The modernized turbo generator No. 7 was launched at the Avtovskaya CHPP of TGC-1
(part of the Gazprom Energoholding Group).
Taking part in the event via a video link were Alexey Miller, Chairman of the Gazprom Management Committee, and Alexander Beglov, Governor of St. Petersburg.
The Avtovskaya CHPP, which has been active since 1956, is one of the essential energy suppliers in the southwestern part of St. Petersburg. The plant provides heat and power to private consumers in the Admiralteysky, Moskovsky, Kirovsky and Krasnoselsky Districts along with 236 healthcare, children's, educational and cultural entities, including the National Library of Russia, as well as subway and railroad infrastructure facilities.
The works performed have made it possible to enhance the reliability of heat and power supplies to consumers. The modernization effort involved the replacement of the core process equipment of turbo generator No. 7, as well as auxiliary equipment and utility systems. Among other things, a new generator with an air cooling system was installed in addition to a new turbine with a state-of-the-art control system. All of this equipment was produced in Russia. The generator's power capacity was increased from 97 MW to 116.4 MW, and its thermal capacity went up from 174 Gcal/h to 188.4 Gcal/h.
The project was implemented with the use of digital technologies: a 3D model of the equipment undergoing modernization was created with maximum accuracy. As the construction processes were overseen in a digital environment, the project could be, inter alia, carried out without suspending operations: during the entire renovation period, the plant continued to provide consumers with energy.
The modernization of turbo generator No. 7 is the first stage in the renovation of the Avtovskaya CHPP. The second stage will include the modernization of turbo generator No. 6 and the renovation of utility infrastructure.
