Rate Plans
CECONY — Electric
In June 2015, the New York State Public Service Commission (NYSPSC) approved an April 2015 Joint Proposal entered into by CECONY, the staff of the NYSPSC and other parties. Under the Joint Proposal, the rate plan for 2016 does not include a rate increase or decrease. The rate plan for 2016 includes additional revenues from the amortization to income of net regulatory liabilities. The following table contains a summary of the rate plan for 2016:
 
Effective period
January 2016 – December 2016
Base rate changes
None (a)
Amortizations to income of net regulatory (assets) and liabilities
Additional $123 million of net regulatory liabilities (b).
Other revenue sources
Continued retention of $90 million of annual transmission congestion revenues.
Revenue decoupling mechanism
Continued reconciliation of actual electric delivery revenues to those authorized in the rate plan.
Recoverable energy costs
Continued current rate recovery of purchased power and fuel costs (c).
Negative revenue adjustments
Continued potential penalties (up to $400 million annually) if certain performance targets are not met.
Cost reconciliations
Continued reconciliation of expenses for pension and other postretirement benefits, variable-rate tax-exempt debt, major storms, property taxes, municipal infrastructure support, the impact of new laws and environmental remediation to amounts reflected in rates (d).
Net utility plant reconciliations
Target levels reflected in rates are as follows:
Transmission and distribution: $17,929 million
Storm hardening: $268 million
Other: $2,069 million
Average rate base
$18,282 million
Weighted average cost of capital (after-tax)
6.91 percent
Authorized return on common equity
9.0 percent
Earnings sharing
Most earnings above an annual earnings threshold of 9.6 percent are to be applied to reduce regulatory assets for environmental remediation and other costs.
Cost of long-term debt
5.09 percent
Common equity ratio
48 percent
(a)
The impact of 2014 and 2015 base rate changes under the current electric rate plan will continue to be deferred. $249 million of annual revenues collected from electric customers will continue to be subject to potential refund following NYSPSC staff review of certain costs. Revenues will continue to include $21 million as funding for major storm reserve.
(b)
Annual amortization of $107 million of the regulatory asset for deferred Superstorm Sandy and other major storm costs will continue. The costs recoverable from customers will be reduced by $4 million. The costs will no longer be subject to NYSPSC staff review and the recovery of the costs will no longer be subject to refund.
(c)
For transmission service provided pursuant to the open access transmission tariff of PJM Interconnection LLC (PJM), unless and until changed by the NYSPSC, the company will recover all charges incurred associated with the transmission service. In January 2014, PJM submitted to the Federal Energy Regulatory Commission (FERC) a request that would substantially increase the charges for the transmission service. FERC has granted the request and rejected CECONY’s protests. CECONY is challenging the FERC’s decision. In August 2015, PJM submitted a request to FERC that, if approved by FERC, would further increase the charges. In September 2015, CECONY filed a protest to this increase.
(d)
Deferrals for property taxes will continue to be limited to 90 percent of the difference from amounts reflected in rates, subject to an annual maximum for the remaining difference of not more than a 10 basis point impact on return on common equity. In general, if actual expenses for municipal infrastructure support (other than company labor) are below the amounts reflected in rates the company will defer the difference for credit to customers, and if the actual expenses are above the amount reflected in rates the company will defer for recovery from customers 80 percent of the difference subject to a maximum deferral of 30 percent of the amount reflected in rates.

Other Regulatory Matters
In February 2009, the NYSPSC commenced a proceeding to examine the prudence of certain CECONY expenditures following the arrests of employees for accepting illegal payments from a construction contractor. Subsequently, additional employees were arrested for accepting illegal payments from materials suppliers and an engineering firm. The arrested employees were terminated by the company and have pled guilty or been convicted. Pursuant to NYSPSC orders, a portion of the company’s revenues (currently, $249 million, $32 million and $6 million on an annual basis for electric, gas and steam service, respectively) is being collected subject to potential refund to customers. The amount of electric revenues collected subject to refund, which was established in a different proceeding, and the amount of gas and steam revenues collected subject to refund were not established as indicative of the company’s potential liability in this proceeding. At September 30, 2015, the company had collected an estimated $1,889 million from customers subject to potential refund in connection with this proceeding. In January 2013, a NYSPSC consultant reported its estimate, with which the company does not agree, of $208 million of overcharges with respect to a substantial portion of the company’s construction expenditures from January 2000 to January 2009. The company disputed the consultant’s estimate, including its determinations as to overcharges regarding specific construction expenditures it selected to review and its methodology of extrapolating such determinations over a substantial portion of the construction expenditures during this period. The NYSPSC’s consultant has not reviewed the company’s other expenditures. In September 2015, the company, the NYSPSC staff and others entered into a Joint Proposal to settle this proceeding and related matters. The Joint Proposal is subject to NYSPSC approval. Pursuant to the Joint Proposal, the company is required to credit $116 million to customers and, for the period 2017 through 2044, to not seek to recover from customers an aggregate $55 million relating to return on its capital expenditures. In addition, the company’s revenues that were made subject to potential refund in this proceeding would no longer be subject to refund. At September 30, 2015, the company had a $100 million regulatory liability for the remaining amount to be credited to customers related to this matter.
In late October 2012, Superstorm Sandy caused extensive damage to the Utilities’ electric distribution system and interrupted service to approximately 1.4 million customers. Superstorm Sandy also damaged CECONY’s steam system and interrupted service to many of its steam customers. As of September 30, 2015, CECONY and O&R incurred response and restoration costs for Superstorm Sandy of $509 million and $91 million, respectively (including capital expenditures of $148 million and $15 million, respectively). Most of the costs that were not capitalized were deferred for recovery as a regulatory asset under the Utilities’ electric rate plans. Collection from customers of these costs is provided for under the Utilities' current electric rate plans. See “Rate Plans,” above.
In June 2014, the NYSPSC initiated a proceeding to investigate the practices of qualifying persons to perform plastic fusions on gas facilities. New York State regulations require gas utilities to qualify and, except in certain circumstances, annually requalify workers that perform fusion to join plastic pipe. The NYSPSC directed the New York gas utilities to provide information in this proceeding about their compliance with the qualification and requalification requirements and related matters; their procedures for compliance with all gas safety regulations; and their annual chief executive officer certifications regarding these and other procedures. CECONY’s qualification and requalification procedures had not included certain required testing to evaluate specimen fuses. In addition, CECONY and O&R had not timely requalified certain workers that had been qualified under their respective procedures to perform fusion to join plastic pipe. CECONY and O&R have requalified their workers who perform plastic pipe fusions. In May 2015, the NYSPSC, which indicated that it would address enforcement at a later date, ordered CECONY, O&R and other gas utilities to perform risk assessment and remediation plans, additional leakage surveying and reporting; CECONY to hire an independent statistician to develop a risk assessment and remediation plan; and the gas utilities to implement certain new plastic fusion requirements. In October 2015, O&R submitted to the NYSPSC staff the company’s risk assessment and its recommendation that the development of a remediation plan is unnecessary and that the NYSPSC staff determine that the company’s risk assessment activities are complete.

48 percent
(a)
The impact of 2014 and 2015 base rate changes under the current electric rate plan will continue to be deferred. $249 million of annual revenues collected from electric customers will continue to be subject to potential refund following NYSPSC staff review of certain costs. Revenues will continue to include $21 million as funding for major storm reserve.
(b)
Annual amortization of $107 million of the regulatory asset for deferred Superstorm Sandy and other major storm costs will continue. The costs recoverable from customers will be reduced by $4 million. The costs will no longer be subject to NYSPSC staff review and the recovery of the costs will no longer be subject to refund.
(c)
For transmission service provided pursuant to the open access transmission tariff of PJM Interconnection LLC (PJM), unless and until changed by the NYSPSC, the company will recover all charges incurred associated with the transmission service. In January 2014, PJM submitted to the Federal Energy Regulatory Commission (FERC) a request that would substantially increase the charges for the transmission service. FERC has granted the request and rejected CECONY’s protests. CECONY is challenging the FERC’s decision. In August 2015, PJM submitted a request to FERC that, if approved by FERC, would further increase the charges. In September 2015, CECONY filed a protest to this increase.
(d)
Deferrals for property taxes will continue to be limited to 90 percent of the difference from amounts reflected in rates, subject to an annual maximum for the remaining difference of not more than a 10 basis point impact on return on common equity. In general, if actual expenses for municipal infrastructure support (other than company labor) are below the amounts reflected in rates the company will defer the difference for credit to customers, and if the actual expenses are above the amount reflected in rates the company will defer for recovery from customers 80 percent of the difference subject to a maximum deferral of 30 percent of the amount reflected in rates.

Other Regulatory Matters
In February 2009, the NYSPSC commenced a proceeding to examine the prudence of certain CECONY expenditures following the arrests of employees for accepting illegal payments from a construction contractor. Subsequently, additional employees were arrested for accepting illegal payments from materials suppliers and an engineering firm. The arrested employees were terminated by the company and have pled guilty or been convicted. Pursuant to NYSPSC orders, a portion of the company’s revenues (currently, $249 million, $32 million and $6 million on an annual basis for electric, gas and steam service, respectively) is being collected subject to potential refund to customers. The amount of electric revenues collected subject to refund, which was established in a different proceeding, and the amount of gas and steam revenues collected subject to refund were not established as indicative of the company’s potential liability in this proceeding. At September 30, 2015, the company had collected an estimated $1,889 million from customers subject to potential refund in connection with this proceeding. In January 2013, a NYSPSC consultant reported its estimate, with which the company does not agree, of $208 million of overcharges with respect to a substantial portion of the company’s construction expenditures from January 2000 to January 2009. The company disputed the consultant’s estimate, including its determinations as to overcharges regarding specific construction expenditures it selected to review and its methodology of extrapolating such determinations over a substantial portion of the construction expenditures during this period. The NYSPSC’s consultant has not reviewed the company’s other expenditures. In September 2015, the company, the NYSPSC staff and others entered into a Joint Proposal to settle this proceeding and related matters. The Joint Proposal is subject to NYSPSC approval. Pursuant to the Joint Proposal, the company is required to credit $116 million to customers and, for the period 2017 through 2044, to not seek to recover from customers an aggregate $55 million relating to return on its capital expenditures. In addition, the company’s revenues that were made subject to potential refund in this proceeding would no longer be subject to refund. At September 30, 2015, the company had a $100 million regulatory liability for the remaining amount to be credited to customers related to this matter.
In late October 2012, Superstorm Sandy caused extensive damage to the Utilities’ electric distribution system and interrupted service to approximately 1.4 million customers. Superstorm Sandy also damaged CECONY’s steam system and interrupted service to many of its steam customers. As of September 30, 2015, CECONY and O&R incurred response and restoration costs for Superstorm Sandy of $509 million and $91 million, respectively (including capital expenditures of $148 million and $15 million, respectively). Most of the costs that were not capitalized were deferred for recovery as a regulatory asset under the Utilities’ electric rate plans. Collection from customers of these costs is provided for under the Utilities' current electric rate plans. See “Rate Plans,” above.
In June 2014, the NYSPSC initiated a proceeding to investigate the practices of qualifying persons to perform plastic fusions on gas facilities. New York State regulations require gas utilities to qualify and, except in certain circumstances, annually requalify workers that perform fusion to join plastic pipe. The NYSPSC directed the New York gas utilities to provide information in this proceeding about their compliance with the qualification and requalification requirements and related matters; their procedures for compliance with all gas safety regulations; and their annual chief executive officer certifications regarding these and other procedures. CECONY’s qualification and requalification procedures had not included certain required testing to evaluate specimen fuses. In addition, CECONY and O&R had not timely requalified certain workers that had been qualified under their respective procedures to perform fusion to join plastic pipe. CECONY and O&R have requalified their workers who perform plastic pipe fusions. In May 2015, the NYSPSC, which indicated that it would address enforcement at a later date, ordered CECONY, O&R and other gas utilities to perform risk assessment and remediation plans, additional leakage surveying and reporting; CECONY to hire an independent statistician to develop a risk assessment and remediation plan; and the gas utilities to implement certain new plastic fusion requirements. In October 2015, O&R submitted to the NYSPSC staff the company’s risk assessment and its recommendation that the development of a remediation plan is unnecessary and that the NYSPSC staff determine that the company’s risk assessment activities are complete.
