Creation of United Energy System, 1930 - 1980

Creation of power supply systems and their consolidation for parallel work was in progress from the first years of electric power industry existence. State plan of Russia Electrification (GOELRO) involved building of 30 power plants and their consolidation for parallel work on the basis of the united electric network.

In 1945 Center Operational Dispatch Management was organized, presiding parallel work of the Moscow, Gorki, Ivanovo and Yaroslavl power supply systems.

In first half of the sixties mass building of large condensation CHPPs with blocks of 150-200-300 MW was developed. Electric networks of the European part of the country have considerably amplified. Parallel work of Urals Mountains, mid-Volga and the Center Electronic Systems Divisions has demanded their modes dispatching coordination.

In 1966 on intersystem communications of 330 kW the Northwest Electronic Systems Division and was connected for parallel work, by this time the Northwest, mid-Volga, the North Caucasus, Transcaucasia, Siberia and Central Asia Operational Dispatch Management were organized and functioned. Conditions for the formation of the country's United Power Grid were created. For the centralized management of its functioning and development in 1969 on a basis of previously was created.

For the first time in the world a three-level centralized dispatching management was organized: the Central Dispatching Management of the USSR United Power Grid - Operational Dispatch Management of Electronic Systems Divisions - the dispatching centers of power supply systems. Connection for parallel work of separately working power pool systems was one of the major problems of the United Power Grid creation. In order to solve this problem it was necessary to create the formation concept of the basic network of the United Power Grid and dispatch technological management of normal and emergency modes with attraction of data transmission and processing facilities and computing techniques. Creation of the automated system of the USSR United Power Grid dispatching management, Operational Dispatch Management control units building and their equipment with modern technical facilities became the prime Central Dispatching Management's problem. Dispatch units now were equipped with computer facilities of technological information display. Dispatcher' potential on modes management had considerably increased.

In 1976 the dispatch unit with the newest on that time computing techniques, telemechanics and communications was put in operation. By this time Central Dispatching Management was made up by with high-skilled experts with big engineering experience and represented the branch's brain centre in solution of the major management and development problems of the country's United Power Grid.

→ Creation and formation of TGC-2 capacities

In 1930 the first launch of the Central power plant in Kostroma region was made. This plant was the first among peat-burning power plants where run-around system of hydraulic ash removal was mastered.

In 1934 the station had received the name the Kostroma CHPP-1. The Yaroslavl power supply system were created on January, 2nd, 1934 when by order # 38 of Basic Industry People's Commissariat on the basis of Yaroslavl State District Power Plant and electric systems of the Yaroslavl region "Yaroslavl Power Industrial Complex" was formed. Later by the decision of USSR Soviet d/d November, 9th, 1939 of CHPP of Rubber-Asbestos concern was consigned to the Yaroslavl power supply system, and " Yaroslavl Power Industrial Complex " was renamed into district power department "Yarenergo". The first in Yaroslavl combined CHPP CHPP-1 was launched on July, 4th, 1934

February, 13th, 1936 in the Tver region by the order of the heavy industry People's Commissariat "Kalinisky Power concern" was organized, it consisted of: CHPP-1, Hydro-Electric Power Plant -2, Hydro-Electric Power Plant-3, and also the "Electric networks" and "Power sale" enterprises. The general capacity of power stations reached 19 MW, with electric networks extension of 60 km. Development of a power supply system in Tver region had begun on this day. Power stations in Vichniy Volochek, Bezhetsk, Kuvshinovo and Kalininsky CHPP -3 were constructed.

In 1937 the building of Vologda peat-burning CHPP with the capacity of 34 MW, had begun.

1938 - the Kostroma city power plant, which was in operation for about 25 years at the moment, was transformed into the electric networks enterprise (city networks) of city municipal services. The first turbo generator and 2 coppers of the Tver CHPP-4 were installed in 1940. But the launch of power plant was cancelled due to the beginning of World War II. The equipment was dismantled and taken away to east areas. The building process was resumed in 1946, and the launch took place in December, 1949.

After collectivization (1930-1941), on the Novgorod region territory the building of small heat, diesel and hydro stations, and also supply substations and power supply lines with voltage of 110 kW was proceeded by the enterprises, the organizations and collective farms.

March, 26th, 1941 the first units on Severodvinsk CHPP in the Arkhangelsk region were put in operation. During 1941 the United Dispatching Department of Verhnevolzhsky power supply systems - Gorki, Ivanovo and Yaroslavl was organized.

March, 2nd, 1941 at 00:48 the Severodvinsk CHPP-1 turbo generator of the Arkhangelsk region hooked up to the network and generated its first kW/hour of the electric power. The Tver CHPP-1, founded in 1912, was repeatedly reconstructed and extended during its existence. After Tver liberation from fascists the restored power plant was set to work in 1942. Creation of central heat supply system in Yaroslavl had been begun in 1943. Nowadays heat capacities of the Yaroslavl CHPPs, Teninsky boiler-house and Yaroslavl State District Power Plant, transferred in a mode of a boiler-house (nowadays - the Lyapinsky boiler-house which is a part of CHPP-2) provide city's apartment houses with 79 % of heat.

In 1944 decision of USSR Council of Ministers the independent Novgorod region was organized. Since 1945 the office of "Novgorod Rural Electrical Building" which was engaged in building of heat and hydroelectric power plants, power supply lines with voltage of 110 kW, regional and consumer substations, electric engines installation, installation of wirework in industrial and residential premises becomes the basic contractor of Novgorod region electrification. And still the destructions caused by war, to the objects of power industry were so magnificent, that their restoration in the necessary volume had basically begun only in the end of forties. On the Novgorod region territory the power supply questions were handled by"SelEnergo" department and the 6th high-voltage area of Leningrad High-Voltage Network. 1948 through 1955 six substations with 20 Megavolt ampere transformers were restored, in 1959 Power Supply Lines with - 110 kW Novgorod - Staraya Russa were put up in operation by trust "Sevzapelectrostroy". By the order of the State Committee of USSR power industry and electrification chairman on July, 11th, 1964 "SelEnergo" department and the 6th area of Leningrad High-Voltage Network were united and on their base in structure of "Lenenergo" the self-supporting enterprise "Novgorod Electric Networks" was created.

The region power supply system began to develop on a way of the centralized electro supply, a number of small plants were dismantled and preservation and this process remained later.

The CHPP which construction started in 1964 became one of the largest power objects in the Novgorod region, and already in 1968 turbo and boiler units # 1 were put in operation. Two years later the building of CHPP 20 was completely finished and plant reached the designed capacity of 190 megawatt. In 1945 Moscow, Gorki, Ivanovo and Yaroslavl power supply systems had entered the Center Electric power pool with unified dispatch management.

In 1945 in the Vologda region specialized organizations of "SelElectro" were created, area electrification proceeded in wider scales.

November, 30th 1953 civil-engineering design of the first stage of Vologda CHPP was confirmed. In the project the four steam boiler BKZ-50-39F with productivity of 50 steam tons per hour and two turbine units of CHSSR Brnensky factory with turbo generators "S koda 4H-5674/2" 12 Megawatt each were accepted to install. Launch of steam boiler # 1 and turbine-generator # 1 took place in I quarter (April) 1955, steam boiler # 2 - in 1955, steam boiler # 3 and turbine-generator # 2 - in 1956, steam boiler # 4 - in 1959£. CHPPs, nowadays included in PJSC "YarEnergo", were built almost simultaneously with erection of region's largest industrial enterprises first of all in order to satisfy their energy requirements. In order to provide Yaroslavl tire factory the established capacity of CHPP -1 which in 1959 reached 123 megawatt, was increased. In order to provide Yaroslavl motor factory in December, 1956 CHPP -2 was launched capacity of which has reached 220 Megawatt by 1971. In order to provide energy to the Yaroslavl petroleum processing plant on October, 10th, 1961 CHPP -3 was put into operation, its capacity by 1970 was increased up to 320 Megawatt. In 1961 power supply of the Vologda region was transferred under "YarEnergo" control. As a matter of fact during next two decades basic generating capacities and the electro network enterprises of the Vologda power supply system were created by the Company's resources. 1961 - to provide primary development of power industry in Kostroma region, RSFSR Cabinet Council on January, 30th formed regional power management "KostromaEnergo" as a part of Kostroma Council of National Economy. A.A.Voronov was appointed as administrator of the power supply system.

October, 1st, 1963 the Vologda high-voltage electric networks were included in "Yarenergo". Since April, 1st, 1964 the enterprises of electric systems with submission to "Yarenergo" were organized in Vologda and Cherepovets.

Before the connection to the United Power Grid in 1965 the Vologda CHPP was a single source of city's electric power within ten years. In 1965 CHPP was included in parallel work with United Power Grid, work reliability and stability of heat and power of consumers increased. On February, 1st, 1965 the Vologda CHPP was included in the Yaroslavl regional power management "YarEnergo" Glavsevzapadenergo of the Department of the USSR power industry and electrification as "Vologda CHPP # 4".

‚ 1965 in Kostroma region in order to cover the heat load of the Shari city and requirements of Sharinsky wood-using complex the Sharinsky power plant was constructed. In 1966 "Scheme of Vologda heat supply for 1970-75" was developed and according to it on the Vologda CHPP installation of steam boiler # 6 of BKZ-75-39F types with the capacity of 75 tons of steam per hour and a turbine unit # 3 with turbo generator ’2-12-2 with the capacity of 12 Megawatt begun in 1969. CHPP expansion under this project was finished in 1972, total electric capacity increased up to 36 Megawatt, steam capacity - up to 350 tons of steam per hour. Further the increase of heat capacity was reached by the building of a hot water boiler-house by "Electrotechmash" factory with the subsequent transfer of CHPP.

In 1969 on the western suburb of Severodvinsk city the first stage of city substation with voltage of 110/35/10 kW with the transformer 16 Megavolt ampere was launched. In 1970 the second stage, similar to the first one was launched.

In 1970 a very important event for the region took place: the Arkhangelsk city CHPP was launched on September, 28th - the first block with the capacity of 60 Megawatt was put into operation.

In 1970 electrification of Kostroma area was finished. In all regions the new scheme of electro supply operates with high economic efficiency.

In 1974 - According to the accepted general scheme of Kostroma district heat supply CHPP-2 was launched on December, 31st. Kostroma CHPP -2: nowadays with established electric capacity of 170 Megawatt , established heat capacity - 811 GCal/hour, turbine generators -2, hot water boilers-5, power boilers -4 (BKZ-210). In 1973 the first turbo generator of Kalininsky CHPP -3 (Tver region) with the capacity of 60 Megawatt was launched, and the second (capacity of 110Megawatt) - in 1976.

December, 1976 the Severodvinsk CHPP -2 was launched in the Arkhangelsk region.

In 1979 on the Vologda CHPP the hot water boiler # 1 with the capacity of 100 GCal/hour was put into operation, in 1980 - hot water boiler # 2 of KVGM-100 type.
