JP Morgan chief executive Jamie Dimon has been trying to improve the image of the bank
JP Morgan's energy unit has agreed to pay $410m (£268m) to settle charges from the top US energy regulator that it manipulated energy markets.
The Federal Energy Regulatory Commission (FERC) agency alleged JPMorgan's trading practices drove up prices for electricity, mainly in California and the Midwest.
The fine is the second largest penalty in FERC history.
The bank did not admit any wrongdoing as part of the settlement.
JPMorgan spokesman Brian Marchiony said the settlement would "not have a material impact on our earnings" because the bank had previously set aside reserves for the case.
Under the deal, the bank must also make annual reports to the commission for three years detailing its power business in the United States.
JPMorgan has already sold the rights to buy the gas and sell the power from its California plants.
