Electrical and Thermal Energy Supply
The main type of activity for this area is thermal and
electrical energy production and selling to consumers. Consumers (Subscribers)
are the enterprises of the Izhorskie Zavody Industrial Zone and the State
Unitary Enterprise “Fuel and Energy Complex of Saint Petersburg”, which
provide with energy the housing and communal services facilities of Kolpino
- The set
output of generating equipment: for electrical energy is 110 MW; for
thermal energy is 555 MW (477.7 Gcal/h). Heating networks – more
than 100 km (as a single pipe) with the capacity of more than 12,000 m3.
schedule of the enterprise – twenty-four-hour in two 12-hour shifts. The
average staff number in GSR TETs JSC – 184 employees.
- GSR TETs
JSC structural units consist of the following:
- new GSR
Energy CCGT-TPP (2014);
VK-2 water boiler station (2020);
and management units.
During the period of 2011–2014, the energy
generating equipment operation and maintenance management project was realized
together with Fortum company in accordance with Fortum TOPGen® standards.
The profound modernization of one of the largest boilers of Saint Petersburg
in Kolpino (465 MW) in 2018–2020 was realized without thermal energy
supply disconnection with the high level of heat supply in the houses of
Kolpino inhabitants and workshops of industrial enterprises.
To equip new station, the most advanced equipment was purchased:
- PG6111FA gas turbine manufactured by General
Electric, it s emblematic that the gas turbine serial number ends with 078
(Saint Petersburg code);
- two-pressure waste-heat boiler manufactured by
Machine-Building Factory of Podolsk OJSC;
- steam turbine with
regulated heat extraction of T-25/33-7,6/0,12 type manufactured by Kaluga
Turbine Works OJSC.
Today, steam and gas cycle technology is the
most effective one and, moreover, the most ecologically clear and safe.
In 2020, the modernization of the water boiler station was
The purpose of the Water Boiler Station No. 2 (VK-2) modernization is to
reduce operational costs and enhance the heat generating equipment operation
efficiency. The following main tasks are resolved:
Implemented actions allowed to remove
restrictions on the water boiler station heating power production, which were
related to the hydraulic mode.
- On the basis of the
Water Boiler Station, a heating power distribution center was created. In
connection with the above, the following technical re-equipment actions
to makeup plant;
to network installation;
electric power supply system modernization was performed;
automation and management systems were implemented.
- The VK-2 boiler station
operation in summer time was provided in circulation mode that allows to
prevent the source disconnection for the boiler equipment repair work.
- It is excluded to use
steam for heat supply as hot water.
- Assemblies for the
automatic regulation of the heating network parameters at city and
industrial site outlets were installed.
- Actions to improve the
hydraulic mode of consumer heat supply were performed.
- In the boiler, modern
equipment and new software to manage operation modes were installed. It
will further allow to ensure the reliable and qualitative heat supply of
industrial enterprises and inhabitants of Kolpino.
