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.
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.
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.
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.
Thermal storage integration
Planned: November 2026
Connect the controller first to the thermal-storage subsystem and establish measured charge, discharge and thermal operating scenarios.
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.
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.
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.
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.
One pilot, four clear responsibilities
The Varis pilot separates the host-site, R&D, thermal-storage product and integrated site-solution roles.
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.
