Peak Shaving & Load Shifting
Reduce grid charges with battery storage
- Reduces grid charges & load peaks
- Optimum control of electricity consumers
- Guaranteed fail-safe operation
Through an intelligent Peak Shaving (peak load capping) and Load shifting (load shifting), the electricity costs or Significantly reduce grid fees. With the use of Large battery storage systems also reduce the Energy purchasing costs and the CO₂ balance sheet is improved.
Overall, the combination of peak shaving and load shifting in conjunction with a Energy Management System (EMS) efficient control of energy consumption, reduces peak loads and ensures optimized grid usage. Especially in conjunction with Large battery storage systems these strategies can be ideally implemented in a company to minimize costs and increase operational energy efficiency.
Peak shaving: targeted reduction of peak loads
Round 35 % of the average industrial electricity price is currently accounted for by the Grid charges (with an upward trend). These are determined by the highest peak load measured in the year within a 15-minute period. This is precisely where the CUBE EfficiencyUnit as EMS:
Identification and analysis of peak loads through state-of-the-art measurement and control technology
Automated control of electricity consumersto avoid load peaks
Use of battery storage systemsto cover cost-intensive consumption peaks
Peak shaving through battery storage
The CUBE EfficiencyUnit monitors and analyzes all consumption data in real time. It synchronizes the company's entire energy consumption with the battery storage system and controls charging and discharging. As soon as a load peak is imminent, the necessary energy is drawn from the battery storage system. It is then charged automatically when surplus solar power or cheap grid power is available. By flattening the peak load and discharging the storage system, the company reduces its maximum power consumption from the grid. This reduces peak load of the company and leads to lower grid charges (lower performance price) and electricity costs.
Load shifting for atypical grid usage
The grid fees for energy-intensive companies may be set individually in accordance with Section 19 (2) sentence 1 StromNEV. To this end, the local grid operator uses the data from the previous year to determine certain High load times are fixed. These vary considerably from region to region and reflect the times when there is a particularly high demand for electricity across the entire grid. As soon as companies with RLM meters and a corresponding load profile are in a position to reduce consumption in these time windows or even with your own Battery storage to stabilize the gridyou can use expect significant reductions in network charges. In this case, the company's own load peaks outside the peak load times do not increase the grid charges. With this atypical network usewhich is coordinated with the grid operator, the need for peak shaving is eliminated. The battery storage systems are therefore only used for balancing during peak load times.
Constant consumption values thanks to load shifting
Until probably the end of 2025, the grid operator will continue to reward the longest possible grid usage period with the most constant electricity volumes possible. From 7,000 hours annually, for example, the grid fees can increase by Reduce 80 or even 90 % on the service and labor prices. As the annual usage period is calculated from the total consumption and the annual peak load, peak shaving and load shifting through the use of battery storage is also worthwhile in this case. More on this in our article Strip load & strip current.
Grid fee reduction through load shifting
In addition to peak shaving, load shifting represents an overall Effective strategy to further reduce electricity costs. Here, electricity consumption is specifically reduced during periods of high grid utilization and shifted to more favorable periods with the help of large-scale battery storage systems.
In combination with an intelligent EMS, which also takes into account the company's own electricity production from a commercial photovoltaic system, the grid usage can be reduced to a minimum. More economical in the long term design. Through the targeted use of battery storage, companies not only benefit from financial savings, but also contribute to grid stability and a more sustainable energy supply.
Advantages of load shifting:
- Possibility of atypical grid usage or the band power privilege (until the end of 2025)
- Cost savings: Lower energy costs due to consumption during favorable off-peak periods.
- Grid stability: Reduction of demand peaks for a more stable electricity grid.
- Flexibility: Adaptation of consumption to low grid load.
- Energy efficiency: Optimized consumption reduces the ecological footprint.
