ΜΥΗΣ AGIA

The Project

The Small Hydroelectric Power Station (MYHS) along with the artificial lake of Agia in Chania form a unified technological project from the 20th century. It was a groundbreaking achievement for its time, serving as a brilliant example of harnessing water resources and Renewable Energy Sources in Greece.

The station utilizes a 4-meter elevation difference from the artificial lake's water level. Water from the lake flows toward the MYHS, passing through a 435-meter-long earthen dam and then through a closed concrete pipeline (penstock) that is 490 meters long and 2.5 meters in diameter. From there, some of the water is directed into a small stream (tailrace channel) via a metal sluice gate, while the rest is pumped to a rooftop tank (surge tank) standing 9.2 meters high. When the tank overflows, water is forced downward with power into a separate chamber inside the building. During its fall, three pairs of open Francis-type turbines rotate, and through their horizontal shafts, they transferred motion to three electromagnets–generators, which produced alternating electric current.

The History

The Small Hydroelectric Power Station of Agia was inaugurated on July 22, 1929, by the then Prime Minister of Greece, Eleftherios Venizelos. During its operation, it provided a small but significant amount of electricity to the city of Chania. It delivered electricity at low cost, on demand (whenever needed), in an environmentally friendly way, without additional pollution.

To meet the ever-increasing electricity needs of the city and the surrounding settlements (Agia, Agrokipio, Alikianos, Varýpetro, Galatas, Kokkinos Pyrgos, Mournies, Pelekapina, Perivolia, Skoulas, Souda, Chrysopigi), the Municipality of Chania established a thermal power plant on Ypsilanton Street in 1936.

As one of the few hydroelectric plants of its time, the SHPP remained in operation until 2005. Initially, it belonged to the Municipal Lighting Company of Chania. In 1959, it was purchased by the Public Power Corporation (PPC), and later utilized by PPC Renewables S.A.

Before the founding of PPC and the beginning of the acquisition process across Greece, a total of 63 cities and settlements in Crete were supplied with electricity by 43 different companies! Most of these belonged to local olive oil or agricultural cooperatives (22), followed by community/municipal electric companies (11), and finally private companies (10).

Industrial Architecture

The Station building is a piece of industrial archaeology, embedded in the modern history of the city and in the collective memory of the society of Chania. The presence of such a pioneering project in early 20th-century Crete holds historical, technological, social, architectural, and scientific significance today.

The project is credited to the Italian Prinzivalli and the Swiss engineer Sen, in collaboration with a group of engineers from Heraklion.

The Station features modern architectural characteristics. It is generally defined by a lack of decorative elements, with its load-bearing structures clearly visible and “clean” in form. There is a distinct separation between the functional parts of the building: the generator hall, the power distribution tower, and the water tank/drop shaft. The electromechanical equipment was manufactured by the German company AEG.

The Idea

As the demand for electricity production increases, PPC moves forward with the operation of new power plants and the repurposing of small, decommissioned power stations for use by local communities. Thus, the former Small Hydroelectric Power Station (SHPP) of Agia is transformed into an Exhibition Space for Renewable Energy Sources (RES).

The goals are:

a. To raise public awareness about:

  • – the preservation of industrial heritage, local culture, and history.

  • – electricity generation using Renewable Energy Sources.

  • – topics of scientific, technological, and environmental interest.

  • – the conservation of biodiversity and the management of habitats.

b. Recreation!

The SHPP and the wider wetland of Agia are a popular destination for walkers and nature enthusiasts.

Its proximity to the city of Chania attracts a large number of both local and foreign visitors, mainly interested in the area's flora and fauna.
