EXECUTIVE SUMMARY The scope of this review was confined to the Lincs Export Cable installation costs and involved: • An examination into the investigations undertaken as part of the pre-construction works regarding the options considered for the connection point, and an independent view on rationale for the selection of the connection of Walpole; • An outline of where export cable installation costs have increased since the indicative valuation was set in July 2011; • A rationale for each of the costs increases since the indicative was set in July 2011, and an independent view on the justification of these cost increases; and • A summary and description of outstanding claims and contract variations that have arisen outside of the basic contract price and a view on the claim levels in relation to the work and efficiency of the project management of the contract works. The analysis covers documentation provided to the consultant between 21 December and 28 January 2013. In addition there were follow up discussions facilitated by OfGem with Centrica and a telephone conversation with Natural England. The events generated further documentation to which commentary has been added in this report. During the review Tractebel UK engaged closely with the developer and there was a constant communication and data-exchange between both parties. Having taken into account all of the information and data provided,

  • A Theoretical Framework for Improving Energy Justice in the UK
    Watching the Wind Blow By: A Theoretical Framework for Improving Energy Justice in the UK Rupert Cope Bournemouth University Faculty of Science and Technology the award for which the degree of Masters by Research (MRes) is submitted in partial fulfilment of its requirements Submitted September 2018 Copyright Statement This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with its author and due acknowledgement must always be made of the use of any material contained in, or derived from, this thesis. 1 | P a g e Abstract For over thirty years the Brundtland’s Commission’s definition has been widely accepted as the general definition of what sustainable development is. However, there is increasing academic discourse suggesting that aspects of the Brundtland’s definition are inadvertently limiting the potential of contemporary sustainability from the perspectives of both horizontal and vertical actors both nationally and internationally. Through a lack of a clear measuring tool of what effective sustainable development is under Brundtland’s definition, differing interpretations (either deliberately or subconsciously) can be made leading to competing interests between the environmental, economic and social pillars of the based on the interpreter’s subjective interests. Using an overarching definition of SD that overlooks or simplifies varying wants and needs of individuals and groups within a single society this can result in the production of unbalanced policy measures. These unbalanced policies then hamper significant advancement of sustainable technology implementation as they fail to adequately reflect these varied and competing needs. The UK is demonstrating such scenarios in which the skewed application of sustainable development is creating growing numbers of injustice.

Throughout the year, the Committee challenged our current performance and debated areas of future activity across a range of critical business issues. Through this continual process of improvement, I have confidence that we are making good progress in developing the necessary structures and processes, allied to a management commitment that will build a sustainable and environmentally aware business for the future. In this report, you can read about our initiatives and performance over the year, as well as our forward- looking plans for 2009 and beyond.

  • ENERGY - Some Macro and Micro Aspects of Spatial Planning1
    ENERGY - Some Macro and Micro Aspects of Spatial Planning1 I. INTRODUCTION (i) Scope Policy approaches to the finding, generation and conservation of energy are enormous in scope. The issues which touch upon the policy approaches are global in nature and are significant drivers of international political events. Energy security is a primary consideration of all western governments and is a significant factor in political stability in developing countries and of course, in the oil producing countries. Likewise, questions of food security are closely related to fossil fuel availability and price. Political and social unrest in respect of both environmental and economic consequences of energy and food security issues has been evident in recent years. Moreover, the policy drivers in respect of energy generation and conservation are intimately and closely linked to policy measures to address climate change. If there were one word which was most appropriate to start a discussion on how to ‘put the world to rights’, then “energy” might be that word. In this paper I seek to set out something of the broad context which gives rise to a range of domestic policy approaches which materially and significantly affect land use in planning decisions. I seek to identify the range of impacts which energy related policies have upon planning decisions and then identify the present position and trends in respect of energy generation and design. 1 Paper published in the journal of the United Kingdom Environmental Law Association, May 2011 2 (ii) Context - Economic Growth and Sustainable Development The tension between economic growth and development which is sustainable has long been identified2.
