Uninterrupted round-the-clock RES-based power supply to remote and isolated territories

We offer smart, efficient solutions for autonomous power supply to areas
where it is not available

Problem

There are many isolated and remote areas in the world. Such places are usually not reached by power lines from "the mainland" and therefore their power supply is organized locally. In Russia, there are localities in remote areas with poor road and energy infrastructure that are not connected to the Unified National Power Grid (UNPG). This includes the territories of the Far East, Karelia, Altai, Komi, Krasnoyarsk region, Arkhangelsk, Irkutsk, Murmansk, Tomsk and Tyumen regions, Khanty-Mansiysk, Yamalo-Nenets and Nenets regions.

About 70% of the territory of Russia with about 20 million population is not connected to centralized power supply.
Fuel, electricity and heat prices in Russian isolated power supply systems are among the highest in the world. On average, economically justified electricity tariffs range from 30 to 60 rubles, but in some areas they reach up to 200-300 rubles per kW*h, primarily due to the high delivery cost of diesel fuel, high wear and technical obsolescence of equipment. Current global trends in mining and processing of minerals, metallurgy, industry and other sectors are aimed at reducing the carbon footprint of enterprises. The introduction of additional duties and charges in the case of high emissions into the atmosphere is being considered, and it is planned to reduce quotas for CO2 emissions.

All these steps lead to the fact that domestic mining and processing companies, if they are focused on the Western market, need to include in their strategies reduction of CO2 emissions, and for isolated and remote areas where the most mining is carried out, it is almost impossible to solve this issue without RES.

Solution

The main global trend in the development of energy in isolated territories is the creation of autonomous hybrid energy supply systems (AHES) based on renewable energy sources (RES). Such systems save fuel, transport costs for its delivery, and at the same time improve the local environment.

AHES is a system that consists of several types of renewable energy generation: wind power plants, solar panels, storage devices, and control systems.

Autonomous hybrid energy supply system

Wind Turbines
Choice factors for optimal solution:

• logistics solution
delivery of bulky cargo strongly affects the solution cost

• installation equipment
heavy crane equipment, falling jib erection method, climbing crane method

• functionality at temperatures up to -40° C.
limited use of some types of wind turbines

Having evaluated the global market potential for wind-generated electricity with the use of wind turbines with up to 1 MW capacity, we have included wind turbines with a capacity from 20 to 1,000 kW in our portfolio.

• 20 kW to 60 kW capacity;
• 60 kW to 150 kW capacity;
• 250 kW to 350 kW capacity;
• 500 kW to 1,000 kW capacity.

Our company has signed agreements for each capacity range solutions with technical leaders who have the best solution for isolated areas of Russia. In each capacity range, we offer the most balanced solutions based on exclusive agreements.

Parameters of a 100 kW wind turbine:
• delivered in standard shipping containers;
• crane-free installation is possible;
• wind turbines operate at temperatures up to -40°C;
• blade heating;
• lack of hydraulics and minimal number of wind turbine friction parts;
• wind turbines operate at wind speeds up to 70 m/s;
• minimal maintenance by local technicians/diesel operators (for example, replacement of brake pads no earlier than after 6-7 years of operation);
• low foundation costs;
• operating experience in harsh climatic conditions.

Parameters of a 300/330 kW wind turbine:
• convenient logistics, blade length 14.5-15.5 m;
• installation using a winch, no crane;
• wind turbines operate at temperatures up to -40°C;
• blade heating;
• lack of hydraulics and minimal number of wind turbine friction parts;
• wind turbines operate at wind speeds up to 70 m/s;
• minimal maintenance by local technicians/diesel operators (for example, replacement of brake pads no earlier than after 6-7 years of operation);
• low foundation costs;
• operating experience in harsh climatic conditions;
• delivered in standard shipping containers.

Parameters of a 1000 kW wind turbine:
• blade length 27.7-29.15 m;
• wind turbines operate at temperatures up to -40°C;
• blade heating;
• lack of hydraulics and minimal number of wind turbine friction parts;
• wind turbines operate at wind speeds up to 25 m/s;
• minimal maintenance by local technicians;
• operating experience in harsh climatic conditions;
Solar Panels
Isolated power systems are used in the Chukotka Autonomous region, Kamchatka region, Sakhalin region and Magadan region, Norilsk-Taimyr and Nikolaevsky power districts, and in power systems of the Northern part of the Republic of Sakha (Yakutia). Electricity is mostly consumed in winter when daylight hours are very short or during polar nighttime. For hybrid systems, with wind turbines available, solar generation has a positive effect in terms of good output in summer, when the wind speed is relatively minimal.

Equipment is delivered directly from the manufacturer.
Storage Devices
It is required to use storage devices (mainly Li-Ion) in a RES-based autonomous hybrid power system, since energy generation from a wind power station (WPP) and a solar power station (SPP) is practically not predictable in the short term. Our solutions and expertize allow us to count on the service life of storage systems from 7 to 10 years, which also affects the operating cost of the solution.
Automated Control System With Energy Converters
Control system is a key part in an autonomous hybrid power system. In Russia, a number of companies are developing solutions for generation control and storage device control. Our company has solutions based on both domestic and foreign developments with an exclusive agreement with a manufacturer who has a global experience in projects for isolated areas, with the possibility of combining various types of generation, diesel generator sets (DGS) and energy storage devices. The key feature of this solution is the combination of renewable energy generation and energy storage over a DC bus with the creation of a full-fledged microgrid with smart components (microgrid), which includes a fully autonomous solution with minimum service, with the exception of DGS.
