Phase 1A of liquefied petroleum gas (LPG) fueled – Bridge power project being built in Tema, Ghana is set to start delivering 142MW of power by end of January.
The 400MW – LPG fueled combined-cycle power plant, is the first of its kind to be undertaken in Africa, and the biggest of its kind in the world.
The US$953m power plant is being built in two phases. The first stage having a capacity of 194MW and the second having a capacity of 206MW.
Stage one has been subdivided into 1a and 1b with capacities of 142.5MW and 51.5MW respectively. Stage 1a will be an open cycle configuration that is installed with five GE TM2500+ generator sets, including five LM 2500 gas turbines.
The project is being undertaken by three investor institutions – known together as Early Power Limited comprised of multinational consortium Endeavor Energy, General Electric (GE) and Sage Petroleum Limited.
Stage 1b will comprise one GE steam turbine generator to enable combined-cycle operation.
Additionally, five once-through steam generators, one air-cool condenser, on-site LPG storage and transportation pipeline and other balance of plant equipment, will be added during the stage.
This stage has also been subdivided into 2a and 2b, with capacities of 160MW and 46MW respectively.
Stage 2a is to include the installation of four GE LM 6000 PC Sprint gas turbines in open cycle configuration. Stage 2b will add one GE steam turbine generator to enable combined-cycle operation.
Stage 2b will also add four heat recovery steam generators, one air-cool condenser and other balance of plant equipment.
A 9.4km-long LPG pipeline with a diameter of 12in will be built from the TEMA jetty to the Tema oil refinery. The pipeline will enable LPG to be transferred to a new purpose-built storage system at the refinery and will ensure there is LPG supply to the power plant throughout the year.
A 1.1km-long water pipeline, raw and demineralized water storage tanks, diesel tanks with capacity of 30m³, main stacks, a demineralization plant, and administration and warehouse facilities will also be part of the plant.
The project will use imported LPG as the primary fuel, and diesel as the secondary fuel during the first five years of operation. Natural gas is expected to become available to serve as the primary fuel, and LPG will become the secondary fuel later.
The project, according to its developers, will enhance the country’s energy security as the plant is capable of being fueled by Liquefied Petroleum Gas (LPG), natural gas or diesel, and will be responsible for importing its own fuel.
