•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.
