We're a team of engineers [kWh.Systems] providing engineering services and solutions in the fields of renewable energy, electrical, and electronics for more than a decade.

When energy development projects move from concept to engineering validation, the simulation models either support investment decisions or create expensive delays. I build the technical models that do not create delays. I am an Energy Systems Engineer and Power Systems Analyst with specialized depth in renewable energy integration, grid-scale storage design, and wind energy performance modeling. My deliverables are built to be technically defensible in front of investors, lenders, and grid operators. WHAT I DELIVER — Power systems load flow, fault analysis, and protection coordination studies (ETAP) — Solar PV energy yield modeling and bankable production reports (PVSyst) — Wind farm energy yield assessment and turbine aerodynamic performance analysis (QBlade, PyWake) — Grid-scale and hybrid energy storage feasibility studies with full LCOS and financial modeling — Advanced gravity-based and kinetic storage system design and performance simulation — Renewable energy system optimization and control modeling (MATLAB/Simulink) — Life cycle and environmental impact assessment for energy infrastructure (openLCA) SOFTWARE STACK ETAP · PVSyst · QBlade · PyWake · MATLAB/Simulink · Python · openLCA · & Many more. SELECTED PROJECT EXPERIENCE Designed and modeled a 50 MW wind-integrated Underground Gravity Energy Storage system delivering 50 MWh/day. Full techno-economic output: LCOS PKR 16.09/kWh, NPV PKR 1,022M, IRR 23%, payback 4.4 years — investment-grade analysis. Currently engaged as renewable energy systems consultant for a startup. QA engineering on PowerChina's 200 MW wind power project in Oman — EPC by Huadong Engineering, JV between OQ Alternative Energy and TotalEnergies. WHO I WORK WITH EPC contractors, independent power producers, energy consultancies, research institutions, and development finance organizations that need technically rigorous simulation outputs — not templates. If your project requires defensible energy modeling, grid compliance verification, or investment-grade feasibility analysis, send me the scope.

Worrying about your facility's electrical safety — or looming OSHA deadlines — shouldn't keep you up at night. I help US industrial and commercial clients protect their workers, eliminate safety risks, and achieve full NFPA 70E / IEEE 1584 compliance without the stress. What I Deliver: Arc Flash & Electrical Safety Studies Reduced arc flash incident energy by 35% for a 480V industrial facility. By redesigning protection coordination settings and optimizing relay trip times in ETAP, I helped the client significantly lower their hazard risk. Achieved 100% NFPA 70E and IEEE 1584-2018 compliance for a 12-bus commercial facility. I conducted full short circuit, coordination, and arc flash studies in ETAP, securing final hazard analysis report acceptance. Delivered complete arc flash warning label datasets for 50+ electrical panels. I executed the full equipment inventory, bus modeling, and incident energy calculations in EasyPower, leading to successful client sign-off and deployment. Protection Coordination & Short Circuit Studies Eliminated costly manufacturing downtime. I resolved a facility's issue with recurring nuisance trips (3x/month) by analyzing their operations logs and reconfiguring overcurrent relay coordination curves in SKM PowerTools. Reduced fault clearance time by 28% across a 15-bus radial distribution network. By analyzing ETAP time-current curves (TCCs), I optimized fuse-relay coordination and set highly selective trip zones. Completed short circuit duty evaluations for 6 switchgear assemblies rated up to 65kA. I ran ANSI/IEC fault current studies in ETAP and cross-referenced manufacturer interrupting ratings to verify equipment withstand capabilities. Load Flow & Power Quality Studies Improved system voltage profiles by 12% across a 33kV distribution feeder. After conducting pre- and post-load flow simulations in ETAP, I modeled and recommended reactive power compensation via strategic capacitor bank placement. Identified and resolved 4 overloaded cable segments in a 2MW industrial facility. I performed detailed load flow and cable sizing analysis in SKM PowerTools to provide accurate ampacity derating reports. Reduced transformer loading from 112% to 87% of rated capacity. Using PowerWorld load flow output reports, I safely redistributed loads and modeled an optimized single-line diagram layout. CAD & Engineering Documentation Delivered 100% as-built accurate single-line diagrams for a 7-building campus. I drafted detailed SLDs in AutoCAD Electrical with full equipment tagging and feeder schedules, securing prompt engineering review approval. Streamlined the engineering process, reducing drawing revision cycles by 40%.
