- Internet
Installed by Factory Authorized Dealers (Heating/Cooling Contractors)

4. Gas Usage and Electrical Savings (Beta Sites)
freewatt uses about the same amount of natural gas as the replaced system to make the same amount of heat
freewatt makes electricity as a bonus
beta units average 3400 kWh per year in the Boston area
beta units produce only 1.0 kWe versus 1.2 kWe for production model
projected 4000 kWh/year average with production model
The Heating System That Makes Electricity!

5. Reduced CO2 Emissions Electrical Generation Only
Based on average emissions for the New England electric grid
CO2 reduction could be 1to 4 or more tons per year depending on average emissions for the local grid
A utility could aggregate the emissions credits for thousands of installations

6. freewatt Systems Now On Sale Over 50 Production Model Systems Installed to Date
Hydronic freewatt systems also available

7. What Can freewatt Do?
Nearly double the Governor’s energy savings objective -28% immediately
Provide 80% of the energy and environmental benefit of residential solar electric power at 30% of the cost
Neutralize residential peak demand from grid
Produce significant amounts of on-site electric power at total costs comparable to typical residential utility rates
Provide automatic back-up power during grid outages
Widely deployable: Over 25 million candidate home sites
Siting challenges: None

8. Energy Savings with freewatt
The old way – gas fired central heat and grid power
Typical home heating fuel use about 100,000,000 Btu/yr (2500 ft. sq. home)
70,000,000 Btu heating delivered at 70% efficiency
Typical annual electricity consumption in NY’s single family homes is about 9,000 kWh
Net average delivered efficiency of grid is 30% with line losses, etc.
Total energy needed for electricity generation is about 9,000 kWh x 3412 Btu/kWh divided by 0.3 which equates to another 102,360,000 Btu/yr
So, total energy consumption is 200,000,000 Btu/Yr.
The new way - generate 5,000 kWh/yr by replacing old heating system at 70% efficiency with a freewatt Micro-CHP system
No actual increase in gas consumption due to increase in total efficiency to 90% (70% for heating with added 20% for electricity for a total of 90%)
5,000 kWhr is 55% of total electricity needed per year.
So now consuming 145,000,000 Btu/yr, i.e. 100,000,000 Btu/yr for heating and 45,000,000 Btu/yr for electricity.
55,000,000 Btu/yr saved.
Percentage reduction in total home energy use is 55/200 = 28%
Nearly double the Governor’s objective! (15 by 15)

13. What can AEE do to help fulfill the promise of Micro-CHP
What can AEE do to help fulfill the promise of Micro-CHP? Let your legislators and the PSC know that you support…
Net metering: keep it simple and low cost to interconnect and measure
Capacity Aggregation: allow thousands of homes to combine to provide dispatchable Megawatts
Incentive parity with “renewable” energy
Education
