The project, owned and operated by AES Distributed Energy, consists of a 28 MW solar photovoltaic (PV) and a 100 MWh five-hour duration energy storage system. Battery storage will help integrate this variable energy source.
CEA has proposed draft construction standards for solar, floating solar, onshore wind, offshore wind and BESS projects. The framework introduces technical, safety, performance and monitoring norms, with implementation proposed from April 1, 2027.
The energy storage system consists of a battery system, PCS cabinet, transformer cabinet, distribution cabinet, fire cabinet, air conditioning, emergency exhaust, lighting and other equipment. All equipment is arranged in a container.
As of Q2 2024, commercial-scale lithium storage systems in Cerro Port range from $280 to $380 per kWh, influenced by: Industry Insight: Paraguay's National Energy Policy aims for 60% renewable integration by 2025, creating a $120 million market for energy storage solutions.
Factories running two or three shifts — or operating continuously — consume significant electricity outside daylight hours when solar generation is zero.
In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per.
Solar energy with battery storage refers to systems that pair photovoltaic (PV) panels with energy storage devices—typically lithium-ion batteries—to store excess solar power generated during the day. This stored energy can then be used during the night, cloudy days, or power.
