In this trial this will vary at different times of the day. 1 Welcome Thank you for participating in the SWELL trial. This booklet should give you information about the trial and the Hestia Home Energy Management system. We will update the copy on if new features are added. 2 Overview of Energy Local Energy Local is a new means by which a community can pool locally their own generation. The owners of the generation receive a better income from any power that they don t use (i.e. export) and the local users receive a better price if they use power which has been generated locally. The community is also offered different power from their supplier at different prices, depending on the time of day. As well as reducing the cost of power, more income is retained within the community. This makes renewable power more viable. To help a community match their energy use to local generation and cheaper prices at different times of day, Energy Local is working with partners to develop a home energy management system that works on a community scale. More information at 3 The SWELL Trial The SWELL trial is to test out the Energy Local model in Shrivenham, Watchfield and Longcot. The trial is being co-funded by InnovateUK. As one of the 50 participants you are testing the idea to see how much you can save from shifting when you use power and matching local generation (in this case solar photovoltaic - PV - generation). You are also testing a prototype of the energy management system to help schedule loads and understand your energy use. There are 16 participants with solar panels. It is their generation that we will share within the group. The Environmental Change Institute at Oxford University will be carrying out surveys during the project to find out how you are getting on and to learn about your motivations.

4 p/kwh SWELL WELCOME PACK 3.1 Tariffs For the SWELL trial we are not changing your energy bill. However, we are giving you a dummy tariff with different prices at different times of day. If you move when you use electricity to when the price is cheap, we will give you the equivalent of the savings you would make in Cooperative Shopping vouchers. The prices at different times of day are shown below in the table and on the graph. Remember local solar is always the cheapest at 6.5p/kWh. Time Price p/kwh 00:00 to 06:00 (Overnight/early morning) :00 to 11:00 (Morning peak) :00 to 17:00 (Daytime) :00 to 21:00 (Early evening) :00 to 23:00 (Late evening) :00 to 23:59 (Night) Price for solar when available Prices During the Day 23:00 22:00 21:00 20:00 19:00 18:00 17:00 16:00 15:00 14:00 13:00 12:00 11:00 10:00 09:00 08:00 07:00 06:00 05:00 04:00 03:00 02:00 01:00 00:00 time So that everyone is treated the same we are comparing you savings against the cost of power if you were on a standard tariff from SSE. This is 13.37p/kWh. For those who are on Economy 7, the two rates are 16.02/kWh and 7.35p/kWh. You may have a lower tariff but we need to have a benchmark. If you export generation that is used within the CESCo you will receive 6.5p/kWh. If you use power generated in the CESCo it will cost you 6.5p/kWh. Page 4 v1.05 Energy Local Ltd 2015

5 3.2 How you will receive your savings We will calculate your savings once a quarter during the 12 months of the trial. We will send you Cooperative Shopping Vouchers with a description of how you saved power. You will also receive a 10 voucher once the equipment has been installed. 3.3 Events during the Trial We will be organising events during the trial for you to discuss how you are getting on. We also plan a celebration nearer the end. 3.4 Surveys A researcher from the Oxford University Environmental Change Institute will be carrying out surveys at the beginning, middle and end of the project. The first survey will take place either over the phone or in your home occur between 1-3 weeks after installation will take around 20 minutes aim to find out how you use energy in your home, your motivations for taking part in the project, the degree of control you feel you have over your energy consumption and how much of your electricity use you might be able to shift to different times if necessary Subsequent surveys will take place in spring 2016 (either online or postal) take place towards the end of the trial (either phone or in home) be concerned with how the trial is working out from your point of view take between minutes 3.5 How the control works Each day around midnight your control box will receive two pieces of information from a central server to help you use power during the next day. These two pieces of information are: A table of the price of power at different times of day offered by the supplier (for this first trial this won t change from day to day) A signal that shows good or bad times to use power. As well as the price of power from a supplier, this uses a weather forecast to estimate the amount of local generation (e.g. from solar panels). For example, the best time to use power will be in the middle of the day if it is a sunny day and there are solar panels. The signal will be used to influence the time when appliances under automatic control will operate, according to your preferences: If you have storage heaters and electric water heating, the control box will find the best time to put heat into the storage heaters and heat up the water. You will be able to enter how warm you need the home. You will be shown how much hot water you have available and you will be able to boost this, if necessary. The system will always ensure there is some hot water available. V1.05 Energy Local Ltd 2015 Page 5

6 If you have a battery installed, this will charge and discharge in the best way to save money. The remotely controlled plug will switch on an appliance. You will be able to enter a period of the day when you would like the appliance to run. The control box will use the signal to select the best time of day to switch it on within that period Immersun Some participants with PV have Immersun devices use the excess generation to heat water. With a few exceptions, we have asked you to switch these off during the trial. You will receive more for this power in Coop Vouchers than the value you would save from reduced use of gas. 3.6 Information on the cost of power and amount of generation available. On your display there will be a page that shows the cost of power at different times of day. This is calculated daily and takes into account the amount of solar PV generation available within the community each day. This display will be the same for all users irrespective of whether they have PV on their roof or Maslow battery units, or neither of these. We will would like your comments to help us make the display as easy to understand as possible. Predicting the amount of generation available on a local scale is difficult. We won t perfect this first time! Where possible it may be worth looking out of the window to double check. We will work to improve the prediction of generation during the trial. 4 The different components 4.1 Hestia Hub Control box This is the brains of the system in your home. It receives information from the central server and from your display interface and provides local control for some appliances in your home. 4.2 Display Interface This is where you can see how much power you have used and when. It will show you the tariffs and forecast the amount of local generation available. You can use it to manage your smart plug, and your storage heaters and water heating if you have them and they are part of the trial. We will be grateful for feedback so we can improve this interface. 4.3 Broadband communication The system uses your broadband to communicate with a central server. It also uses it to communicate with your display. It is particularly important that the broadband is on at least once a day. Ideally from 23:30 to midnight or early in the morning to pick up the forecast for the next day. If your broadband is not on or broadband fails, it will use the information from the day before. 4.4 Setting up your system When the electrician installs your Hub, he will ask you to enter your broadband password, the system should then connect automatically. If there seems to be a problem, unplug the Hub, plug it back in again. It should reconnect automatically. Page 6 v1.05 Energy Local Ltd 2015

7 4.4.1 To see your display on a laptop, tablet or smartphone To access your display, if you're using Windows, Apple OS X, Linux or an iphone: Open a web browser and enter into the address bar. We will install Apple software Bonjour Print Services on your Windows computer or laptop to enable them to communicate with your hub. If you're using an Android device (e.g. most smartphones that aren t made by Apple), you must download an app. Open a web browser and enter into the address bar. Click the downloaded file to install the app. Once installed, you can use this to access your display (as long as you are connected to your home broadband network) Note: you may need to configure your Android to allow app installations from.apk files. To do this, on your android phone go to: > Settings > Security - Device Administration Click to allow "unknown sources". Then you can install the file you just downloaded Setting users and passwords The admin name and password is printed on the Hestia box label. You can add and remove users for your display. Go to Admin and the Users tab. Give each User a name and password and press add. To remove a user press remove. V1.05 Energy Local Ltd 2015 Page 7

8 If someone forgets their password, you can always log in using the name and password printed on the Hub label Notifications You can enter an address to receive automatic notifications. For example if your broadband fails. Go to the Notification Tab and enter an e mail address. Tick Enable Notifications and press update. You can turn off notifications by unclicking the Enable Notifications and pressing Update 4.5 Smart plugs These can be used to control appliances from the plug socket. Be careful digital washing machines and dishwashers may lose their settings if turned off at the wall. If this is the case you cannot schedule them using the smart plugs. Many modern appliances have a delay start option so you can manually set them to start when the power is cheapest. We would not suggest you connect any critical loads to the smart plug, just in case something doesn t work quite right. Page 8 v1.05 Energy Local Ltd 2015

9 4.6 How to control smart plugs On the display interface go to the smart plug page. Smart plugs are labelled A, B, C, etc. We will supply you with one plug but you can buy more at: Firstly, you need to set up your smart plug. Select an appliance name and a cycle length. Make sure you always leave more time than you need for a task to run, to make sure it has finished before the plug is switched off. Once you have completed the settings page, two more tabs will appear Timeline and New Tasks. Select the New Task tab. Fill in when the cycle needs to be completed and press add to schedule. You may schedule repeated tasks here too. V1.05 Energy Local Ltd 2015 Page 9

10 On the timeline you can see what tasks have run and what are scheduled. You can cancel schedules here too. Please note Avoid putting two smart plugs in adjacent/close sockets or in a socket near to the Hestia Hub the communications can get confused. The smart plugs may occasionally stop responding if they lose their pairing information. If this occurs, press the button on the front of the smart plug until it flashes, then send a test on/off from the hub the orange button at the bottom of the settings screen. Page 10 v1.05 Energy Local Ltd 2015

11 4.7 Storage heater and Hot Water Control If you have storage heaters or electric water heating and they are part of the trial, the control will put enough energy into your storage heater to ensure you feel comfy in your home. It will keep hot water ready for you to use. You may need to boost the water heater it if you need extra hot water How to control electric hot water The system will provide a regular amount of hot water available and learn your habits. You can see how much hot water is available by water tank graphic, and other indicators on this page. If you find at any point you find you need more water heated, please press the Need more hot water? button. V1.05 Energy Local Ltd 2015 Page 11

12 4.7.2 How to control electric storage heaters The control will automatically predict and deliver enough energy into your storage heaters, depending on your preferences, the weather forecast, and the type of house you have. You can indicate how warm you like to feel by selecting a heating profile. You can select which heaters are charged by switching them on during the night individually using their main switch and select which heaters to use during the day by switching them on individually. You can use the boost direct heater if necessary as usual (but we hope you won t need to do this). Please let us know if you need to use the boost heater more than normal. Page 12 v1.05 Energy Local Ltd 2015

13 4.7.3 Holiday Mode If you want to turn off your heating whilst on holiday, go to Admin and the Occupancy tab. Add the date you are leaving and the date you are returning. Press submit. You heating with then be ready for you when you return. Press cancel if you want to remove the holiday mode. 4.8 Electrical storage We are trialling 10 storage units (batteries). They will charge at the cheapest time of day so you can use this power when it is more expensive to buy from the supplier. The batteries will provide power to your home electricity supply so that you can use the power for anything. The battery will charge and discharge automatically. V1.05 Energy Local Ltd 2015 Page 13

14 4.9 Changes to your broadband password or loss of connection to WiFi If your hub is connected to your internet with WiFi: Check the list of local WiFi networks. If there is one with a name "HestiaHub_****", then that means your Hub has lost connection to your house internet. Connect to this WiFi network (there is no password required) and then type this address into your web browser: " ". Then follow the instructions on screen. If there is no WiFi network called "HestiaHub_****", turn your HestiaHub Control box off at the mains, and turn it back on, then wait for 5 minutes and try again. If you still have problems, please contact us (section 6) If your hub is connected to your internet by a cable: Check that both ends of the ethernet cable are plugged in, Wait 2 minutes and try to access hestia.local" webpage, or launch your Android app. If you still can't see your webpage or icon, turn your HestiaHub Control box, off at the mains, and turn it back on, then wait for 5 minutes and try again. If you still have problems, please contact us (section 6) Your Data On the display you will be able to see your power usage. We will also send you information about when you are using power when we send your vouchers. We can give you data about your energy use over a longer time scale if you request it.

17 8 Energy Use in the Home and Its Cost This section is aimed to give you some information about how much energy different appliances use and when we typically use them in the day. It then gives an idea of the difference in cost of running different appliances at times of cheap or expensive electricity. Power used by different appliances The power that is used by different appliances in a year for a typical household is shown in the bar chart below. The black bars show the consumption if they were bought in 2009 and the red bars if they were bought in You can see that some items are now much better designed so they use much less power. For example, a new chest freezer now uses about half the energy it did in Everyone s habits are different so how much they use different items will vary. However, you can see from the chart the items that tend to use a lot of power washing and keeping things cool. Other items will add up because you may have a lot of them. If you have a lot of lightbulbs or electronics, although each one does not use much power, in total the power they use will add up. When do we use different appliances and how much does it cost? Below is a graph of when we typically use different appliances during the day. Quite a lot of a household's energy use is unknown. This could be anything that plugs in e.g. vacuuming, ironing, hairdryers, toasters. Again, every house will be different. V1.05 Energy Local Ltd 2015 Page 17

18 Not surprisingly households do a lot of cooking in the evening and electric showers are used in the morning and evening. Under Energy Local, power will cost different amounts at different times of day. The next tables show the typical annual running costs for appliances if the power costs different amounts. Remember, power will be more expensive during the evening with an Energy Local tariff. These figures are for typical usage during a year, some people will use some appliances more. For example, if you more washing than average, your washing machine costs for the year will be higher. The first table shows typical costs over the year for: Lighting this is hard to schedule without a battery but the table shows the difference in cost when efficient lighting is used. Fridges and freezers - eventually these could be cooled during times of cheaper power. Wet appliances for laundry that you could schedule to run at times of cheaper power.

19 The second table shows typical costs over the year for: IT and electronics those with batteries can be charged during times of cheap power. Cooking and electronics you could change your routine to save money. 9 Energy Savings from Efficient White Goods We don t change our white goods very often. When we are standing in the show room, the savings from buying an efficient model may be hard to imagine but, over the years, the savings add up. Energy Efficiency ratings are from A+++ to C or D. Very old goods will have lower ratings than this scale. The fact that there are now new categories up to A+++ shows how much more efficient appliances can be nowadays. For most goods, no products are sold with a rating below B or C today. Note that keeping old appliances as spares could be a significant cost to you. Likewise accepting old appliances that have been passed on may be costly in the long run. Washing Machines The energy ratings are assessed for a typical use per year and per cycle are given below (costs are estimated assuming a rate of 14p/kWh. There is ~ 11/year saving between an A to A+++ rated machine and yet A+++ machines need not be more expensive to buy. Typical energy use and costs: Washing machine rating A +++ A ++ A + A B C D Max kwh/year Max cost/year [ ] Savings of A+++ [ ] Max kwh/cycle Max cost/cycle [ ] Games Consoles Power Supply Units ( ) Set Top DVD/VCR Desktops Laptops Monitors Electric Electric Microwave price /kwh Box ( ) 2 ( ) 3 ( ) ( ) ( ) ( ) Oven ( ) Hob ( ) ( ) Saving if power costs 0.06 instead of 0.14/kWh Savings from A+++ /cycle [ ] Different machines use different amounts of water which you may also want to compare the amount of water that machines use especially if you are on a water meter. V1.05 Energy Local Ltd 2015 Page 19

20 Dishwashers Dishwashers are rated according to a typical yearly usage. Dishwasher rating A+++ A++ A+ A B C D Max kwh/year Max cost/year Savings from a A+++ model Between an A rated and A+++ rated machine there is nearly 15/year saving. Whilst A+++ products are more expensive to buy there are A++ rated designs of the same price as A rated options. You can get 10 of the savings at no extra capital cost! Different machines use different amounts of water which you may also want to compare the amount of water that machines use especially if you are on a water meter. Fridges and Freezers It is difficult to compare one fridge to another or one freezer to another as they are all different shapes and sizes. The Energy Rating is calculated by comparing the energy use with the internal volume. Below are two examples. If your fridge or freezer is nearly empty, the door is not shut or you keep opening and shutting the door, it will use more power. There are few fridges and freezers that are A+++ rated and they tend to be more expensive. Nevertheless A+ rated fridges are similar in price to A -rated products and gain a 10/year saving. An A++ fridge saves 14 saving/per year compared to A, this is around 20/year for a fridge freezer. Fridge rating A+++ A++ A+ A B C Fridge kwh/year cost /year Saving to A+++ rating Fridge freezer A+++ A++ A+ A B C kwh/year cost /year difference in cost to A+++ rating For very old fridges and freezers, the running costs will be even higher than the figures shown for the C-rated appliances shown above. Total Savings So without additional capital expensive purchasing energy efficient white goods could save you 40/year in running costs. The savings will be greater if you are replacing older, poorly rated appliances. Page 20 v1.05 Energy Local Ltd 2015
