MMC Energy, Inc. Annonces Turbine Purchase

MMC Energy, Inc. (Nasdaq:MMCE) announced that on May 15, 2008, it agreed to
purchase one LM-6000 PC Sprint(r) natural gas-fired turbine from GE Energy, to
be used in its Escondido Energy Upgrade Project, a 50 MW natural gas-fired power
plant in Escondido, San Diego County, California.

The total purchase price for the turbine is approximately $15.3 million, to be
paid in several installments through December 31, 2008. The turbine is the
primary equipment to be used in the Energy Upgrade Project, and will allow the
Company to increase its capacity at the Escondido site, currently 44MW, as well
as to greatly improve its efficiency and reduce its emissions generated per
MW-hour.

In January 2008, the Escondido City Council approved the Company's application
for a conditional use permit to construct its Escondido Project. Upon receipt of
an air permit from the San Diego Air Pollution Control District, the permitting
process will be complete for the Escondido Project.

"We are pleased to announce this significant progress and further commitment to
completing the Escondido Energy Upgrade Project by Summer 2009," said Mike
Hamilton, the Company's CEO.

About MMC Energy, Inc.:

The Company acquires and actively manages electricity generating and energy
infrastructure-related assets in the United States. The Company is traded on the
NASDAQ Global Market in the United States. The Company's mission is to acquire,
directly or through joint ventures, a portfolio of small to mid-size natural gas
fueled electricity generating assets, generally below 250 megawatts or "MW."

The Company creates long-term value for its stockholders through disciplined
asset acquisitions and hands-on post-acquisition asset management. The Company
actively invests in electricity assets that provide essential services to key
transmission-constrained markets such as California, where regulatory capacity
requirements and a lack of local electricity supplies make peak electricity
generation facilities valuable.

To date, the Company has acquired three electricity generating assets in
California, totaling 110 MW of capacity. The Company is currently in the process
of upgrading two of these assets, the 100 MW MMC Chula Vista Energy Upgrade
Project and the 50 MW MMC Escondido Upgrade, both located in San Diego County,
California, replacing the existing 44 MW facilities at each site.
