This dataset represents electricity generation from centralized photovoltaic (PV) power plants in a specific region. Centralized PV power plants are typically constructed on sites such as deserts, barren land, mountainous areas, and water surfaces, and the generated electricity is delivered to end users through the public grid under centralized dispatch, typically via grid interconnection voltages of 35 kV or 110 kV. The centralized PV systems considered here are represented by monofacial single-glass and bifacial double-glass crystalline silicon PV modules installed on open-ground photovoltaic power plants. Electricity generation is adjusted based on site-specific first-year equivalent full-load hours of fixed-tilt PV systems and the module lifetime. The service life of PV electricity generation components follows official regulatory standards, with a technical service life of 25 years for single-glass modules and 30 years for double-glass modules.
