Pure Energy Ltd., a company under the Energy Division of Golyan Group, has established state-of-the-art grid-connected solar PV plant at Raniyapur in Khajura Rural Municipality of Banke District, Lumbini Province. When this plant came into operation, this was the largest solar PV plant in the country.
The solar plant is divided into two blocks, Block-1 and Block-2, each designed with an installed capacity of 10 MW AC and 12.5 MW DC. The project site benefits from favourable climatic conditions, with an average annual solar insolation of 5.71 kWh/m²/day, making it highly suitable for efficient solar generation.
Block-1 is located between 28°10’22” to 28°10’44” N latitude and 81°35’21” to 81°35’52” E longitude, is equipped with 19,020 numbers of bifacial double-glass mono PERC modules (655–660 Wp each) made by Canadian Solar, mounted on fixed-tilt MMS structures (19° tilt), covering an area of about 59,083 m². This block is supported by 34 Sungrow string inverters (295 kW each) and two 6 MVA ONAN transformers manufactured by Wilson Power. It generates approximately 20.23 GWh of clean electricity annually. This plant is in operation since Paush 2080.
Similarly, Block-2 is located between 28°09’29” to 28°10’01” N latitude and 81°34’50” to 81°35’10” E longitude, uses 19,424 TrinaSolar bifacial double-glass mono PERC modules (640–645 Wp each) installed on fixed-tilt MMS structures (18° tilt), covering an area of about 60,337 m². Its power system is backed by 46 Solis string inverters (220 kW each) and two 6 MVA ONAN transformers supplied by Hammond, with an identical annual generation capacity of 20.23 GWh. This plant is in operation since Baisakh 2080.
The combined output of the two plants is evacuated via a 17 km long, 33 kV double-circuit transmission line, which connects to the Kohalpur Substation of NEA.
