Pathmanathan (Pat) Naidoo, Ph.D., Pr.Eng, is the Resident Engineer with Pat Naidoo Consulting Engineers, a private, independent and professional electrical engineering company, recently established in the Republic of South Africa.   Dr Naidoo comes directly to the private sector from the post of Chief Executive of the Western Power Corridor Company of Southern Africa and Senior General Manager of Eskom, South Africa.

Dr Naidoo had spent 26 years with Eskom, the vertically integrated national electricity utility of South Africa.  He commenced work as an engineer in training and progressed through the company to executive leadership. During his tenure as Senior General Manager he led the Transmission Group of Eskom South Africa and directly managed Power System Operations, Eskom Power Pool Energy Operations, Real Time Control of the South African National Grid, Regional Management of the Southern African Power System and Cross Border Energy Trading.

He served Eskom as a member of the various Company, Group and Divisional Committees such as Operations, Procurement, Investment, Finance, Audit and Human Resources. He led Eskom’s participation at The Southern African Power Pool (SAPP), a regional gathering of national utilities and at The Union of Power Producers and Distributors of Africa (UPDEA), a continental gathering of national utilities.

In later years, he was seconded to the Office of the Chief Executive of Eskom as Technical Director of the Mozambique Transmission Company (MOTRACO – A Joint Venture of Eskom South Africa, SEB of Swaziland and EDM of Mozambique), as Special Projects Leader for the Refurbishment of Eskom’s Large Power Transformers, as Specialist Consultant of Eskom’s 765 kV Transmission Technology for Commercial Consulting Contracts for Power Grid Corporation and National Thermal Power Corporation of India and State Grid of China, as Specialist Consultant of HVDC Technology for Eskom and the Southern African Power Pool and  as Chief Executive of the Western Power Corridor Company (PTY) LTD (WESTCOR), a five country joint venture incorporated in the Republic of Botswana.

WESTCOR was equally owned by the Governments of Angola, Botswana, Democratic Republic of Congo, South Africa and Namibia and the work involved conceptual, prefeasibility and feasibility studies for  large scale hydro electric power generation in the Congo River and the transportation of the bulk electrical energy onto the national grids of the participating countries and the rest of Southern Africa.  In the feasibility stage of the studies the shareholders stopped the project due to unforeseen changes in the founding agreements.

In 1994, Dr Naidoo received The Young Achievers Award of the South African Institute of Electrical Engineers and in 2010, The Ann van Dyk Applied Research Award from the Da Vinci Institute of Technology Management. Dr Naidoo currently chairs the Power and Energy Society of IEEE SA Section. Dr Naidoo is fluent in English.

Notable Contributions as a Member of the Operations and Management Committee

  • Established the co-ordination centre in Harare, Zimbabwe.  Appointed the first co-ordination centre manager, the first understudy engineer and the first office staff.  Funding was provided for by USAID.  The first manager appointed was the past Executive Director of the New York Power Pool.
  • Developed and established the short term energy market for opportunity trading of electrical energy between interconnected members.  The average annual trade was USD 4m.  The market continues to function.
  • Developed the power pool plan to show future integration of new supply options, new transmission interconnections and new demand profiles for the SADC region.
  • Prepared the founding agreements for  the new regional cross border joint venture company : The Western Power Corridor Company (PTY) LTD.


The Mozambique Transmission Company

Notable Contributions as Technical Director

  • Planned, designed, built and operated a new  400 kV transmission system to supply the new BHP Billiton Mozal Aluminium smelter in the port city of Maputo; to interconnect with the Mozambique and Swaziland National Grids at Maputo and Edwaleni sites, respectively.  The power system was developed in two stages; involving 2 x 300 km 400 kV power transmission lines; 2 x 400/132 kV substations and 2 x 300 MVar 400 kV series power capacitors.
  • Maputo substation received 3 x 500 MVA power transformers and Edwaleni Substation received 2 x 125 MVA power transformers
  • Project Management results included costs management to below budget and final commissioning ahead of schedule; savings returned to shareholders.
  • Fault free project commissioning and loading of smelters to full capacity; 900 MW.
  • Fault free integration with the Mozambique and Swaziland national grids

At full load, a new 500 MVA power transformer developed severe vibrations; prepared contingency plans but eventually operated and repaired the unit on site and within a tight schedule of 48 hours.  Operation was successful and the unit remains in service to date.



Notable Contributions as Chief Executive

  • Established the project office and concluded the conceptual first pass study, the pre-feasibility study and the business plans for the 5000 MW Inga 3 hydro electric power station on the Congo River.  The design employed was run of river technology for a minimum footprint at the environmentally fragile site alongside the mighty Congo River.
  • Developed the power transmission plans for very long distance bulk power transfers in association with country to country power delivery and transmission integration with each national grid.  New 800 kV EHVDC designs were prepared for the 3000km, 3000 MW power transfers whilst new 400 kV transmission lines provided for country to country national grid integration.
  • Developed the company business plan showing an annual revenue flow of USD 2,1 b for the sale of 5000 MW at unity load factor and at world’s lowest tariff of US 5 c/kWh.  With an estimated USD 8b capital expenditure, the payback period was planned to be less than a decade.
  • Project was aborted by shareholders when unforeseen changes were proposed to the founding agreements.  Early set back but managed carefully to the satisfaction of all shareholders with virtual no financial loss to any party.
