On MET Groups Power Systems team, we pride ourselves on delivering cutting-edge high voltage (HV) infrastructure design and technical support that powers the world today while preparing it for the challenges of tomorrow. Our expertise spans a wide range of services, from embedded generation and renewable energy solutions to power distribution network design and ongoing maintenance for commercial buildings. With a commitment to innovation, safety, and reliability, we partner with clients to create tailored electrical systems that meet their unique needs and comply with the highest industry standards. In this blog, we’ll explore how MET Group approaches HV infrastructure design and technical support, breaking down our comprehensive capabilities.
HV Infrastructure Design and Technical Support Capability
Our approach to HV infrastructure design begins with a deep understanding of each client’s operational requirements and the specific demands of their site. Whether it’s integrating renewable energy sources or designing robust power distribution networks, we bring a holistic perspective to every project, ensuring efficiency, scalability, and long-term performance.
Embedded Generation and Power Distribution Network Design
We specialize in designing systems that incorporate embedded generation, such as Combined Heat and Power (CHP), Photovoltaic (PV)Â panels, hydroelectric systems, and HV/LV power distribution networks. Our process starts with assessing the feasibility of integrating these technologies into your infrastructure. For instance, a CHP system might be ideal for a commercial building needing both electricity and heat, while PV panels could suit a site with ample sunlight. We then design the HV and LV networks to distribute this power seamlessly, optimizing cable sizing, switchgear placement, and load balancing to minimize losses and maximize reliability.
Site-Specific Renewable Energy Assessments
Every project begins with an initial site-specific renewable energy assessment. Our team evaluates factors like solar exposure, water flow, and existing grid connections to provide tailored guidance on the best renewable solutions. This step ensures that your investment in technologies like PV or hydro is both practical and cost-effective, laying the groundwork for a sustainable design that aligns with your energy goals.
DNO/IDNO/ICP Substations and Interfaces
We excel in designing and supporting DNO (Distribution Network Operator), IDNO (Independent DNO), and ICP (Independent Connection Provider) substations and interfaces. Our services include detailed studies—such as load flow and fault level analyses—and bespoke designs that ensure compatibility with utility networks. From specifying transformers to configuring protection systems, we handle every aspect to guarantee a smooth connection to the grid, whether for a new development or an upgrade.
Client-Owned Networks and Substation Design
For clients managing their own networks, we offer end-to-end substation design and technical support, coupled with power systems control integration. We design substations that meet your specific load requirements, incorporating advanced control systems for real-time monitoring and management. Our technical support extends beyond installation, providing ongoing expertise to keep your network running efficiently and safely.
Generation and System Integration
Integrating generation into your power system is a complex task that demands precision and foresight. At MET Group, we manage every detail to ensure your generation assets work harmoniously with your infrastructure.
Switchgear, Generation Automation, and Interface Design
We design switchgear and automation systems that control and protect your generation assets, such as CHP units or PV arrays. Our interface designs ensure these systems integrate seamlessly with the wider network, featuring user-friendly controls and robust safety features to prevent faults and downtime.
HV/LV Grading and Power System Studies
To safeguard your system, we conduct HV/LV grading studies and power system analyses, including short-circuit and protection coordination studies. These ensure that circuit breakers and relays operate correctly under fault conditions, protecting equipment and maintaining uptime across your HV and LV networks.
Generation Earthing Systems and Grid Code Compliance
A reliable earthing system is critical for safety and performance. We design earthing solutions tailored to your generation setup, ensuring compliance with grid codes like the UK’s G99 standard. This includes verifying that your system meets voltage, frequency, and stability requirements for grid connection.
G99 Verification and Commissioning
Our G99 verification and commissioning process ensures your generation equipment complies with national regulations. We perform thorough testing—covering everything from protection settings to grid synchronization—before handing over a fully operational system, complete with Technical Reports (TR) for regulatory approval.
Generation Control Systems
We implement generation control systems that allow precise management of output, balancing supply with demand. These systems use advanced technologies like SCADA to provide real-time data and control, enhancing efficiency and reliability.
Ongoing Maintenance for Commercial Buildings
Our commitment doesn’t end with installation. For commercial buildings, we offer ongoing maintenance to keep your HV infrastructure and generation systems in peak condition. This includes:
Routine Inspections: Checking busbars, switchgear, and connections for wear or faults.
Preventative Maintenance: Tightening bolts, testing protection devices, and updating control software.
Reactive Support: Responding quickly to issues like power outages or equipment failures.
Documentation: Maintaining detailed records to track performance and compliance over time.
For example, in a recent project, we isolated a busbar in a commercial facility to tighten bolts and conducted follow-up maintenance to ensure long-term reliability—all while minimizing disruption to occupants.
