Deor Ms. Noriyuki,
The City of Boise ("City") submits the following comments on lnlermountoin Gos's
opplicotion for prudency determinotion for 2019 energy efficiency expenses. For o new
residentiol efficiency progrom, lntermountoin Gos's yeor two implementotion ond
subsequent evoluotion provides o net benefit to oll lntermountoin Gos customers ond o
foundotion for increosed cuslomer porticipotion in efflciency progroms going forword.
The City recommends the Commission find lntermountoin Gos's 2019 efficiency
spending prudent.
While octuoltherms soved were lower thon estimoted by lntermountoin Gos, the
389,3,l3 therms sovings ochieved exceeded the compony's plonning ond is on increose
ftom the first yeor of the progrom. As the progrqm motures, the City supports
incorporoting octuol energy efficiency progrom performonce into the lntegroted
Resources Plon to toke odvontoge of ovoided costs qnd resource needs more fully.
The supplementolopplicotion presented by lntermountoin Gos includes the complete
EM&V study by the 3rd porty evoluotor. The proposed chonges to the residentiolenergy
efficiency progrom generolly follow the progrom evoluotion recommendotions ond
onolysis of sovings reolizotion by meosure. The City osks the Commission to outhorize the
following proposed updotes to the Residentiol Energy Efficiency progrom without
modificotion: the retirement of the 70%tteploce insert rebote due to low utilizotion ond
limited sovings potentiol, the oddition of o Smort Thermostot rebote, the oddition of o
second-tier tonkless woter heoter rebote, on increosed rebote for the Tier I Tonkless
Woter Heoter, increosed rebotes for Storoge Woter Heoters, the oddition of o Boiler
incentive, ond clorificotion of the Combinotion Rodiont System requirements.
Bosed on lntermountoin Gos's EM&V study (Exhibit 8 poge 3 of 76), the Whole Home
rebote progrom con support higher incentives ond mointoin cost-effectiveness. The
Cily encouroges the Commission to direct lntermountoin Gos to odopt the higher

incentive levels for both tiers of the Whole Home rebote progrom ($],000 for Tier I ond
$800 for Tier ll) to encouroge moximum possible porticipotion in oddition to the reduced
boniers proposed in the compony's filing.
The City requests thot the Commission opprove lntermountoin Gos' Residentiol Energy
Efficiency Rebote progrom toriff ond efficiency progrom design with the inclusion of the
higher Whole Home rebote incentives.
The EM&V study olso identifies the conditions in the Whole Home progrom leoding to
the most significont sovings outcomes (Exhibit 8 poge 3 of 761: Air Seoling ot or below 3
ACH of 50 Po, Ceiling insulotion of or obove R49, Ducts, ond oir hondler locoted inside
conditioned spoce ond Furnoce Efficiency of or obove 977o AFUE. The existing building
stock in lntermountoin Gos's service oreo is likely less efficient thon the 20l8lECC
reference home used os the boseline in the EM&V. With the demonstroted strong
interest in existing lntermountoin Gos efficiency progroms ond the number of residentiol
remodeling projects, there is on opportunity to expond the sovings goined in new home
construction to residentiol retrofits. The City proposes lntermountoin Gos's EESC
evoluote the feosibility of implementing o residentiolretrofit progrom beyond the
cunent opplionce incentives offerings bosed on the Whole Home in future progrom
yeors.
