financiers to a restructuring of the project's debt, satisfactory resolution
of regulatory issues and approvals, rulings on tax and stamp duty obligations,
as well as approvals from the investors in Horizon Energy and the creditors
committee of NRG Energy.

The brown coal-fired plant is the largest generator in Victoria,
Australia, accounting for about 24 percent of the state's electricity

business operations an electric and natural gas utility, natural gas pipeline
systems and independent power generation.
