Hickory Run Energy Center, Pennsylvania
A
power plant often provides a region
with more than just electricity. A large
generation facility can also be an economic
engine for an entire community.
The Hickory Run Energy Center, a
1,000-MW natural gas-fired combined cycle
power plant, has proven to be just that
for Lawrence County in Pennsylvania.
The station includes two Siemens SGT6-8000H gas turbines,
two John Cockerill Energy heat recovery steam generators
(HRSGs), and one Siemens SST6-5000 steam turbine.
Tyr Energy LLC is the asset manager for the plant, located
in New Castle, about 45 miles northwest of Pittsburgh. The
facility has been a driving force behind more than $1 billion
in capital investment projects in the county over the past few
years, providing even more of a boost to the local economy
after coming online in May 2020.
Hickory Run is contributing to a rebound in manufacturing in
the New Castle area, a region with a rich industrial history, starting
with iron and brick works in the mid-1800s and continuing for
many years as a hub for iron and steel. The area for a time was
known as the " Fireworks Capital of America, " during a period
when more fireworks were produced in Lawrence County than
anywhere else in the U.S., and the industry remains important
to the region. New Castle was known as the " Hot Dog Capital
of the World, " owing to the popularity of the chili dogs produced
by Greek immigrants who settled in the area.
The area today is known as a regional banking hub, and its

location near several major highways-along with the power
provided by Hickory Run-is supporting a manufacturing renaissance.
The plant's importance to the region, along with the
perseverance of its builders in overcoming construction obstacles,
has led POWER to recognize it with a Top Plant Award in
the natural gas-fired category.
The plant is owned and operated by Hickory Run Holdings
LLC, a joint venture of Japan-based ITOCHU Corp.'s whollyowned
subsidiary Tyr Energy (50%), Kansai Electric Power
(30%), and Siemens Financial Services (20%). Kiewit Power
Constructors Co. (Kiewit) was awarded the engineering, procurement,
and construction contract in 2017. Siemens Energy
was contracted in November 2017 to supply the key components
of the plant, including the turbines and generators. ■
Prime Termoflores, Colombia
C
olombia's power profile is heavily
dependent on hydropower,
but despite sectoral reforms instituted
in 1992, when an especially severe
El Niño event steeped the country
in a chronic power crisis, the wholesale
market continues to exhibit highly volatile
spot price outcomes given the unpredictability
of hydro availability. To have any edge in the market,
the country's gas generators-which must also compete for
about 30% of domestically produced gas despite the sporadic
use of gas power-must achieve exemplary performance.
That has required efficiency achievements, however small
they may be.
At Prime Termoflores, a two-unit 610-MW combined cycle
gas turbine power plant in Barranquilla, a major industrial city
in the northern Caribbean Coast region, the stakes are even
greater, given the region's rapid urban growth and economic
development. Operator Prime Termoflores redesigned the generator
and lube oil cooling systems of the 450-MW Flores IV
unit in a set of projects that involved replacing three cooling
fans of the generator glycol system and two fans of the lubrication
oil system. The system now feeds circulating water
directly to the generator coolers instead of glycol and supplies
the new Alfa Laval plate heat exchanger for the lube oil system.
Combined, the two projects led to the dismantling of five
motors, resulting in a power savings of 85 kW. But they also
saved another 75 kW after improving the operating point of the

condenser cooling system pump.
In all, the solutions also turned out to be money savers.
Prime Termoflores saved an estimated $890,000 with the solution
when compared to having to replace the fan coolers.
Crucially, they also avoided an extended outage, which would
have been detrimental to the company's revenue. Plant workers
spent two months in the middle of the pandemic building
pipes and readying structural components. Another project
involved replacing the unit's two 150-kW water-cooled instrument
air compressors with a pair of 56-kW air-cooled compressors.
The solution resulted in an additional power savings
of 188 kW. ■
