How Many Hurricanes Must Slam the Grid Before We Get the Message? 

The electric grid’s dysfunctional relationship with hurricanes offers a new twist on the Humpty-Dumpty story. Again and again when fierce storms like Hurricane Ida topple wires and poles, all the king’s horses and all the king’s men do put the grid back together again. But with the next big blow, down it goes. So it was head-scratching this … [Read more...]

Reliability and Sustainability: Must They be at Odds?

Can all microgrids be 100% renewable, 100% reliable and still affordable? It’s a question that dogs the microgrid industry as it strives for low carbon energy production, but also must guarantee the power will not go out in places like hospitals and water plants. Fossil fuel generators often act as backstops at critical facilities. This week … [Read more...]

Replay of Conference Sessions on Microgrid Costs and Savings — Free through June 3

Along with many others in the Southeastern US, I found myself searching in vain for gasoline this week, a circumstance that reminded me of the importance of local energy. Somewhere far off in another country, a hacker infiltrated a US energy company, crippling a fuel supply line that runs 5,500 miles from New York to Texas and leaving me, … [Read more...]

Register By May 17 to Attend Next Week’s Sessions at Microgrid 2021: The World Awakens to Microgrids
