Hrazdan TPP 1100 MW

Yerevan TPP 550 MW

Sevan-Hrazdan cascade of HPPs 550 MW

The results of asset reevaluation showed

Evolution of the Energy Sector

Replacement of the equipment in Energy Sector is required

The Energy Sector is threatened with serious equipment crisis

Equipment doesn’t comply with international standards forefficiency and environmental protection

38% of installed capacity is over 30 years old

Most TPP units have reached their design limit of operating hours

HPPs-70% of installed equipment is more than 30 years old and

-50% - more than 40 years

The Energy Security of Armenia

Energy Security - ability for the reliable energy

supply for all requirements of a person, society

and country under stable development as well as

extreme conditions. Ensuring of Energy Security is the main task and

responsibility of the State Institutions without

excepting the participation of private and public

organizations of Armenia.

Supply OptionsHydropower Potential

Untapped hydropotential is 480 MW, which would generate 1800 GWh per year

60% of this can be developed at less than USc 6 / kWhShnokh (75 MW)Megri (80 MW, on the border with Iran)Small hydro projects (75 MW)

Some good locations for pumped storage plants exist

Supply OptionsOther options

Geothermalcan be used for district heating onlyresearch and development urgently required

Windpower limited potential, but some good sites exist: Pushkin Pass, Aragaz, Sevan Lake, Sisian Pass

MiscellaneousSolar too expensiveWaste incinerator (10 MW)

Supply OptionsThermal Plant

No new thermal capacity is needed until 2007

Conversion of existing thermal units to combined cycle plant is too expensive

Best candidate plant for future

combined cycle CHP 167 MW

combined cycle 300 MW

Supply OptionsNuclear Plant

New 600 (#4) MW unit would beginning to work in 2016-2017

More expensive than gas-fired CC plant, but important in the

context of fuel diversification

New 600 (#3) MW unit would replace existing unit #2 in 2015
