Electric utilities across regions are many times interconnected for improved economy and reliability. Interconnections allow for economies of scale, allowing energy to be purchased from large, efficient sources. Utilities can draw power from generator reserves from a different region in order to ensure continuing, reliable power and diversify their loads. Interconnection also allows regions to have access to cheap bulk energy by receiving power from different sources.

Guest Commentary: The New Era of CHP

What do the Excelsior Hotel, Cathedral Village Retirement Home, Grand County High School, Statz Farms, Willard Apartments, and Supreme Sports Club have in common? They all represent the new face of the combined heat and power (CHP) market—relatively small commercial facilities that are installing CHP to save money on energy

Building Design with Sea Rise in Mind

There’s an unusual occupant in the penthouse suite of many Manhattan high-rise buildings today. It’s not America’s wealthy elite or mice with multi-million dollar views. The premium, top-floor space is increasingly occupied by emergency generators meant to sustain building residents when disaster strikes.

“Along coastlines and lake shores and riverfronts across

Elements of Critical Power Systems and Their Management

Elements of Critical Power Systems and Their Management

A single power interruption can cripple a healthy company, says Bhavesh Patel, director of marketing of Emerson’s ASCO Power business. “Not having adequate onsite power can be the ‘Achilles heel’ of a business, but the controls for operating, monitoring, diagnosing, and producing a variety of mandatory reports on these power

Making Power Multitask With CHP/CCHP

Making Power Multitask With CHP/CCHP

Cogeneration, or combined heat and power (CHP), uses a heat engine or power station to generate electricity and heat for onsite uses. Trigeneration, or combined cooling, heat, and power (CCHP), is the simultaneous generation of electricity and useful heating and cooling as a result of the combustion of fuel or

Gas Turbine Generators Bring Power Where It’s Needed

Gas Turbine Generators Bring Power Where It’s Needed

Because of their small footprint and light weight, gas turbines are ideally suited for mobile and distributed power applications that bring power closer to the point of use, notes Claudette Carmine Harris, marketing communications for Solar Turbines.

Solar Turbines, Inc. manufactures gas turbine-driven generator sets from 1 to 22 MW for

Achieving New Heights

Achieving New Heights

Energy professionals know that backing up critical data means having the right power protection strategy in place to ensure that facility downtime doesn’t impact business. During the course of operation, power sags, surges, and outages are unavoidable and capable of damaging valuable equipment and cutting off access to important information.

Switchgear Arc Protection and Resistance

Switchgear Arc Protection and Resistance

Arc flash events in electrical distribution systems can be devastating, costing up to $15 million in direct damages and indirect costs, such as health care, workers compensation, and others (EPRI 1999). An arc flash can generate temperatures over 35,000°F and projectile-producing pressures equivalent to 700 miles per hour, and is

Microgrid & Microturbine Power Trends

Microgrid & Microturbine Power Trends

There are interesting developments happening with microgrids these days. Utilities are adding them to stabilize their grids, and communities are developing a peer-to-peer consumer energy trading system to buy and sell electricity generated by their solar systems.

Microgrids have also become the hottest concept as alternatives to the aging utility grid—passing up

Power Security

Power Security

As described by the US Department of Energy (DOE), microgrids are localized grids that can disconnect from the traditional grid to operate autonomously, help mitigate grid disturbances for faster system response and recovery, and strengthen grid resilience.

Editor’s Comments: The Path to Power Security

According to Greek mythology, when Odysseus bravely entered the labyrinth to vanquish the Minotaur, thanks to a gift from Ariadne—a thread that traced his path through the labyrinth’s dark passageways—the Athenian hero was able to find his way back out into the light.

Many communities are considering, researching, or implementing microgrid solutions. The underlying rationale often involves complex business, operational, and economic issues. See our FREE Special Report: Understanding Microgrids. Download it now!
