HIMOINSA has delivered 10 HGY Series generator sets for a mission-critical project that operates exclusively on HVO100 fuel.
HIMOINSA, an international leader in the design and manufacture of power technology solutions, and part of Yanmar Energy Systems, is supplying ten HGY Series generator sets, with a total critical power output of 20 MW, ensuring a reliable supply of low-carbon energy.
This capacity market project requires generator sets that are ready to supply power at any time. The ten units installed work in synchronisation with each other and with the grid under a smart control system, which ensures stable and safe operation at all times. Real-time remote monitoring, combined with communications redundancy and fixed load export, allows the plant to maintain a constant flow of electricity without interruptions.
This project with the HGY Series is a milestone in terms of sustainability, efficiency and reliability, combining the most advanced technology, such as the HIMOINSA generator set with the Yanmar YG engine, operating exclusively with HVO100, which allows the power plant to guarantee NOx emissions below 190/Nm³, reducing them to a minimum thanks to the existence of an SCR and a class-leading power density of up to 37.9 kWm/L.
“HIMOINSA has already supplied equipment for the capacity market in the United Kingdom, including both diesel and gas generators, but with this project we are emphasising the maximum performance and efficiency of HGY generators with Yanmar engines. We are convinced that we are providing our customer with a complete solution. Equipment designed with the latest technology, guaranteeing low emissions and maximum performance. Without a doubt, this is one of the most competitive solutions currently available in the power generation sector for mission-critical projects,” explains Clive Dix, Managing Director of HIMOINSA Power Solutions in the United Kingdom.
A sustainable solution | Minimizing carbon footprint
What is the first power station in the United Kingdom to operate with HVO100 incorporates advanced after-treatment systems and operates exclusively on HVO100 fuel. This renewable plant-based biofuel significantly reduces the carbon footprint compared to conventional diesel, while ensuring stable and reliable performance in mission-critical applications.
The HGY Series has also been designed to comply with the most demanding environmental regulations, such as the Mid Combustion Plant regulation adopted by DEFRA (Department for Environment, Food & Rural Affairs) in the United Kingdom. This regulation applies to generation plants between 1 MW and 50 MW, especially those that can operate more than 500 hours per year.
For exhaust gas treatment, the generator sets incorporate a latest-technology Selective Catalytic Reduction (SCR) system. This system injects a urea solution into the hot gas flow, causing a chemical reaction that converts nitrogen oxides (NOx) into nitrogen and water vapour, compounds that are harmless to the environment.
In addition, the SCR system installed in the HGY Series is integrated with the engine’s electronic control unit, allowing real-time monitoring of parameters such as temperature, pressure and NOx concentration. This connectivity ensures comprehensive process control, reduces the risk of incidents and extends the service life of components. Thanks to this approach, NOx emissions are kept below 190 mg/Nm³, positioning the plant at the forefront of sustainable power solutions in Europe.
The combination of SCR with the exclusive use of HVO100 makes this power plant a benchmark: not only does it meet the most rigorous sustainability standards, but the plant also benefits from exceptional power density, reaching up to 37.9 kWm/L, which means a lower carbon footprint, greater efficiency in the use of resources and a significant reduction in life cycle costs.
Advanced acoustic engineering
The project required an advanced acoustic solution. The HGY Series incorporates the latest technology of HiAcoustic solutions, allowing soundproofing levels to be set at 80 dB(A) at maximum output. This flexibility ensures that the plant can adapt to the strict acoustic requirements of the British environment, minimising its impact on the local community and complying with the highest environmental standards.
To this end, each generator set has been designed with acoustic panels of different densities on the walls, ceiling and floor, using mineral wool and specialised foams that effectively absorb sound waves. In addition, the exhaust silencers integrated into the system guarantee a reduction of between 30 and 45 dB, keeping noise under control even during peak operation.
HIMOINSA has worked with its acoustic engineering team to offer an advanced solution. The system is completed with optimised air flow, channelled through dual-module ventilation and self-regulating remote cooling, which adjusts the flow rate according to thermal requirements. This design not only ensures maximum efficiency in heat dissipation but also reduces the noise level associated with air movement and auxiliary load consumption. In this way, the plant can operate intensively in an urban environment in the United Kingdom, maintaining supply reliability and complying with the highest European environmental standards.
Yanmar engine | Reliability at the highest level
The Yanmar engine is developed to offer quality, durability and high performance under the most demanding conditions. These engines feature common-rail injection systems, as well as an advanced piston head design and comprehensive fluid analysis that optimise combustion and improve efficiency. The ECU allows for start-up in less than eight seconds and ensures compliance with class G3 of the ISO 8528-5 standard, making the installation a solution with immediate response capacity for any critical power need.
In addition, the ECU incorporates intuitive diagnostic software that enables remote monitoring and predictive maintenance, facilitating comprehensive plant management and increasing operational availability. This combination of technological innovation and mechanical robustness makes Yanmar engines the guarantee of reliability on which this 20 MW project is based.
24/7 Connectivity and control
This 20 MW project, configured with ten synchronised and continuously monitored generator sets, ensures a stable, secure and uninterrupted supply.
This advanced connectivity reinforces the plant’s ability to adapt to constant load and guarantees continuity of service even in the most demanding conditions. This consolidates a model of intelligent and redundant supervision, essential in mission-critical environments where reliability is a non-negotiable factor.
