In a tersely worded press statement that did not state the shutdown’s exact cause or when gas supply is expected to be restored, the operator of Jubilee oil field from where the gas comes said: “We are working hard to reinstate gas export as a matter of priority”.
In January a faulty compressor was reported to have similarly hindered gas supply from the Jubilee Field.
The compressor works in a similar fashion to pumps; it increases the pressure of the gas by reducing its volume and transports it through a pipe.
Two thermal units of the VRA at Aboadze were running on about 50million standard cubic feet of gas from the Ghana Gas processing plant before the shutdown.
While sector managers are shying away from speaking to the issue directly, a source told the B&FT the gas from the Jubilee Field has actually been absent from the VRA’s plants “for some time now”.
Ideally, when gas is absent VRA plants that have dual fuel capacity are supposed to run on light crude oil. The B&FT could not obtain from sector managers what the implications of the shutdown would be for power generation in the meantime.
Various challenges have hindered the delivery of a potential 120 million standard cubic feet of gas a day from the FPSO Kwame Nkrumah to the processing plant at Atuabo.
In January, Tullow oil indicated that it was in a position to supply up to the 120 million standard cubic feet of gas per day, but said power producers are unable to absorb all.
“Tullow is currently able to supply up to 120 mmscf of gas per day and makes this volume of gas available every day. The volume requested by our customers has been well below this volume, and so far has consistently been below their own requests.”
