WASHINGTON, Oct 24 (Reuters) - U.S. Energy Secretary

Chris Wright on Friday issued an order that allows part of

Talen's oil-fired Wagner power plant in Maryland to run

above limits through the end of 2025, saying it would boost the

reliability of the grid.

President Donald Trump declared an "energy emergency" on the

first day of his second term. But he has taken a slew of actions

to slash tax breaks and other support for renewable energy and

has favored fossil fuel use at aging power plants.

In July, Wright granted a request by the PJM Interconnection

regional grid manager to allow the nearly 400-megawatt unit to

run above limits. It was one of several units at Wagner that had

been set to shut permanently in May before federal energy

regulators approved keeping it open until 2029.

The Energy Department said on Friday the "growing

resource adequacy concern" that PJM cited in their July request

"still exists today."

Wright has also ordered a Michigan

coal plant

and a Pennsylvania plant that runs on natural gas or oil to

stay open.
