Electrical engineer with 14+ years of progressive responsibility in transmission grid operations and planning, culminating in a Principal Engineer role managing substation O&M across 7 sites for Ghana’s national grid op- erator (GRIDCo). Since relocating to Germany, has applied that operational depth to renewable grid-connection assessment (VDE-AR-N-4110/4120) for wind and solar parks at SH-Netz (E.ON), and completed an MEng in Sus- tainable Energy & Development at Europa-Universität Flensburg (2026), including quantitative modeling of BESS and renewable integration. Combines hands-on HV substation expertise with current German grid-connection practice.
