PROJECT OVERVIEW
The project comprises a 200 MW / 800 MWh utility-scale lithium-ion BESS, configured for four-hour energy storage.
The project requires approximately 6 hectares of land, providing a highly efficient land footprint relative to its 200 MW power capacity.
The project is currently at the development stage, with the STMG grid-connection solution confirmed.
The opportunity offers investors the possibility to enter an advanced development-stage BESS project in the Italian market, either through direct acquisition or a co-development partnership.
GRID CONNECTION
STMG Status: Confirmed
The proposed grid connection includes several key infrastructure components:
- Approximately 16 months for the new 150 kV substation
- Approximately 12 months for the new 150 kV bay at the RTN “Macchialupo” substation
- Approximately 15 months for the new 150 kV bay at the RTN “Scampitella” substation
- Approximately 8 months + 1 month per kilometre for the required 150 kV transmission lines
The confirmed STMG provides an important development milestone and establishes a defined pathway toward grid connection.
