A Surprise to Analysts: Less CHP in Microgrids, More Solar

CHP

Combined heat and power (CHP) provides year-round baseload energy in microgrids — something renewable resources don’t do. Yet solar PV now overshadows CHP in planned microgrid projects, according to a new microgrid database by ICF. “We see a lot of installed CHP systems in operating microgrids; it’s the largest technology in terms of capacity,” … [Read more...]

Let’s Count the Many Ways Microgrids Serve the Greater Good

world's largest microgrid

If you think of microgrids as mere backup power, think again. That was the message from panelists at Microgrid 2018 who described how microgrids serve the greater good in the U.S and abroad. Their projects include electrifying parts of Somalia, helping prevent brain drain in Africa and India, cost-effectively solving a utility’s peak … [Read more...]

History of Energy in Illinois Starts and Ends with Renewables-Based Microgrids

renewable-based microgrids

Back in the 1890s, Samuel Insull, the founder of Commonwealth Edison, began providing energy in Illinois with renewables-based microgrids. More than a century later, Illinois is once again embracing renewables-based microgrids, with a handful of the most innovative microgrids now being developed and launched in Chicago. That was the engaging … [Read more...]

Will This Solar Community Microgrid Save Money AND Generate Income?

Solar Plus Storage Microgrid Features Aquion Battery at South African Luxury Camp

solar plus storage microgrid

A new solar plus storage microgrid will bring clean energy to a South African nature resort with the help of a salt water battery system by Aquion Energy. Located in Kruger National Park, the luxury nature lodge is reducing its reliance on diesel generation with the help of Aquion’s Aspen batteries. The Aspen battery uses an environmentally … [Read more...]

Why a Nanogrid in a Microgrid: Aquion Energy

nanogrid in a microgrid

Aquion Energy, Schneider Electric and Azimuth Energy have completed a nanogrid in a microgrid at the Illinois Institute of Technology. The nanogrid has the unique ability to move DC power from solar panels directly to LED lights at the Institute's Keating Sports Center. In reality, the nanogrid is a small microgrid, said Matt Maroon, vice … [Read more...]
