                     QUANTA SETS MAY 23, 2002 ANNUAL MEETING

                      WILL MAIL DEFINITIVE PROXY MATERIALS

HOUSTON - APRIL 15, 2002 - Quanta Services, Inc. (NYSE: PWR), a leading provider
of specialized contracting services to the electric power, gas,
telecommunications and cable television industries, today announced that it has
filed a definitive proxy statement with the Securities and Exchange Commission
and has set its annual meeting for Thursday, May 23, 2002. The meeting will be
held at 9:00 local time at the Houston St. Regis Hotel.

Quanta will mail its definitive proxy statement this week. The mailing will
include a white proxy card which stockholders will be asked to sign and in
support of Quanta's current Board of Directors. Stockholders of record as of the
close of business on Monday, April 29, 2002 will be eligible to vote at the
meeting. At the meeting, Aquila, Inc. (NYSE: ILA) is seeking to remove all of
Quanta's existing Directors and replace them with its nominees in order to
facilitate the consolidation of Quanta's earnings into Aquila's financial
statements.

John R. Colson, Quanta's chief executive officer, said, "It is important that
all stockholders exercise their right to vote at this critical annual meeting.
We encourage them to sign and return the white proxy cards as soon as they
receive them."

Colson continued, "Contrary to what Aquila has said in order to meet its own
objectives, Quanta is performing well, delivering strong financial and
operational results relative to its peers and has excellent long-term growth
prospects. In 2001, Quanta generated record revenues of $2.01 billion and record
cash flow from operations of $210 million, alongside stronger EPS performance
and better EBIT and EBITDA margins than its competitors.

Members of Quanta's Board continue to make significant contributions to Quanta's
business and two of the Company's Directors were responsible for almost 35% of
Quanta's 2001 revenues. Investors should note that seven of Aquila's nominees do
not own any Quanta stock and six are executives of Aquila or an entity it
controls."

Colson concluded, "As Aquila has said in the past, its nominees to Quanta's
Board are pledged to serve Aquila's interests if elected. Quanta's Board will
continue to vigorously oppose Aquila's efforts to take control of Quanta to
fulfill its own accounting imperatives, without providing appropriate benefits
or protections to our other stockholders."
