Reference excerpt

The Lira–Gulu–Nebbi–Arua High Voltage Power Line is an operational high voltage electricity power line in Uganda. It connects the high voltage substation at Lira, in Lira District, to another high voltage substation at Arua, in Arua District, all in the Northern Region of the country.

Location The 132 kilo Volt power line starts at the 132kV substation at Lira, approximately 337 kilometres (209 mi), by road, north of Kampala, Uganda's capital and largest city. The power line travels in a general northwesterly direction to Gulu, the largest city in Northern Uganda, a distance of approximately 110 kilometres (68 mi), by road from Lira. From Gulu, the power line continues in a general southwesterly direction to Nebbi, in Nebbi District, approximately 173 kilometres (107 mi) away, by road. From Nebbi, the power line turns northwest and runs another 80 kilometres (50 mi), to end in the city of Arua. The power line which does not track the roads all the time has a total length of about 294 kilometres (183 mi).

Overview This power line is intended to transmit electricity in an improved, sustainable manner to Uganda's Northern Region and extend the national electric grid to the West Nile sub-region. This is in line with government of Uganda's Vision 2040 to achieve middle income status by 2040.

Associated substations The work includes the construction of 132kV substations at Gulu, Nebbi and Arua, and the expansion of the existing 132kV substation at Lira. If the Lira substation cannot be expanded for technical reasons, a brand new second 132kV substation will be built at Lira.

Construction The government of Uganda obtained financing in the amount of US$100 million, from the International Development Association to fund the construction of this energy project. The government contributed US$27.3 million to project costs. As of 5 May 2016, the feasibility studies, population resettlement plans and the acquisition of a procurement consultant had been completed. Work on soliciting of a contractor began in September 2016, with completion expected in 2022. In July 2020, the construction contract was awarded to KEC International Limited of India and a joint venture company comprising AVIC International Holding Corporation and Central Southern China Electric Power Design Institute Company Limited. Construction was expected to last two years and conclude in the second half of 2022.

Developments In August 2024, Uganda Electricity Transmission Company Limited energized the Nebbi substation on this line, thereby connecting the West Nile sub-region to Uganda's national grid.

Worked examples

Example 1 — a first encounter with Lira–Gulu–Nebbi–Arua High Voltage Power Line

Start with the simplest possible case. Write down what Lira–Gulu–Nebbi–Arua 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 Lira–Gulu–Nebbi–Arua 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 Lira–Gulu–Nebbi–Arua 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 Lira–Gulu–Nebbi–Arua High Voltage Power Line

In research: Lira–Gulu–Nebbi–Arua 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 Lira–Gulu–Nebbi–Arua 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: Lira–Gulu–Nebbi–Arua High Voltage Power Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in Uganda, Energy infrastructure in Africa, High-voltage transmission lines in Uganda, so understanding it makes those chapters shorter.
In everyday life: Look for Lira–Gulu–Nebbi–Arua 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.
