The power industry hasn't yet reached the level of cyber sophistication depicted in the movie
The Matrix, but the number of interconnected devices and communication systems has already
made constant attention to cybersecurity a must. Image courtesy: iStockphoto
COVER STORY: CYbERSECuRiTY
26 Ensuring the Cybersecurity of Plant industrial Control Systems
Although industrial control systems (ICSs), including those used in power plants,
integrate common information technology components, they also entail much more.
Consequently, the skills needed for designing and securing such systems are more
complex-and scarce. Case studies describe power plant cybersecurity events that
have already happened, while a checklist for achieving a secure ICS operating environment
could help your plant avoid becoming a future case study.
34 Guidance on Cybersecurity for the Electricity Sector
Cybersecurity supports the reliability of the electric sector and must address interconnected
systems in grid modernization. EPRI underscores why cybersecurity
needs to be addressed in all systems, not just critical assets.

38 Particulate Matter Air Quality Standards Continue to Evolve
Everything you've ever wanted to know (or at least need to know) about the varieties
of particulate matter, its regulation, and permitting and measurement considerations.

46 boosting CSP Production with Thermal Energy Storage
Energy storage is one way to increase grid flexibility, and many storage options are
available or under development. This article, contributed by the National Renewable
Energy Laboratory, looks at a technology already being used at scale-thermal energy
storage deployed with concentrating solar power (CSP).

52 unconventional Gas: The Great Game-Changer
IHS CERA Chairman and Pulitzer Prize-winning author Dr. Daniel Yergin talked
with POWER about his latest book, U.S. energy policy, and the various uses for
all that gas.

54 Japan Scrambles to Revamp its Electricity Sector
The March 2011 earthquake and tsunami were just the beginning of Japan's energy
crisis. Though the island nation had developed an energy policy (unlike the U.S.), the
natural disaster and nuclear catastrophe have required a wholesale rethinking of the
way forward. Here's a look at how Japan has coped with restraints to date and what
its options are for the near and long-term future.
