Energy storage experience
Reference installations across industries and applications
20 MW energy storage system for capacity reserves
A large thermal power plant in Chile is responsible for
providing power to an important mining region locally. To
ensure grid reliability, the power plant would curtail power from
the grid and hold back capacity to meet system response for
primary and secondary reserves. The power plant installed
a 20 MW / 5 MWh energy storage system that would allow for
an additional 20 MW of power generation to be supplied to its
customers. The energy storage system uses five 4 MW EssPro
PCS units. The system results in additional revenues for the
power plant and a more stable and reliable electrical power
infrastructure for their customers.
100 kW microgrid
For a pioneering microgrid customer in Slovakia, ABB’s EssPro
PCS enables integration with the local utility, providing a more
efficient renewable energy supply. The energy storage device
is able to regulate the power flow by discharging power to
the grid when wind and solar energy output varies, or during
unstable events, such as extreme weather conditions. This
microgrid storage solution helps maintain efficient transmission
and distribution by providing active and reactive power control.

8 MW to enhance grid stability
A large investor owned utility in California wanted to evaluate
the performance of a battery energy storage system combined
with new smart inverter technology. In 2013, the utility installed
an 8 MW – 4 hour (32 MWh) lithium-ion battery combined with
two 4.5 MVA EssPro PCS units. The installation was in one
of California’s largest wind resource areas, where as much
as 4.5 GW of wind resources are expected to come online by
2015. Some of the many project benefits of installing this battery
energy storage system include added voltage support and grid
stabilization, decreases in transmission losses and congestion,
frequency regulation support and optimization of the wind
energy output through capacity firming and smoothing.
2 MW frequency regulation solution
China’s energy demand is growing rapidly and the renewable
sources play an important role in the country’s new energy
strategy. To help maintain grid reliability and efficiency a utility
in China installed a 2 MW energy storage system for frequency
regulation. For this project ABB supplied an EssPro PCS with
advanced controls in order to help stabilize grid frequency.
240 kW systems to support two facilities
Two 240 kWh battery energy storage systems, each combined
with a 100 kW EssPro PCS from ABB, enhances the operational
efficiency at each site. The first location was a local health center
that required demand reduction, load shifting and PV integration
to reduce the facility’s energy cost. The second location was a
bottling company that required voltage support for improved
process efficiency as well as demand reduction to reduce
escalating energy bills. ABB’s EssPro PCS enables both
facilities to more effectively integrate renewables, offer greater
stability to the electric grid and allow the end customer to
take better control of their energy management.
400 kW integrated wind and energy storage system
In cold northern locations in Canada, the price of energy can
be significant due to the high cost of transporting fuel to
sites and also due to the long, cold winters and short hours
of daylight. In order to reduce energy bills and promote
the adoption of clean energy, the Cowessess First Nation
(CFN) was one of the first communities in Canada to install
a wind turbine with a battery energy storage system. ABB’s
EssPro PCS enables the battery energy storage system to
demonstrate the successful integration of a wind turbine into
the electrical grid. The project also verified that the system
is compliant with the anti-islanding standards when the grid
was absent and the wind turbine was still in production.
