What is the difference between Grid Boost and Peak Shaving?

Peak shaving is used to absorb short periods of high energy demand within an existing grid connection. The battery stores energy when demand is low and releases it when consumption temporarily increases. This prevents excessive peak loads and keeps energy use stable and efficient. Grid Boost, on the other hand, is designed to temporarily increase grid capacity. The battery supplies extra power on top of the existing grid connection, allowing projects to use more electricity than the grid would normally allow. In short, peak shaving distributes available power more intelligently, while Grid Boost adds temporary additional power.

What is a Grid Boost?

Grid Boost is a sustainable solution for temporarily increasing the power capacity of an existing grid connection. In many situations, the available grid capacity is not sufficient to meet energy demand, such as on construction sites, charging hubs, industrial warehousing, distribution centres or temporary housing projects. With Grid Boost, grid capacity is enhanced without the need for a physical grid upgrade. The setup is often used for larger connections (400A or more) or at locations where the grid is insufficient to power the load.

How does Grid Boost work?

In a Grid Boost setup, an energy meter continuously measures the grid intake. When power demand approaches the maximum capacity of the grid connection, the battery automatically supplies additional power to the load. This prevents grid overload and maintains a stable power supply during peak periods. This can be done with multiple batteries in parallel making grid boost infinitely scalable to cater for any variable load.

During off-peak hours, or when demand is low, the battery recharges from the grid.

Grid Boost is ideal when temporary power demand exceeds what the grid can deliver, or when grid congestion is a problem. It also provides an effective solution for projects waiting for a grid upgrade.

How does Greener apply Grid Boost?

Greener supplies batteries that can be easily connected to an existing grid. Our specialists first assess the project’s power requirements and design a suitable configuration. The batteries are then delivered and installed on-site.

With our Energy Management Software, power consumption is monitored 24/7 and the batteries are controlled automatically. This ensures a reliable system that runs smoothly without interruptions.

Grid Boost applications across different sectors

Construction and Infrastructure

On construction sites, energy use is often high and fluctuating, while grid capacity is limited. Heavy electric machinery such as cranes, pile drivers and pumps requires significant power. With Grid Boost, you can instantly add temporary extra capacity to an existing grid connection without waiting months for an upgrade.

The battery automatically provides additional power when demand increases and recharges during lower demand periods. This effectively boosts grid capacity without needing changes to the setup. It prevents downtime, saves fuel and allows construction projects to continue without interruption.

Events

Events and festivals often experience strong peaks in energy demand. A standard grid connection rarely has enough capacity to handle these peaks. Grid Boost expands grid capacity with batteries, removing the need for diesel generators to cover high-demand moments.

The setup provides temporary grid reinforcement that delivers peak power when needed whilst keeping the supply stable. It creates a quiet, reliable and emission-free energy solution that can easily be scaled to the size of the event.

Grid Services

The grid is increasingly overloaded due to electrification of equipment worldwide, leading to grid congestion and long waiting times for new or upgraded connections. For many businesses, this causes delays or halts planned expansion.

Grid Boost offers a sustainable and practical solution. Adding mobile batteries to an existing grid connection temporarily increases grid capacity onsite. This reduces network strain and delivers peak power on demand, allowing existing infrastructure to be used more efficiently. For companies, it means projects can move forward even in areas with limited capacity.

During periods of low demand, the battery can also store energy, for instance from renewable sources. It then delivers that energy during high-demand periods, helping stabilise the grid and lower emissions.

EV-Charging

The shift to electric mobility requires substantial charging power, especially at logistics hubs or charging depots where multiple vehicles charge at once. Often, grid capacity is too limited to meet this demand. Grid Boost temporarily adds extra capacity to the existing grid connection.

This temporary grid reinforcement enables EV charging even at sites with limited capacity, without delays or expensive infrastructure upgrades. Electric vehicles can recharge, enabling the EV charging site to always remain operational.

Shore Power

Ships that are docked often require more electricity than the shore connection can deliver. In many ports, this is still managed using diesel generators, causing both emissions and noise pollution. Grid Boost provides a clean, emission-free solution by temporarily strengthening the shore connection with additional capacity provided by batteries.

This increases available grid capacity without emissions or noise. The setup is quick to install, scalable and easy to integrate with renewable energy sources. As a result, shore power becomes more reliable, quieter and more sustainable, even where grid capacity is limited or congestion is an issue.

FAQ

Peak Shaving is used to deliver short periods of high power demand from an existing grid connection which would otherwise be too small to power the load. The battery stores energy when demand is low and releases it when consumption temporarily increases. This prevents excessive peak loads on the grid and keeps energy use stable and efficient.

Grid Boost is designed to temporarily increase grid capacity on a larger scale. The battery supplies extra power on top of the existing grid connection, allowing projects to use more electricity than the grid would normally allow.

Yes. A Grid Boost setup can be combined with a range of energy sources such as solar panels, wind turbines and generators.

When more renewable energy is produced than is currently needed, the battery stores the surplus. When demand rises, the battery releases the stored energy. A generator can also be added to the system. In that case, the battery and grid supplies most of required energy. Having a generator connected to the system as well provides power resilience in the case of energy demand exceeding the grid and renewable capability, the generators only start when needed to recharge the battery or support longer peak periods.

Whether your grid connection is suitable for Grid Boost depends on several factors, including the size of the connection, the type of energy consumption and the available space on-site. In most cases, a Grid Boost setup is easy to implement because the battery connects directly to the existing grid in parallel.

Our experts first assess your grid capacity and maximum load. Based on this data, we calculate how much extra power is required and determine the best battery configuration for your project.

A Grid Boost setup offers a much more sustainable, quieter and efficient way to supply extra power than a diesel generator.

- Grid Boost operates completely emission-free. The battery produces no CO₂, nitrogen oxides or particulate matter, while a diesel generator continuously burns fuel and emits pollutants. This makes Grid Boost ideal for projects that must meet stricter environmental standards.
- Batteries run almost silently, making them well suited for urban environments, events or projects near residential areas and nature reserves.
- A diesel generator often runs even when full power is not required, wasting fuel. The battery delivers exactly the amount of power needed and recharges during off-peak hours, creating a much more efficient system.
- A battery can be combined with renewable sources (or a small generator as backup), forming a flexible setup that automatically adapts to changing energy demand.

Grid Boost can be used either temporarily or as a long-term solution, depending on the project and its energy needs.

In many cases, it serves as temporary grid reinforcement while waiting for a grid upgrade or during periods of grid congestion when extra capacity is not yet available. The battery bridges this period, allowing work to continue.

In locations where the grid is permanently undersized or frequent peaks occur, the battery can be used long term as an extension of the grid connection. In that case, the system becomes an integral part of the local energy setup, often in combination with renewable energy sources such as solar or wind power.
