Energy storage facility of a cumulative installed capacity of 384 MW, storage capacity allowing a net annual electricity generation of 250 GWh. The storage will consist of several smaller units (~32-64MW) located in Slovakia (central Europe).
Considering energy density, charge and discharge efficiency, life span, and ecofriendliness of devices, the battery storage shall be based on Lithium-ion technology. In smaller scale, to increase the energy density of the batteries, the project also foresees the implementation of Lithium-sulphur technology.
The ELSEA project is enlisted on preliminary ENTSO-E’s TYNDP 2020
and is published on the website of ENTSO-E.
The ELSEA project is a candidate for the 2021 PCI list.
Intermittent generation (wind, solar) causes difficulties for its dispatching as well as increases the complexity of network management. Currently there are no sufficient capacities to store excess energy even for short-time periods, what leads to increased demand for ancillary services and triggers inefficiency in energy utilisation.
Energy transition requires massive investments into transmission and distribution infrastructure.
High volatility on energy markets makes power cost prediction very difficult. Currently consumers have no relevant measures to manage peak consumption.
A negative impact on environment is caused by CO2 intensive power generation that aims to provide ancillary services for the grid.
Decentralised generation units in EU citizens‘ homes would be more effective if they could accumulate the surplus power and supply it when needed.
ZSE Energia, Slovakia based energy company, has 95+ years of experience from the electricity market in Central Europe. The company is one of the most innovative power and gas suppliers in the region. In 2019, ZSE Energia serves more than 1 million customers and delivers annually 9 TWh of energy.
The Project has been supported by the national TSO and the Ministry of Economy at its launch
