Day-Ahead - The calendar day immediately preceding an operating day.
Day-Ahead Electric Energy Market (DAM) - The financially binding schedule of commitments the day before the operating day for the production and consumption of electric energy, payment of congestion charges, and payment for losses developed by ISO New England as a result of the offers/bids and other specifications submitted in accordance with Section 1.10 of Market Rule 1.
Day-Ahead Internal Bilateral Transaction Trading Deadline - 13:00 (1:00 p.m.) on the first business day after the applicable operating day.
Day-Ahead Load Obligation (DALO) - An obligation acquired by a market participant for the hours when the electric energy at each of the participant's locations equals the megawatt value of the participant's demand bids, decrement bids, and external transaction sales submitted and cleared in the Day-Ahead Electric Energy Market. The DALO is a negative value for settlement purposes.
Decrement Bid - Submission to purchase electric energy at a specified location in the Day-Ahead Electric Energy Market that is not associated with a physical load. An accepted decrement bid results in a scheduled megawatt load at the specified location in the Day-Ahead Electric Energy Market.
Default - When a participant is not in compliance with some section of the Financial Assurance and Billing Policies. The most common types of defaults are payment, financial assurance, and suspension test result.
De-list: Full or Partial - The removal of a specific megawatt amount of unforced capacity from an ICAP resource. Full delisting equals a resource's total capacity. Partial delisting equals less than a resource's total capacity.
Demand - Indicates a consumer of electricity. Means the same as load.
Demand Bid - A request to purchase an amount of electric energy at a specific location. Can also be a request to purchase an amount of electric energy at a specified price associated with a physical load. A cleared demand bid results in a scheduled megawatt load at the specific location. Demand bids submitted for use in the Real-Time Energy Market are specific to dispatchable asset-related demands only.
Economic Dispatch - The selection of generating resources to cover load as inexpensively as possible.
Economic Maximum (EcoMax) - The highest unrestricted level of electric energy (MW) a resource is allowed to generate, representing the highest megawatt output available from the resource for economic dispatch.
Economic Minimum (EcoMin) - The minimum amount of electric energy (MW) available from the generating resource for economic dispatch.
Emergency - Abnormal condition of an electric system requiring manual or automatic action to maintain system frequency or to prevent the involuntary loss of load, equipment damage, or tripping of system elements that could adversely affect the reliability of the system or the safety of people or property. Could also be a fuel shortage requiring departure from normal operating procedures to minimize the use of such scarce fuel or a condition that requires the implementation of emergency procedures, as defined in the ISO New England Manuals.
Emergency Minimum limit (or Emergency Min) - The minimum generation amount (MW) that a generating resource can deliver without exceeding the specified limits of equipment stability and operating permits.
eMkt or EMKT or eMarket - Web-based software application that provides the interface for market participants to submit supply offers, demand bids, increment offers, decrement bids, and regulation offers into the Day-Ahead Electric Energy Market and the Real-Time Energy Market. The application is also used to view market results.
Energy block-hours - Hours associated with the megawatt quantities and prices of electric energy.
Enhanced Energy Scheduler (EES) - Web-based software application used for the submission of external transactions.
External Node - Location on the transmission system that is outside of the New England control area.
External Transaction - A transfer of electric energy that crosses control area borders.
