RESPONSE: Cost components of the Utility Ge'neration and Delivery Cost include added energy costs from the additional load of EVs for each year (estimated by the number of EVs multiplied by the average kWh consumption of each EV), and added capacity costs derived by the additional peak load of EVs when the system is capacity constrained beginning in2026. These energy cost components are listed in Table 5 of the Transportation Electrification Plan on page 40 as "Table 5: 2020 IRP energy costs," representing the average incremental energy and capacity cost to serve Avista customers. A more detailed description of these costs can be found in the 2020IRP, pages ll-20 and ll-24. AVISTA CORPORATION RESPONSE TO REQUEST FOR TNFORMATTON ruRISDICTION: CASE NO: REQUESTER: TYPE: REQUEST NO.: IDAHO AVU-E-21-13 IPUC Production Request Staff-06 DATE PREPARED: 10l20l202lWITNESS: N/A RESPONDER: Shawn Bonfield DEPARTMENT: Regulatory Affairs TELEPHONE: (s09) 49s-2782 REQUEST: Please describe how these market transformation progrcms promote energy efEciency. Specifically, please describe how they reduce the amount of energy used. RESPONSE: In terms of electrical energy efficiency, EV energy consumption optimally occurs during off-peak hours of the day and night, utilizing AC Level 2 supply equipment. For example, if more employers provide AC Level 2 workplace charging for commuting employees, a much higher percentage of charging may occur during off-peak daylight hours while the vehicle is parked at work, avoiding on-peak charging in the late afternoons and evenings that coincide with on-peak times throughout the year. A large number of commercial fleet vehicles may similarly be charged during off-peak times of the day and night, at-scale providing for a more efficient delivery of energy for the system as a whole. Furthermore, supplied electricity at Level 2 (240V) compared to Level I (120V), reduces electrical resistive energy losses due to the higher voltage and lower electrical current utilized. ln a broader sense, the most impactful energy efficiency and overall cost savings are realized by the use of electricity as a fransportation fuel, rather than petroleum-derived fuels such as gasoline and diesel. As stated by the U.S. Dept of Energy, "EVs are more efficient than their gasoline-powered counterparts. An EV electric drive system is only responsible for a l5%o to 20%o energy loss compared to 640/o to 75%o for a gasoline engine. EVs also use regenerative braking to recapture and reuse energy that normally would be lost in braking and waste no energy idling . . . EVs are 60Yo to 73Yo efficient, depending upon drive cycle. However, if the energy recaptured from regenerative braking is counted (i.e., recounted when it is re-used), EVs are 77o/o to 100% effi cient." (https://www. fueleconomy. gov/feg/atv-ev.shtml). The typical light-duty EV travels 3.3 miles per kWh, compared to an average of 24 mpg for short wheel base and 18 mpg for long wheel base vehicles in the U.S. in 2019 (Bureau of Transportation Statistics, Average Fuel EfEciency of U.S. Light Duty Vehicles, accessed at https ://www.bts. eov/content/averase-fu el-effi ciency-us-li ght-duty-vehicles). Customers that drive electric consume far less energy on a per-mile basis, paying less than $l/gallon gasoline equivalent, while reducing emissions by 80%o, utilizing a domestic energy source.

Please provide the workpapers in Excel format, with all formulas intact. g. Does the Company anticipate future cost after completion in order to maintain the results and assist future customers with the implementation of this design? RESPONSE: a. Please see the answers below to each part this request. i. Avista has developed a standard DC Fast charging station through the work completed in the pilot and studying what technology is currently available and what the market currently needs. The stations have been designed with expansion in mind. As the market needs change these stations can be upgraded to incorporate higher powered DC chargers. The initial build out for these stations include: l. 500kW Transformer and electric meter. Transformer pad is sized for lMW unit. 2. 480V 3phase electric panel (DC Chargers fed from this panel.) 3. Step down transformer and 240V single phase panel (AC Level II Chargers fed from this panel.) 4. All the underground electrical conduit that runs from the panels to chargers. Conduit is also run to future charger locations. 5. Two 9.6kW AC Level II chargers. 6. One l80kW DC Fast Charger. 7. An additional l80kw DC fast charger can be installed before the transformer needs to be upgraded. The second phase of the build out will add the following: l. The 500kW transformer will be upgraded to a IMW transformer 2. Two 350kW DC super chargers will be installed. ii. Through our research we will incorporate a large battery storage array on site as well as a solar canopy that will cover the battery storage. Wind generation will also be considered. iii. We will propose two use cases. The first will be for areas in our service territory where three phase power is not readily available and there is a need for fast charging capabilities. This situation can arise in many small towns located along major travel corridors. The second will be for areas where our electic grid is capacity constrained and cannot support a IMW charging load without potentially damaging substation transformers. iv. This project will be designed primarily for public charging. There is a growing demand for more public charging that is reliable and includes fast charging capabilities. The addition of onsite storage and renewable generation will enable us to provide reliable and fast charging to more areas in our service territory. In addition, this design could be modified for fleet customers who need DC fast charging and want to offset their fleets energy use with renewables. b. The engineered designs and drawings are not intended to be made available to the general public. They may be used to consult with inquiring customers, supporting private investment in EVSE in Avista's service territory where grid capacity is constrained, and for any DCFC sites that Avista may own and maintain in the future, where appropriate. Fleet customers will have the opportunity to benefit from these designs through fleet electrification consulting services provided by Avista. If this model is a good fit for a customer, we will work with them to leverage the knowledge and standard design afforded by the model. c. The size of the battery storage, solar and wind generation options will be modular in design and optimized at each site to match the outputs of the DC stations and forecasted demand for drivers. The overall layout of the station will need to be tailored to each site's geographical footprint. A grid impact analysis will be conducted for each site. If the site is identified as being grid constrained the size of the battery storage may be adjusted to appropriately match grid constraints. d. This phase will be completed by the end of the third quarter 2023. e. Annual costs for this project are estimate at $25,000. $12,500 will be allocated for internal labor and $12,500 will be allocated or consulting fees. These consulting fees may include conferring with subject matter experts, work with Avista's Grid Innovation Lab, conhols design, and drafting. Please see the Company's response Staff-PR-07-Attachment A. f. Total costs for this project are estimated at $50,000. $25,000 will be allocated for intemal labor and $25,000 will be allocated for consulting fees. Please see the Company's response Staff-PR-07-Affachment A. g. There will need to be periodic updates to the final design as technology evolves. If the design was to be used by a fleet customer there will be labor costs for time spent consulting the customer and managing construction.
