6 FAQs about [Armenia energy harvesting systems]
How does Armenia generate electricity?
Most of the rest of Armenia's electricity is generated by the natural gas-fired thermal power plants in Yerevan (completed in 2010) and Hrazdan. Upon gaining independence, Armenia signed the European Energy Charter in December 1991, the charter is now known as the Energy Charter Treaty which promotes integration of global energy markets.
Why does Armenia need a single energy supplier?
Armenia relies on imports of natural gas and oil for most of its energy needs, which exposes it to supply risks and dependence on a single supplier. As the government considers energy security and the development of indigenous sources to be of prime importance for the energy sector, renewables and efficiency measures are key areas.
How has Armenia restructured its energy sector?
Prompted by a severe electricity supply crisis in the mid-1990s, Armenia has revamped its energy sector over the past 20 years. Parts of the sector have been privatised, some companies have been restructured, most households now have access to gas, and cost-reflective tariffs have been introduced.
Does Armenia use natural gas?
Natural gas represents a large portion of total energy consumption in Armenia, accounting for 50% and is the primary means of winter heating in the country.
Does Armenia trade electricity with Georgia?
Armenia also trades electricity with Georgia, though volumes are low since the countries’ networks are not synchronised. Energy interconnections with Azerbaijan and Türkiye are currently inactive for political reasons. Prompted by a severe electricity supply crisis in the mid-1990s, Armenia has revamped its energy sector over the past 20 years.
How much energy does Armenia need?
It has been an observer to the Energy Community since 2011 and a member of the Eastern Partnership since 2009. Although Armenia’s energy demand averages more than 3 Mtoe (3.59 Mtoe in 2020) and the country does not produce any fossil fuels, it manages to cover 27% of energy demand with domestic energy production.
