Housing data & peak load growth

Our resident Realtor Pat Phillips looked up the multiple listing services for the past four to five years and compared the reality with Idaho Power's Integrated Resource Plan projections:

IRP Projection/Actual building permits

2005 - 13140 / 15505

2006 - 11784 / 11730

2007 - 10701 / 5668

2008 - 10423 / 2374

2009 - 9675 / 54 (year to date)

Housing Sales per Intermountain MLS

Ada / Canyon / Payette / Malheur County

2005 - 13,209 /6,310 /475 /269

2006 - 11,101 /5,698 /439 / 293

2007 - 7,824 / 3,519 / 323 / 234

2008 - 5,871 / 2,377 / 211 / 154

2009 - ytd 709 / 262 / 27 /12

The steep drop off won't be going back up anytime soon.

Page 9 of IPCo's 2006 IRP Addendum states that "New housing growth and the associated increase in air conditioning load in southern Idaho is driving much of Idaho Power's peak load growth."

Peak load growth is one of Idaho Power's main rationales for placing its 500kV line through prime Malheur County farmland. It makes one wonder if southern Idahoans really prefer cool houses to growing food, since this is the way Idaho Power presents them to us.

The more cogent explanation is that IPCo wants the cheapest route for their regional B2H wheeling line, which might drop a few kwhs on us if we really need it.
