The variance in energy supply procurement costs is offset in Operating Revenues (tracked energy supply procurement revenues).  The variance in other electric distribution costs for the three month period is due to higher long-term contractual energy-related costs that are recovered in the non-bypassable component of the FMCC mechanism at CL&P, an increase in the long-term renewable energy contract cost deferral and higher net metering costs at NSTAR Electric, partially offset by a decrease in long-term renewable energy purchase contract costs at both NSTAR Electric and PSNH.

Included in transmission costs are charges that recover the cost of transporting electricity over high-voltage lines from generation facilities to substations, including costs allocated by ISO-NE to maintain the wholesale electric market.

•The decrease in transmission costs at CL&P was due primarily to a decrease resulting from the retail transmission cost deferral, which reflects the actual costs of transmission service compared to estimated amounts billed to customers and a decrease in Local Network Service charges, which reflect the cost of transmission service provided by Eversource over our local transmission network.  The decrease was partially offset by an increase in costs billed by ISO-NE that support regional grid investments.

•The increase in transmission costs at NSTAR Electric was due primarily to an increase in costs billed by ISO-NE that support regional grid investments, partially offset by a decrease in the retail transmission cost deferral and a decrease in Local Network Service charges.

•The increase in transmission costs at PSNH was due primarily to an increase in costs billed by ISO-NE that support regional grid investments and an increase in Local Network Service charges.  These increases were partially offset by a decrease resulting from the retail transmission cost deferral. 

Operations and Maintenance expense includes tracked costs and costs that are part of base distribution rates with changes impacting earnings (non-tracked costs).  The variance in Operations and Maintenance expense is due primarily to the following:
