GenOn Energy Holdings

[4] Mirant operated 13 plants in the states of California, Georgia, Maine, Maryland, Massachusetts, Michigan, New York, and Virginia and has the capacity to generate approximately 10,300 MW of electricity.

In the years to come, other acquisitions followed, notably the acquisition of a British distribution utility - South Western Electricity Board later renamed SWEB (now known as Western Power Distribution); a controlling interest in Hong Kong based Consolidated Electric Power Asia (CEPA), a stake in a German utility BEWAG, controlling interest in Empresa Electrica del Norte Grande, S. A.

(EDELNOR) in Chile, and a hydroelectric generating facility in Argentina known as Hydroelectrica Alicura; giving it worldwide business interests in the Caribbean, Asian, South American and European energy markets.

That same year SEI was renamed Southern Energy, in keeping with the broader theme of the products and markets that it pursued.

[10] On November 10, 2004, a group of Chesapeake Climate Action Network activists, students, farmers, and religious officials held a protest against the coal-fired Dickerson Power Plant in Montgomery County, Maryland.

[11] Mirant, which owns and operates two power plants in the Hudson Valley Region of New York State, failed to pay its property taxes in a dispute with tax authorities, claiming over-assessments by the Towns of Stony Point and Haverstraw New York, as well as the North Rockland School District.

This case, which has caused local residents to themselves file bankruptcy, cost the average taxpayer over $2000 in increased property taxes.

Following proceedings in state court, a settlement was reached between Mirant and the towns in December 2006, with taxes based on lower assessed values of the two power plants.
