Scope  My role as development officer  Hjaltland Housing association  The 6 home trial and impact  Benefits of DDSM  Project learning and wider roll out

Development officer: my role  Assist in coordinating the project  Liaise with tenants  Develop education for users  Monitor, progress and deal with tenant concerns  Publicise and promote the project

 Over 620 houses  Real life setting for trial  A “friendly face” Hjaltland Housing Association Ltd.

Tenant feedback “Definitely a positive experience” “Now we’ve got a greater degree of input in how we use the heating to meet our needs” “We’ve got a better heating system out of it, more hot water and it’s been interesting” “There are more options for heating the house and it’s just very user friendly” “I’d definitely recommend it to a friend”

Trial heaters: user problems  Tenant’s felt settings too complicated  Didn’t encourage adapting to suit their needs  ‘Clunky’ design

New design: Quantum heater  Simplified design  Settings “fool proof”  More streamlined outer casing

Impact of system  Enhanced controllability  Increased hot water availability  Economical form of heating  Tenancy changes presented challenges

DDSM Trial: Benefits for HHA  Value for money heating + greater comfort for tenant  Low installation costs  System helps towards SAP ratings - “future proof” homes  Raises profile of association as forward thinking and “green”

Energy Storage Portfolio Management  Real requirement to understand portfolio risk management in storage and DSM  Stakeholder motivations diversity  Stakeholder Funding Source / Sector diversity  Technology Risk Diversity  Policy impact diversity  Hedged against new technologies

What next: Learning and managing portfolio risk  Local authority withdrawn from NINES project  234 social houses still to benefit  Potential for private home owners to participate  Challenges: engaging customers at the right level
