Karuma–Juba High Voltage Power Line

Karuma–Juba High Voltage Power Line is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Karuma–Juba High Voltage Power Line rather than just read about it. In short: The Karuma–Juba High Voltage Power Line is a planned high voltage electricity power line, connecting the high voltage substation at Karuma, in Kiryandongo District, in the Western Region of Uganda, to another high voltage substation at Juba, in Jubek State, in South Sudan. Location The 400kV power line, begins at the 400kV substation at Karuma Hydroelectric Power Station.

Key takeaways

  • Karuma–Juba High Voltage Power Line belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Karuma–Juba High Voltage Power Line to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Karuma–Juba High Voltage Power Line from memory before moving on to harder problems.

Reference excerpt

The Karuma–Juba High Voltage Power Line is a planned high voltage electricity power line, connecting the high voltage substation at Karuma, in Kiryandongo District, in the Western Region of Uganda, to another high voltage substation at Juba, in Jubek State, in South Sudan.

Location The 400kV power line, begins at the 400kV substation at Karuma Hydroelectric Power Station. The line travels in a north-westerly direction to Olwiyo, in Nwoya District, in the Northern Region of Uganda. This distance is approximately 56 kilometres (35 mi). At Olwiyo, the line takes a general northerly direction to Elegu at the international border with South Sudan, a distance of about 140 kilometres (87 mi). The distance traveled by this power line in Uganda is therefore approximately 196 kilometres (122 mi). After crossing the international border into South Sudan, the line travels through Nimule, in Imatong State to Juba, the capital city of South Sudan, a distance of approximately 195 kilometres (121 mi)

Overview This power line is planned to transmit electricity from the 600 megawatts Karuma Hydroelectric Power Station in Uganda, to Juba in South Sudan. It is part of the regional power-sharing protocols of the Nile Equatorial Lakes Subsidiary Action Program and of the East African Community. Uganda plans to sell electricity to neighboring countries, including South Sudan after Karuma Hydroelectric Power Station and Isimba Hydroelectric Power Station become operational. The government of South Sudan has plans to extend the high-voltage power line to Juba.

Construction The two governments are in discussions on how to fund the construction of the power line, using loans from the Japan International Cooperation Agency, with each country being responsible for the portion of the line in her territory. The feasibility and environmental impact studies for the 400kV power line were carried out between March 2023 and February 2024 by CESI S.p.A. and ELC Electroconsult S.p.A. both of Italy and Colenco Consulting Limited of Nigeria.

Developments In June 2023, South Sudan government officials signed a power purchase agreement (PPA) with officials from the Ugandan Ministry of Energy and Mineral Development. Under the agreement, Uganda will increase the voltage of the section of this transmission line that is in Uganda, from 132kV to 400kV. In addition, Uganda will supply power to several towns in South Sudan bordering Uganda, including Nimule, Elegu, Oraba, Kaya and others. South Sudan will be responsible for extending the transmission line to Juba.

In May 2024, high ranking executives from Sinohydro met with the president of Uganda and offered to construct the 140 kilometres (87 mi) Olwiyo-Nimule section of this power line for approximately US$180 million. Sinohydro also offered to finance the project if necessary. The construction funding of this power line is summarized in the table below. The total cost is estimated at US$302 million (€277.6 million), sourced as outlined here.

Worked examples

Example 1 — a first encounter with Karuma–Juba High Voltage Power Line

Start with the simplest possible case. Write down what Karuma–Juba High Voltage Power Line claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Karuma–Juba High Voltage Power Line before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Karuma–Juba High Voltage Power Line ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Karuma–Juba High Voltage Power Line

In research
Karuma–Juba High Voltage Power Line appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Karuma–Juba High Voltage Power Line in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Karuma–Juba High Voltage Power Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in South Sudan, Energy in Uganda, Energy infrastructure in Africa, so understanding it makes those chapters shorter.
In everyday life
Look for Karuma–Juba High Voltage Power Line outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
