Construction work will include the development of 10 MW of solar power along with an energy storage system with two-hour lithium-ion batteries with a capacity of approximately 13 MW / 26 MWh, as well as connection to LUCELEC’s 66 kV transmission grid.
[pdf] The Troumassee Solar Farm, expected to be completed by November 2025, is a major component of Saint Lucia’s renewable energy strategy. The project will feature 25 megawatts (MW) of solar photovoltaic (PV) technology along with 50 megawatt-hours (MWh) of battery energy storage.
[pdf] $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
