Zero-emission power where projects need it
ONENSYS provides reliable onsite power and charging capacity where no grid connection is available, grid capacity is insufficient or delayed, and conventional generators are unsuitable due to emission limits, noise restrictions or sustainability goals.
Explore the main applications below.
Grid limitations
Your operation needs power, but the grid cannot always provide it.
A connection may be unavailable, delayed or too small for the required load. At remote, temporary or mobile locations, a grid connection may not be viable at all. This can limit expansion, electrification, charging and day-to-day operations.
ONENSYS assesses your power needs and designs an onsite energy system that provides the required capacity wherever the grid is insufficient or unavailable.
Infrastructure
Reliable mobile power for infrastructure projects that move along roads, dikes, railways or waterways.
These construction projects often move from one location to the next. A fixed grid connection is therefore rarely practical, while emission and noise requirements increasingly restrict conventional generators. ONENSYS provides mobile H2-Powergen setups that move with the project and keep operations powered throughout the work.
Construction
Reliable onsite power for construction sites where no grid connection is available, grid capacity is limited and emission requirements apply.
Construction sites increasingly need power for electric excavators, wheel loaders, cranes, rollers, tools, lighting and temporary facilities. ONENSYS helps contractors keep work moving with onsite energy systems that fit the project location, power demand and emission requirements.
Manufacturing & Processing
Reliable onsite power for operational expansion or temporary operations.
Industrial sites may need extra power when the existing grid connection is too limited or when zero-emission operation is required. ONENSYS helps analyse the demand and configure an onsite system that supports operational expansion or temporary operations.
Charging hubs
Reliable onsite power for charging vehicles and equipment at depots, yards and distribution hubs.
The electrification of vehicles and equipment is increasing power demand at logistics sites. Where the existing grid connection cannot support the required charging load and additional capacity is delayed, ONENSYS provides zero-emission onsite power to supplement the grid and keep electric operations moving.
Other sectors
Events
Reliable temporary power for festivals, venues and public events.
Festivals, public events and temporary venues require reliable power for stages, lighting, catering, facilities and charging. ONENSYS provides mobile onsite power that reduces local emissions and noise while supporting operations throughout the event.
Backup power
Reliable support power for operations where continuity is critical.
Industrial facilities, data centres, healthcare locations and other critical operations may require additional capacity when grid power is unavailable or insufficient. ONENSYS provides zero-emission support power with monitoring, operational service and agreed performance levels focused on keeping essential operations running.
Ports
Reliable zero-emission power for shore power, equipment and temporary port operations.
Ports are under pressure to reduce emissions while electricity demand increases. With AFIR and FuelEU Maritime driving the rollout and use of shore-side electricity from 2030 for certain container and passenger vessels, ports and terminals will need reliable zero-emission power solutions. ONENSYS can support shore power, port equipment charging and temporary mobile power where grid capacity is limited or not available.
Frequently asked questions
The grid connection for my project is delayed — can ONENSYS provide power in the meantime?
Yes — this is one of the most common situations we solve. We assess your power demand and configure an onsite energy system that delivers the capacity you need while the grid connection is unavailable, insufficient or not yet ready, so your project can start on time.
Do I need a fixed grid connection to use an ONENSYS system?
No. Our systems operate off-grid and grid-connected. For temporary and mobile projects we provide reliable power without depending on fixed infrastructure, and the setup can move with your project.
My site must meet zero-emission or Natura 2000 requirements. Is that possible without stopping work?
Yes. We configure zero-emission onsite power that supports compliance with Natura 2000 restrictions, SEB requirements and procurement criteria — without bringing your operation to a halt. Where conventional generators are no longer allowed, this is exactly the gap we fill.
I'm not sure which challenge applies to my project. How do I find out?
Many projects face several overlapping constraints: limited grid capacity, emission requirements and tight timelines. Contact us to assess your onsite power challenge. We evaluate your energy and power demand, grid situation and emission requirements, then explore the right power setup for your site.
Can ONENSYS guarantee system performance?
Depending on the project and operating requirements, ONENSYS can agree contracted performance levels covering areas such as power availability, monitoring, maintenance and service response. The exact commitments and conditions are defined in the project agreement.
