These exchanges are integral to Armenia's broader energy strategy, contributing to the plant's role in producing a quarter of the country's total electricity output.
Mechanics of the Energy Swap
The swap mechanism operates on a specific barter-like exchange rate that links natural gas volumes directly to electricity generation. The agreed-upon ratio is three kilowatt hours of electricity for each cubic meter of natural gas supplied by Iran. This fixed exchange rate provides a predictable framework for valuing the energy transferred across the border, reducing currency fluctuation risks for both operators. The Iranian natural gas is transported to Armenia through the dedicated Iran-Armenia gas pipeline, which delivers the fuel directly to the Yerevan Thermal Power Plant for combustion.
At the plant, the natural gas fuels the combined-cycle turbines, generating the precise volume of electricity required to meet the swap obligations. The resulting power is then transmitted through the Armenian grid and exported to Iran, completing the cycle. This arrangement allows Armenia to utilize Iranian gas reserves efficiently while providing Iran with a reliable source of thermal power generation capacity located near the border. The seasonal nature of the swaps suggests that the volume of exchanged energy may vary depending on peak demand periods in either country, such as winter heating loads or summer cooling peaks.
