Transneft Volga Region Commissions Photovoltaic Power Supply System at Central Production Service Shop

Date of publication: 06 March 2019 Print

Transneft Volga Region has commissioned a photovoltaic power supply system (PVS) with the capacity of 252 kW at Central Production Service Shop (CPSS) in Novokuibyshevsk.

The installation of the solar power plant began in August 2018 and was completed in three months. The solar modules installed at CPSS were manufactured in Russia using heterostructure technology. This technology implies using new-generation silicon solar cells with high efficiency of more than 22% and wide operating temperature from -60°С to +85°С.

The photovoltaic system takes up 1,441 square metres. The system is monitored from CPSS’ Chief Power Engineer’s workplace.

The PVS, consisting of 842 solar panels, will partially reduce the amount of energy purchased from a third-party energy supplier, in support of domestically produced energy.

In order to reduce the payback period of the project, the generated electrical energy will be supplied directly to CPSS’ internal 0.4 kV electrical networks through grid-tie inverters without using storage devices. Grid-tie inverters make it possible to simultaneously use the generated electrical energy and electrical energy supplied from an external power supply source.

The solar panels’ service life is 25–30 years. The PVS was commissioned in trial mode in November 2018, the electricity generated in a month amounted to 10 thousand kW/h.

The measures on using the PVS to generate electrical energy were implemented as part of Transneft Volga Region’s energy saving programme. The beginning of the works was timed to the Year of Energy Saving declared at Transneft in 2018.

Due to the absence of the fuel component, using the PVS implies low operating expenses and minimises carbon dioxide emissions into the atmosphere. Economic and environmental efficiency are the Company’s operating principles when it comes to alternative energy.

The PVS is expected to produce about 327 thousand kW/h of electrical energy annually.
