Engineering and Technical Specifications

The Hanabanilla Dam is constructed as an embankment dam, a structural design chosen to harness the flow of the Hanabanilla River. Located near the village of El Salto del Hanabanilla in Villa Clara Province, Cuba, the infrastructure serves a dual primary purpose: providing essential water resources for irrigation and municipal uses, and generating hydroelectric power for the regional grid.

Reservoir Capacity

The reservoir created by the dam plays a critical role in water management in Villa Clara Province. The storage capacity is substantial, allowing for significant retention of water during peak flow seasons to support downstream agricultural needs and municipal supply systems.

Parameter Value
Reservoir Volume 286000000 m3 (232000 acre-ft)

This volume of 286000000 m3, equivalent to 232000 acre-ft, represents the total storage capability of the Hanabanilla reservoir. The embankment structure is designed to withstand the hydrostatic pressure exerted by this volume of water, ensuring stability for the surrounding terrain and the downstream communities relying on regulated discharge.

Power Station and Installed Capacity

The hydroelectric power station is situated near the base of the dam, optimizing the hydraulic head for power generation. The facility converts the potential energy of the stored water into electrical energy, contributing to Cuba's renewable energy mix. The plant has been operational since its commissioning in 1961.

Parameter Value
Installed Capacity 43 MW

The installed capacity of the Hanabanilla hydroelectric powerplant is 43 MW. This output is generated through turbines driven by the flow of water from the reservoir through the penstocks located at the dam's base. The 43 MW capacity allows the facility to provide a steady baseload or peaking power depending on the water availability and the demand on the local grid in Villa Clara Province. The integration of the power station at the base of the embankment dam ensures efficient energy extraction from the Hanabanilla River's flow.

Construction History and Timeline

The construction of the Hanabanilla Dam represents a significant infrastructural development in Villa Clara Province, Cuba, designed to serve dual purposes of hydroelectric power generation and water resource management. The project was initiated in 1958, marking the beginning of a major engineering effort along the Hanabanilla River. This period of construction preceded the formal commissioning of the facility, establishing the foundational embankment structures necessary to regulate water flow near the village of El Salto del Hanabanilla.

By 1961, the dam was officially commissioned, bringing the hydroelectric powerplant into operational status. This milestone established the facility’s primary role in providing water for irrigation and municipal uses while generating 43 MW of capacity. The completion of the main dam structure in 1961 allowed for the subsequent integration of the power station, which was commissioned in 1963. This phased approach ensured that the water retention capabilities were fully established before the full electrical output was realized, optimizing the efficiency of the hydroelectric system.

Decades after its initial completion, the Hanabanilla Dam underwent a significant rehabilitation phase starting in 2014. This modernization effort aimed to maintain the operational integrity of the embankment dam and ensure continued reliability in power generation and water supply for the region. The timeline of the Hanabanilla Dam’s development reflects a long-term commitment to energy infrastructure in Cuba, with key milestones spanning from the initial construction start in 1958 through the power station commissioning in 1963 and the later rehabilitation efforts in 2014.

Why is Hanabanilla Dam significant for Cuba?

The Hanabanilla Dam holds a pivotal position in Cuba’s energy and water infrastructure landscape as the island’s largest hydroelectric power station. With an installed capacity of 43 MW, the facility represents a critical component of the national grid, particularly for the central region. Its operational status since its commissioning in 1961 underscores its long-standing role in providing renewable energy to the country, reducing reliance on thermal generation during peak water flow periods.

Hydroelectric Leadership in Villa Clara

Located in Villa Clara Province, the dam is situated on the Hanabanilla River near the village of El Salto del Hanabanilla. This strategic placement allows the facility to harness the water resources of the region effectively. As the largest hydroelectric plant in Cuba, the Hanabanilla Dam serves as a benchmark for hydro-power generation on the island. The 43 MW output is significant for a national grid that has historically depended heavily on imported fuels, offering a stable, domestic source of electricity.
