Anyone dealing with the subject of battery storage may have suspected it. A study has confirmed that the use of battery storage in the home can significantly reduce the cost of network expansion at the distribution network level. For Bavaria and Baden-Wurttemberg, a brief study by Prognos AG found that it can reduce costs by more than 100 million euros per year.
Thanks to the smart battery storage system, the peak power supply around noon can be avoided. With the help of storage systems, solar energy can be fed in a grid-optimized manner. Due to the reduced feed power during peak hours, the demand for other necessary network expansions has dropped significantly, especially at low voltage levels.
This research was commissioned by BSLBATT Energy Storage, a leading manufacturer of battery storage systems.
"With our smart photovoltaic storage, homeowners can not only maximize their own solar energy but also reduce energy transition costs through predictive charging behavior," said Eric, managing director of sales and sales, marketing for BSLBATT Energy Storage.
Due to the smart and predictable charging behavior, the battery backup power supply for the home system will not completely charge with excess solar energy in the morning but can maintain idle capacity specifically for the noon peak. The basis is the automatic comparison of weather and consumption data.
This brief study is based on a conservative forecast of PV installed capacity by 2032 commissioned by the Federal Ministry of Economic Affairs and Energy. Assuming that a 6.2 GW photovoltaic system is added to the low-voltage network in southern Germany, the network cost is 120 per year and the system can save Euros.
"Because of our cost calculations, photovoltaic storage systems must be re-evaluated in the redistribution debate. If energy storage operators reduce photovoltaic power supply during lunchtime, they can reduce the burden on the entire system without having to give up renewable energy generation," the BSLBATT project Manager Bella explained.
Compared with the self-sufficient model without battery storage, it is obvious that home backup battery power supply provides economic added value and makes a significant contribution to a safe energy supply through renewable energy. Due to the low cost of network expansion, the balance of the battery storage system is always positive from the perspective of the entire system compared to the power supply model without such storage systems.
Another big step towards better integration of renewable energies is the intelligent networking of whole home battery backup power supply generation systems. In the recently introduced BSLBATT Community, producers, consumers, and storage operators are brought together so that they can supply one another with electricity. In addition to the reduced network expansion, another energy-related effect is that the electricity exchange price is smoothed and even small generation plants can switch to direct marketing.
