Re: Revision to 2008 Year in Review

The MSA published its 2008 Year in Review on March 19, 2009. It has come to our attention that there is an error that affects values in Section 1.2.1 along with Table v and Figure iv in Section 1.2.5.  These figures did not take into account the $10/MWh fuel cost for a coal plant as stated in Table i.  The values in these sections have been corrected.  The revised version of the 2008 Year in Review is now posted to our web site.

We apologize for the error and any inconvenience that it may have caused.

Regards,

“Original Signed”
