By 1969 two PT-100-130 type turbines of type "T-100-130" of the unit 2 started to operate, increasing heat distribution to 560 kcal/h (650 MW) and overall capacity to up to 300 MW. In 1974, the first block was combined with a second in close proximity, which had a capacity of 810 MW in four condensing power-generating units. The new Hrazdan State Regional Power Plant (SRPP) became, with 1110 MW total power, the most powerful power plant of

It closes for two to three months each year for maintenance and refueling, and HTPP steps in to meet consumer needs. The HTPP has also a big role in the export of electricity.

120-metre (390 ft) cooling towers. Natural traction brings cooling air to the four towers. Heat loss is minimized by the use of chemically desalinated water in the closed circuit of cooling, which enables the usage of mixing condensers instead of surface condensers. This also reduces maintenance.
533:
The HTPP is considered as one of the most environmentally friendly non-nuclear TPPs in
Armenia. In the aim of excluding any possibility of water loss connected with evaporation, specially devised cooling system is used for cooling condensers in the four blocks. The cooling system, which was developed

of Russia. In July 2009, all stocks minus one share were acquired by the RUssian state-owned holding company
Rosneftegaz. In May 2011, all shares were bought by Inter RAO UES. In 2015, Inter RAO UES sold the Hrazdan Energy Company to Cyprus-registered Liormand Holdings Limited, a part of Tashir

At the time when the coolers were being constructed, aluminum radiators were used as heat exchangers to cool down the circulating water which heats up in the condensers. The key part which enables the usage of resources is the placement of the radiators, which are located along the edge of the

Total of $ 465.2 million were spent for the construction and modernization of fifth energy block. For the construction of
Hrazdan-5 different types of turbines were used, which work with steam and gas. The use of this technology enables the block to have a power of 480 MW. The new

Five oil and gas boilers are used to power four co-generation turbines, two of model PT-50-130/7 and two of model T-100-130. T-100-130 turbines have a capacity twice as big as of model PT-50-130/7, 100 MW of capacity. The plant boasts five evaporative cooling towers and six feed pumps.
529:
The block part of the power plant consists of four power generator units, model TFM-104C gas and oil boilers with capacity of 670 t/h. TDC-250000/220 transformers connect two turbo-generators (TGV-200-2MUZ (Block No. 1) and TGV-200M (Blocks No. 2, 3, 4)) of 15.75 kV of voltage to

construction, which has a vital strategic importance for
Armenia. Particularly, according to the agreement, the energy produced in Hrazdan Thermal Power Plant's 5th energy block is exported to Iranian energy system and serves as a means of paying for natural gas imported from Iran.

During its peak in the 1980s, the HTPP generated 6.85 TWh annually, with 7,300 hours (83%) clocked at total capacity. Between 1963 and the end of 2004, it produced 143 TWh electricity, but 12.3 Gcal/h energy in the form of heat.
549:
Since 1993, the HTTP has used natural gas as its primary fuel, relying on oil as a reserve, a reversal of its earlier pattern. A gas distributing station and gas grid carry gas to gas control points throughout the plant.
