What is Powervault? For personal use only: FIRSTNAME LASTNAME (email address)

What is Powervault? A fully-integrated domestic electricity storage device. Giving homeowners a brand new opportunity to store their own self-generated renewable electricity, or cheap electricity from the grid. Enabling efficiencies that provide value and economic benefit to both homeowners and grid operators. powering the smart home

Lead Acid AGM, Lead Acid Tubular Gel, or Lithium-ion batteries. Battery capacities range from 2 to 6 k. Wh usable capacity of energy storage. Connected on the AC side of the house, so the installation is straightforward, and Powervault is universally compatible with all solar PV panels. powering the smart home

The Objective “To determine the potential benefits of home electricity storage of solar PV generated electricity for social housing tenants in fuel poverty” For personal use only: FIRSTNAME LASTNAME (email address)

Study Design • Battery Cohort (22) • 17 Bungalows in Macclesfield (Peaks and Plains) with elderly/vulnerable residents meeting Fuel Poverty criteria • 5 Semi-detached houses in Knutsford (Longridge; Great Places) with low income residents meeting Fuel Poverty criteria • Control Group - No Battery (4) • 4 Bungalows in Macclesfield with residents not in Fuel Poverty • All properties in study have pre-installed solar arrays (3 KW) • Utility usage patterns monitored via regular logging of meter readings, tracking of utility bills and via data collected by Powervault • Study to run Oct 2016 – March 2017, and has been extended to Sept 2017 For personal use only: FIRSTNAME LASTNAME (email address)

The Battery • NOMINAL CAPACITY • 6. 6 k. Wh • USEABLE CAPACITY • 3 k. Wh For personal use only: FIRSTNAME LASTNAME (email address)

How it works The battery enables “time shifting” of use of locally generated power • The battery detects when power generation exceeds demand diverts excess power to charge the battery • When the battery detects import from the grid it switches the battery to discharge to meet the demand • Lower grid demand equals lower bills • No impact on Fi. T payments • Best result should be achieved through resident awareness of battery status For personal use only: FIRSTNAME LASTNAME (email address)

One Resident’s View “I have a pre-payment meter. Before the battery was installed I was using almost a pound a day on electricity. It’s been in for three days now and I’m still on the same pound. I can use the money I’m saving to pay for the gas. ” For personal use only: FIRSTNAME LASTNAME (email address)

Over the next year we will have the technology to create a 15% IRR for our customers o The key features that will deliver this market beating ROI include: o Recycled and lower cost batteries – reduce upfront cost by 30% TIMING FEATURES Now § Solar PV arbitrage § Time of use arbitrage o Frequency Response control – increase revenue by up to £ 380 pa § Smart tariff control § Emergency plug socket o A larger (3 k. W) inverter, enabling the Frequency Response income stream that underpins the availability of third party finance for the mass roll out to homes By 2018 § Low cost / recycled batteries o Relationships with electricity suppliers to access new smart tariffs o Powervault has built up considerable knowhow in its product and control system design which results from more than two years of field operation. It also has patents pending on “plug and play” features which can further simplify installation and reduce costs.
