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...]

Duke Energy has proposed a microgrid to serve the western North Carolina town of Hot Springs as part of a larger plan that includes a $500 million investment in energy storage over 15 years. The solar-storage microgrid will bolster electric reliability for the mountainous town served only by a 10-mile, 22.86-kV feeder line, said Zachary … [Read more...]

Farewell to “If You’ve Seen One Microgrid, You’ve Seen One Microgrid”

modular microgrid

Some quotes become sticky. Such is the case with: “If you’ve seen one microgrid, you’ve seen one microgrid.” Not long after S&C Electric’s David Chiesa coined the phrase about five years ago, it became something of a mantra at industry conferences and discussions. The converse of “if you’ve seen one, you’ve seen ‘em all,” it was … [Read more...]

No More Storing Dirty Energy: California Works to Cut Emissions Due to Energy Storage

emissions

We generally think of energy storage, especially when coupled with renewable energy, as clean and green. But the California Public Utilities Commission (CPUC), through its Self-Generation Incentive Program (SGIP), has discovered that SGIP energy storage projects actually increase greenhouse gas emissions. Once again, the state is leading … [Read more...]

Nature Offers Real-Life Drama During Microgrid Tour in Wisconsin

microgrid tour

Nature decided to upstage the rest of the presenters during a microgrid tour last week at the Gordon Bubolz Nature Preserve in Appleton, Wisconsin. A massive thunderstorm hit on September 17 as about 75 members of the International Association of Electrical Inspectors (IAEI) toured the new 18,000 square-foot green building, served by the … [Read more...]

Translating DER and Microgrid Complexity into Simplicity & Bankability

microgrid technology

The California Energy Commission (CEC) wants to make microgrids more bankable. But to do so it must first translate DER and microgrid complexity into simplicity. That's the aim of a $2 million grant that the commission awarded to the Electric Power Research Institute (EPRI). In turn, EPRI has hired Bankable Energy/Xendee -- developer of … [Read more...]

New York’s Energy Storage Roadmap: It’s Not Easy Getting from Here to There

Microgrid Industry Sees Promise – Mostly – in California’s 100% Zero-Carbon Electricity Mandate

zero-carbon electricity

Clean energy continued its victory lap in California yesterday when Gov. Jerry Brown inked legislation that would require 100 percent zero-carbon electricity by 2045, a move largely praised by microgrid industry leaders -- with some cautions. The bill (SB 100) was one of several clean energy initiatives passed by California lawmakers in … [Read more...]
