Power in Peru
Although Peru has been one of the best-performing economies worldwide over the last decade, its energy sector is still small in absolute numbers. Consumption levels per capita are low, even by Latin American standards, and demand growth is highly dependent on new mining investments. Successive governments have kept energy prices low; and regional interconnection, which […]

Legal & RegulatoryBest Practices for Aligning Safety Metrics, Incentives, and Performance
The Occupational Safety and Health Administration requires certain incidents to be recorded and reported, which generates a set of statistics that many companies use to gauge safety performance. However, other metrics may be better predictors. The Occupational Safety and Health Administration (OSHA) requires all employers with more than 10 employees, and whose establishments are not […]

RenewablesRough Seas for Ocean Energy
The world’s ocean energy sector, which has over the past few years seen its share of developmental ebbs and flows, suffered a major storm this November after Siemens Energy said it would sell its tidal power arm and Pelamis Wave Power separately failed to raise needed funds to continue development. Siemens in February 2012, with […]

CoalAmerican Electric Power: A Coal Powerhouse Repositions Itself
American Electric Power, one of the premier generating utilities in the U.S., is caught between a deregulated rock—wholesale competitive capacity markets that don’t, in the company’s opinion, value solid equipment over ephemeral demand response—and a regulatory hard place of increasing federal government rules that devalue on-the-ground coal-fired generation. Add the competitive challenge of cheap natural […]

Distributed EnergyAir Force Fields World’s Largest Vehicle-to-Grid Demo
On Nov. 14 at Los Angeles Air Force Base, California (L.A. AFB), U.S. Air Force officials unveiled the Department of Defense’s (DOD’s) first nontactical vehicle fleet composed entirely of plug-in electric vehicles (PEVs). Actual rollout of the 42-vehicle fleet happened prior to the official ceremony, Christina Greer of the base’s Public Affairs office told POWER, […]

O&MOperational Considerations When Burning Higher-Chlorine Coal
An increasing supply of low-cost higher-chlorine coal is prompting many U.S. generators to give the fuel serious consideration in spite of its reputation for causing corrosion. Though corrosion can be a consideration, it’s not always caused simply by the fuel switch. Understanding the various chemical interactions, as well as operational and emissions pros and cons, […]

Who Cares About Energy Efficiency?
Most readers will receive this issue while they are experiencing Northern Hemisphere winter, with its colder temperatures and higher energy bills, so it’s fitting that several articles address efficiency. You’ll find discussions of combined heat and power (CHP) as well as a refresher on the various ways to enhance thermal unit efficiency and thereby improve […]

O&MUnderstanding Coal Power Plant Heat Rate and Efficiency
Proposed U.S. standards for reducing carbon emissions from existing coal-fired power plants rely heavily upon generation-side efficiency improvements. Fuel, operations, and plant design all affect the overall efficiency of a plant, as well as its carbon emissions. This review of the fundamentals of coal plant efficiency, frequent problems that reduce efficiency, and some solutions for […]

World Faces Challenges in Meeting Access, Renewables Goals
The world will fall short of the goal of providing universal sustainable electricity access by 2030 set by the United Nations and World Bank without “immediate concerted action” by governments, industry, and the international community, according to a survey of utilities around the world conducted by the Global Electricity Initiative (GEI). The GEI is a […]

CoalScrubbing Coal Plant NOx Emissions with Electron Beams
An unnamed power company and the U.S. Naval Research Laboratory (NRL) have partnered to test a concept proven to work at a small scale that applies pulsed electron beam technology to slash coal plant nitric oxide and nitrogen dioxide (NOx) emissions. The concept (Figure 3) essentially involves directing electron beams from a cathode into the […]

POWER Digest (February 2014)
Germany Approves Plan to Slash Carbon Emissions. Germany’s cabinet on Dec. 3 approved a new policy package to meet ambitious targets that would reduce the nation’s carbon emissions at least 40% by 2020 compared to 1990 levels. The plan proposes that 22 million metric tons of carbon dioxide emissions will be saved by power plants, […]

Legal & RegulatoryAustralia’s Renewables Impasse Weighs Heavily on Generators
The long-drawn-out political impasse on Australia’s review of its Renewable Energy Target (RET) has generators reeling from what they say are “constant policy changes and distortions from successive interference by governments.” Australia’s RET, which has been in operation since 2001, was increased in 2010 to require that about 20% of the nation’s then-projected demand in […]

O&MRobotic Inspections of Nuclear Power Plant Storage Tanks
Nuclear power station water storage tanks, located above ground or underground, are constructed of aluminum, stainless steel, or carbon steel. All have naturally occurring electro-chemical processes that can eventually deteriorate the metal, resulting in leaks. Defects that develop on the underside of tank floors are particularly difficult to detect and measure. The Nuclear Energy Institute […]

Removing Regulatory Roadblocks for PEVs
One oft-cited roadblock to widespread adoption of plug-in electric vehicles (PEV) is a lack of charging infrastructure, commonly referred to as electric vehicle supply equipment (EVSE), or charging stations. While Tesla is well known for designing electric vehicles that can travel more than 250 miles on a single charge, most PEVs can only travel 60 […]

GasCHP: A Rocky Path for a Promising Approach
Combining electric power production with use of steam for heating, cooling, and industrial processes is an old idea that had a brief boom in the U.S., kicking off the rise of non-utility generation. Since then, combined heat and power, or cogeneration, has become a niche market player. What happened? In the late 1990s, the University […]

RenewablesGlobal CHP Still Struggling to Break Out of Its Niche
Despite its efficiency and environmental benefits, combined heat and power (CHP) generation has languished at around 10% of worldwide capacity for more than a decade. But a global review shows growth in some sectors and promising new technology on the way. The statistics are both eye-opening and somewhat depressing. Globally, according to the International Energy […]

CoalOptimizing Combined Heat and Power in China
As it struggles to grow its economy while improving air quality in urban areas, China is updating its energy delivery infrastructure. A key part of that plan is switching from coal-fired to gas-fired combined heat and power plants. To push efficiency even further, some plants are turning to synchronous clutches. The developed world has done […]
