SMA LARGE-SCALE STORAGE DAY Peak Shaving / Capacity

Mismatch between load and generation will be reflected into the grid frequency. Storage is an economically feasible option to offer this service

Providing the needed power for 1 or 2 hours per day is needed in many grids. Due to the cost reduction in storage system solution, it is very economically attractive solution
