Using Probability of Exceedance to Compare the Resource Risk of Renewable and Gas-Fired Generation

Lawrence Berkeley National Laboratory (LBNL), Mar. 2017, by Mark Bolinger.
https://emp.lbl.gov/sites/default/files/lbnl-1007269.pdf

"This paper presents a new framework, grounded in statistical concepts related to probability of exceedance (and confidence intervals more broadly), to incorporate resource risk into decision-making processes. This framework recognizes that the same probability of exceedance concepts that are regularly used to characterize the uncertainty around annual energy production for wind and solar projects can also be applied to natural gas price projections, allowing one to develop a probabilistic range of projections for not only wind and solar capacity factors, but also natural gas prices."

An Assessment of the Economic Potential of Offshore Wind in the United States from 2015 to 2030

National Renewable Energy Laboratory (NREL), Mar. 2017.
http://www.nrel.gov/docs/fy17osti/67675.pdf/

"This study describes an assessment of the site-specific variation of levelized cost of energy (LCOE) and levelized avoided cost of energy (LACE) to understand the economic potential of fixed-bottom and floating offshore wind technologies in major U.S. coastal areas between 2015 and 2030."

Strategies for Peak Shaving and Power Security

Forester Daily News, Mar. 2017, by Ed Ritchie.
http://foresternetwork.com/daily/energy/strategies-for-peak-shaving-and-power-security/

"In Part 1 of a 5-part series, author Ed Ritchie takes readers through the process of understanding reliable energy strategies like peak shaving for business applications. Through this series, he explains the multifaceted components of commercial building energy systems that might include utilities analysis software, commercial generators, and other onsite technologies important in maintaining reliable power generation."

Renewable Energy and Microgrids Offer Colleges a Path to Cutting Carbon: Report

Microgrid Knowledge, Mar. 27, 2017, by Lisa Cohn.

"It’s no secret that colleges and universities are some of the biggest microgrid users. But a new report says we should see more renewable energy and microgrids at these institutions. The report, from Environment America Research & Policy Center, 'Renewable Energy 100: The Course to a Carbon-Free Campus,' says that the shift to 100 percent renewable energy can be led by colleges and universities eager to become carbon neutral."

Preparing For More DG On the Grid: No Two-Way Power Flow About It?

Public Power, Mar/Apr 2017, by Laura D'Alessandro.

"Installing solar panels seems simple, according to all those companies selling them. Just sign up, invite someone onto your roof to install them, and boom, you’re in business — generating power even when the grid goes down. Right? Not exactly."

Top Six [Wind] News Stories To Start 2017 as First Quarter Closes

AWEA Blog, Mar. 31, 2017, by Anna Luke.
http://www.aweablog.org/top-six-good-news-stories-builds-2017-first-quarter-closes/

"Since the start of the year, there have been almost too many exciting developments in wind power to count. But we’ll try! Here are six top news items from the first three months of the year."

A Cheaper HRSG [Heat Recovery Steam Generator] with Advanced Gas Turbines

Power Engineering, Mar. 2017, by S. Can Gülen, Ilya Yarinovsky, and Dave Ugolini.
http://www.power-eng.com/articles/print/volume-121/issue-3/features/a-cheaper-hrsg-with-advanced-gas-turbines.html

"Present state-of-the-art in gas turbine combined cycle (GTCC) design is three-pressure, reheat (3P-RHT) steam bottoming cycle with steam generation at three different pressure levels. The goal is to maximize total steam generation and steam turbine generator power output for a given gas turbine exhaust energy and, thus, to maximize combined cycle efficiency."

Solar Experiment Lets Neighbors Trade Energy Among Themselves

New York Times, Mar. 13, 2017, by Diane Cardwell.
https://www.nytimes.com/2017/03/13/business/energy-environment/brooklyn-solar-grid-energy-trading.html?_r=0

"In a promising experiment in an affluent swath of [Brooklyn], dozens of solar-panel arrays spread across rowhouse rooftops are wired into a growing network. Called the Brooklyn Microgrid, the project is signing up residents and businesses to a virtual trading platform that will allow solar-energy producers to sell excess-electricity credits from their systems to buyers in the group, who may live as close as next door."

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."

Oregon’s Largest Solar Project Begins Construction

PV Magazine, Feb. 27, 2017, by Christian Roselund.
https://pv-magazine-usa.com/2017/02/27/oregons-largest-solar-project-begins-construction/

"While SunPower continues to bleed red ink, the company is also breaking new ground for high-efficiency solar, in some cases literally. Today SunPower announced that construction firm Moss has begun work on a 56 MW solar PV project in Eastern Oregon, using its E-Series PV modules and its modular Oasis platform for utility-scale projects."
