24/7 Heat and Power with MWM and Cat Gas Engines for Sayuri Permafrost Greenhouse Complex in the Coldest Inhabited Place on Earth
Mannheim, August 03, 2021
The Sayuri agricultural complex is based in Yakutia in northeast Siberia. The region is faced with challenges such as temperatures fluctuating more than 100°C (180°F). Yakutsk is located on permafrost ground that does not allow the cultivation of fruits and vegetables. The solution: a large greenhouse that offers crops heat and light for optimum growth and that prevents temperature extremes. To continually supply the Sayuri greenhouse complex with heat and power, the power plant for the energy generation was equipped with three power gensets. An MWM TCG 2020 V20 gas engine and two Cat G3516 gas engines ensure the reliable operation of the greenhouse under permafrost conditions.
Autonomous Energy Supply for Hassle-Free, Uninterrupted Operation
The greenhouse complex was built for the year-round supply of the inhabitants of Yakutsk with affordable, high-quality fruits and vegetables. The project was developed and rolled out in several stages by the regional administration of Yakutsk and JSB Almazergienbank with the support of the government of the Republic of Sakha, Yakutia, and the Japanese investor Hokkaido Corporation. In the first phase, a pilot greenhouse with an area of 1,000 m² was commissioned in December 2016. By 2020, the greenhouse area was expanded to 3.2 ha. In 2021, the Sayuri greenhouse is to produce some 1,250 t of cucumbers and about 230 t of tomatoes. By the time the building work is completed in 2022, the production output is to be boosted by another 40 percent.
The greenhouse is supplied with energy from the on-site power plant. In this way, it is possible to react speedily to production or climate changes. The independence from external energy suppliers allows the quick and flexible adaptation of the heat and power supply of the greenhouse complex in response to production or climate changes. The main production system is based on gas-fueled power gensets. On the premises, three gas gensets—an MWM TCG 2020 V20 gas engine with an electrical output of 2 MW and two Cat gensets with an electrical output of 1 MW each—produce heat and power for the greenhouse facilities. The latest extension, with the installation of the 2MW genset, was carried out by the MWM distributor Electrosystems Ltd. To make the containerized power plant resilient to fluctuating temperatures, Electrosystems Ltd. implemented a number of special modifications, e.g. additional heating systems in external water circuits and container wall insulation.
MWM TCG 2020 V20 Gas Engine in CHP Operation: “Outstanding Reliability”
During the first winter operation, the MWM TCG 2020 V20 gas engine took on the main load and delivered energy without any interruptions despite extreme temperatures of 60°C (76°F) below zero. The energy generated via combined heat and power (CHP) generation greatly benefits the TCO of the greenhouse complex: While the energy costs with power purchased from the public grid amounted to ₽4.86/kWh, the operation of the internal CHP plant with natural gas has brought down the costs to ₽2.50/kWh.
Following the go-live in August 2020, the MWM gas genset completed its first 1,500 operating hours in March 2021. In view of the positive experiences with the MWM gas engine, the Sayuri management plans on purchasing another MWM TCG 2020 V20 gas engine in order to supply the last building section of the premises with sufficient power. “We are impressed by the outstanding reliability of the MWM gas engine, which never failed during the entire winter season”, says Valery Garipov, representative of Sayuri. “Thanks to the TCG 2020 V20 gas engine, the profitability of the plant has also improved compared to when we used to purchase electricity.”
The MWM TCG 2020 gas engines are custom-tailored to the challenges of different applications. The MWM gas engines in the output range from 1,000 to 2,000 kWel ensure efficiency, reliability, flexibility, environmental compatibility, low TCO, and high profitability.
