HeatStreets

HeatStreets is a street by street approach to alleviate fuel poverty in private sector homes by targeting the Local Authority and Powergen funding at specific households

HeatStreets has been developed over 4 years in Derwentside and has subsequently been rolled out over the whole of Sunderland City

HeatStreets has 3 main objectives:1) To target a LA budget towards measures in households

defined by the LA as priority

2) To maximise the opportunities for energy efficiency improvement in the targeted area

3) To deliver maximum financial leverage from the LA funding by combining with Powergen, local residents and Warmfront

For every £1 contributed by the local council, £3 comes from other sources


Customer Proposition

Grants are targeted at 3 specific levels to facilitate the installation of cavity wall and loft insulation, draught proofing, hw cylinder jackets etc

A) Grant A- for every priority household –(those on a means tested benefit or in fuel poverty)

B) Grant B- for households ‘over 60’ not on benefit

C) Grant C- for households ‘under 60’ not on benefit

The able to pay rates are comparable with Powergen’s national scheme

Household Criteria

Funding: Example

Grant LA Powergen Customer Total Homes

A £200k £200k nil £400k 1200

B £50k £50k £100k £200k 600

C nil £150k £300k £450k 1500

W Front nil nil nil £250k 700

Total £250k £400k £300k £1.35m 4000

Assuming a split of fuel rich (C grants), Warm Front and Council funded work (grants A & B) as above the following can be expected

Based on Sunderland HeatStreets Scheme

This enables the LA to target specific customer needs in the local community


Targeted Funding

There is no ‘fixed’ investment required from the LA, a project will be formulated around available budgets

A LA budget of £250k would improve 4000 homes and help to remove 1900 vulnerable households from Fuel Poverty

This approach can be used Borough wide or just to target particular estates

Grant penetration with this method means measures are required at 1 in 4 i.e. a 25% take-up of measures

Each household could save up to £240 per year on Heating

costs (based on CW and LI installed in an uninsulated 3 bed Semi-Detached house


Pocket Affordable Warmth Survey

Identifies the "fuel poor" after a five minute doorstep assessment

Pocket survey provides:

FridgeSavers

National scheme to offer A rated Fridges and Fridge freezers to customers on benefit who own an old inefficient fridge

In partnership with Currys


Powergen HeatPlant

Ground Source Heat Pump designed for the social housing sector

Also a possible solution for off gas network fuel poor.


What is a ground source Heat Pump

A heat pump collects and concentrates solar energy stored naturally in the ground

Heat Pumps can operate over a variety of mediums, air to air, air to water and water to water

The pump distributes this heat through the domestic heating and hot water system in the same way as a conventional boiler

The heating is “low grade” i.e operates at around 50oC


How HeatPlant works


The benefits of HeatPlant

Environmental

Up to 50% lower CO2 emissions

100% sustainable technology with 20 year lifetime for the HeatPlant and 50 years for the ground loop

Economic Provides full space and water heating for around 75%

of the cost of conventional gas boiler

No need for annual Gas safety checks

No need for additional immersion heating

1kWh of electricity can extract over 3kWh of renewable energy


HeatPlant Installation






Powergen HeatPlant unit

The unit is 450mm wide, 550 deep and 800mm high and would fit under the surface in a kitchen


HeatPlant Comparison

(SAP 2003)

Ground source heat pump £215 1.6 tonnes

Natural gas boiler (condensing) £300 2.9 tonnes

Natural gas boiler (non-condensing) £345 3.3 tonnes

LPG (bulk) (non-c.) £500 4.3 tonnes

LPG (bottle) (non-c.) £670 4.3 tonnes

Oil (35sec) (non-c.) £300 4.4 tonnes

Electricity (storage + panels) £510 6.5 tonnes

House coal (closed stove + back boiler) £380 6.6 tonnes

Smokeless solid (closed stove + back b.) £515 7.5 tonnes

GSHP@ Braddock House £187 1.3 tonnes


HeatPlant Progress to date

92 installations to date 62 over 4 sites in Nottinghamshire

6 on a site in Worchester

24 on one site in Cornwall – 16 of which were retrofit

We have raised the profile of a technology that is installed in tens of thousands in Europe and hundreds of thousands in the USA

Gordon Brown reduced VAT on GSHP in the last budget


What is Micro CHP?

A direct replacement for the boiler in a central heating system

It burns gas to produce heat just like a boiler, but...

At the same time it generates FREE electricity

Some of the electricity you use in the home

Any surplus is purchased by Powergen

What are the benefits of mCHP?

Environmental benefits Reduces Carbon emissions

Social benefits Helps to eliminate fuel poverty particularly helpful

in the solid walled properties where an efficient heat source is critical

Economic benefits Reduces fuel bills by around 20%

The Challenge of EEC II

EEC II – 2005 – 2008

Market Transformation


EEC II – 2005 – 2008

EEC II like EEC I is still primarily a Carbon saving programme

The Energy White paper called for around 1 MtC from the new EEC


Market Transformation

Cavity Wall Insulation will be the single most important measure in EEC II

The energy white paper referred to 4.5 million cavity wall installations between 2005 and 2010 which equals 750,000 per year

What do you think is the current rate of installation as measured by the insulation industry?

EEC II wouldRepresent 1.74 million CWI


The EEC II Challenge

This represents a 50% year on year growth in the insulation industry during EEC II

And if we fail Ofgem will have the powers to fine Suppliers for not delivering their targets

We are all familiar in our roles at work with having to deliver targets in our performance driven economy

S.M.A.R.T Specific Measureable Achievable Realistic Time period


Is EEC II at SMART target?

Is EEC II Achievable?

Is EEC II Realistic?

Few of us I believe would be happy to accept a target where the ability to deliver is outside our control
