Nearly 10 years and over P10 billion later, Morupule B – a 600 Megawatt coal fired energy plant that was envisaged to finish Botswana ‘s national power crises still can’t ship to full capability, forcing the nation to pay over P2 billion yearly in importation of energy from surrounding producer nations.
The newest quarterly report from Statistics Botswana, reviewing the nation’s energy era for the fourth quarter of 2021 has written off the progress made through the third quarter, reporting a quarter-on-quarter lower of 18.9 %, from an Index of Electricity Generation (IEG) of 137.7 through the third quarter of 2021 to 111.7, giving a transparent reflection that the nation takes 2 steps ahead and three steps backward so far as native energy era is anxious.
In the third quarter of 2021, electrical energy era had picked up, with a 14.6 % factors leap on IEG, from the Index of 120.2 through the second quarter of 2021. In bodily phrases, native electrical energy era had elevated by 14.6 % (73,723 MWH), from 505,313 MWH through the second quarter of 2021.Statistics Botswana had credited the rise to improved efficiency of Morupule A and B energy stations.
However in a setback over the last quarter of 2021 manufacturing of electrical energy regionally took a downturn, each on quarterly and year-on-year foundation, primarily due operational challenges at Morupule B. A year-on-year evaluation exhibits a lower of 9.3 % in IEG, in comparison with 123.1 recorded through the corresponding quarter in 2020.
The bodily quantity of electrical energy generated decreased by 9.3 % (48,278 MWH), from 517,627 MWH through the fourth quarter of 2020 to 469,349 MWH through the present quarter.
The quarter-on-quarter perspective exhibits that native electrical energy era decreased by 18.9 % (109,686 MWH), from 579,036 MWH through the third quarter of 2021 to 469,349 MWH through the interval below assessment. “This decrease was largely due to operational challenges at Morupule B power plant.” Said Statistics Botswana
A lower in native era means improve in importation, through the fourth quarter of 2021, the bodily quantity of imported electrical energy elevated by 16.7 % (77,716 MWH), from 465,701 MWH through the fourth quarter of 2020 to 543,417 MWH through the quarter below assessment.
Compared to the earlier quarter, electrical energy imported through the fourth quarter of 2021 elevated by 28.0 % (118,714 MWH), from 424,703 MWH through the third quarter of 2021 to 543,417 MWH.
Botswana imported 53.7 % of complete electrical energy distributed through the fourth quarter of 2021. Eskom, South Africa’s state-owned energy era outfit was as typical the principle supply of imported electrical energy at 40.6 % of complete electrical energy imports.
The Zambia Electricity Supply Corporation Limited (ZESCO) accounted for 22.0 %, whereas the remaining 17.0, 15.0, 4.0 and 1.4 % have been sourced from Electricidade De Mozambique (EDM), Southern African Power Pool (SAPP), Cross-border electrical energy markets and Nampower, respectively.
Cross-border electrical energy markets is a Statistics Botswana nomenclature referring to cities and villages alongside the border that are equipped with electrical energy immediately from neighbouring nations resembling Namibia and Zambia.
In phrases of distribution year-on-year evaluation exhibits that the quantity of distributed electrical energy elevated by 3.0 % (29,438 MHW), from 983,328 MWH through the fourth quarter of 2020 to 1,012,766 MWH through the present quarter.
The quarter-on-quarter comparability of distributed electrical energy exhibits a rise of 0.9 % (9,028 MWH), from 1,003,738 MWH through the third quarter of 2021 to 1,012,766 MWH through the assessment quarter.
Electricity generated regionally contributed 46.3 % to electrical energy distributed through the fourth quarter of 2021, in comparison with a contribution of 52.6 % throughout the identical quarter in 2020, a lower of 6.3 proportion factors.
The quarter-on-quarter comparability exhibits that the contribution of electrical energy generated to electrical energy distributed decreased by 11.4 proportion factors in comparison with the 57.7 %.
MORUPULE B CHALLENGES
The Morupule B challenge was adopted because the least value answer to ensure electrical energy provide, self-sufficiency and deal with the challenges within the power sector of Botswana. The plant includes of 4 items with capability of 150 megawatt every, totalling 600 megawatt, all coal fired, along with related transmission infrastructure.
Located adjoining to the prevailing 132 megawatt Morupule A plant, Morupule B was constructed at over P10 billion, funded by debt finance from the African Development Bank, and was presupposed to have been accomplished and absolutely commissioned in 2013, nonetheless nearly 10 years later the multibillion-pula plant remains to be not absolutely operational, as a substitute value overruns are reported at over P4 billion nonetheless counting.
In a media briefing early this 12 months Minister of Minerals & Energy Lefoko Moagi stated development of the plant was budgeted for P9 billion, however the complete value of development ended up ballooning to over P12 billion. He defined that out of 4 items solely 2 have been working being Unit 2 and Unit 3, producing 80 megawatt and 150 megawatt respectively.
He stated Unit 1 was at the moment at compelled outage due to complete failure whereas Unit 4 was below commissioning following completion of remedial works. “What we are doing in Morupule B is that we are changing the heat exchangers, and we have requested from the initial designers to furnish us with a new design of heat exchangers, technologically advanced with proper output configurations”.
Minister Moagi defined that the items might be restarted regularly till the plant is absolutely operational at 100% output ranges. Remedial works have been delayed by COVID -19 journey restrictions, and the plant will now be absolutely operational in 2024.
According to Minister Moagi, Botswana won’t incure any value, remedial value might be absolutely taken care of by contractor. “As for us, we had budgeted for P45 million, as incidental costs, because our Engineers will be travelling to Morupule, we will be engaging experts to assess the work for us etc.”
In phrases of efforts towards clear power Minister Moagi stated Morupule A wad already implementing clear coal applied sciences, gasoline gasoline desulphurisation method in place. “At Morupule B the new heat exchangers that we are installing will have reduced gas emissions,” he stated.
