4 Electric Storage Heaters: Dead or Alive? Introduced in the 70s and 80s to use surplus night-time nuclear generation not as a way of optimising the quality of heat for tenants How can you take existing electric storage heaters and turn them into an advanced 21st century heating system at no cost to the tenant or the landlord?.....and deliver better heat at a better price, and as part of a plan to “keep the lights on”!

5 The Electric Storage Heating market In GB 26m households incl 2.2m with electric heating (8.1%) In Scotland 2.4m incl 318k with electric heating (13.4%) 4m in GB are in social housing – many are managed as ‘heat with rent’ where the landlord pays for the heat energy Social housing loads are concentrated in cities, often in tower blocks, with a high % electric heating in cities e.g. Dundee 22%, Glasgow 17% Other applications include sheltered housing and student accommodation Probably the most deferrable load in GB electricity usage?

6 Case Study CityWest Homes (Westminster City Council) 8 tower blocks Landlord-managed “Heat with Rent” service Local LPT signal on 415V replacing UKPN HPT signal on 11kV Receiver in each flat switches water and space heating Heating to / Water to Existing flat meters to be replaced with Community Half Hourly metering Low Power Transmitter Existing Wiring 6

8 Making it better for the tenant? What if..... we charged their heaters during the day and made their houses warmer at night? gave the supplier the ability to source energy when it’s cheap? gave the distribution network owner the ability to control loads in their area? gave the transmission operator the ability to switch on/off aggregated loads to help them balance the network? installed temperature monitoring at each storage heater to ensure that each room has sufficient heat?

9 Actual - With electric thermal storageEstimated - Without electric thermal storage Adds to peak Off-peak tariffs consume more than 20% of all UK electricity today UK's electricity safety 'cushion' is just 4% - half last year's figure Storage Heating: Impact on UK Energy Supply 9 7 VCharge – Proven aggregation experience in USA

10 Use historical usage data, weather and electricity price forecasts, and grid needs to plan optimal charging of storage heaters Gives transmission and distribution operators, and energy suppliers the ability to control a large aggregated load asset – Smarter Energy Procurement – Frequency regulation – Avoid wind curtailment Unlike traditional Demand Response, there is no impact on the customer experience The Power of Mathematics

11 No.1 goal – Keep people warm.....but also: - Optimise procurement - Manage demand/capacity

12 Something for everyone?

13 Summary Landlord-managed Heat-with-Rent properties (tower blocks, sheltered housing, student accommodation) Convert Hot Bricks to Grid Batteries Better quality heat for all residents Lower prices for all residents Use renewable energy when it’s available (wind/solar) Contribution to “keeping the lights on”
