Energy Engineering & Decarbonisation

Lean Energy builds the future of clean power. We use advanced tools – SoHUBS, HOMER Pro, EnergyPlus & Python programming –to analyse energy use, design solar-battery systems and optimise performance. We also tackle long-term power system planning for generation and transmission, integrating policy and engineering into simple, high-impact decarbonisation plans that cut costs and accelerate net-zero.
