Engineering services for utility-scale Battery Energy Storage Systems (BESS), renewables, rail electrification, and transmission & distribution networks up to 132kV.
Precision commissioning and technical leadership delivering risk-free substation energisation.
Comprehensive custom logic development, tripping matrices, and parameter configuration for numerical IEDs (including ABB Relion REX640, REF615, RED615, Siemens SIPROTEC, and MiCOM). Advanced scheme design for transformer differential, restricted earth fault, and AVR/tap changer control.
Design, configuration, and end-to-end verification of digital substations. Specialist engineering of GOOSE trip/block schemes, managed Ethernet switch architectures, PRP/HSR redundancy rings, and direct SCADA integration.
Rigorous full-scope site commissioning: secondary injection testing, CT/VT magnetisation and ratio checks, overall tripping audits, primary plant diagnostics, and formal ENA EREC G99 compliance testing.
Direct technical site leadership, authoring high-voltage operating philosophies, safety coordination, and managing formal witness testing alongside DNOs and client representatives through to final energisation.
Specialist High Voltage (HV) and Low Voltage (LV) electrical testing, protection commissioning, and substation automation engineering.
Operating across utility-scale Battery Energy Storage Systems (BESS), renewable energy generation, transmission & distribution networks, and rail infrastructure, we deliver high-complexity engineering solutions up to 132kV.
Our focus centers on numerical protection relay configuration, complex scheme logic, and IEC 61850 digital substation architectures. We deliver expert on-site commissioning and testing to protect critical assets, ensure full network compliance, and bring substations safely to energisation.
Engineered to meet the standards of UK DNOs, National Grid, and major EPC contractors.
