The tension between the growing number of renewable energy projects and limited transmission capacity is reflected in Washington’s legislative agenda of establishing a national renewable portfolio standard and new transmission lines dedicated to moving renewable energy coast-to-coast. Even if those ideas become law, hurdles to the happy marriage of renewables and transmission remain.

Just as reports emerged earlier this year that NASA had abandoned, for lack of financial resources, its research into space-based solar power that would be harnessed via orbiting solar arrays beaming microwaves to earthly receivers, California’s Pacific Gas & Electric Co. (PG&E) wrote the California Public Utilities Commission (PUC) requesting its approval of a power purchase agreement from a similar technology.

Demand for renewable power is burgeoning as state governments (and maybe soon the U.S. federal government) impose increasingly rigorous environmental and procurement standards on the energy industry. Surprisingly, biomass cofiring has yet to attract much attention, even though it could help many utilities meet their renewable portfolio requirements, reduce carbon emissions, and solve other regional environmental problems. U.S. developers, investors, and regulators should consider including cofiring as part of the energy mix going forward.

In the world of North American Electric Reliability Corp. (NERC) Reliability Standards, each company (entity) that must comply with the standards determines for itself the scope and size of its compliance program, based on the scope and size of its operations.

Since 1882, when Thomas Edison installed the world’s first central generating plant in New York City, utility business models have varied little from the basic one: cover costs and generate profit by selling more electricity. But today, unprecedented challenges are sweeping through the industry. Soon utilities will face yet another new challenge: the large-scale implementation of distributed solar power, which can result in lower electricity sales. As solar implementation further challenges business-as-usual models, what’s a forward-thinking utility to do?

Increasingly fierce competition driven by deregulation and privatization is putting downward pressure on power plant operations and maintenance (O&M) budgets. Recently, lower natural gas prices have pushed natural gas – fired combined-cycle plants higher up in many utilities’ dispatch order in some regions, a welcome change from the twice-a-day cycling experienced by some plants during the past few years. However, with more operating hours comes more interest in plant operating availability, and that means increased emphasis on reliable gas turbine operation.

The recently released EX-5165 Sensor/Transmitter from ENMET Corp. is a three-wire 4-20 mA sensor for the detection of carbon dioxide in ranges from 0 to 500 ppm and 0% to 100% by volume. It also features a 24 VDC loop-powered transmitter. The nondispersive infrared sensor continuously monitors high concentrations of the gas, and it can […]

Caterpillar Inc. introduced a new family of remanufactured generator ends for standby, prime, and continuous power applications. The C32 and 3500 series Caterpillar engines have been used for applications ranging from distributed generation to prime power for remote communities. The first wave of remanufactured generator ends includes 34 part numbers, which are available worldwide in […]

I was putting the finishing touches on this month’s editorial when I received an email from a reader who owns a company that serves the power industry. He was very complimentary of an article I recently wrote. "Goes without saying," I was thinking to myself. However, actually saying it goes a long way in my book, and I enjoy hearing from readers — at least most of the time.

Rotork Process Controls introduced the SM-6000 S2, an electric rotary actuator for a wide range of heavy-duty damper drive applications found in power plants. The actuator provides high speeds and high torque for continuous modulating duty. It also offers positioning accuracy and can operate well in harsh and rugged environments. The SM-6000 S2 includes an […]
