Rate Filings	Rate Filings This Note should be read in conjunction with Note 6. Regulatory Assets and Liabilities to the Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended December 31, 2017. In addition to items previously reported in the Annual Report on Form 10-K, significant regulatory orders received and currently pending rate filings with FERC and the BPU by PSE&G are as follows: Electric and Gas Distribution Base Rate Filings—In October 2018, the BPU issued an Order approving the settlement of PSE&G’s distribution base rate case with new rates effective November 1, 2018. The settlement resulted in a net reduction in overall annual revenues of approximately $13 million, comprised of a $212 million increase in base revenues, including recovery of deferred storm costs, offset by the return of tax benefits of approximately $225 million. The tax benefits include the flow-back to customers of excess accumulated deferred income taxes resulting from the reduction of the federal income tax rates provided in the Tax Cuts and Jobs Act of 2017 (Tax Act) as well as the accumulated deferred income taxes from previously realized tax repair deductions and tax benefits from future tax repair deductions as realized. As a result of the agreement to flow back tax repair-related accumulated deferred income taxes in the settlement, PSE&G recognized a $581 million regulatory liability and a corresponding regulatory asset as of September 30, 2018. The Order provides for a $9.5 billion rate base, a 9.6% return on equity for PSE&G’s distribution business and a 54% equity component of its capitalization structure. In addition to the $13 million annual revenue reduction, the Order provides for a $28 million one-time refund to customers in November and December 2018 for taxes collected at the higher federal income tax rate for the January 1 to March 31, 2018 period. The BPU approved a rate reduction effective April 1, 2018, to PSE&G’s then current electric and gas base rates of approximately $71 million and $43 million, respectively, on an annual basis, to reflect the lower federal income tax rate for the period April 1 and forward. Transmission Formula Rate Filings—In October 2018, PSE&G made two FERC filings with respect to its Transmission Formula Rate. PSE&G filed its 2019 Annual Transmission Formula Rate update with FERC requesting approximately $100 million in increased annual transmission revenue effective January 1, 2019, subject to true-up. In addition, PSE&G filed a Section 205 filing that seeks FERC approval to refund approximately $155 million of transmission related “unprotected excess deferred income tax benefits” to transmission customers over the 2019 twelve month period. The amount of unprotected excess deferred taxes is subject to change pending further Internal Revenue Service (IRS) guidance. FERC approval of PSE&G’s Section 205 filing is required to commence any refund to customers and as such, the Annual Transmission Formula Rate update request does not include the impact of the tax refund. This matter is pending. In June 2018, PSE&G filed its 2017 true-up adjustment pertaining to its transmission formula rates in effect for 2017. This resulted in an adjustment of $27 million more than the 2017 originally filed revenues, the impact of which PSE&G had primarily recognized in its Consolidated Statement of Operations for the year ended December 31, 2017. BGSS—In September 2018, the BPU provisionally approved PSE&G’s request to decrease its BGSS rates which will decrease annual BGSS revenues by $26 million. The BGSS rate decreased from approximately 37 cents to 35 cents per therm for residential gas customers effective October 1, 2018. In April 2018, the BPU approved the final BGSS rates which were effective October 1, 2017. Green Program Recovery Charges (GPRC)—In October 2018, the BPU approved PSE&G’s 2017 GPRC cost recovery petition requesting recovery of approximately $58 million and $15 million in electric and gas revenues, respectively, on an annual basis. In June 2018, PSE&G filed its 2018 GPRC cost recovery petition requesting recovery of approximately $65 million and $6 million in electric and gas revenues, respectively, on an annual basis. Remediation Adjustment Charge (RAC)—In October 2018, the BPU approved PSE&G’s filing with respect to its RAC 25 petition allowing recovery of $63 million effective November 1, 2018 related to Manufactured Gas Plant expenditures from August 1, 2016 through July 31, 2017. Energy Strong Program I (ES I) Recovery Filing—In August 2018, the BPU approved recovery of PSE&G’s ES I capital investment petition of an annual revenue requirement increase of $0.6 million and $0.1 million associated with electric and gas investment costs, respectively. This represents the final recovery of electric and gas ES I capital investment costs consistent with the BPU Order of Approval of the Energy Strong Program. In February 2018, the BPU approved recovery of an annual revenue requirement of $8 million associated with electric ES I capital investment costs placed in service from June 1, 2017 through November 30, 2017. Weather Normalization Clause (WNC)—In October 2018, the BPU approved PSE&G’s 2017-2018 WNC petition on a provisional basis allowing a net recovery of $14 million to be collected over the 2018-2019 Winter Period with the new rate effective November 1, 2018. The $14 million net recovery is the result of $9 million of excess revenues from the colder-than-normal 2017-2018 Winter Period offset by $23 million of remaining prior Winter Period undercollection. In April 2018, the BPU gave final approval to PSE&G’s petition to collect $55 million in net deficiency gas revenues as a result of the warmer than normal 2016-2017 Winter Period, which resulted in a deficiency of $31 million, plus a carryover balance of $24 million from the 2015-2016 Winter Period. Gas System Modernization Program I (GSMP I)—In October 2018, PSE&G updated its annual GSMP I cost recovery petition to include GSMP I investments in service as of September 30, 2018. The petition seeks BPU approval to recover in gas base rates an estimated annual revenue increase of $21 million effective January 1, 2019. Societal Benefits Charge—In February 2018, the BPU approved PSE&G’s petition to increase electric rates by approximately $20 million on an annual basis and to decrease gas rates by approximately $0.8 million on an annual basis, in order to recover electric and gas costs incurred through May 31, 2017 under its Energy Efficiency and Renewable Energy and Social Programs. The new rates were effective April 1, 2018.
