 Exhibit 10.21 

SEVERANCE AGREEMENT 
 AND
GENERAL RELEASE OF ALL 
 CLAIMS 

This Severance Agreement and Release of All Claims (the “Agreement”) is made and entered into by and between Eric B. Brown
(hereinafter referred to as the “Employee”) and Quanta Services, Inc., a Delaware corporation, (hereinafter collectively referred to as the “Company”). 

The purpose of this Agreement is to arrange a settlement of the Employee’s employment with the Company that is satisfactory both to the
Company and to the Employee. By signing this Agreement, the Company and the Employee agree as follows: 
  

	1.	Termination of Employment. The Employee and the Company are entering into this Agreement as a way of amicably concluding the employment relationship between them on September 15, 2014
(“Separation Date”), and of resolving voluntarily any dispute or potential dispute or claim that the Employee has or might have with the Company, whether known or unknown by the Employee at this time. This Agreement is not and should not
be construed as an allegation by Employee, or as an admission on the part of the Company, that the Company has acted unlawfully or violated any state or federal law or regulation. The Company, including its parent companies, affiliates, associated
companies, and subsidiaries, specifically disclaim any liability to the Employee or any other person for any alleged violation of rights or for any alleged violation of any order, law, statute, duty, policy or contract. 


 

	2.	Severance Benefits. As consideration for the Employee agreeing to release the Company from all claims and liabilities that are described in Paragraph 6 herein and subject to the provisions of Paragraph 10
herein, the Company will pay Employee the following as severance benefits (the “Severance Benefits”): 

  

	 	a.	a lump sum, equal to nine (9) months of Employee’s base salary, in the amount of Two Hundred Ninety Two Thousand Five Hundred Dollars ($292,500), less applicable taxes and authorized withholdings, with such
amount to be paid within ten (10) days after the expiration of the period for Employee to revoke his acceptance to this Agreement under Paragraph 9, but in no event later than November 15, 2014; and 


 

	 	b.	 a lump sum amount equal to Employee’s 2014 annual cash bonus, pro rated from January 1, 2014 through the Separation Date. The amount of the
bonus will be established on or around February 28, 2015, in accordance with the Company’s customary practice for setting bonus amounts, and will be paid to Employee in a lump sum, less applicable taxes and authorized withholdings, within
ten (10) days after the date the bonus amount is set, but in no event later than March 15, 2015. 










	 	
For purposes of pro-rating the bonus, Employee’s annual bonus amount shall be multiplied by 70.7% to pro-rate the bonus for the period of January 1, 2014 through the Separation Date.


 Each payment payable under this Agreement is intended to be exempt from or compliant with Section 409A of Internal
Revenue Code and constitutes a separate payment for purposes of Section 409A of the Internal Revenue Code. The timing of payment pursuant to this Paragraph shall be determined as established herein and Employee may not designate the time of
payment of any of the Severance Benefits. 
  

	3.	Entire Consideration. The Employee agrees that the Severance Benefits set forth in Paragraph 2, herein, constitute the entire amount of consideration provided to him under this Agreement. The Employee
further agrees that he will make no claim for any additional or other severance benefits or payments and that he will not seek any further compensation for any other claimed damage, costs, severance, income or attorneys’ fees.


  

	4.	Nondisclosure Agreement. Without the express written agreement of the Company’s Chief Executive Officer, or unless required to do so by law, the Employee agrees never to disclose the existence, facts,
terms, or amounts paid under this Agreement, nor the substance of the negotiations leading to this Agreement, to any person or entity, other than to his personal counsel or attorney, personal accountants, or personal tax preparer, any such
disclosure to such persons to be made only if the relevant person must have such information for the performance of his or her responsibilities. To the extent required by law or applicable regulation, Employee may also disclose the provisions of
this Agreement to the appropriate taxing or regulatory authorities. If Employee receives a subpoena or other request for documents in a legal proceeding calling for production of this Agreement, Employee will immediately notify the Employer (to the
attention of the Company’s General Counsel or Chief Executive Officer) of such subpoena or request, so that the Company may determine whether to assert objections or seek legal relief to prevent disclosure of this Agreement. 


 

	5.	 The Employee’s Release Of All Claims Including Age Discrimination In Employment Act Claims. In consideration of the Severance
Benefits, the Employee, for himself, his heirs, executors, administrators, successors and assigns, does fully and forever release and discharge the Company, its parent companies, affiliates, associated companies, and subsidiaries, their respective
associated companies and subsidiaries, all of their respective present and former officers, directors, supervisors, managers, employees, stockholders, agents, attorneys and representatives, and the successors and assigns of such persons and entities
(collectively, the “Released Parties”), from all actions, lawsuits, grievances, complaints, liens, demands, obligations, damages, liabilities, and claims of any nature whatsoever, know or unknown, that the Employee had, now has, or may
hereafter claim to have against the Released Parties from the beginning of time through the date the Employee executes this Agreement. The release provided herein specifically includes, but is not limited to, all claims arising under any federal,
state or local fair employment practice laws, and any other employee relations statute, executive order, law and ordinance, including, but not limited to, Title VII of the Civil Rights Acts of 1964, as amended; the Civil Rights Acts of 1866, 1870,
and 1871, as

amended; the Civil Rights Act of 1991, as amended; the Age Discrimination in Employment Act of 1967, as amended; the Older Workers Benefit Protection Act, as amended; the Americans With
Disabilities Act of 1990, as amended; the Family and Medical Leave Act, as amended; the Equal Pay Act, as amended; the Fair Labor Standards Act, as amended; the Worker Adjustment and Retraining Notification Act of 1988, as amended; the Employee
Retirement Income Security Act of 1974, as amended; Section 806 of the Sarbanes-Oxley Act of 2002 (18 U.S.C. §1514A, et seq.); the Rehabilitation Act of 1973 (29 U.S.C. Section 791 et seq.); the Occupational Safety and
Health Act (29 U.S.C. § 651, et seq.); the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (COBRA); the Texas Labor Code, as amended; the Texas Administrative Code, as amended; the Texas Commission on Human
Rights Act, as amended; any local human rights law; and any tort or contract cause of action or theory. 

 The Employee
expressly represents and agrees that he has been advised that, by entering into this Agreement, he is waiving all claims that he may have against the Company arising under the Age Discrimination in Employment Act of 1967, as amended, which have
arisen on or before the date of execution of this Agreement. 
  

	6.	Covenants Concerning Claims/Limitations on Scope of Agreement. The Employee agrees that he will not file any complaints, claims or actions against the Released Parties with any court regarding any matters
or claims that arose prior to the Employee’s execution of this Agreement. If any court assumes jurisdiction on behalf of the Employee of any complaint, claim or action against the Company, he will direct that court to withdraw from or dismiss
with prejudice the matter. 

 Notwithstanding the preceding provision or any other provision of the Agreement, Employee’s
agreement to the provisions under Paragraph 5, or any other section of this Agreement, is not intended to prohibit Employee from bringing an action to challenge the validity of the release of claims under the Age Discrimination in Employment Act, as
amended, or the Older Worker’s Benefit Protection Act, as amended. The Employee further understands and agrees that if he or someone acting on his behalf files, or causes to be filed, any such claim, charge, complaint, or action against the
Released Parties, he expressly waives any right to recover any damages or other relief, whatsoever, from the Released Parties, including costs and attorneys’ fees. 

Nothing in this Agreement is intended to, or will, interfere with Employee’s right to file a charge with, provide information to,
cooperate with, or participate in an investigation or administrative proceeding conducted by the Equal Employment Opportunity Commission or state fair employment practices agency, or by any other federal or state regulatory or law enforcement agency
or commission. However, by executing this Agreement, Employee hereby waives the right to recover, and agrees not to seek any damages, remedies or other relief for himself personally in any proceeding he may bring before such agency or in any
proceeding brought by such agency, or any other person, on his behalf. This Agreement is also not intended to apply to claims for accrued benefits (other than severance-type benefits) under any benefit plan of the Released Parties pursuant to the
terms of any such plan.

 Employee understands that he is not releasing rights under this Agreement that cannot be waived
as a matter of law, that any claims that cannot be lawfully waived are excluded from this Agreement, and that by executing this Agreement he is not waiving any such claims. Likewise, Employee is not releasing any rights or claims that may arise
after the date on which he signs this Agreement including but not limited to rights under the Indemnity Agreement dated February 20, 2014. In addition, while this Agreement requires Employee to waive any and all claims against the Released
Parties arising under workers’ compensation laws (e.g., claims of retaliation for filing a workers’ compensation claim), it is not intended to prohibit Employee from filing in good faith for and from receiving any workers’
compensation benefits from Released Parties’ workers’ compensation carrier for compensable injuries incurred during his employment. Accordingly, pursuit of any such workers’ compensation benefits with Released Parties’
workers’ compensation carrier or third-party administrator will not be considered a violation of this Agreement.

	 	a.	In return for and in consideration of his execution, delivery and performance of this Agreement, the Company is providing to the Employee the Severance Benefits.

option and discretion expedite the processing of some or all of the Severance Benefits, subject to the revocation period set forth in Paragraph 9.
