Table: Aftershocks

Troubled power generators and traders face more turmoil:


Cautious trading partners will demand more collateral, and investors will remain skittish, even as players slash spending and unload assets. Expect a shakeout of trading operations as some scale back and others sell.


State and federal regulators will more aggressively monitor and enforce rules amid new efforts to close loopholes that allow market manipulation.


The industry's earnings prospects will be hampered, plans for new power plants will be canceled or postponed, and deregulation could be stalled for years.
