Project overview

YANMAR Energy System participated in the NEDO’s international demonstration project for a high-efficiency energy supply system by constructing a microgrid including wind power environment in Tiksi, where is an independent grid area in the Republic of Sakha, Russian Federation.
This demonstration project aimed to achieve energy-saving and renewable energy effects as well as greenhouse gas emission reduction targets.

World's first demonstration project in an extremely cold region

Tiksi, the target area of the project, is located on the coast of the Arctic Ocean and relies on diesel on-site power generation for much of its electricity.
Due to high fuel transportation costs, the Republic of Sakha is one of the regions with the highest cost of power generation by diesel generators.
This project was initiated in response to the Tiksi region’s need to reduce the cost of power generation by introducing renewable energy technologies to create a locally produced, locally consumable power supply system.
The renewable energy control and coordination system, which realizes optimal operation of wind and diesel power generation, controls renewable energy output in an integrated control through predictive use of renewable energy and advanced operation of energy storage facilities.
This is the world’s first such demonstration project in an extremely cold region of -30°C or lower.
The efficient operation of wind and diesel power generation, as well as storage batteries, is expected to reduce diesel fuel burning by approximately 16% per year compared to previous levels.
Diesel generators that are highly reliable and easy to maintain are essential for the optimal operation of these microgrids. YANMAR’s power generation system was selected through a rigorous bidding process based on the our many years of experience and advanced technological capabilities.

Handling the technical challenges

YANMAR Energy System installed a total of 3 MW of diesel generator system as part of an IoT-enabled Polar hybrid microgrid.
The diesel generators provided important performance as grid stabilization and maximization equipment by compensating for long-period fluctuations in the wind turbine generators.
The biggest challenge for us in this project was dealing with a major specification change during the course of the project.
To meet Client’s request to change the generator fuel to “crude oil-fired,” our sales, development, and engineering teams worked together to develop and design a new application through a series of thorough site surveys to create the best specifications.
In addition, a hot water circulation system utilizing waste heat between the three generators was installed to provide added value by efficiently using the waste heat to heat the generator room.

Remote commissioning due to the coronavirus pandemic

Just prior to the delivery of equipment to the site in 2020, the Covit-19 infection spread globally, and we were suddenly forced to conduct on-site supervision remotely after delivery to the site.
In particular, the time for commissioning was approaching at the end of 2021, but the inability to travel from Japan caused us much concern.
Even under such circumstances, with the cooperation of engineers from Yanmar Turkey and engineers from RODEN-DV, Yanmar’s service partner in Vladivostok, we were able to complete the commissioning as planned while supervising remotely from Japan.
This was our first attempt to remotely supervise a commissioning, and although the special specifications of the crude oil-fired system presented many difficulties, we were able to successfully complete the task, which was greatly appreciated by the client companies. Takaoka Toko, the consortium’s Prime contractor, and Mitsui & Co., the managing company, also thanked Yanmar for its customer-first attitude.
We are very grateful for the support of the various participating companies and the cooperation of all teams within YANMAR that made this great challenge a success.

We express our condolences to all the victims of Russia’s invasion of Ukraine and wish for a speedy end to this tragedy.
