Peak Shaving

Q: How does peakshaving with batteries work?

Peakshaving with batteries works by making smart use of energy storage. The battery connects to the power grid, renewable energy sources or a generator. During off-peak hours, when energy demand is low, the battery charges. When consumption rises, the battery automatically delivers extra power to fill the gap, flattening peaks and reducing load on the grid connection. This keeps power demand more stable, helping to lower costs and prevent grid overload. It makes peak shaving an effective solution for grid congestion at locations with limited grid capacity. Battery peakshaving can be applied in construction projects, events, EV charging sites, temporary power supplies and shore power solutions. The battery provides temporary power support exactly when it is needed, with zero emissions and no noise.

Q: What is the difference between peakshaving and loadsharing?

Peak shaving and load sharing both help use energy more efficiently and reduce peak loads, but they work in different ways. In peak shaving, energy peaks are flattened, which reduces the load on the grid. This is especially useful in cases of grid congestion, limited connection capacity or projects that need temporary power support. Load sharing distributes energy demand across multiple sources. The battery works together with other energy sources such as solar panels, wind turbines or a generator. The Energy Management System (EMS) ensures that each source contributes optimally to the total power supply. This means there is always enough power available, while maintaining the most sustainable setup possible. Both techniques help use energy more efficiently, reduce CO₂ emissions and relieve pressure on the grid. At Greener, these solutions are often combined into a hybrid energy system.

What is peak shaving?

Peak shaving is a smart way to handle spikes in power demand. On many sites, the grid connection isn’t strong enough to handle all consumption peaks. Think of moments when several machines start at once, when a large stage is fully lit, or when multiple electric vehicles charge simultaneously. These moments create peak loads, which can be managed efficiently with peak shaving.

How does it work?

A battery is used to absorb these temporary peaks. It charges during off-peak hours, such as at night or when energy demand is low. When consumption rises, the battery automatically supplies extra power. This relieves pressure on the grid and reduces peak loads.

The setup operates fully automatically through an intelligent Energy Management System that detects when demand increases. The battery responds instantly, with no delay or manual control required. This not only prevents overloading the grid connection but also lowers energy costs by avoiding expensive peak consumption.

How does Greener apply this?

Greener uses mobile batteries as a temporary or long-term solution for grid congestion or limited connection capacity. Our batteries can connect directly to the grid or integrate with solar panels, wind turbines, or generators. This creates a flexible, emission-free energy system that always delivers the right amount of power.

For every project, Greener calculates the ideal setup. The battery charges during low-demand periods and delivers power during peaks. This approach works perfectly for construction sites, events, EV charging, temporary housing, or maritime applications.
Through real-time monitoring with our in-house software, we continuously track energy consumption. This allows us to predict exactly when peaks will occur and ensure that sufficient power is always available.

Applications across different sectors

Construction and Infrastructure

On construction sites, energy demand often fluctuates. When heavy machinery such as excavators, tower cranes or pile drivers operate at the same time, peak loads can easily overload the grid connection. A battery used for peak shaving prevents this. It provides additional power exactly when demand rises and recharges when things quiet down. This keeps operations running smoothly without interruptions, noise or emissions. This energy storage also removes the need for a heavier grid connection and helps reduce emissions.

Events

At festivals and events, energy demand can rise sharply. Examples of when this happens are when a performance starts, during stage setup or during light shows. These peaks can overload generators or grid connections. A battery absorbs these temporary surges by supplying extra power when needed and flattening out the peaks. This keeps the event running on clean, silent power with minimal risk of outages and significantly reduces the use of diesel generators.

Grid Services

For many companies and local authorities, grid congestion is a growing challenge. The grid often lacks the capacity to meet full energy demand, and waiting times for a grid upgrade can be long. A mobile battery provides temporary power support by storing energy during off-peak hours and delivering it during peak demand. This stabilises the grid and allows projects to continue without delay. Peak shaving is therefore a practical and sustainable solution for grid congestion and temporary grid reinforcement.

Rental Companies

For rental companies, offering a peak-shaving option adds real value to their portfolio. By providing clients with a battery that manages peak loads, they can use generators more efficiently and reduce emissions. The battery energy storage system (BESS) delivers extra power when needed, cutting fuel use and maintenance costs. It is an attractive and sustainable power solution for clients who want temporary power without unnecessary emissions.

Greener supports rental companies with advice, delivery and monitoring, enabling them to offer sustainable power solutions to their clients and meet the growing demand for emission-free energy.

EV-Charging

Charging several electric vehicles at once often causes high peaks in power demand, which the existing grid connection is not always able to handle. A battery used for peak shaving stores energy during quiet periods and releases it during peaks. This allows charging stations to serve more vehicles, even where grid capacity is limited or congestion occurs. It enables fast and reliable charging infrastructure without requiring a grid upgrade.

Greener offers mobile, scalable energy storage that is ideal for temporary charging sites, logistics hubs or pilot projects for electric transport.

Shore power

Ships docked at port sometimes require a sudden increase in power, for instance when starting engines or operating heating and cooling systems. These peaks can place heavy demand on the shore power connection. A battery offers an effective solution by keeping the energy supply stable, clean and quiet. It provides extra power when needed and recharges when demand is low.

The battery can draw energy from the grid or from renewable sources such as solar or wind power. This makes shore power more reliable and significantly reduces emissions and noise levels in the harbour. It is a simple way to ensure that vessels, houseboats and other moored facilities receive a consistent and sustainable power supply.

The right battery for peak shaving depends on three key factors: required power output (kVA), energy capacity (kWh) and the duration of the peak load. For short but heavy peaks, such as those caused by construction machinery or fast chargers, a battery with high power output is important. For longer peaks, such as at events or temporary housing, a larger storage capacity is required.

At Greener, our experts help determine the right battery and setup. Our Energy Management System analyses expected usage, predicts peaks and calculates the most efficient configuration. The result is an emission-free, efficient solution tailored to your project.

For businesses, peak shaving offers a smart way to use energy more efficiently and reduce costs. By reducing peak loads, the grid is less heavily burdened, keeping energy usage stable. This provides both financial and sustainability benefits.

Main benefits:
- Lower energy costs
- No need for grid reinforcement
- Reduced CO₂ emissions and fuel use
- Reliable and stable power supply

The cost of renting a battery for peakshaving depends on your energy demand, required power output and project duration.

For projects with high peak loads, using a battery is often cheaper than requesting a grid upgrade. The battery absorbs temporary peaks and avoids peak tariffs. Renting a battery is also flexible. You only pay for the capacity you need and for the period you use it.
In addition to lower energy costs, peak shaving brings indirect savings such as reduced fuel consumption, less maintenance and lower CO₂ emissions.

Smart software is essential for peak shaving. It ensures that the battery knows exactly when to charge and discharge, without any manual action required.

At Greener, we use our own Energy Management System (EMS). This software is designed to manage energy storage as efficiently as possible. It continuously measures energy consumption and automatically decides when the battery should supply or store power.

Users can access the online platform at any time for real-time insights into energy usage, CO₂ savings and battery performance.
