Why battery
storage?

Why rely on battery storage?

Battery storage systems are a key building block for a sustainable energy future and play a decisive role in the energy transition, as they help to enable the transition from fossil fuels to renewable energies, make the electricity grid more stable and efficient and cushion the increased energy demand. Battery storage systems are currently the most favourable electricity storage technology on the market. An investment in battery storage offers numerous opportunities, enables cost reductions through efficient energy management and creates additional revenue through multi-use case optimization of the assets.

Added value from battery storage

• Storage of PV electricity and
  increase in self-consumption

  The usual self-consumption rate of a PV system without a battery is often low, as the electricity generated is used directly is used directly when the sun is shining, but surpluses are often fed into the grid. With a battery storage system, the proportion of self-consumption can usually be increased by around 30%, as excess surplus solar power can be stored and used later, for example in the evening or at night. This means that more self-generated, low-cost electricity can be consumed locally and the cost of
  electricity supply costs.

• Peak shaving

  Peak load shaving refers to measures aimed at reducing short-term peaks in electricity consumption by storing energy temporarily and releasing it when needed. The goal is to minimize grid strain and reduce costs. BESS help by storing excess energy and releasing it during peak loads.

• Load shifting

  Load shifting involves moving electricity consumption from periods of high demand to periods of lower demand. This is often achieved using intelligent control and storage systems. BESS enable this by storing energy during low-demand periods and releasing it later.

• Feed shifting

  Feed-shifting refers to the adjustment of the time at which electricity is fed into the grid in order to better harmonise supply and demand. Batteries play a key role here: they store surplus electricity from renewable energies, e.g. from solar systems at midday, and release it later when demand is higher, for example in the evening. This avoids grid overloads and utilises renewable energy more efficiently.
