On March 13, 2003, Governor Gray Davis asked the Energy Commission and the Public Utilities Commission to investigate the price "spikes" for natural gas and asked the Energy Commission to investigate gasoline prices. The initial two reports were sent to Governor Davis on March 28, 2003. The Governor also requested monthly updates of the situation.
