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.

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.

How do I choose the right battery for peakshaving?

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.

How much does it cost to rent a battery for peakshaving?

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.

Setup

Peak Shaving

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 peak shaving work?

A battery is used to deliver these temporary peaks alongside other power sources such as generators or the grid. The battery 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 enables peak loads to be delivered without upgrading the grid or other power generation assets.

The battery is being operated through Greener’s in-house built intelligent Energy Management System that detects when demand increases. The battery responds instantly, with no delay or manual control required. This prevents overloading the grid connection or generators and lowers energy costs by avoiding expensive peak energy or diesel consumption. 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.

How does Greener apply peak shaving?

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 when it is needed.

Greener calculates the ideal setup for every project. 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 any situation where additional power is required.

Peak shaving applications across different sectors

Construction and Infrastructure

On construction sites, energy demand often fluctuates. When heavy machinery with high inrush currents such as tower cranes, hoists or pile drivers operate, peak loads can easily overload the grid connection. Generators are traditionally used as a solution. But generators have to operate all the time causing unnecessary emission, as well as be sized to the peak load causing oversizing of assets and inefficient running. A battery used for peak shaving prevents this. It provides additional power exactly when demand rises and recharges when demand drops. Peak shaving keeps operations running smoothly without interruptions, noise or emissions. Batteries remove the need for a large grid connection or oversized generators.

Events

At festivals and events, energy demand will increase and fluctuate. Examples of this are low power demand during build-up and breakdown phase and a much higher power demand during the actual event. The fluctuation during performances and mealtimes is what creates the need for peak shaving. These power peaks can overload generators or grid connections. A battery delivers temporary increases in power demand by supplying extra power when needed. This keeps the event running on clean, silent power with minimal risk of outages and significantly reduces the use of diesel generators. Using batteries in parallel can provide resilience power supplies by installing backup.

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. Mobile batteries provide temporary power support by storing energy during off-peak hours and delivering it during peak demand. This stabilises the power supply to the site and allows projects to continue without delay by boosting the grid. Peak shaving is therefore a practical and sustainable solution for grid congestion, seasonal power boosts and temporary grid reinforcement.

Rental Companies

For rental companies, being able to add batteries to their energy portfolio without CAPEX, means unlocking operational and sustainability potential.
By using a Greener battery rental companies can provide their own clients a power solution that manages peak loads and allows generators to be used more efficiently reducing emissions and fuel consumption.

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 deliver. A battery used for peak shaving stores energy during quiet periods and releases it during peak demand. This allows charging stations to serve more vehicles, even where grid capacity is limited or congestion occurs. It enables fast and reliable EV-Charging infrastructure without requiring a grid upgrade.

Greener offers mobile, scalable energy storage that is ideal for temporary charging sites, logistics hubs or fleet electrification for construction sites, ports, airports, bus depots and domestic vehicle charging.

Shore power

Ships docked at port still need to be powered and traditionally run their onboard engines to do so. That is due to limited grid capacity or power connectivity on shore. 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. Peaks in power demand can place heavy demand on the shore power connection.

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 ports and harbours. It is a simple way to ensure that vessels, houseboats and other moored facilities receive a consistent and sustainable power supply.
