Item 1.01.              Entry into a Material Definitive Agreement.

As previously reported by Oglethorpe Power Corporation (An Electric Membership Corporation) (“Oglethorpe”), in May 2005 the co-owners of the Alvin W. Vogtle Plant (“Plant Vogtle”), consisting of Oglethorpe, Georgia Power Company (“GPC”), the Municipal Electric Authority of Georgia (“MEAG”) and the City of Dalton, Georgia (“Dalton”, and, collectively with Oglethorpe, GPC and MEAG, the “Plant Vogtle Co-Owners”) executed an agreement regarding the exploration of development of up to two additional nuclear units at the Plant Vogtle site. Oglethorpe has the option to participate in up to 30% of any such additional units at Plant Vogtle.

The Plant Vogtle Co-Owners have recently executed agreements that will govern the rights and obligations of the co-owners of the additional units at Plant Vogtle. These agreements also amend the existing operating agreement governing Plant Vogtle Units 1 and 2 and the existing Amended and Restated Nuclear Managing Board Agreement relating to Plant Vogtle and the Edwin I. Hatch Plant. The effectiveness of these agreements with respect to Oglethorpe is subject to approval by the Rural Utilities Service (“RUS”).

Oglethorpe is currently participating with the Plant Vogtle Co-Owners in the costs of pursuing this new nuclear option, including preparation of applications to the Nuclear Regulatory Commission for the appropriate permits and licenses. Decisions regarding the extent of Oglethorpe’s involvement will be made over the next two years. Oglethorpe may ultimately elect not to participate in any unit that may be constructed, or elect to participate at less than its current 30% participation. To the extent it decides not to participate or reduces its participation, GPC will refund all or a pro rata share of the amounts paid by Oglethorpe, with interest. Prior to making a final election to participate, Oglethorpe must obtain the approvals of its Board of Directors and Members as required by the Amended and Restated Wholesale Power Contracts between Oglethorpe and its Members, as well as the approval of RUS.
