TSX : AXY

VANCOUVER, Feb. 27, 2012 /PRNewswire/ - Alterra Power Corp. (TSX: AXY) announces that the Dokie General Partnership ("DGP") has exercised a one-time right in its energy purchase agreement with B.C. Hydro to increase its firm energy allotment by 10%.

Because the firm energy allotment is the highest priced tranche of the energy purchase agreement, the increase in power priced under that allotment is expected to result in an average annualized net revenue increase from DGP of 1.2%.

The increase is effective May 1, 2012. It is subject to review and renewal every five years for additional five year periods.

In addition, on February 16, 2012, the Final Completion certificate for Dokie was issued to Mortenson Canada Corporation, the major contractor, formally marking completion of all construction activities.
