Leading Energy Efficiency Appraisal Firm Provides Highly Favorable Assessment of Green St. Energy's Tehachapi Land to Be Utilized as a Wind Farm

The FirstLook Report also estimated that the power capacity factor at the location, a common assessment tool for wind farm viability, is 40%.

This rating is considered Excellent by industry standards. Many existing US wind farms have been financed and are being operated successfully at 28% to 30% capacity factors; thus, the Green St. Energy Tehachapi site rating by 3TIER indicates a wind power capacity that is approximately 33% greater than average standards for finance-able wind farms in the US market. The 40% power capacity rating is an annual average power capacity based on a turbine-type that is typical for the property.

"We are excited that a leading energy consulting firm has determined that the wind speeds at the land are so strong," said Tony Cataldo, Green St. Energy's Chairman and CEO. "This has important implications for our ability to attract developmental partners and financing for the project. We believe there is significant upside potential for the Property and are confident that the infrastructure in place in Tehachapi, the long history of wind project success in the Tehachapi region and highly attractive characteristics of this land enhances our ability to generate significant revenue from this Project."

The Company also announced today that it has changed its name from MWave, Inc. to Green St. Energy to better reflect its current business and operations.
