Adjusted Net Interchange (ANI) - The difference between a market participant's resources and liabilities at a location, measured in megawatt-hours. Resources include generation entitlements, cleared increment offers, external purchases of electric energy, and internal bilateral purchases for electric energy. Liabilities include load obligation, cleared decrement bids, external sales of electric energy, and internal bilateral sales for electric energy.
Assigned Meter Reader - The entity that submits to ISO New England the hourly and monthly megawatt-hours associated with the operation of its asset, which are used for settlement purposes. See ISO New England Manual 28 Market Rule 1 Accounting for additional details.
Auction Revenue Rights (ARR) - Entitlements to receive revenues generated by the sale of Financial Transmission Rights in a specific auction.
Automatic Response Rate (ARR) - For generating resources that are providing regulation service, the amount of the resource's output, in megawatt-minutes, that a market participant is willing to change between the resource's regulation high limit and regulation low limit.
Bid - A request to purchase megawatts at a specific location submitted into the market user interface.
Capability Period - Is one of two specific time periods within a Power Year. The summer period is June 1 through September 30; the winter period is October 1 through May 31.
Claim 10 - The generation output level, expressed in megawatts, that a generator can reach from an off-line state within 10 minutes after receiving a dispatch instruction from ISO New England Operations. This value is required as part of the generator's offer data and is used by ISO New England to evaluate the generator's meeting the New England Control Area's operating- and replacement-reserve requirements.
Claim 30 - The generation output level, expressed in megawatts, that a generator can reach from an off-line state in more than 10 minutes but within 30 minutes after receiving a dispatch instruction from ISO New England Operations. This value is required as part of the generator's offer data and is used by ISO New England to evaluate the generator's meeting the New England Control Area's operating and replacement reserve requirements.
Cleared - When the day-ahead electric energy market has been settled.
Coincidence Peak Load - The sum of all loads at one specific time (date and hour) in the New England Control Area.
Compliance Rating - As part of the regulation monitoring process, a rating that ISO New England gives to regulation providers, which details the provider's degree of compliance with its regulation obligation.
Congestion - A condition that arises on the transmission system when one or more restrictions prevents the economic dispatch of electric energy from serving load.
Congestion component - A part of the nodal price that reflects the marginal cost of congestion at a given node or external node relative to the reference node.
Constraint - Any power system element that operates at or over its limit (e.g., thermal limit, stability limit, or voltage limit).
Control - An action imposed to alleviate a constraint.
Control Area Reliability (CARL) Data - Data submitted to ISO New England for assessing the ability of an external control area to provide electric energy into the New England Control Area to support the unforced capacity offered by the external control area.
Contingency - Any unplanned event where a power system element (lines, generators, and loads) is disconnected from the power system.
Customer of ISO New England - An entity that does business with ISO New England. See Section I.2.2 of the Transmission, Markets & Service Tariff.
