The heating season is now over for Petrozavaodskaya CHPP JSC TGC-1; the comprehensive overhaul and modernization of the city’s heating network continues.

On 15 May 2014, pursuant to an Order from the Petrozavodsk District Municipal Administration, the Petrozavodskaya CHPP, a strategic producer of heat energy and electricity for the capital of Karelia, switched to summer operational mode.

During the autumn-winter heating season, the Petrozavodskaya CHPP provided a reliable supply of electricity and heat energy to the residents of Petrozavodsk, without any major disruptions occurring in the operation of the main heating network or the plant's cogeneration heating system. This year, the heating season lasted 233 days. Minus 22.4°C was the lowest recorded temperature and + 11.5°С was the highest. During this period, the Petrozavodskaya CHPP produced 1.4 million GCal of heat – 200,000 more than during the previous heating season, which was the coldest in the past five years.

Every year, the Petrozavodskaya CHPP conducts a series of measures designed to overhaul and modernise the plant’s key and auxiliary equipment and the main heating network. This year, it is planned to repair and overhaul turbine unit №2 and water-heating boiler №4, and to conduct an intermediate repair of turbine unit №3. In addition, TGC-1 is planning to continue the comprehensive programme to improve the city’s heating network infrastructure.

— In 2007, JSC TGC-1 launched an extensive programme to modernise the heating network, – said Aleksandr Vdovichenko, Director of the Petrozavodskaya CHPP.— In 2009, the reconstruction of a 1,138m section of transit pipeline along Komsomolskiy Pr. was completed with a double-pipe system. In 2011, a 1,616 m section of double-pipe along Vedlozerskaya St. was commissioned. Work on these two sites involved increasing pipe diameter and installing modern foam polyethylene-insulated pipes. At the end of May, we are starting comprehensive works to modernise a 1,760 m section of transit pipeline along Shotman Str., from Studencheskiy Lane to the Drevlyanskaya Embankment. TGC-1’s investment programme for the extensive modernisation and overhaul of this section of pipeline is over RUR 358 million. This section of the main heating network has been in operation since 1978 — it was laid in inaccessible trenches with poor drainage, in soil with a high level of humidity. In conditions such as these, the pipeline is exposed to corrosion and other potential defects.

Following the main heating network infrastructure’s extensive development, the provision of heat energy to over 40% of consumers — the residents of the Golikovka, Zareka and Kukkovka districts — will be more reliable and effective.
