Reference excerpt

Pohjolan Voima Oyj (PVO; Swedish: Nordkraft Abp; English: Northern Power Company Plc) is the second biggest Finnish energy company, which owns hydropower and thermal power plants (including biofuel-fired power plants).

History Following World War II, Finland underwent a gradual transition from an agricultural economy towards an increasingly industrial and technological economy. The expansion of the forest industry contributed to rising energy demand and increased the industry's involvement in electricity generation. In 1943, forest industry companies established Pohjolan Voima (PVO) to develop and operate electricity generation capacity. The company initially invested in hydropower and later expanded into thermal and nuclear power generation, including investments in condensing power and nuclear power plants during the 1970s.

Shareholders Pohjolan Voima is a founder and main shareholder of the Olkiluoto Nuclear Power Plant operator Teollisuuden Voima Oyj. Major shareholders of Pohjolan Voima are Finnish pulp and paper manufacturers UPM-Kymmene Oyj and Stora Enso Oyj; other shareholders include power and utility companies owned by several municipalities. Shareholders can receive electricity from each power plant in proportion to their ownership of the shares issued for the same plant or group of plants (so called Mankala principle) by paying the variable costs in proportion to the electricity actually delivered, while the fixed costs are distributed in proportion to the ownership.

Carbon intensity

Transmission grid PVO sold its share of the Fingrid national electricity transmission grid operator with €247.4 million in April 2011. Income was delivered total to the owners in 2012. Biggest shares were UPM/Myllykoski €109 million and Stora Enso ca €37 million.

Worked examples

Example 1 — a first encounter with Pohjolan Voima

Start with the simplest possible case. Write down what Pohjolan Voima 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 Pohjolan Voima 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 Pohjolan Voima 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 Pohjolan Voima

In research: Pohjolan Voima 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 Pohjolan Voima 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: Pohjolan Voima is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Helsinki, Electric power companies of Finland, Energy companies established in 1943, so understanding it makes those chapters shorter.
In everyday life: Look for Pohjolan Voima 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.
