8 According to the Law On Energy of the Republic of Armenia, the main principle of the Government policy in the Energy sector is the separation of functions of economic activity, state management and regulation. According to the main regulating principle, the rights of the consumers and economic interests in the energy sector are to be balanced. According to this Law, the functions of regulation were given to the Commission on Public Services. On 01 August2015 the following tariffs were established for electricity: TARIFF FOR ELECTRICITY (AMD/kWh) Groups of final consumers Unit Tariff rate, day (night), (VAT inclusive) 1 consumers using 110 kv and above connection AMD/kWh 37.28(33.28) 2 consumers using 35 kv and above connection AMD/kWh (35.78) 3 consumers using 6(10) kv connection AMD/kWh (35.78) 4 consumers using 0.38 kv connection AMD/kWh (38.78) 5 residential customers AMD/kWh (38.78))

9 Main Indicators On January 1, 2015 the total capacity of the electric energy generating plants in Armenia was 4.06 GW(e). In 2015, electricity production was 7.8 billion kwh. Table 5 shows the historical statistics of electricity production and its distribution by plant types, Table 6 - the energy related ratios. In 2015, the electricity consumption was around 2016 kwh/capita in Armenia. The electricity consumption of Yerevan city is about 34% of the total electricity consumption in Armenia.

11 NUCLEAR POWER SITUATION Historical Development and current organizational structure A decision to construct a nuclear power plant in Armenia was made by the former USSR Council of Ministers, and the appropriate decree was issued in September The technical specification to design the ANPP was developed by Teploelectroproject in 1968 and approved in August 1969 under decree N 1624 R.C. of the former USSR Ministry of Energy. More than 20 potential sites were considered for the ANPP construction, and finally a site was selected in the western part of the Ararat valley, 16 km from Turkish border, 10 km to the north-east of region centre Hoktemberyan (Armavir), and 28 km (to the west) from Yerevan. Location of the ANPP is shown in Figure 3. In accordance with that specification, the capacity of the ANPP (first stage of construction) with VVER-440 type reactors was to be MW, each unit of MW. The ANPP design life-time was specified to be 30 years. The comprehensive studies and analyses showed that seismic conditions of the ANPP site were characterized an intensity level of eight-point s according to MSK-64 scale. It was the first nuclear power plant in the USSR intended to be constructed in a region of high seismicity. The specific nature of the ANPP site - its seismicity - caused significant changes in the design of VVER-440/230, not only in construction, but also in the design of the reactor facility as a whole, and the reactor was assigned with the new identification V-270. The design of the reactor was based on the project of Unit 3 and 4 of the Novovoronezh NPP. The reactor building, auxiliary building, ventilation stack, as well as the buildings and structures containing equipment and instrumentation of safety systems or safety-related on-line systems and communications connecting these structures were assigned with a category of High Importance. They were considered to have one point more seismic resistance than that of the ANPP site. The ANPP was commissioned in 1976, achieving initial criticality for Unit 1 on 22 December 1976 and for Unit 2 on 5 January The units were put into commercial operation on 6 October, 1977 and 3 May 1980, respectively.

13 After the 1988 earthquake, although the ANPP was not damaged, the Council of Ministers of the USSR decreed to shut down the ANPP as a precautionary measure. Unit 1 was shut down on 25 February, 1989 and Unit 2 on 18 March, The units were not decommissioned, but kept in prolonged shut down condition. Apart from those which occurred during the short period of regaining independence, there have been no strong antinuclear movements in Armenia. The current sentiment of the public can be explained not by lack of awareness of the risks involved in the utilization of nuclear energy, but, in the face of the difficult economic conditions, by the considerably lower price of nuclear electricity, which outweighs its possible risks In April 1993, the Government of Armenia decided to restart Unit 2 of the ANPP in order to overcome the severe economic crisis, taking into account the lack in national energy resources. Following 6.5 years of outage, with the technical and financial help of the Russian Federation, Unit 2 of the ANPP was restarted on 5 November Unit 1 remained in a state of stand-still. According to the decision of the RA Government minutes on 27 March 2014 the works for the extension of the Armenian NPP Unit 2 design lifetime have been launched. After the execution of the work the relevant documents will be submitted to the Armenian Nuclear Regulatory Authority to receive the Unit s exploitation license for the period beginning September Following the ANPP restart, billion kwh of electric energy had been generated by 1 January, keeping to the load schedule of the Armenian power system.

14 Nuclear Power Plants: Overview The ANPP consists of two VVER-440 type nuclear power units. Both units of the ANPP with the VVER- 440 (V-270) type reactors were designed and constructed by organizations of the former Soviet Union under the supervision of the Ministry of Energy and Electrification of the USSR. The design of the first stage of the plant was developed in The chief scientific supervisor was Kurchatov Institute of Atomic Energy (Moscow). Now it is called RNC Kurchatov Institute. The chief design organization was Teploelectroproject (TEP), Gorki. Now it is called NIAEP, Nizhny Novgorod. The main reactor construction organization was OKB Gidropress, Podolsk. The Izhora Factory Leningrad Enterprise was the manufacturer of the reactors and systems. The turbines were manufactured by the Kharkov Turbine Plant (KHTP). The electric generators were supplied by the Electrosila plant of Leningrad. The building-construction work was performed by the Gidroenergostroy, Yerevan. Since 1989, Unit 1 remained in a stand-still regime. Since its restart (1995), Unit 2 of the ANPP has been in operation. Unit 2 has an installed gross capacity of MW. All the nuclear fuel necessary for the ANPP operation was delivered in the past and is currently being delivered by the TVEL Concern of Russian Federation.

17 Future Development of Nuclear Power According to the decision of the RA Government minutes on 27 March 2014 the works for the extension of the Armenian NPP Unit 2 design lifetime have been launched. After the execution of the work the relevant documents will be submitted to the Armenian Nuclear Regulatory Authority to receive the Unit s exploitation license for the period beginning September The Energy Security Ensuring Concept of the Republic of Armenia was adopted by the President of RA on 23 October 2013 according to which Armenia will continue to exploit the existing nuclear unit until the construction of the new one. Action Plan for provision the energy security concept of the republic of Armenia for was adopted by the Government Decree 836-N as of 31 July According to the action plan in 2026 should be put into operation the new nuclear power plant up to 1000 MW capacity. The document on Long-term (up to 2036) development pathways for RA energy sector has been approved by the RA government protocol decision 54-13, on 10 December Nuclear scenario of development has been once again stated. According to that document taking into account the energy consumption and the needs to ensure the energy security of the country is necessary to build the new nuclear power plant up to 600 MW capacities.
