Whatever next?

By Dave Elliott

Simon Taylor’s The Fall and Rise of Nuclear Power in Britain’  (UIT Cambridge) is a readable scamper through the history of the UK nuclear programme, warts and all, with much detail on who did what. The government’s Chief Scientists, Sir David King and Sir David MacKay, are seen as having played key roles in recent years, and Taylor seems to accept the resultant official view that renewables won’t be sufficient: During those inevitable dreary November days when the UK has grey skies and no wind, it will be thermal power, whether gas-fired or nuclear, which keeps the UK moving, lit and warm. Nuclear therefore has a place in the mix for the foreseeable future’.

Labour’s 65% renewables by 2030 plan

By Dave Elliott

Labour’s new Environment and Energy policy aims to get 65% of UK electricity from renewables by 2030 and pioneer a ‘democratic, community-led system of energy supply’. That is well ahead of what might happen under current plans, and includes 47GW of offshore wind, 21GW of onshore wind (up from around 5GW and 10GW at present, respectively) and 25GW of PV solar (up from 12GW now), but is presented as being possible since it would involve new forms of decentralised project development, alongside more conventional ‘top down’ corporate projects, suitably accelerated.

Nuclear Prospects

By Dave Elliott

‘Supporting early new nuclear projects could lead to higher costs in the short term than continuing to support wind and solar. The cost competitiveness of nuclear power is weakening as wind and solar become more established’. So said the National Audit Office in its recent review of UK nuclear policy: www.nao.org.uk/report/nuclear-power-in-the-uk 

It did, however, say that ‘the decision to proceed with support for nuclear power therefore relies more on strategic than financial grounds: nuclear power is needed in the supply mix to complement the intermittent nature of wind and solar’. That’s an odd view. As the NAO admitted, nuclear is inflexible and cannot balance variable renewables, and the ‘security of supply’ argument may not be as strong as is sometimes claimed. (more…)

Delivering the goods – clean energy policy

By Dave Elliott

‘Delivering Energy Law and Policy in the EU and the US’, edited by Raphael J. Heffron, Gavin F. M. Little and published by Edinburgh University Press, is a compilation of short chapters from a very wide range of academics that reviews the state of play in the energy policy field in the West. As the editors note, one issue that emerges is the slow progress in relation to the adoption of new cleaner, greener energy options, which they say ‘encourages incumbents and in essence maintains their status’.  The reviews in this book look at what has been done so far and at what could be done to move things on in the future, via new policies and legislation.

Russia could win

By Dave Elliott

Renewable energy could supply Russia and Central Asian countries with all the electricity they need by 2030, and cut costs significantly, according to a new study from Lappeenranta University of Technology (LUT) in Finland. It says that renewable energy is the cheapest option for the region and could make Russia very energy competitive in the future. A 100% renewable energy system for Russia and Central Asia would, it claims, be roughly 50% lower in cost than a system based on the latest European nuclear technology or carbon capture and storage.

After Hinkley

By Dave Elliott

Battles continue over the economic viability of the proposed £18bn Hinkley nuclear project, with EDF still saying it can go ahead, despite the resignation of two key senior executives, opposition from the French trade unions and even doubts now emerging from the French Government. Energy minister Ségolène Royal said: ‘This project must offer further proof that it is well-founded and offer a guarantee that the investment in this project will not dry up investments that must be made in renewable energies.’  It is interesting then that EDF’s recent R&D Paper ‘Technical and Economic Analysis of the European Electricity System with 60% RES’, by Alain Burtin and Vera Silva, looks at an EU future dominated by renewables, with nuclear only playing a moderate role, 90GW total.

UK Energy and the EU: integration or isolation

By Dave Elliott

The UK may be island based but, as renewables expand, it will need more grid links to the continent for balancing and trade. It may have a net surplus and so could do very well selling it over supergrid interconnector links to EU countries less well endowed with renewables. The UK’s National Infrastructure Commission (NIC), which seems to be taking a leading role in energy system planning, said in its recent report ‘Smart Power’, that interconnection, along with storage and demand flexibility ‘could save consumers up to £8 billion a year by 2030, help the UK meet its 2050 carbon targets, and secure the UK’s energy supply for generations’.

Energy system integration costs cut

By Dave Elliott

Imperial College London and the NERA consultancy have produced studies of energy system integration costs and grid balancing options for the government’s advisory Committee on Climate Change. They focus on flexible generation and backup systems and conclude that ‘flexibility can significantly reduce the integration cost of intermittent renewables, to the point where their whole-system cost makes them a more attractive expansion option than CCS and/or nuclear’.

Small modular nuclear – is small beautiful?

By Dave Elliott

A new report ‘The role for nuclear within a low carbon energy system’ from the Energy Technologies Institute, claims that the UK could have 50GW of nuclear power plants by 2050, including Small Modular Reactors (SMRs). Although it says, due to basic economies of construction and operational scale, ‘large reactors are best suited for baseload electricity production’, it notes that, based on using existing sites, there is ‘an upper capacity limit in England and Wales to 2050 from site availability of around 35 GWe’, and it could be less (e.g. if CCS plants need some of the sites). However, there could be more room for small nuclear plants (under 300kW) on new sites, at least 21GW and in theory up to 63GW.

Go slow on renewables

By Dave Elliott

‘Moving too quickly to zero carbon energy risks driving the bills of hardworking people too high’. That, from Energy Secretary Amber Rudd, in a DECC Blog on August 11th , seems to be the view underlying the government’s renewable energy support cutbacks. In her speech to the Conservative Party Conference in October she said that ‘as we have already shown, we will be tough on subsidies’, but insisted that the policy was fair since it simply was aimed at ‘getting the balance right between supporting new, low carbon generation and protecting bill payers’: http://www.businessgreen.com/bg/news/2429010/rudd-hails-potential-for-uk-to-become-home-for-energy-innovation
