RE & Storage Advisory · in motion

Utility-scale renewables and storage live or die on the quality of early engineering decisions. Our advisory desk combines resource analytics, detailed engineering and grid expertise so every recommendation is bankable — not just theoretical.

We support developers, industrial off-takers and investors across feasibility studies, BESS & RE detailed design, dispatch modelling, technology selection, owner's engineering and technical & financial due diligence — across solar, wind, small hydro and storage. Our modelling desk advises on Round-The-Clock (RTC) and Firm & Dispatchable RE (FDRE) supply — optimising solar-wind-hydro-storage portfolios against demand profiles, transmission constraints and bid requirements.

Beyond design, we stay accountable through delivery: as Project Management Consultant (PMC) we manage schedule, cost, quality and contractors on the owner's behalf, and as Independent / Lender's Engineer we provide the impartial technical oversight that lenders and investors rely on from construction through operations.

Advisory by technology

RE & Storage Advisory across every clean-energy technology

Each technology has its own physics, supply chain and regulatory regime. Pick one to see exactly how we advise on it.

Solar

From 1 MWp captive rooftops to 500 MWac park allocations, our solar desk turns irradiance into bankable yield. We model P50/P75/P90 generation with real soiling, clipping and grid-curtailment assumptions — not brochure numbers.

What we do

  • GHI/DNI resource assessment using satellite + ground-station reconciliation
  • DC:AC ratio, tracker vs fixed-tilt and bifacial gain optimisation
  • String/inverter architecture, layout, shading and cable-loss engineering
  • DPRs, Solar-GIS-grade yield reports and lender's technical reviews

Key engineering considerations

  • Land aspect ratio, slope and flood levels drive tracker economics
  • ALMM/DCR compliance and module degradation warranties affect tariff
  • Evacuation voltage and bay availability often fix the real plant size

Typical deliverables

  • Energy yield report (P50/P90) with loss diagram
  • Plant SLD, layout & BoQ for procurement
  • Solar DPR and bankability memo
