Executive summary 1.1 This document is the Government’s response to its August 2011 statutory Consultation on draft licence conditions and technical specifications for the roll-out of smart metering equipment1. The Consultation sought views on the draft licence modifications that provide the first elements of the regulatory framework for the roll-out, as well as related policy issues. Views were also sought on the Government’s approach to developing the Smart Metering Equipment Technical Specifications (SMETS) to which smart metering systems2 must comply to fulfil the suppliers’ roll-out obligation and on a number of specific design issues. The Government’s response sets out the regulatory framework for the roll-out of smart metering systems and the approach that will be taken on the SMETS, including a number of decisions on specific technical issues. 1.2 The Government has already determined that the roll-out should be completed in 2019; the Consultation explored what specific date in 2019 should be set in the licence conditions. Respondents expressed concern about defining a completion date early in 2019, reflecting the complexity of the roll-out, the time needed to deliver the roll-out in a way that supports benefits realisation, and the impact on delivery if there are delays in delivering key activities of the Smart Metering Programme (Programme). To balance the Government’s desire to deliver the benefits of smart metering for consumers as early as possible against the risks to these benefits if the roll-out is rushed, the Government has set an end-date of 31 December 2019. 1.3 A major focus of the Consultation was the SMETS. Views were invited on the Government’s general approach to developing the SMETS and on the Industry’s Draft Technical Specifications (IDTS) which the Government proposed would be the basis of the SMETS. Attention was drawn by respondents to the extent of the challenge in developing these specifications and support was demonstrated for a phased introduction of the SMETS to avoid roll-out being delayed until all the complex technical issues are resolved, in particular in relation to communication standards for the Home Area Networks (HANs) and Wide Area Networks (WANs). 1.4 The Government believes that it is important that the policy and regulatory framework for the roll-out of smart metering enables industry participants to manage the costs of preparing for the Mass roll-out stage and making the transition to the enduring arrangements in the most efficient way. In 1 Smart Metering Implementation Programme – A consultation on draft licence conditions and technical specifications for the roll-out of gas and electricity smart metering equipment. www.decc.gov.uk/en/content/cms/consultations/cons_smip/cons_smip.aspx 2 ‘Smart Metering Systems’ is the term used in this document to refer in general terms to the collection of individual pieces of smart metering equipment that will be installed in consumer premises in the smart metering roll-out. Smart Metering Systems is a new term introduced in the Roll-out licence conditions (see annexes 1 and 2). 5 Government response to smart metering roll-out consultation recognition of the time it will take to resolve all the technical challenges involved in developing the SMETS, the Government has chosen an evolutionary approach to the development of the SMETS. The first iteration, which accompanies this document, will provide for core functionality and functional interoperability of smart metering systems. This confirms the position set out in the December 2011 revised Programme Delivery Plan3 on the development of the SMETS. The initial version of the SMETS will be made available on the DECC website. 1.5 Although a majority of respondents to the Consultation believed that the roll- out licence conditions as drafted and the associated technical specification for metering equipment would support the Programme’s objectives, the Government has considered whether on its own, the requirement for smart metering to comply with the SMETS would provide the necessary certainty that

  • Etsu/K/Bd/00187/Rep Establishing a Local
    ESTABLISHING A LOCAL AUTHORITY MARKET FOR GREEN POWER ETSU/K/BD/00187/REP Contractor ESD Ltd Prepared by A Turnbull N Evans The work described in this report was carried out under contract as part of the New and Renewable Energy Programme, managed by the Energy Technology Support Unit (ETSU) on behalf of the Department of Trade and Industry. The views and judgements expressed in this report are those of the contractor and do not necessarily reflect those of ETSU or the Department of Trade and Industry First Published 1999 © Crown Copyright 1999 EXECUTIVE SUMMARY The aim of this project is to establish how to maximise the potential local authority (LA) market for green power by examining the procurement and supply issues, and identifying ways to overcome the potential barriers faced both by LAs (as purchasers) and potential green electricity suppliers. To do this, it is important to understand how LAs normally procure goods and services and how power suppliers normally supply electricity. Once these two processes are understood, it is much easier to understand the issues for a LA wishing to procure green energy and for a power supplier wishing to provide green electricity, instead of buying or supplying conventional electricity. The first stage of the project was to assess the procurement processes of the LAs. This review of LA energy procurement processes resulted in a report covering the following: • background to LA structure and how this may influence procurement practices; • the liberalised market opportunities for renewable energy; • current purchasing arrangements, particularly the important role of the Standing Order; • data requirements for LAs preparing tenders; • options for, and barriers to, purchasing green energy; • conclusions, covering how the current procurement practices can be adapted to promote the procurement of green energy.

In accordance with our role as provider of the Data Transfer Service (DTS) to the GB electricity market we have focused our response on those areas most closely aligned with our experience, knowledge and core competencies. Where are the Delays in Supplier Switching? The issues surrounding the duration of the supplier switching process identified by Ofgem in this consultation are clearly not confined to ‘central’ systems. From an electricity market perspective, ElectraLink considers that it is the processes and procedures set out in the Master Registration Agreement (MRA) that primarily determine the time taken to affect a Supplier event rather than the technology that underpins these processes. In particular, delays to switching are not related to the time taken to exchange data on the DTS between parties. The DTS transfers data between electricity market participants in minutes and can be re-configured to accommodate industry process changes, including message prioritization at either the application layer or the network layer to accelerate transfers to seconds if required. ElectraLink Ltd Registered No: 3271981. VAT Registration No: 698 2336 89.

  • RCEF) Stage 1 Feasibility Study - Final Report
    Energy Local Bridport Rural Community Energy Fund (RCEF) Stage 1 Feasibility Study - Final Report 1) Introduction and background Dorset Community Energy (DCE) was initially established in 2013 with support from Dorset County Council. Since registration as a not-for-profit Community Benefit Society DCE has raised approximately £1m from 195 shareholders, of whom 75% live in Dorset. A total of 1,200kW of community-financed solar panels have been installed the roofs of 22 public buildings since 2015, including schools, community halls and more recently 3 hospitals. The sites are currently collectively saving approximately £45,000 per year in free or low cost solar electricity. However with the closure of the Feed-in Tariff on 1st April 2019 the DCE directors started to seek alternative business models for community-financed renewable energy. A meeting was held with Energy Local CIC (winners of an Ashden Award in 2018 for an innovative project in Bethesda, N. Wales involving supply of electricity through the grid from a local 100kW hydro- electric generator to around 100 local households at lower cost than standard grid electricity). Energy Local CIC partnered with Co-operative Energy who managed the installation of smart meters, together with metering and billing and back-up supply when there was insufficient local hydro generation. Following this meeting Energy Local CIC agreed to support a local electricity supply project in Bridport, Dorset, based on selling generation from an existing 50kW farmer-owned wind turbine in the Bridport electricity substation area. Training was provided in October 2019 and the Energy Local Bridport project was launched with volunteer support from Dorset Community Energy in early January 2020.

In domestic scenarios (profile Classes 1-4) with modern Smart Metering Equipment Technical Specification (SMETS) compliant metering systems, Import and Export of Electricity can be managed by the same meter. Different Suppliers can be responsible for the Imported energy and the Exported energy. The Import Supplier is responsible for; 1. Supply of energy to the customer 2. Asset rental payments for the Meter 3. Maintenance and repair of the Meter 4. Appointment of the Meter Operator Agent (MOA) The Export Supplier is responsible for; 1. Purchase of surplus energy from the customer Ecotricity cited several examples where they have struggled to correctly identify the appointed MOA.
