Indoor Renovation Power Supply Support in Göteborg Apartment Refurbishment
Project Context
A mid-sized residential refurbishment project was carried out in Göteborg, Sweden, involving phased renovation of a multi-story apartment building constructed in the 1970s.
The building remained partially occupied during construction, requiring work to be executed floor by floor under strict noise and safety constraints.
The electrical contractor responsible for interior works operates primarily in occupied residential renovation environments across Sweden.
Project Constraints
During early execution, the contractor relied on a combination of temporary building power and small gasoline generators. However, several operational limitations were identified:
- Generator noise was not suitable for occupied residential floors
- Indoor use of fuel-powered equipment was restricted under site safety guidelines
- Temporary building power capacity was limited during peak tool usage
- Frequent relocation between apartments required flexible power access
These constraints were most critical during interior finishing stages rather than structural renovation phases.
Pilot Deployment
To evaluate an alternative approach, the contractor introduced:
2 × WEGREEN BP360H industrial portable power stations
The units were tested in a pilot deployment setup during indoor finishing works.
Deployment approach:
- Units were used in rotation between active work areas
- Primary usage focused on interior renovation phases
- Equipment was selected based on intermittent load profiles
The system was not intended to replace site-wide power infrastructure, but to support localized indoor work sections.
Typical Load Applications
During the pilot phase, the BP360H units were used to supply power for:
- Electric drilling tools (intermittent use)
- Angle grinders (short-duration operations)
- Portable LED work lighting
- Industrial vacuum equipment (medium load)
- Small installation and finishing tools
Usage was concentrated in final-stage interior works, where mobility and noise reduction were prioritized.
Observed Outcomes
After several weeks of field usage, the contractor reported the following observations:
- Reduced reliance on gasoline generators during indoor renovation phases
- Improved suitability for work in occupied residential environments
- More flexible movement between apartment units
- Stable power supply for common interior construction tools under typical usage conditions
The system was primarily used as a supplementary power source, rather than a full replacement for conventional equipment.
Site Feedback
“It didn’t replace our existing power setup, but it allowed us to avoid using generators inside occupied apartments. That made day-to-day work easier in certain phases.”

Key Takeaway
This pilot project highlights the role of mobile energy storage systems in specific phases of residential renovation work, particularly where:
- Occupied buildings limit noise and emissions
- Indoor safety regulations restrict fuel-based equipment
- Electrical capacity is constrained during simultaneous tool usage
- Work requires frequent relocation between units
In this case, the WEGREEN BP360H units were used as a localized, supplemental power solution for indoor finishing stages, rather than a site-wide power replacement system.
Application Scope (Based on Field Use)
Based on observed deployment conditions, suitable scenarios include:
- Occupied residential renovation projects
- Interior finishing and refurbishment work
- Small to mid-sized electrical contractors
- Noise-sensitive urban construction environments
- Temporary indoor power supplementation
