Enabling technology – Vision for consumers? OCTES Workshop 31st October 2012 Enabling technology – Vision for consumers? Vision of the future. A lot of talk of Smart home – conjunction of a number of technologies – Renewable energy decentralised generation Energy Efficency Energy storage technologies Next phase of the information revolution – internet of things Going from very small scale to very big scale – grid management that allows systems to dynamically adjust to meet the needs of all customers & grid upgrades to allow two way flows How much do householders change their behaviour?

Context Shift to a low carbon economy Climate change targets OCTES Workshop 31st October 2012 Context Shift to a low carbon economy Climate change targets Renewable energy targets Affordability Fuel poverty Security of supply Link to next slide: Smarter technologies and appliances are seen to have an important role to play in delivering demand reduction (which can help….to meet cc targets Climate Change 80% 2050 42% 2020 And annual targets too reduce fuel poverty, ensure that no-one in Scotland has to live in fuel poverty, as far as practicable, by 2016 (note: commitment reaffirmed in recent consultation on Scotland’s Sustainable Housing Strategy) DECC: ‘The roll out of smart meters will play an important role in Britain’s transition to a low-carbon economy and help us meet some of the long-term challenges we face in ensuring an affordable, secure and sustainable energy supply.’   Fuel Poverty Renewables the target is now 100% of gross electricity consumed in Scotland to come from renewable sources by 2020. Demand Reduction target to reduce end-use Scottish final energy consumption by 12% by 2020

Smarter technologies and appliances OCTES Workshop 31st October 2012 Smarter technologies and appliances Home Energy Management Systems Heating and Hot Water Electricity Provide customers with: greater control greater efficiency, and lower consumption The functionality of Home Energy Management products on the market today is diverse – ranging from basic energy usage displays at one end of the spectrum, to devices offering home automation and enabling utility control of appliances at the other. Following text from Delta ee (useful definition/breakdown): ‘HEMs mean different things to different stakeholders, and are being deployed around the world for a range of different purposes. Delta defines HEMs as in-home tools which offer one or more of the following functionalities: Inform – a one-way flow of information, displaying energy usage data to end users. Automate – the two-way flow of information between a „hub‟ and appliances, enabling customers to „set and forget‟ the operation of household appliances and microgeneration. Control – as above, plus enables third party control of household appliances via pricing or other remote signals. Link to next slide….Of these new smart technologies and appliances coming to the market in the next couple of years…….

Smart Metering Roll Out OCTES Workshop 31st October 2012 Smart Metering Roll Out Under UK smart meter roll-out gas and electricity meters will be offered to every home: In England, Wales and Scotland by 2019 All homes in Northern Ireland by 2020 Nearly 1m smart meters already distributed No-one will be forced to have a smart meter Provision of an in-home display for all households

Customer Benefits of Smart Metering OCTES Workshop 31st October 2012 Customer Benefits of Smart Metering Ofgem found typical 3% saving is achieved from installing smart metering in homes, but this depends on providing appropriate advice and support interventions, alongside the new meter. Lower than the typical reported saving achieved in other countries – around 8-10% Talk about oil meters too

Smart Metering Advice Project - Objectives OCTES Workshop 31st October 2012 Smart Metering Advice Project - Objectives Develop the tools and personalised advice provided by the Energy Saving Trust, specifically: Enhance our web tool to display smart meter data (and provide advice based on this) Tailor and improve accuracy of advice (using smart meter data) Explore extent to which these enhanced energy saving advice services, linked to smart meter data, can deliver local and national CO2 and energy saving, and protect vulnerable people from fuel poverty. The Energy Saving Trust has worked as the national home energy advice service for Scotland since 1991 Use smart meter data to: Tailor and improve accuracy of advice Deliver energy related behaviour change  Explore the extent to which these enhanced energy saving advice services, linked to smart meter data, can deliver local and national carbon and energy saving, and protect vulnerable people from fuel poverty. Project to be completed by March 2013

Smart Metering Advice Project - Activities OCTES Workshop 31st October 2012 Smart Metering Advice Project - Activities Enhancement of web-tool, developing new interface and making use of smart meter data for a SAP based tool Recruitment of homeowners and piloting the tool Training ESSac advisors Provision of proactive and reactive advice Evaluation Aim is to focus on ensuring that smart metering can really deliver

The EST Home Energy Check Presentation to Everest 31st October 2012 The EST Home Energy Check Every home is different The Home Energy Check calculates energy saving based on your windows, doors, roof, heating system What’s right for my home? Allows householders to see the best improvement measures for them and their budget How will I really benefit? Quantify and show clearly the improvements in CO2 emissions, EPC rating, likely energy bill

Key Features – a focus on energy saving improvements Presentation to Everest 31st October 2012 Key Features – a focus on energy saving improvements Smart meter data feed Linking with long established EST advice delivery, particularly in - person advice Focusing on actions householders can take to improve home EE, and what those actions will mean for householders’ bills Behavioural advice Not appliance by appliance, or highly granular energy use reporting tool Existing Home Energy Check engine (not developed through OCTES) Elements in blue have been developed through OCTES project telephone advice using smart data New interfaces

SAUSAGES EST’s Home Energy Advice Tool: Background SAP rating Energy demand/ energy cost Detailed property dimensions & performance values for heating, lighting, building elements - walls, windows & doors

RdSAP EST’s Home Energy Advice Tool: Background EPC Software Recommended EE improvements in standard order using standard costs and performance values Look up list of inferences for different property characteristics Look up list of recommended measures, costs and savings

SAUSAGES Dynamic Engine EST’s Home Energy Advice Tool: Background Recommended EE improvements based on customer preference and goals Inference engine dynamically calculating SAP inputs around levels of information available about the home Recommendations engine feeding data back and forth to SAP engine to identify best solutions for customer

Key limitations of SAP based advice tools OCTES Workshop 31st October 2012 Key limitations of SAP based advice tools Occupancy and behaviour based on standard assumptions No way to reflect real energy use SMAP enhancement adjusts core SAP inputs to reflect real people and real patterns of energy use

OCTES Workshop 31st October 2012 The future? Improve the tool and advice service based on project’s evaluation: Feedback from households Analysis of the data Obvious additions/improvements Renewables Water Continued provision of associated advice Link to next slide ….see tools like this one – whose development has been funded as part of the OCTES project - as part of the future…. Text from Philip’s recent New Statesman article: Using the latest energy saving technologies and home energy management systems needs to be combined with consumers behaving more sustainably in the home whilst being provided with ongoing advice. Without the right advice, new technology will not have the desired impact on energy use and consumption. Pound-for-pound using less energy is significantly cheaper than upgrading the grid to deal with increased energy demand. The challenge remains encouraging and empowering people to behave more sustainably in the home. This can be done through the latest smart technologies and appliances, but there is only so much this will achieve. The key is creating the right balance between developing new technologies and consumers being more energy efficient in the home
