Access reports and data sets related to costs for the provision of wholesale electricity in New England, broken down by wholesale load costs, regional network load costs, and emergency energy costs.
The ISO Tariff contains the detailed rules governing the provision of wholesale electric energy, capacity, transmission, reliability, and ancillary and other services in New England, including the allocation of costs and billing for these services. See Section II: Open Access Transmission Tariff (OATT) and Section IV.A: Recovery of ISO Administrative Expenses.
These represent the larger portion of total costs related to the provision of wholesale electricity. Wholesale load costs include energy, capacity, and ancillary market charges, plus related administration and other fees. The monthly Wholesale Load Cost Report (accessible below):

These are charges or payments related to regional network service (RNS). RNS is wholesale electricity transmitted over pool transmission facilities (PTFs)—the network of high-voltage transmission lines and related facilities that the ISO operates. Market participants that sell or buy wholesale electricity pay RNS charges. The ISO then allocates this money among the transmission owners (TOs), which own and maintain the PTFs.
The Emergency Energy Cost Report shows the ISO’s total emergency energy purchases and sales. The ISO participates in cooperative agreements with neighboring power grids to either buy or sell electricity under certain emergency conditions and cost structures. These emergency energy transactions (EETs) are made to relieve abnormal system conditions, such as those that could result in damage to the system or electricity loss, or those that require conservation of a particular fuel during a fuel shortage. (For example, the ISO may request EETs in order to maintain operating reserve during an Operating Procedure 4: Capacity Deficiency event.)
