  • Press Release 4Th May 2018
    Press release 4th May 2018 Electric Mountain Visitor Centre Holds Public Exhibition for Refurbishment Plans First Hydro Company, the owner of the Electric Mountain Visitor Centre, has outlined its plans to refurbish the centre in Llanberis. The proposals were presented at a public exhibition held at the Electric Mountain Visitor Centre on 17th April. Local residents and other stakeholders were invited to view information on the proposals, meet representatives of First Hydro and ask questions about the project. First Hydro, which is 75% owned by ENGIE and 25% owned by Brookfield Renewable Partners, operates the Dinorwig Power Station (1,728 MW) and Ffestiniog Power Station (360 MW), as well as the Visitor Centre. John Armstrong, First Hydro Station Manager, said: ‘We were delighted to present our plans for the refurbishment of the Electric Mountain Visitor Centre to the local community. The aim of the new building is to deliver an engaging and attractive visitor experience, providing user- friendly resources that will appeal to tourist and education visitors alike. There will also be much- improved facilities for the community to use. Drawing on ENGIE’s regeneration capabilities, the new building will be sustainably designed, energy efficient and in keeping with the local environment and landscape. We look forward to continuing our public engagement through the construction process and beyond.’ A planning application has been submitted to Gwynedd Council, and the refurbishment work will commence once planning permission has been granted. It is anticipated that the construction of the new centre will take between 12 and 18 months. Last year ENGIE also announced plans to invest £50 million in a refurbishment of two units of the Ffestiniog Power Station, to extend the life of the units by a further 20 years.

    A Study of Hydroelectric Power: From a Global Perspective to a Local Application Prepared by: Duane Castaldi Eric Chastain Morgan Windram Lauren Ziatyk Prepared for the 2003 Center for Advanced Undergraduate Studies and Experience From Industrial Revolution to Industrial Ecology: Energy and Society College of Earth and Mineral Sciences The Pennsylvania State University ABSTRACT As energy becomes the current catchphrase in business, industry, and society, energy alternatives are becoming increasingly popular. Hydroelectricity exists as one option to meet the growing demand for energy and is discussed in this paper. Numerous consideration factors exist when building hydropower plants; whether the concerns are global or local, each has been measured when discussing this renewable energy source. From environmental and economic costs of constructing such plants to proposing the addition of hydropower generating capabilities in Pennsylvania, the authors have used personal experience from field studies and intensive research to cover the topic of hydroelecticity.

In the most simplistic terms, water falls due to gravity, which causes kinetic energy to be converted into mechanical energy, which in turn can be converted into a useable form of electrical energy.

  • Regulation of the Uk Electricity Industry
    INDUSTRY BRIEF REGULATION OF THE UK ELECTRICITY INDUSTRY 2002 edition Gillian Simmonds REGULATION OF THE UK ELECTRICITY INDUSTRY 2002 edition CRI Industry Brief Gillian Simmonds Desktop published by Jan Marchant © The University of Bath All rights reserved ISBN PREFACE The CRI is pleased to publish the 2002 edition of its industry brief on the Regulation of the UK Electricity Industry, having updated it for developments since the 1998 edition. It has been prepared by Gillian Simmonds, a Research Officer at the CRI, and supersedes the first edition which was prepared by Carole Hicks, then a Research Officer at the CRI. The brief is part of a set of CRI industry briefs for the utilities and network industries, covering water, energy, transport and communications. The structure and regulation of the electricity industry has changed considerably since 1998, including developments such as the new electricity trading arrangements (NETA), competition in electricity supply and the Utilities Act 2000, which created, amongst other things, separate, independent arrangements for consumer representation (energywatch) and the Gas and Electricity Markets Authority (the ‘Authority’), which took over the powers and duties of the Director General. The new 2002 edition is, therefore, substantially a new document, rather than a ‘revision’. The CRI would welcome comments on the Brief, which can be taken into account as CRI Industry Briefs have to be updated from time to time in line with developments in the Industry, and will be published as a ‘revised’ or subsequent ‘edition’. Comments should be addressed to: Peter Vass Director – CRI School of Management University of Bath Bath, BA2 7AY The CRI publishes work on regulation by a wide variety of authors, covering a range of regulatory topics and disciplines, in its International, Occasional and Technical Paper series.

It considers the effects of the proposed policy at a national level and the sites to be assessed for their suitability for the deployment of new nuclear power stations by 2025. These strategic appraisals are part of an ongoing assessment process that started in March 2008 and, following completion of this AoS, will continue with project level assessments when developers make applications for development consent in relation to specific projects. Applications for development consents to the Infrastructure Planning Commission will need to be accompanied by an Environmental Statement having been the subject of a detailed Environmental Impact Assessment.

  • Scale and Environmental Issues. Pumped Hydroelectric and Compressed Air Energy Storage
    Mechanical Systems for Energy Storage – Scale and Environmental Issues. Pumped Hydroelectric and Compressed Air Energy Storage David J. Evans*, British Geological Survey, Keyworth, Nottingham, England, Gideon Carpenter, Evidence, Policy and Permitting Directorate, Natural Resources Wales, Pembrokeshire, Wales, and Gareth Farr, British Geological Survey, Cardiff, Wales. Corresponding contributor. Email: [email protected] Abstract This chapter introduces large‐scale utility (bulk) energy storage in the form of pumped hydroelectric (PHS) and compressed air energy storage (CAES). Both are mechanical energy storage technologies, converting electrical energy into potential energy and both fall into the category of grid‐scale, energy management. Brief reviews and discussions relating to the general operational aspects, legislative and environmental aspects of the two storage types are provided in the context of UK development. Both storage technologies offer the potential for better integration and penetration of renewable electricity sources and the reduction of greenhouse gas (GHG) emissions. 1 Introduction International, national and regional energy policies aim to promote the use of renewable‐ based electricity (RES‐E) to reduce carbon emissions and secure local power supplies. The European Union has set ambitious greenhouse gas (GHG) emission reduction targets of 20% by 2020 and 80% by 2050.1 In addition, the United Nations set a target of doubling the renewables share in the global energy mix by 2030, from the 18% seen in 2010, to 36% in 2030.2 The transition to and increasing the use of renewable energies such as wind and solar, which are by nature intermittent, will therefore introduce increased natural variability into electricity generation and capacity. To meet patterns of demand that do not follow such variations in generation, there will be a need for fast‐ramping, back‐up generation, supported by reliable forecasting and, importantly, increased bulk, grid‐scale storage capacity for electricity generated from renewables.
