A 150 MW gas turbine power plant consisting of three Siemens SGT-800 turbines is being built at the largest power facility in Belarus. This GTPP is assigned the function of a safety (standby) source of electric energy. The project is being implemented in accordance with a set of measures to integrate the Belarusian nuclear power plant into the country's unified power grid.

The equipment of the future peak-standby power plant is highly maneuverable – it will take no more than 15 minutes to launch it and quickly fill the power deficit in the power grid. For comparison, starting from the cold state of existing Lukomlskaya SDPP power units takes several hours.

The General contractor of the construction RUE Belenergostroy - the management company of the holding currently performs preparatory work for the installation of foundations and mounting of gas turbine units (GTU), process and auxiliary equipment.

In addition to GTPP-150MW, three more peak-standby energy sources based on SGT-800 GTU are being created in the Republic of Belarus. The facilities will be built at the sites of existing thermal power plants of the RUE Minskenergo, Brestenergo and Vitebskenergo.

At the Minsk CHPP-5 will operate GTPP with a capacity of 300 MW consisting of 6 SGT-800 GTU, at the Berezovskaya SDPP – GTPP-254MW (5 turbines), at the Novopolotsk CHPP – GTPP-100MW (2 turbines). It is assumed that the operating time of each peak power facility will be approximately 700 hours per year and up to 350 starts from the cold state.

New capacities are aimed at increasing the reliability and flexibility of the Belarusian power grid. Gas-turbine power units will be used as a reserve both for the existing infrastructure and for future wind, solar and nuclear power plants. The project also contributes to the decarbonization of the economy and the transition to a new energy structure in Belarus.

The full-range equipment supplier is Siemens Energy AB. The full scope of supply includes 16 turbines with generators, gas receiving stations, booster compressors, high, medium and low voltage equipment, as well as PCS7 control systems.

As part of this project, the Russian Company ENERGAS, together with its Swiss partner Enerproject SA, will supply for Siemens set of gas treatment and fuel supply equipment – gas receiving stations (GRS) and gas compressor stations.

Four ENERGAS GRSs (one for each peak GTPP) will be installed on supply pipelines for purification, fiscal metering and heating of fuel gas entering the turbines of power generating units. The capacity of process units is from 29,210 to 87,506 cubic meters of gas per hour.



Two Enerproject gas compressor stations on the Novopolotsk site will boost fuel gas pressure from 1 to 3 MPa before it is fed to the GTPP-100MW. The unit capacity of these block-modular units is 21,960 kg / h. To other gas turbine power plants, the source gas is supplied under high pressure (about 3 MPa), which eliminates the need for its compression.

REFERENCE:

The Siemens SGT-800 industrial gas turbine unit combines robust design, high efficiency and low emissions. Turbines can operate on different types of fuel and in various operating conditions. Development began in 1995, after 2 years the SGT-800 was brought to the market, and in 1999 the first launch took place. Currently, there are over the 370 units in the world with capacity from 47.5 to 57 MW. Their total operating time is more than 7 million equivalent hours of operation with a reliability rating of 99.8+.

REFERENCE:

The construction of Lukomlskaya SDPP began in 1964. On December 22, 1969, the first power unit with a capacity of 300 MW was launched. In 1992, the plant switched to natural gas as fuel. During the decade from 2003 to 2013, phased upgrade of the main and auxiliary power equipment was carried out here, aimed at increasing its reliability, efficiency, service life, and improving operational characteristics.

SDPP today is the flagship of the Belarusian energy industry and the most powerful power plant in the Republic. It is located in the city of Novolukoml. The installed capacity is 2,889.5 MW. Annual electricity output ranges from 7.5 to 12 billion kWh.
