Mekin Hydroelectric Power Station

Mekin Hydroelectric Power Station 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 Mekin Hydroelectric Power Station rather than just read about it. In short: The Mekin Hydroelectric Power Station, also referred to as Mekin Power Station, is a 15 MW (20,000 hp) hydroelectric power station, in Cameroon. This power station has been under construction since early 2010s, with initial commissioning planned for 2015.

Key takeaways

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

Reference excerpt

The Mekin Hydroelectric Power Station, also referred to as Mekin Power Station, is a 15 MW (20,000 hp) hydroelectric power station, in Cameroon. This power station has been under construction since early 2010s, with initial commissioning planned for 2015. However, the project has been beset by multiple delays, plant shutdowns and restarts. The power station was partially re-started in June 2022 to allow the generation and evacuation of 11.25 MW of electricity, comprising 75 percent of maximum capacity. When current production testing is concluded, it is expected that the final unit will be brought online during the fourth quarter of 2022. This renewable energy infrastructure project is under development by Mekin Hydroelectric Development Corporation (Hydro Mekin also HydroMekin), a Cameroonian independent power producer (IPP). The energy off-taker is ENEO Cameroon S.A., the public-private partnership electricity utility company. The electricity is intended for distribution primarily, in the Dja and Lobo Department of the South Region of Cameroon, where the power station is located.

Location The power station straddles the Dja River, immediately downstream of its confluence with the Lobo River, in Mekin Village, in the Dja and Lobo Department of the South Region of Cameroon. Mekin is located approximately 75 kilometres (47 mi), northeast of the town of Sangmélima, the departmental headquarters. This is approximately 194 kilometres (121 mi) southeast of Yaoundé, the capital city of Cameroon. The geographical coordinates of Mekin Hydroelectric Power Station are:3°15'34.0"N, 12°25'17.0"E (Latitude:3.259444; Longitude:12.421389).

Overview The design calls for a rock-fill dam with four generation turbines, each rated at 3.75 MW for total generation capacity of 15 MW. The energy leaves the generation turbines at 63kV. At the substation outside the power station, the energy is stepped up to 110kV. It is then transmitted via overhead high voltage transmission cables to an ENEO substation at Ndjom Yekomo. There the energy is stepped down to 30kV and then entered into the ENEO grid for distribution.

Construction and funding The engineering, procurement and construction (EPC) contractor is China National Electric Engineering Company (CNEEC). The initial budget was CFA 25 billion(approx. €40 million), with Exim Bank of China lending 85 percent and the government of Cameroon contributing 15 percent. As of June 2022, with multiple cost overruns, at least €52.5 million has been spent on construction.

Worked examples

Example 1 — a first encounter with Mekin Hydroelectric Power Station

Start with the simplest possible case. Write down what Mekin Hydroelectric Power Station 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 Mekin Hydroelectric Power Station 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 Mekin Hydroelectric Power Station 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 Mekin Hydroelectric Power Station

In research: Mekin Hydroelectric Power Station 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 Mekin Hydroelectric Power Station 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: Mekin Hydroelectric Power Station is common in secondary-school and first-year university syllabi. It links to neighbouring topics Energy infrastructure under construction, Hydroelectric power stations in Cameroon, South Region (Cameroon), so understanding it makes those chapters shorter.
In everyday life: Look for Mekin Hydroelectric Power Station 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.
