Real-Time - The current operating day.
Real-Time Energy Market - This market reconciles differences between the amounts of energy scheduled before an operating day and the actual loads of the operating day, market participant re-offers, hourly self-schedules, self-curtailments, and any other changes that impact real-time system conditions.
Real-Time Internal Bilateral Transaction Trading Deadline - 13:00 on the second business day after the applicable operating day.
Real-Time Prices - Locational marginal prices resulting from the dispatch of power within the operating day.
Redeclaration - Restatement of a resource's availability, limits, or other offer or bid parameters, except price-related supply offer data, which market participants submit to ISO New England and that reflect changes in the status or capability of the participant's resource. Also, changes that ISO New England makes to a resource on the basis of the resource's actual performance.
Regulation - The capability of a specific generator equipped with appropriate telecommunications, control, and response capability to increase or decrease its output in as a result of a regulating control signal from ISO New England.
Regulation Charge - The hourly regulation clearing price (RCP) charged to each participant that buys regulation from the Regulation Market, which equals the amount of regulation purchased to meet the participant's hourly regulation obligation.
Regulation Clearing Price - The hourly price at which regulation will be sold in the Regulation Market, which is based on submitted offers from generators designated to provide automatic generation control (AGC) in that hour.
Regulation Market - An ISO New England market that compensates generators for providing instantaneous responses in generation output. ISO New England designates a set of generators to provide automatic generation control (AGC) and calculates an hourly clearing price based on submitted offers for the generators providing AGC in that hour.
Regulation Monitoring - The testing and auditing of generators providing regulation to ensure that they reliably meet their regulation obligations.
Regulation Obligation - A participant's pro-rata share of the hourly regulation requirement, as adjusted for the regulation actually assigned in real time. Calculations are detailed in Section 4 of ISO New England Manual 28 .
Regulation Offer - An amount of generation, in whole megawatts, submited into the eMarket application to provide a given amount of regulation.
Regulation Requirement (or ISO Regulation Requirement) - The hourly megawatt amount of regulation ISO New England requires to maintain system control and reliability.
Reliability Must Run Resources - Resources scheduled to operate out-of-merit order and identified by ISO New England as necessary to preserve the reliability of a Reliability Region. RMR resources provide local voltage or VAR support or meet local regulation or operating-reserve requirements.
Reliability Regions - A defined region of the New England Control Area that reflects the operating characteristics of, and the major transmission constraints on, the New England transmission system.
Re-offer Period - Normally, the period between 16:00 and 18:00 the day before the operating day when market participants submit revised supply offers and revisions to demand bids for any dispatchable asset-related demand resources. The hours may change depending on software impacts or other events.
Reserve Adequacy Analysis - The analyses ISO New England performs at the close of the re-offer period to ensure that adequate resources are committed to meet the forecasted load and operating reserve requirements for the Real-Time Energy Market.
Resource - A generating resource, a dispatchable load, an external resource, or an external transaction.
R-Factor - The multiplier used in calculating reserve requirements equal to 1.3.
