Financial Transmission Rights (FTR) - An entitlement associated with congestion that equals the amount of electric energy (MW) flowing in one direction between two specific locations. The FTR holder might incur an obligation to pay a charge or receive revenues.

Forward-Reserve Strike Price - The Forward-Reserve Heat Rate multiplied by the Forward-Reserve Fuel Index.

Generator Marginal Cost - The price at which a participant has offered to supply an additional increment of electric energy from its generating resource.

Host Participant Meter Readers - The entities responsible for submitting ICAP-related data to ISO New England, as identified by a host participant, a market participant, or both and designated as such during ISO New England's Asset Registration Process.

Host Participant - A transmission or distribution provider that reconciles the loads within ISO New England's metering domain.

Hub - A specific set of predefined nodes for which locational marginal prices are calculated and used to establish a reference price for electric energy purchases and the transfer of day-ahead adjusted load obligations and real-time adjusted load obligations and for the designation of Financial Transmission Rights.

Increment Offer - A Day-Ahead Energy Market offer to sell electric energy at a specified location. An accepted increment offer in the Day-Ahead market results in scheduled generation at the specified location.

Injection - A location on the transmission system where generation is injected (a.k.a. source).

Installed Capacity (ICAP) Market - The buying and selling of the megawatt capability of from qualifying ICAP resources that meet the requirements set forth in Market Rule 1 and ISO New England Manuals.

Installed Capacity Equivalent - The capability of a resource corresponding to its unforced capacity, calculated in accordance with ISO New England's administrative procedures.

Installed Capacity Requirement - The level of capacity required to meet the reliability requirements for the New England control area, used to determine an Unforced Capacity Requirement for market participants.

Installed Capacity (ICAP) Resource - A generating resource, dispatchable load, external resource, external transaction, or demand resource that meets the qualification requirements of Market Rule 1 and has been designated as an ICAP resource by a market participant.

Intermittent Power Resource (IPR) - A resource whose output amount and availability are intermittent and not subject to the control of ISO New England or the plant operator because of the intermittent source of fuel (e.g., wind, solar) the resource uses or contractual obligations (e.g. qualifying facilities). IPRs can be resources having less than 5 MW operating within the distribution system.

Internal Bilateral for Load (IBL) - An IBT in the Real-Time Energy Market is when the buyer receives a reduction in load obligation and the seller receives a corresponding increase in load obligation in the amount of the megawatt sale.

Internal Bilateral for Market (IBM) -

  1. An IBT for Energy under which the buyer receives a reduction in its day ahead adjusted load obligation and a real time adjusted load obligation while the seller receives a corresponding increase in its day ahead adjusted load obligation and in its real time adjusted load obligation in the amount of the megawatt sale. (An IBT for Energy can apply in the Day-Ahead Energy Market and Real-Time Energy Market or just the Real-Time Energy Market.)

    and/or

  2. An IBT for Regulation under which the buyer receives a reduction in the regulation obligation and the seller receives a corresponding increase in the regulation obligation in the amount of the megawatt sale.

Internal Bilateral Transaction (IBT) - The purchase or sale of electric energy or regulation obligations between two market participants internal to the New England control area.
