Overview
EL5-Energo is the supplied brand name for the Russian electricity-generation business covered by the canonical Wikipedia subject Enel Russia. The company was established as OGK-5 on 27 October 2004 during the reorganization of RAO UES, the former integrated Russian electricity utility. It was created as a generation company rather than as a nationwide electricity distributor, with its assets concentrated in large thermal power stations and later supplemented by renewable-energy projects. The company’s ownership structure changed materially during its early public-company history. It completed an initial public offering in October 2006, issuing 5.1 billion shares for an aggregate value reported in the reference material as US$459 million. Enel acquired a 29.99% interest in June 2007 from RAO UES, increased that holding to 37.15% in October 2007, and subsequently raised it to a majority position. The company adopted the name Enel OGK-5 in July 2009 and was registered as Enel Russia in August 2014. Its legal form changed from an open joint-stock company to a public joint-stock company in June 2015. The generation portfolio described in the reference material includes Konakovskaya GRES in Tver Region, Nevinnomysskaya GRES in Stavropol Krai, and Sredneuralskaya GRES in the Sverdlovsk area. These facilities primarily use natural gas, with oil identified as a backup fuel at the relevant stations, and supply both electricity and heat. The company’s stated gross installed capacity was 5,739.9 MW for electricity generation and 2,032 Gcal/h for heat generation. Its generation assets therefore serve both wholesale electricity needs and regional district-heating systems. Renewable generation became an additional strategic area. In 2017, the company won tenders for a 201 MW wind farm in Murmansk Region and a 90 MW wind farm near Azov in Rostov Region. Construction of the Azovskaya project formally began in May 2019, while construction of the 201 MW Kolskaya wind farm began in September 2019. The reference describes Kolskaya as the largest renewable project in the Arctic Circle. In 2020, the company also signed an agreement to expand renewable-energy development in Tatarstan in cooperation with Russia’s Ministry of Industry and Trade. The portfolio was reshaped when Enel Russia sold the 3,800 MW Reftinskaya GRES coal-fired plant to Kuzbassenergo. The transaction was announced in 2019 and completed on 1 July 2020. This disposal removed the company’s largest coal-fired facility and left a portfolio centered on gas-fired thermal generation, combined heat and power, and developing wind assets. The supplied materials do not establish the company’s current legal status, ownership after the referenced period, or whether all operations continue under the EL5-Energo name; those points require verification against more recent corporate sources.
History
Enel Russia originated in the restructuring of Russia's electricity industry following the breakup of RAO UES. The company was incorporated as OGK-5 on 27 October 2004, one of the wholesale generating companies created to separate generation from the former unified electricity system. It was registered in Yekaterinburg, while its headquarters were located in Moscow. OGK-5 entered the public capital markets in October 2006 through an initial public offering. Enel became the decisive strategic investor in 2007, purchasing 29.99% of the shares previously held by RAO UES in June. It raised its holding to 37.15% in October and later increased it to approximately 56.43%, giving the Italian group majority control. The company was renamed Enel OGK-5 in July 2009 and formally registered as Enel Russia in August 2014. On 25 June 2015, its legal designation changed from Open Joint Stock Company Enel Russia to Public Joint Stock Company Enel Russia. The operating portfolio was built around three large gas-fired thermal stations. Konakovskaya GRES, near Konakovo in Tver Region, had 2,520 MW of installed electrical capacity and supplied electricity and heat to the region. Nevinnomysskaya GRES in Stavropol Krai had 1,551.4 MW of electrical capacity and 585 Gcal/h of heat capacity. Sredneuralskaya GRES in Sverdlovsk Oblast had 1,578.5 MW of electrical capacity and 1,327 Gcal/h of heat capacity. Both Nevinnomysskaya and Sredneuralskaya benefited from new combined-cycle gas-turbine units commissioned in 2011. The plants used natural gas as their primary fuel, with oil available as a backup. For a period, Enel Russia also owned Reftinskaya GRES, a 3,800 MW coal-fired station and its largest coal asset. Enel agreed to sell the plant to Kuzbassenergo in 2019, and ownership transferred on 1 July 2020. The sale was consistent with a portfolio direction focused on gas-fired generation and a greater role for renewables. Wind power became a major development theme. In June 2017, Enel Russia won tenders for a 201 MW wind farm in Murmansk Region and a 90 MW facility near Azov in Rostov Region. Construction of Azovskaya began with a groundbreaking ceremony on 23 May 2019. Construction of the 201 MW Kola wind farm started on 19 September 2019; the project was described in the reference material as the largest renewable-energy project in the Arctic Circle. In 2020, Enel Russia also reached an agreement with Russia's Ministry of Industry and Trade to expand renewable development in Tatarstan. The company's reported operating scale before Enel's departure included approximately 5,739.9 MW of gross electrical-generation capacity and 2,032 Gcal/h of heat capacity. Its business model combined wholesale electricity sales with heat generation and renewable-capacity development. Enel announced its withdrawal from Russia in 2022 and sold its controlling stake. The supplied sources do not provide enough post-transaction information to determine whether the legal entity continued under the same name, was renamed, or remained listed, so its current status is left unresolved.

Products and positioning
A regional Russian electricity generator combining large gas-fired thermal plants, heat production, and developing wind-power assets.
Electricity generation
Gas-fired electricity
Electricity generated primarily from natural gas at Konakovskaya GRES, Nevinnomysskaya GRES, and Sredneuralskaya GRES. The portfolio included conventional steam-generation assets and newer combined-cycle gas-turbine units designed to improve efficiency.
Heat generation
District and industrial heat
Thermal energy supplied by the company's combined heat-and-power and thermal stations to nearby cities and industrial users. Heat production was an important secondary output of the conventional generation portfolio.
Renewable electricity · 2017
Wind-generated electricity
Renewable generation developed through the Azovskaya and Kola wind projects and related regional development initiatives. The projects represented Enel Russia's expansion beyond its gas-centered thermal base.
