Summary

Trollhättan Energi, Kraftstaden Fastigheter, and Innovatum Science Park ran a practical smart-load-control pilot in a mixed residential/industrial area of Trollhättan, focused specifically on EV charging as one of the fastest-growing local load categories. Consumption was measured at 10-second resolution via smart-meter HAN ports.

Findings:

• Load control worked technically, but charging power should never be reduced all the way to zero — some vehicles interpret a full stop as the charging session ending, rather than a temporary pause.
• Different car models behave differently when power resumes after a reduction.
• Older chargers without open communication standards (APIs) cannot be remotely controlled at all — a hard technical floor, not a tuning problem — making open-standard requirements a critical procurement decision, not an afterthought.
• Property owners can add charging points without new, expensive grid connection contracts; DSOs can defer or avoid transformer-station investment; end users see minimal disruption since charging still happens, just at adjusted power during peak periods.
• Framed as primarily an organisational challenge, not a technical one: “tekniken finns och den fungerar” (the technology exists and works) — success depends on clear roles, cross-actor collaboration, and mandating open standards at procurement time.
