Infrastructure advisory company Osmotic Engineering Group (OEG) has appointed Andrew Johnson as Chief Financial Officer, formalising a strategic leadership role that reflects the company’s strategy for expansion and growing project portfolio.
Johnson, a mechanical engineer with an MBA (cum laude) from Stellenbosch University, has eighteen years of international experience in energy advisory, power generation, renewable energy, and energy storage. His career spans senior technical, managerial, and advisory roles across Africa, Australia, Asia, and the United Kingdom.
Johnson joined OEG at its inception in 2020. He has since served as Director: Energy, leading technical delivery on major assignments for Anglo American, Pele Green Energy, Stellenbosch Municipality, the IPP Office, MTN, Discovery Green, Tronox, various other mining clients and development finance institutions.
His portfolio included technical leadership on feasibility studies, energy modelling, EPC and PPA development, owner’s engineer services, and high-level advisory on renewable energy strategies and large-scale procurement programmes.
Johnson says the formalisation of the CFO role marks an important step in OEG’s evolution. “When we started the venture, we came from technical backgrounds and had to learn to run a business. Over time, each of us gravitated towards the areas where we added the most value, and I found myself taking responsibility for the accounting and finance portfolio. As we enter the next five-year cycle, it is the right time to formalise that structure.”
He emphasises the importance of strong financial governance to support OEG’s expansion into new jurisdictions. “Our projects are getting bigger and more complex. Clients want to know they are working with a consulting firm that has established systems and structured management. My role is to ensure sustainable growth, manage financial risk, and support the long-term vision of the company.”
Johnson adds that OEG will also explore external investment as part of its future strategy. “We are preparing the company for valuation and potential investment that will help drive the next phase of growth,” he notes. His appointment reinforces OEG’s commitment to robust financial systems, strategic expansion, and long-term sustainability.
