Rethinking tenant electricity: scalable system solutions for apartment blocks
How hardware-based system solutions such as the WEESS PowerTower simplify tenant electricity in apartment blocks – without complex supplier models, and with high returns.
Cut Diesel, not Power: The WEESS PowerSite Cube is a mobile battery storage system for temporary, flexible and off-grid energy supply. The system reduces diesel consumption by up to 80 per cent, cuts running costs and makes mobile energy more economical, quieter and easier to plan.

Within the WEESS portfolio, the PowerSite Cube serves as a mobile storage solution for construction sites, events, off-grid locations and temporary backup scenarios. The system is not designed for stationary building applications or large-scale grid infrastructure, but rather for situations where electricity needs to be rapidly supplied on-site, used intelligently and operated cost-effectively.
It is not just a question of having electricity. What matters is how efficiently, quietly, economically and flexibly it can be supplied locally.
The PowerSite Cube significantly reduces diesel consumption because energy is stored temporarily and released as needed, rather than running generators continuously.

The PowerSite Cube delivers energy exactly where it is needed, whether temporarily or flexibly.
Thanks to intelligent storage support, diesel consumption can be reduced by up to 80%.
Loads are specifically absorbed, energy is used according to demand and generator running times are optimised.
Lower operating costs and a quick payback period also make its use economically attractive.

The PowerSite Cube is designed for projects where mobile energy needs to be supplied quietly, cleanly, flexibly and cost-effectively.
For inner-city projects, night-time operations and construction sites where diesel generators are to be replaced or significantly relieved.
For open-air events, trade fairs and temporary event spaces where generator noise and exhaust fumes need to be avoided.
For locations without a grid connection or with unstable infrastructure, where energy must be available reliably and flexibly.
For temporary power supply during power cuts, renovation work or as a backup for critical infrastructure.

The PowerSite Cube is the right choice when mobile power supply needs to be not only available, but also quiet, emission-free, flexible and cost-effective.

The WEESS PowerSite Cube replaces the diesel generator with a mobile storage solution that operates quietly, emission-free and cost-effectively.
The PowerSite Cube is ideal for construction sites, events, infrastructure projects, off-grid locations and all temporary applications where energy needs to be supplied flexibly and cost-effectively.
The storage system handles peak loads, buffers energy and thereby reduces the load on existing diesel generators during operation. This significantly reduces running times, consumption and operating costs.
Depending on the application profile, diesel consumption can be reduced by up to 80%. In many applications, this also means that the investment can be recouped in under 12 months.
No, the PowerSite Cube is designed for hybrid operation and effectively complements existing generator structures rather than replacing them entirely in every case.
Because it makes mobile power supply more economical, quieter and more efficient — particularly where high loads, long operating times and rising diesel costs are a major factor.
