High-Voltage Connections for the UK’s Most Demanding Environments

TSG Power Delivers

As the United Kingdom (UK) heads toward a more electrified and digitally connected economy, the demand for resilient, high-capacity electrical infrastructure is rising sharply. From logistics hubs and data centres to airports and industrial estates, large-scale enterprises require robust high-voltage (HV) connections to ensure operational continuity, energy efficiency and future scalability.

TSG Power, a specialist in high-voltage and medium-voltage (MV) electrical infrastructure, is pivotal in delivering these essential systems. With full National Electricity Registration Scheme (NERS) accreditation (via UCP Choice, a TSG company) and Lloyd’s Register certification, TSG Power provides end-to-end solutions that support high-dependency environments across the UK.

A Fully Integrated Framework

As a full-service Engineering, Procurement and Construction (EPC) contractor and Independent Connection Provider (ICP), TSG Power offers a fully integrated project execution model. This means clients benefit from a single point of accountability throughout the project lifecycle: from initial feasibility studies and grid connection applications to civil engineering, cable laying, substation installation and long-term maintenance.

TSG Power’s in-house engineering teams conduct detailed connection studies and electrical modelling to ensure optimal system design and performance. These studies consider current and future load requirements, fault level analysis, protection coordination and compliance with Distribution Network Operator (DNO) and Independent Distribution Network Operator (IDNO) standards.

By managing the entire process, TSG Power ensures seamless integration with the grid and minimises the risk of delays, cost overruns or compliance issues. This approach is particularly valuable for challenging or time-sensitive projects where coordination between multiple stakeholders is critical.

Certified to Deliver Advanced Infrastructure

TSG Power’s credentials reflect its capability to implement large-scale infrastructure safely and efficiently. The company holds full NERS accreditation, which authorises it to carry out contestable works on behalf of DNOs. This includes the installation of HV and MV cable networks, substations, switchgear and associated civil works.

In addition, TSG Power is certified by Lloyd’s Register, a globally recognised authority in engineering assurance. These certifications demonstrate the company’s commitment to quality, safety and technical excellence, which are essential attributes when working on high-risk, high-value infrastructure.

TSG Power fulfils its role as an Independent Connection Provider (ICP) via UCP Choice, a dedicated subsidiary under full ownership of TSG UK, ensuring seamless coordination with network operators. The company manages all aspects of the grid connection process, including applications, design approvals, inspections and energisation. This ensures that new connections are completed on time, on budget and compliant with all regulatory requirements.

Core Capabilities and Technical Expertise

TSG Power’s core capabilities span all aspects of HV and MV infrastructure. These include:

• HV and MV Distribution Systems: Custom-designed to meet the energy demands of large-scale operations.
• Switchgear Installation and Commissioning: Ensuring safe and reliable control of electrical power flows.
• Transformer Cabinets and Protection Systems: Engineered for efficiency, safety and long-term durability.
• Smart Metering and Energy Monitoring: Providing real-time energy usage and system performance insights.
• Building Energy Management Systems (BEMS): Enabling intelligent control of energy consumption across facilities.
• AC/DC Electrical Studies and Load Analysis: Supporting optimal system design and operational planning.

Each system is designed to be scalable, allowing clients to expand capacity as their energy needs evolve. Whether supporting electric vehicle charging infrastructure, data centre expansion or industrial automation, TSG Power provides future-ready solutions that adapt to changing demands.
