Maritza East I Power Company



Project number:


Business sector:

Notice type:


ESIA disclosed:

31 Mar 2005



Approval date:

26 Jul 2005

Purpose of the Environmental and Social Impact Assessments

The transaction will finance construction of a 2 x 300 MW net lignite-fired power plant (ME1) at Maritsa, Bulgaria. The plant will replace an existing 500 MW of older, less efficient capacity, of which 300 MW have already been phased out and dismantled. 

The project sponsor is AES Corp. AES will own the AES-3C Maritza East I EOOD, a special purpose company established to build, own and operate the plant.  The power from the plant will be sold to NEK, the state-owned utility.

The project represents a major step for private sector participation in the Bulgarian economy as it is one of the country’s largest foreign investment projects to date. A strong “demonstration effect” will be provided by the successful operation of a privatized generator in a liberalized market and the environmental benefits of introducing improved technology that will lead to compliance with EU environmental standards. 

In addition, the investment will also contribute to the advancement of the current restructuring of the sector. This restructuring is a condition to Bulgaria’s EU accession by 2008.
