1. Short description of the technology
The AWE electrical energy storage system based on battery energy storage technology,
is including state of art superior batteries, so-called lithium yttrium - rare earth metal - based
batteries.
The energy from the battery blocks is loaded to the network (and stored from the network) through
a specially developed two-way, high-capacity (2 x 250 kW, 3-phase, 0.4 kV voltage) inverter and
transformator. The storage units can be operated and managed remotely via the AWE BSVPP (BSVPP
– Battery Strenghten Virtual Power Plant) monitoring- and process control system. Operating and
managing is a geographically independent procedure.
The equipment is going to be placed in a 40’ foot high sea container. The container includes all the
major equipment, the control system and the cooling technology, which is capable to maintain the
required temperature. The cooling technology is also operated by the control unit.
Because it’s standard size and design, the plant is easily mobile but it also can be adapted for
stationary installation. Instead of mounting in the container, the placement inbuilt environment
(buildings, halls, install to underground) can also be arranged.

2. Main applying scopes of the equipment
I. energy storage for ancillary service purpose (secondary, tertiary service)
II. interference filtering on medium and high voltage system level (filtering the
interferences which could impair and ruin the electronic interference sensitive, high
value equipments, and the possible processed products underway
III. UPS function (maintaining the uninterrupted power in the case of electrical outage;
the costumer devices are not damaging behind the energy storage, taking into the
consideration the millisecundum - level switching time
IV. the idle power absorbing function associated to all function listed above
V. mobile energy storage function with appropriate shaping – at disaster situation;
providing additional energy at certain places (exhibitions, sport games, geological
research areas, etc.)
VI. besides to PV parks, ensuring power during the night time to keep the system
connection with surrounding network(s)
3. Comparison with present technologies
Li-ion batteries – a leading edge technology
AWE decided to choose Li-ion based technologies when examined the modern solutions of
electro-chemical storage possibilities. This specific storage system compared with other
competing technologies gave the best advantages/disadvantages indicator combination.
