[3][4] The Teploelectroproject Institute began planning the Yerevan Thermal Power Plant in 1959.

[1] However, there is a plan to rehabilitate two 50-megawatt units of the old plant to process coal from Nagorno-Karabakh.

[1][5] A gas turbine, a generator, and auxiliary equipment were supplied by Alstom.

The new plant was inaugurated by Armenian president Serzh Sargsyan on 22 April 2010.

[10] In 2015, it was announced that the Italian contractors Renco S.p.A. would build and operate a $285 million, 250 megawatt unit, with an up to 53% general coefficient of efficiency.

[11] The groundbreaking of the construction of the new unit took place on March 30, 2017 at the vicinity of the new combined-cycle plant, with the presence of President Serzh Sargsyan, the Director General of Renco Company Mr. Jovanni Rubini, and the Ambassador of Italy to Armenia Mr. Giovanni Ricciulli.

[12] The old plant, which consisted of seven units, had 550 megawatts of electrical power and 630 GCal/h of thermal capacity.

[7] The re-equipment of the operating unit of the Yerevan Thermal Power Plant is set to kick off in August 2018 as a result the plant's capacity is supposed to increase by about 7 MW to 227 MW, the specific fuel consumption will reduce from 258.1 g/kWh to 252.8 g/kWh, the efficiency of the power unit will increase by 1%, the useful generation of electricity will increase by 59.5 million kWh, which corresponds to more than 1.2 billion drams under the current tariff.

[3] Compared with the Hrazdan Thermal Power Plant, it uses half as much fuel: no more than 256 grams (9.0 oz) per kilowatt hour of electricity.
