already live?
No. Wesfin Flex is in preparation. Regulated services will begin only after the required procedures and a separate announcement.
02Can I apply before my battery is installed?
Yes. Projects at concept, design or construction stage can also receive a preliminary assessment.
03Is an EIC required for a pre-application?
No. If it is not known yet, the field can be left blank.
04Will Wesfin Flex work only with batteries?
The initial focus is BESS and C&I. The future architecture also includes generation, EV charging and flexible loads.
05Is income guaranteed?
No. Outcomes depend on equipment, operating profile, market conditions, metering, regulation and future contracts.
06Who can become a service partner?
Companies, sole proprietors and independent qualified specialists with relevant capabilities.
07Does partner registration guarantee orders?
No. It gathers profiles and capabilities for a future network and is not a promise of work.
08Which regions are covered?
The ambition is nationwide. We are gathering real coverage and identifying capability gaps.
09How will I learn about launch?
Provide separate voluntary consent for updates in the future form or follow the official website.
WESFIN INTELLIGENCE
News & insights
Electricity markets, regulation and flexibility technologies — concise updates on changes that may affect energy assets and business decisions.
New insights are being prepared.
Approved Wesfin Intelligence publications will appear here automatically.
START WITH THE ASSET
Assess the potential of your energy asset.
Choose the asset type. We will then ask only for the information needed for a preliminary assessment of controllability, flexibility and possible use cases.
This is a preliminary technical assessment. It is not a commercial offer, a guarantee of onboarding or an income forecast.
Assess potential
The application takes a few minutes. Technical assessment follows verification of the information you provide.
