Peak shaving
Neargrid provides peak power for tower cranes and other construction site applications.
Renewables
Take full advantage of renewable
energy produced on site.
Cycling
Neargrid, in hybrid setups with power groups, reduces consumption and running hours.
Power your entire contruction site with a custom Neargrid battery system.
Safe and reliable power
High quality batteries ensure consistent power and safe operation even in harsh environments.
Our UPS standards result in minimal down-time, regardless of external conditions.
Microgrid on the construction site
Say goodbye to worries about weak grid connections. Our purpose-built systems create their own microgrid, allowing us to maintain a constant voltage level on site under all conditions.
Customized advice and service
Our team of professionals is ready to offer top quality advice and service to ensure our systems power your project effortlessly and worry-free.

Frequently asked
questions
What in the event of a grid outage?
The battery's autonomy is used for the entire duration of the grid outage. The system sends SMS notifications to the site management about the battery level, and our system creates a window of time during which the grid connection problems can be resolved. The construction site's continuity and productivity are guaranteed to be at their peak capacity, while the construction site does not notice the breakdown on the grid side.
Can other on-site consumers also be connected to the system?
Depending on the version you choose, several other outputs are available on the system. This is in the form of CEE outlets 32 or 63 A. Other consumers such as drainage pumps, chain park, lighting and other tools can be connected to these.
What if there is no grid connection available at the site?
If no grid connection is available, another alternative source of energy can be chosen such as solar panels or a small hydrogen or diesel powered generator. For example, a small diesel generator (+- 60 kVA) is sufficient to power 3 tower cranes via the Neargrid Force.
