Allegro Development Corp., a leading provider of energy trading and risk management software, recently announced Patriot Coal Corp. will implement its Allegro 8 software. Patriot’s dynamic business demanded automation and further enhancements to the company’s current credit and risk management processes. In addition, Allegro 8 will provide Patriot with a trading and regulatory compliance platform so it will be better prepared to enter into the coal trading arena as corporate objectives and market conditions warrant.
