Akköy Dam

Akköy Dam is a general name given to two separate dam projects located in different regions of Türkiye. One is the Akköy Dam constructed in Kayseri province for irrigation purposes, while the other is a dam complex linked to the Akköy I and Akköy II Hydroelectric Power Plants (HPPs) built in Gümüşhane province for energy generation.

These structures referred to as Akköy Dam are important components of Türkiye’s water resource management strategy and hold significant importance for both agricultural irrigation and renewable energy production. The dam in Kayseri serves agricultural irrigation, while the dams in Gümüşhane are focused on high-capacity hydroelectric power generation.

The Akköy Dam, located in the Yeşilhisar district of Kayseri province on the Asarcık Stream, was completed between 1964 and 1967 as an irrigation dam. It was developed to support agricultural activities in the region by ensuring efficient use of water resources for irrigating farmland.

• Location: Kayseri Province, Yeşilhisar District, Asarcık Stream.
• Construction Year: 1964–1967.
• Purpose: Agricultural irrigation.
• Dam Type: Rockfill.
• Dam Volume: 463,000 m³.
• Height: 41.50 metres from the riverbed.
• Reservoir Volume: 7.50 hm³.
• Reservoir Area: 0.79 km².
• Irrigated Area: 926 hectares.

This dam plays a crucial role in meeting the irrigation needs of farmlands in Yeşilhisar district, particularly during dry periods. The water supplied by the dam enhances regional agricultural productivity and supports sustainable farming practices.

The name Akköy Dam is also used in reference to the Akköy I and Akköy II Hydroelectric Power Plants in Gümüşhane province. These plants are major projects that generate electricity using dams built on the Harşit River and its tributaries. Akköy II HPP, one of Türkiye’s highest-head hydroelectric plants, is ranked among the top 10 worldwide in terms of head height.

Akköy I HPP is located in the Kürtün district of Gümüşhane province on the Harşit Çayı stream. This plant is one of the key projects developed to meet Türkiye’s energy demands.

• Location: Gümüşhane Province, Kürtün District, Harşit Çayı.
• Construction Year: 2008.
• Dam Type: Roller-Compacted Concrete (RCC).
• Dam Height: 54 metres.
• Energy Tunnel: 12.5 km long.
• Installed Capacity: 103.5 MW (three Francis turbines of 34.5 MW each).
• Annual Generation Capacity: 320 GWh.
• Commercial Operation Dates: 18 September 2008 (first two units), 26 November 2008 (third unit).

Thanks to its high head capacity, this plant achieves high-efficiency energy generation and plays a significant role in meeting Türkiye’s energy needs.

Akköy II HPP is a large-scale hydroelectric project located in Gümüşhane alongside Akköy I HPP, comprising three dams that operate together to produce substantial amounts of electricity. The Aladereçam, Gökçebel, and Yaşmaklı dams function in unison to enable large-scale energy generation.

• Location: Karaovacık Stream, Gümüşhane.
• Talveg Elevation: 1,797 m.
• Storage Capacity: 13.934 million m³.
• HPP Capacity: 7.56 MW.

• Location: Gelavara Stream, Gümüşhane.
• Crest Elevation: 1,630 m.
• Height: 144 m (rockfill with concrete facing).
• Storage Capacity: 94.777 million m³.

• Location: Gavraz Stream, Gümüşhane.
• Crest Elevation: 1,630 m.
• Height: 118 m (concrete gravity dam).
• Storage Capacity: 19.707 million m³.

• Total Installed Capacity: 233.57 MW (two Pelton turbines of 116.79 MW each).
• Generator Capacity: 2 x 135 MVA.
• Annual Generation Capacity: 872.5 GWh.
• Maximum Head: 1,220 metres (highest in Türkiye, among the top 10 globally).
• Commercial Operation Dates: 7 June 2012 (first unit), 5 July 2012 (second unit).

Akköy II HPP is one of Türkiye’s most efficient hydroelectric plants due to its high head capacity and holds significant importance for the effective utilization of renewable energy sources.

The name Akköy Dam encompasses two distinct projects in Türkiye, one for irrigation and the other for energy production.

• Akköy Dam in Kayseri, constructed in the 1960s, is used to irrigate agricultural lands in the region.
• Akköy I and Akköy II HPP projects in Gümüşhane, among Türkiye’s largest hydroelectric facilities, make a significant contribution to the country’s energy supply.

These two separate dam complexes play a vital role in Türkiye’s water and energy management policies, serving as key projects that support the sustainable use of water resources and the production of renewable energy.
