Modules, inverters, trackers, mounting systems and balance-of-system components for rooftop and utility-scale plants.
Onshore and offshore turbines, blades, towers, condition monitoring and repowering services.
Residential, commercial and grid-scale storage, battery management and safety systems.
AC and DC chargers, depot charging, payment platforms and load management.
Electrolysers, fuel cells, storage, compression and refuelling equipment.
Switchgear, transformers, substations, protection and grid-edge intelligence.
Heat pumps, district heating, insulation, smart thermostats and building controls.
Electric buses, trucks, vans and the depot infrastructure that keeps them moving.
Most energy events are built for browsing. Voltwise is built for buying. Visitors arrive with live projects and a shortlist to fill, and exhibitors come ready to quote, demo and sign.
The floor is organised by project stage rather than by brand, so a developer can walk from generation to storage to grid connection without crossing the building twice.
Trade entry is free. Procurement teams with a live project can join the hosted buyer programme, which books their meetings before the doors open.
Network operators, developers, fleet owners and investors. 180 speakers across three stages; the full programme goes live in February.

We signed two distribution agreements on the stand and left Rotterdam with a pipeline that kept our sales team busy until autumn. The buyer programme alone paid for the stand.

I compared eleven depot-charging suppliers in a single afternoon. That would have taken me three months of site visits.

The quality of conversations is what sets Voltwise apart. Visitors arrive with projects, budgets and timelines, not just curiosity.

Three days, forty meetings, one shortlist. Voltwise is the only show where I meet module, inverter and mounting suppliers in the same hall.

We launched our 6 MW platform at Voltwise and the press coverage reached further than our own campaign did.
Jonas Eriksen
Managing Director
Nordwind Turbines
Our member companies come back every year because the conference programme is genuinely practical. Case studies, numbers, lessons learned.

Speaker announcements, new exhibitors and booking deadlines, roughly twice a month until the show. Nothing else.
