Energy storage as a central technology of the energy transition.
The expansion of renewable electricity production accentuates the imbalance between production and consumption.
Batteries absorb electricity and feed it back into the grid when needed. They are thus a key pillar of the energy transition; a complete transition to renewable electricity is not possible without them.
Energy prices are smoothed by trading battery power and thus customer-friendly


Change also in Switzerland
In addition to home storage systems, which are also experiencing strong growth in Switzerland, additional large-scale storage systems are being commissioned. Current examples include the 10.4 MW facility in Netstal, the 4.35 MW expansion in Walenstadt, and the 11 MW facility in Mels (SG). Further commissioning is planned for 2025, such as the 30 MW battery storage facility in Kappel.
Between small home storage systems and relatively large systems, there is a niche of 0.5–3 MW storage systems. These can be installed in a small space and are economical or interesting as an efficiency boost for PV systems.
Battery storage is an important piece of the puzzle for Switzerland’s stable energy supply.

PV - self-consumption

Self-consumption
Excess Storage
Grid Reference Residual Current
When the sun shines, the photovoltaic electricity is used directly in the building.
Excess photovoltaic electricity is temporarily stored in the battery storage and can be consumed at a later time.
The energy provider of your choice supplies the residual current needed in addition to the photovoltaic electricity.

Peak Shaving
Reduction of peak loads
Breaking load peaks with battery storage
Reduction of the service price and reduction of electricity costs.
"Peak Shaving" or load peak capping reduces short-term high consumption peaks. These consumption peaks usually occur only rarely, but cause high grid and capacity costs for companies because many electricity tariffs also depend on the highest capacity called up.
When a consumption peak is looming, e.g. because several machines are started simultaneously, part of the electricity can be drawn from the battery storage instead of from the grid.

Emergency Power Supply
Ensuring operation
Replacement of existing fossil solutions
Provision of energy in the event of a power failure and ensuring production.
Compared to conventional fossil emergency power systems (e.g. diesel generators), battery storage has many advantages:
Virtually no startup time
High availability, practically no maintenance
Small space requirements, modular
Quiet, no emissions, no hazardous fuels

5
E-Mobilität
Interaction of Storage Systems
Support high load peaks, for example when charging e-trucks with batteries.
Minimize grid expansion costs.
Integrate additional storage of the e-fleet into the system (V2X).

Providing system services or peak shaving is often the preferred option from an economic point of view in the power range of 0.5-3 MW.
A combination of business models is interesting and brings benefits to everyone involved.
Battery Projects
Challenges in implementation.
Battery projects in the medium power range (approximately 0.5–3 MW) are currently rarely implemented due to their considerable complexity and lower profitability compared to large-scale projects. However, in combination with PV optimization or other models, the use of these storage sizes makes absolute sense.
Typical Challenges for a Battery Project
Lack of know-how
Lack of personnel or financial resources
Network capacity, connection options
lack of outdoor space near grid connection
Economic risks
