    Modified UK National Implementation Measures for Phase III of the EU Emissions Trading System As submitted to the European Commission in April 2012 following the first stage of their scrutiny process This document has been issued by the Department of Energy and Climate Change, together with the Devolved Administrations for Northern Ireland, Scotland and Wales. April 2012 UK’s National Implementation Measures submission – April 2012 Modified UK National Implementation Measures for Phase III of the EU Emissions Trading System As submitted to the European Commission in April 2012 following the first stage of their scrutiny process On 12 December 2011, the UK submitted to the European Commission the UK’s National Implementation Measures (NIMs), containing the preliminary levels of free allocation of allowances to installations under Phase III of the EU Emissions Trading System (2013-2020), in accordance with Article 11 of the revised ETS Directive (2009/29/EC). In response to queries raised by the European Commission during the first stage of their assessment of the UK’s NIMs, the UK has made a small number of modifications to its NIMs. This includes the introduction of preliminary levels of free allocation for four additional installations and amendments to the preliminary free allocation levels of seven installations that were included in the original NIMs submission. The operators of the installations affected have been informed directly of these changes. The allocations are not final at this stage as the Commission’s NIMs scrutiny process is ongoing. Only when all installation-level allocations for an EU Member State have been approved will that Member State’s NIMs and the preliminary levels of allocation be accepted.

  • Biomass Task Force Report to Government • October 2005 Standing – Nikki Macleod, David Clayton, Rebecca Cowburn
    Biomass Task Force Report To Government • October 2005 Standing – Nikki MacLeod, David Clayton, Rebecca Cowburn. Seated – John Roberts CBE, Sir Ben Gill CBE, Nick Hartley FOREWORD by Sir Ben Gill The challenge set for the Task Force was to make proposals to optimise the contribution of biomass to a range of targets and policies set by the Government. In setting out the case for biomass we noted that the Energy White Paper contained clear aspirations about renewable energy, security of supply, competitiveness and fuel poverty. The Government also has the important objectives of sustainable development and sustainable farming, forestry and woodland management. Taken together, all of these aims can deliver environmental improvement and also economic benefit particularly in rural and other areas. Our work has shown that the potential of biomass is significant. We have taken the real contribution it can make to the climate change agenda as the primary driver. In putting in place a programme of actions to deliver biomass energy there is a critical need for a strategic approach by the Government to enable the potential to be exploited. We focus on the fact that in spite of more than one-third of primary energy being used for heat there has been a lack of recognition of the role of renewable heat in policy delivery. The approach could be characterised as - no targets; no concerted policy; no strategy; and, limited support for development. So far as DTI’s Energy White Paper is concerned there was a missed opportunity to develop targets for renewable heat and this has perpetuated an inconsistency of approach in Government and in the Regions.

  • Technical Chapters a Cars II
    Part III Technical chapters A Cars II We estimated that a car driven 100 km uses about 80 kWh of energy. Where does this energy go? How does it depend on properties of the car? Could we make cars that are 100 times more efficient? Let’s make a simple cartoon of car-driving, to describe where the energy goes. The energy in a typical fossil-fuel car goes to four main destinations, all of which we will explore: 1. speeding up then slowing down using the brakes; Figure A.1. A Peugot 206 has a drag coefficient of 0.33. Photo by 2. air resistance; Christopher Batt. 3. rolling resistance; The key formula for most of the calcula- tions in this book is: 4. heat – 75% of the energy is thrown away as heat, because the energy- 1 kinetic energy = mv2. conversion chain is inefficient. 2 For example, a car of mass m = 1000 kg Initially our cartoon will ignore rolling resistance; we’ll add in this effect moving at 100 km per hour or v = later in the chapter. 28 m/s has an energy of Assume the driver accelerates rapidly up to a cruising speed v, and 1 mv2 390 000 J 0.1 kWh. maintains that speed for a distance d, which is the distance between traffic 2 ≃ ≃ lights, stop signs, or congestion events. At this point, he slams on the brakes and turns all his kinetic energy into heat in the brakes. (This vehicle STOP v STOP doesn’t have fancy regenerative braking.) Once he’s able to move again, he accelerates back up to his cruising speed, v.

  • Appeal by ECO2 Against Mid Suffolk District Council's Refusal of Planning
    Dear Sir/Madam, Re: Appeal by ECO2 against Mid Suffolk District Council’s refusal of planning permission for a Mendlesham Renewable Energy Plant, Norwich Road, Wetheringsett-Cum-Brockford, Appeal Reference APP/W3520/A/14/2211941 Biofuelwatch objected to ECO2’s planning application for a biomass power station near Mendlesham in May 2012 and submitted a response to subsequent statements by the developer in April 2013. We maintain our opposition to the development on the grounds specified at those times, but would like to submit further information in relation to this Appeal. Low efficiency: As we pointed out previously, this power station proposal was not accompanied by a CHP Feasibility Study and we understand that there is no potential heat customer located nearby. To our knowledge, all successful CHP schemes in the UK have been designed around one or several heat customers and none were originally designed as electricity-only plants and then retrofitted. ECO2 claim in their planning application that the power station would be 34% efficient. This is far below the 70-80% efficiency commonly reached for biomass combined heat and power plants across Europe. Nonetheless, we believe that the 34% efficiency claim – for which the company provides no evidence - is likely over-optimistic and unrealistic in this case: + ECO2’s Environmental Statement, dated February 2012, shows that combustion grate, rather than fluidised bed technology will be used. The European Commission’s Reference Document on Best Available Techniques for Large Combustion Plants1 is based on inputs from “more than 60 experts from Member States, industry and environmental NGOs”. It states that biomass grate firing has the lowest electric efficiency of biomass combustion technologies – around 20% (Table 5.3.1).

  • Agenda Item No. 10
    AGENDA ITEM NO. 10 MAIN CASE Proposal: Application under Section 73 of The Town and Country Planning Act 1990: Variation of condition 28 planning application E/95/0897/FUL - "Requirement to provide for covered loads (straw) into the station" Location: EPR Elean Power Station Elean Business Park Sutton Ely Cambridgeshire CB6 2QE Applicant: EPR Elean Power Station Agent: Reference No: 09/00027/VAR Case Officer: Jacqueline Harding Parish: Sutton Ward: Sutton Ward Councillor/s: Councillor Read Councillor Peter Moakes Date Received: 15 January 2009 Expiry Date: 12 March 2009 [H401] 1.0 EXECUTIVE SUMMARY 1.1 When the Elean Straw Burning Power Station was first granted approval, there was a concern regarding the transportation of the straw to the site, both in relation to the routes through nearby villages, and the fact that material from the lorries can be blown onto the roads. To meet this concern, a condition (28) was attached to the permission that required:- “The plant shall not be commissioned until a scheme for covered loads and the containment of windblown straw (and other fuel matter) has been submitted to and agreed in writing by the Local Planning Authority,” and a Section 106 was drawn up, inter alia, to monitor straw debris for twelve months and attempt to achieve a routing agreement together with the covering of loads. 1.2 In practice, neither the condition nor the Section 106 has been found to be robust in achieving its objective. It is important that any condition is in compliance with Circular 11/1995, and is enforceable. As a result of consultation with County Highways, and taking into account Health and Safety matters, the variation of the condition can reasonably be met by the substitution of two new conditions that require the operators Agenda Item 10 – Page 1 of the site to carry out certain actions and record them.

  • East of England Commentary 2011/2012
    East of England Commentary 2011/2012 This report includes data collected from the Farm Business Survey for the 2011 to 2012 financial year, relating to the 2011 crop harvest. Please note that due to a change in farm classification, results from the 2010/2011 and 2011/2012 years are not directly comparable with results prior to that date. Please see the explanatory document at http://www.defra.gov.uk/statistics/foodfarm/farmmanage/fbs/ for further details of these changes. The Farm Business Survey is conducted on behalf of, and financed by the Department for Environment, Food and Rural Affairs, and the data collected in it are Crown Copyright. Nature of Farming in the region The majority of the farmed area of the East of England is focussed on combinable crop production due to its climate, landscape and suitability of soils. In the northern part of the region, fenland and silt soils permit production of sugar beet, potatoes and field scale vegetables. Pig and poultry production is important in rural East Anglia due to the proximity of production of grain for feed. Horticultural production is concentrated in the proximity of London and to the north of the region. Grazing livestock utilise grassland throughout the East of England with higher numbers in the area of the Norfolk Broads and in Hertfordshire. The Norfolk Broads are the East of England’s National Park. This designation covers two per cent of the East of England. Areas of Outstanding Natural Beauty (AONBs) account for six per cent of the region (15 per cent across England)1.

  • Biomass and Biofuels Programmes
    RPA Biomass Conference & Renewables East Biofuels Conference 19th & 20th July 2005 Queens’ College, Cambridge Following the huge success of the RPA’s first biomass conference, held in York last year, we are pleased to announce this years event, to be held on Tuesday 19th July in Cambridge. There will be an exhibition alongside the conference, which will be followed by a drinks reception and evening dinner, co-hosted with Renewables East. The RPA Biomass Resource Group will meet on the following morning, and a complimentary site tour of Elean Power Station, Ely will take place on the Wednesday afternoon. This year we are delighted to be collaborating with Renewables East. Renewables East, the renewable energy agency for the East of England in association with the HGCA, will be hosting their Biofuels conference on Wednesday 20th July. This event will move forward the debate on biofuels with a strong emphasis on the commercial and business issues surrounding the development of a UK biofuel industry. The importance of global trade, world markets and their influence on a new UK industry will be tackled. There are excellent prospects for bioenergy in the East of England, and the combination of these two key events will make Cambridge the place to be for all those involved in the biomass sector. RPA Conference, members meeting and site visit The RPA Biomass Conference will include keynote speeches from Sir Ben Gill and Lord Bach, as well as sessions on project development, mitigating risks in the energy crop supply chain, and the implications of the 2005/6 Review of the Renewables Obligation.
