Nanogrids and Microgrids are Keys to Decentralizing the Energy Infrastructure

Energy Manager Today, Sept. 13, 2016, by Carl Weinschenk.
http://www.energymanagertoday.com/nanogrids-and-microgrids-are-keys-to-decentralizing-the-energy-infrastructure-0126982/

"Nanogrids essentially is the microgrid concept — creating islands of power generation that rely on renewables and can either work in concert with or independently of the utility — taken to its logical conclusion. Indeed, a big piece of the value proposition may be that nanogrids are so small that they ease the transition to decentralized power."

Energy Secretary Moniz and Interior Secretary Jewell Announce New National Offshore Wind Strategy to Drive Deployment

Energy.gov, Sept. 9, 2016.

"U.S. Secretary of Energy Ernest Moniz and U.S. Secretary of the Interior Sally Jewell today announced the publication of a collaborative strategic plan to continue accelerating the development of offshore wind energy in the United States, the National Offshore Wind Strategy: Facilitating the Development of the Offshore Wind Industry in the United States, which could help enable 86 gigawatts of offshore wind in the United States by 2050. The strategy details the current state of offshore wind in the United States, presents the actions and innovations needed to reduce deployment costs and timelines, and provides a roadmap to support the growth and success of the industry."

The Future of Distributed Generation

Rural Electric Magazine, Aug. 2016, by Reed Karaim.

"Electric cooperatives have a long history of integrating distributed generation (DG) sources. But if you want a glimpse of the future of DG, you’ll find it in the wooded hills and valleys of northern Vermont, where Vermont Electric Cooperative is already living with challenges many co-ops will eventually face."

NARUC Rate Design Manual Reignites Debate Over Cost Shift, Value of Solar

Utility Dive, Aug. 4, 2016, by Herman K. Trabish.

"Regulators around the country are refereeing heated debates between utilities and distributed resource advocates. A guidebook is in the works to help them, but general agreement on its approach masks persisting disagreements between the two camps."

Why Home Solar Panels No Longer Pay in Some States

New York Times, July 26, 2016, by Diane Cardwell.
http://www.nytimes.com/2016/07/27/business/energy-environment/why-home-solar-panels-no-longer-pay-in-some-states.html?_r=1

"Thrust in the middle are utility regulators. Even if they support greening the grid through technology adopters like [cropped], the regulators are also responsible for ensuring that the utilities can afford to supply power to the largest number of customers at the most equitable rates. That includes people without the money or inclination to install solar collectors."

Many Industries Use Combined Heat and Power to Improve Energy Efficiency

Energy Collective, Jul 28, 2016.

"Combined heat and power (CHP) systems have long been used to reduce the overall energy intensity of industrial systems. There are two types of combined heat and power, depending on whether the system produces power first, then heat, or heat first, then power. In topping cycles, the hot exhaust of an electricity generator such as a natural gas turbine or reciprocating engine is used to provide process heat, hot water, or space heating for the site. According to preliminary 2015 data, topping cycles are used by 89% of total CHP capacity. In bottoming cycles, also referred to as waste heat to power, wasted heat from a furnace or other high-temperature industrial processes is recovered and used for power production."

State & Future of the Power Industry

Public Utilities Fortnightly & Navigant, June 2016.

"The Port of Los Angeles, North America’s largest port, plans to install a $26. 6 million solar microgrid this year, as it moves toward becoming the first marine terminal to operate solely on renewable energy."

Applying Combined Heat and Power Systems

Consulting-Specifying Engineer, June 2016, by Rodney V. Oathout.
http://www.csemag.com/single-article/applying-combined-heat-and-power-systems/6209f622802ca8a577b34246b4fc074a.html

"Cogeneration systems, often referred to as combined heat and power (CHP) systems, generate both electricity and thermal energy. As they become more common in the United States, engineers must understand the nuances and design strategies for successful application."

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."
