JSC Obyedinyonny Kommunalny Operator (JSC OKO) is a Nizhny Novgorod utility company and the largest supplier of heat, hot and cold water, and wastewater services in Nizhny Novgorod. The company operates more than 1,700 km of heat networks in the Sovetsky, Sormovsky, Kanavinsky, Nizhegorodsky, Prioksky, Moskovsky, and Leninsky Districts of Nizhny Novgorod, as well as nearly 3,400 km of water supply and wastewater networks across all city districts.[5] It was registered on 22 December 2006 through the reorganization (conversion) of the municipal enterprise "Teploenergo".[3] The current name has been in use since 12 November 2025 — previously the company operated under the name JSC Teploenergo.[2] The sole founder is the municipal entity — the urban district of the city of Nizhny Novgorod.[3] Registered address: 14 Bulvar Mira, Bulvar Mira, Nizhny Novgorod.[2]

History and Reorganization

The company traces its history to the municipal enterprise Teploenergo, which was converted into a joint-stock company in December 2006.[3] In 2025, a large-scale reorganization took place: effective 1 October 2025, JSC Nizhny Novgorod Vodokanal was merged into JSC Teploenergo by way of universal succession — all rights and obligations of the vodokanal were transferred to Teploenergo.[2] On 12 November 2025, the merged company was renamed JSC Obyedinyonny Kommunalny Operator (JSC OKO).[2] As of 2026, the legal entity is undergoing further reorganization through the absorption of additional legal entities.[3]

Operations

The company's primary line of business is the generation of steam and hot water (thermal energy) by boiler plants; it also provides cold water supply and wastewater disposal.[3] According to the 2025 financial statements, the company's revenue amounted to 17.8 billion rubles (a 26% increase), net profit was 252.4 million rubles, assets reached 46 billion rubles, equity stood at 7.8 billion rubles, and fixed assets totaled 33.6 billion rubles.[3] The authorized capital is 1.447 billion rubles.[3] In the public procurement system, the company has concluded more than 14,300 contracts totaling over 52.1 billion rubles.[3]

Among the information systems deployed are electronic document management on the LanDocs platform (since 2021) and Directum RX (since 2024), the Directum Projects project management system (since 2023), and the CityCom geoinformation platform (since 2026). As part of its investment program, JSC OKO is carrying out a large-scale reconstruction of water supply and sewerage networks along Moscow Highway in Nizhny Novgorod: the total length of the infrastructure being upgraded is 5 km, with construction and installation work scheduled for completion in Q4 2027. On the section from Vyaznikovskaya Street to Dolzhanskaya Street, a pressurized sewer main with a diameter of 1 meter is being reconstructed: plans call for rehabilitating 2.5 km of the existing line and laying approximately 400 meters of new steel pipeline; at the same time, near building 312 on Moscow Highway, replacement of a worn water main has begun — a new trunk water main approximately 2.5 km long, running to building 235, will be built from ductile cast iron pipes with spheroidal graphite, with a service life of 80–100 years.

Thanks to the use of a looped water supply scheme, the upgrade of networks on Moscow Highway will improve the reliability and quality of water supply for residents and organizations in the Moskovsky and Kanavinsky Districts of Nizhny Novgorod.[11] For diagnosing underground pipelines, JSC OKO uses robotic systems capable of inspecting water-filled, silted, and clogged pipes; three such devices can build 3D models of networks accurate to within a millimeter, enabling precise assessment of pipe condition and maintenance planning. In preparation for the heating season, 79 of the company's 116 boiler plants were overhauled, and more than 1,700 sections of heat networks were pressure- and strength-tested.[8] Trial operation of the robotic systems is being conducted on a section of the collector on Permyakova Street; similar equipment had previously been used by utility companies in Moscow and Saint Petersburg.[8][6] From September 2026, JSC OKO switched to independently calculating charges and generating payment documents for cold water supply and wastewater disposal services: residents of apartment buildings in Moskovsky District were among the first to receive the new payment notices.

Upon the transition to direct billing, payments for cold water automatically appear in subscribers' personal accounts on the operator's digital platforms; property owners who had not previously switched to direct contracts for heating and hot water must, after receiving their first invoice, manually add the new account number to their profile, or expedite the process by submitting an application through their management company or homeowners' association.[10][5][4]

Authority

The company's General Director since 3 September 2024 is Sivokhin Dmitry Gennadyevich.[3]
