This document discusses the goals, design, and shortcomings of the Fast Start Pricing in NEPOOL markets. It also provides additional information and evidence on the impact of start-up and no-load amortization during recent winters. The anticipated schedule for implementing the Fast Start Pricing is also outlined.

june 3, 2015 | NEPOOL markets committee Jonathan Lowell Market development Price Formation When Fast Start Resources Are Committed and Dispatched Fast Start Pricing
Quick Review - Goals of the Fast Start Pricing Design • Improve price formation by reflecting the cost of fast-start deployments through transparent market price signals. • Improve performance incentives for all resources during tight system conditions when reliability risk is heightened. • Address External Market Monitor’s recommendations • Address shortcomings of current Fast Start Pricing: • Shortcoming #1 - Fast Start assets are generally unable to set price after the first dispatch interval, even though committed and dispatched economically • Shortcoming #2 - Relaxing EcoMin values in the dispatch solution distorts the system energy balance
Fast Start Pricing Design in a Nutshell • RT Dispatch solution • Respects physical limits • Determines DDPs • RT Pricing solution • EcoMin values of committed Fast Start resources relaxed to zero • Amortization of commitment costs • No Load cost amortized over EcoMax • Startup cost amortized over EcoMax during Minimum Run Time • Determines energy and reserve prices • Lost opportunity cost payment when a resource is dispatched to a DDP less than its “economic dispatch point”
Additional Information Available! • These documents are posted (or re-posted) for the June MC meeting: • Memo: “Fast-Start Pricing Improvements – Revised Edition” • Detailed explanation of Fast Start Pricing logic, rationale and examples • New Memo: “Amortization of Startup and No Load Costs in the ISO’s Fast Start Pricing Proposal” • Summary of Startup & No Load discussion from May MC meeting supporting the continued inclusion of amortized SU & NL costs n Fast Start Pricing • New Memo:“Fast-Start Resource Pricing – Market Rule 1 Redlines” • Summary of tariff changes to implement Fast-Start Pricing • Powerpoints: • March MC meeting - “Fast Start Pricing” presentation • Includes examples from the memo and discussion of Fast Start Pricing design principles • April MC meeting - “Fast Start Pricing” presentation • Includes impact analysis and simulation results • May MC meeting - “Fast Start Pricing” presentation • Detailed discussion of stakeholder issues identified at the April MC meeting • Analysis of FCM cost reductions related to Fast Start Pricing
Impact of start-up & no load Amortization during recent winters Further Evidence that Winter 2014 was Highly Unusual, and Likely Not Indicative of Future Fast Start Pricing Impacts
Impact of SU/NL Amortization – Winter 2014 was Very Unusual • The FS Units with the highest SU & NL costs were dispatched far more often in 2014 than in the prior or subsequent years • Supports the analysis presented at the May MC meeting suggesting estimates of future FS Pricing impacts should discount January-March 2014 Fast Start Units with Highest Observed SU/NL Adders in 2014
Anticipated Schedule • February MC meeting – conceptual overview • March MC meeting • Lost Opportunity Cost discussion • Detailed Examples • April MC meeting • Historical simulation of fast start pricing design impacts • May MC meeting • Review Fast Start Pricing design and impacts • Tariff language review • June MC meeting – request MC vote • Quick review of design • Tariff language review • June PC Summer Meeting – request PC vote • FERC filing – summer 2015 • Implementation targeted for late 2016 or early 2017
