Midwest Renewable Energy Tracking System (M-RETS) Issues Certificates.

APX Market System Delivers Certification, Tracking and Trading Capabilities On-Time

SANTA CLARA, Calif. -- APX, Inc., the leading infrastructure provider for North American environmental and energy markets, is pleased to announce that the Midwest Renewable Energy Tracking System (M-RETS) is now issuing Renewable Energy Certificates (RECs) and has completed all user acceptance testing.

The first RECs under M-RETS were issued on October 15, in keeping with the schedule previously announced. A web-based hosted system, APX technology creates, tracks and enables trading of RECs through a unique, traceable digital certificate issued for every MWh of renewable energy generated by generating units registered with M-RETS or imported into M-RETS. Registration continues to be open for power generators, utilities, marketers and qualified reporting entities wishing to participate in the M-RETS market, subject to verification and approval of the M-RETS administrator. The geographic scope of the environmental market served by M-RETS includes Wisconsin, Minnesota, Iowa, South Dakota, North Dakota, and the province of Manitoba.

"We are pleased with the progress Wisconsin utilities have made in meeting the state's renewable energy standards," said Public Service Commission of Wisconsin Commissioner Mark Meyer. "M-RETS is providing the needed system to track renewable credits and is helping Wisconsin and the Midwest set an example for other states to follow. We look forward to this continued partnership and meeting the nation's renewable energy goals."

"Minnesota continues to be highly supportive of M-RETS as a market-based program that will help us meet our goals as stated in the Renewable Energy Standard," said Edward Garvey, Deputy Commissioner of Energy and Telecommunications for the Minnesota Department of Commerce. "M-RETS also gives utilities greater flexibility in meeting renewable energy requirements while providing greater transparency and assurance to consumers that renewable power is produced and delivered to the regional electric system."

Similar to other market-oriented systems, M-RETS enables renewable energy credit tracking and trading, helping to keep costs of developing renewable energy down and encouraging renewable energy generation. It will also provide the states an ability to further reduce their reliance on fossil fuels and will help reduce greenhouse gas emissions. For more information on the program visit www.m-rets.com.

We are pleased to partner with leading organizations in the Midwest region to help them drive the expansion of both the M-RETS system and renewable energy generation."
