Avoiding the Fate of Atlanta, Pittsburgh Looks to Build an Airport Microgrid

airport microgrid

Pittsburgh wants an airport microgrid. And developers -- a lot of them -- want to build it. The Allegheny County Airport Authority has received 64 responses to its request for expressions of interest seeking a developer to design, build, own and operate a microgrid at the Pittsburgh International Airport. The authority is considering making … [Read more...]

Power-to-Gas in Microgrids: Competitive with Batteries?


Power-to-gas, a technology that converts excess renewable energy to gases that can be stored, is cost-competitive with lithium-ion batteries in microgrids, according to Matt Gregori, technology development manager, Southern California Gas. Gregori spoke at a solar conference last week at the University of California, Riverside. Southern … [Read more...]

Solar Plus Storage Microgrids Bring Relief to Puerto Rico — And Hint of the Future

solar plus storage microgrids

At the tail end of installing 15 solar plus storage microgrids across Puerto Rico -- all of the work charitable -- Sonnen and Pura Energia are providing humanitarian relief and a hint of the energy model the island could become. The latest installation, for a school in the mountain town of Orocovis, comes as over 14 percent of Puerto Ricans … [Read more...]

Too Few Microgrids for Puerto Rico? Or Too Many? Depends on Who You Ask


With power still not fully restored, Puerto Rico finds itself forced to quickly answer questions about microgrids that much of the U.S. mainland has yet to tackle. How many microgrids are enough? What’s the utility role? What price should customers pay for microgrid power? How green should they be? And what defines a microgrid, … [Read more...]

Long Before Microgrids were Called Microgrids: The Russelectric Story


You might say the world’s just catching up to Russelectric. Long before microgrids were called microgrids, the Massachusetts-based company offered the technology. “We have been building microgrid and distributed energy controllers and systems for 50-60 years, they just weren't calling them that,” said John Stark, Russelectric’s marketing … [Read more...]

Combined Heat and Power is the Dominant Microgrid Technology…For Now


Combined heat and power (CHP) is the dominant form of microgrid technology now, but solar energy threatens to usurp its position by 2026. That's the word from Navigant Research in its new report, Microgrid Enabling Technologies Market Overview. The report finds that among generation technologies deployed within microgrids, CHP leads with 655 … [Read more...]

The Double Life of Microgrids: Eaton’s Solution to a Cybersecurity Problem


When it comes to cybersecurity, microgrids live a dichotomy. They can block the ill effects of a hacked power grid. But they also can invite trouble. Because of their ability to island from the grid, microgrids offer protections to their customers during an attack on the grid. If a hacker causes a grid outage, the microgrid can separate … [Read more...]

Can Utilities Rate Base Energy Storage as a Distribution Asset?

Rate Base Energy Storage

Can utilities rate base energy storage as a distribution asset? Texas is now tackling this big question, with the potential to set policy that could have national ramifications. The question arose when American Electric Power (AEP) asked the Public Utility Commission (PUC) of Texas to approve its proposal to install numerous grid-scale batteries … [Read more...]

NYPA to Re-Think Albany Microgrid Following Pressure to Add Renewables

Albany microgrid

Under pressure from local advocates, the New York Power Authority (NYPA) says it will take a second look at plans for a 16-MW Albany microgrid project to see if it can incorporate renewable energy. As originally conceived the Albany microgrid would use combined heat and power (CHP) to supply 90 percent of the power, as well as heating and … [Read more...]

Microgrids Powered by a Sidewalk? Siemens and Pavegen Are On It


Power plants aren’t what they used to be. Consider a new partnership formed by Siemens and UK startup Pavegen that paves the way for sidewalks to act as power plants for microgrids. Pavegen produces electricity from footsteps by way of interactive flooring tiles. Each step creates the equivalent of 20 seconds of light from an LED bulb. In … [Read more...]
