Regulatory investigations

In analyzing PG&E’s Gas Transmission & Storage (GT&S) business’ 1997-2010 operations & maintenance expenses and capital expenditures, Brattle experts found that its actual spending exceeded the adopted amounts that were provided for in revenue requirements and rates. We also found that GT&S’ profitability during this time was largely due to its success in selling at-risk storage services and not due to alleged spending reductions.
