ENERGY STORAGE BUILDING SOLUTION
BENEFITS AT A GLANCE
DEPENDABLE
PLANNING
Taking into account the key drivers behind budget,
schedule and technical requirements, Y.Station
provides a pre-designed building layout incorporating
all elements of a large-scale storage system, reducing
project risk and enabling timely project delivery.
CUSTOMISED TO
YOUR NEEDS
The Y.Station design is technology-open: depending on
each project’s requirements, the most suitable,
best-performing and cost-efficient battery and PCS
technologies are used. It can also accommodate
multiple battery technologies for a hybrid solution.
POWERED BY Y.Q
The Y.Q platform monitors and controls real-time
operation of the Y.Station, ensuring seamless
performance of each facility. Based on advanced
IoT technology, Y.Q provides a single architecture
for controlling multiple facility elements and
communicating with external SCADA systems.
MODULAR AND
SCALABLE
Y.Station scales to ensure that the same design
efficiencies are captured from a few MWs to many
tens of MWs. Each Y.Station block can be replicated
as project sizes increase, continuously optimising
for minimal footprint and auxiliary power needs.
OPERATIONAL
PERFORMANCE
We believe that operating efficiencies deserve just as
much attention as installation efficiencies. Y.Station
prioritises auxiliary loss reduction, cost-effective
system redundancies and robust communications
across high volumes of battery racks.
24/7 MONITORING
We deliver the highest system availbility and
drastically reduce system downtime! Our operations
centre staff controls all of our deployments around
the clock. They are ready to take immediate communication and remedial actions in case of any
event disrupting system operations.
Y.STATION
PRE-DESIGNED BUILDING SOLUTION
Drawn from our experience building some of the industry’s
first utility-scale energy storage systems, the Y.Station is
our solution for larger storage projects.
It is pre-designed and pre-engineered to deliver optimised
system layout and minimise system losses, enabling
efficient project planning and faster project deplo
yment.
This modular design gives Y.Station greater flexibility in
terms of power and energy capacity, with the ability to
scale to several MW of power and several hours of duration.
Each Y.Station block can be replicated as the project size
increases, offering continued optimisation for minimal
footprint and auxiliary power needs.
Y.Q software platform
Deploying real-time responses within milliseconds, our
software supports simultaneous performance of multiple
control modes. Settings and modes can be configured
remotely via a secure web-based user interface.
Battery technology
The Y.Station consists of several AC batteries. Each AC
battery is a string of DC batteries coupled to a converter.
Thanks to extensive testing, we can recommend the most
suitable battery technology and manufacturer for every
power/energy ratio.
Best-in-class converter technology
We have selected and qualified power conversion technology that ideally meets the requirements of storage applications and blends in perfectly with all other components of
the system. The result is unmatched speed of response and
best-in-class performance.
Thermal management system
Our sophisticated thermal management system ensures
fewer parasitic losses and slower battery degradation,
while also maintaining PCS hardware within optimal
operating conditions.
Fire suppression
We deliver the highest degree of security by implementing
state-of-the-art fire suppression systems. In most cases,
we install a fully automated CO2-extinguishing system,
always guaranteeing the safety of staff and visitors on
site first.
FROM CONCEPT TO COMMISSIONING
OUR 360-DEGREE APPROACH
Younicos is your storage project partner from launch to commissioning. We take into account your regionspecific market and regulatory requirements and apply our project development and construction expertise
from more than 200 megawatts of storage projects to make yours a success.
PLANNING
ENERGY SYSTEM STUDIES
Every collaboration starts with a close look at
the client's requirements and objectives. Our
energy system studies range from defining the
optimum configuration to sophisticated
network simulations of existing infrastructure.
SYSTEM DESIGN AND ENGINEERING
We don’t simply sell you a battery – we design
and build the most reliable and efficient
energy system for your specific requirements.
We engineer it with the future in mind so that
it can accommodate your needs today and
tomorrow, as new storage applications emerge.
TESTING
We leverage the capabilities of our technology centres in Austin, Texas, and Berlin, Germany, to
extensively test your energy system under real-world conditions. Our validation and testing services
provide you with the highest level of planning reliability in terms of functionality, cost and timing.
DEPLOYMENT
PROCUREMENT

care of every aspect of
construction, including
engineering, site safety,
installation, assembly – along
with a seamless, overlapping
handover to a dedicated
commissioning team.
FACILITY COMMISSIONING

ALL-IN-ONE
ONE SOLUTION FOR ALL STORAGE APPLICATIONS
Whether you’re a utility, grid operator or independent power producer – Y.Station is the answer to your
large-scale energy management challenges. By charging and discharging, it serves as both a load and
generation source, giving you twice the flexibility as a power plant on the same interconnection.
Y.Station offers a set of services to integrate fluctuating renewables smoothly and efficiently. That adds
resilience to your grid, helping you to reduce conventional generation and achieve your emission targets.
In addition, Y.Station opens up new revenue streams for your business by making it possible to sell ancillary
services or benefit from energy arbitrage.
Last but not least, Y.Station is the key to deferred or avoided investments in grid reinforcement. It reduces
the stress on your infrastructure, for example, by smoothing demand or controlling integration of variable
renewable resources.
EXAMPLES OF APPLICATIONS
Ramp Rate control
Grids cannot easily absorb large variations from renewable generation.
Battery storage “smooths” the PV plant and strengthens the grid by
providing critical system services to buffer the impact of fluctuating
power demand and supply.
Dispatchable PV
Large-scale PV plants receive lower payments for output during the
sunniest hours. Y.Station shifts PV generation into the evening peak and
can also be dispatched to offset rapid output changes in PV generation
caused by shading and add reliability to grid operations.
Frequency response
The instantaneous differences between supply and demand cause
deviations from nominal frequency. This is due to intermittent power
generation, unpredictable loads or an unexpected failure of a power
station. Y.Station can regulate grid frequency within milliseconds
through charging or discharging short bursts of power.
Peaking capacity
By implementing Y.Station at a critical grid location, utilities can handle
peak loads that would have otherwise been served by peaker plants.
While allowing more renewable generation into the grid, Y.Station
reduces carbon emissions and is much more flexible than a peaker plant.
