Foundation and early years
The Joint Stock Company of Electric Lighting was founded in 1886 by Carl Siemens, a Saint Petersburg merchant of the First Guild who was the Head of the Siemens & Halske Representative Office.
The Company was founded in Saint Petersburg; however, at its very first Board of Directors’ meeting, a proposal was made to prepare grounds for Company operations in Moscow. At the end of 1888, the Company successfully completed the construction of the first centralized power plant. In 1912, the Company started building the world’s first peat-fired district power plant in the Bogorodsky District. In April 1913, a new company, the Moscow Joint Stock Company Elektroperedacha, was founded in order to utilize the capacity generated by the new station. The joint stock companies Electric Lighting 1886 Company and Elektroperedacha operated successfully until October 1917. After the October Revolution, those companies were nationalized and ceased operations under their previous managers in December 1917.
Development in the Soviet Union
The management of state power stations was delegated to the Power Department of the Supreme Council of Public Property.
At the same time, in December 1917, Ivan Radchenko and Aleksandr Vinter proposed to develop the Moscow power industry further. These proposals became the basis for the first State Plan for the Electrification of the whole country, GOELRO. Pursuant to the GOELRO Plan, several stations were built in the Moscow Region, namely Kashirskaya SDPP (now SDPP-4), Shaturskaya SDPP (now SDPP-5), Krasnopresnenskaya TPP, TPP-6 and TPP-8. One of the key events in this period was the completion of Russia’s first 110 kV voltage power line between Kashira and Moscow, as well as a two-circuit ring of power lines and transformers around Moscow with a voltage of 115 kV
Operations during the World War IIThe start of World War II put the development of the power system on hold.
Part of the equipment was destroyed, another part was evacuated and the total capacity of Mosenergo dropped twofold. Nevertheless, Moscow power engineers managed to maintain a continuous supply of power to the city’s defense facilities; they constructed high-voltage obstacles to defend against enemy troops and assembled power-generating trains for the liberated regions of the country. The restoration of the power industry started immediately after the successful counter-offensive campaign of the Soviet Army in the winter of 1941–1942. As early as 1945, Mosenergo had already managed to achieve a pre-war level of installed capacity.
Technical upgrading and transformation to JSK
In 1946, Mosenergo began to utilize a new type of fuel: TPP-1 started burning natural gas.
Transforming to JSK, reform period
In the 1990s, Mosenergo continued to build new generating capacities. In 1992, water-heating boilers, in 1996–1998, two power units were put into operation at Severnaya CHPP (today — CHP-27).
In April 2005, during the reform of the Russian Federation Government, Mosenergo, the Russian largest vertically integrated regional energy company at the time, was divided into 14 separate companies by type of business: generating, network, repair, sales, etc.
Mosenergo retained its generating assets, uniting 32 branches, including 17 thermal power plants with a total installed capacity of 10,600 MW and a heat capacity of 39,000 MW.In 2005, Mosenergo grew and started the implementation of the Program for Development and Technical Upgrading, including the planning, construction and commissioning of new generating facilities on the sites of operational power plants in energy-deficient regions and heat and electricity demand nodes with developed infrastructure.
In 2007, a strategic investor — Gazprom PJSC — came to Mosenergo's management. By 2008, the gas holding company has accumulated more than 50% of the Company's shares.
All of these investments were made on the basis of Power Delivery Contract, which guarantees the return on investment.
On May 20, 2015, the extraordinary general shareholder meeting of Mosenergo PJSC decided to transfer powers of the Company’s sole executive body to the managment organization: Gazprom Energoholding LLC. This decision was made to improve the management efficiency, avoid duplication of functions, and cut administrative expenses and other costs.Nowadays the Company works on on operational efficiency and asset quality improvement and also looks for new investment initiatives implementation.
In 2017 Mosenergo celebrated its 130th anniversary. Throughout its history, the company is one of the leader in the country's energy industry development.
The first energy system in Russia was laid in Moscow. Moscow power engineers took an active part in the development and practical implementation of the Russian State Electrification Plan (GOELRO). Since the 1930s, the first in the country centralized heat supply system has begun to develop in Moscow, which by the end of the 20th century became the largest in the world.
Moscow power engineers made a huge contribution to the Victory in the Great Patriotic War, providing reliable power supply to defense enterprises, departments and residential buildings. The Moscow energy system restoration in the postwar years, the new powerful power plants construction, the introduction of modern technologies — these are all important milestones in the activities of Mosenergo afteryears.
Today Mosenergo continues to develop dynamically, performing its main task on a daily basis — ensuring reliable operation of production facilities that supply electricity and heat to consumers in the Moscow region.
