PRESS RELEASE

     Quanta Services Closes Additional $72.9 Million Equity Investment by First
Reserve Corporation

HOUSTON, Dec. 23 /PRNewswire-FirstCall/ -- Quanta Services, Inc. (NYSE: PWR -
News) announced today that it has closed on the second equity investment by
First Reserve Fund IX, L.P., a private equity fund managed by First Reserve
Corporation, after successfully amending certain provisions of its agreements
with its lenders and senior secured note holders.

First Reserve Corporation has purchased 2,430,741 shares of Series E Preferred
Stock for $30.00 per share, each share of which, upon shareholder approval, will
be convertible into ten common shares. Proceeds from the sale of shares to First
Reserve will be used initially to pay down outstanding balances under the
company's credit facility. As announced on October 16, 2002, the First Reserve
Fund purchased from Quanta 8,666,666 shares of common stock at $3.00 per share,
and purchased from Aquila, Inc. 3,303,100 shares of Quanta common stock at $3.00
per share and 939,380 shares of Quanta Series A Preferred Stock (convertible
into 4,696,900 shares of common stock) at $3.00 per common share equivalent.

"We are very pleased with First Reserve becoming the largest shareholder in
Quanta and providing growth capital," stated John Colson, chairman and chief
executive officer. "We believe we are well served by having a partner like First
Reserve on our team."

Ben Guill, president of First Reserve, has joined the Company's board of
directors. In addition, First Reserve has the right to nominate two other
members to the Company's board of directors.

First Reserve now owns approximately 37 percent of Quanta's voting stock,
assuming full conversion of the Series E Preferred Stock and Series A Preferred
Stock. A meeting of Quanta's stockholders to approve the convertibility of the
Series E Preferred Stock is scheduled for December 27, 2002. First Reserve has
an agreement with Quanta not to exceed a 37 percent investment without the
consent of Quanta's independent directors.

Quanta also announced today that its Board has approved a voluntary program to
exchange eligible options for restricted stock. Under the program, employees
holding stock options granted under the company's 2001 Stock Incentive Plan with
a per share exercise price equal to or greater than $10.00, have the opportunity
to cancel those options in exchange for restricted shares of the company's
common stock. The restricted stock issued in the exchange will vest over a
three-year period. If all eligible employees accept the offer, approximately 7.8
million outstanding options will be cancelled and approximately 3.2 million
shares of restricted common stock will be issued. In conjunction with the offer,
the number of shares of common stock that may be issued under Quanta's 2001
Stock Incentive Plan will be reduced from 15 percent of common stock outstanding
to 12 percent of common stock outstanding (in each case, assuming full
conversion of the company's Series A and Series E convertible stock).

Based in Houston, Texas and in Greenwich, Connecticut, First Reserve is an
independently owned firm that invests exclusively within the energy and
energy-related sectors of the world economy. It is the leading private equity
firm specializing in the energy industry with $2.6 billion under management.
First Reserve is currently the largest shareholder of Dresser, Inc., Chicago
Bridge & Iron, Pride International, and Superior Energy Services.

INTEROFFICE MEMORANDUM

TO:      All Quanta Services Stock Option Holders
FROM:       John Colson
DATE:       December 23, 2002
SUBJECT:        Stock Option Exchange Program


The Quanta Board of Directors has approved a voluntary program to exchange
eligible stock options for restricted stock. We have been working with the Board
for a while on this program and it reflects our belief that our employees are
our most valuable asset.

We have all watched as our stock price has been carried down by market
conditions. Many of us have stock options valued at four, ten and even fifteen
times the current deflated stock price. If you hold stock options with a per
share exercise price equal to or greater than $10, the stock option exchange
program will give you the opportunity to voluntarily cancel those options in
exchange for restricted shares of Quanta's common stock. The restricted shares
will vest over 3 years.

Your options will be exchanged at a rate or "conversion ratio" determined partly
by the current stock price. We currently estimate this ratio to be one
restricted share for every 2.7 options you exchange.

If you hold eligible options, you will be receiving additional information by
the end of January. The packet will outline the exchange process, conversion
ratio, tax implications and other information relating to the exchange program.
Additionally, we will conduct teleconference calls where you will have the
opportunity to ask questions about the program and the process.

In the meantime, please contact the legal department with any questions you may
have.

Happy Holidays!
