PJM Passes Tough Systems Audit

LCG, Oct. 16, 2001--PJM Interconnection, the regional transmission organization formed by members of the Pennsylvania-New Jersey-Maryland Power Pool, said yesterday it had passed with flying colors a tough audit of its systems conducted by PricewaterhouseCoopers.

PJM said the audit indicated that its market settlement processes have achieved a comprehensive set of control objectives designed to protect the integrity of market settlement data, assuring its 200 members that the information and activities they rely on from PJM are operated in a well controlled and risk-managed environment.

"We are pleased with the results of this audit and proud to be able to demonstrate to our members that our control and business practices meet stringent guidelines," said Phillip G. Harris, PJM chief executive.

PJM pointed out that it had voluntarily submitted to the Statement on Auditing Standards 70 type II audit, which encompassed all control objectives related to the PJM market settlement process as well as its Internet tools -- the information technology infrastructure that supports the multiple PJM markets.

According to PricewaterhouseCooper's findings, the controls that were tested were operating with sufficient effectiveness to provide reasonable assurance that the specified control objectives were achieved during the time period covered by the audit, PJM said.

PJM claims (with justification) to be the country's only fully functioning RTO, operating the world's largest competitive wholesale electricity market and one of North America's largest power grids.
