Real-world Research at Wanapum Dam

Hydro Review, May 2016, by Yannick Baril, Maxim Bergeron, Jose Figueroa, and Jeff Niehenke.
http://www.hydroworld.com/articles/hr/print/volume-35/issue-4/articles/real-world-research-at-wanapum-dam.html

"Repair work at Grant County Public Utility District's Wanapum Dam in Washington offered an uncommon chance to perform studies on operating machinery."

U.S. Microgrid Market Development

Power Magazine, May 2016, by Gail Reitenbach.

"Microgrids have been around for decades, but today, more potential customers, owners, technologies, and vendors than ever are part of the market. Increased interest in this special grid resource means there’s more competition, which is generally a good thing, but there are also new challenges."

New Cogen System Triples Energy Output from Biogas at Oregon WWTP

Biomass Magazine, May 2015, by Katie Fletcher.

"On May 4, Clean Water Services, Energy Trust of Oregon and the Oregon Department of Energy formally announced the implementation of a new cogeneration system that converts wastewater and grease into renewable energy. The innovative system, which is part of Clean Water Services Durham Treatment Facility, is the third cogeneration system in Oregon to codigest fats, oils and grease (FOG)."

"enerG Magazine's authoritative feature on the leading U.S. states Canadian provinces in wind power, and the largest wind power projects in the U.S. and Canada." 

GE is Building America’s First Offshore Wind Farm

Wind Systems Magazine, Apr. 2016.
http://www.windsystemsmag.com/article/detail/1183/ge-is-building-americas-first-offshore-wind-farm

"New wind farms added more than a quarter of total new power generation capacity in the United States between 2010 and 2014, reaching 75,000 MW at the end of last year. With the exception of China, no other country has more. However, despite America’s abundance of coastline, its wind farms spin exclusively on shore. But that’s about the change."

Staving Off a Sunset [Biomass in California]

Biomass Magazine, Apr. 2016, by Bruce Dorminey.

"While California’s biomass power industry continues its struggle for survival, fuel suppliers are left without a home for mounting materials."

Maximizing MWh: A Statistical Analysis of the Performance of Utility-Scale Photovoltaic Projects in the United States

Lawrence Berkeley National Laboratory, Mar. 2015.
https://emp.lbl.gov/sites/all/files/lbnl-1004374.pdf

"This paper presents the first known use of multi-variate regression techniques to statistically explore empirical variation in utility-scale PV project performance across the United States."

New Plant Design Options Expand Geothermal Power Operations

Power Magazine, Apr. 2016, by Allie Nelson.
http://www.powermag.com/new-plant-design-options-expand-geothermal-power-operations/

"Geothermal energy may not be a large contributor to the U.S. power mix—it provided less than 0.5% of total U.S. generation in 2015—but it is a reliable and dispatchable renewable energy source that plays well with others. And while the concept is old, new technology is making it easier for grid operators to utilize this important resource."

Weighing Costs and Benefits in Hydropower Maintenance and Upgrade Decisions

Power Magazine, Apr. 2016, by Aaron Larson.
http://www.powermag.com/weighing-costs-benefits-hydropower-maintenance-upgrade-decisions/

"Choosing whether to maintain or upgrade hydropower plant components can be difficult. Poor original equipment reliability can force changes, but often a detailed cost-benefit analysis is needed to make decisions. Understanding how others have tackled the process can help ensure success at your plant."

The State of Wind Farm Underperformance Syndrome

Wind Systems Magazine, Mar. 2016, by Bruce H. Bailey.
http://www.windsystemsmag.com/article/detail/1149/the-state-of-wind-farm-underperformance-syndrome

"It is fair to expect that the energy output of an operating wind farm should be close to what it was designed to produce. If the wind conditions for a particular site are well-measured and the selected turbine is a well-known model, then logic would conclude that the energy prediction process is fairly straightforward. But is this an oversimplification? Industry experience has shown that it is, since the majority of operating wind farms don’t meet their predicted P50 energy values in an average year."
