STE S.A. – TTP – 400 kV Transmission System Backbone

The Temane Transmission Project (TTP) is Phase 1 of Mozambique's strategic Tete–Maputo transmission backbone and a core component of the wider Temane Regional Electricity Project (TREP). The project was implemented by Sociedade Nacional de Transporte de Energia, S.A. (STE), a wholly owned subsidiary of Electricidade de Moçambique E.P (EDM).

Prior to founding EnergyBridge Group (EBG), members of EBG's current leadership team held senior project, technical, construction and sustainability roles within STE and contributed to the project across its lifecycle, from feasibility, development and financing through procurement, construction, commissioning and operational handover.

The TTP infrastructure comprises:

  • 563 km of 400 kV single-circuit transmission line
  • 2 × 25 km of 400 kV double-circuit transmission line
  • Four new 400 kV substations: Pambara, Chibuto, Matalane and Maputo

The transmission system enables evacuation of power from the 450 MW Central Térmica de Temane (CTT) Independent Power Project (IPP) and establishes strategic backbone capacity for future large-scale gas, hydro and renewable generation projects in Mozambique.

Complementary grid reinforcement development works included:

  • 28 km, 110 kV Pambara–Temane transmission line extension
  • 60 km, 275 kV Dzimbene–Chibuto transmission line extension

Core Services Delivered:

  • Led and supported feasibility, development, funding support, procurement, construction oversight, commissioning and operational handover of one of Mozambique's largest infrastructure projects undertaken since independence in 1975

  • Supported the structuring and mobilisation of major concessional and grant financing, including a US$300 million IDA grant from the World Bank Group and approximately US$150 million of complementary concessional financing involving the African Development Bank, OPEC Fund for International Development and Islamic Development Bank, together with additional Norwegian grant support.

  • Directed procurement and construction oversight across six major EPC packages, including:

    • 1: Four new 400/230/110/66 kV substations
    • 2: Two 150 MVAr STATCOM installations
    • 3: 14 single-phase step-down transformers (400/230/110/66 kV) & 15 single phase reactors
    • 4: 25 km double-circuit 400 kV transmission line
    • 5: 220 km single-circuit 400 kV transmission line
    • 6: 340 km single-circuit 400 kV transmission line

  • Oversight of Owner's Engineer and EPC contractor performance across technical, programme, quality, interface and delivery requirements.

  • Led and supported implementation of environmental and social requirements aligned with World Bank Environmental and Social Standards and IFC Performance Standards (PS1–PS8), including Resettlement Action Plan (RAP) implementation as a key lender and project-delivery requirement.

  • Managed project-on-project risk across the critical transmission–generation interface within TREP, ensuring schedule alignment and quality coordination between TTP and the 450 MW Central Térmica de Temane (CTT) Independent Power Project (IPP).

    • Supported institutional capacity building across transmission project management, development, procurement, construction, commissioning and long-term network operations.
