Updates & Milestones re: Peak Demand Reduction EEAC Consultants (with PA contributions) (Revised, 3/13/17)
Key Work Streams in 2016-2018 Following the Analytical Framework Cost-Effectiveness Framework and AESC Study Demonstrations Evaluation of Demonstrations, Including Evaluation Planning Planning for the 2019-2021 Plan 2
Analytical Framework where are we in the process? The PAs are currently field testing and evaluating solutions Identify the problems Evaluate solutions First round of demonstration projects are in the field Solutions are actively being evaluated, producing data on savings values and customer engagement/satisfaction Analyze costs, risks, and benefits Collecting costs and savings from 2016 projects, will feed into cost-effectiveness models Next Steps: Identify the problems Identify any additional barriers and opportunities arising from demonstration projects, work with system planning to identify T&D areas of constraint Evaluate solutions Revise offerings from 2016, demonstrate new solutions in and 2018; evaluation plan is set through 2018 Analyze costs, risks, benefits Develop cost-effectiveness framework by the end of, ensure all benefits are being accurately captured, next Avoided Energy Cost Study (AESC) to kickoff in summer 3
Analysis of Strategy Options to Obtain Value from Demand Reductions System-level (regional system) and state-level options ISO market resource (bid into the markets) vs. a state resource or utility resource Some wholesale level options (which are likely mutually exclusive): Price: Forward Capacity Market (FCM). Bid into the FCM, receive FCM revenues (to fund programs), and put downward pressure on prices as part of FCM auctions (but note under new rules bidders have a must offer obligation in the energy market and may face penalties under pay for performance; other options to explore) Amount: Installed Capacity Requirement (ICR) and forecast. Reduce the ICR, then states would need to buy less capacity (but note demand resources are reconstituted if bid in) Some retail level options: $ Cost Allocation: ICAP Tag. Reduce demand in peak hour, thereby reducing the share of capacity costs to the load serving entity and some larger customers (the total system cost would not decrease but the share of total system costs paid by MA would) Customer: Reduce customer costs by reducing demand charges and provide other value 4
Cost-Effectiveness Framework where are we in the process? Q1 2016 Q2 2016 Q3 2016 Q4 2016 Q1 Q2 Q3 Q4 Q1 2018 Q2 2018 Review Other Cost Effectiveness Models Presentation to EEAC Peak Demand Subcommittee Cost Effectiveness Issue Discussions 1 Developing/Modifying Cost Effectiveness Framework Present Final Draft Cost Effectiveness Framework to Subcommittee End of AESC Study Assess Cost Effectiveness of Potential Programs RFP and Scope Vendor Selected, Study Commence Results 1. PAs, consultants, and experts continue ad-hoc conversations on cost-effectiveness issues, including: persistence and measure life, impact of participating and not participating in ISO capacity market, treatment of avoided distribution costs, and timing of counting benefits. 5
