About MMC Energy, Inc.:

MMC, based in New York and San Diego, acquires and actively manages electricity
generating and energy infrastructure-related assets in the United States. MMC is
traded on the NASDAQ Global Market in the United States.

MMC'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."

MMC creates long-term value for its stockholders through disciplined asset
acquisitions and hands-on post-acquisition asset management. MMC 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, MMC has acquired three electricity generating assets in California,
totaling 110 MW of capacity. MMC is 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 44.5 MW
facilities at each site.
