As soon as the industry, transport and heating sectors are decarbonized, the power grids will have to transport huge amounts of additional energy. One of the key questions is: How can the volatile generation of solar and wind power be matched locally and temporally with current demand? The answer: Battery storage can help master the challenge of the energy transition at all grid levels - from the extra-high voltage grid to the local grid.
Storage at all network levels
Climate change, climate crisis, climate collapse - these are the terms used to describe what is probably the greatest challenge of our time. The only solution is to phase out conventional energy sources. But what does this mean for the power grids of the future? The future lies in storage systems for all grid levels.

Level 1: Grid booster for transmission grids.
Supply and demand do not always match in the face of volatile solar and wind generation. Redispatch costs are inevitable without storage capability. In Germany alone, the costs amount to several 100 million euros annually! Grid boosters help to compensate for these gaps. These storage facilities are gigantic battery plants with a power range of several hundred megawatts.

euro per year are the costs for redsipatch measures in Germany alone.
Level 2: Quarter storage buffers medium voltage
Stationary storage units, so-called quarter storage units, already buffer fluctuating generation volumes at the medium-voltage level and thus make an important contribution to the energy turnaround. Energy and load management in industrial plants and distribution network sections can thus be completely reorganized. Operators can couple wind or solar farms with energy storage units to form production units and thus supply energy to the grids in a constant and plannable manner.
„With stationary storage units grid operators avoid investments, and suppliers of wind and solar energy can sell their electricity when it brings in the most profit. Power stations can create reserves and compensate for demand peaks in the grid.“
Even remote regions with weak grid connections can achieve a more stable power supply with storage technology. So-called ESS (Energy Storage Systems) can store the energy produced by various generators such as solar or wind power plants or diesel generators and release it to the grid when needed. In this way, they ensure an uninterrupted power supply.
Level 3: Batteries and charging stations for distribution grids.
The energy transition is not feasible without electromobility. This development poses enormous challenges for distribution grids in particular, which can only be overcome with intelligent charging infrastructures. For example, charging stations that provide storage accelerate the charging process and at the same time relieve the low-voltage grids. Weather-dependent fluctuations can also be balanced out with intelligent storage solutions at the local grid level. They store surplus energy and make it available again when needed.
By
2030
there will be more electric vehicles on the road in most industrialized countries than those with combustion engines.
Saving for the future
Environmental protection and the reduction of greenhouse gases, particularly CO2 , require far-reaching changes in energy production around the globe. Innovative energy storage systems are an important step on the path to the future. More about this topic can be found in our magazine ONLOAD.
