Decarbonizing New York State’s Homes
Agenda
1. Review subsidy design
2. Step through 3 sample households
3. High level outcome results
4. Review total program costs
5. Questions about mandate
subsidy design

UPgrade Scenarios
- Already have heat pump
- Heat pump alone lowers bills
- Heat pump + weatherization lowers bills
- Heat pump + weatherization + repairs lowers bills
- Insufficient subsidies
- Heat pump increases bills

yearly cost to state
For those who meet a 7 year payback


If there is a mandate,
costs increase ~ $660 M a year
$16.5 B over 25 years
Who is in the insufficient subsidy group?

HOw far away are they?

New technology
55 % of Multifamily households would receive a window unit heat pump
Saving an average of $2,230 per household upgrade
Final questions
- Subsidies include baseline boiler cost?
- Mandate for those with insufficient subsidy?
- Mandate if bills go up?
- Maximum subsidy $ amount?
Who will electrify

Subsidized heat pumps can be paid back with energy savings in < 7 years
Will choose weatherization if
- Heat pumps alone increase bills
- Subsidy costs are lower (smaller heat pump)
Will choose if bills would increase without repairs and weatherization
Annual savings are not even to payback costs in < 7 years
*increasing subsidy amount can shrink this group
Heat pumps increase energy bill
Should this group be exempt from mandate?
