Draft for Discussion Purposes Only 5 5 GUIDANCE REQUIREMENTS TO ADDRESS – SUPPLEMENTAL DSIP The Supplemental DISP also presents the opportunity for the utilities to collaborate in the development of initiatives that will have the effect of reducing carbon emissions, including de- carbonizing the transportation system. One such opportunity that should be addressed in the Supplemental DSIP is planning for, and enabling increased deployment of, electric vehicle supply equipment (EVSE). The market growth of plug-in electric vehicles (PEV) will be enhanced by the State’s PEV deployment goals resulting in increasing demand and adoption of PEVs and the corresponding need for EVSE will likewise increase (p. 25) Coordinated statewide approaches by the utilities will directly contribute to market development and decreases in carbon emissions. In addition to new demand on the system resulting from PEV charging service, issues related to vehicle-grid integration will have direct impact on utility operations and planning. Therefore, it is appropriate for the utilities to include consideration of EVSE deployment as part of the DSIP process. (p. 26) While PEV and corresponding EVSE market conditions may vary across the state, early planning should identify and address collaborative initiatives that can set the stage for accelerated market growth. The collaborative planning may also be supplemented by individual utility initiatives, consistent with the collaborative planning for the deployment and integration of EVSE in their service territory. (p. 26) The required engagement plan should also include a description of plans to coordinate and engage with stakeholders including the industry and municipalities in investigating and developing their EVSE deployment approaches or proposals. (p. 26)

Draft for Discussion Purposes Only 7 Current State

Draft for Discussion Purposes Only 8 8 NATIONAL GRID - OVERVIEW Serves approximately 3,800 EV drivers in its upstate New York electric territory, based on vehicle data from R.L. Polk Company Currently operates 66 Level 2 charging stations at public host site locations, with hardware paid for by NYSERDA grants More than 1,200 unique drivers have used them since installation in 2012 Does not believe near-term EV adoption rates will pose significant costs or benefits to the distribution system Potential risks such as overloaded transformers and potential benefits from managed charging may become more significant as adoption grows over time EEI Commitment to Fleet Electrification and Employee PEV Engagement Plans to increase its efforts to enable electric transportation, in order to help NY State advance its ZEV and GHG goals

Draft for Discussion Purposes Only 9 9 NATIONAL GRID - INITIAL 5-YEAR DSIP PLANS Forecasting of Customer EV Adoption and Load Impacts: National Grid will develop probabilistic EV adoption models to forecast customers’ likelihood to buy or lease EVs. These models will inform the Company’s EV customer engagement, and enhance peak impact forecasting over 5, 10 and 15 year time horizons. Residential Rate Option for EV Drivers: National Grid has proposed revisions to the Company’s SC-1 whole-house Voluntary Time-Of-Use (TOU) rate will provide EV drivers a one-time, 12-month trial option. This rate may enable EV drivers to save money while shifting their charging off-peak. Customer Engagement: The Company will develop new customer engagement strategies to educate customers about the benefits of EVs, available federal and state vehicle incentives, and charging options. Public EVSE Development Concepts: National Grid will evaluate potential concepts for utility-led EVSE development, to address specific EVSE market barriers in NY State.

Draft for Discussion Purposes Only 10 CON EDISON OVERVIEW Serves approximately 3500 DMV- registered PEVs and 475 publicly accessible charging stations across its service territory (5 boroughs of NYC and Westchester). Inclusion of emerging technologies like EVs in the future investment plans are critical. Initial DSIP: o Estimates 5-yr cumulative increase in peak load due to EV charging  Peak forecast reflects EVs as load modifiers and as non sector-specific, technology-driven growth o Branch Circuit Energy Management Device pilot project revealed hurdles to using sub-metering for tariff-based off-peak programs o Lessons Learned have been informing the Connected Vehicle Technology pilot, which will be launched later this year to test a non-tariff incentive for promoting off-peak charging and utility-controlled DR using charging data from the vehicle o Includes various EPRI-sponsored projects

Draft for Discussion Purposes Only 11 CON EDISON OVERVIEW Ongoing pilots in progress: o With EPRI & MTA NYC Transit: demonstrate depot and en route electric bus charging o With NYC & MTA NYC Transit: investigate siting of fast charging hubs o With EPRI: Open Vehicle Grid Integration Platform (OVGIP) Pilot uses central server for communication and control between utility and the OEM and vehicles o With EPRI: Medium Voltage DC fast charging demonstration EEI Commitment to Fleet Electrification and Employee PEV Engagement Time of Use Rate o Proposal for EV TOU Rate in current Rate Case o Residential TOU Rate in place with one year price guarantee for EV owners REV Demo RFI planned for Q o Identify new business model to increase EV adoption and create long term value for customers o Solicit private sector proposals  Tailored to NYC’s unique characteristics  Aimed to increase electric vehicle miles traveled, which yields the most social and environmental gains

Draft for Discussion Purposes Only 12 ORANGE & ROCKLAND OVERVIEW ORU estimates a 5 year cumulative increase by 2020 in its system peak demand forecast due to EV charging ORU continues to evaluate customer products and services specific to EVs and PHEVs and monitor future market trends As part of its Advanced Metering Infrastructure (AMI) and Digital Customer Experience (DCX) projects, the proposed AMI infrastructure would be equipped to monitor and collect data on EV charging stations to offer an innovative rate structure in the future. EEI Commitment to Fleet Electrification and Employee PEV Engagement

Draft for Discussion Purposes Only 13 CENTRAL HUDSON Developed a EV forecast in its service territory o EV forecast was based on historical EV registrations and pre-orders and this data was allocated to residential customers on a proportional basis o Granular forecasting for EV is challenging due to low penetration rates and the inability to track infrastructure installed by customers or third parties Expects the increased penetration of EV to help mitigate the reduction in its annual electric system load Foresees advanced metering services and sub metering services playing significant roles in monitoring and planning for EV charging within the service territory Considering a potential REV demonstration project that would aim to reduce "range anxiety" for EV drivers through targeted customer outreach, education and local partnerships

Draft for Discussion Purposes Only 14 AVANGRID AVANGRID expects to gain expertise in integrating and forecasting DER resources like EVs with more granular data from network automation and other platform system investments over next few years. Currently in the initial phases of planning for an EV demonstration project focusing on business models, innovation and third-party partnerships. Plans to utilize customer outreach, marketing and sales programs to communicate new EV projects and services to customers. Will implement technology, software and platform services that will support EVSE, such as AMI and VVO. Demo in Energy Smart Community will assess opportunities based on Iberdrola Spain’s experience to date: o Workplace charging at the Company’s Ithaca office o Public charging stations in the greater Ithaca area and corresponding rate/payment options o Fleet services for businesses o Private ownership models and technology partners
