COMMERCIAL & INDUSTRIAL GENERATION AWARD
Collaboration and Innovation Produce a Powerful Microgrid Solution 34
Caterpillar needed a power solution for its field trial complex in Arizona, and
the company turned to its own microgrid technology. The integrated solar and
generator set system has been honored with POWER's inaugural Commercial
and Industrial Generation Award.

Microgrids: An Old Concept Could Be New Again
42
Microgrids-self-contained systems of electric generation, storage, and distribution-are
increasing in popularity. But while optimism about their adoption
grows, some energy experts caution the systems could be over-hyped.
ENERGY MARKETS
Market Dynamics Are Complicated as Coal Battles Natural Gas
Lower prices for natural gas have given it a competitive advantage over coal
in recent years. However, small changes in the price of gas could result in
large changes in which fuel supplies the bulk of power generation in the future.
Other variables, including power demand, energy efficiency standards,
transportation prices, and the impact of renewables, could also play a role.
CYBERSECURITY
Stepping Up Cybersecurity: Power Producers Move Ahead
49
The energy sector has been hit with almost one-third of the cyberattacks
against U.S. industry in recent years, making it a leading issue for power plant
operators. Cybersecurity must be top of mind, and companies need to look at
new technologies and processes to help thwart criminal activity.
COAL
A Proactive Program to Mitigate Coal Dust Reduces the
Risk of Explosions
Coal can be a dusty fuel and that dust can be highly explosive, posing a serious
risk to workers at coal-fired power plants. Plant operators have several
options available to reduce that risk, including both active and passive control
measures and design improvements that can be implemented to increase
safety and improve plant efficiencies.

3-D Laser Scanning of Nuclear Plant Piping Systems Reduces
Radiation Exposure

High-radiation areas are scattered throughout nuclear plants, and keeping exposure
to workers low is paramount. A 3-D laser scanning system helped one
plant map piping systems and determine where high-point vents should be
installed, reducing dose and improving worker safety in the process.
HEAT RECOVERY STEAM GENERATORS
Design Tomorrow's Combined Cycle Power Plant Using
Today's Lessons Learned
Today's construction boom in the combined cycle and cogeneration sectors
is great news for suppliers of gas turbines, heat recovery steam generators,
and engineer-procure-construct services. But before this boom advances
from artist's sketches to first fires, the designers of all those next-generation
combined cycles should pause to reflect on the lessons learned in the current
generation of combined cycle plants. (Visit powermag.com and search " Design
Tomorrow's Combined Cycle Power Plant " for this online-only exclusive!)
