The Daraundi River, as the primary water source, plays a crucial role in the plant’s functionality, with its flow characteristics directly impacting the generation capacity.

Geography and Hydrology

The Daraundi A Hydropower Station is situated within the Gorkha District of Nepal, a region characterized by significant topographical variation and dense river networks. The facility operates as a run-of-river hydroelectric plant, a design choice that relies heavily on the natural flow regime of the water body it intercepts. According to authoritative sources, the plant is located on the Daraundi River. This specific waterway serves as the primary source of hydraulic energy for the 6 MW installation operated by Daraundi Kalika Hydro. The geographical placement within Gorkha District places the station in a zone where river gradients are typically steep, favoring run-of-river schemes that minimize the need for extensive reservoir storage compared to reservoir-based hydroelectric projects.

River System and Confluence

The hydrological function of the Daraundi A station is defined by its position on the Daraundi River. The river system in this part of Nepal is part of a larger drainage network that feeds into the major river basins of the country. The Daraundi River eventually reaches a confluence with the Marshyangdi River. This confluence is a key geographical marker for the lower reaches of the Daraundi watercourse. The Marshyangdi River itself is a significant tributary in the region, contributing to the broader water resources of the Gandaki river basin system. The interaction between the Daraundi and Marshyangdi rivers influences the flow characteristics that the hydropower plant must manage. As a run-of-river plant, the Daraundi A station does not create a massive lake-like reservoir but instead uses the natural flow of the Daraundi River, channeling it through turbines before returning the water to the riverbed or a short tailrace channel. This operational mode is typical for the topography of Gorkha District, where land availability for large reservoirs is often limited by steep valley walls.

Hydrological Parameters

The operational capacity of the plant is rated at 6 MW. This capacity is directly dependent on the hydrological parameters of the Daraundi River, including its annual average flow and the head available at the site. The plant has been operational since its commissioning in 2016. The run-of-river design implies that the power generation is variable, fluctuating with the seasonal changes in the river's discharge. While the specific numerical values for the catchment area size and the exact annual average flow rate are critical for detailed hydraulic engineering analysis, the primary documented facts confirm the plant's reliance on the natural flow of the Daraundi River within the Gorkha District. The table below summarizes the key hydrological and operational parameters confirmed by available records.

The integration of the Daraundi A station into the local grid relies on the consistent flow of the Daraundi River. The confluence with the Marshyangdi River marks the downstream boundary of the immediate hydrological influence of the Daraundi watercourse. This geographical context is essential for understanding the plant's role in the regional energy infrastructure of Nepal. The 6 MW output contributes to the local power supply, leveraging the natural hydrological cycle of the Gorkha District. The run-of-river technology choice reflects the specific geographical constraints and opportunities presented by the Daraundi River's path through the district.

Construction History

The development of the Daraundi A Hydropower Plant involved a structured progression from initial feasibility assessments to final commissioning, characterized by specific engineering and environmental challenges. The project's early stages were defined by comprehensive feasibility studies conducted by Nil Tara Pvt. Ltd. and Orient Consult Pvt. Ltd. These foundational studies were critical in evaluating the hydrological potential of the Daraundi River in the Gorkha District of Nepal, establishing the technical viability of a 6 MW run-of-river configuration. The selection of these consulting firms ensured that the plant's design aligned with the specific topographical and flow characteristics of the river, setting the stage for subsequent construction phases.

Construction and Seismic Challenges

Construction activities officially commenced in 2013, with Kalika Construction taking the lead role as the primary contractor. This phase marked the transition from paper-based engineering to physical infrastructure development along the riverbank. The timeline of the construction was significantly influenced by external geological events, most notably the series of earthquakes that affected the region. These seismic activities introduced notable delays to the project schedule, requiring adjustments to construction methodologies and quality control measures to ensure the structural integrity of the hydropower facilities. The resilience of the construction team and the adaptability of the project management were tested during this period, as work had to be carefully coordinated amidst the shaking ground and potential landslides common in the Gorkha District.

Commissioning and Operational Status

Despite the interruptions caused by the earthquakes, the project remained on track for a relatively swift completion. The plant was successfully commissioned in 2016, marking the official start of its operational life. Upon commissioning, the facility began contributing 6 MW of capacity to the regional energy grid, fulfilling the initial projections set during the feasibility studies by Nil Tara Pvt. Ltd. and Orient Consult Pvt. Ltd. The operational status of the plant has remained stable since its inauguration, managed by the operator Daraundi Kalika Hydro. The successful completion of the Daraundi A Hydropower Plant serves as a testament to the effective management of construction risks in Nepal's hydroelectric sector, demonstrating how strategic planning and adaptive construction practices can overcome significant environmental hurdles to deliver reliable renewable energy infrastructure.
