Avista (the Compay) completed th two-year Energy Lo Manement pilot program on Decembe 31 st, 200. Dirct Load Contrl (DLe) devices were intaed in volunter household in portons of Sandpoint and Moscow.. Ido. A separate grup with those communties parcipate in an In-Horne-Display (lH) device study as par of ths pilot. The lH progr intent was to gai customer experience with "near-real ti" energy usage feeack equipment. Th purse of the pilot was to gain expeence with custoer actance, progr deign, oponal components and cot effectiveness. Th pilot was deigned to be scalle. Given the multiple tehnology and progr design options, the pilot progr as apved was to asist with determnig futue deloyment TIs projec ha provide experienc with spec technlogies that helpe to examne cot-effectiveness and customer accece of dema response equipment. Technology was tested for fuctonaty unque to Avista thereby ber defig system an hardwa reuiments, an assesing costsefits. Contrl tehnology in each DLC parcipant's home enaled th Company to inti culmt signals to electrc fuace, ai..conditionig unts, hea..pups and wat heate at ti of high peak demad. The Comany provided notcaon of thse events to parcipa twent-four hous prior to a "caled event." Custome wer alowed to opt-out at anyte. For parcipatig in the pilot. the DLC volunter houolds were provide eith a $10 pe month bil cret for up to five month for aplice that qualed for an event. or a state-of..th ar thostat. Volunters also were provided an oportty to ente a drwig to win a high- effciency washer and drer set. The ll grup receved a Blue Lie Poweros Monitor. As a product test, th piot provide sever fidigs: Eqpment compabilty on Avita's system (from th cusomer's mer) thugh to Avita's "back ofce" opeons wa tete and imved. A vita intiat te successfu event by either cyclig heati or ai-cnditioni units or shuttg off wat hete units for a peod of two to four hour. Th events took plac over a rage of morng, afoon and eveng pe demad ti slots. As a maret test. th pilot indicad a stg cusomer willgns to pacipa. Five pet of those eligjble volunre to join th progr. The overde (or cuome opt-out) ra averaed less th 2% over dug caled events. Parcipats showed wils to invest thei tie. work with the Company, re-arge thei day schedes. and reive either less hea less hot water or less ai-conditionig.

Five perent of the taget group responded either to parcipate or gai more inormtion. Shorty afr th diec maier was set, it be clear that the retig effort of commrcial customers woud be best peonned by another method as no commeral customer resnded to the dict maler. Ths suggeste that grter benefts would nee to be aparnt. to commercial customer, and alternative communicatons should be considered for their retment. Al respondts to the di maler were residential customer, which fied the ne for the availe DLC device. Strgies for futue dit maigs were leared frm ths pross.

Pilot Results & Evaluation The th result cagories which wi afec futu progr design: . Customer Accptce . Operaonal Components . Cost Effectiveness The results of these aspects are descbe in the following setions. Customer Accptace: The inti response to the DLe di maier of 3,100 was 155 cuer, or 5%. Of th th-one decided agait pacipation once they discovered the deta and na of the pilot progr. Th reason for not parcipatig was solely due to the custome not wantig anyone else to contrl thei apliances. Typcay in thse instce one household deon maker wante to parcipat, however, their par did not An additiona twenty-four customers who had signed up to parcipat opted-out of the progr before equipment could be intaed for reons unown. Ther wer twenty-seven custrs wantig to parcite in th pilot progr but ha too low of use or did not have qualg electc apliances to pacipate in the prgr. Once the progr was underay, no cutomer opd-out of th progr and ver few parcipan opted out of events. The largest opt-out ra ocun on Februar 2f1, 2009 from 5:00 AM to 8:00 AM exclusively with DLe, water-hear pacipats. Th househlds with severa members neeg a morng shower were impac and did not want to rege thei schedule to shower at a dieret tie. This reflec a four-percnt opt-ot ra fo that parcular event Otise, thughout th piot, no elecc heat Cutomers opted out, and only one customer chose to opt-out of two the ai..nditionig tets. Th pacu cuto was an at-home moth with sever chidren and did not want any discomfort Noticaons of the tet events listed abve wer given in seer ways. Mos chos to be notied bye-mal or telephone or both On customer preered being notified by fae (or Idaho load Management Pilot Page 12 FAX. Th pagig option was not selecte Seventy-five pent of the customer chose the e- mal notcaton; eighty-five percent chose the phone noticaon option. Severa chose both. From a qualtative perpetive, parcipants were "pleaant' both by phone or e-mai and would share their thoughts and opinons of the progr frly. A larger scale deloyment would nee to consider the impacts on the conta cente for customer who .'want to chat' with their utity. Agai th progr cre a ."relatonshp" beteen the Copany and the customer. The customers experienced equiment faiur of thir appliance. Al faiur wer determed to be the custmer's equipmet prblem thugh dions diy with th program adtror. For exaple, one cutom believed the DLC switch was acve outside the load- contrl th month causing his watr heaer to not prouce wat. The other two customer equipment problems ocur on forc-ai fuac. One DLC switch was faulty and had to be replaced Fortly, th customer was home at the tie of the event an could hear the DLe switch's contators opning and closig. A tempra remedy of overrding the switch by trppin the cit braker wa ma. Additional events wer not caed on th cutomer unti the intaaton contr could relace the switch. Two of the PCs (therosta) faied one in the warty peod an th oth outside the warty period A vista relac the therosta at Company cost with reaig PC invenor. None of the PCT pacipats use the onle prg fea availe to them. Though the interactive relationship develope custome sha with th Compy the eae of maualy progrng the thostat. However, two paripats with a DLC switc on thir water heaters requested A vista provide on-lie progrmming for water-he control in the futu. Th-nie of the fort cutomer th were radomly selec for an lH pacite by self- instalg the units. The majority of th IH cusomer inca eae of use and that they would recmmnd ths to others, it helpe th be mage thei energy use and they reer to it 2-3 ti per month on average af havig th unt ined fo a yea. Whe customer lie having rea tie energy usage feeback, mos of th parcits indcated they would pay no more than $20 for the IH. Parcipats raed the followig fea as importt: . Savig money . Having re ti energy usag knowledge . An having other featu on the IH such as outdoo tepe. On the other had, opinions about hepi the envinmen equay raed beee not importt an very impot in th sueys. Anecotay, custome reponse var IH pacipats with sever peple in thir household apprecat the abty to ideti spc ener use an then ma modcaons by faly Idaho load Mana.gement Pilot Page 13 members. On th other hand, "empty-nesters" did not find oppnities to reduce use oter than when they next acuire new appliances. Opetional Components Intiat by th Company, Comverge's Load Management Softar (LS) and a local pag servce signed test events and test event durons. The Company's MOM system meaured the effects of shig load durg. peak ties. The LMS and pagg system were successfu 100% of the tie and the MOM system was successfu 90% of the tie. One of th ten test events was not analyze as a result of prlems with the MDM system; data was lost for the Dember 17th, 2008 event. Five miute interval data frm the MDM system was used to deene th resuts of th tet events compar to day pnor, and day af, at the sam ti of day. As show in Appdi A for each of the test events, the DLC equipmnt proved to be succss in pe loa shftg. As expete a "snapback" oc af the releas of the DLC test event and is eaily identiable on the grhs as well. The outcome of ths evaluation metod reveaed th meter interval da meaur usage on the whole buidig and is not grular enough to meaur th effects of demand reponse on individua equipment wìth the one-way demad repons tehnlogy th was deloyed. Therefor, we were unble to valdate individual appliance savigs reulti frm dit loa contrl. Either a two-way demad reponse system or da load logg intaled on a sample would be necessar for ths sort of evaluation. Custome parcipaton (opt-out) was trke mauay by th progr admtrator an noted above in the customer acptace section. The pilot focse on leag cume accptace, and, therefore, the diect peal contact was us for determing ths. For a lager scae progr, an automatd prs using a two-way OLC system would be less advely cursome and subseuently redce progr costs. Peak demad afects A vista's dibution syste in severa ways such as incrsed coduct losses and unpredctable load imbalane. The pilot evaluaed the efect of pe dema on th Company's distribution system.

Th seon wi su how and why the Compy's approach to thse valuaons ha changed and th inuence th th chages may have upon the prospec and design of futu larger deloymts of these tehnologies. . . At th outset of ths piot projec there was th expeon that the pr long-term beefit would include: . an improved undedig of how the DLC teologes co be integr into Avista's existig system, . an unertadig of custome acce of DLC, includig th ra at which they utied the overde provions and the resns to vaou ty and levels of incetives for voluntar parcipaon. .

Most impotly a fu basis was estalished for expeg th controlled devices wi reeive and reac to the curnt signal and customers ar unely to exerce the opt-out proviion in signcant numbers. As a dit consequene of the degre of tehnological reliabilty and th customer's wignes to pennt load contrls to oc .without interptions th Company.has come to view ths progr more as a potential capacity resurce th an energy reource. The value of th energy reductions was found to be smal relative to the prject cost, even when that energy interrption was tightly focused upon the highest cost peod. However, due to the relity of bei able to succesfully euaiload, th cost-effecveness evaluation of ths prouct ca be recste as a reliable capacity resour rather than as an energy reource. The te pilot events coverig a tota of 16 sumer and 14 winter hour rete in an esti reuction of energy usage of 29 kWh's pe parcipatig cutome or approxitely 1,885 kWh's for the tota pilot projec6. Even when optiticaly valuig energ savi at $100 pe mWh and assumg no make-up energy usage afer the interrtion, the tota enegy value of the pilot was $189 for all parcipating customers. If ths two yea pilot were extla to th liely te-year lie7 with a tota of 40 hour of anua intetion, th unscounte cuulative nomial value of those enrg savigs ace to $40 pe custme if the enrgy we valued at $100 pe m Wh8. When comp to th $250 cost of the device and intaaton and a utty cost of $50 pe year to obta volunta custoer parcipaton, it is clea that the ener value doe not offet the incrementa utity cost of ea adtional parcipa home. Additionay, there would be infastrctu costs to the overa progr tht even whe sp over a lager deployment of DLe devices would nevertless add to th cost-ineffecveness of the program when evaluated solely as an ener resource. Altevely, given the reliilty of th tehnology at successfy trg int:miption of subscribe end-uses and the customer's willingnss to forfeit thei option to overr such inteons, the DLC progr ses to have sufcient reliabilty to be viewe as an altee 6 Since th Compy's at. to mere th loa rectOl oc as a reuk of th pilot we frstr by th high th exped varbilty in lo of th over ho it is nesa to contue to rely upo th ongi asumptions of a 05 kW reucton in su usage dug inOl peod an a 15 kW reOl in wite usge.

Given a tota of 40 hour of inteption avaiilty, the probailty of successfuy trggerig the unt at (or very close to) the highest cost or highest natve demand hour of the year is possible. In ths sense, the instaon of the device is acaly establishg a 1.5 kW ten-yea caacity resource that is comparle to a "supe-peakg" generation unt.

Conclusion Th Demand Response piot projec led to key fidigs in two categores explore with the project. These findigs have contrbuted to a fudaenta shi in the maer in which the Company wil evaluate futu simar deployments of DLC as well as estlish critica stag points for the design and ongoing customer seice aspets of prospve larger scae projects. Specifcay, the pilot projec led to a deign which integrtes prven equipment into th unique pre~existig distrbution and communcaton systems that A vist has in pla. Deite the regntion that the equpment ha been succsfuy uti withn oth utties, the integon of the technologies with eah utty's unique distnbution syste was an imt chalenge to overcome. The system design prved to be achievable with th expete cot parete, did not incur any unexp adverse ìmacts or costs on the remader of the distrbution system an reliably communicated th cuint sign to the DLC unts in the field which, in tum, resulted in the expected loa curent. Just as importt as integrating into Avista's system, the practcal caabilties of the tecology was gaig experience with volunta cutomer parcipaon (e.g., optig out),. and progr incentives.

Evaluaon of the cost-effectiveness of future deloyments ca be better based upn the capaity beneft rather th merely energy benefit as a consence of th pilot. As a reult -of this anytca revision the prospet for being able to deign cost-eecve ful-sce progrs is signcay grter.
