Understanding Cogeneration Systems

Pure Power (supplement to Consulting-Specifying Engineer), Summer 2015, by Jerry Schuett and David Cummingham.
http://www.csemag.com/single-article/understanding-cogeneration-systems/ebec65943f512c49199b852db0b51104.html

"Cogeneration systems—also known as combined heat and power (CHP) systems—generate both electricity and usable thermal energy. These systems typically are used on campuses that have high heat load requirements." Describes three CHP system prime movers: back-pressure steam turbine, combustion turbine, and reciprocating engine.

Implementing Microgrids: Controlling Campus, Community Power Generation

"Microgrids are subsets of the regional electrical grid that have the ability to operate independent, or “island,” from the local utility. Microgrids normally operate in parallel with the utility, but they can operate in an isolated mode when utility service is interrupted or providing poor power quality. The design and operation of microgrids are optimized around the needs of the specific end users they serve."

"One of the oldest cities in the United States, Boston is supported by an innovative district energy system that integrates thermal energy recycled from the electric generation process for heating and cooling. Since acquiring the district system in 2005, Veolia North America has made significant investments to improve network efficiency and reduce environmental impacts, culminating in the completion of its $112 million 'green steam' pipeline project in 2014."

How Energy Efficiency Financing Can Help States Meet Clean Power Plan Goals

American Council for an Energy-Efficient Economy (ACEEE), May 27, 2015.
http://aceee.org/blog/2015/05/how-energy-efficiency-financing-can

"Today, ACEEE is releasing the second in a series of step-by-step guides that help states claim emissions reductions resulting from energy efficiency programs and policies. Navigating the Clean Power Plan: A Template for Including Energy Efficiency Finance Programs in State Compliance Plans is focused on helping states incorporate financing programs and policies into their plans for complying with the EPA Clean Power Plan. The tool provides an overview of some types of financing approaches that may be well suited for Clean Power Plan compliance."

NREL Highlights 2014 Utility Green Power Leaders

National Renewable Energy Laboratory New Release, May 2015.
http://apps3.eere.energy.gov/greenpower/news/news_template.shtml?id=2034

"The Department of Energy's National Renewable Energy Laboratory (NREL) has released its assessment of leading utility green power programs. Using information provided by utilities, NREL has developed "Top 10" rankings of utility green power programs for 2014 in the following categories: total sales of renewable energy to program participants, total number of customer participants, the percentage of customer participation, and green power sales as a percentage of total utility retail electricity sales."

Mining for Lithium in Geothermal Brine: Promising but Pricey

Power Magazine, Mar. 2015, by Gail Reitenbach.
http://www.powermag.com/mining-for-lithium-in-geothermal-brine-promising-but-pricey/?printmode=1

"Brine, the waste stream of the geothermal power production cycle, is usually considered a nuisance. High in corrosive minerals, even when reinjected, it’s challenging to manage. So when Simbol Inc. showed it had a way to turn this waste stream into a revenue stream by mining it for high-value minerals like lithium, a lot of people got excited. However, just as this article was going to press, a lot of people got laid off."

Centralized & Decentralized PV Power Plants: Vendor Perspectives

SolarPro, Mar/Apr 2015, by Joe Schwartz.

"As the capacity of utility-scale PV plants has increased in the US, so has the capacity of the centralized power-conditioning units used in these projects. Today, many plants utilize factory-integrated skids that combine inverters, medium-voltage transformers and switchgear into packages that range in capacity from 1 MW to 2.5 MW. These integrated systems offer project developers many advantages, including optimized component compatibility, as well as reduced installation time and expense."
