DERM Group signed the USD 20.16 million berth electrical-power works contract in October 2024; the planned June 2026 end has passed without public completion or acceptance evidence

Project sources

Tanzania Ports Authority signed World Bank project contract TZ-TPA-310413-CW-RFB with DERM Group Company Limited on 31 October 2024 for design, supply, installation and commissioning of electrical power at Dar es Salaam Port's berths 1-7 and RoRo berth. The World Bank contract record reports USD 20,159,532.34, and the July 2025 implementation report said installation works were ongoing. The planned implementation window ended in June 2026, but no cited source confirms commissioning, acceptance or defects closeout.

Project anatomy

Contract scope and delivery roles

Client / authority
Tanzania Ports Authority under the World Bank-financed Dar es Salaam Maritime Gateway Project
Delivery parties
DERM Group Company Limited - design, supply, installation and commissioning contractor, Supervision consultant, cable suppliers, transformer suppliers, switchgear suppliers and installation subcontractors - not identified in the cited award dataset
Contract route
World Bank project P150496 used a prior-review Request for Bids for works contract TZ-TPA-310413-CW-RFB. The supplier-contract dataset records the 31 October 2024 signature, DERM Group Company Limited and USD 20,159,532.34 committed amount. Public records reviewed do not disclose the bid field, final contract amendments, supervision award or subcontract chain.
Execution window
The 2024 restructuring paper planned electrical installation and supervision from July 2024 through June 2026. It allowed for at least eight months to import cables, transformers and machines, at least one year for installation, testing and commissioning in a live port, and a 12-month defects-liability period that could extend beyond the World Bank closing date. The October 2024 signature came after the planned start assumption.
Works package
The contract title covers design, supply, installation and commissioning of electrical power at berths 1-7 and the RoRo berth. The restructuring paper also discussed a separate power connection from the endpoint at Ilala Substation to the port main substation as a possible variation. Public award data do not disclose cable lengths, voltage levels, transformer ratings, substations, switchgear quantities, civil trenches, control systems or operational load-testing criteria.
Marine interfaces
Installation must be sequenced around live berth operations, cargo access, buried services, crane and terminal loads, vessel movements and the completed berth structures. Commissioning depends on the upstream grid connection, protection coordination, earthing, cable testing, energisation permits, outage planning and acceptance by TPA. None of those technical closeout gates is confirmed by the signed-contract record alone.
Commercial evidence boundary
The USD 20.16 million amount belongs to the DERM electrical works contract, while the broader Dar es Salaam Maritime Gateway Project is a separate multi-contract programme. Civil deepening and strengthening of berths 1-7 and the RoRo terminal were reported complete by September 2024. Electrical completion, any Ilala connection variation, supervision, final account and defects obligations remain distinct commercial questions.

World Bank reported electrical installation under way

The project implementation report said procurement of the electrical power-supply installation contract was complete and works were ongoing; it did not report energisation, commissioning or acceptance.

TPA signed the berth electrical works contract

The World Bank supplier dataset named DERM Group Company Limited and reported USD 20,159,532.34 for design, supply, installation and commissioning at berths 1-7 and the RoRo berth.

Restructuring fixed a June 2026 implementation target

The World Bank allowed a 24-month installation and supervision window, long equipment lead times and live-port commissioning, while recognizing that defects obligations could continue beyond closing.
