Athens, Greece / London, United Kingdom – October 9, 2025 – METLEN (RIC: MTLN.L, Bloomberg: MTLN.LN, MTLN.GA, ADR: MYTHY US) and Karatzis Group of Companies are entering into a new strategic partnership, through a joint venture with ownership stakes of 49% and 51% respectively, for the development, construction, operation, and energy management of a Battery Energy Storage System (BESS) with a capacity of 330MW / 790MWh in Thessaly, Greece.

To analyse the feasibility of storage options, it is necessary to have a good understanding of the following variables: the energy efficiency of storage media; the capital cost of storage media; A feasibility assessment for microgrid projects should include all aspects of historical energy use/cost analysis, individual project identification, physical site/facilities due diligence, and projected financial and environmental benefits for projects meeting energy cost savings goals and resiliency objectives for critical loads.

Furthermore, another factor that affects the capacity and subsequently the financial feasibility of energy storage systems is the size and location of the modelled solar PV system.
Residential solar PV systems could be enhanced by employing a number of different energy storage technologies, such as electrical energy storage (EES), chemical energy storage, and thermal energy storage (TES).
Environmental Benefits The pumped storage power station uses water to generate electricity and store energy, and there is almost no emission of pollutants.
Abandoned-mine pumped storage technology can help the peak shifting of the power grid and improve the operating stability and economy of the power grid, but the construction of the pumped storage power station is restricted by geographic conditions; that is, there must be a large enough drop between the upper and lower reservoirs.
The unique features of abandoned mines offer considerable potential for the construction of large-scale pumped storage power stations. Several countries have reported the conversion of abandoned mines to pumped storage plants, and a pilot project for the conversion of an underground reservoir group has been formalized in China.
In order to evaluate the financial feasibility of integrating energy storage systems with solar PV system in detached houses, economic indicators able to compare the costs of the different storage scenarios with one another are needed.

Recently, Egypt’s Ministry of Electricity and Renewable Energy, the Egyptian Electricity Transmission Company, and a consortium comprising Infinity Power and Hassan Allam Utilities Energy Platform formally signed an agreement to jointly develop solar power projects with a total installed capacity of 1.2GW, coupled with the construction of a 720MWh battery energy storage system.
