The Scottish Government uses a range of evidence in its assessment of the future energy system. The whole-system modelling produced by Energy Systems Catapult and which underpins the draft Energy Strategy was completed before the publication of the UNECE report, and was therefore not informed by the UNECE findings.

The Scottish Government position on nuclear power is clear – we do not support the construction of new nuclear power stations in Scotland. As set out in our draft Energy Strategy and Just Transition Plan, significant growth in renewables, storage, hydrogen and carbon capture provide the best pathway to net zero by 2045 and will deliver a climate friendly energy system that delivers affordable, resilient and clean energy supplies for Scotland's households, business and communities.

Member states of the EU have a wide range of views on the use of nuclear energy, and we are aware that policy is evolving across member states. In April, Germany shut down the last of its three nuclear power plants, joining other member states which have no nuclear power stations and remain opposed to nuclear power, including Austria, Denmark, Ireland, Italy, Estonia, Latvia, Luxembourg, Malta and Portugal. Several other member states, including Spain, have plans to phase out nuclear power. In contrast, Finland has recently constructed the first new nuclear reactor in Europe in 16 years.

According to The International Atomic Energy Agency’s Power Reactor Information System (PRIS), the average lifetime capacity factor for Torness Nuclear Power Station was around 75% for Unit 1, and 74% for Unit 2 in 2022.

Modelling undertaken as part of the evidence base underpinning our draft Energy Strategy and Just Transition Plan, estimated electricity generation capacity and demand in Scotland in 2030 according to a range of scenarios.

Across all three scenarios electricity generation capacity ranged between 20-41 GW (47-119 TWh) and electricity demand ranged from 48-55 TWh.

The Massachusetts Institute of Technology (MIT) study considers the potential contribution nuclear can make as a dispatchable low-carbon technology.

The report states: “The fundamental problem is cost. Other generation technologies have become cheaper in recent decades, while new nuclear plants have only become costlier.”

As set out in our draft Energy Strategy and Just Transition Plan, rather than new nuclear, it is significant growth in renewables, such as wind power, as well as investment in storage, hydrogen and carbon capture which will provide the best pathway for Scotland to achieve net zero by 2045.

Across the four quarters of 2022 the average capacity factors of onshore and offshore wind were as follows:

1. Onshore wind: 28.2%

2. Offshore wind: 36.0%
