In FCTS, pipeline analysis plans: Assigned to new demand capacity resources for the 11th and 12th forward capacity auctions (FCAs) will be removed from FCTS Will not be assigned new pipeline analysis plans at the conclusion of each FCA effective with the conclusion of FCA 13
Competitive Auctions with Sponsored Policy Resources (CASPR) Implement a substitution auction (SA) to be run after the primary Forward Capacity Auction (FCA) to coordinate the entry of new sponsored policy resources (SPRs) with the exit of older existing capacity resources willing to permanently retire; this pairing of entry and exit minimizes the impact that SPRs have on competitively-based capacity prices, maintains resource adequacy, and reduces over-supply concerns	Forward Capacity Auction participants with one of the following: New sponsored policy resource Existing generating capacity resource with either a full or partial retirement delist bid, or qualified capacity seeking to participate in the SA as demand Import resource with an external elective transmission upgrade with either a full or partial retirement delist bid, or qualified capacity seeking to participate in the SA as demand	February 4, 2019	Forward Capacity Tracking System (FCTS)	Participants requesting to qualify a new resource as an SPR will use FCTS to: Elect to participate in the SA via a show of interest (SOI) Provide documentation in the new capacity qualification package certifying that the new resource is a an SPR Submit final supply offers for the FCA qualified capacity, if qualified as an SPR Participants with an existing generating capacity resource or import capacity resource with an external elective transmission upgrade will use FCTS to: Elect to participate as demand in the SA Submit demand bid quantities
			Financial Assurance Management System (FAM)	FAM will be updated to determine exposure and adjust the FA requirement as necessary for the following: Negative-priced supply offer segments submitted by SPRs Existing resources that elected, in a prior FCA, to have their CSO and capacity clearing price continue to apply after the applicable capacity commitment period, and then submitted a demand bid into the SA at a price greater than the rate-lock price.
			Substitution Auction	Participants with a new SPR will be prevented from electing a multi-year CSO and capacity clearing price for any capacity that clears in the SA Participants with an existing resource that will participate in the SA as demand will be prevented from: Designating it as self-supply Including it on an offer composed of separate resources Automatically matching it to an offer The SA supply offer of an SPR receiving a CSO in the primary FCA will be reduced by the difference between its qualified capacity and its awarded CSO. The demand bid from an existing resource that exceeds the CSO awarded to that resource in the primary FCA will be reduced to equal the awarded CSO.
			MIS	FCA Auction Results MIS Report will be updated to include results from the SA.
Customer Contact Center Solution (CCCS) Replace the current Ask ISO platform to improve participant-issue management and contact identification by integrating voice, email, and case-tracking systems, as well as to address business continuity goals	All participants and stakeholders submitting inquiries to ISO New England via phone, email, or Ask ISO	August 27, 2018	Ask ISO	Users submitting inquiries directly to the Ask ISO application will be able to access the system with their unique email and password, instead of with the existing digital certificate access process. A self-service support community will be available to allow users to search knowledge articles for frequently asked questions, to submit inquiries, and to categorize issues to expedite system access and issue routing.
		August 27, 2018	CAMS	Phone, email, and other contact data will be shared between the Customer and Asset Management System (CAMS) and Ask ISO to create user accounts and update contact information.

			Demand Response Market User Interface (DRMUI)	The DRMUI will allow download of three baseline types (weekday, Saturday, Sunday/Holiday), baselines for prior days, interval performance data by asset, and interval performance data by resource.
			Baseline calculations	Baseline calculations for Saturdays and Sunday/DR holidays will use the five most recent uninterrupted like-days during the past 42 days rather than non-holiday weekdays as implemented June 1, 2017.
			Forward Capacity Tracking System (FCTS)	Existing DR field labels in the UI will be updated to new PRD terms which will also display in historical views with the old DR data model.
			Settlements	DR will be settled via the established two-settlement process where RT market quantities are used to determine participants’ actual operation deviations from their day-ahead (DA) energy positions. Real-time Net Commitment-Period Compensation hourly shortfall will be introduced.
			Market Information Server (MIS)	New reports will be introduced as well as others being retired.
			Web services and web publishing	New eMarket WebServices upload/download and XML functionality for DRRs will utilize new DRR terminology. The Morning Report will include DRR capacity.
Forward Capacity Market Pay-for-Performance (FCM PFP) Replace the FCM availability metric with a performance metric based on measurable energy delivered and reserves provided	Lead market participants for all resources	June 1, 2018	Financial Assurance Management (FAM)	The potential for resources with capacity supply obligations (CSOs) to have negative capacity payments under the new PFP rules will be collateralized by adding a financial assurance requirement for Forward Capacity Market delivery.
			Settlements	Performance deviations during a reserve deficiency will be settled using the two-settlement approach in which over-performing resources are credited and underperforming resources are charged at a pre-specified rate. A stop-loss mechanism will be introduced to ensure resource owners do not face unlimited losses for non-performance. Every resource will be eligible for performance payments, whether or not it has a CSO.
			Forward Capacity Tracking System (FCTS)	Lead participants of passive resources will submit a show of interest (SOI) to be eligible for capacity performance payments (CPPs) when performing during a scarcity condition. (The eligibility for CPPs to be paid for external transactions, generators, and demand response resources that are not mapped to a resource will be determined through the settlement process.)
			Enhanced Energy Scheduler (EES)	Flex reservations will no longer be an option.
			ISO New England SMD Applications	The supplemental availability designation user interface will be retired. The supplemental availability bilateral option will be replaced with a capacity performance bilateral option within the internal transactions user interface. The Submit Meter Reading user interface will require all 24 hours to be reported, CSV and XML formats will change, terminology will be updated.
			Web services	A new scarcity conditions report will be available.
			Market Information Server (MIS)	New reports will be introduced and others will be retired.
Subhourly Settlements (SHS) Transition the settlement interval from hourly to every five minutes to align with the real-time dispatch instruction and pricing intervals for the Real-Time Energy Market, Regulation Market, Net Commitment-Period Compensation (NCPC), and reserve markets for generators, load resources, and external transactions	Lead market participants submitting Roseton node external transactions, owners of resources that can respond quickly to dispatch instructions, data-scrapers using HTML client programs, and meter reading submitters	Implemented phases: March 1, 2017: transition to five-minute settlement interval August 1, 2017: five-minute meter reading submittal allowed as an optional feature December 1, 2017: implement five-minute interval settlement for regulation capacity and regulation service	Meter reading CSV and XML upload and download files	Affected participants will continue to submit hourly data values to the ISO at the project go-live.
