2012-2013 Billing Analysis Report - Indiana Weatherization Program

The Billing Analysis Report for homes Weatherized between April 1, 2012 and March 31, 2013 was completed at the end of March.  Here are a few highlights from the full report.

• 2,341 households were weatherized, serving 5,423 people.
• Average net natural gas savings of 264 therms (+/- 10), 22.6% (+/-.8%).
• The state average of 264 therms is the largest average measured since INCAA has been performing billing analysis for the entire state.
• Average gross electric savings for electrically heated homes of 1,571 kWh (+/-294).

The average net natural gas percent savings are shown in Figure 7 from the Billing Analysis report.  Ninety six percent of Indiana's Weatherization providers were able to meet IHCDA's net natural gas savings benchmark of 15 percent. 

Natural gas is approximately $1.00 per therm on average in Indiana.  So each therm saved is another dollar each weatherization household has to spend on something other than their gas bill.  Figure 8 from the report shows how many therms (and roughly dollars) each client saved on average.  $264 per year might not seem like much, but it is more than 1% of the average weatherization client's household income, assuming the household income is at the Federal Poverty threshold for a family of two.  The CAPs at the left hand side of the chart are worth noting.  They made an even bigger fiscal impact on their weatherization client's households.  And these energy savings are persistent for the lifetime of the retrofits, which means they will last for years to come, stretching the savings out into the future for the people living in that home.

The Billing Analysis process has begun again for the 2013-2014 DOE cycle.  So program managers can expect requests from me for additional data and fuel release forms in the near future.
