BATTERIES SUPPLY GREEN ELECTRICITY ON DEMAND - AT ANY TIME OF DAY OR NIGHT.

HOW THE GESI Giga Batteries MODEL WORKS

Charging

The GESI large-scale batteries are charged when renewable energy is available in abundance. In this respect, it is no longer necessary to throttle or switch off wind and photovoltaic systems.

Unloading

In phases when little solar and wind energy is produced, the GESI Giga Batteries step in and feed electricity into the grid. It is therefore much less necessary to buy electricity from abroad or to use fossil gas-fired power plants.

The GESI large-scale batteries are highly flexible peak load power plants that neutralize fluctuations in the generation of renewable energies. 

A GESI storage facility with a connected load of one gigawatt and a capacity of 2 gigawatts per hour cansupply around 1.8 million multi-person households with electricity for two hours. And that several times a day. The storage systems thus combine cost- and resource-efficient system stability and climate-friendly energy generation.

GESI STORES ARE THE COST- and RESOURCE-EFFICIENT BRIDGE BETWEEN THE GENERATION AND USE OF RENEWABLE ENERGIES

FOSSIL GAS POWER PLANTS ALONE WILL NOT BRING THE FLEXIBILITY NEEDED IN THE NEXT FEW YEARS

Currently, it is mainly gas-fired power plants that provide flexibility in the electricity grid. They are ramped up when too little green electricity is produced. This is essential to prevent blackouts. Due to the massive expansion of renewable energies and the shutdown of conventional power plants, the need for flexibly controllable power plants is increasing:

According to Federal Minister for Economic Affairs Robert Habeck, Germany will need an additional 25 gigawatts of connected load by 2030 in order to implement the coal phase-out as planned. This corresponds to 50 gas-fired power plants with a generation capacity of 500 megawatts each.

This gigantic infrastructure project is hardly feasible. There is a lack of gas turbines, efficient approval procedures, engineers and skilled workers. One thing is certain: if the lower limit of 25 GW of additional connected load is not reached, it will not be possible to phase out coal by 2030.

GERMANY NEEDS STORAGE CAPACITY ON A LARGE SCALE FOR THE AMBITIOUS ENERGY TRENDS

By 2045, 100% of energy generation in Germany is to come from renewable sources.

A green electricity share of at least 80% is already planned for 2030. This is extremely ambitious, especially as annual electricity demand is set to rise from 600 to 800 terawatt hours by the end of this decade.

This is primarily due to more electrified industrial processes, heat pumps and electromobility.

Calculations by the Fraunhofer Institute show that at least 100 GWh of battery storage capacity will be required as early as 2030 in order to achieve the climate targets and, in particular
