Exhibit 10.1.6

AMENDMENT TO

THE CONSOLIDATED EDISON

THRIFT SAVINGS PLAN

Taking Into Account:

The Changes Resulting from the 2013 – 2017 Collective Bargaining Contract between the International Brotherhood of Electrical Workers, Local 3 and Consolidated Edison Company Of New York, Inc.

1

Amendment Number 1. The Introduction is amended to add at the end of the Section:

In accordance with the collective bargaining agreement between the International Brotherhood of Electrical Workers, AFL-CIO, and its Local 3 and Consolidated Edison Company of New York, Inc., dated June 30, 2013, through July 1, 2017, the Thrift Savings Plan is being amended to take into account: (i) a new Defined Contribution Pension Formula (“DCPF”); (ii) the entry of certain Local 3 Employees transferring from the Consolidated Edison Retirement Plan into the DCPF; (iii) the increase in the maximum Participating Contributions (contributions subject to an employer matching contribution); and (iv) the increase in the percentage — from 50% to either 75% or 100% — of the employer matching contributions for certain Local 3 Employees.

The newly adopted DCPF will be incorporated into the Thrift Savings Plan document. Many of the provisions, terms, and conditions of the 401(k) Formula and 401(m) Formula will apply to each Participant covered under the DCPF. If there is a difference between whether, or the manner in which, a provision, term, or condition will apply under the DCPF, the difference will be indicated.

The Thrift Savings Plan document serves as a single tax-qualified defined contribution plan under Internal Code Section 401(a), incorporating several formulas.

Amendment Number 2. Article I, Definitions, is amended by adding the following new definitions in their correct alphabetical order:

Compensation Credit Contributions means the contributions made on behalf of a Participant by the Employer under the Defined Contribution Pension Formula.

DCPF Account means the account into which is credited a Participant’s Compensation Credit Contributions and the earnings and losses associated with the DCPF Account.

2

Amendment Number 3. Article I, Definitions, is amended by amending the following definitions to read as follows:

Account Balance is amended by adding at the end of the paragraph the following:

Effective on and after July 2013, Account Balance includes a Participant’s DCPF Account; provided, however, that Account Balance does not include a Participant’s DCPF Account if such DCPF Account is specifically excluded or is otherwise excluded on account of the application of the federal tax law. For example, Account Balance does not include a Participant’s DCPF Account for purposes of nondiscrimination testing under the ADP – 401(k) testing or the ACP – 401(m) testing. Account Balance does include a Participant’s DCPF Account for purposes of the investment management of a Participant’s Account Balance.

Employer Matching Contribution is amended by adding at the end of the paragraph the following:

Effective on and after July 2013, Employer Matching Contribution does not include an Employer Compensation Credit Contribution.

Amendment Number 4. Article II, Eligibility and Participation, Section 2.01, Eligibility, is amended by adding a Subsection (d), to read as follows:

(d) Only certain Employees, as more fully described in Article XV, are eligible to participate in the Defined Contribution Pension Formula. Article II does not apply or govern the terms or conditions for eligibility under or participation in the Defined Contribution Pension Formula.

Amendment Number 5. A new Article XV, Defined Contribution Pension Formula, is added after Article XIV, to read as follows:

Article XV

Defined Contribution Pension Formula

15.01 Defined Contribution Pension Formula – Establishment

a. Effective as of July 1, 2013, the Company has established the Defined Contribution Pension Formula (“DCPF”) which is a separate defined contribution pension formula negotiated and agreed upon by Local 3 and CECONY.

b. Except as otherwise provided in this Article XV, the provisions in the Thrift Savings Plan that would apply to a defined contribution pension formula, such as the sections setting forth Plan Administration apply to the DCPF and are not repeated in this Article XV.

15.02 Participation in the DCPF for a Local 3 Employee – Pension Choice

a. Each Local 3 Employee who is hired on or after June 30, 2013, will have a period of time to make a Pension Choice election to be covered under the cash balance pension formula in the Retirement Plan or to be covered under this DCPF.

c. Entry dates are the first day of each calendar quarter.

d. Whether such Local 3 Employee elects to participate or is deemed to have elected to participate, his or her Pension Choice is irrevocable.

15.03 Participation Rules for a Local 3 Employee Transferring From the Retirement Plan

a. An individual who: (i) is a Local 3 Employee; (ii) covered under the cash balance pension formula in the Retirement Plan; and (iii) has elected to transfer out of the cash balance pension formula in the Retirement Plan and into the DCPF, will become covered under the DCPF as soon as practicable following the date that his or her Pension Choice election form has been properly submitted.

b. If such Local 3 Employee makes and properly submits his or her Pension Choice election in the first or second month of a calendar quarter, he or she will begin participation on the first day of the next calendar quarter.

15.04 Defined Contribution Pension Formula

a. The Company will contribute at the end of each calendar quarter (end of March, June, September, and December), or as soon as administratively practicable, a Compensation Credit on behalf of each Participant covered under the DCPF in accordance with the following formula:

a. Basic straight-time compensation is determined based on the Participant’s rate of pay in the last pay period in the Calendar quarter. Sunday premium pay, night shift, and midnight shift differential premium pay are based on amounts actually earned during the preceding calendar quarter.

6

b. A Participant whose termination of employment occurs in the first or second month of a calendar quarter shall receive an allocation for such calendar quarter. He or she will receive an allocation equal to a pro rata quarterly allocation based on age, years of Accredited Service, and the Compensation he or she received in such calendar quarter at his or her termination of employment. The Participant will receive his or her applicable percentage times her or his Compensation as of the date of termination of employment. Additionally, if the Participant has exceeded the Social Security Taxable Wage Base, he or she will receive an additional 4% allocation on the Compensation in the calendar quarter that has exceeded the Social Security Taxable Wage Base.

c. For any period of an authorized, unpaid leave of absence for which the Participant receives Accredited Service (up to but not to exceed six months), the Participant shall receive Compensation Credits to his or her DCPF Account. The Compensation Credits shall be determined on the assumption that the Participant continued to receive during the leave period his or her Compensation (excluding any Sunday premium pay and night shift and midnight shift differential premium pay during the calendar quarter ) based on the rate of pay in effect for such Participant immediately prior to such leave of absence.

15.05 Participant Investment Directions and Choices for the DCPF Account

A Participant’s entire DCPF Account, whether or not vested, is available for Participant investment direction.

d. Each Participant is fully responsible for the investment directions and asset allocations of his or her DCPF Account. The Company is not responsible for how the DCPF Account is invested or for any or all losses resulting from the investment decisions made by the Participant.
