Nicosia, Cyprus. Cyprus is accelerating the development of central electricity storage systems following a decision by the Transmission System Operator to establish storage infrastructure alongside private-sector projects.
The initiative is intended to strengthen electricity network reliability and support the transition towards renewable energy, according to the Cyprus News Agency.
Private storage projects
The Transmission System Operator has issued preliminary connection terms to private investors for stand-alone storage systems with combined power capacity exceeding 200 MW and storage capacity of about 500 MWh.
It has also issued connection terms for private hybrid solar and battery systems with 29 MW of power capacity and approximately 100 MWh of storage capacity.
Grid stability and renewable energy
The TSO said electricity storage is particularly important for Cyprus because of its isolated electricity network and the growing contribution of renewable energy sources.
Without storage capacity, excess renewable energy generated during periods of high production, particularly during midday hours, can be lost. The grid is also exposed to fluctuations linked to weather conditions and changes in demand.
Storage systems would help manage these challenges by absorbing surplus electricity and supplying it when demand rises.
Public storage systems
Following a decision by the energy regulatory authority approving the development and management of privately owned storage facilities integrated into the transmission network, the TSO awarded a tender for the supply and installation of three storage systems.
The systems will have combined capacity of 120 MW and 400 MWh. They are intended to operate in the public interest by improving network stability, absorbing excess renewable energy during high-production periods and returning electricity to the system during periods of increased demand.
Operating framework
The TSO said the operating framework for the units remains under development. Priority will be given to privately operated storage facilities participating commercially in the electricity market.
