Reference Pilot 01 · Varis FlexHub · Gothenburg

Building the control layer, then integrating the site step by step

EnerVectum is developing its stand-alone site controller through the end of October 2026. The controller will then be integrated into the Varis FlexHub in stages, beginning with thermal storage, followed by PV and BESS, EV charging and finally the wider grid interface.

The objective is to turn a real commercial property into a measured reference for integrated energy flexibility, with technical performance and customer economics evaluated as the system becomes progressively more coordinated.

Current reference pilot

Varis FlexHub 01

Varis Förvaltning AB provides the host site and real-world validation environment for EnerVectum’s first integrated site-energy-flexibility reference in Gothenburg.

The programme deliberately starts with the EnerVectum controller as a stand-alone system. Site assets are then added in a controlled sequence so that interfaces, control behaviour and customer value can be measured before the next layer is introduced.

This staged approach is intended to reduce integration risk and create a clearer evidence trail for future building and portfolio deployments.

Pilot roadmap

From stand-alone controller to full site coordination

The integration sequence is intentionally progressive. Each stage adds another part of the site only after the previous interfaces and operating behaviour are sufficiently understood.

Current planning basis: stand-alone controller development continues through the end of October 2026. A four-month staged site-integration sequence is then planned from November 2026 through approximately February 2027. Timing may be refined as equipment, site readiness, commissioning and validation results evolve.
What this pilot is intended to unlock: a validated controller architecture, repeatable asset interfaces, measured site economics and a reference pathway for future commercial-building deployments.
Phase 01 · Current

Stand-alone EnerVectum controller

September–October 2026

Develop and verify the controller before wider site integration.

Core work includes data handling, interfaces, operating logic, monitoring and safe test behaviour.

Phase 02 · Integration month 1

Thermal storage integration

Planned: November 2026

Connect the controller first to the thermal-storage subsystem and establish measured charge, discharge and thermal operating scenarios.

Phase 03 · Integration month 2

PV & BESS integration

Planned: December 2026

Add solar generation and battery interfaces so electrical and thermal flexibility can begin to operate within one coordinated site model.

Phase 04 · Integration month 3

EV charging integration

Planned: January 2027

Add EV charging as a flexible electrical load and evaluate how charging demand interacts with storage, PV and site constraints.

Phase 05 · Integration month 4

Grid-aware coordinated operation

Planned: February 2027

Bring grid measurements, tariff signals and connection constraints into the wider operating logic and evaluate the complete coordinated site system.

Validation framework

What the pilot is intended to prove

The reference should establish whether coordinated site flexibility creates measurable technical and economic value, not simply whether the individual assets can be connected.

Avoidable energy cost How coordinated operation can shift consumption and storage toward more favourable periods and reduce avoidable operating cost.
Peak & grid-cost management How storage, conversion and flexible loads can reduce avoidable peaks and make better use of available connection capacity.
PV self-use How local solar production can be used more effectively through storage, controllable loads and coordinated dispatch.
Energy shifting How electrical and thermal energy can be moved in time without compromising site operating requirements.
Controller behaviour How reliably the EnerVectum controller handles data, operating logic, interfaces and staged multi-asset coordination.
Replication learning Which interfaces, control boundaries and site conditions can be standardised for future commercial-building deployments.
Project roles

One pilot, four clear responsibilities

The Varis pilot separates the host-site, R&D, thermal-storage product and integrated site-solution roles.

Varis Förvaltning AB Host site and real-world validation environment for the commercial-building pilot.
Greenco Tech AB Technology originator and R&D support, contributing technical development and validation support where required.
ThermoReserve AB Provides the TES product and thermal subsystem, including relevant thermal interfaces, monitoring and commissioning support.
EnerVectum AB Represents the integrated site solution, develops the stand-alone controller and coordinates staged multi-asset integration and validation.
Evidence first

Evidence will build with each integration stage

Before integrated testing is complete, performance objectives are treated as validation targets rather than final commercial claims.

As the programme progresses, confirmed commissioning milestones, selected operating data, economic observations, controller behaviour and replication learning can be added as verified evidence.

Could your site become a future EnerVectum reference?

We are interested in serious pilot dialogues where energy cost, peak demand, PV export, thermal loads, EV charging or grid constraints create a measurable flexibility opportunity and a credible path to replication.
