The Devoll Hydropower Sh.a. ( DHP for short ) is an energy company operating in Albania with headquarters in the capital Tirana . There is an operational headquarters in Gramsh .

Corporate structure

Until 2012, the company was a joint venture between the Austrian EVN AG and the Norwegian Statkraft AS , both of which had a 50% stake in DHP. The Albanian government signed a concession agreement with the DHP with the BOOT model (Build, Own, Operate and Transfer). With this contract, DHP is obliged to plan, build and operate hydropower plants in the valley of the south-eastern Banian river Devoll . The concession agreement was ratified by the Albanian Parliament and entered into force on August 1, 2009. EVN AG left this joint venture in 2013 and Statkraft has been the sole owner of the company ever since.

With the construction of three hydropower plants on this river, the energy problem in Albania is to be counteracted. The country's own production increased by at least 20% with the commissioning of the power plants.

Project

The project consists of two or three hydropower plants along Albania's third longest river, the Devoll . The difference in altitude between 95 and 810  m is used. The total output of three power plants will amount to 280 megawatts. The two power plants built generate 729 gigawatt hours of electricity annually.

According to information from 2010, the project costs should amount to around one billion euros . After the construction of the two larger power plants, the investment was put at over 535 million euros.

Banja hydropower plant

Banja reservoir with dam

The power plant near Banja is the first project that was implemented. It is located about 17 kilometers south of Elbasan (as the crow flies) and is the lowest of the three barrages. It uses an existing coffer dam , which is 175  m above sea level. A. was increased. The power plant, equipped with two Francis turbines , uses a height difference of 80 meters. The barrier, which was built as a dam (rock embankment with an earth core), is 80 meters high. A lake area of ​​around 14 square kilometers is dammed, which extends to the city of Gramsh . The water volume is 391 million cubic meters. After a little more than three years of construction, the power plant was opened in September 2016.

Kokël hydroelectric power station

The Kokël power plant was the smallest of the three planned power plants and was supposed to use a height difference of 55 meters. It was planned to equip it with two Francis turbines as well. The approximately 50 meter high concrete and stone embankment dam would have dammed a lake area of ​​0.85 square kilometers and a water volume of around 19 million cubic meters. Kokël is about 25 kilometers south-east of Gramsh (as the crow flies).

At first they wanted to decide on the realization only after the first two power plants had been built. In 2016 the project was no longer mentioned on the Devoll Hydropower website.

Construction of the middle tier Kokël is postponed indefinitely.

Moglica hydropower plant

Construction work on the Moglica dam in summer 2017

The power plant near Moglica, also equipped with two Francis turbines, is the largest of the three plants. It uses a height difference of 300 meters. The power plant is located in a cavern about eleven kilometers downstream from the dam. This zoned dam was poured from quarry material and river gravel and provided with an asphalt inner seal. With a height of 150 meters, it was the highest dam of this type of construction in the world when it opened. A lake area of ​​7.2 square kilometers and a volume of 360 million cubic meters will be dammed. The backwater is led to the cavern power plant via a 10.7 kilometer long headrace tunnel. After an approximately 800 meter long underwater tunnel, the headwater is returned to the river or, in the case of the construction of the middle stage Kokël, to the backwater of the downstream power station.

It was originally expected that the power plant could be commissioned in 2018. The start of the tunnel boring machine for the first 7.5 kilometers headrace began in 2016. In the summer of 2019, the damming of the lake began. After less than five years of construction, the power plant went into operation in January 2020. As a result, electricity production in Albania has increased by over 15%.
