Wau Off-Grid Solar PV Power Plant Project

Solar PV System and Power Generation

• The system is comprised of 22,400 high-efficiency JAM78S30-605/MR Monocrystalline PERC modules.
• Each module is rated at 605 Watts, contributing to a total simulated capacity of 13.55 MWp.
• To capture maximum power, the modules are installed at a fixed inclination angle of 13 degrees.
• The total land area required for the arrays and required safety zones is estimated at 6.3 hectares.

Battery Energy Storage System (BESS)

• The facility utilizes a 55.25 MWh Lithium Iron Phosphate (LFP) battery array, selected for its safety and long operational lifespan.
• The BESS ensures 100% load availability year-round, managing an average daily demand of 52,428 kWh.
• The storage is distributed across four dedicated battery buildings, each measuring 1,326 $m^2$.

Power Conversion and Transmission

• Four advanced Sungrow SG3400HV-MV-30 Turnkey Power Conversion Stations manage the system's grid-forming capabilities.
• Power is stepped up to 33 kV via integrated transformers to minimize energy losses during transmission.
• A 13.5 km overhead transmission line connects the plant to the city, with engineered losses kept below 2.4%.

Civil Infrastructure and Facilities

• The overall project site covers 120 hectares, with 40 hectares prioritized for Phase I development due to favorable elevation.
• Infrastructure includes all-weather 8m and 5m-wide gravel access roads equipped with drainage ditches.
• Site security is maintained through barbed-wire fencing, perimeter lighting, CCTV surveillance, and four guardhouses positioned at the site corners.
• Operational facilities include a 140 $m^2$ control room for supervision and staff welfare, a warehouse, and a groundwater well.
