COUNTRY: Southern African Power Pool region

NAME OF PROJECT: Southern African Power Pool Program for Accelerating Transformational Energy

Projects Grant No.: H9890

Assignment Title: Zambia Tanzania Interconnector Project: Consulting Services for Final Design and Bidding Documents

The World Bank is preparing a Program with the Southern Africa Power Pool (SAPP) to help accelerate preparation of priority regional power generation and transmission projects in the region of the Southern African Power Pool. The Program Development Objective is “to facilitate the preparation of priority regional energy projects in the Southern African Power Pool region”.

Objectives of consultancy assignment

This assignment is associated with Zambia – Tanzania Interconnector Project (ZTIP) includes the following objectives;

• Review the preferred line route provided by ZESCO and the AECOM study reports and recommend any changes to the same. This shall be in collaboration with ZESCO with full cognisance of the existing ESIA studies and the ESIA update under preparation, taking into account consolidated impacts of various alternative routes.

• Carry out geotechnical investigations and utilise the output of the investigation in the preparation of procurement documents.

• Prepare designs (including specifications, drawings, bills of quantities, etc) and tender documents for International Competitive Bidding for the ZTIP up to contract award in reference to available feasibility study documentation, The geotechnical investigation results and environmental and social management requirements.

Project history

In 2014, the Governments of Zambia, Kenya and Tanzania signed a tripartite IGMoU to carry out feasibility studies and implement the Zambia – Tanzania – Kenya (ZTK) Interconnector. Consequently, complete Techno-economic feasibility and ESIA studies were carried out by AECOM and WSP respectively in the period 2014 to 2017 under the co-ordination of NELSAP, and Office for Promoting Private Power Investment (OPPPI) Zambia. The key project preparation milestones are illustrated in chronological order below:

These ZTK studies were financed from the grant provided by the Government of Norway, the European Union and COMESA. In 2016, to complement then ongoing AECOM and WSP studies, a complementary study was also carried out by RICARDO to specifically assess the wheeling arrangements, possible trade volumes and mechanisms, legal requirements and technical impact assessments that were not fully covered under the AECOM study ToRs.

Furthermore, during the AECOM study implementation, ZESCO committed some transmission projects to enhance the power transfer capacity to the northern part of Zambia, taking into consideration the ZTK preliminary studies recommendations. With the aforementioned developments, the AECOM study therefore recommended that the ZTK is to be developed in two phases on the Zambian section:

Phase one for the ZESCO committed projects, which scope involves establishment of a single 330kV line from Pensulo through Mpika, Kasama and Nakonde to the Tanzania border and establishment of a second single 330kV line from Kabwe to Pensulo; and Phase two to ensure an n-1 500MW transfer capacity, which involves establishment of a second 330kV line from Pensulo through Mpika, Kasama to Nakonde.

Following the completion of the ZTK studies, the Southern African Power Pool (SAPP) and the Eastern Africa Power Pool (EAPP) engaged AURECON to carry out an operationalization study in 2018 under the SAPP Accelerating Regional Transformational Energy Projects (SAPP AREP) Program, funded by the World Bank. The AURECON study took a wide area view of the two power pools but focused on the details around the countries directly involved in coupling the two pools, particularly Zambia and Tanzania.

The AECOM, RICARDO and AURECON studies recommended that voltage support equipment is required on the ZTK transmission corridor between Pensulo and Nakonde to ensure reliable and secure power transfer through the Zambian section of the corridor and that a further study is required to optimise the DVSDs locations and sizes. The studies further recommended that a review of the Power System Stabilizer settings among SAPP/EAPP member countries is required. The AECOM Study recommended that with voltage support in the Pensulo – Nakonde Zambian section of the ZTK, a transfer capacity of about 530 MW and 458 MW for the Tanzania to Zambia and Zambia to Tanzania respectively were possible.
