TANZANIA ELECTRIC SUPPLY COMPANY LIMITED “We light up your life” TERMS OF REFERENCE PROVISION OF CONSULTANCY SERVICES FOR PROJECT MANAGEMENT AND SUPERVISION OF THE PROCUREMENT, DESIGN AND CONSTRUCTION OF TRANSMISSION SYSTEM INFRASTRUCTURES FOR P163752 - TANZANIA-ZAMBIA TRANSMISSION INTERCONNECTOR (TAZA) PROJECT July, 2021 1 Tanzania – Zambia Transmission Interconnector Project (TAZA) Project Management and Supervision Consultancy Services Terms of Reference 1. BACKGROUND The Tanzania – Zambia Transmission Interconnector Project (TAZA), involves the construction of a 400 kV double circuit transmission line and associated substations from Iringa through Tunduma to Sumbawanga with a 4 km spur from Tunduma Substation to the border with Zambia. The TAZA project will extend the Tanzania 400 kV transmission backbone to interconnect the transmission grids of Tanzania and Zambia to create the first high voltage link between the Eastern Africa Power Pool (EAPP) and the Southern African Power Pool (SAPP) for bi-directional regional power trade. It will also strengthen the capacity of TANESCO to become an operating member of SAPP, and to actively participate in intra- and inter-pool power trade among EAPP and SAPP member countries. In addition, the Project will advance regional integration between Eastern and Southern Africa, while accruing tangible economic benefits to Tanzania through enhanced power supply options and increasing revenues from power trade. 1.1. Overview of the proposed Transmission Infrastructure Extension The project, which is financed by the International Development Association (IDA); Agence Française de Development (AFD), and the European Union (EU), involves the construction of approximately 624km of 400 kV Iringa-Kisada-Mbeya-Tunduma-Sumbawanga (IKMTS) double circuit transmission lines and the associated substation works at Iringa, Kisada, Mbeya, Tunduma, and Sumbawanga. Further, an approximately 4km 330kV double circuit transmission line (constructed for 400kV but energized at 330kV) will be constructed from Tunduma substation to the Zambia border. The 400/330kV Tunduma substation, which is proposed to have three (3) 400/330kV autotransformers and associated switchgear will be financed separately from the rest of the project through the EU grant. The EU funding will also finance the 4km 330kV transmission line (constructed for 400kV but energized at 330kV) to the border with Zambia. The expected project works contracts (or lots) are as indicated below: Lot 1: Construction of approximately 106km 400kV Double Circuit Overhead Transmission line from Iringa to Kisada. Lot 2: Construction of approximately 185km 400kV Double Circuit Overhead Transmission line from Kisada to Mbeya. Lot 3: Construction of approximately 122km 400kV Double Circuit Overhead Transmission line from Mbeya to Tunduma. 1 Tanzania – Zambia Transmission Interconnector Project (TAZA) Project Management and Supervision Consultancy Services Terms of Reference Lot 4: Construction of approximately 203km 400kV Double Circuit Overhead Transmission line from Tunduma to Sumbawanga. Lot 5: Upgrade of the existing 220/33kV Iringa substation to 400/220/33kV and construction the proposed 400/220/33kV Kisada substation. Lot 6: Construction of the proposed 400/220/33kV Mbeya substation and 400/220/66/33kV Tunduma substation. Lot 7: Construction of the proposed 400/220/33kV Sumbawanga substation. Lot 8: Construction of the proposed 400/330kV Tunduma substation and the 4km 330kV double circuit transmission line (constructed at 400kV but energized at 330kV) to the Tanzania-Zambia border. Note: All the design, manufacture, testing, supply, erection and commissioning of the facilities included in the eight (8) lots above shall be the responsibility of the contractor(s). 2. OBJECTIVES The proposed 400kV Iringa-Kisada-Mbeya-Tunduma-Sumbawanga (IKMTS) transmission system infrastructure investments are intended to increase the power transmission capacity to the southern regions of Tanzania and to interconnect the Tanzanian power system with Zambia thereby making Tanzania an operational member of the Southern African Power Pool (SAPP). The interconnection of the Tanzanian and Zambian power systems will also enable power trading between SAPP and EAPP member countries. The proposed transmission infrastructure investments will also provide evacuation facilities for planned future generation plants within the project area, which will in turn lead to improvements in power quality, efficiency, and reliability in the southern regions of Tanzania. 2.1. Objective of the Consultancy Service The objective of the consultancy service is to provide construction supervision, implementation monitoring and contract management of the proposed IKMTS transmission system infrastructure investments as Owner’s Engineer to ensure compliance with the contractual requirement (technical specifications and the Environmental and Social Management Plan (ESMP)) and relevant TANESCO codes, quality investments, and timely implementation of the project investments to meet the project’s overarching objectives. 2.2.
