                   QUANTA SERVICES ANNOUNCES EQUITY INVESTMENT
                          BY FIRST RESERVE CORPORATION


     HOUSTON - October 16, 2002 - Quanta Services, Inc. (NYSE: PWR) announced
today that a private equity fund managed by First Reserve Corporation has
committed to invest up to $135 million in the Company. Quanta today agreed to
First Reserve Fund IX, L.P.'s purchase of 8,666,666 newly issued Quanta common
shares at $3.00 per share. The First Reserve fund also purchased 3,303,100
Quanta common shares at $3.00 per share and 939,380 Quanta Series A preferred
shares (convertible into 4,696,900 common shares) at $3.00 per common share
equivalent from Aquila, Inc. As a result, Aquila's ownership is reduced to
approximately 14 percent. The combined value of these transactions is
approximately $49.9 million.

     "We are very pleased with First Reserve's desire to become the largest
shareholder of Quanta and provide growth capital at a significant premium to our
recent stock price," stated John Colson, chairman and chief executive officer.
"When First Reserve approached us with their proposal, they understood and
believed in our mission to be the best specialty contractor within the markets
we serve. As we calibrate our company to better meet the challenges facing our
customers and the economy in general, we are extremely well served by having a
partner like First Reserve on our team."

     The Company also agreed to allow the First Reserve fund to purchase
2,430,741 Quanta preferred shares in a second closing, each share of which will,
upon shareholder approval, be convertible into ten common shares. The price per
common share equivalent will not be less than $3.00 nor more than $3.50,
depending upon the average closing price of Quanta's common shares for a period
prior to the second closing. The second closing is conditioned on Quanta's
negotiation of certain amendments with its lenders and senior secured note
holders allowing the Company greater flexibility to grow its business. The
closing is also subject to clearance under antitrust laws.




     Ben Guill, president of First Reserve, will join the Company's board of
directors; and, after the second closing, First Reserve may designate two
additional directors to the board.

     Upon closing of the second investment, First Reserve would own
approximately 37 percent of Quanta's voting stock, assuming full conversion of
the preferred shares. First Reserve has an agreement with Quanta not to exceed a
37 percent investment without the consent of Quanta's independent directors.

     In exchange for consideration from the Company of approximately $2.2
million, the Company obtained from Aquila certain waivers of anti-dilution
rights, preemptive rights and limitations on the number of directors on Quanta's
board.

       Quanta Services, Inc. is a leading provider of specialized contracting
services, delivering end-to-end network solutions for electric power, gas,
