As time passed, a number of serious concerns confronted the company. Enron had recently faced several serious operational challenges, namely logistical difficulties in operating a new broadband communications trading unit, and the losses from constructing the Dabhol Power project, a large gas powered power plant in India that had been mired in controversy since the beginning in relation to its high pricing and bribery at the highest level. These were subsequently confirmed in the 2002 Senate investigation. There was also increasing criticism of the company for the role that its subsidiary Enron Energy Services had in the California electricity crisis of 2000–2001.
