Cogeneration (Combined Heat and Power or CHP) is the simultaneous production of electricity and heat, both of which are used. The central and most fundamental principle of cogeneration is that, in order to maximise the many benefits that arise from it, systems should be based on the heat demand of the application.

Cogen Case Study: Ronald McDonald House, New York City

What began in 1974 as a Shamrock Shake-driven fundraiser to help families with sick children is today a network of 322 Ronald McDonald Houses in 57 countries. The first Ronald McDonald House (RMH), in Philadelphia, PA, was meant to serve as a “home away from home” for families spending time

Why Microgrids Are Inevitable

Why Microgrids Are Inevitable

The fledgling electric utility companies that emerged after Thomas Edison opened his small Pearl Street, New York City, NY, power station in 1882 originally focused on distributed energy generation (DEG) operating within a microgrid. Edison envisioned that the electric utility industry would involve small firms generating direct current (DC) power

Load Bank, ATS, and UPS Applications Provide Secure Power

Editor’s note: This article first appeared in the November/December 2015 edition of Business Energy.

Facilities depend on an uninterruptible power supply or power source (UPS) to provide nearly instant power to a load when the main power fails, or an automatic transfer switch (ATS) to switch the load between the utility power and a backup

“Waste not want not” is a respected proverb in many engineering applications. However, according to the three laws of thermodynamics, waste heat is inevitable in any working system. And, while it is physically impossible to prevent the generation of waste heat, a power system operator can make a virtue out

Connectivity And Resilience

Connectivity And Resilience

The great northeast power blackout of 2003 was a reminder that reliance on large grids has widespread implications. The power outage—lasting several days in some areas—affected millions in the US and Canada. Nearly a decade later, Hurricane Sandy left the area without power for weeks. Many in the energy industry

Building Controls: The Heart of Energy Efficiency

Building Controls: The Heart of Energy Efficiency

Digital technology has created a revolution in building controls, relegating old pneumatic instruments to the antique shops along with typewriters and calculating machines. Now, a control system can allow a technician to turn fans on or off, and/or modify temperatures or lighting in a structure from a tablet or laptop

Microgrids on the March

Microgrids on the March

Microgrids are becoming the transformative technology in today’s energy industry, and are putting many utilities on the defensive. A few utilities want to adopt or coopt the technology, depending on one’s perceptions, creating tensions among utility and industry stakeholders. The latter believe microgrid resources can best be delivered by private companies.
