3 Electric Vehicle Charging Requirements Analysis Page SCOPE 1.1 GENERAL The s Official Community Plan (OCP) includes a target to reduce Richmond s community greenhouse gas emissions 80% below 2007 levels by Richmond s Community Energy and Emissions Plan (CEEP) identifies that to reach this target will require near universal adoption of zero carbon vehicles by the 2040s. The CEEP includes Strategy 7 to Promote Low Carbon Vehicles, and actions pursuant to this strategy. The following report addresses Action 18 of the CEEP, which states that the (The City) will set minimum requirements for EV charging infrastructure in new developments, as part of an objective to reduce energy use and greenhouse gas (GHG) emissions. Accordingly, the City is currently reevaluating policies to improve the provision of electric vehicle (EV) infrastructure in new developments, to better enable wide-spread adoption. Multi Unit Residential Building (MURB) construction represents 58% (24,360 units) of the projected increase in residential dwellings from 2011 to 2041, and is the focus of this report. MURB s inherently include the greatest barriers to EV adoption due to the challenges associated with common property. Community charging infrastructure deployment, which is also a fundamental element in the holistic approach to the provision of EV infrastructure is not addressed in the analysis. The report presents the results of an analysis of EV charging infrastructure requirements for Council s Consideration. The assessment included: Development of definitions for charging infrastructure requirements; Recommendation of mechanisms to better ensure effective implementation of in new strata developments; Assessment of costs and benefits of different EV infrastructure requirements. The intent of the assessment was to identify reasonable, cost effective measures, to achieve the greatest value for money, with consideration afforded to both developers and EV owners, whilst remaining cognizant of the fundamental objective to better enable wide-spread adoption. The following sections provide the results of the assessment for each of the major items indicated above. AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

4 Electric Vehicle Charging Requirements Analysis Page DEFINING EV INFRASTRUCTURE REQUIREMENTS AND TECHNOLOGIES 2.1 GENERAL Definitions for key EV infrastructure configurations are provided in the following sub-sections. Appendix includes definitions for other terminology used in this report. 2.2 INFRASTRUCTURE DEFINITIONS The following definitions for EV infrastructure requirements are recommended. (Electric Vehicle Supply Equipment) installed : All infrastructure required for charging of an electrical vehicle (EV), including all electrical equipment (including metering), cabling and associated raceways, and connections, and Level 2 equipment permanently installed. Energized : All infrastructure required for charging of an electric vehicle (EV), including all electrical equipment (including metering), cabling and associated raceways, and connections, with exception of the Level 2 equipment. Partial EV infrastructure (note: not recommended for inclusion in policy): All infrastructure required for charging of an electric vehicle (EV), including all electrical equipment (including metering), cabling and associated raceways, and connections, up to the provisional branch panelboard locations, minus the feeder cabling to the panelboards. Raceways for the feeder cabling to the provisional panelboard locations would be included as part of the Partial EV infrastructure. The branch panelboards and associated feeder cabling, branch cabling and associated raceways, and connections to s would be installed at a later-date. Although Partial EV infrastructure configurations were assessed, it is not recommended for inclusion in City regulation, as detailed in Section 3.1. Refer to single line diagrams (Appendix D) for further details of the components of the EV infrastructure. 2.3 LOAD MANAGEMENT AND LOAD SHARING Load management and load sharing are control technologies that reduce peak power demand and improve utilization of EV charging systems, thereby reducing electrical infrastructure costs. The technologies also provide the capability to control the time of use, which may be utilized in reducing the impact on the Utility s system. Terminology utilized in this report includes: Load management : Control of the current drawn by the, at the main switchboard of the building. AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

5 Electric Vehicle Charging Requirements Analysis Page 3 Load sharing : Control of the current drawn by multiple on a single circuit, to ensure the capacity of the circuit is not exceeded, and that maximum charging is achieved at each based on the available capacity. A number of EV charging service providers offer with load management and/or load sharing functionality. One business model that has been established is to provide equipment capable of load management and load sharing, as well as metering EV electricity consumption to allow for reconciliation of building electrical costs. Providers offering these smart charging services in the market today typically charge a service fee that is paid by the EV owner. This arrangement is assumed in the life cycle costing in Appendix A. However, some providers are emerging that offer capable of load management and/or sharing that are not based on such a subscription model, and could result in reduced costs for end users. 3.0 RECOMMENDATIONS ON POLICY FOR EV INFRASTRUCTURE 3.1 GENERAL If the City intends for all residents of new multifamily developments to have access to at home EV charging, it is recommended that City policy specify that all residential parking stalls be Energized. As part of the Terms of Reference for this study, the City requested commentary on the following question: For parking stalls that are not Energized, should the City specify that remaining stalls feature a Partial EV Infrastructure configuration? The proponent should propose a Partial EV Infrastructure definition that can be included in City regulation. The proponent should then describe the benefits and drawbacks of including this definition in City regulation, and recommend whether it be included. Although Partial EV infrastructure configuration specifications were developed, it is not recommended that the City make reference to this configuration in the requirements due to: Higher costs associated with completion of the installation at a later-date. Appendix B includes Partial Infrastructure costing analysis; Additional time associated with completion of the installation at a later-date; Delays in gaining strata approval; Extending the sales cycle (awaiting installation of charging infrastructure); Common property complications associated with apportioning of costs; Reasonable costs associated with Energized infrastructure; Complications with parking stall re-assignment; AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

6 Electric Vehicle Charging Requirements Analysis Page 4 Disincentive of additional costs for the EV owner, which is contrary to the initiative to encourage EV adoption (i.e. Demand elasticity is high (between 3.0 and 4.0), which means sales are significantly impacted by price); Inclusion of Partial EV infrastructure assumes EV adoption will follow a linear progression as opposed to exponential, which is contrary to the historical record for disruptive technologies. Analysis identifies that Partial EV infrastructure provision represents significantly higher final costs compared to complete (Energized) installations. Depending on building archetype and design, selected infrastructure configuration, and extent of partial provisions, the increase in final costs (with the exception of the townhouse archetype) ranges from 20% to well over 700%. Refer to Appendix B for a summary of results of the Partial EV infrastructure costing analysis. Given acceptance that EV adoption is required to meet GHG emission reduction targets, and widespread projections for exponential growth in uptake of EV s, the logical conclusion is that provision of Partial EV infrastructure incurs additional time and cost on future buildings owners and residents, and is contrary to the objective to better enable wide-spread adoption. On this basis, complete EV infrastructure installation (Energized) should not be viewed from the perspective of an additional cost compared to Partial EV infrastructure, but more appropriately, a cost savings compared to Partial EV infrastructure. 3.2 MINIMUM PERFORMANCE LEVELS As part of the Terms of Reference for this study, the City requested commentary on the following question: Should the City specify a minimum performance level for EV Infrastructure (e.g. a kw minimum; or average and maximum kwh overnight delivered to stalls)? This could preclude load managed designs that provide insufficient power to effectively charge vehicles. The proponent should recommend whether a minimum performance level is necessary, and recommend a performance level if so. The recommended minimum performance level is: A minimum performance level of 12 kwh per, over an eight (8) hour overnight period. Load management and/or load sharing may be implemented. Refer to Appendix G for details of the basis for the minimum performance levels. Analysis indicates that a 40A 208V connection to each parking stall, with circuit sharing of up to four stalls per branch circuit, or equivalent (additional chargers on a circuit of greater ampacity) is sufficient to provide the minimum charging requirement. This is based on provision of load sharing to maximize utilization of circuit ampacity, and to benefit from the capacity pooling effect of sharing, in lieu of restricting each charger to a maximum of 25% of the circuit ampacity.

7 Electric Vehicle Charging Requirements Analysis Page 5 The above statements should not be interpreted to preclude the use of alternate configurations to achieve the minimum performance level. It is highlighted that it is not the intent to limit the options of designers, only to establish a minimum performance level to be achieved. A minimum performance level is necessary to ensure an appropriate experience for the EV owner, thereby encouraging EV adoption. It is understood that the City may wish to entertain reduced performance requirements, including Level 1 charging, in some specific instances where average driving distances of residents of a specific building are considered atypical/limited. It is highlighted that the industry is generally coalescing around Level 2 charging due to the reasons of performance requirements (average driving distances) and consumer expectation. Level 2 charging is considerably more consistent with the objective to better enable widespread adoption, and represents a lower initial infrastructure (not including ) installation cost than Level 1 charging where load sharing is implemented. Should there be specific instances where the City considers reducing the requirement to Level 1 it is recommended that some level of performance augmentation, such as the installation of a number of dedicated Level 2 or DC fast chargers, be considered. Metering issues inherent with Level 1 charging would also need to be carefully considered in any such instances. 3.3 ACCOMMODATING LOAD MANAGEMENT AND LOAD SHARING As part of the Terms of Reference for this study, the City requested commentary on the following question: Should the City make any special requirements to ensure that EV infrastructure configurations designed for load management will be able to be used by building occupants? E.g. Should an EV charging infrastructure design be shown to be compatible with specific EV charging service providers offerings (or multiple different service providers)? Should a contractual relationship with an EV charging service provider be demonstrated? The proponent should recommend any requirements appropriate for the City to pursue during its development approvals process. The recommendation is to not preclude load management/load sharing configurations, as many are capable of achieving the minimum performance level, and are cost effective installations. The process of amendment to CSA C22.1 (refer to Appendix F for further details) to clarify the allowance of load management, is in progress. Requirements should allow designs to be based on any system capable of achieving the minimum performance level, and not favor a specific vendor. Contractual relationship with an EV charging service provider whilst to be encouraged for reasons of quality of service, is not necessarily recommended for inclusion in City regulation. Requirements proposed for inclusion during the development approvals process are the definitions and minimum performance levels. Load sharing solutions provide the opportunity to significantly reduce infrastructure costs by avoiding the inherent high costs of dedicated circuits. A Level 2 load sharing installation is less than one-third the cost AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

8 Electric Vehicle Charging Requirements Analysis Page 6 of a dedicated circuit installation; and even less than a Level 1 dedicated circuit installation. Historically, installations and Codes have been based on dedicated circuits. Analysis identifies there are significant opportunities for cost reductions through the implementation of load management and load sharing solutions. The trade-off for the cost benefit is reduced performance and restriction on selection. A minimum performance level requirement, as designated in Section 3.2 addresses the performance issue. In terms of selection, the equipment must be capable of load sharing, which means a networked, as opposed to standalone. At present equipment from various manufacturers is not open protocol and cannot work in a sharing arrangement with equipment from other manufacturers. This means a requirement (at present) to select one manufacturer, at least for each shared circuit, and more realistically/appropriately for each building. Additional benefits of networked systems include monitoring and maintenance features, thereby improving the experience for the EV owner, which better enables wide-spread adoption. It is anticipated that in the future all chargers will be smart chargers with increased features and range of available services and capabilities, eventually including open protocols to allow greater selection and interconnection of equipment. It is also anticipated that capabilities will further develop in relation to instantaneous monitoring of available building electrical capacity to maximize charging performance whilst minimizing infrastructure costs. 3.4 BILLING SYSTEMS To ensure electricity consumption costs are appropriately apportioned to EV owners it is recommended that revenue grade metering (one meter) be provided on electrical distribution equipment feeding equipment. Apportioning of costs as opposed to resale of electricity may then be performed via metering integral to the equipment. Alternatively, as is the case in 20 US states currently, resale of electricity by the strata organization may be performed based on metering integral to equipment, once issues with the BC Utilities Commission Act (and other regulations) are resolved. 3.5 MECHANISMS TO ENSURE AVAILABILITY OF CHARGING The recommendation to avoid Partial EV infrastructure minimizes potential restrictions to charging availability and avoids complexities inherent with parking stall re-assignment. However, it does not eliminate all possible impediments to an EV driver being able to charge. Provincial Right-to-Charge legislation similar to that enacted by the State of California (on September 21, 2014) would ensure availability of charging to MURB residents. Costs associated with the purchase and installation of equipment, electricity consumption costs, and ongoing maintenance of the equipment would be AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

9 Electric Vehicle Charging Requirements Analysis Page 7 borne by the EV owner. Costs associated with Energized provisions would be borne by the developer of the property. California s Right-to-Charge legislation is included in Appendix H. staff have noted their preference for effective provincial Right-to-Charge legislation to ensure access to EV charging in buildings subject to EV infrastructure requirements. In the potential absence of provincial action, City staff note that Right-to-Charge provisions may be included in strata bylaws and/or covenant, which could be secured through rezoning and development approval processes. Potential clauses for such mechanisms are included in Appendix H. 4.0 ASSESSMENT OF DIFFERENT EV INFRASTRUCTURE REQUIREMENTS 4.1 LIFE CYCLE COSTING Analysis identifies the opportunities for significant cost savings through the implementation of load managed and load shared solutions. While the life cycle cost for the 100% AC L1 energized (dedicated) configuration represents the lowest cost over a 20-year period (due to the absence of the Level 2 charger and EV service costs) it comes at the cost of performance. The 100% AC L2 energized (4-way load shared and load managed) configuration represents the least expensive option assessed as achieving the recommended minimum performance level. It also represents the least expensive initial cost of any option (including the 100% AC L1 energized (dedicated) configuration), at an average of $561/stall for the four archetypes. EV service costs include all provider service charges, including incorporation into the provider system, configuration of chargers, monitoring (operation, usage), control of access to chargers (users, time), 24/7 remote support, generation of reports, and software updates. Refer to Appendix A for a complete summary of results of the costing analysis. Cost estimates were primarily developed using RSMeans 2017, with additional review by Mott Electric GP. 4.2 QUALITATIVE COMMENTARY In accordance with Section 3.2 a minimum performance level of 12 kwh (over an eight-hour period), which corresponds to a 65km of charge range is considered a reasonable compromise between performance and price, for a MURB installation in the. The 100% AC L1 energized (dedicated) configuration provides the lowest charging rate at 1.4kW, and the 100% AC L2 energized (dedicated) configuration provides the highest charging rate at 6.3kW. Refer to Appendix G for details of charging rates for the various configurations. AES Engineering Ltd Granville Street, Vancouver, BC, Canada V6Z 1M7 P F

10 Electric Vehicle Charging Requirements Analysis Page CONCLUSIONS 5.1 RECOMMENDATIONS The cost analysis identifies the 100% AC L2 energized (4-way load shared and load managed) configuration as a reasonable compromise between price and performance. It also avoids concerns inherent with Partial EV infrastructure installations. Whilst it has been identified as a reasonable solution, it should not preclude other configurations or favor a specific vendor. It is recommended that alternate configurations that can reasonably be verified to achieve the minimum recommended performance level for a specific installation, be deemed acceptable. Solutions that provide an improved performance level are particularly encouraged, to inspire range confidence and maximize the experience for the EV owner, thereby further encouraging EV adoption. For example, a minimal provision (1% - 2% of stalls) of DC Fast charging (in suitably accessible locations) for larger developments (>100 stalls), whilst not included in the recommendations, is encouraged for consideration during the development process, to increase EV adoption, sustainability, and marketability of the development. It is understood the City may have the ability to offset costs associated with EV infrastructure through reduction in the required/designated number of parking stalls. Through implementation of load managed and load shared solutions (as opposed to dedicated circuits) the reduction in parking stalls necessary to offset costs would be minimal (2% 3%). A reduction in parking stall numbers would also be consistent with the trend towards reduced vehicle ownership, increased sharing options and membership, and associated potential future impacts of autonomous vehicles. The larger disruptive technology of battery storage (which EV s are a component) can be expected to play a role in influencing charging infrastructure and equipment in the future. Autonomous and wireless technologies are also expected to impact requirements in the longer-term. We understand that the recommendations are likely to inspire considerable comment and debate from the many and varied stakeholders. For this reason, we recommend further consultation with the various stakeholders, to ensure appropriate opportunity for expression of opinions and due consideration, prior to implementation of any final requirements. With the increasingly rapid developments inherent with this disruptive technology, the perception of the recommendations is also likely to change within a short period of time, and the consultation period would provide such time.
