Signed ………………………………………… (candidate) Date ………………………… II Abstract Demand response (DR) is able to contribute to the secure and efficient operation of power systems. The implications of adopting the residential DR through smart appliances (SAs) were investigated from the perspective of three actors: customer, distribution network operator, and transmission system operator. The types of SAs considered in the investigation are: washing machines, dish washers and tumble dryers. A mathematical model was developed to describe the operation of SAs including load management features: start delay and cycle interruption. The optimal scheduling of SAs considering user behaviour and multiple-rates electricity tariffs was investigated using the optimisation software CPLEX.
  • Open Letter – Notifying of Our Intention to Launch a Project to Protect Consumers from Back Billing

    Open Letter – Notifying of Our Intention to Launch a Project to Protect Consumers from Back Billing

    Suppliers, consumer groups and other interested parties BY EMAIL Date: 3 April 2017 Dear colleagues Open letter – notifying of our intention to launch a project to protect consumers from back billing The purpose of this letter is to announce that we are launching a project to examine the regulatory framework governing back billing.1 Our minded-to position is to introduce new licence obligations to strengthen consumer protections in this area. The back-billing principle was introduced in 2007 and states that, if a supplier is at fault, they will not seek additional payment for unbilled energy used more than 12 months prior to the error being detected and a corrected bill being issued.2 We view this as an essential consumer protection and a minimum standard that we expect all suppliers to apply. The principle was introduced through self-governance; the suppliers active in the domestic retail market (at the time of introduction) committed to apply it and enshrined it in their own policies. However, in the ten years since it was introduced the market has changed markedly. There are now over fifty active suppliers in the retail market; in 2007 there were just eleven. We are not confident that the principle is being applied consistently across the market and are concerned that not all suppliers have appropriate back billing arrangements in place. When the principle was originally introduced, we stated that we would regulate to protect consumers if we became aware that the principle was not being applied universally.3 Given the reasons outlined, we are launching a project with the aim of protecting consumers from excessive back billing time limits.
  • Greenwashing Vs. Renewable Energy Generation

    Greenwashing Vs. Renewable Energy Generation

    Greenwashing Vs. Renewable energy generation: which energy companies are making a real difference? Tackling the climate crisis requires that we reduce the UK’s carbon footprint. As individuals an important way we can do this is to reduce our energy use. This reduces our carbon footprints. We can also make sure: • All the electricity we use is generated renewably in the UK. • The energy company we give our money to only deals in renewable electricity. • That the company we are with actively supports the development of new additional renewable generation in the UK. 37% of UK electricity now comes from renewable energy, with onshore and offshore wind generation rising by 7% and 20% respectively since 2018. However, we don’t just need to decarbonise 100% of our electricity. If we use electricity for heating and transport, we will need to generate much more electricity – and the less we use, the less we will need to generate. REGOs/GoOs – used to greenwash. This is how it works: • If an energy generator (say a wind or solar farm) generates one megawatt hour of electricity they get a REGO (Renewable Energy Guarantee of Origin). • REGOs are mostly sold separately to the actual energy generated and are extremely cheap – about £1.50 for a typical household’s annual energy use. • This means an energy company can buy a megawatt of non-renewable energy, buy a REGO for one megawatt of renewable energy (which was actually bought by some other company), and then claim their supply is renewable even though they have not supported renewable generation in any way.

    Open Letter: Cooperation with Switching Programme Governance Arrangements

    Email: [email protected] Date: 15 January 2019 Dear Colleagues, Open letter: Cooperation with Switching Programme Governance Arrangements I am writing today to set out the baselined governance arrangements we are establishing to oversee the delivery phase of the Switching Programme and to invite you to provide feedback on the nominated representatives to participate in the new groups. Attached as an annex to this letter is a pack of information explaining these arrangements and the nominations received thus far. I would be grateful if you could respond by 25 January with any additional feedback and for parties still to nominate their representative, with the names and details of their representative to [email protected]. Overview of new governance arrangements At the Switching Programme Delivery Group on the 11 September, we set out our initial proposal for changes to the governance of the Switching Programme for the delivery phase. These changes are designed to improve the governance of the programme, to provide more efficient mechanisms to engage the right people, and facilitate quicker consultation and decision making during the DBT Phase of the Programme. Following the initial circulation of the proposed governance structure we received feedback that the level of supplier representation on the groups was not sufficient. We have listened to the feedback provided, and revised the governance structure on the Implementation Group and Delivery Group to address this feedback. The revised representative structure is set out below. The Terms of Reference for these groups will be made available in the coming weeks. We have allocated suppliers into Large, Medium and Small categories.

  • Auto-Rollover Remedy

    Auto-Rollover Remedy

    Appendix 17.2: Auto-rollover remedy 1. This appendix, which relates to the auto-rollover remedy, first sets out parties’ initial comments to the Remedies Notice. Thereafter, it lists the detailed submissions (from parties), which we received before the publication of the provisional decision on remedies. Finally, we review the grounds for objections under which suppliers can object to a transfer occurring. 2. We have listed the parties’ responses to the provisional decision on remedies in the main body relating to microbusiness remedies. We note that all the parties that responded to the provisional decision on remedies supported the remedy and its design, except for Haven Power. Responses to the Remedies Notice 3. In the Remedies Notice, we consulted on a remedy that stipulated ‘introduction of a new requirement into the licences of retail energy suppliers that prohibits the inclusion of terms that permit the auto-rollover of microbusiness customers on to new contracts with a narrow window for switching supplier and/or tariff.’ 4. In this section we set out a summary of the responses to the Remedies Notice. The responses below can be found in full on our website. The Six Large Energy Firms 5. Centrica told us that it believes that the ending of auto-rollover contracts (with fixed-term Rollover Periods) would be beneficial to microbusiness customers and would help generate trust and engagement in the microbusiness segments. Since ending auto-rollover contracts (with fixed-term Rollover Periods), Centrica said that it had seen increased competitive forces as a result of the removal of the narrow window of opportunity for switching, and that would help support the right kind of conditions for PCWs to emerge.
