SSDE Onshore Substation — 400 kV Earthing Design
Earthing design for a new 400 kV onshore substation serving an offshore wind farm — CDEGS soil resistivity analysis, EPR and touch/step voltage assessment.
Northern Powergrid — BESS Integration Policy
NIA-funded policy development for large-scale BESS integration on distribution networks, including aggregated disturbance analysis and a DIgSILENT PowerFactory assessment tool.
Stoneshollow / Doverdale / Langford — G99 Studies
Simultaneous delivery of G99 Type D compliance packages, P28 assessment and HV cable sizing for three 49 MW hybrid solar and BESS sites at 132 kV.
Broxburn & Cathkin — SSO Studies
Sub-synchronous oscillation studies for two 49 MW BESS sites at SSEN 33 kV, challenging NESO’s initial guidance and agreeing a practical methodology with the regulator.
