  5. 2015 - 2018 Forecast - Disclaimer The 2015-2018 forecast herein provides an indicative RNS rate trend; it should be used for illustrative purposes only. The estimated data utilized by the PTO AC to develop this forecast of RNS rates is based upon estimated capital additions provided to the Committee by all the New England Transmission Owners. Estimates for 2015 capital additions will be finalized during the normal course of update to the RNS rate effective June 1, 2015 and will reflect more current information. The PTO AC acknowledges that this 2015-2018 forecast is based on a number of assumptions and variables including, among others, estimated project need, design, scope, labor & materials costs, inflation, site & permitting approvals, transmission in-service dates, estimated carrying charges & coincident peak network loads. It is therefore expected that such estimates and assumptions will change over time as more current data become available. In addition, the 2015-2018 forecast reflects gross costs and does not include assumptions pertaining to savings (e.g., associated with congestion, unlocked capacity, etc.) or prior year true-up adjustments.

  6. 2015 - 2018 Forecast - Summary Forecast is preliminary and for illustrative purposes only. Estimates are consistent with the April 2014 RSP and do not reflect revised ISO forecasts. Figures may be off slightly due to rounding.
