LAHORE: Punjab Thermal Power Limited (PTPL) has initiated pre-qualification process for hiring of engineering consultant for testing and commissioning of 1,263 megawatts Combined Cycle Punjab Power Plant at Jhang.
The PTPL has floated an international tender for hiring of an engineering consultancy that would oversee the tests being performed as per power purchase agreement requirement and issue certificates on successful completion of those tests required for commercial operations to be achieved. Project documents indicate prequalification and hiring of successful engineering services consultant are expected to be complete by mid-August.
Documents show the project is scheduled to be commissioned in phases; with both gas turbines expected to achieve operation in simple cycle mode during the last quarter of 2018 whereas the plant would be commissioned in combined cycle mode in the last quarter of 2019.
Project documents highlight the Punjab government, through PTPL, was setting up a 1,263MW power plant near Trimmu Barrage, Haveli Bahadar Shah, Jhang, under independent power producer (IPP) regime. The PTPL had signed engineering, procurement and construction contract of the power plant with China Machinery Engineering Corporation (CMEC) on September 29, 2017.
As per schedule, the project would be ready for back feed by mid-August 2018. Availability of stable gas supply is expected by September 30 and simple cycle operations are expected to start by December 2018 or January 2019. Following detailed testing and commissioning the projected is expected to start commercial operations by November-December 2019.
The plant would primarily run on re-gasified liquefied natural gas (RLNG) whereas high-speed diesel (HSD) will be used as backup fuel.
The configuration of the plant comprises two gas turbines, two heat recovery steam generators and a steam turbine. The plant is being designed, manufactured and installed for continuous operation at base load and as well as at part loads.
It shall comprise components and systems built to international standards. Standardisation and interchangeability of equipment and parts shall be optimised. The plant would comply with all the applicable national and statutory codes. It would be designed for a lifetime of 240,000 operating hours over a period of 30 years.
The power generated through the project would be evacuated via 220KV transmission line that traverses about 35 kilometres from the site.
