The Central Termica de Temane, also known as the Temane thermal power plant, is a 450MW gas-fired power project being developed in the Inhambane province of Mozambique.
A consortium of Moz Power Invest (MPI) and Sasol New Energy is developing the project with an estimated investment of approximately £542m ($760m). MPI comprises Electricidade De Moçambique (EDM), and Temane Energy Consortium, which further consists of Globeleq and EleQtra as the lead developers of the project.
The development partners took a final investment decision (FID) on the project in February 2021, while the construction works are scheduled to be started in the third quarter of 2021.
Expected to commence operations in the fourth quarter of 2023, the Central Termica de Temane gas-fired facility will be complemented by the Temane-Maputo Transmission Project (TTP) that will involve the construction of 563km of 400kV single-circuit transmission lines along with three new substations.
Location and site details
The Central Termica de Temane gas-fired power project is located in the Temane area, in the Inhassoro district, Inhambane Province, in southern Mozambique.
The project site lies in close proximity to the existing gas deposits and a central processing facility (CPF), approximately 8km away from the Govuro River.
Central Termica de Temane plant make up
The Central Termica de Temane gas-fired power block will be equipped with a Siemens SGT-800 gas turbine, a steam turbine, and a heat recovery steam generator (HRSG) for a total power output of 450MW.
The project will also involve air-cooled condensers, continuous emission monitoring system (CEMS), a switchyard, transformers, raw water treatment system, and a by-pass stack.
Infrastructure facilities
The other infrastructure facilities for the Central Termica de Temane power project will include a water pipeline from the borehole to the plant site, a 1.8km-long, buried gas pipeline between the central gas processing facility and the power plant, access roads, construction camp, and contractor laydown areas.
It also involves the construction of a temporary jetty, temporary bridges, an administration building, workshops, warehouses, a waste treatment facility, and other ancillary facilities.
Power evacuation
The electricity generated by the Central Termica de Temane power plant will be evacuated into the grid through a 25km-long, 400kV single-circuit power transmission line connecting the Vilanculos Substation.
Natural gas supply
The Central Termica de Temane power plant will receive gas supply from the Pande-Temane gas fields, operated by Sasol and Empresa Nacional de Hidrocarbonetos (ENH), via a central gas processing facility.
Power purchase agreement
The electricity output of the Central Termica de Temane power plant will be sold to Electricidade De Moçambique (EDM) under a 25-year tolling agreement.
Financing
The Central Termica de Temane power project is being funded through approximately £154.16m ($200m) of development finance from the US International Development Finance Corporation (DFC) approved in September 2020.
It will also receive a credit facility of approximately £38.54m ($50m) through the OPEC Fund for International Development (OFID).
The project is also expected to receive funding from the International Finance Corporation (IFC), World Bank, Norwegian Development Fund, African Development Bank, and the Islamic Development Bank.
Contractors involved
TSK was awarded a contract valued at approximately £274.41m ($363.31m) by Globeleq Energy Group for the construction of Temane thermal power project in December 2020.
Siemens is responsible for the supply of gas turbines, along with associated equipment for the project.
Golder Associados Moçambique was contracted for the preparation of the environmental and social impact assessment (ESIA) of the project, while Norconsult was engaged by EDM for technical advisory services.
Engineering consultancy firm Royal HaskoningDHV provided independent environmental and social advisory services to IFC and DFC for the project.
