The 100MW Solar PV Power Plant with a 40MW/120MWh Battery Energy Storage System in Rajnandgaon, Chhattisgarh, represents a milestone in renewable energy deployment.
Key Project Features of 100 MW Solar PV Power Plant with 40MW/120MWh Battery Energy Storage System: Project Completion time: Completed in 18 months. Total CO2 Saved: Saved 175,422.68 tons of CO 2 emissions annually. Innovative solution providing /120MWh battery backup for 3 hours during non-solar peak hours.
250 MWh is the energy capacity —meaning the battery can supply 100 MW continuously for 2.5 hours. Power Conversion System (PCS): Converts DC (battery) to AC (grid) and vice versa. Battery Cells & Racks: Store energy chemically, usually in lithium-ion (LiFePO4 or NMC).
Solar PV and battery storage facilities require no fuel and produce no waste. The offsite requirements are limited to an interconnection between the facility and the transmission system as well as water for the purpose of cleaning the solar modules. Cleaning is regionally dependent.
The aluminum rails and module clamps are imported from China and subject to 25% tariff. Each module is paired with a microinverter rated at 330 W ac, giving the PV system a rated AC power output of 6.6 kW ac, which corresponds to an inverter loading ratio of 1.22.
The $/kWh costs we report can be converted to $/kW costs simply by multiplying by the duration (e.g., a $300/kWh, 4-hour battery would have a power capacity cost of $1200/kW). To develop cost projections, storage costs were normalized to their 2022 value such that each projection started with a value of 1 in 2022.
