The role of an estimator has evolved, yet it remains rooted in the principles that defined it. A 41-year estimating veteran helps illustrate the means by which estimating has shifted and how the measure of the estimator’s skills plays a key role.
One of renewable energy sources’ biggest challenges is the intermittency of power generation. Finding a way to store power for later use helps make renewables more practical for tying into the grid where demand does not always coincide with the wind or the rising sun.
Lighting continues to be a huge chunk of a building’s annual energy costs—between 20 and 40 percent. While the need for light will never go away, analyzing its costs through energy modeling can help secure the installation of more efficient technologies.
From talking to electrical contractors lately, I know it’s still tough to get profitable work in the current economy. However, I also find most of the contractors who have prepared well for such a poor economic situation are maintaining a substantial workload.
Intelligent visual surveillance systems monitor persistent and transient objects within specific environments in real time. The primary intentions for systems are to provide an automatic interpretation of scenes and to understand and predict the actions and interactions of the observed objects.
With the economy still reeling from the effects of recession, unemployment, and wavering business and consumer confidence, electrical contractors (ECs) are re-evaluating their businesses and taking on new and different roles and business models in an effort to remain competitive.
Across the country, electrical contractors currently are or will be garnering contracts to upgrade traffic signals—replacing the incandescent bulbs with light-emitting diode (LED) lamps. Take a few tips from one company that has successfully completed a major project of this type.
In the years that renewable power has been fighting for market competitiveness, overcoming the high capital costs compared to conventional energy sources has always been the big challenge. Now, for at least one form of renewable energy, it appears that challenge may have been met.
The Lucky Corridor, approximately 93 miles of planned new electrical transmission, consisting of double-circuit 230-kilovolt (kV) line in New Mexico, cleared a hurdle with a memorandum of understanding (MOU) with the Western Area Power Administration, a power marketing administration in the U.S.
It’s no secret that, with deeper systems integration, new technologies, and a focus on efficient and alternative energies, the electrical industry is growing and changing in ways that were hard to predict even just a decade ago.
As thousands of attendees gathered at the Lightfair International Conference in Las Vegas on May 10, 53 commercial light-emitting diode (LED) indoor lighting products were recognized and awarded in the fourth annual Next Generation Luminaires (NGL) solid-state lighting design competition.
Most utility reserve margins are adequate to meet peak demands. That is the assessment of the North American Electric Reliability Corp. (NERC) as the nation has hit the summer months in which heat can strain supplies.
To say the least, project labor agreements (PLAs) have been a controversial issue for the construction industry. And like many controversial issues, debate and partisanship sometimes leads to the unfortunate consequence of delaying much-needed jobs.
Strict regulations to limit the toxic air emissions from coal-fired plants in the United States are working. Many utilities striving to meet these tighter standards are finding they can’t afford the high costs of upgrades and retrofits to their aging facilities.
