4 EIM Overview - Background Energy Imbalance Market (EIM) The real-time market to manage transmission congestion and optimize energy imbalance (positive or negative) to balance supply and demand deviations for the EIM Area through economic bids submitted by EIM Participating Resource Scheduling Coordinators in the fifteen and five minute markets. 3

7 EIM Entity Billing Update NVE doesn't issue EIM T+3B invoices to customers NVE Monthly EIM T+12B Regular Invoices have been completed through the Month of September 2017 NVE Monthly EIM T+55B True-up Invoices have been completed through the Month of February 2017 NVE EIM T+9M True-up Invoices have been completed through the Month of September 2016 NVE EIM T+18M Invoices are issued only if the incremental change meets the BPM

8 BPM Changes and Update Under Attachment P, section 8.11 of the OATT, the NV EIM Entity may make corresponding changes to the suballocated charges and payments. To prevent the need for suballocating extremely small dollar amounts, the NV EIM Entity will impose a $10,000 materiality threshold to all MO recalculation settlement statements issued after T+9M as follows: MO settlement statements and recalculation statements issued up to T+9M will be sub-allocated in accordance with Attachment P of the OATT. MO recalculation settlement statements issued after T+9M will be sub allocated only if the incremental change from the prior invoice to the NV EIM Entity shows a total difference of a payment or charge greater than $10,000.
