Copperbelt Energy Corporation (CEC) Plc’s electricity supply to Konkola Copper Mines (KCM) has drastically dropped to an average 160 megawatts by the end of 2019, from a peak of around 210 megawatts one year ago, company data reveals.

And CEC plans to invest a 2x20MW solar PV in Kitwe with partner, InnoVent, under GET FiT programme, with an overall intention to invest in up to 200MW in solar technology over the next three to six years.

According to CEC head – power plants and mechanical systems John Silweya, CEC’s power distribution to KCM had sharply dropped to an average 160MW this year, from an average 210MW prior to the provisional liquidation team takeover of the mine in May, this year.

He explained that since mid-2019, KCM’s operational challenges had triggered a sharp drop in its access to electricity at its major mining assets of Nkana, Nchanga and Konkola.

“We supply both the Nchanga Mine and the one in Chililabombwe when they are at their peak with about 210MW. They did have challenges; I think you heard at the smelter, there was a challenge there so now I think the mine in Chililabombwe is doing about 80 MW and in Nchanga, they seem to be recovering, they are doing about 80MW as well now, so maybe about 160MW. But we are hoping that they can recover from those operational challenges, we are here to support them,” Silweya told journalists during a media tour of the Luano substation in Chingola District.

And live data from the control room indicating power distribution across CEC’s vast network across its entire network showed a breakdown in power supply across KCM’s three mining assets.

KCM Nkana accessed around 1.76MW; KCM Nchanga accessed 95.2MW, while KCM Konkola received 78.7MW by the end of November.

And speaking to journalists when he gave an overview of CEC’s operations, managing director Owen Silavwe explained that KCM remained the “wettest mine” in the world, hence the need to continuously supply the underground mining operation with electricity or risk losing the entire asset.

“So, one of the key features of the Copperbelt mines, unlike the or the North-Western Province mines, the Copperbelt mines are underground mines, they operate below the water table so one of the key features is that they tend to be very wet mines. For example, Konkola is the wettest mine in the world and because of that, you need these strategic assets to make sure that of the grid is not there, you have to be able to do critical operations. You need to be able to pump out the water because one of the facts known about Konkola was that if it stayed 30 minutes without pumping water, you basically lose the mine. You may not be able to operate. So, you need to continuously pump out the water, so you can’t afford not to have the ability to pump out if you have no grid at Konkola,” explained Silavwe, who also announced that the mining company had not paid for its electricity off-take for the majority of this year.

CEC is one of the oldest power utilities in the country, established in 1951 by mining companies on the Copperbelt, to manage their electricity supply needs as opposed to each mine managing its own electricity generation and distribution, which was the case prior to that year.

The company now supplies power to 10 mines on the Copperbelt, chief among them being KCM, which despite its ongoing operational challenges, consumes the largest chunk of electricity.

And CEC plans to invest a 2x20MW solar PV in Kitwe with partner, InnoVent, under the government’s GET FiT programme, with an overall intention to invest in up to 200MW in solar technology over the next three to six years.

Company data availed in a powerpoint presentation showed the utility’s ambitious power diversification programme over the next half-decade.

“Developing 2x20MW solar PV in Kitwe with partner, InnoVent, under GET FiT programme; intention to invest in up to 200MW in solar technology over the next three to six years; involved in up to 150MW Upepo hybrid (solar, wind, storage) generation project; participating in GET FiT small hydro programme,” read part of the presentation.

A check at one of the company’s 1MW solar pilot project showed that efforts were already underway to actualize this agenda.

“We installed this plant in April, 2018, and the installation took about three weeks. It’s a one megawatt (plant) and the output in simple terms, can power up to 500 big houses. If it’s these small houses in the compound, it can be in excess of 1,000 (houses). The number of panels installed is about 3,800; we have 24 inverters and we have got an 11 KV evacuation line. This power we are using here is consumed at CEC only. This is a pilot plant; we were thinking that before we embark on a bigger project, it’s better we learn, we start small then it had been strategically located near CBU (Copperbelt University) because we also want to assist CBU; we have got about 42 hectares of land, which is earmarked for the same facility. This is one megawatt and we hope the rest of the land, which is remaining, we should be able to put about 20 megawatts,” CEC project manager in charge of business development Cassious Chongo said during a tour of the 1MW plant in Kitwe last week.

“Solar energy is reliable enough, but it has got its negative sides because its intermittent. By that I mean that when there is some disturbance, the output drops. So, on this one, the next project we are working on is the battery storage where we should be able to mitigate that by installing the battery storage.”

CEC mostly owns transmission and distribution infrastructure, whose key usage is when the national grid is unavailable.

A big chunk of it is at Luano substation, which has generating capacity of 40MW; 20MW in Chililabombwe; 10MW in Mufulira and another 10MW in Luanshya.

Copperbelt Energy Corporation (CEC) Plc chief executive officer Owen Silavwe says talks are underway with Zesco Limited to renew the Bulk Supply Agreement (BSA) ahead of the expiry of the existing one, which lapses next year.

And Silavwe says the decision to not load shed mining companies in Zambia is more “economical” and not an act of selfishness as the country’s economy is largely influenced by the performance of the sector.

Speaking during a media interaction with journalists at the company’s head office in Kitwe, Wednesday, Silavwe announced that the power utility was in talks to renew their BSA with Zesco as not renewing the agreement would spell doom for its Copperbelt commercial and retail clients, who are being supplied electricity from CEC.

CEC currently supplies a stable supply of electricity to 10 major corporate clients in the province, including Konkola Copper Mines (KCM) Plc, its biggest client who consume largest chunk of power from its network.

The power utility also supplies to its retail clients, non-mining consumers, across the province at an average tariff of 3.5 US cents per kilowatt hour.

“We supply the power to everybody on the Copperbelt so it’s a question of how are we going to ensure that we do this in a way that will not antagonize the sector or the economy, I think that for me is quite critical. And I don’t think we have any challenges in achieving that in a very amicable and efficient way. I think what I would say is there is work that’s going on at the moment and that work is meant to find a solution to this. The Bulk Supply Agreement underpins the supply of power to everybody in the Copperbelt; it’s not just the mines, basically everybody on the Copperbelt. So, my view on it is that whichever way you look at it, a solution has to be found, if renewal is the solution, then so be it. But the critical takeaway is that a solution needs to be found, otherwise come that, day, nobody would want to see challenges on the Copperbelt, and basically challenges to the economy,” Silavwe said.

“So, we should try, as a country, to avoid dooms day! I don’t think we plan for dooms day. We are working on it, but we don’t have a conclusion today. The fact is process is ongoing, today. It’s not about what I want to see, it what is mutually agreed between the parties at the end of the day, that is important.”

And Silavwe explained CEC worked hard to ensure that the country’s power deficit did not affect mining companies.

“CEC supplies power to the mines on the Copperbelt; Zesco supplies power directly to the mines in North-Western so all the mines, whether on the Copperbelt or North-Western, they are currently not being load shed. It’s not just the mines on the Copperbelt. And the reason for that is obviously to try and protect the economy. At the moment, as I understand it, and it’s not that CEC is being selfish that’s why they are not being load shed. So, we obviously try and coordinate actions whether we are working through ourselves or we are working through the Ministry (of Energy), we try and make sure that we coordinate our efforts,” said Silavwe.

“One of the things we do as CEC is, if, for example, the mines need to be load shed, we try and make sure we use our contracts within the region to buy power and supplement whatever gaps are there because, remember the challenge with the mines is that if, for example, you take away 10 per cent of their power because they are running processes that are basically interconnected, they are dependent on each other. You might find that the mine actually needs to close, if they can’t run one process, it basically means they can’t run a subsequent process and they can’t run the next process. So, generally, what you try and do is to protect that to ensure that you protect the mine operations and you ensure that you don’t end up in that scenario. Most of the local residents on the Copperbelt work on the mines because the mines are second largest employer after government.”

US $200m two solar power projects are set to build in Zambia. Funded by the Japanese Renewable Energy Company Univergy Solar, the two plants are expected to add a total of 200MW to the country’s national grid next year.

According to a statement from Zambia’s embassy in Tokyo, Univergy Solar Company is expected to develop and implement a 135MW project in northern Zambia and another 65MW project in Zambia’s copperbelt.

Furthermore, the solar power project will be implemented in collaboration with a Zambian company and is expected to create hundreds of jobs and business opportunities for local firms engaged to maintain the solar farms and generation plants.

Construction timeline

The Japanese firm will sign a Memorandum of Understanding (MOU) with the Zambian government to start work on the projects in the first quarter of 2020. The two projects are expected to be completed between six and eight months after the commencement date.

Zambia mainly relies on hydropower and has an electricity deficit of about 750MW due to low water levels at generation plants after a severe drought hit power production. The country cut its economic growth forecast to around 2% for 2019, from an estimated 4%, due to the impact of the drought on its power supply and agricultural production.

Solar power in Zambia

Zambia expects to triple power output to 6,000 megawatts (MW) in 2 years through expansion of solar energy by foreign investors, the head of its investment agency said.

Erratic electricity supplies have hit mining in the continent’s second-biggest copper producer, where the bulk of its generation capacity of 2,200MW of power is water-powered. The power problems and copper price slide have driven the kwacha currency to record lows amid a selloff in commodity-linked currencies as top copper consumer China’s economy has slowed.
