HIMOINSA supplies 24 MW of power in Kouriah, Guinea

• HIMOINSA has supplied 24 MW of power to an industrial facility in Kouriah, Guinea, using 12 HTW 2030 T5 generator sets.

• The solution addresses frequent power cuts in the area, ensuring a stable electricity supply for a metallurgical industrial site.

• Key components include 8 cylindrical fuel tanks, 20 kV medium-voltage switchgear, step-up transformers, and low-voltage distribution boards.

• The project faced logistical challenges due to limited infrastructure and extreme environmental conditions in Conakry.

• Yanmar Turkey provided essential technical support and medium voltage materials, contributing to the project's success.

• The SCADA system enables real-time monitoring and remote control, optimizing fuel consumption and operational efficiency.

One of the challenges faced during the project was to ensure the supply of electricity during power cuts in the area. HIMOINSA has implemented a comprehensive solution, taking into account the specific characteristics of the Kouriah area and includes 12 HTW 2030 T5 generator sets capable of meeting the energy needs of an industrial site belonging to the metallurgical industry.

HIMOINSA supplies more than 24 MW of power to an industrial facility in a key area for the Guinean economy, located close to the capital, Conakry. The solution will mitigate the effects of the power cuts that have historically been common in this area, causing major complications for the inhabitants and the industrial areas affected. 

HIMOINSA has provided the critical power required by this industrial plant which is located on the main freight traffic and warehouse artery in Guinea. The generator sets had to operate in an environment of high energy demand, ensuring a stable supply in the event of grid outage. 

The client had a number of key requirements for this power solution, which had to be able to guarantee the supply of electricity to a large industrial plant dedicated to metallurgy, without forgetting process efficiency and optimum fuel consumption. The proposed solution had to ensure stability during peak loads, remain operational without prolonged downtime, and be an alternative that could be easily integrated with other existing electric systems in the production plant.

Yanmar Turkey has played a key role in the success of the project, working with HIMOINSA at every stage of the project. From the supply of medium voltage material to the commissioning of the installation, their experience and technical support have been essential to the correct integration and operation of the system.

Integrated turnkey solution

HIMOINSA has designed a project adapted to the conditions required by the client, taking into account the specific characteristics of the environment. The team has been responsible for overseeing both commissioning and testing, ensuring that the entire system operated optimally from the moment it was installed. HIMOINSA has provided a comprehensive solution that includes:

• 12 containerised, high capacity HTW 2030 T5 diesel generator sets to meet the energy demands of the industrial facility.

• 8 cylindrical 47.5 m³ main fuel tanks, to ensure continuous fuel supply and reduce the risk of production stoppages.

• 20 kV medium-voltage switchgear, for safe medium-voltage electricity management.

• 0.4 / 20 kV step-up transformers, to enable efficient conversion of electrical power.

• Low-voltage (LV) distribution boards, for safe distribution of electricity throughout the plant.

• UPS and rectifier systems, to ensure continuity of supply and stability of the power system.

• 2 electrical system containers to optimise space by facilitating the management of the power system.

• A synchronisation system to facilitate the integration and coordination of all the generator sets in operation.

• A SCADA system for real-time monitoring and remote control of the power systems.

• A fuel automation system for functional fuel management and reduction of operational risks.

Challenges | Limited infrastructure

The system has been designed to operate with parallel synchronisation between the 12 HTW 2030 T5 diesel generator sets. These gensets are particularly suitable for high volume industrial applications due to their efficiency and ease of maintenance, which has allowed a balanced load and an effective response to peak demand. The 0.4/20 kV step-up transformers and medium-voltage switchgear are configured to ensure safe and efficient electricity distribution. Fuel automation is key to optimising the use of resources and ensuring that the system operates continuously without interruption.

• Accessibility and logistics: The project presented logistical challenges due to the limited infrastructure and the location of the plant in the city of Conakry, which hampered the delivery and assembly of the heavy and bulky equipment.

• Operating condition: The installation was carried out in an environment with high temperatures and high humidity, especially during the rainy season. Such conditions required equipment capable of working in extreme conditions. 

• Coordination of multiple systems: The complex integration of the automation, control and power systems involved the synchronisation of generators, transformers and SCADA systems and required close collaboration between the engineering and technical teams.

Success and customer satisfaction

The power solution implemented by HIMOINSA has enabled the industrial plant to operate continuously with optimised fuel consumption, thanks to the automation and remote monitoring system. The SCADA system allows the operators to efficiently monitor and control the performance of the generator sets from any location and has improved their ability to respond to any eventuality. In addition, HIMOINSA's ability to offer local technical support has been a key factor in the success of the project.
