BATTERIES SUPPLY GREEN ELECTRICITY ON DEMAND - AT ANY TIME OF DAY OR NIGHT.
HOW THE GESI Giga Batteries MODEL WORKS
CHARGE
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.
UNLOAD
In phases when little solar and wind energy is produced, the GESI large-scale battery storage systems 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 battery storage systems are highly flexible peak load power plants that neutralize fluctuations in the generation of renewable energies.
A GESI large-scale battery storage system with a connected load of one gigawatt and a capacity of 2 gigawatts per hour can supply around 1.8 million multi-person households with electricity for two hours. And that several times a day.
The large-scale battery storage systems thus combine cost- and resource-efficient system stability and climate-friendly energy generation.
WE BUILD BATTERY STORAGE SYSTEMS ON A GIGAWATT SCALE
We plan, finance, build and operate large battery storage systems to drive forward the energy transition and increase security of supply. Our systems store green electricity when it is available in excess – and release it again when it is needed.
With capacities in the high mega or even gigawatt range, GESI battery parks make a decisive contribution to ensuring that wind and solar parks can continue to operate in so-called bright breezes. This allows the potential of renewables to be exploited much more effectively – to the benefit of the climate, the economic viability of the energy system and electricity prices.
LARGE BATTERY STORAGE FOR A SAFE ENERGY EVENT -
Selection of our CURRENT PROJECTS
Emmerthal/Grohnde (Lower Saxony)
Green electricity instead of nuclear: the nuclear power plant in Grohnde near Hamelin was finally shut down at the end of 2021. A GESI battery park is now being built in the immediate vicinity (see projection), which will ensure that the existing energy infrastructure is used sensibly and the site is strengthened again.
Output: 870 megawattsPlanned commissioning: 2028
Bergrheinfeld
(Bavaria)
It is one of the most important infrastructure projects for the energy transition: The SuedLink power line will transport wind energy from the north to southern Germany in future. It will run as far as Bergrheinfeld, making the Franconian municipality the ideal location for a GESI battery storage facility (see projection).
Capacity: 1,000 megawatts (1 gigawatt)Planned commissioning: 2029
Alfstedt
(Lower Saxony)
Storage facilities are particularly urgently needed near the North Sea coast so that wind farms do not have to be throttled or even shut down. Our battery park in the district of Rothenburg (Wümme) north of Bremen will make a significant contribution to this.
Capacity: 740 megawattsPlanned commissioning: 2029
Further projects are in the pipeline (pictures to follow).
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 Katherina Reiche, Germany will need up to 20 gigawatts of connected capacity by 2030 in order to implement the coal phase-out as planned. This corresponds to up to 40 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.
for the ambitious energy transition, germany needs large-scale battery storage capacity
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 will 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 large-scale battery storage capacity will be required as early as 2030 in order to achieve the climate targets and, in particular
- stabilize electricity generation from renewable energies
- avoid switching off or throttling wind and photovoltaic systems
- curb electricity prices and reduce CO2 emissions
