Substations

Alstom has delivered upgraded complex air-insulated substations to Armenia's state-owned company CJSC High Voltage Electrical Networks (CJSC HVEN) - and the Ministry of Energy & Natural Resources in Gyumri, north-west of Armenia.

The company secured a complete rehabilitation turnkey project in 2011, covering the engineering,, design, production and delivery, construction, assembly and commissioning of the three modules of 220kV, 110kV and 10kV open-air substations furnished in the 1970s.

Apart from interconnecting Armenia's existing 220kV stations, the 220kV facility also through another substation is directly connected to the 400MW nuclear power plant in Metsamor, which covers approximately 40% of the country's energy demand.

Funded by the KfW, the €12m project aims to improve national grid stability, in addition to the economic and secure supply of power.

CJSC HVEN operates the transmission grid in Armenia, managing a total of thirteen 220kV stations.

The completion of the new 220kV facility establishes a connection to the neighbouring countries for the exchange of electrical energy.

Meanwhile, the 110 kV substation supplies energy to the Schirak province (area surrounding Gyumri), and the 10kV facility is furthermore of local significance for the supply of energy to the city of Gyumri and the surrounding towns and villages.

"The €12m project aims to improve national grid stability, in addition to the economic and secure supply of power."

Alstom Grid project manager Artur Chamyan said the project execution lasted 28 months, with tight scheduling given the prevailing weather conditions in winter - the city of Gyumri is at an altitude of 1,600m above sea level.

"Thanks to the collaborative professionalism of our project and on-site teams, with support and cooperation from our customer, we were able to deliver in a timely manner and make an important contribution to Armenia's economic development," Chamyan said.

Alstom Grid has managed the project and the site management took place in the Armenian cities of Gyumri and Yerevan.

The 110kV power switchgears were supplied by the Alstom plant in Kassel, which is among the world's largest production sites for high-voltage technology and is the centre of excellence for high-voltage switching devices from 36kV to 170kV.
