2 Agenda Gateway Hub Some Context Future of Domestic Solar Solar for Schools

3 The Gateway Hub at Steyning HOW DO WE PROVIDE POWER AND LIGHTING AT THE HUB WITH NO GRID CONNECTION

4

5 What we installed

6 Off grid works No need for a grid connection, electricity contract, ground works Internal lighting in the Hut Secure and Safe Environment using sensor controlled low wattage LED lighting that has no impact on the neighbours Power for charging tools and other equipment Designed to work all year round

7 Future of Domestic Solar HOW THE END OF THE FEED-IN TARIFF WILL PROMOTE GREATER IMPACT ON ENERGY SAVING

8 Some Context WHAT IS HAPPENING IN THE ENERGY MARKETS AND WHAT IS THE OUTLOOK FOR THE NEXT 5 YEARS

9 UK Power Wholesale Price

10 Brexit

11 Obsolete Infrastructure 1Bn investment per annum on grid Barely supporting the current demand Has it got the capacity to support more Solar PV or EV Car Storage?

12 Hinckley Point Cost - 18bn (Est and not including the over spend) 18Bn would pay for Solar PV and Battery Storage on 17,000,000 homes (68% of all homes in UK) We are plugging in large generation stations to an obsolete grid network - 800m to connect

13 Prices are only going to rise Electricity prices are forecast to rise from 17p/kWh in 2018 to 20.5p/kWh in 2020, a 20.5% rise Gas prices are forecast to rise from 4.0p/kWh in 2016 to 6.0p/kWh in 2020, a 50% rise DECC: Updated energy and emissions projections: 2015 Annex M

14 UK lacking direction End of the Feed-in Tariff announced for new entrants from April 2019

15 The end of the Feed-in Tariff should be celebrated, not feared. We can now start to design Solar PV as part of sustainable smart home environment to save CO2 and not just a standalone product that just generates government subsidy income Mark Stevenson (2015).

16 FITs Impact on Domestic Solar Solar PV installations will reduce in the short term but will continue with a mix of other technologies Financial Perspective: Electricity prices were at approx. 7-9p p/kwh when the FITs rate was 40p p/kwh Equipment prices have bottomed out at 50% cheaper than 2008 At 20p p/kwh there is no need for FITs to achieve a 5 Year ROI on a 25 year lifecycle Energy Saving Perspective Better integrated technologies Much more efficient use of generation via battery storage

17 Battery Storage, Smarter Homes, Better Efficiency THE FUTURE OF SOLAR PV IS BASED ON INTEGRATING MULTIPLE TECHNOLOGIES TO MAXIMISE SAVINGS

18 Household Solar PV halfway there

19 Export as little as possible Most 4KWp domestic systems without battery storage on average use between 40%-70% of their generation internally. All domestic systems in the UK registered for the Feed-in tariff get what is called deemed export currently at 5.24p Deemed Export assumes that the system exports 50% to the grid and will pay the owner 50% of generation. If your system generated 4,000kWhs a year then you would receive an export payment of In order to maximise the impact of Solar PV on your energy bills you must export as little as possible. You get a guaranteed export rate as above but are losing up to 300 a year by not utilising the full generation. The best ways to maximises the peak day time usage includes battery storage, using appliances such as washing machines / dishwashers / tumble dryers, storage heaters etc on during this period.

20 Combining Efficiency & Generation Integrating Technologies to maximise savings Saving up to 95% of Energy Costs for a House and providing a comfortable living environment

21 Solar PV and Battery Storage

22 Battery Storage

23 Pros and Cons of Battery Storage Pros: Maximise PV usage Reduce night time energy usage Grid Independence Integrates into Smart Home Cons: Still an expensive purchase with longer paybacks 10 Year life cycle of batteries Need to be ensure that your PV generates enough to charge batteries all year.

24 Energy Saving for Schools

25 Our Energy Management Approach

26 Holistic Approach LED & Solar Instant Savings all year Improving Teaching & Learning Environments Hassle free installation Long term warranties Education and environmental benefits

27 Impact of getting it right

28 Social Enterprise Funding School specific funding backed by Santander, DLA Piper, KPMG and Baker Tilly Bright Spark are preferred installation and O&M partners No capital cost and generates net savings in year 1 Schools must apply for the fund and be able to demonstrate that savings are invested into furthering the educational outcomes of disadvantaged Children.
