Lesotho seeks design, supervision of Polihali Dam, studies of 1,200-MW Kobong Pumped-Storage, conventional hydro

The Lesotho Highlands Development Authority (LHDA) seeks design and supervision of Polihali Dam, economic studies and development arrangements for the 1,200-MW Kobong Pumped-Storage project, and feasibility studies for conventional hydropower projects in the Lesotho Highlands Water Project (LHWP). Responses to two solicitations are due August 10 and September 14.

LHWP entails construction of dams and tunnels for storing, diverting and controlling water of the Senqu/Orange River and its tributaries to deliver water to South Africa, to generate hydropower in Lesotho and to undertake related developments. Phase 1 included construction of Katse and Mohale dams, the 72-MW Muela hydropower project and associated tunnels.

South Africa’s Cabinet agreed in 2008 to invest US$712 million in LHWP Phase 2, which includes construction of Kobong Pumped-Storage project, Polihali Dam as upper reservoir for Kobong, a Polihali-Katse transfer tunnel, roads and associated environmental and social programs.

LHDA took bids in February and March for services to implement several portions of Phase 2. As a result it awarded a contract to Maleka, Ntshihlele, Putsoa Joint Venture for 8 million maloti (US$648,397) for demarcation of Polihali Reservoir. It awarded two other contracts totaling about 32 million maloti (US$2.6 million) to:

  • SMEC-FMA Joint Venture to upgrade the Polihali northeast access road; and
  • Jeffares & Green (Pty) Ltd. and GWC Consulting Engineers for evaluation, optimization and site supervision of geotechnical investigations for Polihali Dam and Polihali-Katse Transfer Tunnel.

LHDA now reissues an invitation for pre-qualification for design and construction supervision of Polihali Dam and appurtenant works. Pre-qualification documents may be obtained until July 28, with a mandatory pre-qualification meeting August 4 and responses due September 14.

Pre-qualification documents may be obtained at no cost from the Phase 2 project Internet site at http://www.lhda.org.ls/phase2/tenderbulletin. They also may be obtained by July 28 for 1,000 maloti (US$81) deposited in the LHDA bank account from Lesotho Highlands Development Authority, LHWP2 Project Management Unit, 10th Floor, Lesotho Bank Tower, Kingsway St., Maseru, Lesotho.

More studies of 1,200-MW Kobong Pumped-Storage, conventional hydro

LHDA also invites expressions of interest by August 10 from consultants to complete economic studies and development arrangements for the 1,200-MW Kobong Pumped-Storage project and feasibility studies for conventional hydropower projects in the Lesotho Highlands Water Project.

Work on the Kobong portion of the tender is to include due diligence review of the existing pumped-storage project feasibility study, identification of issues, technical review of alternative pumped-storage schemes, electricity load studies and economic evaluation. If the project is found to be viable, additional work includes economic evaluation within the Southern Africa Power Pool, institutional viability, a power purchase agreement, financing requirements and a geotechnical site investigation.

Work on the conventional hydropower portion of the tender includes studies of potential modifications or additions to Phase 1 works, including the 72-MW Muela hydro project, as well as greenfield sites where new hydropower could be developed, and development of a bankable feasibility study.

The work is expected to require two years beginning in 2016.

Expression of interest documents may be obtained at no cost from the Phase 2 project Internet site at http://www.lhda.org.ls/phase2/tenderbulletin.

Expressions of interest are due by 2 p.m. August 10 in person, by mail or by e-mail, labeled “Expression of Interest for Professional Services for Phase II Hydropower Feasibility, Further Studies, Contract LHDA No. 3010.”
