Reference excerpt

Location The power line starts at Olkaria, in Nakuru County, about 111 kilometres (69 mi), by road, north-west of Nairobi, and runs in a north-westerly direction to the Ketraco electricity substation in Lessos, in Nandi County. From there, the power line travels further north-west to Eldoret, in Uasin Gishu County. There, the power line turns southwesterly in direction, to terminate in the city of Kisumu, on the eastern shores of Lake Victoria. The power line measures approximately 290 kilometres (180 mi), in length.

Overview This power line is intended to transmit power from the Olkaria geothermal electricity complex to the Western Kenya counties in the former Nyanza Province, bordering Lake Victoria. Prior to this line being constructed, the region depended on high cost thermal power derived from fossil fuels (at US$0.34 per kWh) or expensive energy imported from neighboring Uganda at US$0.22 per kWh. The transmission line is intended to supply energy to the region is sufficient quantities and at reasonable rates.

Construction This power line project is split into three lots. The first lot, consisting a 400kV line, measuring 213 kilometres (132 mi), stretches from Olkaria to Lessos with maximum carrying capacity of 1,200 megawatts. The second lot, from Lessos to Kisumu, measures 77 kilometres (48 mi) and is a 220kV line, capable of transmitting 400 megawatts of power. The third lot consists of three new substations at Olkaria, Lessos and Kisumu, with a new switch yard at Kibos. The contractors on this project include (a) Kalpataru Power Transmission limited of India (b) NARI Group Corporation, of China and (c) Sieyuan Electric Company and China. The cost of this project is valued at US$94.7 million (KSh9.5 billion). Construction is funded with loans from the Japan International Corporation Agency (JICA). Commissioning of the completed transmission line is expected during the second half of 2021.

Worked examples

Example 1 — a first encounter with Olkaria–Lessos–Kisumu High Voltage Power Line

Start with the simplest possible case. Write down what Olkaria–Lessos–Kisumu 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 Olkaria–Lessos–Kisumu 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 Olkaria–Lessos–Kisumu 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 Olkaria–Lessos–Kisumu High Voltage Power Line

In research: Olkaria–Lessos–Kisumu 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 Olkaria–Lessos–Kisumu 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: Olkaria–Lessos–Kisumu High Voltage Power Line is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy in Kenya, Energy infrastructure completed in 2019, Energy infrastructure in Africa, so understanding it makes those chapters shorter.
In everyday life: Look for Olkaria–Lessos–Kisumu 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.
