    HIMOINSA supplies 18 MW of continuous power with gas generators to cover the growth of demand in the electrical market of the British West Midlands
             CASE STUDY | 9x1930 kW | 18 MW  | West Midlands (UNITED KINGDOM)

               

    Summary:


    Location: West Midlands (United Kingdom)

    Installed Power: 9 x 1,930 kW  | 18 MW (COP)

    Generator sets: 9 HGM-2370 T5 NG units in a container

    Special configuration Gas generator sets connected in parallel to the public grid that provide energy at a constant load for 2,500 hours a year.

    HIMOINSA distributor: Ocktcom Limited

    Located in the central-western part of the British Isles, the West Midlands region of the United Kingdom is known for its high population density, close to three million people, and for being one of the most important commercial, healthcare and financial areas of the UK.

    Considered a major development area, it has been subjected to a growing energy demand in recent years. In this context, power plants that support the public grid become the best solution to assume the constant increases in electricity demand. These plants have been adapted to a more sustainable productive model using environmentally friendly fuel that reduces carbon emissions, NOx, CO2 and particles.

    In order to contribute to sustainable development, HIMOINSA and its local distributor Ocktcom Limited, have designed a power plant composed of nine gas generator sets connected in parallel to the grid. These gensets supply the electrical grid with a total of 18 MW of power at constant load for 2,500 hours per year.

    OBJECTIVE

    The objective of the project was to release into the public grid, a continuous flow of power to cover the growth of demand for electricity and/or natural fluctuations in generation from renewable sources. The project required the gas generator sets to be activated immediately, and they had to be able to start up in a short period of time and to provide the grid with 100% of the installed power in a few minutes.

    The generation plant has been built in an area close to a residential district, and because of that, special solutions have been implemented in terms of soundproofing able to avoid any acoustic impact.

    SOLUTION

    The main priority of HIMOINSA and of its distributor Ocktcom was to choose the most sustainable and safe technology, ensuring the lowest possible acoustic and environmental emissions. The answer: generator sets with high power gas engines connected in parallel to generate stable power. These generators ensure an effective response to fluctuations in the power supply, generating 18 MW of power at constant load with a maximum use of 2,500 hours per year.

    These generator sets have been installed in containers with special ultra-soundproofed insulation that even go above and beyond the legal requirements dictated by the MCPD (Medium Combustion Plant Directive) in the field of acoustic emissions.

    The results obtained even improve the limits set by the regulatory directive and thanks to the work we have carried out in collaboration with Ocktcom we have obtained record sound levels. I’d say it is most unlikely that they have ever been matched before in a plant with these characteristics


               

    Technical Specifications:



    Specially sized and soundproofed containers were used, that ensures a sound level of 65dBA at a distance of 1 meter. In addition, a special double silencer exhaust system was added to ensure the sound level without affecting the operation of the engine.


    The generator sets feature natural gas engines capable of providing 1,930 kW of power, with high mechanical resistance and low emission levels of particles, CO2, SOx and NOx: 250mg/Nm3 of the latter at 100% of the load. These emission levels are perfectly in line with current regulations and represent an improvement in terms of environmental sustainability compared to their diesel-powered counterparts.


    We decided to use control units with integrated PLC that were adapted by HIMOINSA to guarantee a safe and efficient parallel connection between the groups and the grid, as well as their remote management by the plant user. This system makes it possible to coordinate the transfer of power into the grid to ensure a continuous supply.

    The cooling system is controlled via a frequency converter, which maximizes the electrical efficiency of the generator set by reducing its consumption to the minimum necessary at all times.




    To guarantee the highest possible safety levels, the generator sets feature a host of safety sensors (smoke, gas…) and they also have ATEX emergency ventilation in the container, thereby guaranteeing safe ventilation of the cabin.
