ON THE COVER
The 750-MW Trianel Coal Power Plant in Lünen, Germany, equipped with an SST5-6000
steam turbine and a SGen5-3000W generator from Siemens, boasts an efficiency of nearly
46% and is one of this year's coal-fired Top Plant Award winners. Courtesy: Siemens
COVER STORY: COAL TOP PLANTS
22 Camden Power Station, Mpumalanga Province, South Africa
Described as " the largest return to service project in the world, " the recommissioned
Camden Power Station saved almost $9.5 billion compared to the cost of new power
stations of equal size. It also provided electricity for a nation with precarious energy
security much sooner than a new-build project.
24 Hitachinaka Thermal Power Station Unit 2, Tokai, Ibaraki Prefecture, Japan
Industry-leading efficiency for a coal-fired plant would likely have made this a Top
Plant Award winner in any year. Getting the unit built on time-despite massive earthquake
and tsunami damage to the site during construction-solidified the case.
28 Mundra Thermal Power Plant, Mundra, Gujarat, India
This supercritical plant is frugal with fuel, water, and site acreage even though it's the
world's largest single-location private sector thermal power station. It has also set an
Indian power sector generation record.
32 Sesa Sterlite Captive Power Plant, Jharsuguda, Odisha, India
This captive power plant, which serves the grid and an adjacent power-hungry aluminum
smelter, has some of the most advanced environmental controls in India and
is the first coal-fired unit in the country to employ high-concentration slurry disposal
of dry and bottom ash.
34 Trianel Coal Power Plant Lünen, North Rhine-Westphalia, Germany
Even as Germany continues its transition to higher levels of renewable generation,
reliable baseload capacity is needed, and this plant, arguably the cleanest and most
efficient hard coal-fired plant in Europe, is helping to fill that role.
SPECIAL REPORT: OPERATIONS & MAINTENANCE
36 Prepare Your Coal Plant for Cold Weather Operations
Following the North American Electric Reliability Corp. winterization guidelines is a
good start to cold weather preparations, but each coal power plant needs a site-specific
plan that ensures everything from fuel supply availability to personnel safety.
40 Prepare Your Gas Plant for Cold Weather Operations
The February 2011 record cold weather in the U.S. took many gas-fired plants in
otherwise mild regions by surprise, resulting in derates for hundreds of units. Here's
a look at a number of common failure modes, proactive steps for all plants, and a
guide to prioritizing upgrades.
44 Prepare Your Nuclear Plant for Cold Weather Operations
U.S. nuclear plants performed well during last winter's polar vortex, and although
Nuclear Regulatory Commission documents cover the winterization of nuclear
plants, following such guidance may not be sufficient on its own. Two plants share
their customized approaches.
47 Prepare Your Renewable Plant for Cold Weather Operations
The relatively recent widespread deployment of wind turbines and utility-scale solar
generation has resulted in some cold lessons learned when equipment wasn't up to
frigid weather spec. We look at the latest tools for making wind, solar, and even small
hydro installations winter-ready.
