We are building a virtual power plant.
We invite you to become part of its collective power.
Join the VPPNEURC licence granted 13.10.2026, commercial services not live yetDay-ahead, intraday and balancing markets, and ancillary services. The market price changes every hour. Commercial aggregation services are not live yet.
How value is createdThe cloud platform brings different assets into one portfolio and shares the available flexibility between local tasks and market scenarios.
What Wesfin Flex doesWesfin Edge on site turns different devices and protocols into one model. Optimisation never bypasses the BMS, grid protection or local limits.
Technical detailsThe initial focus is energy storage and industrial controllable load. Other asset types are marked as future scope.
Types of flexibilitySoC means state of charge. You define a reserve that Wesfin Flex does not use: if it is 30%, for example, the charge below that level stays yours and only the rest can work. The 30% here is only an example.

Is your asset working as much as it could?
A battery often just holds its charge in case of an outage. Peak consumption is expensive, and the market price changes every hour. Keeping up with that by hand is hard, especially with mixed equipment. Wesfin Flex is preparing one control layer: you define a reserve that Wesfin Flex does not use, and the rest of the flexibility can work where that is technically and legally allowed.

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.

Reserve in this model: SoC 30%. Wesfin Flex does not use it.
Prices: day-ahead market. Data source: Market Operator JSC. The charging and discharging hours are calculated by the Wesfin optimiser for a model battery, and the state of charge is modelled. This is not data from a real installation and not a revenue forecast, and commercial services are not live yet.
The optimiser should allocate available flexibility according to prices, state of charge, technical constraints, degradation cost, local needs and commitments already made.
On-site value

- Higher self-consumption
- Solar-surplus management
- Managed EV charging
- Thermal inertia and heat storage
Market scenarios

Actual economics depend on equipment, operating profile, metering, market prices, tariffs, degradation, imbalance exposure, regulation and contracts. Revenue is not guaranteed.
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.
Understand
Assess consumption or generation profiles, technical characteristics, constraints and available flexibility.
Connect
Establish metering, communications and a compatible integration path through Wesfin Edge or another approved interface.
Control
Send safe commands only within local limits and the asset’s actual availability.
Aggregate
Combine multiple resources into a coordinated portfolio while preserving each asset’s boundaries.
Optimise
Allocate available flexibility between local use cases and eligible market scenarios.
Monetise
Create economic value only where technically, commercially and regulatorily feasible.
One portfolio. Different forms of flexibility.
Wesfin Flex is designed to grow beyond battery aggregation into a platform for multiple distributed energy resource types.
Illustration
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.
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.
Multi-vendor architecture
The platform should not depend critically on one storage, inverter, charger or vendor-cloud supplier.
Local safety
If Internet connectivity is lost, Wesfin Edge continues safe local operation and never bypasses equipment protection.
Hardware abstraction
The cloud sees asset capabilities and constraints instead of vendor-specific register addresses.
Market optimisation never bypasses hardware protection, the BMS, grid protection or local Wesfin Edge limits.

From building an energy asset to managing its flexibility.
Wesfin Flex
Connection, coordination and optimisation of distributed-energy flexibility.
Wesfin Service
Technical support, service capabilities and field maintenance for energy assets.
Technical capabilities closer to energy assets.
We are building a network of service companies and qualified specialists able to support equipment integration and maintenance across Ukraine.
The region list communicates target future coverage, not a confirmed current count or status of partners.
Commercial aggregation services are not live yet.
Wesfin Flex LLC was granted its aggregation licence on 13 October 2026 and is completing market onboarding. Regulated services activate after the required procedures and statuses are complete.

Questions worth clarifying
Do I lose control of my asset?
Partly, by design. Under the agreement you give Wesfin Flex the right to control your equipment, but only with agreed commands and within agreed limits. Your agreement sets a reserve that Wesfin Flex does not use, and equipment protection always comes first. If there is a threat to people, equipment, the grid or a critical process, you can immediately limit or stop remote control. You can change the reserve through the cabinet; if you do so after an irrevocable market commitment, only documented costs caused by the change can be passed on to you.
What do I sign, and when?
Registering is not a contract. Participation starts with a separate agreement on taking part in an aggregated group, signed with a qualified electronic signature (КЕП). Its standard form for companies and sole proprietors is published on the regulatory information page, and individual terms are agreed in the annexes. Signing alone does not admit your equipment to the market: commercial operations begin only after the checks in the agreement are complete.
Can I leave?
Yes. Send a request through the cabinet, or by email to flex@wesfin.energy with a qualified electronic signature (КЕП). Leaving is completed as soon as possible, and no later than 21 calendar days after we receive the request, followed by a final settlement. An exit fee is possible only within the law and must be proportionate. It cannot exceed Wesfin Flex’s direct documented losses or costs, including services already provided, and Wesfin Flex has to prove them. Any specific terms are set out in Annex 3.
How much does it cost?
The commercial model and remuneration are agreed individually in Annex 3 to the agreement. Possible components: a share of the net result, a management fee, a trading fee, a platform fee, and Wesfin Edge and integration.
What happens after I register?
If anything else is needed, our manager will call you. We will tell you about the next steps by email or another way; we are not naming dates yet.
Are aggregation services already live?
No. Wesfin Flex is in preparation. Regulated services will begin only after the required procedures and a separate announcement.
Can I register before my battery is installed?
Yes. Projects at concept, design or construction stage can also register.
Is an EIC required to register?
No. If it is not known yet, you can register without it.
Will Wesfin Flex work only with batteries?
No. The initial focus is energy storage and industrial controllable load. The future architecture also includes generation, EV charging and flexible loads.
Is income guaranteed?
No. Outcomes depend on equipment, operating profile, market conditions, metering, regulation and future contracts. No revenue split applies by default.
How will I learn about launch?
Provide separate voluntary consent for updates in the future form or follow the official website.
