Non-Fossil Fuel Obligation

Non-Fossil Fuel Obligation 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 Non-Fossil Fuel Obligation rather than just read about it. In short: The Non-Fossil Fuel Obligation (NFFO) refers to a collection of orders requiring the electricity distribution network operators in England and Wales to purchase electricity from the nuclear power and renewable energy sectors. Similar mechanisms operated in Scotland (the Scottish Renewable Orders under the Scottish Renewables Obligation) and Northern Ireland (the Northern Ireland Non-Fossil Fuel Obligation).

Key takeaways

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

Reference excerpt

The Non-Fossil Fuel Obligation (NFFO) refers to a collection of orders requiring the electricity distribution network operators in England and Wales to purchase electricity from the nuclear power and renewable energy sectors. Similar mechanisms operated in Scotland (the Scottish Renewable Orders under the Scottish Renewables Obligation) and Northern Ireland (the Northern Ireland Non-Fossil Fuel Obligation). Five orders were made under the NFFO before the UK government replaced it with the Renewables Obligation. The first order or 'tranche' was on 1 October 1990 with an average price of 7.51 pence per kWh being paid to energy generators, and the fifth and last was in September 1998 at an average of 2.71 pence per kWh. Contracts for Difference have since replaced the NFFO and Renewables Obligation as the main form of revenue support for low carbon electricity in the UK.

Background The Non-Fossil Fuel Obligation was put in place under the powers of the Electricity Act 1989, under which electricity generation in the UK was privatised. The original intention was to provide financial support to the UK nuclear power generators, which continued to be state-owned. The proposals were enlarged in scope before the obligation was brought into operation in 1990 to include the renewable energy sector. Contracts from the last three rounds remain in place with the generators receiving the agreed amount from the NFPA and the NFPA effectively taking ownership of the Renewables Obligation certificate (ROC) to which the generator is entitled.

Funding Funding for the NFFO was originally generated by the Fossil Fuel Levy, a levy placed on all electricity consumption in the UK. This was collected by Ofgem, which paid it to the Non-Fossil Purchasing Agency, a body created in 1990 by the public electricity suppliers to purchase on the supplier's behalf. The purchasing agency is based in Newcastle upon Tyne. Since the introduction in 2001 of the New Electricity Trading Arrangements, electricity suppliers bid for the electricity and ROCs in competitive auctions held by the Non-Fossil Purchasing Agency, with any shortfall in price being funded by the Levy. As a result of these arrangements, the Non-Fossil Fuel Obligation has been generating a trading surplus, expected to have reached £500m by 2008. The government have been criticised for siphoning off funds from this surplus to contribute to the exchequer, instead of using it to support renewable energy in other ways.

Worked examples

Example 1 — a first encounter with Non-Fossil Fuel Obligation

Start with the simplest possible case. Write down what Non-Fossil Fuel Obligation 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 Non-Fossil Fuel Obligation 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 Non-Fossil Fuel Obligation 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 Non-Fossil Fuel Obligation

In research: Non-Fossil Fuel Obligation 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 Non-Fossil Fuel Obligation 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: Non-Fossil Fuel Obligation is common in secondary-school and first-year university syllabi. It links to neighbouring topics Electric power in the United Kingdom, Renewable energy in the United Kingdom, so understanding it makes those chapters shorter.
In everyday life: Look for Non-Fossil Fuel Obligation 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.
