Microgrid Momentum: Building Efficient, Resilient Power

C2ES: Center for Climate and Energy Solutions, Mar. 2017, Doug Vine, et. al.
https://www.c2es.org/docUploads/microgrid-momentum-03-2017.pdf

"When Hurricane Sandy cut off power to millions of homes and businesses in the Northeast, a few areas, mostly parts of universities, kept the lights on using their own power generation systems. This ability to sustain electricity service during widespread natural disasters is one reason for the growing interest in microgrids. But they offer other important benefits as well. By increasing efficiency, integrating renewables, and helping manage energy supply and demand, microgrids can reduce greenhouse gas emissions and ave energy. For utilities, microgrids can ensure power reliability in remote areas. Microgrids also appeal to those who want to disconnect from utility bills."

Best Practices for CHP Development

Power Engineering, Feb. 2017, by Thomas G. Adams.
http://www.power-eng.com/articles/print/volume-121/issue-2/features/best-practices-for-chp-development.html

"Combined heat and power (CHP) projects promise many benefits to a wide array of large energy users, and CHP has a long history of adoption and success in many industries. Despite its wide adoption, many energy users considering the development and installation of a CHP project face a set of tasks and challenges that they are not always fully equipped to handle since their primary business is usually quite different from power and thermal energy production. By focusing on best practices from the start of project development, to execution, and on to long term operation and maintenance, new owners of CHP systems can mitigate risks and maximize the chances of success for their project."

Steam Turbine Retrofits: Methods to Extend Turbine Life and Improve Performance

Power Engineering, Feb. 2017, by Muhammad Saqib Riaz. http://www.power-eng.com/articles/print/volume-121/issue-2/features/steam-turbine-retrofits.html "A steam turbine is designed and optimized for a specific set of steam conditions. After long term operations either the steam path components deteriorate or due to changes in steam conditions, a re-optimization of the steam path components is required to regain higher turbine performance. Steam Turbine retrofits are performed to achieve various goals such as improved turbine efficiencies, heat rate or power output. Retrofits are also performed to address turbine reliability and or maintenance issues. Availability of newer technologies and materials for steam path components can be utilized to not only increase steam turbine performance, but also to extend maintenance intervals, and extend life. Retrofits can also accommodate required changes to the thermal cycle based on emerging needs of the power plant. The effectiveness of the retrofit is achieved by ut ... Read the rest of entry »

Optimized Energy Recovery

ASHRAE Journal, Jan. 2017, by Marvin Kirshenbaum.
http://ashraecok.org/images/downloads/Technical_Literature/journal_2017_01_optimized_energy_recovery.pdf

"This article addresses extending the application of waste heat recovery to both reheat and primary heating, allowing for a heat reclaim system no longer restricted to seasonal operation."

Where To Place Air-Cooled Chillers

Engineered Systems, Feb. 2017, by Kishor Khankari.
http://www.esmagazine.com/articles/98146-where-to-place-air-cooled-chillers

"Warm discharge plumes sweeping back into air-cooled condensers is nobody’s idea of an ideal performance environment. This CFD study shows how wind speed, wind direction, spacing between chillers, and separation from adjacent buildings all factor into the conversation about the best defense against unwanted hot air."

Fluid Cooling In Data Centers — If Not Now, When?

Engineered Systems, Jan. 2017, by Kevin Dickens.
http://www.esmagazine.com/articles/98105-fluid-cooling-in-data-centers-if-not-now-when

"Trends don’t always follow the expected path (or timeline), but the basics remain the basics and increased cabinet density remains inevitable. Let’s revisit the progress of liquid in data center strategy and the tenets of a future-proof(ish) hybrid design for today."

Design of a High-Temperature-Hot-Water-Plant Expansion

HPAC Engineering, Jan. 2017, by Eric Chrencik.
http://hpac.com/heating/design-high-temperature-hot-water-plant-expansion

"There are four main components of HTHW-plant design:
  • HTHW-generator selection.
  • Pump selection.
  • Consideration of system expansion and makeup.
  • Stress analysis and piping layout.
This article discusses all four for a recently completed HTHW-plant expansion at George Mason University in Fairfax, VA."

Why Net Metering Matters For Commercial Solar, Too

Solar Industry, Jan. 2017, by Graham Smith.
http://issues.solarindustrymag.com/article/why-net-metering-matters-for-commercial-solar-too

"The C&I sector is often overlooked when it comes to the battle over NEM reform.... 2017 promises to hold many more discussions across the nation about NEM reform, from northwestern states like Utah, to the tip of the Northeast in New Hampshire and Maine. As policymakers and industry executives come together to decide on the future of solar, there must also be discussions about the effects of NEM reforms on C&I."

Alcatraz: One of the Largest Microgrids in the United States

U.S. Dept. of Energy, Jan. 26, 2017, by Mike Mueller.
https://energy.gov/eere/articles/welcome-alcatraz-one-largest-microgrids-united-states

"Each year, more than 1.5 million people tour Alcatraz Island to visit its iconic prison. But, most people don’t realize that this 22-acre site, located in the middle of the San Francisco Bay, is also home to one of the nation’s largest microgrids. The island is equipped with a solar-diesel hybrid power system that most visitors probably won’t notice."
