Karuma hydroelectric power station is expected to be operational in March 2023 according to the Minister for Energy and Mineral Development, Ruth Nankabirwa. Nankabirwa made the revelation while announcing the 2023 electricity end-user tariffs in Kampala, the capital of Uganda.
The dam’s commissioning has been extended more than thrice. The first completion date was set for December 31, 2019. However, this date was extended to November 30, 2020, and later to June 22, 2022.
The Uganda Electricity Generation Company (UEGCL) has blamed the persistent delays on procurement hurdles, in addition to delays by the government to hand over land for the project, and hostile weather, including torrential rain, which slowed down some of the construction works.
Recently, UEGCL attributed the delays to discrepancies in electromechanical installations such as electric cables, wiring systems in the tunnels, and the fire extinguishing system which they say are being fixed.
Karuma Hydroelectric Power Station Project Overview
Karuma hydroelectric power station project is on the Nile River, in Kyandongo District, Uganda. Uganda’s Ministry of Energy and Mineral Development (MEMD) and Uganda Electricity Generation Company Limited (UEGCL) are spearheading the 600MW run-of-the-river power facility project.
The project comprises the construction of a 20m-high and 312m-long roller compact concrete (RCC) gravity dam. Upon completion, it will be the largest of its kind in East Africa. It will have a 35 km-long reservoir spread across an area of 2,737ha. At an estimate, the gross reservoir volume is 79.87 million m³.
The Karuma hydroelectric power station project will also involve the construction of six 20m-high and 29m-wide water intake towers. Six 7.7m diameter and up to 379m-long concrete lined pressure shafts. In addition, a 200m-long, 21.3m-wide, and 53m-high underground powerhouse cavern housing six 100MW vertical Francis turbines will be built. The turbines will operate under a gross head of 70m and a speed of 150 rotations per minute (rpm).

Moreover, two 314m-long, 21.5m-wide, and 50m-high orifice-type tailrace surge chambers will also be a part of the project. This is where water will go back to the river through two 12.9m diameter horseshoe-shaped tailrace tunnels approximately 8.6km long. The design discharge for the hydropower plant will be 1,128m³/s.
Power from the Karuma hydroelectric power station will derive from an underground transformer cavern located just above the underground powerhouse. The 200m-long, 18.0m-wide, and 14.4m-high transformer cavern will be with six 11kV/400kV step-up transformers. It will be connected with the powerhouse through a 40m-long bus duct tunnel.
Three transmission lines will be in use to feed the electricity generated by the facility to the national grid. These lines include the 248km-long 400kV Karuma-Kawanda line, the 55km-long Karuma-Olwiyo line, and the 80km-long Karuma-Lira transmission line. Furthermore, the project involves the construction of three new substations at Karuma, Kawanda, and Olwiyo. These will be built by the Uganda Electricity Transmission Company (UETCL).
Karuma hydroelectric power station project will cost at least US$ 1.7bn. It is financed 85% through a soft loan from the Export-Import (Exim) Bank of China, while the Ugandan government provides the remaining 15%. The loan’s repayment will be over a period of 25 years, at an average interest rate of 3%.
The Ugandan government first had plans for the construction of a power station at Karuma Falls in 1995. Norpak, a Norwegian energy company was contracted to conduct the feasibility study and the environmental impact assessment (EIA) for the dam. The project was to receive financing from the World Bank through a loan.
In October 2006, the project’s feasibility study was released. In November of the same year, the government invited bids for the construction of the project. The initial plan was to build a 200-250 MW power station.
In 2009, the project plans to develop a much bigger dam of 750 MW. In the same year, Norpak withdrew from the project citing financial challenges due to the Global Recession of 2008-2012. Energy Infratech Private Limited was contracted to conduct a fresh feasibility study as well as EIA.
In July 2011, the project’s capacity was brought down to 600 MW. Some international development partners wanted to scale back even further, to a maximum capacity of 400 to 450 megawatts.
Construction work at the power station officially began on 12 August 2013.

No financial closure yet for Uganda’s Karuma hydropower project
The total cost of the project is US$1.7bn. This amount includes the costs, of building transmission lines to where the power will go into the national grid. The project will generate 600MW of electricity once complete.
85% of the project’s funding is to be through a soft loan from Exim Bank by the Chinese firm. Meanwhile, Uganda was to cater for the remaining 15%. The firm has now asked the Ugandan government to pay its 15% share of the deal upfront. In order to speed up the project which is several years behind schedule.
Getting back on track
According to Energy Minister Irene Muloni, the Ugandan Government will collaborate with the contractors. Work had already begun at the site adding that they were not going to delay the project further.
Sinohydro has confirmed that if China Exim Bank does not hold up to its end of the deal, then it will have to discontinue.
The project has had various challenges arising from allegations of corruption in the process of procuring the tender. Alongside challenges of getting manpower to operate the machines.
In March 2015, Alstom was subcontracted by Sinohydro, the lead contractor on the project to supply equipment and technical services to the power station. Alstom got $65 million in the deal.

Karuma hydropower plant in Uganda to start construction of transmission lines
Uganda’s 600MW Karuma hydropower plant will commence the construction of transmission power lines; this is after intec – GOPA-International Energy, a German energy consulting company agreed on a US$ 6.3m consultancy services contract.
Funding for the construction of the transmission lines at the Karuma hydropower plant is from China’s Exim bank.
Eriasi Kiyemba, Uganda Electricity Transmission Company Limited (UETCL) Managing Director spoke about the project. He said the transmission lines at the Karuma hydropower plant were to increase and improve power service delivery.
“The government through UETCL, the implementing agency, will construct the Karuma- Kawanda 440kV. It will also construct Karuma-Olwiyo 400kV and Karuma -Lira 132kV transmission lines. They’ll provide adequate capacity to evacuate power generation at the Karuma Hydro Power station (HPS),” Mr. Kiyemba said.
Construction should be complete in 2018 and the Karuma Interconnection Project’s commissioning in 2017. Klaus Langschield, a consultant with Gopa-International Energy, said they have the expertise to do the work within the specified time.
The government awarded the Engineering, Procurement, and Consultancy (EPC) contract of the construction to Sinohydro Corporation.

Construction of Karuma dam in Uganda hit by cement and labor shortage
Contractors for the Karuma dam in Uganda had complaints over a shortage of the right quality of cement and workers that has adversely slowed their operations.
In a media brief to journalists over the weekend at the construction site, the Karuma Hydropower plant project liaison officer Mr. Qu Jinwei said they were forced to source the High grade 42.5 cement from Kenya since both Hima and Tororo cement factories could not deliver the qualities they need as they are used to producing the ordinary cement.
“We had an inspection at their factories before we started the project and after observing they could not supply the qualities, we had to look elsewhere and we found Savanah Cement in Kenya,” he said.
In response to the causes of the cracks in the dam, he said the cracks do not have a direct correlation to the cement used because they are negligible and they happen all the time in such types of projects. He said they would hold consultations with the parent company in China so as to rectify them. Mr. Jinwei said another major challenge encountered is the lack of qualified dumper truck drivers who can work in the tunnels where a lot of the operations take place.
“We have had many drivers who come on-site but when we take them to the highly restricted area where most of our operations are, many of them cannot maneuver the trucks through the tunnels,” he said.
Mr. Alok Kala, Tororo Cement’s chief marketing manager rubbished remarks over the quality of their cement saying the contractor never bought their cement but they have been supplying it to the Isimba hydro dam.
One of the drivers who spoke on condition of anonymity, rubbished claims that Ugandan drivers cannot operate and manage the trucks, saying that the pay is way below the workload.
This comes barely a few days after senior officials’ suspension from the ministry of energy by President Museveni after it came to light that they did shoddy work at the Karuma and Isimba dams. Among those axed are Engineers Paul Mubiru, Henry Bidasala, and Cecilia Menya

Karuma construction project contract locks out suppliers in Uganda
A Ugandan government official has said workers and suppliers in Uganda have no control in contributing to the ongoing Karuma construction project because the contractor is fully in charge of the contract.
Mr. Henry Bidasala Igaga, the electrical energy commissioner at the Ministry of Energy spoke about the issue. He said Ugandans should expose themselves to market forces. More especially in terms of meeting the qualities, quantities, and price that the contractors are offering because this is a “turn-Key contract”.
“The contractor is responsible for the engineering, procurement, construction materials, and services. What we want is delivery of the final product,” he said on the telephone on Monday.
‘Buy Uganda, Build Uganda’
Mr. Bidasala’s comments come after Ugandan manufacturers lodged several complaints. They were mostly centered around their products being put aside in the ongoing construction project. Earlier in a different encounter, the contractor said that they did not source cement from Tororo and Hima cement plants. Their reason said being because they did not meet the quality and quantities of cement needed for the project.
In her comment on the matter, the executive director of Public Procurement and Disposal of Public Assets Authority, Ms. Cornelia Sabiti, said under the Oil and Gas Act, the ‘Buy Uganda, Build Uganda’ policy requires that all materials for such projects should be from the local market but she is not sure if the same applies in the energy sector where this is a private contractor.
The government 2014 came up with the policy, following an outcry from the members of the Uganda Manufacturers’ Association. The complaints were highlighting their products were being sidelined for such projects.
Likewise, Tororo Cement and Roofings Rolling Mills said that their cement and steel products are major inputs in the construction of the dam have been rejected by the contractor who instead would rather import the products from Kenya and China.
Mr. Alok Kala, the chief marketing officer at Tororo Cement Limited, said that in last year alone, the contractor brought in 32,000 metric tonnes of cement from Kenya’s Savannah Cement which is also said to have Chinese links.
Countries dealing in gas and oil production or mining are coming up with ‘local content requirements.
The development of local content follows many years of oil and gas or mineral exploitation in several developing countries, where the citizens seem to benefit very little.

Compensation to delay Uganda’s Karuma Power Project
Difficulties in acquiring land for the Karuma interconnection project are likely to delay the commissioning of the 600MW hydropower plant. The Uganda Electricity Generation Company Ltd chief executive officer, Mr. Harrison Mutikanga, has revealed.
The power plant, which began in August 2013, is due for commissioning in December 2018. However, according to Mr. Mutikanga, despite the progress of ongoing works at the Karuma Hydropower project, commissioning it on schedule remains uncertain. This is due to land-related issues where transmission lines will cross.
Electricity from the power plant’s evacuation will be through Karuma -Kawanda (305km), Karuma-Olwiyo (60km), and Karuma- Lira (80km). More than 4,000 affected people on the transmission routes will reeve compensation.
Mr. Mutikanga further said that they are working closely with the Ministry of Energy, the Finance Ministry, and Uganda Electricity Transmission Co Ltd (UETCL). “They have to ensure that the problems are rectified and the project remains on schedule,” he added.
Mr. Edward Mutesa, the principal project officer- social Aspect at UETCL, the firm undertaking the interconnection project; said that they are already behind schedule by six months due to emerging land disputes.
He noted that the biggest challenges are on the Karuma-Kawanda, the longest route where there are several overlapping titles by landowners between the Nakasongola and Wakiso districts.
According to Mr. Mutesa, owners of the land on the Karuma-Lira route have a lot of incitement from lawyers to get more money.
He said that out of the 4,135 people affected by the interconnection project, 2,791 have so far had compensation. This is a total of US $ 3m of the US $5.6m meant to compensate all the affected landowners.
Mr. Albert Byaruhanga, the Karuma Hydropower project manager, has also noted some concerns on the dam section and its power intake.
“According to its design, this project is to serve more than 50 years. However, we worry that it can create a lot more problems in the future during the operation of the plant. This will happen if there is no quality control,” Mr. Byaruhanga said.
As of February 2018, 74% of the project had been completed. In June of the same year, 76% of the work had been complete.
As of April 2019, around 80% of the project was complete. Three high-voltage transmission lines were 80 to 85% complete at the time.
Uganda’s Karuma power project is soon to be commissioned
