Real-Time Energy

What is Real-Time Energy?

Real-Time Energy is the balancing settlement for the quantity deviations from each Participant's Day-Ahead Energy Market obligations, as metered in the operating day. The Participant's hourly Real-Time Energy credits and charges are calculated by multiplying the net deviation at each location by the Real-Time Locational Marginal Price for that location. The invoice amount to a Participant is the net of the Participant's hourly credits or charges, plus allocations of the hourly Marginal Loss Revenue and Inadvertent Energy credits or charges, for the billing period.

Primary provisions for the settlement of the Real-Time Energy Market are included in, but not limited to, Market Rule 1 and ISO New England Manual for Market Rule 1 Accounting Manual M-28.
