Electricity generation: One step forward, two steps backward

Nearly 10 years and over P10 billion later, Morupule B Ė a 600 Megawatt coal fired power plant that was envisaged to end Botswana Ďs national power crises still canít deliver to full capacity, forcing the country† to pay over P2 billion annually in importation of power from surrounding producer nations.†

The latest quarterly report from Statistics Botswana, reviewing the countryís power generation for the fourth quarter of 2021 has written off the progress made during the third quarter, reporting a quarter-on-quarter decrease of 18.9 percent, from an Index of Electricity Generation (IEG) of 137.7 during the third quarter of 2021 to 111.7, giving a clear reflection that the country takes 2 steps forward and 3 steps backward as far as local power generation is concerned.

In the third quarter of 2021, electricity generation had picked up, with a 14.6 percent points jump on IEG, from the Index of 120.2 during the second quarter of 2021. In physical terms, local electricity generation had increased by 14.6 percent (73,723 MWH), from 505,313 MWH during the second quarter of 2021.Statistics Botswana had credited the increase to improved performance of Morupule A and B power stations.

However in a setback during the last quarter of 2021 production of electricity locally took a downturn, both on quarterly and year-on-year basis, mainly due operational challenges at Morupule B. A year-on-year analysis shows a decrease of 9.3 percent in IEG, compared to 123.1 recorded during the corresponding quarter in 2020.

The physical volume of electricity generated decreased by 9.3 percent (48,278 MWH), from 517,627 MWH during the fourth quarter of 2020 to 469,349 MWH during the current quarter.

The quarter-on-quarter perspective shows that local electricity generation decreased by 18.9 percent (109,686 MWH), from 579,036 MWH during the third quarter of 2021 to 469,349 MWH during the period under review. ďThis decrease was largely due to operational challenges at Morupule B power plant.Ē Said Statistics Botswana

A decrease in local generation means increase in importation, during the fourth quarter of 2021, the physical volume of imported electricity increased by 16.7 percent (77,716 MWH), from 465,701 MWH during the fourth quarter of 2020 to 543,417 MWH during the quarter under review.

Compared to the previous quarter, electricity imported during the fourth quarter of 2021 increased by 28.0 percent (118,714 MWH), from 424,703 MWH during the third quarter of 2021 to 543,417 MWH.

Botswana imported 53.7 percent of total electricity distributed during the fourth quarter of 2021. Eskom, South Africaís state-owned power generation outfit was as usual the main source of imported electricity at 40.6 percent of total electricity imports.

The Zambia Electricity Supply Corporation Limited (ZESCO) accounted for 22.0 percent, while the remaining 17.0, 15.0, 4.0 and 1.4 percent were sourced from Electricidade De Mozambique (EDM), Southern African Power Pool (SAPP), Cross-border electricity markets and Nampower, respectively.

Cross-border electricity markets is a Statistics Botswana nomenclature referring to†towns and villages along the border which are supplied with electricity directly from neighbouring countries such as Namibia and Zambia.

In terms of distribution year-on-year analysis shows that the amount of distributed electricity increased by 3.0 percent (29,438 MHW), from 983,328 MWH during the fourth quarter of 2020 to 1,012,766 MWH during the current quarter.

The quarter-on-quarter comparison of distributed electricity shows an increase of 0.9 percent (9,028 MWH), from 1,003,738 MWH during the third quarter of 2021 to 1,012,766 MWH during the review quarter.

Electricity generated locally contributed 46.3 percent to electricity distributed during the fourth quarter of 2021, compared to a contribution of 52.6 percent during the same quarter in 2020, a decrease of 6.3 percentage points.

The quarter-on-quarter comparison shows that the contribution of electricity generated to electricity distributed decreased by 11.4 percentage points compared to the 57.7 percent.

MORUPULE B CHALLENGES†

The Morupule B project was adopted as the least cost solution to guarantee electricity supply, self-sufficiency and address the challenges in the energy sector of Botswana. The plant comprises of 4 units with capacity of 150 megawatt each, totalling 600 megawatt, all coal fired, together with associated transmission infrastructure.

Located adjacent to the existing 132 megawatt Morupule A plant, Morupule B was constructed at over P10 billion, funded by†debt finance from the African Development Bank, and was supposed to have been completed and fully commissioned in 2013, however almost 10 years later the multibillion-pula plant is still not fully operational, instead cost overruns are reported at over P4 billion still counting.

In a media briefing early this year Minister of Minerals & Energy Lefoko Moagi said construction of the plant was budgeted for P9 billion, but the total cost of construction ended up ballooning to over P12 billion. He explained that out of 4 units only 2 were working being Unit 2 and Unit 3, producing 80 megawatt and 150 megawatt respectively.

He said Unit 1 was currently at forced†outage because of total failure while Unit 4 was under 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 explained that the units will be restarted gradually until the plant is fully operational at 100 percent output levels.†Remedial works were delayed by COVID -19 travel restrictions, and the plant will now be fully operational in 2024.

According to Minister Moagi, Botswana will not incure any cost, remedial cost will be fully 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 terms of efforts toward clean energy Minister Moagi said†Morupule A wad already implementing clean coal technologies, fuel gas desulphurisation technique in place. ďAt Morupule B†the new heat exchangers that we are installing will have reduced gas emissions,” he said.

New Khoemacau owners commit to mine’s multibillion Pula expansion

6th December 2023

The future of Botswana’s largest copper and silver operation, Khoemacau Copper Mining, looks promising as the new owners, MMG Group, commit to the mine’s expansion plans. MMG, an Australian headquartered company owned by China, has expressed its dedication to doubling Khoemacau’s production and transforming it into one of the most significant high-grade copper operations in Africa.

Nan Wang, the Executive General Manager for Australia and Africa at MMG, stated that while the immediate focus is on maintaining a consistent production level of 60ktpa, there are solid plans to increase Khoemacau’s production capacity. The company aims to double its production from 3.65Mtpa to 8.15Mtpa, resulting in an increase in payable copper from approximately 60ktpa to around 130ktpa.

To achieve this expansion, Khoemacau has completed a pre-feasibility study on the project and a solar power initiative. The next step is to conduct a feasibility study, which will pave the way for increased production capacity. Additionally, Khoemacau has identified extensive exploration opportunities across its license area, positioning the company for an exciting new phase of development.

The current Khoemacau operation reached full production and nameplate capacity in December 2022, following over a decade of investment totaling over P10 billion. This significant investment allowed for an intense exploration program, resulting in the development of the most automated underground mining operation in Botswana. The first concentrate was produced in June 2021, and the product entered the export market in July of the same year. Throughout 2022, the company has been working on the pre-feasibility study for the expansion project, with the feasibility study scheduled for the following year.

The expansion plans will involve the construction of a new world-class process plant in Zone 5, where the current mining of ore takes place. This new plant will be larger than the existing one in Boseto, which currently receives ore from Zone 5. The expansion will also involve the development of new underground mines, including Mango, Zone 5 North, and Zeta North East. These additional mines will bring the total number of underground shafts at Khoemacau to six. The ramp-up of production from the expansion is expected to occur in 2026.

Khoemacau, which acquired assets in the Kalahari Copper Belt after the liquidation of Discovery Metals in 2015, currently employs over 1500 people, with the majority being Batswana. The Khoemacau Mine is located in north-west Botswana, in the emerging Kalahari Copperbelt. It boasts the 10th largest African Copper Mineral Resource by total contained copper metal and is one of the largest copper sedimentary systems in the world outside of the Central African Copperbelt.

The mine utilizes underground long hole stoping as its mining method and conventional sulphide flotation for processing. Resource drilling results have shown the existing resources to have continuity at depth, and there are several exploration targets within the tenement package that have the potential to extend the mine’s life or increase productivity.

The Zone 5 mine has already ramped up production, and further expansion in the next five years will be supported by the deposits in the Zone 5 Group. The estimated mine life is a minimum of 20 years, with the potential to extend beyond 30 years by tapping into other deposits within the tenement package.

In conclusion, the commitment of MMG Group to Khoemacau’s expansion plans signifies a bright future for Botswana’s largest copper and silver operation. With the completion of pre-feasibility and feasibility studies, as well as significant investments, Khoemacau is poised to become one of Africa’s most important high-grade copper operations. The expansion project will not only increase production capacity but also create new job opportunities and contribute to the economic growth of Botswana.

BPC Signs PPA with Sekaname Energy

6th December 2023

The Botswana Power Corporation (BPC) has taken a significant step towards diversifying its energy mix by signing a power purchase agreement with Sekaname Energy for the production of power from coal bed methane in Mmashoro village. This agreement marks a major milestone for the energy sector in Botswana as the country transitions from a coal-fired power generation system to a new energy mix comprising coal, gas, solar, and wind.

The CEO of BPC, David Kgoboko, explained that the Power Purchase Agreement is for a 6MW coal bed methane proof of concept project to be developed around Mmashoro village. This project aligns with BPC’s strategic initiatives to increase the proportion of low-carbon power generation sources and renewable energy in the energy mix. The use of coal bed methane for power generation is an exciting development as it provides a hybrid solution with non-dispatchable sources of generation like solar PV. Without flexible base-load generation, the deployment of non-dispatchable solar PV generation would be limited.

Kgoboko emphasized that BPC is committed to enabling the development of a gas supply industry in Botswana. Sekaname Energy, along with other players in the coal bed methane exploration business, is a key and strategic partner for BPC. The successful development of a gas supply industry will enable the realization of a secure and sustainable energy mix for the country.

The Minister of Minerals & Energy, Lefoko Moagi, expressed his support for the initiative by the private sector to develop a gas industry in Botswana. The country has abundant coal reserves, and the government fully supports the commercial extraction of coal bed methane gas for power generation. The government guarantees that BPC will purchase the generated electricity at reasonable tariffs, providing cash flow to the developers and enabling them to raise equity and debt funding for gas extraction development.

Moagi highlighted the benefits of developing a gas supply industry, including diversified primary energy sources, economic diversification, import substitution, and employment creation. He commended Sekaname Energy for undertaking a pilot project to prove the commercial viability of extracting coal bed methane for power generation. If successful, this initiative would unlock the potential of a gas production industry in Botswana.

Sekaname Energy CEO, Peter Mmusi, emphasized the multiple uses of natural gas and its potential to uplift Botswana’s economy. In addition to power generation, natural gas can be used for gas-to-liquids, compressed natural gas, and fertilizer production. Mmusi revealed that Sekaname has already invested $57 million in exploration and infrastructure throughout its resource area. The company plans to spend another $10-15 million for the initial 6MW project and aims to invest over $500 million in the future for a 90MW power plant. Sekaname’s goal is to assist BPC in becoming a net exporter of power within the region and to contribute to Botswana’s transition to cleaner energy production.

In conclusion, the power purchase agreement between BPC and Sekaname Energy for the production of power from coal bed methane in Mmashoro village is a significant step towards diversifying Botswana’s energy mix. This project aligns with BPC’s strategic initiatives to increase the proportion of low-carbon power generation sources and renewable energy. The government’s support for the development of a gas supply industry and the commercial extraction of coal bed methane will bring numerous benefits to the country, including economic diversification, import substitution, and employment creation. With the potential to become a net exporter of power and a cleaner energy producer, Botswana is poised to make significant strides in its energy sector.
